[PATCH v5 0/5] ia64: system call table generation support

by Firoz Khan

The purpose of this patch series is, we can easily add/modify/delete system call table support by cha- nging entry in syscall.tbl file instead of manually changing many files. The other goal is to unify the system call table generation support implementation across all the architectures. The system call tables are in different format in all architecture. It will be difficult to manually add, modify or delete the system calls in the resp- ective files manually. To make it easy by keeping a script and which'll generate uapi header file and syscall table file. syscall.tbl contains the list of available system calls along with system call number and correspond- ing entry point. Add a new system call in this arch- itecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. ARM, s390 and x86 architecuture does exist the sim- ilar support. I leverage their implementation to come up with a generic solution. I have done the same support for work for alpha, m68k, microblaze, mips, parisc, powerpc, sh, sparc and xtensa. Below mentioned git repository contains more details about the workflow. https://github.com/frzkhn/system_call_table_generator/ Finally, this is the ground work to solve the Y2038 issue. We need to add two dozen of system calls to solve Y2038 issue. So this patch series will help to add new system calls easily by adding new entry in the syscall.tbl. changes since v4: - changed from generic-y to generated-y in Kbuild. changes since v3: - optimized/updated the syscall table generation scripts. - fixed all mixed indentation issues in syscall.tbl. - added "comments" in syscall.tbl. - removed __IGNORE entries which was added in v2 to suppress the warning. changes since v2: - fixed the offset logic in the script. - added missing new line. changes since v1: - enclosed __NR_sycalls macro with __KERNEL__.

[PATCH v1 0/4] xtensa: system call table generation support

by Firoz Khan

The purpose of this patch series is, we can easily add/modify/delete system call table support by cha- nging entry in syscall.tbl file instead of manually changing many files. The other goal is to unify the system call table generation support implementation across all the architectures. The system call tables are in different format in all architecture. It will be difficult to manually add, modify or delete the system calls in the resp- ective files manually. To make it easy by keeping a script and which'll generate uapi header file and syscall table file. syscall.tbl contains the list of available system calls along with system call number and correspond- ing entry point. Add a new system call in this arch- itecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. ARM, s390 and x86 architecuture does exist the sim- ilar support. I leverage their implementation to come up with a generic solution. I have done the same support for work for alpha, ia64, m68k, microblaze, mips, parisc, powerpc, sh and sparc. Below mentioned git repository contains more details about the workflow. https://github.com/frzkhn/system_call_table_generator/ Finally, this is the ground work to solve the Y2038 issue. We need to add two dozen of system calls to solve Y2038 issue. So this patch series will help to add new system calls easily by adding new entry in the syscall.tbl.

[PATCH v4 0/6] parisc: system call table generation support

by Firoz Khan

The purpose of this patch series is, we can easily add/modify/delete system call table support by changing entry in syscall.tbl file instead of manually changing many files. The other goal is to unify the system call table generation support implementation across all the architectures. The system call tables are in different format in all architecture. It will be difficult to manually add, modify or delete the system calls in the respective files manually. To make it easy by keeping a script and which'll generate uapi header file and syscall table file. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. - Compat entry name, if required. ARM, s390 and x86 architecuture does exist the similar support. I leverage their implementation to come up with a generic solution. I have done the same support for work for alpha, microblaze, sparc, m68k, mips, powerpc, sh, sparc, and xtensa. But I started sending the patch for one architecuture for review. Below mentioned git repository contains more details. Git repo:- https://github.com/frzkhn/system_call_table_generator/ Finally, this is the ground work for solving the Y2038 issue. We need to add two dozen of system calls to solve Y2038 issue. So this patch series will help to add new system calls easily by adding new entry in the syscall.tbl.

But there are couple system call got add in the latest rc release. If run Marcin's script on latest release, it will generate a different syscall.tbl. But I still use the old file - syscall.tbl and once all review got over I'll update syscall.tbl alone w.r.to the tip of the kernel. The impact of this is, few of the system call won't work.

[RFC] parisc64: change __kernel_suseconds_t to match glibc

by Arnd Bergmann

There are only two 64-bit architecture ports that have a 32-bit suseconds_t: sparc64 and parisc64. I've encountered a number of problems with this, while trying to get a proper 64-bit time_t working on 32-bit architectures. Having a 32-bit suseconds_t combined with a 64-bit time_t means that we get extra padding in data structures that may leak kernel stack data to user space, and it breaks all code that assumes that timespec and timeval have the same layout. While we can't change sparc64, it seems that glibc on parisc64 has always set suseconds_t to 'long', and the current version would give incorrect results for gettimeofday() and many other interfaces: timestamps passed from user space into the kernel result in tv_usec being always zero (the lower bits contain the intended value but are ignored) while data passed from the kernel to user space contains either zeroes or random data in tv_usec. Based on that, it seems best to change the user API in the kernel in an incompatible way to match what glibc expects. Note that the distros I could find (gentoo and debian) all just have 32-bit user space, which does not suffer from this problem.

[PATCH net-next 1/3] net: rework SIOCGSTAMP ioctl handling

by Arnd Bergmann

The SIOCGSTAMP/SIOCGSTAMPNS ioctl commands are implemented by many socket protocol handlers, and all of those end up calling the same sock_get_timestamp()/sock_get_timestampns() helper functions, which results in a lot of duplicate code. With the introduction of 64-bit time_t on 32-bit architectures, this gets worse, as we then need four different ioctl commands in each socket protocol implementation. To simplify that, let's add a new .gettstamp() operation in struct proto_ops, and move ioctl implementation into the common sock_ioctl()/compat_sock_ioctl_trans() functions that these all go through. We can reuse the sock_get_timestamp() implementation, but generalize it so it can deal with both native and compat mode, as well as timeval and timespec structures.

[PATCH 0/5] System call table generation support

by Firoz Khan

The purpose of this patch series is: 1. We can easily add/modify/delete system call by changing entry in syscall.tbl file. No need to manually edit many files. 2. It is easy to unify the system call implementation across all the architectures. The system call tables are in different format in all architecture and it will be difficult to manually add or modify the system calls manually in the respective files. To make it easy by keeping a script and which'll generate the header file and syscall table file so this change will unify the implementation across all architectures. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. ARM, s390 and x86 architecuture does exist the similar support. I leverage their implementation to come up with a generic solution. I have done the same support for work for alpha, m68k, microblaze, mips, parisc, powerpc, sh, sparc, and xtensa. But I started sending the patch for one architecuture for review. Below mentioned git repository contains more details. Git repo:- https://github.com/frzkhn/system_call_table_generator/ Finally, this is the ground work for solving the Y2038 issue. We need to add/change two dozen of system calls to solve Y2038 issue. So this patch series will help to easily modify from existing system call to Y2038 compatible system calls. I started working system call table generation on 4.17-rc1. I used marcin's script - https://github.com/hrw/syscalls-table to generate the syscall.tbl file. And this will be the input to the system call table generation script. But there are couple system call got add in the latest rc release. If run Marcin's script on latest release, it will generate a different syscall.tbl. But I still use the old file - syscall.tbl and once all review got over I'll update syscall.tbl alone w.r.to the tip of the kernel. The impact of this is, few of the system call won't work.

Hi Thomas, Please pull the system call changes into a branch of the tip tree. These are the ones I posted right after rc1, with the addition of two bug fixes that were contributed by Guenther and the kbuild test robot. I've had the changes in linux-next since then and not received any other bug reports or feedback. I panicked a little at one point when I realized that there is a sparc64 specific bug in some of my patches, but I then found that at least this series is not affected at all. Arnd The following changes since commit 5b394b2ddf0347bef56e50c69a58773c94343ff3: Linux 4.19-rc1 (2018-08-26 14:11:59 -0700) are available in the Git repository at: git+ssh://git@ra.kernel.org:/pub/scm/linux/kernel/git/arnd/playground.git tags/y2038 for you to fetch changes up to 67314ec7b0250290cc85eaa7a2f88a8ddb9e8547: RISC-V: Request newstat syscalls (2018-09-05 22:44:21 +0200) ---------------------------------------------------------------- y2038: convert more syscalls Here is another set of system call changes to prepare the change over to 64-bit time_t. As before, the strategy is to change system calls that take a 'struct timespec' argument over to 'struct __kernel_timespec', which for now is defined to be the same but will get redefined to use a 64-bit time_t argument once we are ready to modify the system call tables. The major change from previous patches is that the plan is no longer to directly use the 'compat' system calls for providing compatibility with the existing 32-bit time_t based entry points. Instead, we rename the compat code to something that makes more sense on 32-bit architectures, e.g. compat_timespec becomes old_timespec32. With the renamed types in place, we change over the 'stat' and 'utimes' families of system calls, sched_rr_get_interval, recvmmsg and rt_sigtimedwait. Another series for poll, select and io_pgetevents is currently being tested. ---------------------------------------------------------------- Arnd Bergmann (14): y2038: remove unused time interfaces y2038: make do_gettimeofday() and get_seconds() inline y2038: globally rename compat_time to old_time32 y2038: Remove newstat family from default syscall set y2038: Remove stat64 family from default syscall set asm-generic: Move common compat types to asm-generic/compat.h asm-generic: Remove unneeded __ARCH_WANT_SYS_LLSEEK macro asm-generic: Remove empty asm/unistd.h y2038: Change sys_utimensat() to use __kernel_timespec y2038: Compile utimes()/futimesat() conditionally y2038: utimes: Rework #ifdef guards for compat syscalls y2038: sched: Change sched_rr_get_interval to use __kernel_timespec y2038: socket: Change recvmmsg to use __kernel_timespec y2038: signal: Change rt_sigtimedwait to use __kernel_timespec Guenter Roeck (1): RISC-V: Request newstat syscalls kbuild test robot (1): y2038: __get_old_timespec32() can be static arch/alpha/include/asm/unistd.h | 2 ++ arch/arc/include/uapi/asm/unistd.h | 1 + arch/arm/include/asm/unistd.h | 4 ++-- arch/arm64/include/asm/compat.h | 26 +++++--------------------- arch/arm64/include/asm/stat.h | 2 +- arch/arm64/include/asm/unistd.h | 2 +- arch/arm64/include/uapi/asm/unistd.h | 1 + arch/c6x/include/uapi/asm/unistd.h | 1 + arch/h8300/include/uapi/asm/unistd.h | 1 + arch/hexagon/include/uapi/asm/unistd.h | 1 + arch/ia64/include/asm/unistd.h | 3 +++ arch/m68k/include/asm/unistd.h | 2 +- arch/microblaze/include/asm/unistd.h | 2 +- arch/mips/include/asm/compat.h | 28 +++++----------------------- arch/mips/include/asm/unistd.h | 3 ++- arch/mips/kernel/binfmt_elfn32.c | 14 +++++++------- arch/mips/kernel/binfmt_elfo32.c | 14 +++++++------- arch/nds32/include/uapi/asm/unistd.h | 1 + arch/nios2/include/uapi/asm/unistd.h | 1 + arch/openrisc/include/uapi/asm/unistd.h | 1 + arch/parisc/include/asm/compat.h | 24 +++++------------------- arch/parisc/include/asm/unistd.h | 3 ++- arch/powerpc/include/asm/compat.h | 24 +++++------------------- arch/powerpc/include/asm/unistd.h | 3 ++- arch/powerpc/kernel/asm-offsets.c | 8 ++++---- arch/powerpc/oprofile/backtrace.c | 2 +- arch/riscv/include/asm/unistd.h | 1 + arch/s390/include/asm/compat.h | 18 ++---------------- arch/s390/include/asm/unistd.h | 3 ++- arch/sh/include/asm/unistd.h | 2 +- arch/sparc/include/asm/compat.h | 25 +++++-------------------- arch/sparc/include/asm/unistd.h | 3 ++- arch/unicore32/include/uapi/asm/unistd.h | 1 + arch/x86/include/asm/compat.h | 19 ++----------------- arch/x86/include/asm/unistd.h | 3 ++- arch/xtensa/include/asm/unistd.h | 2 +- fs/aio.c | 8 ++++---- fs/compat_binfmt_elf.c | 2 +- fs/read_write.c | 2 +- fs/select.c | 20 ++++++++++---------- fs/stat.c | 3 +++ fs/timerfd.c | 12 ++++++------ fs/utimes.c | 73 +++++++++++++++++++++++++++++++++++-------------------------------------- include/asm-generic/compat.h | 24 +++++++++++++++++++++++- include/asm-generic/unistd.h | 13 ------------- include/linux/compat.h | 101 +++++++++++++++++++++++++++++++++++++++++++++++------------------------------------------------------ include/linux/compat_time.h | 32 -------------------------------- include/linux/elfcore-compat.h | 8 ++++---- include/linux/restart_block.h | 4 ++-- include/linux/socket.h | 4 ++-- include/linux/syscalls.h | 21 ++++++++++++--------- include/linux/time32.h | 78 +++++++++++++++++++++++++++++++++++++++++------------------------------------- include/linux/timekeeping.h | 12 ------------ include/linux/timekeeping32.h | 53 +++++++---------------------------------------------- include/uapi/asm-generic/unistd.h | 2 ++ ipc/mqueue.c | 8 ++++---- ipc/msg.c | 6 +++--- ipc/sem.c | 10 +++++----- ipc/shm.c | 6 +++--- ipc/syscall.c | 2 +- ipc/util.h | 2 +- kernel/compat.c | 8 ++++---- kernel/futex_compat.c | 2 +- kernel/sched/core.c | 8 ++++---- kernel/signal.c | 19 ++++++++++--------- kernel/time/hrtimer.c | 8 ++++---- kernel/time/posix-stubs.c | 18 +++++++++--------- kernel/time/posix-timers.c | 30 +++++++++++++++--------------- kernel/time/time.c | 97 ++++++++++++++++++++++++++++++++++++++----------------------------------------------------------- kernel/time/timekeeping.c | 24 ------------------------ net/compat.c | 10 +++++----- net/socket.c | 18 ++++++++---------- 72 files changed, 398 insertions(+), 601 deletions(-) delete mode 100644 include/asm-generic/unistd.h delete mode 100644 include/linux/compat_time.h Reply Forward

[PATCH 1/5] media: dvb: fix compat ioctl tramslation

by Arnd Bergmann

The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but it never worked because the command number is wrong. Using the right command number means we have a better chance of them actually doing the right thing, though clearly nobody has ever tried it successfully. I noticed these while auditing the remaining users of compat_time_t for y2038 bugs. This one is fine in that regard, it just never did anything.

[PATCH net-next 1/5] pppoe: fix PPPOEIOCSFWD compat handling

by Arnd Bergmann

Support for handling the PPPOEIOCSFWD ioctl in compat mode was added in linux-2.5.69 along with hundreds of other commands, but was always broken sincen only the structure is compatible, but the command number is not, due to the size being sizeof(size_t), or at first sizeof(sizeof((struct sockaddr_pppox)), which is different on 64-bit architectures. Fix it by defining a separate command code that matches the 32-bit version, and marking that one as compatible. This should apply to all stable kernels.

[PATCH 00/14] y2038 syscall changes for 4.20

by Arnd Bergmann

Hi Thomas, I've rebased the syscall changes on top of 4.19-rc1, and the old_time32 rename. This is the first set of those patches, the ones that I hope are all uncontroversial and obvious now.

[PATCH] y2038: provide aliases for compat helpers

by Arnd Bergmann

As part of the system call rework for 64-bit time_t, we are restructuring the way that compat syscalls deal with 32-bit time_t, reusing the implementation for 32-bit architectures. Christoph Hellwig suggested a rename of the associated types and interfaces to avoid the confusing usage of the 'compat' prefix for 32-bit architectures. To prepare for doing that in linux-4.20, this adds a set of macros that lets us convert subsystems separately to the new names and avoid some of the nastier merge conflicts.

[PATCH 0/6] System call table generation support

by Firoz Khan

The goal of this patch series is to easily add/modify/delete a system call by changing entry in syscall.tbl file. No need to manually edit many files. The another goal of this patch series is to to unify the system call implementation across all the architectures. ARM, s390 and x86 architecuture does have the similar support. I leverage their implementation to come up with a generic solution. I have done the same support for work for ia64, m68k, microblaze, mips, parisc, powerpc, sh, sparc, and xtensa. But I started sending the patch for one architecuture for review. Below mentioned git repository contains more details. Git repo:- https://github.com/frzkhn/system_call_table_generator/ Finally, this is the ground work for solving the Y2038 issue. We need to change two dozen of system calls to solve Y2038 issue. So this implementation will help to easily modify from existing system call to Y2038 compatible system calls. Firoz Khan (6): alpha: Move __IGNORE* entries to non uapi header alpha: Add CONFIG_OSF4_COMPAT for compat syscall support alpha: Unify the not-implemented system call entry name alpha: Replace NR_SYSCALLS macro from asm/unistd.h alpha: Add system call table generation support alpha: uapi header and system call table file generation arch/alpha/Makefile | 3 + arch/alpha/include/asm/Kbuild | 3 +- arch/alpha/include/asm/unistd.h | 7 +- arch/alpha/include/uapi/asm/Kbuild | 2 + arch/alpha/include/uapi/asm/unistd.h | 489 --------------------------- arch/alpha/kernel/Makefile | 2 +- arch/alpha/kernel/entry.S | 4 +- arch/alpha/kernel/osf_sys.c | 9 +- arch/alpha/kernel/syscall.S | 20 ++ arch/alpha/kernel/syscalls/Makefile | 37 +++ arch/alpha/kernel/syscalls/syscall.tbl | 450 +++++++++++++++++++++++++ arch/alpha/kernel/syscalls/syscallhdr.sh | 33 ++ arch/alpha/kernel/syscalls/syscalltbl.sh | 28 ++ arch/alpha/kernel/systbls.S | 552 ------------------------------- 14 files changed, 589 insertions(+), 1050 deletions(-) delete mode 100644 arch/alpha/include/uapi/asm/unistd.h create mode 100644 arch/alpha/kernel/syscall.S create mode 100644 arch/alpha/kernel/syscalls/Makefile create mode 100644 arch/alpha/kernel/syscalls/syscall.tbl create mode 100644 arch/alpha/kernel/syscalls/syscallhdr.sh create mode 100644 arch/alpha/kernel/syscalls/syscalltbl.sh delete mode 100644 arch/alpha/kernel/systbls.S -- 2.7.4

[PATCH 1/3] hfs: stop using timespec based interfaces

by Arnd Bergmann

The native HFS timestamps overflow in year 2040, two years after the Unix y2038 overflow. However, the way that the conversion between on-disk timestamps and in-kernel timestamps was implemented, 64-bit machines actually ended up converting negative UTC timestamps (1902 through 1969) into times between 2038 and 2106. Rather than making all machines faithfully represent timestamps in the ancient past but break after 2040, this changes the file system to always use the unsigned UTC interpretation, reading back times between 1970 and 2106.

[PATCH] vfs: replace current_kernel_time64 with ktime equivalent

by Arnd Bergmann

current_time is the last remaining caller of current_kernel_time64(), which is a wrapper around ktime_get_coarse_real_ts64(). This calls the latter directly for consistency with the rest of the kernel that is moving to the ktime_get_ family of time accessors, as now documented in Documentation/core-api/timekeeping.rst. An open questions is whether we may want to actually call the more accurate ktime_get_real_ts64() for file systems that save high-resolution timestamps in their on-disk format. This would add a small overhead to each update of the inode stamps but lead to inode timestamps to actually have a usable resolution better than one jiffy (1 to 10 milliseconds normally). Experiments on a variety of hardware platforms show a typical time of around 100 CPU cycles to read the cycle counter and calculate the accurate time from that. On old platforms without a cycle counter, this can be signiciantly higher, up to several microseconds to access a hardware clock, but those have become very rare by now. I traced the original addition of the current_kernel_time() call to set the nanosecond fields back to linux-2.5.48, where Andi Kleen added a patch with subject "nanosecond stat timefields". Andi explains that the motivation was to introduce as little overhead as possible back then. At this time, reading the clock hardware was also more expensive when most architectures did not have a cycle counter. One side effect of having more accurate inode timestamp would be having to write out the inode every time that mtime/ctime/atime get touched on most systems, whereas many file systems today only write it when the timestamps have changed, i.e. at most once per jiffy unless something else changes as well. That change would certainly be noticed in some workloads, which is enough reason to not do it without a good reason, regardless of the cost of reading the time. One thing we could still consider however would be to round the timestamps from current_time() to multiples of NSEC_PER_JIFFY, e.g. full milliseconds rather than having six or seven meaningless but confusing digits at the end of the timestamp.

[PATCH v2 1/4] sh: dreamcast: rtc: push down rtc class ops into driver

by Arnd Bergmann

The dreamcast RTC support has an extra level of indirection to provide either the old read_persistent_clock/update_persistent_clock interface or the rtc-generic device for hctosys/systohc. Both do the same thing here, so we can do away with the abstraction and simply enable the RTC core code to take care of it.

[PATCH 1/2] [v2] hfs/hfsplus: follow MacOS time behavior

by Arnd Bergmann

According to the official documentation for HFS+ [1], inode timestamps are supposed to cover the time range from 1904 to 2040 as originally used in classic MacOS. The traditional Linux usage is to convert the timestamps into an unsigned 32-bit number based on the Unix epoch and from there to a time_t. On 32-bit systems, that wraps the time from 2038 to 1902, so the last two years of the valid time range become garbled. On 64-bit systems, all times before 1970 get turned into timestamps between 2038 and 2106, which is more convenient but also different from the documented behavior. Looking at the Darwin sources [2], it seems that MacOS is inconsistent in yet another way: all timestamps are wrapped around to a 32-bit unsigned number when written to the disk, but when read back, all numeric values lower than 2082844800U are assumed to be invalid, so we cannot represent the times before 1970 or the times after 2040. While all implementations seem to agree on the interpretation of values between 1970 and 2038, they often differ on the exact range they support when reading back values outside of the common range: MacOS (traditional): 1904-2040 Apple Documentation: 1904-2040 MacOS X source comments: 1970-2040 MacOS X source code: 1970-2038 32-bit Linux: 1902-2038 64-bit Linux: 1970-2106 hfsfuse: 1970-2040 hfsutils (32 bit, old libc) 1902-2038 hfsutils (32 bit, new libc) 1970-2106 hfsutils (64 bit) 1904-2040 hfsplus-utils 1904-2040 hfsexplorer 1904-2040 7-zip 1904-2040 This changes Linux over to mostly the same behavior as described in the code comment in MacOS X, disallowing all times before 1970 and after 2040, while still allowing times between 2038 and 2040 like most other implementations do. Most importantly, it means we can have the same behavior on 32-bit and 64-bit.

[PATCH] [RESEND] firewire: ohci: stop using get_seconds() for BUS_TIME

by Arnd Bergmann

The ohci driver uses the get_seconds() function to implement the 32-bit CSR_BUS_TIME register. This was added in 2010 commit a48777e03ad5 ("firewire: add CSR BUS_TIME support"). As get_seconds() returns a 32-bit value (on 32-bit architectures), it seems like a good fit for that register, but it is also deprecated because of the y2038/y2106 overflow problem, and should be replaced throughout the kernel with either ktime_get_real_seconds() or ktime_get_seconds(). I'm using the latter here, which uses monotonic time. This has the advantage of behaving better during concurrent settimeofday() updates or leap second adjustments and won't overflow a 32-bit integer, but the downside of using CLOCK_MONOTONIC instead of CLOCK_REALTIME is that the observed values are not related to external clocks. If we instead need UTC but can live with clock jumps or overflows, then we should use ktime_get_real_seconds() instead, retaining the existing behavior.

[PATCH 1/3] [v2] powerpc: mac: fix rtc read/write functions

by Arnd Bergmann

As Mathieu pointed out, my conversion to time64_t was incorrect and resulted in negative times to be read from the RTC. The problem is that during the conversion from a byte array to a time64_t, the 'unsigned char' variable holding the top byte gets turned into a negative signed 32-bit integer before being assigned to the 64-bit variable for any times after 1972. This changes the logic to cast to an unsigned 32-bit number first for the Macintosh time and then convert that to the Unix time, which then gives us a time in the documented 1904..2040 year range. I decided not to use the longer 1970..2106 range that other drivers use, for consistency with the literal interpretation of the register, but that could be easily changed if we decide we want to support any Mac after 2040. Just to be on the safe side, I'm also adding a WARN_ON that will trigger if either the year 2040 has come and is observed by this driver, or we run into an RTC that got set back to a pre-1970 date for some reason (the two are indistinguishable). For the RTC write functions, Andreas found another problem: both pmu_request() and cuda_request() are varargs functions, so changing the type of the arguments passed into them from 32 bit to 64 bit breaks the API for the set_rtc_time functions. This changes it back to 32 bits. The same code exists in arch/m68k/ and is patched in an identical way now in a separate patch.

While working on extended rand for last_error/first_error timestamps, I noticed that the endianess is wrong, we access the little-endian fields in struct ext4_super_block as native-endian when we print them.

[PATCH v2 00/17] y2038: system calls, part 3

by Arnd Bergmann

This is a mostly unchanged copy of a series I sent back in April for an initial review. All the earlier syscall patches that Deepa or I sent got merged now, and this is the largest chunk of remaining patches. Changes this time are: - This is actually tested with the LTP syscalls test suite, both before and after the CONFIG_64BIT_TIME change (which is not included here). I have created a patch series for musl libc to use 64-bit time_t and change all the system calls over to the new entry points for this. The only bugs I found during that testing were in later parts of the conversion that I have not posted yet. - I rewrote the sys_io_getevents conversion after the introduction of sys_sys_io_getevents. We obviously don't need to have two of each, so we will only provide sys_io_pgetevents() with 64-bit time_t but not sys_io_getevents(), which the libc can implement on top of the former. - While we have Deepa's POSIX timer conversion merged now, we still need to decide on how we want to do the replacement ABI for getitimer()/setitimer(). Like getrusage()/waitid() and clock_adjtime() and unlike the system calls I'm posting here, there is no one obvious ABI. - For ppoll()/pselect6(), the ABI is fairly clear, but the implementation still needs to be done. I tested with a simple prototype based on the existing compat code, but we can probably improve that. This is something that Deepa still wants to work on. - Finally, Christoph Hellwig objected to the idea of reusing the compat_ namespace for the 32-bit native case. Changing that would be a departure from our plans so far[2], and would make some things end up differently. Until we have decided on how this is to be done, I've decided to not change the code for this post. We can clearly rename all the symbols and I've implemented that in [3] for the current linux-next (not including the series here). This is something we can definitely do, but I'd need to know soon whether we can merge this series unchanged for 4.19 or if I should rebase it on top of that patch with the alternative naming. Arnd --- Previous cover letter announcement below, see [4] for the full series: After the first timekeeping series from Deepa (merged into -tip now) and my follow-up for IPC system calls, this is a third set of system call conversions following the same principle. Most of the changes are straightforward, so I'm grouping them into a larger series even though the system calls are mostly unrelated to one another. After this series, the remaining calls that need to be changed are getrusage()/waitid(), pselect6/ppoll(), timer{,fd}_{get,set}time() and getitimer()/setitimer(). Those will be sent separately, once they are matured enough. To put the changes into perspective, a list of all system calls that require changes is available in a spreadsheet[5] and I have made another experimental patch that changes over x86[6] and arm[7] to actually use them.

[PATCH 1/2] [RESEND] jffs2: use 64-bit intermediate timestamps

by Arnd Bergmann

The VFS now uses timespec64 timestamps consistently, but jffs2 still converts them to 32-bit numbers on the storage medium. As the helper functions for the conversion (get_seconds() and timespec_to_timespec64()) are now deprecated, let's change them over to the more modern replacements. This keeps the traditional interpretation of those values, where the on-disk 32-bit numbers are taken to be negative numbers, i.e. dates before 1970, on 32-bit machines, but future numbers past 2038 on 64-bit machines. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- I originally sent these two patches on Jun 19, but got no reply aside from a harmless sparse warning reported by the kbuild test robot. Looking at the git history for jffs2, it seems that David Woodhouse hasn't applied any patches for over two years, so I suppose he's not taking these either. Al or Andrew, could you pick these up instead? --- fs/jffs2/dir.c | 32 ++++++++++++++++---------------- fs/jffs2/file.c | 6 +++--- fs/jffs2/fs.c | 12 ++++++------ fs/jffs2/os-linux.h | 3 ++- 4 files changed, 27 insertions(+), 26 deletions(-) diff --git a/fs/jffs2/dir.c b/fs/jffs2/dir.c index b2944f9218f7..f20cff1194bb 100644 --- a/fs/jffs2/dir.c +++ b/fs/jffs2/dir.c @@ -201,7 +201,7 @@ static int jffs2_create(struct inode *dir_i, struct dentry *dentry, if (ret) goto fail;

[PATCH 1/3] [RESEND] ufs: use ktime_get_real_seconds for sb and cg timestamps

by Arnd Bergmann

get_seconds() is deprecated because of the 32-bit overflow and will be removed. All callers in ufs also truncate to a 32-bit number, so nothing changes during the conversion, but this should be harmless as the superblock and cylinder group timestamps are not visible to user space, except for checking the fs-dirty state, wich works fine across the overflow. This moves the call to get_seconds() into a new inline function, with a comment explaining the constraints, while converting it to ktime_get_real_seconds().

[PATCH] [RFC] y2038: globally rename compat_time to old_time32

by Arnd Bergmann

Christoph Hellwig suggested a slightly different path for handling backwards compatibility with the 32-bit time_t based system calls: Rather than simply reusing the compat_sys_* entry points on 32-bit architectures unchanged, we get rid of those entry points and the compat_time types by renaming them to something that makes more sense on 32-bit architectures (which don't have a compat mode otherwise), and then share the entry points under the new name with the 64-bit architectures that use them for implementing the compatibility. The following types and interfaces are renamed here, and moved from linux/compat_time.h to linux/time32.h: old new --- --- compat_time_t old_time32_t struct compat_timeval struct old_timeval32 struct compat_timespec struct old_timespec32 struct compat_itimerspec struct old_itimerspec32 ns_to_compat_timeval() ns_to_old_timeval32() get_compat_itimerspec64() get_old_itimerspec32() put_compat_itimerspec64() put_old_itimerspec32() compat_get_timespec64() get_old_timespec32() compat_put_timespec64() put_old_timespec32() I considered doing this only for those instances that are actually shared between 32-bit and 64-bit kernels, but doing it everywhere avoids duplication. This should make more sense for the 32-bit implementation, and the naming suggests that these interfaces are meant for 'old' syscalls only, and that they always operate on 32-bit time_t on both 32-bit and 64-bit architectures, something that may not be obvious from the compat_* naming. I'm not renaming the timex, rusage and itimerval structures, as we are still debating what the new interface will look like, and whether we will need a replacement at all. This also doesn't change the names of the syscall entry points, which can be done more easily when we actually switch over the 32-bit architectures to use them, at that point we need to change COMPAT_SYSCALL_DEFINEx to SYSCALL_DEFINEx with a new name, e.g. with a _time32 suffix. Suggested-by: Christoph Hellwig <hch(a)infradead.org> Link: https://lore.kernel.org/lkml/20180705222110.GA5698@infradead.org/ Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- Both Deepa and I have pending syscall conversion patches, but if we can get consensus on the rename, they should be easy to rebase on top of this patch. The patch would be easy to split up in various ways, but since it is a trivial rename, I went for a big patch with the first attempt. --- arch/arm64/include/asm/compat.h | 6 +- arch/arm64/include/asm/stat.h | 2 +- arch/mips/include/asm/compat.h | 6 +- arch/mips/kernel/binfmt_elfn32.c | 14 ++-- arch/mips/kernel/binfmt_elfo32.c | 14 ++-- arch/parisc/include/asm/compat.h | 6 +- arch/powerpc/include/asm/compat.h | 6 +- arch/powerpc/kernel/asm-offsets.c | 8 +-- arch/powerpc/oprofile/backtrace.c | 2 +- arch/sparc/include/asm/compat.h | 6 +- drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 4 +- fs/aio.c | 8 +-- fs/compat_binfmt_elf.c | 2 +- fs/compat_ioctl.c | 6 +- fs/select.c | 20 +++--- fs/timerfd.c | 12 ++-- fs/utimes.c | 12 ++-- fs/xfs/xfs_ioctl32.c | 2 +- fs/xfs/xfs_ioctl32.h | 2 +- include/linux/compat.h | 96 +++++++++++++-------------- include/linux/compat_time.h | 32 --------- include/linux/elfcore-compat.h | 8 +-- include/linux/restart_block.h | 4 +- include/linux/syscalls.h | 2 +- include/linux/time32.h | 25 +++++++ ipc/mqueue.c | 8 +-- ipc/msg.c | 6 +- ipc/sem.c | 10 +-- ipc/shm.c | 6 +- ipc/syscall.c | 2 +- ipc/util.h | 2 +- kernel/compat.c | 8 +-- kernel/futex_compat.c | 2 +- kernel/sched/core.c | 4 +- kernel/signal.c | 2 +- kernel/time/hrtimer.c | 8 +-- kernel/time/posix-stubs.c | 18 ++--- kernel/time/posix-timers.c | 30 ++++----- kernel/time/time.c | 58 ++++++++-------- net/bluetooth/hci_sock.c | 2 +- net/compat.c | 22 +++--- sound/core/pcm_compat.c | 14 ++-- sound/core/rawmidi_compat.c | 2 +- sound/core/timer_compat.c | 2 +- 44 files changed, 252 insertions(+), 259 deletions(-) delete mode 100644 include/linux/compat_time.h diff --git a/arch/arm64/include/asm/compat.h b/arch/arm64/include/asm/compat.h index 1a037b94eba1..4a89007db14a 100644 --- a/arch/arm64/include/asm/compat.h +++ b/arch/arm64/include/asm/compat.h @@ -86,11 +86,11 @@ struct compat_stat { compat_off_t st_size;

[PATCH 1/5] ceph: use timespec64 in for keepalive

by Arnd Bergmann

ceph_con_keepalive_expired() is the last user of timespec_add() and some of the last uses of ktime_get_real_ts(). Replacing this with timespec64 based interfaces lets us remove that deprecated API. I'm introducing new ceph_encode_timespec64()/ceph_decode_timespec64() here that take timespec64 structures and convert to/from ceph_timespec, which is defined to have an unsigned 32-bit tv_sec member. This extends the range of valid times to year 2106, avoiding the year 2038 overflow. The ceph file system portion still uses the old functions for inode timestamps, this will be done separately after the VFS layer is converted.

[PATCH] [v2] bcache: stop using the deprecated get_seconds()

by Arnd Bergmann

The get_seconds function is deprecated now since it returns a 32-bit value that will eventually overflow, and we are replacing it throughout the kernel with ktime_get_seconds() or ktime_get_real_seconds() that return a time64_t. bcache uses get_seconds() to read the current system time and store it in the superblock as well as in uuid_entry structures that are user visible. Unfortunately, the two structures in are still limited to 32 bits, so this won't fix any real problems but will still overflow in year 2106. Let's at least document that properly, in case we get an updated format in the future it can be fixed. We still have a long time before the overflow and checking the tools at https://github.com/koverstreet/bcache-tools reveals no access to any of them.

[PATCH] [RESEND] sysvfs: use ktime_get_real_seconds() for superblock stamp

by Arnd Bergmann

get_seconds() is deprecated in favor of ktime_get_real_seconds(), which returns a 64-bit timestamp. In the SYSV file system, the superblock timestamp is only 32 bits wide, and it is used to check whether a file system is clean, so the best solution seems to be to force a wraparound and explicitly convert it to an unsigned 32-bit value. This is independent of the inode timestamps that are also 32-bit wide on disk and that come from current_time().

[PATCH 1/2] [PATCHES] jffs2: use 64-bit intermediate timestamps

by Arnd Bergmann

The VFS now uses timespec64 timestamps consistently, but jffs2 still converts them to 32-bit numbers on the storage medium. As the helper functions for the conversion (get_seconds() and timespec_to_timespec64()) are now deprecated, let's change them over to the more modern replacements. This keeps the traditional interpretation of those values, where the on-disk 32-bit numbers are taken to be negative numbers, i.e. dates before 1970, on 32-bit machines, but future numbers past 2038 on 64-bit machines. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- I originally sent these two patches on Jun 19, but got no reply aside from a harmless sparse warning reported by the kbuild test robot. Looking at the git history for jffs2, it seems that David Woodhouse hasn't applied any patches for over two years, so I suppose he's not taking these either.

[PATCH v2 0/7] Introduce struct __kernel_timex

by Deepa Dinamani

The series introduces struct __kernel_timex as a substitute for the non y2038 safe struct timex. The series is based on the original series posted by Arnd Bergmann in [1]. The overview of the series is as below: 1. Prepare for the compat timex interfaces to be used unconditionally. 2. Introduce struct __kernel_timex. 3. Use struct __kernel_timex in place of struct timex. 4. Switch syscalls to use struct __kernel_timex.

[PATCH] drm/msm: avoid using 'timespec'

The timespec structure and associated interfaces are deprecated and will be removed in the future because of the y2038 overflow. The use of ktime_to_timespec() in timeout_to_jiffies() does not suffer from that overflow, but is easy to avoid by just converting the ktime_t into jiffies directly.

[PATCH] [RESEND] firewire: use 64-bit time_t based interfaces

by Arnd Bergmann

32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2 ioctl, we already support 64-bit timestamps, but the implementation still uses timespec. This changes the code to use timespec64 instead with the appropriate accessor functions. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- Sent originally on Jun 18, but got not reply.

[PATCH] hfs/hfsplus: use documented official timestamp range

by Arnd Bergmann

According to the official documentation for HFS+ [1], inode timestamps are supposed to cover the time range from 1904 to 2040 as originally used in classic MacOS. The traditional Linux usage is to convert the timestamps into an unsigned 32-bit number based on the Unix epoch and from there to a time_t. On 32-bit systems, that wraps the time from 2038 to 1902, so the last two years of the valid time range become garbled. On 64-bit systems, all times before 1970 get turned into timestamps between 2038 and 2106, which is more convenient but also different from the documented behavior. The same behavior is used in Darwin and presumaby all versions of MacOS X, as seen in the to_hfs_time() function in [2]. It is unclear whether this is a bug in the file system code, or intentional but undocumented behavior. This changes Linux over to the traditional MacOS (pre MacOS X) behavior. This means all files that are created on MacOS X or Linux with future timestamps between 2040 and 2106 will now show up as past dates. Timestamps between 2038 and 2040 will still be represented incorrectly on 32-bit architectures as times between 1902 and 1904, but that will be fixed once we have user space with 64-bit time_t.

[PATCH 1/4] cfg80211: track time using boottime

by Arnd Bergmann

The cfg80211 layer uses get_seconds() to read the current time in its supend handling. This function is deprecated because of the 32-bit time_t overflow, and it can cause unexpected behavior when the time changes due to settimeofday() calls or leap second updates. In many cases, we want to use monotonic time instead, however cfg80211 explicitly tracks the time spent in suspend, so this changes the driver over to use ktime_get_boottime_seconds(), which is slightly slower, but not used in a fastpath here.

[PATCH] infiniband: i40iw, nes: don't use wall time for TCP sequence numbers

by Arnd Bergmann

The nes infiniband driver uses current_kernel_time() to get a nanosecond granunarity timestamp to initialize its tcp sequence counters. This is one of only a few remaining users of that deprecated function, so we should try to get rid of it. Aside from using a deprecated API, there are several problems I see here: - Using a CLOCK_REALTIME based time source makes it predictable in case the time base is synchronized. - Using a coarse timestamp means it only gets updated once per jiffie, making it even more predictable in order to avoid having to access the hardware clock source - The upper 2 bits are always zero because the nanoseconds are at most 999999999. For the Linux TCP implementation, we use secure_tcp_seq(), which appears to be appropriate here as well, and solves all the above problems. I'm doing the same change in both versions of the nes driver, with i40iw being a later copy of the same code.

[PATCH] Documentation: document ktime_get_*() APIs

by Arnd Bergmann

As Dave Chinner points out, we don't have a proper documentation for the ktime_get() family of interfaces, making it rather unclear which of the over 30 (!) interfaces one should actually use in a driver or elsewhere in the kernel. I wrote up an explanation from how I personally see the interfaces, documenting what each of the functions do and hopefully making it a bit clearer which should be used where. This is the first time I tried writing .rst format documentation, so in addition to any mistakes in the content, I probably also introduce nonstandard formatting ;-) I first tried to add an extra section to Documentation/timers/timekeeping.txt, but this is currently not included in the generated API, and it seems useful to have the API docs as part of what gets generated in https://www.kernel.org/doc/html/latest/core-api/index.html#core-utilities instead, so I started a new file there. I also considered adding the documentation inline in the include/linux/timekeeping.h header, but couldn't figure out how to do that in a way that would result both in helpful inline comments as well as readable html output, so I settled for the latter, with a small note pointing to it from the header.

[PATCH] vfs: replace current_kernel_time64 with ktime equivalent

by Arnd Bergmann

current_time is one of the few callers of current_kernel_time64(), which is a wrapper around ktime_get_coarse_real_ts64(). This calls the latter directly for consistency with the rest of the kernel that is moving to the ktime_get_ family of time accessors. An open questions is whether we may want to actually call the more accurate ktime_get_real_ts64() for file systems that save high-resolution timestamps in their on-disk format. This would add a small but measurable overhead to each update of the inode stamps but lead to inode timestamps to actually have a usable resolution better than one jiffy (1 to 10 milliseconds normally). I traced the original addition of the current_kernel_time() call to set the nanosecond fields back to linux-2.5.48, where Andi Kleen added a patch with subject "nanosecond stat timefields". This adds the original call to current_kernel_time and the truncation to the resolution of the file system, but makes no mention of the intended accuracy. At the time, we had a do_gettimeofday() interface that on some architectures could return a microsecond-resolution timestamp, but there was no interface for getting an accurate timestamp in nanosecond resolution, neither inside the kernel nor from user space. This makes me suspect that the use of coarse timestamps was never really a conscious decision but instead a result of whatever API was available 16 years ago.

[PATCH] scsi: lpfc: use monotonic timestamps for statistics

by Arnd Bergmann

The get_seconds() function suffers from a possible overflow in 2038 or 2106, as well as jitter due to settimeofday or leap second updates, and is deprecated. As we are interested in elapsed time only, using ktime_get_seconds() to read the CLOCK_MONOTONIC timebase is ideal here. This also lets us remove the hack that tries to deal with get_seconds() going slightly backwards, which cannot happen with montonic timestamps.

[PATCH] scsi_transport_fc: use 64-bit timestamps consistently

by Arnd Bergmann

The get_seconds() helper returns an 'unsigned long' value, which can overflow on 32-bit architectures. Since the interface we pass it into already uses a 64-bit type, we can just use ktime_get_real_seconds() instead. While we generally prefer local timestamps in CLOCK_MONOTONIC format (ktime_get_seconds), this keeps using the CLOCK_REALTIME version in order to maintain compatibility with existing code.

[PATCH] aacraid: stop using deprated get_seconds()

by Arnd Bergmann

get_seconds() can overflow on 32-bit architectures and is deprecated because of that. The use in the aacraid driver has the same problem due to a limited firmware interface, it also overflows in the year 2106. This changes all calls to get_seconds() to the non-deprecated ktime_get_real_seconds(), which unfortunately doesn't solve that problem but gets rid of one user of the deprecated interface.

[PATCH v2 1/2] y2038: rusage: Use __kernel_old_timeval for process times

by Arnd Bergmann

'struct rusage' contains the run times of a process in 'timeval' format and is accessed through the wait4() and getrusage() system calls. This is not a problem for y2038 safety by itself, but causes an issue when the C library starts using 64-bit time_t on 32-bit architectures because the structure layout becomes incompatible. There are three possible ways of dealing with this: a) deprecate the wait4() and getrusage() system calls, and create a set of kernel interfaces based around a newly defined structure that could solve multiple problems at once, e.g. provide more fine-grained timestamps. The C library could then implement the posix interfaces on top of the new system calls. b) Extend the approach taken by the x32 ABI, and use the 64-bit native structure layout for rusage on all architectures with new system calls that is otherwise compatible. A downside of this is that it requires a number of ugly hacks to deal with all the other fields of the structure also becoming 64 bit wide. Especially on big-endian architectures, we can't easily use the union trick from glibc. c) Change the definition of struct rusage to be independent of time_t. This is the easiest change, as it does not involve new system call entry points, but it requires the C library to convert between the kernel format of the structure and the user space definition. d) Add a new ABI variant of 'struct rusage' that corresponds to the current layout with 32-bit counters but 64-bit time_t. This would minimize the libc changes but require additional kernel code to handle a third binary layout on 64-bit kernels. I'm picking approach c) for its simplicity. As pointed out by reviewers, simply using the kernel structure in user space would not be POSIX compliant, but I have verified that none of the usual C libraries (glibc, musl, uclibc-ng, newlib) do that. Instead, they all provide their own definition of 'struct rusage' to applications in sys/resource.h. To be on the safe side, I'm only changing the definition inside of the kernel and for user space with an updated 'time_t'. All existing users will see the traditional layout that is compatible with what the C libraries export. A 32-bit application that includes linux/resource.h but uses an update C library with 64-bit time_t will now see the low-level kernel structure that corresponds to the getrusage() system call interface but that will be different from one defined in sys/resource.h for the getrusage library interface.

[PATCH] [v3] reiserfs: change j_timestamp type to time64_t

by Arnd Bergmann

This uses the deprecated time_t type but is write-only, and could be removed, but as Jeff explains, having a timestamp can be usefule for post-mortem analysis in crash dumps. In order to remove one of the last instances of time_t, this changes the type to time64_t, same as j_trans_start_time.

[PATCH 1/6] ext4: sysfs: print ext4_super_block fields as little-endian

by Arnd Bergmann

While working on extended rand for last_error/first_error timestamps, I noticed that the endianess is wrong, we access the little-endian fields in struct ext4_super_block as native-endian when we print them. This adds a special case in ext4_attr_show() and ext4_attr_store() to byteswap the superblock fields if needed. In older kernels, this code was part of super.c, it got moved to sysfs.c in linux-4.4.

Right, I've been a bit inconsistent here across file systems, I've done this in some other ones, using either a cast or a lower_32_bits() function call. Changed it as you suggested here now. Arnd

[PATCH 1/5] ceph: use timespec64 in for keepalive

by Arnd Bergmann

ceph_con_keepalive_expired() is the last user of timespec_add() and some of the last uses of ktime_get_real_ts(). Replacing this with timespec64 based interfaces lets us remove that deprecated API. I'm introducing new ceph_encode_timespec64()/ceph_decode_timespec64() here that take timespec64 structures and convert to/from ceph_timespec, which is defined to have an unsigned 32-bit tv_sec member. This extends the range of valid times to year 2106, avoiding the year 2038 overflow. The ceph file system portion still uses the old functions for inode timestamps, this will be done separately after the VFS layer is converted.

[PATCH 1/3] btrfs: use monotonic time for transaction handling

by Arnd Bergmann

get_seconds() is deprecated because of the overflow of 32-bit times, and it's not the best choice for measuring time intervals because it can go backwards or jump due to settimeofday() or leap seconds. This changes the transaction handling to instead use ktime_get_seconds(), which returns a CLOCK_MONOTONIC timestamp that has neither of those problems.

[PATCH 1/2] cifs: use timespec64 internally

by Arnd Bergmann

In cifs, the timestamps are stored in memory in the cifs_fattr structure, which uses the deprecated 'timespec' structure. Now that the VFS code has moved on to 'timespec64', the next step is to change over the fattr as well. This also makes 32-bit and 64-bit systems behave the same way, and no longer overflow the 32-bit time_t in year 2038.

[PATCH] bcache: stop using the deprecated get_seconds()

by Arnd Bergmann

bcache uses get_seconds() to read the current system time and store it in the superblock as well as in uuid_entry structures that are user visible. This changes over from the deprecated function to ktime_get_real_seconds(), which returns a 64-bit timestamp as it should. Unfortunately, the two structures are still limited to 32 bits, so this won't fix any real problems. Let's at least document that properly, in case we get an updated format in the future it can be fixed. Until then, we still have some time, and checking the tools at https://github.com/koverstreet/bcache-tools reveals no access to any of them.

[PATCH] ext2: use ktime_get_real_seconds for timestamps

by Arnd Bergmann

get_seconds() is deprecated because of the y2038 overflow, so users should migrate to 64-bit timestamps using ktime_get_real_seconds(). In ext2, the timestamps in the superblock and in the inode are all limited to 32-bit, and this won't get fixed, so let's just stop using the deprecated interface and keep truncating. All users of ext2 should migrate to ext4 before 2038 to prevent this from causing problems.

[PATCH 1/2] [v2] afs: stop using time_t for internal times

by Arnd Bergmann

afs uses 32-bit timestamps everywhere, but mixes signed and unsigned usage, which is a bit inconsistent. In particular on 32-bit machines, it currently uses unsigned timestamps (ranging from 1970 to 2106) for locally modified files, but signed timestamps (rand 1902 to 2038) when reading from a remote end. On 64-bit machines, we always interpret timestamps as unsigned here. This replaces the deprecated time_t with a new explicitly unsigned afs_time32_t to get a consistent interpretation of inode times according the the wire protocol definition. This avoids the y2038 overflow on 32-bit machines, extending the range to the end of the afs_time32_t in year 2106. On 64-bit machines, using the shorter type saves a few bytes for each afs_file_status and afs_volsync saves a few bytes over time_t or time64_t. Note that mtime_server and struct afs_volsync are not currently used in any meaningful way and could be removed completely.

[PATCH] [v2] cachefiles: avoid deprecated get_seconds()

by Arnd Bergmann

get_seconds() returns an unsigned long can overflow on some architectures and is deprecated because of that. In cachefs, we cast that number to a a 32-bit integer, which will overflow in year 2106 on all architectures. As confirmed by David Howells, the overflow probably isn't harmful in the end, since the timestamps are only used to make the file names unique, but they don't strictly have to be in monotonically increasing order since the files only exist in order to be deleted as quickly as possible. Moving to ktime_get_real_seconds() avoids the deprecated interface.

by Arnd Bergmann

In particular on 32-bit machines, it currently uses unsigned timestamps (ranging from 1970 to 2106) for locally modified files, but signed timestamps (rand 1902 to 2038) when reading from a remote end. On 64-bit machines, we always interpret timestamps as unsigned here. This replaces the deprecated time_t and get_seconds() interfaces with the modern time64_t and current_time() to locally store 64-bit timestamps, taking care to use unsigned interpretation of the raw values everywhere, which avoids the y2038 overflow and is consistent with the previous usage on 64-bit machines.

[PATCH] udf: convert inode stamps to timespec64

by Arnd Bergmann

The VFS structures are finally converted to always use 64-bit timestamps, and this file system can represent a long range of on-disk timestamps already, so now let's fit in the missing bits for udf.

[PATCH] sysvfs: use ktime_get_real_seconds() for superblock stamp

by Arnd Bergmann

get_seconds() is deprecated in favor of ktime_get_real_seconds(), which returns a 64-bit timestamp. In the SYSV file system, the superblock timestamp is only 32 bits wide, and it is used to check whether a file system is clean, so the best solution seems to be to force a wraparound and explicitly convert it to an unsigned 32-bit value. This is independent of the inode timestamps that are also 32-bit wide on disk and that come from current_time().

[PATCH] ufs: use ktime_get_real_seconds for sb and cg timestamps

by Arnd Bergmann

get_seconds() is deprecated because of the 32-bit overflow and will be removed. All callers in ufs also truncate to a 32-bit number, so nothing changes during the conversion, but this should be harmless as the superblock and cylinder group timestamps are not visible to user space, except for checking the fs-dirty state, wich works fine across the overflow. This moves the call to get_seconds() into a new inline function, with a comment explaining the constraints, while converting it to ktime_get_real_seconds().

[PATCH] shmem: use monotonic time for i_generation

by Arnd Bergmann

get_seconds() is deprecated because it will lead to a 32-bit overflow in 2038 or 2106. We don't need the i_generation to be strictly monotonic anyway, and other file systems like ext4 and xfs just use prandom_u32(), so let's use the same one here. If this is considered too slow, we could also use ktime_get_seconds() or ktime_get_real_seconds() to keep the previous behavior. Both of these return a time64_t and are not deprecated, but only return a unique value once per second, and are predictable.

[PATCH] ocfs2: dlmglue: clean up timestamp handling

by Arnd Bergmann

The handling of timestamps outside of the 1970..2038 range in the dlm glue is rather inconsistent: on 32-bit architectures, this has always wrapped around to negative timestamps in the 1902..1969 range, while on 64-bit kernels all timestamps are interpreted as positive 34 bit numbers in the 1970..2514 year range. Now that the VFS code handles 64-bit timestamps on all architectures, we can make the behavior more consistent here, and return the same result that we had on 64-bit already, making the file system y2038 safe in the process. Outside of dlmglue, it already uses 64-bit on-disk timestamps anway, so that part is fine. For consistency, I'm changing ocfs2_pack_timespec() to clamp anything outside of the supported range to the minimum and maximum values. This avoids a possible ambiguity of values before 1970 in particular, which used to be interpreted as times at the end of the 2514 range previously.

[PATCH] [net-next, v2] tcp: use monotonic timestamps for PAWS

by Arnd Bergmann

Using get_seconds() for timestamps is deprecated since it can lead to overflows on 32-bit systems. While the interface generally doesn't overflow until year 2106, the specific implementation of the TCP PAWS algorithm breaks in 2038 when the intermediate signed 32-bit timestamps overflow. A related problem is that the local timestamps in CLOCK_REALTIME form lead to unexpected behavior when settimeofday is called to set the system clock backwards or forwards by more than 24 days. While the first problem could be solved by using an overflow-safe method of comparing the timestamps, a nicer solution is to use a monotonic clocksource with ktime_get_seconds() that simply doesn't overflow (at least not until 136 years after boot) and that doesn't change during settimeofday(). To make 32-bit and 64-bit architectures behave the same way here, and also save a few bytes in the tcp_options_received structure, I'm changing the type to a 32-bit integer, which is now safe on all architectures. Finally, the ts_recent_stamp field also (confusingly) gets used to store a jiffies value in tcp_synq_overflow()/tcp_synq_no_recent_overflow(). This is currently safe, but changing the type to 32-bit requires some small changes there to keep it working.

[PATCH] coda: stop using 'struct timespec' in user API

by Arnd Bergmann

We exchange file timestamps with user space using psdev device read/write operations with a fixed but architecture specific binary layout. On 32-bit systems, this uses a 'timespec' structure that is defined by the C library to contain two 32-bit values for seconds and nanoseconds. As we get ready for the year 2038 overflow of the 32-bit signed seconds, the kernel now uses 64-bit timestamps internally, and user space will do the same change by changing the 'timespec' definition in the future. Unfortunately, this breaks the layout of the coda_vattr structure, so we need to redefine that in terms of something that does not change. I'm introducing a new 'struct vtimespec' structure here that keeps the existing layout, and the same change has to be done in the coda user space copy of linux/coda.h before anyone can use that on a 32-bit architecture with 64-bit time_t. An open question is what should happen to actual times past y2038, as they are now truncated to the last valid date when sent to user space, and interpreted as pre-1970 times when a timestamp with the MSB set is read back into the kernel. Alternatively, we could change the new timespec64_to_coda()/coda_to_timespec64() functions to use a different interpretation and extend the available range further to the future by disallowing past timestamps. This would require more changes in the user space side though.

[PATCH] jfs: use time64_t for otime

by Arnd Bergmann

The file creation time in the inode uses time_t which is defined differently on 32-bit and 64-bit architectures and deprecated. The representation in the inode uses an unsigned 32-bit number, but this gets wrapped around after year 2038 when assigned to a time_t. This changes the type to time64_t, so we can support the full range of timestamps between 1970 and 2106 on 32-bit systems like we do on 64-bit systems already, and matching what we do for the atime/ctime/mtime stamps since the introduction of 64-bit timestamps in VFS. Note: the otime stamp is not actually used anywhere at the moment in the kernel, it is just set when writing a file, so none of this really makes a difference unless we implement setting the btime field in the getattr() callback.

[PATCH] fat: propagate 64-bit inode timestamps

by Arnd Bergmann

Now that we pass down 64-bit timestamps from VFS, we just need to convert that correctly into on-disk timestamps. To make that work correctly, this changes the last use of time_to_tm() in the kernel to time64_to_tm(), which also lets use remove that deprecated interfaces. Similarly, the time_t use in fat_time_fat2unix() truncates the timestamp on the way in, which can be avoided by using types that are wide enough to hold the intermediate values during the conversion.

[PATCH] hpfs: extend gmt_to_local() conversion to 64-bit times

by Arnd Bergmann

The VFS timestamps are all 64-bit now, the only missing piece for hpfs is the internal conversion function. One interesting bit about hpfs is that it can already deal with moving the 136 year window of its timestamps to support a much wider range than other file systems with 32-bit timestamps. It also treats the timestamps as 'unsigned' on 64-bit architectures (but signed on 32-bit, because time_t always around to negative numbers in 2038). Changing the conversion to use time64_t makes 32-bit architectures behave the same way as 64-bit. For completeness, this also adds a clamp_t call for each conversion, so we don't wrap the timestamps but instead stay within the [0..U32_MAX] range of the on-disk timestamps.

[PATCH 1/3] powerpc: mac: fix rtc read functions

by Arnd Bergmann

As Mathieu pointed out, my conversion to time64_t was incorrect and resulted in negative times to be read from the RTC. The problem is that during the conversion from a byte array to a time64_t, the 'unsigned char' variable holding the top byte gets turned into a negative signed 32-bit integer before being assigned to the 64-bit variable for any times after 1972. This changes the logic to cast to an unsigned 32-bit number first for the Macintosh time and then convert that to the Unix time, which then gives us a time in the documented 1904..2040 year range. I decided not to use the longer 1970..2106 range that other drivers use, for consistency with the literal interpretation of the register, but that could be easily changed if we decide we want to support any Mac after 2040. Just to be on the safe side, I'm also adding a WARN_ON that will trigger if either the year 2040 has come and is observed by this driver, or we run into an RTC that got set back to a pre-1970 date for some reason (the two are indistinguishable). The same code exists in arch/m68k/ and is patched in an identical way now in a separate patch.

[PATCH net-next 1/3] xfrm: use time64_t for in-kernel timestamps

by Arnd Bergmann

The lifetime managment uses '__u64' timestamps on the user space interface, but 'unsigned long' for reading the current time in the kernel with get_seconds(). While this is probably safe beyond y2038, it will still overflow in 2106, and the get_seconds() call is deprecated because fo that. This changes the xfrm time handling to use time64_t consistently, along with reading the time using the safer ktime_get_real_seconds(). It still suffers from problems that can happen from a concurrent settimeofday() call or (to a lesser degree) a leap second update, but since the time stamps are part of the user API, there is nothing we can do to prevent that.

[PATCH] firewire: ohci: stop using get_seconds() for BUS_TIME

by Arnd Bergmann

The ohci driver uses the get_seconds() function to implement the 32-bit CSR_BUS_TIME register. This was added in 2010 commit a48777e03ad5 ("firewire: add CSR BUS_TIME support"). As get_seconds() returns a 32-bit value (on 32-bit architectures), it seems like a good fit for that register, but it is also deprecated because of the y2038/y2106 overflow problem, and should be replaced throughout the kernel with either ktime_get_real_seconds() or ktime_get_seconds(). I'm using the latter here, which uses monotonic time. This has the advantage of behaving better during concurrent settimeofday() updates or leap second adjustments and won't overflow a 32-bit integer, but the downside of using CLOCK_MONOTONIC instead of CLOCK_REALTIME is that the observed values are not related to external clocks. If we instead need UTC but can live with clock jumps or overflows, then we should use ktime_get_real_seconds() instead, retaining the existing behavior.

[PATCH net-next] nfp: avoid using getnstimeofday64()

by Arnd Bergmann

getnstimeofday64 is deprecated in favor of the ktime_get() family of functions. The direct replacement would be ktime_get_real_ts64(), but I'm picking the basic ktime_get() instead: - using a ktime_t simplifies the code compared to timespec64 - using monotonic time instead of real time avoids issues caused by a concurrent settimeofday() or during a leap second adjustment.

[PATCH] ipmi: Change to ktime_get_ts64()

by Arnd Bergmann

getnstimeofday64() is deprecated because of the inconsistent naming, it is only a wrapper around ktime_get_real_ts64() now, which could be used as a direct replacement. However, it is generally better to use CLOCK_MONOTONIC timestamps where possible, to avoid glitches with a concurrent settimeofday() or leap second. The uses in ipmi are either for debugging prints or for comparing against a prior timestamp, so using a monotonic ktime_get_ts64() is probably best here.

[PATCH] efi: cper: avoid using get_seconds()

by Arnd Bergmann

get_seconds() is deprecated because of the 32-bit time overflow in y2038/y2106 on 32-bit architectures. The way it is used in cper_next_record_id() causes an overflow in 2106 when unsigned UTC seconds overflow, even on 64-bit architectures. This starts using ktime_get_real_seconds() to give us more than 32 bits of timestamp on all architectures, and then changes the algorithm to use 39 bits for the timestamp after the y2038 wrap date, plus an always-1 bit at the top. This gives us another 127 epochs of 136 years, with strictly monotonically increasing sequence numbers across boots. This is almost certainly overkill, but seems better than just extending the deadline from 2038 to 2106.

[PATCH] firewire: use 64-bit time_t based interfaces

by Arnd Bergmann

32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2 ioctl, we already support 64-bit timestamps, but the implementation still uses timespec. This changes the code to use timespec64 instead with the appropriate accessor functions.

[PATCH] snic: fix printing time intervals

by Arnd Bergmann

We don't want to use 'struct timespec' because of the y2038 overflow problem. The overflow is not actually an issue here, but it's easy to replace with 'timespec64' for consistency. However, it's worth pointing out that nanosecond values have nine digits, not eight or ten, so I'm fixing the format strings accordingly as well.

[PATCH] sysinfo: remove get_monotonic_boottime()

[PATCH] staging: rtsx: remove rtsx_trace() and related code

by Arnd Bergmann

The driver has rather excessive amount of tracing code, which would be better done using ftrace. This is obviously not a main feature of the driver, and it should work just as well without it. Removing it saves over 1300 lines of code and likely makes the driver a bit faster by avoiding lots of calls into the timekeeping code. I came across this while cleaning up the last users of the deprecated getnstimeofday64() function, of which there is one in the now-removed get_current_time() function of the rtsx driver that was only used for tracing.

[PATCH] misc: mic: fix passing the current time

by Arnd Bergmann

I noticed that the mic driver passes a 'struct timespec64' as part of a message into an attached device, where it is used to set the current system time. This won't actually work if one of the two sides runs a 32-bit kernel and the other runs a 64-bit kernel, since the structure layout is different between the two. I found this while replacing calls to the deprecated do_settimeofday64() interface with the modern ktime_get_real_ts() variant, but it seems appropriate to address both at the same time here. To make sure we have a sane structure, let's define our own structure using the layout of the 64-bit kernel.

[PATCH] x86: mce: always use 64-bit timestamps

by Arnd Bergmann

The machine check timestamp uses get_seconds(), which returns an 'unsigned long' number that might overflow on 32-bit architectures (in the distant future) and is therefore deprecated. The normal replacement would be ktime_get_real_seconds(), but that needs to use a sequence lock that might cause a deadlock if the mce happens at just the wrong moment. The __ktime_get_real_seconds() skips that lock and is safer here, but has a miniscule risk of returning the wrong time when we read it on a 32-bit architecture at the same time as updating the epoch, i.e. from before y2106 overflow time to after, or vice versa. This seems to be an acceptable risk in this particular case, and is the same thing we do in kdb.

[PATCH] s390: hypfs: use ktime_get_seconds() instead of get_seconds()

by Arnd Bergmann

time_t and get_seconds() are deprecated because they will overflow on 32-bit architectures in the future. This is not a problem on 64-bit s390, but we should use proper interfaces anyway. Besides moving to the time64_t based interface, the CLOCK_MONOTONIC based ktime_get_seconds() is preferred for kernel internal timekeeping because it does not behave in unexpected ways during leap second changes or settimeofday() calls.

[PATCH 0/3] time: Add y2038 safe struct __kernel_itimerspec

by Deepa Dinamani

The series aims at adding a new y2038-safe struct __kernel_itimerspec. This is intended to replace the struct itimerspec at ABI level. The series is a continuation of efforts to convert all syscalls with time_t or time_t-derived structures to be y2038-safe. Arnd, maybe this series can go along with the rest of syscalls that you have in your y2038 tree?

[GIT PULL] vfs/y2038: inode timestamps conversion to timespec64

by Arnd Bergmann

The following changes since commit 93b7f7ad2018d2037559b1d0892417864c78b371: skip LAYOUTRETURN if layout is invalid (2018-06-12 08:48:04 -0400) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git tags/vfs-timespec64 for you to fetch changes up to e264abeaf9daa3cde9aed8013a6f82b0370425e5: pstore: Remove bogus format string definition (2018-06-14 14:57:24 +0200) ---------------------------------------------------------------- vfs/y2038: inode timestamps conversion to timespec64 This is a late set of changes from Deepa Dinamani doing an automated treewide conversion of the inode and iattr structures from 'timespec' to 'timespec64', to push the conversion from the VFS layer into the individual file systems. There were no conflicts between this and the contents of linux-next until just before the merge window, when we saw multiple problems: - A minor conflict with my own y2038 fixes, which I could address by adding another patch on top here. - One semantic conflict with late changes to the NFS tree. I addressed this by merging Deepa's original branch on top of the changes that now got merged into mainline and making sure the merge commit includes the necessary changes as produced by coccinelle. - A trivial conflict against the removal of staging/lustre. - Multiple conflicts against the VFS changes in the overlayfs tree. These are still part of linux-next, but apparently this is no longer intended for 4.18 [1], so I am ignoring that part. As Deepa writes: The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions. Thomas Gleixner adds: I think there is no point to drag that out for the next merge window. The whole thing needs to be done in one go for the core changes which means that you're going to play that catchup game forever. Let's get over with it towards the end of the merge window.

vfs_timespec64 merge into v4.18?

by Arnd Bergmann

Hi everyone, As I discussed with Thomas on IRC, I'd still like to try to get Deepa's series merged to have 64-bit inode timestamps in VFS, as a prerequisite to fixing the individual file systems for y2038 as the next step. The orignal tree that I've been testing with is in https://github.com/deepa-hub/vfs vfs_timespec64 (see description at [1] Unfortunately this was never in linux-next so far, so it's definitely against our normal rules, and if there are any objections (or new issues getting found), then we should defer it another merge window. Until very recently, the branch worked fine with both linux-next and 4.17-rc, but with some last minute changes to the NFS and Overlayfs trees, it gained some nasty conflicts. I've merged Trond's NFS branch and Miklos' Overlayfs branches into it, fixed up those conflicts and now uploaded it to my tree at git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git Obviously this will break if either of them rebases their trees once more, in which case I assume Stephen will drop my branch from linux-next. Once those two are merged into mainline and nothing unexpected has come up from linux-next testing, we could either send a pull request to Linus for the merged branch, or regenerate the flag-day patch in it using coccinelle, which should result in identical contents.

[PATCH 1/5] powerpc: always enable RTC_LIB

by Arnd Bergmann

In order to use the rtc_tm_to_time64() and rtc_time64_to_tm() helper functions in later patches, we have to ensure that CONFIG_RTC_LIB is always built-in. Note that this symbol only controls a couple of helper functions, not the actual RTC subsystem, which remains optional and is enabled with CONFIG_RTC_CLASS.

[GIT PULL] Transition vfs to 64-bit timestamps

by Deepa Dinamani

Hi Thomas, This is a pull request for the series that I sent earlier. The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The flag patch applies cleanly. I've not seen the timestamps update logic change often. The series applies cleanly on 4.17-rc6 and linux-next tip (top commit: next-20180517). I'm not sure how to merge this kind of a series with a flag patch. We are targeting 4.18 for this. Let me know if you have other suggestions. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. I've tried to keep the conversions with the script simple, to aid in the reviews. I've kept all the internal filesystem data structures and function signatures the same. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions. -- Changes from v1: * Fix the pointer bug in the udf patch. * Include Kees's patch for pstore. * Fix hostfs regression found by kbuild bot.

[PATCH] pstore: Remove bogus format string definition

by Arnd Bergmann

The pstore conversion to timespec64 introduces its own method of passing seconds into sscanf() and sprintf() type functions to work around the timespec64 definition on 64-bit systems that redefine it to 'timespec'. That hack is now finally getting removed, but that means we get a (harmless) warning once both patches are merged: fs/pstore/ram.c: In function 'ramoops_read_kmsg_hdr': fs/pstore/ram.c:39:29: error: format '%ld' expects argument of type 'long int *', but argument 3 has type 'time64_t *' {aka 'long long int *'} [-Werror=format=] #define RAMOOPS_KERNMSG_HDR "====" ^~~~~~ fs/pstore/ram.c:167:21: note: in expansion of macro 'RAMOOPS_KERNMSG_HDR' This removes the pstore specific workaround and uses the same method that we have in place for all other functions that print a timespec64. Related to this, I found that the kasprintf() output contains an incorrect nanosecond values for any number starting with zeroes, and I adapt the format string accordingly.

[PATCH 1/3] rtc: vr41xx: remove mktime usage

by Arnd Bergmann

This driver uses mktime() and rtc_time_to_tm() to convert between time values. This works fine on 64-bit kernels over the whole supported range, and the vr41xx chip is a 64-bit MIPS implementation, but it is inconsistent because it doesn't do the same thing on 32-bit kernels that overflow in 2106 or 2038. Changing it to use mktime64/rtc_time64_to_tm() should have no visible impact on vr41xx but gets us closer to removing the 32-bit interfaces.

[PATCH 0/6] Transition vfs to 64-bit timestamps

by Deepa Dinamani

The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. I've tried to keep the conversions with the script simple, to aid in the reviews. I've kept all the internal filesystem data structures and function signatures the same. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions.

[PATCH] [v3] x86: Convert x86_platform_ops to timespec64

by Arnd Bergmann

The x86 platform operations are fairly isolated, so we can change them from using timespec to timespec64. I checked that All the users and callers are safe, and there is only one critical function that is broken beyond 2106: pvclock_read_wallclock() uses a 32-bit number of seconds since the epoch to communicate the boot time between host and guest in a virtual environment. This will work until 2106, but we should ideally find a replacement anyway. I've added a comment about it there. Reviewed-by: Boris Ostrovsky <boris.ostrovsky(a)oracle.com> Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- v2 changes: - move comment block (Boris) - remove unnecessary type cast (Boris) - fix format string (0day bot) - fix include order (0day bot) v3 changes: - add jailhouse specific change - avoid include file header by relying on another patch ("timekeeping: Remove timespec64 hack") Not sure how we want to merge this (assuming the last modification worked, this has seen little testing). The "timekeeping: Remove timespec64 hack" patch should go through the timekeeping branch in tip, while this one is for x86. I assume the linux-tip maintainers can come up with a plan. --- arch/x86/include/asm/intel_mid_vrtc.h | 4 ++-- arch/x86/include/asm/mc146818rtc.h | 4 ++-- arch/x86/include/asm/pvclock.h | 2 +- arch/x86/include/asm/x86_init.h | 6 +++--- arch/x86/kernel/jailhouse.c | 2 +- arch/x86/kernel/kvmclock.c | 4 ++-- arch/x86/kernel/pvclock.c | 15 +++++++++++---- arch/x86/kernel/rtc.c | 10 +++++----- arch/x86/platform/intel-mid/intel_mid_vrtc.c | 12 ++++++------ arch/x86/xen/time.c | 10 +++++----- 10 files changed, 38 insertions(+), 31 deletions(-) diff --git a/arch/x86/include/asm/intel_mid_vrtc.h b/arch/x86/include/asm/intel_mid_vrtc.h index 35555016b1be..0b44b1abe4d9 100644 --- a/arch/x86/include/asm/intel_mid_vrtc.h +++ b/arch/x86/include/asm/intel_mid_vrtc.h @@ -4,7 +4,7 @@ extern unsigned char vrtc_cmos_read(unsigned char reg); extern void vrtc_cmos_write(unsigned char val, unsigned char reg); -extern void vrtc_get_time(struct timespec *now); -extern int vrtc_set_mmss(const struct timespec *now); +extern void vrtc_get_time(struct timespec64 *now); +extern int vrtc_set_mmss(const struct timespec64 *now); #endif diff --git a/arch/x86/include/asm/mc146818rtc.h b/arch/x86/include/asm/mc146818rtc.h index 1775a32f7ea6..97198001e567 100644 --- a/arch/x86/include/asm/mc146818rtc.h +++ b/arch/x86/include/asm/mc146818rtc.h @@ -95,8 +95,8 @@ static inline unsigned char current_lock_cmos_reg(void) unsigned char rtc_cmos_read(unsigned char addr); void rtc_cmos_write(unsigned char val, unsigned char addr); -extern int mach_set_rtc_mmss(const struct timespec *now); -extern void mach_get_cmos_time(struct timespec *now); +extern int mach_set_rtc_mmss(const struct timespec64 *now); +extern void mach_get_cmos_time(struct timespec64 *now); #define RTC_IRQ 8 diff --git a/arch/x86/include/asm/pvclock.h b/arch/x86/include/asm/pvclock.h index a7471dcd2205..b6033680d458 100644 --- a/arch/x86/include/asm/pvclock.h +++ b/arch/x86/include/asm/pvclock.h @@ -12,7 +12,7 @@ void pvclock_set_flags(u8 flags); unsigned long pvclock_tsc_khz(struct pvclock_vcpu_time_info *src); void pvclock_read_wallclock(struct pvclock_wall_clock *wall, struct pvclock_vcpu_time_info *vcpu, - struct timespec *ts); + struct timespec64 *ts); void pvclock_resume(void); void pvclock_touch_watchdogs(void); diff --git a/arch/x86/include/asm/x86_init.h b/arch/x86/include/asm/x86_init.h index ce8b4da07e35..2d27236c16a3 100644 --- a/arch/x86/include/asm/x86_init.h +++ b/arch/x86/include/asm/x86_init.h @@ -170,7 +170,7 @@ struct x86_cpuinit_ops { void (*fixup_cpu_id)(struct cpuinfo_x86 *c, int node); }; -struct timespec; +struct timespec64; /** * struct x86_legacy_devices - legacy x86 devices @@ -264,8 +264,8 @@ struct x86_hyper_runtime { struct x86_platform_ops { unsigned long (*calibrate_cpu)(void); unsigned long (*calibrate_tsc)(void); - void (*get_wallclock)(struct timespec *ts); - int (*set_wallclock)(const struct timespec *ts); + void (*get_wallclock)(struct timespec64 *ts); + int (*set_wallclock)(const struct timespec64 *ts); void (*iommu_shutdown)(void); bool (*is_untracked_pat_range)(u64 start, u64 end); void (*nmi_init)(void); diff --git a/arch/x86/kernel/jailhouse.c b/arch/x86/kernel/jailhouse.c index fa183a131edc..a0b05bf185ac 100644 --- a/arch/x86/kernel/jailhouse.c +++ b/arch/x86/kernel/jailhouse.c @@ -37,7 +37,7 @@ static uint32_t __init jailhouse_detect(void) return jailhouse_cpuid_base(); } -static void jailhouse_get_wallclock(struct timespec *now) +static void jailhouse_get_wallclock(struct timespec64 *now) { memset(now, 0, sizeof(*now)); } diff --git a/arch/x86/kernel/kvmclock.c b/arch/x86/kernel/kvmclock.c index 8b26c9e01cc4..bf8d1eb7fca3 100644 --- a/arch/x86/kernel/kvmclock.c +++ b/arch/x86/kernel/kvmclock.c @@ -53,7 +53,7 @@ static struct pvclock_wall_clock *wall_clock; * have elapsed since the hypervisor wrote the data.

[PATCH 0/5] timekeeping: API cleanup and extensions

by Arnd Bergmann

Hi Thomas, I've had these patches for a while but never got around to submitting them. I recently rebased them after the boot time removal and now again after the revert. I'd like to see these go into v4.18 as a preparation for a last set of driver conversions to y2038-safe interfaces that I've held off for now since the interfaces were suboptimal. The problems solved by this series are: - aliasing timespec to timespec64 is a little erorr-prone, and in particular requires ugly casts to print a tv_sec field using the same format string across architectures - naming is inconsistent, and while converting from the deprecated time_t to something else, I'd like to also convert to a ktime_get_*() API for consistency - drivers that use current_kernel_time() today often care about the call being fast but don't care about it being CLOCK_REALTIME based, so they are better off being changed to a CLOCK_MONOTONIC or CLOCK_BOOTTIME based accessor to avoid issues with time going backwards. Arnd Arnd Bergmann (5): timekeeping: Remove timespec64 hack timekeeping: Clean up ktime_get_real_ts64 timekeeping: Standardize on ktime_get_*() naming timekeeping: Add ktime_get_coarse_with_offset timekeeping: Add more coarse clocktai/boottime interfaces include/linux/time32.h | 18 ++------- include/linux/time64.h | 7 ---- include/linux/timekeeping.h | 91 ++++++++++++++++++++++++++++++++++++------- include/linux/timekeeping32.h | 70 ++++++--------------------------- kernel/time/time.c | 2 - kernel/time/timekeeping.c | 73 ++++++++++++++++------------------ 6 files changed, 124 insertions(+), 137 deletions(-) -- 2.9.0

[PATCH 0/4] ALSA: Fix year 2038 issue for sound subsystem, alternative

by Arnd Bergmann

I've tried the suggestion from Jaroslaw, doing a minimal change to the UAPI headers to keep the existing binary interface. As he predicted, this is a much simpler set of kernel changes, but we will pay for that with added complexity in alsa-lib. The first two patches in this series are taken from Baolin's patch set, with a small bugfix folded in to avoid a compile-time regression. The other two patches are to redefine the UAPI and to deprecate the support for CLOCK_REALTIME time stamps, which we can no longer allow with user space that we expect to survive beyond 2038. Overall, I'd still be happier with Baolin's approach since it allows us to keep compatiblity with CLOCK_REALTIME users and requires fewer changes in user space, but this would work as well.

[PATCH 00/17] y2038: system calls, part 3

by Arnd Bergmann

After the first timekeeping series from Deepa (merged into -tip now) and my follow-up for IPC system calls, this is a third set of system call conversions following the same principle. Most of the changes are straightforward, so I'm grouping them into a larger series even though the system calls are mostly unrelated to one another. After this series, the remaining calls that need to be changed are getrusage()/waitid(), pselect6/ppoll(), timer{,fd}_{get,set}time() and getitimer()/setitimer(). Those will be sent separately, once they are matured enough. To put the changes into perspective, a list of all system calls that require changes is available in a spreadsheet[1] and I have made another experimental patch that changes over x86[2] and arm[3] to actually use them.

[GIT PULL, PATCH v4 00/16] y2038: IPC system call conversion

by Arnd Bergmann

Hi Thomas, This is a small update to last week's patch series, I hope I have worked out all the remaining issues now. If nothing else comes up, please pull into tip for 4.18. The commits are based on top of what you already pulled into timers/core, so you can either add these to the same branch or to a different one. I'll be away for three weeks starting on Sunday, so if new issues get found, I won't be able to address them until I get back home. I'll post another set of simpler syscall patches for review after this, and there is at last a fourth set of those that are not ready yet, but is available for preview at [3], which also contains unrelated y2038 patches for random subsystems. Arnd ---------------------------------------------------------------- The following changes since commit 01909974b41036a6a8d3907c66cc7b41c9a73da9: time: Change nanosleep to safe __kernel_* types (2018-04-19 13:32:03 +0200) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git y2038-ipc for you to fetch changes up to 5dc0b1529d21b54aad4098874e334a52027fd16d: y2038: ipc: Redirect ipc(SEMTIMEDOP, ...) to compat_ksys_semtimedop (2018-04-20 16:20:30 +0200) ---------------------------------------------------------------- y2038: IPC system call conversion This is a follow-up to Deepa's work on the timekeeping system calls, providing a y2038-safe syscall API for SYSVIPC. It uses a combination of two strategies: For sys_msgctl, sys_semctl and sys_shmctl, I do not introduce a completely new set of replacement system calls, but instead extend the existing ones to return data in the reserved fields of the normal data structure. This should be completely transparent to any existing user space, and only after the 32-bit time_t wraps, it will make a difference in the returned data. libc implementations will consequently have to provide their own data structures when they move to 64-bit time_t, and convert the structures in user space from the ones returned by the kernel. In contrast, mq_timedsend, mq_timedreceive and and semtimedop all do need to change because having a libc redefine the timespec type breaks the ABI, so with this series there will be two separate entry points for 32-bit architectures. There are three cases here: - little-endian architectures (except powerpc and mips) can use the normal layout and just cast the data structure to the user space type that contains 64-bit numbers. - parisc and sparc can do the same thing with big-endian user space - little-endian powerpc and most big-endian architectures have to flip the upper and lower 32-bit halves of the time_t value in memory, but can otherwise keep using the normal layout - mips and big-endian xtensa need to be more careful because they are not consistent in their definitions, and they have to provide custom libc implementations for the system calls to use 64-bit time_t. ---------------------------------------------------------------- Changes to v3: - reworked x86 portion after discovering an old bug, submitted a fix for that separately. - use consistent types in asm-generic based on feedback from Jeffrey Walton Changes to v2: - added patches for mq_timedsend, mq_timedreceive and and semtimedop system calls - add asm-generic/compat.h changes to prepare for actually using those on 32-bit. - fix 'make headers_install' as reported by Heiko Carstens - fix MIPS build as reported by build bot - Cc everyone on all patches as originally intended, not just on the cover letter. Changes to v1 [1]: - Rebased to the latest kernel (4.17-rc) - Dropped changes for removed architectures - Simplified the IPC code changes, based on prior work from both Deepa and Eric - Fixed a few bugs that I found during rebasing, in parcular the sparc version was incorrect.

y2038 kernel status update

I've sent out new patches recently but will be on vacation for the next few weeks, so here's a quick update on where we are today with recent changes and work in progress: - A large number of small driver fixes got merged into linux-4.16. Many of these were old patches I had done a while ago but that had not made it in yet. There are a few dozen more of these coming, but those have some dependency. - Deepa Dinamani has done a lot of the groundwork for the system call conversion. Her latest patch series that got merged now finally adds new system call entry points for timekeeping related syscalls. They are not wired up yet, but now we have a template for the remaining ones, and we have sorted out the header file dependencies. - I just sent a pull request for a second chunk of system calls: The sysvipc semtimedop, semctl/shmctl/msgctl and mq_timedsend/mq_timedreceive calls. I have more patches for most of the remaining calls, and they should be simpler (this one was rather tricky). A full list can be found in a spreadsheet I made[2]. - Baolin Wang has worked on RTC related issues and most recently posted a series to convert the user space ABI for ALSA. This is currently under discussion. - The most complicated remaining part is the conversion of the VFS layer. Deepa is getting a new series for this ready after having done some groundwork over the past years. The current idea is to have a flag-day patch using coccinelle to change the inode, iattr and kstat structures over at the same time. Many file systems will require further changes after that, but those can be done individually through their respective maintainers. - Firoz Khan has started looking at the system call entry points in the architectures. We want to add the new system calls to all 32-bit architectures at once, in order to have a baseline release that C libraries can rely on for implementing 64-bit time_t on all architectures. Even after the architecture removal series, we still have over a dozen different syscall tables and each one is laid out slightly differently, which makes it hard to change. To improve this, Firoz is preparing a series that changes all architectures to use a common table format as used by x86, arm and s390 today. - I have collected all those patches in a git tree [1] for testing. This currently has updated system call entry points for 32-bit ARM and x86, but no others so far. The system call numbers *will* change before it gets merged, so be careful when building user space based on this, but it should be a starting point for testing. I definitely expect this to contain bugs still, especially to the end of the series, but the start of it should be fairly solid. Some patches are marked as work-in-progress or don't contain a proper changelog text. Those will still get reworked before a first version is posted to the mainling lists. - There are two notable areas not included in that tree today: v4l and socket timestamps. I've had patches for both in the past but they need to be reworked.

[PATCH] m68k: use read_persistent_clock64 consistently

by Arnd Bergmann

We have two ways of getting the current time from a platform at boot or during suspend: either using read_persistent_clock() or the rtc class operation. We never need both, so I'm hiding the read_persistent_clock variant when the generic RTC is enabled. Since read_persistent_clock() and mktime() are deprecated because of the y2038 overflow of time_t, we should use the time64_t based replacements here. Finally, the dependency on CONFIG_ARCH_USES_GETTIMEOFFSET looks completely bogus in this case, so let's remove that. It was added in commit b13b3f51ff7b ("m68k: fix inclusion of arch_gettimeoffset for non-MMU 68k classic CPU types") to deal with arch_gettimeoffset(), which has since been removed from this file and is unrelated to the RTC functions. The rtc accessors are only used by classic machines, while coldfire uses proper RTC drivers, so we can put the old ifdef back around both functions.

[PATCH v3 00/17] y2038: Convert IPC syscalls

by Arnd Bergmann

This is an update of a series I posted a long time ago [1], updating the IPC subsystem to pass down 64-bit time stamps to user space. In particular, for sys_msgctl, sys_semctl and sys_shmctl, I do not introduce a completely new set of replacement system calls, but instead extend the existing ones to return data in the reserved fields of the normal data structure. This should be completely transparent to any existing user space, and only after the 32-bit time_t wraps, it will make a difference in the returned data. libc implementations will consequently have to provide their own data structures when they move to 64-bit time_t, and convert the structures in user space from the ones returned by the kernel. In contrast, mq_timedsend, mq_timedreceive and and semtimedop all do need to change because having a libc redefine the timespec type breaks the ABI, so with this series, there will be two separate entry points for 32-bit architectures. There are three cases here: - little-endian architectures (except powerpc and mips) can use the normal layout and just cast the data structure to the user space type that contains 64-bit numbers. - parisc and sparc can do the same thing with big-endian user space - little-endian powerpc and most big-endian architectures have to flip the upper and lower 32-bit halves of the time_t value in memory, but can otherwise keep using the normal layout - mips and big-endian xtensa need to be more careful because they are not consistent in their definitions, and they have to provide custom libc implementations for the system calls to use 64-bit time_t. Changes to v2 [2]: - added patches for mq_timedsend, mq_timedreceive and and semtimedop system calls - add asm-generic/compat.h changes to prepare for actually using those on 32-bit. - fix 'make headers_install' as reported by Heiko Carstens - fix MIPS build as reported by build bot - Cc everyone on all patches as originally intended, not just on the cover letter. Changes to v1 [1]: - Rebased to the latest kernel (4.17-rc) - Dropped changes for removed architectures - Simplified the IPC code changes, based on prior work from both Deepa and Eric - Fixed a few bugs that I found during rebasing, in parcular the sparc version was incorrect. I haven't seen any objections to v1 and will send a pull request to Thomas Gleixner after Deepa's first patches are all merged there. There are a few more patches in my tree [3] now, I'm still testing those and should be able to send the next batch next week.

[PATCH v2 00/13] y2038: convert IPC syscalls

by Arnd Bergmann

This is an update of a series I posted a long time ago [1], updating the IPC subsystem to pass down 64-bit time stamps to user space. In particular, for sys_msgctl, sys_semctl and sys_shmctl, I do not introduce a completely new set of replacement system calls, but instead extend the existing ones to return data in the reserved fields of the normal data structure. This should be completely transparent to any existing user space, and only after the 32-bit time_t wraps, it will make a difference in the returned data. libc implementations will consequently have to provide their own data structures when they move to 64-bit time_t, and convert the structures in user space from the ones returned by the kernel. There are three cases here: - little-endian architectures (except powerpc and mips) can use the normal layout and just cast the data structure to the user space type that contains 64-bit numbers. - parisc and sparc can do the same thing with big-endian user space - little-endian powerpc and most big-endian architectures have to flip the upper and lower 32-bit halves of the time_t value in memory, but can otherwise keep using the normal layout - mips and big-endian xtensa need to be more careful because they are not consistent in their definitions, and they have to provide custom libc implementations for the system calls to use 64-bit time_t. Changes to the previous version include - Rebased to the latest kernel (4.17-rc) - Dropped changes for removed architectures - Simplified the IPC code changes, based on prior work from both Deepa and Eric - Fixed a few bugs that I found during rebasing, in parcular the sparc version was incorrect. If everyone agrees with the series, I'd like to have it merged through the tip tree once Deepa's earlier syscall series in there (I have both in my y2038 tree [2]).

[PATCH] sparc: compat: allow including asm/compat.h for 32-bit

by Arnd Bergmann

We have several files on sparc that include linux/compat.h and expect asm/compat.h not to be included, otherwise we get a build failure. Since we need to include asm/compat.h for compat time_t handling on all 32-bit architectures now, this hides some portions of asm/compat.h in order to let the rest of the file get included. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- arch/sparc/include/asm/compat.h | 4 ++++ 1 file changed, 4 insertions(+) This is the fix for the y2038 syscall series that missed the 4.17 merge window. I've now spent two more days doing extra build testing on all 64-bit archtectures building with and without CONFIG_COMPAT, as well as without CONFIG_64BIT. I did not run into any additional build failures after this patch, so my plan is to pick that up into my y2038 tree after -rc1 and send Thomas a pull request a few days later for inclusion in linux-4.18. diff --git a/arch/sparc/include/asm/compat.h b/arch/sparc/include/asm/compat.h index 161aeacbc9ad..4eb51d2dae98 100644 --- a/arch/sparc/include/asm/compat.h +++ b/arch/sparc/include/asm/compat.h @@ -157,6 +157,7 @@ static inline compat_uptr_t ptr_to_compat(void __user *uptr) return (u32)(unsigned long)uptr; } +#ifdef CONFIG_COMPAT static inline void __user *arch_compat_alloc_user_space(long len) { struct pt_regs *regs = current_thread_info()->kregs; @@ -173,6 +174,7 @@ static inline void __user *arch_compat_alloc_user_space(long len) return (void __user *) usp; } +#endif struct compat_ipc64_perm { compat_key_t key; @@ -232,6 +234,7 @@ struct compat_shmid64_ds { unsigned int __unused2; }; +#ifdef CONFIG_COMPAT static inline int is_compat_task(void) { return test_thread_flag(TIF_32BIT); @@ -243,5 +246,6 @@ static inline bool in_compat_syscall(void) return pt_regs_trap_type(current_pt_regs()) == 0x110; } #define in_compat_syscall in_compat_syscall +#endif #endif /* _ASM_SPARC64_COMPAT_H */ -- 2.9.0

[PATCH 4.4 11/97] time: Change posix clocks ops interfaces to use timespec64

by Greg Kroah-Hartman

4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Deepa Dinamani <deepa.kernel(a)gmail.com> [ Upstream commit d340266e19ddb70dbd608f9deedcfb35fdb9d419 ] struct timespec is not y2038 safe on 32 bit machines. The posix clocks apis use struct timespec directly and through struct itimerspec. Replace the posix clock interfaces to use struct timespec64 and struct itimerspec64 instead. Also fix up their implementations accordingly. Note that the clock_getres() interface has also been changed to use timespec64 even though this particular interface is not affected by the y2038 problem. This helps verification for internal kernel code for y2038 readiness by getting rid of time_t/ timeval/ timespec.

[PATCH 4.9 015/177] time: Change posix clocks ops interfaces to use timespec64

by Greg Kroah-Hartman

4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Deepa Dinamani <deepa.kernel(a)gmail.com> [ Upstream commit d340266e19ddb70dbd608f9deedcfb35fdb9d419 ] struct timespec is not y2038 safe on 32 bit machines. The posix clocks apis use struct timespec directly and through struct itimerspec. Replace the posix clock interfaces to use struct timespec64 and struct itimerspec64 instead. Also fix up their implementations accordingly. Note that the clock_getres() interface has also been changed to use timespec64 even though this particular interface is not affected by the y2038 problem. This helps verification for internal kernel code for y2038 readiness by getting rid of time_t/ timeval/ timespec.

[PATCH v4 00/10] posix_clocks: Prepare syscalls for 64 bit time_t conversion

by Deepa Dinamani

The series is a preparation series for individual architectures to use 64 bit time_t syscalls in compat and 32 bit emulation modes. This is a follow up to the series Arnd Bergmann posted: https://sourceware.org/ml/libc-alpha/2015-05/msg00070.html [1] Thomas, Arnd, this seems ready to be merged now. Can you help get this merged? Big picture is as per the lwn article: https://lwn.net/Articles/643234/ [2] The series is directed at converting posix clock syscalls: clock_gettime, clock_settime, clock_getres and clock_nanosleep to use a new data structure __kernel_timespec at syscall boundaries. __kernel_timespec maintains 64 bit time_t across all execution modes. vdso will be handled as part of each architecture when they enable support for 64 bit time_t. The compat syscalls are repurposed to provide backward compatibility by using them as native syscalls as well for 32 bit architectures. They will continue to use timespec at syscall boundaries. CONFIG_64_BIT_TIME controls whether the syscalls use __kernel_timespec or timespec at syscall boundaries. The series does the following: 1. Enable compat syscalls on 32 bit architectures. 2. Add a new __kernel_timespec type to be used as the data structure for all the new syscalls. 3. Add new config CONFIG_64BIT_TIME(intead of the CONFIG_COMPAT_TIME in [1] and [2] to switch to new definition of __kernel_timespec. It is the same as struct timespec otherwise. 4. Add new CONFIG_32BIT_TIME to conditionally compile compat syscalls. * Changes since v3: * Updated include file ordering * Changes since v2: * Dropped the ARCH_HAS_64BIT_TIME config. * Fixed zeroing out of higher order bits of tv_nsec for real. * Addressed minor review comments from v1. * Changes since v1: * Introduce CONFIG_32BIT_TIME * Fixed zeroing out of higher order bits of tv_nsec * Included Arnd's changes to fix up use of compat headers I decided against using LEGACY_TIME_SYSCALLS to conditionally compile legacy time syscalls such as sys_nanosleep because this will need to enclose compat_sys_nanosleep as well. So, defining it as config LEGACY_TIME_SYSCALLS def_bool 64BIT || !64BIT_TIME will not include compat_sys_nanosleep. We will instead need a new config to exclusively mark legacy syscalls.

This is a follow up to the series Arnd Bergmann posted: https://sourceware.org/ml/libc-alpha/2015-05/msg00070.html [1] Big picture is as per the lwn article: https://lwn.net/Articles/643234/ [2] The series is directed at converting posix clock syscalls: clock_gettime, clock_settime, clock_getres and clock_nanosleep to use a new data structure __kernel_timespec at syscall boundaries. __kernel_timespec maintains 64 bit time_t across all execution modes. vdso will be handled as part of each architecture when they enable support for 64 bit time_t. The compat syscalls are repurposed to provide backward compatibility by using them as native syscalls as well for 32 bit architectures. They will continue to use timespec at syscall boundaries. CONFIG_64_BIT_TIME controls whether the syscalls use __kernel_timespec or timespec at syscall boundaries. The series does the following: 1. Enable compat syscalls on 32 bit architectures. 2. Add a new __kernel_timespec type to be used as the data structure for all the new syscalls. 3. Add new config CONFIG_64BIT_TIME(intead of the CONFIG_COMPAT_TIME in [1] and [2] to switch to new definition of __kernel_timespec. It is the same as struct timespec otherwise. 4. Add new CONFIG_32BIT_TIME to conditionally compile compat syscalls. * Changes since v2: * Dropped the ARCH_HAS_64BIT_TIME config. * Fixed zeroing out of higher order bits of tv_nsec for real. * Addressed minor review comments from v1. * Changes since v1: * Introduce CONFIG_32BIT_TIME * Fixed zeroing out of higher order bits of tv_nsec * Included Arnd's changes to fix up use of compat headers I decided against using LEGACY_TIME_SYSCALLS to conditionally compile legacy time syscalls such as sys_nanosleep because this will need to enclose compat_sys_nanosleep as well. So, defining it as config LEGACY_TIME_SYSCALLS def_bool 64BIT || !64BIT_TIME will not include compat_sys_nanosleep. We will instead need a new config to exclusively mark legacy syscalls.

[PATCH AUTOSEL for 4.4 016/101] time: Change posix clocks ops interfaces to use timespec64

by Sasha Levin

From: Deepa Dinamani <deepa.kernel(a)gmail.com> [ Upstream commit d340266e19ddb70dbd608f9deedcfb35fdb9d419 ] struct timespec is not y2038 safe on 32 bit machines. The posix clocks apis use struct timespec directly and through struct itimerspec. Replace the posix clock interfaces to use struct timespec64 and struct itimerspec64 instead. Also fix up their implementations accordingly. Note that the clock_getres() interface has also been changed to use timespec64 even though this particular interface is not affected by the y2038 problem. This helps verification for internal kernel code for y2038 readiness by getting rid of time_t/ timeval/ timespec.

[PATCH v6 0/4]

by Deepa Dinamani

The series is aimed at adding support to maintain individual timestamp ranges for filesystems. This helps futimens, utimensat and utimes syscalls to conform to POSIX defined behavior when the time being set is outside of the corresponding filesystem's supported limits. The series was developed with discussions and guidance from Arnd Bergmann. The original thread is at https://lkml.org/lkml/2016/11/2/294 I will be submitting follow up kernel patches to update all filesystems. Currently ext4 is the only filesystem that reflects correct limits. The branch is available at https://github.com/deepa-hub/vfs.git refs/heads/range Changes since v5: * Dropped y2038-specific changes Changes since v4: * Added documentation for boot param Changes since v3: * Remove redundant initializations in libfs.c * Change early_param to __setup similar to other root mount options. * Fix documentation warning Changes since v2: * Introduce early boot param override for checks. * Drop afs patch for timestamp limits. Changes since v1: * return EROFS on mount errors * fix mtime copy/paste error in utimes Deepa Dinamani (4): vfs: Add file timestamp range support ext4: Initialize timestamps limits vfs: Add timestamp_truncate() api utimes: Clamp the timestamps before update fs/ext4/ext4.h | 4 ++++ fs/ext4/super.c | 7 ++++++- fs/inode.c | 32 +++++++++++++++++++++++++++++++- fs/super.c | 2 ++ fs/utimes.c | 17 +++++++++++++---- include/linux/fs.h | 3 +++ include/linux/time64.h | 2 ++ 7 files changed, 61 insertions(+), 6 deletions(-) -- 2.14.1 Cc: "Theodore Ts'o" <tytso(a)mit.edu> Cc: Andreas Dilger <adilger.kernel(a)dilger.ca> Cc: linux-ext4(a)vger.kernel.org

[PATCH] scsi: arcmsr: avoid do_gettimeofday

by Arnd Bergmann

The arcmsr uses its own implementation of time_to_tm(), along with do_gettimeofday() to read the current time. While the algoritm used here is fine in principle, it suffers from two problems: - it assigns the seconds portion of the timeval to a 32-bit unsigned integer that overflows in 2106 even on 64-bit architectures. - do_gettimeofday() returns a time_t that overflows in 2038 on all 32-bit systems. This changes the time retrieval function to ktime_get_real_seconds(), which returns a proper 64-bit value, and replaces the open-coded time_to_tm() algorithm with a call to the safe time64_to_tm(). I checked way all numbers are indexed and found that months are given in range 0..11 while the days are in range 1..31, same as 'struct tm', but the year value that the firmware expects starts in 2000 while 'struct tm' is based on year 1900, so it needs a small adjustment.

[PATCH] nilfs2: use time64_t internally

by Arnd Bergmann

The superblock and segment timestamps are used only internally in nilfs2 and can be read out using sysfs. Since we are using the old 'get_seconds()' interface and store the data as timestamps, the behavior differs slightly between 64-bit and 32-bit kernels, the latter will show incorrect timestamps after 2038 in sysfs, and presumably fail completely in 2106 as comparisons go wrong. This changes nilfs2 to use time64_t with ktime_get_real_seconds() to handle timestamps, making the behavior consistent and correct on both 32-bit and 64-bit machines. The on-disk format already uses 64-bit timestamps, so nothing changes there.

[PATCH] [RESEND] vmwgfx: use monotonic event timestamps

by Arnd Bergmann

DRM_VMW_EVENT_FENCE_SIGNALED (struct drm_vmw_event_fence) and DRM_EVENT_VBLANK (struct drm_event_vblank) pass timestamps in 32-bit seconds/microseconds format. As of commit c61eef726a78 ("drm: add support for monotonic vblank timestamps"), other DRM drivers use monotonic times for drm_event_vblank, but vmwgfx still uses CLOCK_REALTIME for both events, which suffers from the y2038/y2106 overflow as well as time jumps. For consistency, this changes vmwgfx to use ktime_get_ts64 as well, which solves those problems and avoids the deprecated do_gettimeofday() function. This should be transparent to to user space, as long as it doesn't compare the time against the result of gettimeofday().

[PATCH] pps: parport: use timespec64 instead of timespec

by Arnd Bergmann

getnstimeofday() is deprecated, so I'm converting this to use ktime_get_real_ts64() as a safe replacement. I considered using ktime_get_real() instead, but since the algorithm here depends on the exact timing, I decided to introduce fewer changes and leave the code that determines the nanoseconds since the last seconds wrap untouched. It's not entirely clear to me whether we should also change the time base to CLOCK_BOOTTIME or CLOCK_TAI. With boottime, we would be independent of changes due to settimeofday() and only see the speed adjustment from the upstream clock source, with the downside of having the signal be at an arbirary offset from the start of the UTC second signal. With CLOCK_TAI, we would use the same offset from the UTC second as before and still suffer from settimeofday() adjustments, but would be less confused during leap seconds. Both boottime and tai only offer usable (i.e. avoiding ktime_t to timespec64 conversion) interfaces for ktime_t though, so either way, changing it wouldn't take significantly more work. CLOCK_MONOTONIC could be used with ktime_get_ts64(), but would lose synchronization across a suspend/resume cycle, which seems worse.

[PATCH 1/8] [media] uvc_video: use ktime_t for stats

Would it be better to start this interface out by defining it using a 64-bit timeout structure? The downside would be that the user space syscall wrappers have to start out with a conversion, if we don't do it, then the opposite conversion would have to get added later. Arnd

[PATCH v6 0/1] Make input drivers y2038 safe

The series is aimed at making input events y2038 safe. It extends the lifetime of the realtime timestamps in the events to year 2106. The series is also a necessary update as glibc is set to provide 64 bit time_t support for 32 bit binaries. glibc plan is detailed at https://sourceware.org/glibc/wiki/Y2038ProofnessDesign . The series is a result of discussions with Arnd Bergmann and Dmitry Torokhov at last Plumbers. The plan is to deprecate realtime timestamps anyway as they are not appropriate for these timestamps as noted in the patch a80b83b7b8 by John Stultz. The design also updates the format of the input events read/ written to the device nodes. This breaks 32 bit interface to the input events at compile time as preferred by the maintainer. The userspace library changes to libevdev, libuinput and mtdev will be posted to the respective mailing groups for review.

[PATCH v2 00/10] posix_clocks: Prepare syscalls for 64 bit time_t conversion

by Deepa Dinamani

The series is a preparation series for individual architectures to use 64 bit time_t syscalls in compat and 32 bit emulation modes. This is a follow up to the series Arnd Bergmann posted: https://sourceware.org/ml/libc-alpha/2015-05/msg00070.html [1] Big picture is as per the lwn article: https://lwn.net/Articles/643234/ [2] The series is directed at converting posix clock syscalls: clock_gettime, clock_settime, clock_getres and clock_nanosleep to use a new data structure __kernel_timespec at syscall boundaries. __kernel_timespec maintains 64 bit time_t across all execution modes. vdso will be handled as part of each architecture when they enable support for 64 bit time_t. The compat syscalls are repurposed to provide backward compatibility by using them as native syscalls as well for 32 bit architectures. They will continue to use timespec at syscall boundaries. CONFIG_64_BIT_TIME controls whether the syscalls use __kernel_timespec or timespec at syscall boundaries. The series does the following: 1. Enable compat syscalls on 32 bit architectures. 2. Add a new __kernel_timespec type to be used as the data structure for all the new syscalls. 3. Add new config CONFIG_64BIT_TIME(intead of the CONFIG_COMPAT_TIME in [1] and [2] to switch to new definition of __kernel_timespec. It is the same as struct timespec otherwise. 4. Add new CONFIG_32BIT_TIME to conditionally compile compat syscalls. * Changes since v1: * Introduce CONFIG_32BIT_TIME * Fixed zeroing out of higher order bits of tv_nsec * Included Arnd's changes to fix up use of compat headers I decided against using LEGACY_TIME_SYSCALLS to conditionally compile legacy time syscalls such as sys_nanosleep because this will need to enclose compat_sys_nanosleep as well. So, defining it as config LEGACY_TIME_SYSCALLS def_bool 64BIT || !64BIT_TIME will not include compat_sys_nanosleep. We will instead need a new config to exclusively mark legacy syscalls.

[PATCH 1/2] i40iw: remove unused 'timeval' struct member

by Arnd Bergmann

There is a stale entry in i40iw_cm_tcp_context that apparently was copied from the 'nes' driver but never used in i40iw. I'm trying to kill off all users of timeval as part of the y2038-safety work, so let's just remove this one.

[PATCH] iio: common: ssp_sensors: use ktime_get_real_ns() timestamps

by Arnd Bergmann

getnstimeofday() suffers from the overflow in y2038 on 32-bit architectures and requires a conversion into the nanosecond format that we want here. This changes ssp_parse_dataframe() to use ktime_get_real_ns() directly, which does not have that problem. An open question is what time base should be used here. Normally timestamps should use ktime_get_ns() or ktime_get_boot_ns() to read monotonic time instead of "real" time, which suffers from time jumps due to settimeofday() calls or leap seconds.

[PATCH 0/9] posix_clocks: Prepare syscalls for 64 bit time_t conversion

by Deepa Dinamani

The series is a preparation series for individual architectures to use 64 bit time_t syscalls in compat and 32 bit emulation modes. This is a follow up to the series Arnd Bergmann posted: https://sourceware.org/ml/libc-alpha/2015-05/msg00070.html Big picture is as per the lwn article: https://lwn.net/Articles/643234/ The series is directed at converting posix clock syscalls: clock_gettime, clock_settime, clock_getres and clock_nanosleep to use a new data structure __kernel_timespec at syscall boundaries. __kernel_timespec maintains 64 bit time_t across all execution modes. vdso will be handled as part of each architecture when they enable support for 64 bit time_t. The compat syscalls are repurposed to provide backward compatibility by using them as native syscalls as well for 32 bit architectures. They will continue to use timespec at syscall boundaries. CONFIG_64_BIT_TIME controls whether the syscalls use __kernel_timespec or timespec at syscall boundaries. The series does the following: 1. Enable compat syscalls unconditionally. 2. Add a new __kernel_timespec type to be used as the data structure for all the new syscalls. 3. Add new config CONFIG_64BIT_TIME(intead of the CONFIG_COMPAT_TIME in [1] and [2] to switch to new definition of __kernel_timespec. It is the same as struct timespec otherwise. Arnd Bergmann (1): y2038: introduce CONFIG_64BIT_TIME Deepa Dinamani (8): include: Move compat_timespec/ timeval to compat_time.h compat: Make compat helpers independent of CONFIG_COMPAT compat: enable compat_get/put_timespec64 always posix-clocks: Enable compat syscalls always include: Add new y2038 safe __kernel_timespec fix get_timespec64() for y2038 safe compat interfaces change time types to new y2038 safe __kernel_* types nanosleep: change time types to safe __kernel_* types arch/Kconfig | 11 ++++ arch/arm64/include/asm/compat.h | 11 ---- arch/arm64/include/asm/stat.h | 1 + arch/arm64/kernel/hw_breakpoint.c | 1 - arch/arm64/kernel/perf_regs.c | 2 +- arch/arm64/kernel/process.c | 1 - arch/mips/include/asm/compat.h | 11 ---- arch/mips/kernel/signal32.c | 2 +- arch/parisc/include/asm/compat.h | 11 ---- arch/powerpc/include/asm/compat.h | 11 ---- arch/powerpc/kernel/asm-offsets.c | 2 +- arch/powerpc/oprofile/backtrace.c | 2 +- arch/s390/hypfs/hypfs_sprp.c | 1 - arch/s390/include/asm/compat.h | 11 ---- arch/s390/include/asm/elf.h | 3 +- arch/s390/kvm/priv.c | 1 - arch/s390/pci/pci_clp.c | 1 - arch/sparc/include/asm/compat.h | 11 ---- arch/tile/include/asm/compat.h | 11 ---- arch/x86/events/core.c | 2 +- arch/x86/include/asm/compat.h | 11 ---- arch/x86/include/asm/ftrace.h | 2 +- arch/x86/include/asm/sys_ia32.h | 2 +- arch/x86/kernel/sys_x86_64.c | 2 +- drivers/s390/block/dasd_ioctl.c | 1 - drivers/s390/char/fs3270.c | 1 - drivers/s390/char/sclp_ctl.c | 1 - drivers/s390/char/vmcp.c | 1 - drivers/s390/cio/chsc_sch.c | 1 - drivers/s390/net/qeth_core_main.c | 2 +- drivers/staging/pi433/pi433_if.c | 2 +- include/linux/compat.h | 7 ++- include/linux/compat_time.h | 23 +++++++++ include/linux/restart_block.h | 7 +-- include/linux/syscalls.h | 12 ++--- include/linux/time.h | 4 +- include/linux/time64.h | 10 +++- include/uapi/asm-generic/posix_types.h | 1 + include/uapi/linux/time.h | 7 +++ kernel/Makefile | 2 +- kernel/compat.c | 92 ++++++++++++++++++---------------- kernel/time/hrtimer.c | 7 +-- kernel/time/posix-stubs.c | 12 ++--- kernel/time/posix-timers.c | 20 ++++---- kernel/time/time.c | 10 +++- 45 files changed, 152 insertions(+), 195 deletions(-) create mode 100644 include/linux/compat_time.h base-commit: d9e0e63d9a6f88440eb201e1491fcf730272c706 -- 2.11.0 Cc: acme(a)kernel.org Cc: benh(a)kernel.crashing.org Cc: borntraeger(a)de.ibm.com Cc: catalin.marinas(a)arm.com Cc: cmetcalf(a)mellanox.com Cc: cohuck(a)redhat.com Cc: davem(a)davemloft.net Cc: deller(a)gmx.de Cc: devel(a)driverdev.osuosl.org Cc: gerald.schaefer(a)de.ibm.com Cc: gregkh(a)linuxfoundation.org Cc: heiko.carstens(a)de.ibm.com Cc: hoeppner(a)linux.vnet.ibm.com Cc: hpa(a)zytor.com Cc: jejb(a)parisc-linux.org Cc: jwi(a)linux.vnet.ibm.com Cc: linux-api(a)vger.kernel.org Cc: linux-arch(a)vger.kernel.org Cc: linux-kernel(a)vger.kernel.org Cc: linux-mips(a)linux-mips.org Cc: linux-parisc(a)vger.kernel.org Cc: linuxppc-dev(a)lists.ozlabs.org Cc: linux-s390(a)vger.kernel.org Cc: mark.rutland(a)arm.com Cc: mingo(a)redhat.com Cc: mpe(a)ellerman.id.au Cc: oberpar(a)linux.vnet.ibm.com Cc: oprofile-list(a)lists.sf.net Cc: paulus(a)samba.org Cc: peterz(a)infradead.org Cc: ralf(a)linux-mips.org Cc: rostedt(a)goodmis.org Cc: rric(a)kernel.org Cc: schwidefsky(a)de.ibm.com Cc: sebott(a)linux.vnet.ibm.com Cc: sparclinux(a)vger.kernel.org Cc: sth(a)linux.vnet.ibm.com Cc: ubraun(a)linux.vnet.ibm.com Cc: will.deacon(a)arm.com Cc: x86(a)kernel.org

[PATCH] ath10k: use 64-bit crash dump timestamps

by Arnd Bergmann

The dump format uses 64-bit timestamps already, but calling getnstimeofday() only returns a 32-bit number on 32-bit architectures, so that will overflow in y2038. This changes it to use ktime_get_real_ts64() instead.
