[PATCH v6 00/43] compat_ioctl: remove most of fs/compat_ioctl.c

by Arnd Bergmann

As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers. I have patches for those as well, but they need more testing or possibly a rewrite. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- Everything in here was posted one or more times already, sending the whole series again for review, I hope to get some input on those patches that have not already been reviewed.

[PATCH] io_uring: use __kernel_timespec in timeout ABI

by Arnd Bergmann

All system calls use struct __kernel_timespec instead of the old struct timespec, but this one was just added with the old-style ABI. Change it now to enforce the use of __kernel_timespec, avoiding ABI confusion and the need for compat handlers on 32-bit architectures. Any user space caller will have to use __kernel_timespec now, but this is unambiguous and works for any C library regardless of the time_t definition. A nicer way to specify the timeout would have been a less ambiguous 64-bit nanosecond value, but I suppose it's too late now to change that as this would impact both 32-bit and 64-bit users.

At mount time, a warning is now printed for any file system that can represent current timestamps but not future timestamps more than 30 years into the future, similar to the arbitrary 30 year limit that was added to settimeofday(). This was picked as a compromise to warn users to migrate to other file systems (e.g. ext4 instead of ext3) when they need the file system to survive beyond 2038 (or similar limits in other file systems), but not get in the way of normal usage.

[PATCH 1/2] ipc: fix semtimedop for generic 32-bit architectures

by Arnd Bergmann

As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1 broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on 32-bit") changed all system calls on all architectures that take a 32-bit time_t to point to the _time32 implementation, but left out semtimedop in the asm-generic header. This affects all 32-bit architectures using asm-generic/unistd.h: h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky. The notable exception is riscv32, which has dropped support for the time32 system calls entirely.

[PATCH] adfs: Fill in max and min timestamps in sb

by Deepa Dinamani

Fill in the appropriate limits to avoid inconsistencies in the vfs cached inode times when timestamps are outside the permitted range. Note that the min timestamp is assumed to be 01 Jan 1970 00:00:00 (Unix epoch). This is consistent with the way we convert timestamps in adfs_adfs2unix_time().

[PATCH v8 00/20] vfs: Add support for timestamp limits

by Deepa Dinamani

The series is an update and a more complete version of the previously posted series at https://lore.kernel.org/linux-fsdevel/20180122020426.2988-1-deepa.kernel@gm… Thanks to Arnd Bergmann for doing a few preliminary reviews. They helped me fix a few issues I had overlooked. The limits (sometimes granularity also) for the filesystems updated here are according to the following table: File system Time type Start year Expiration year Granularity cramfs fixed 0 0 romfs fixed 0 0 pstore ascii seconds (27 digit ascii) S64_MIN S64_MAX 1 coda INT64 S64_MIN S64_MAX 1 omfs 64-bit milliseconds 0 U64_MAX/ 1000 NSEC_PER_MSEC befs unsigned 48-bit seconds 0 0xffffffffffff alloc_super bfs unsigned 32-bit seconds 0 U32_MAX alloc_super efs unsigned 32-bit seconds 0 U32_MAX alloc_super ext2 signed 32-bit seconds S32_MIN S32_MAX alloc_super ext3 signed 32-bit seconds S32_MIN S32_MAX alloc_super ext4 (old) signed 32-bit seconds S32_MIN S32_MAX alloc_super ext4 (extra) 34-bit seconds, 30-bit ns S32_MIN 0x37fffffff 1 freevxfs u32 secs/usecs 0 U32_MAX alloc_super jffs2 unsigned 32-bit seconds 0 U32_MAX alloc_super jfs unsigned 32-bit seconds/ns 0 U32_MAX 1 minix unsigned 32-bit seconds 0 U32_MAX alloc_super orangefs u64 seconds 0 U64_MAX alloc_super qnx4 unsigned 32-bit seconds 0 U32_MAX alloc_super qnx6 unsigned 32-bit seconds 0 U32_MAX alloc_super reiserfs unsigned 32-bit seconds 0 U32_MAX alloc_super squashfs unsigned 32-bit seconds 0 U32_MAX alloc_super ufs1 signed 32-bit seconds S32_MIN S32_MAX NSEC_PER_SEC ufs2 signed 64-bit seconds/u32 ns S64_MIN S64_MAX 1 xfs signed 32-bit seconds/ns S32_MIN S32_MAX 1 ceph unsigned 32-bit second/ns 0 U32_MAX 1000 sysv unsigned 32-bit seconds 0 U32_MAX alloc_super affs u32 day, min, ticks 1978 u32_max days NSEC_PER_SEC nfsv2 unsigned 32-bit seconds/ns 0 U32_MAX 1 nfsv3 unsigned 32-bit seconds/ns 0 U32_MAX 1000 nfsv4 u64 seconds/u32 ns S64_MIN S64_MAX 1000 isofs u8 year since 1900 (fixable) 1900 2155 alloc_super hpfs unsigned 32-bit seconds 1970 2106 alloc_super fat 7-bit years, 2s resolution 1980 2107 cifs (smb) 7-bit years 1980 2107 cifs (modern) 64-bit 100ns since 1601 1601 30828 adfs 40-bit cs since 1900 1900 2248 9p (9P2000) unsigned 32-bit seconds 1970 2106 9p (9P2000.L) signed 64-bit seconds, ns 1970 S64_MAX Granularity column filled in by the alloc_super() in the above table indicates that the granularity is NSEC_PER_SEC. Note that anything not mentioned above still has the default limits S64_MIN..S64_MAX. The patches in the series are as structured below: 1. Add vfs support to maintain the limits per filesystem. 2. Add a new timestamp_truncate() api for clamping timestamps according to the filesystem limits. 3. Add a warning for mount syscall to indicate the impending expiry of timestamps. 4. Modify utimes to clamp the timestamps. 5. Fill in limits for filesystems. A test for checking file system timestamp limits has been posted at https://www.spinics.net/lists/fstests/msg12262.html Changes since v7: * Dropped fat modifications from timespec_truncate patch * Leverage timestamp_truncate function in utimes * Added a fix for pstore ramoops timestamps * Added ext4 warning for inodes without room for extended timestamps. * Made mount warning more human readable Changes since v6: * No change in mount behavior because of expiry of timestamps. * Included limits for more filesystems. 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 (20): vfs: Add file timestamp range support vfs: Add timestamp_truncate() api timestamp_truncate: Replace users of timespec64_trunc mount: Add mount warning for impending timestamp expiry utimes: Clamp the timestamps before update fs: Fill in max and min timestamps in superblock 9p: Fill min and max timestamps in sb adfs: Fill in max and min timestamps in sb ext4: Initialize timestamps limits fs: nfs: Initialize filesystem timestamp ranges fs: cifs: Initialize filesystem timestamp ranges fs: fat: Initialize filesystem timestamp ranges fs: affs: Initialize filesystem timestamp ranges fs: sysv: Initialize filesystem timestamp ranges fs: ceph: Initialize filesystem timestamp ranges fs: orangefs: Initialize filesystem timestamp ranges fs: hpfs: Initialize filesystem timestamp ranges fs: omfs: Initialize filesystem timestamp ranges pstore: fs superblock limits isofs: Initialize filesystem timestamp ranges fs/9p/vfs_super.c | 6 +++++- fs/adfs/adfs.h | 13 +++++++++++++ fs/adfs/inode.c | 8 ++------ fs/adfs/super.c | 2 ++ fs/affs/amigaffs.c | 2 +- fs/affs/amigaffs.h | 3 +++ fs/affs/inode.c | 4 ++-- fs/affs/super.c | 4 ++++ fs/attr.c | 21 ++++++++++++--------- fs/befs/linuxvfs.c | 2 ++ fs/bfs/inode.c | 2 ++ fs/ceph/super.c | 2 ++ fs/cifs/cifsfs.c | 22 ++++++++++++++++++++++ fs/cifs/netmisc.c | 14 +++++++------- fs/coda/inode.c | 3 +++ fs/configfs/inode.c | 12 ++++++------ fs/cramfs/inode.c | 2 ++ fs/efs/super.c | 2 ++ fs/ext2/super.c | 2 ++ fs/ext4/ext4.h | 10 +++++++++- fs/ext4/super.c | 17 +++++++++++++++-- fs/f2fs/file.c | 21 ++++++++++++--------- fs/fat/inode.c | 12 ++++++++++++ fs/freevxfs/vxfs_super.c | 2 ++ fs/hpfs/hpfs_fn.h | 6 ++---- fs/hpfs/super.c | 2 ++ fs/inode.c | 33 ++++++++++++++++++++++++++++++++- fs/isofs/inode.c | 7 +++++++ fs/jffs2/fs.c | 3 +++ fs/jfs/super.c | 2 ++ fs/kernfs/inode.c | 7 +++---- fs/minix/inode.c | 2 ++ fs/namespace.c | 33 ++++++++++++++++++++++++++++++++- fs/nfs/super.c | 20 +++++++++++++++++++- fs/ntfs/inode.c | 21 ++++++++++++--------- fs/omfs/inode.c | 4 ++++ fs/orangefs/super.c | 2 ++ fs/pstore/ram.c | 2 ++ fs/qnx4/inode.c | 2 ++ fs/qnx6/inode.c | 2 ++ fs/reiserfs/super.c | 3 +++ fs/romfs/super.c | 2 ++ fs/squashfs/super.c | 2 ++ fs/super.c | 2 ++ fs/sysv/super.c | 5 ++++- fs/ubifs/file.c | 21 ++++++++++++--------- fs/ufs/super.c | 7 +++++++ fs/utimes.c | 6 ++---- fs/xfs/xfs_super.c | 2 ++ include/linux/fs.h | 5 +++++ include/linux/time64.h | 2 ++ 51 files changed, 315 insertions(+), 78 deletions(-) -- 2.17.1 Cc: adilger.kernel(a)dilger.ca Cc: adrian.hunter(a)intel.com Cc: aivazian.tigran(a)gmail.com Cc: al(a)alarsen.net Cc: anna.schumaker(a)netapp.com Cc: anton(a)enomsg.org Cc: asmadeus(a)codewreck.org Cc: ccross(a)android.com Cc: ceph-devel(a)vger.kernel.org Cc: coda(a)cs.cmu.edu Cc: codalist(a)coda.cs.cmu.edu Cc: darrick.wong(a)oracle.com Cc: dedekind1(a)gmail.com Cc: devel(a)lists.orangefs.org Cc: dsterba(a)suse.com Cc: dushistov(a)mail.ru Cc: dwmw2(a)infradead.org Cc: ericvh(a)gmail.com Cc: gregkh(a)linuxfoundation.org Cc: hch(a)infradead.org Cc: hch(a)lst.de Cc: hirofumi(a)mail.parknet.co.jp Cc: hubcap(a)omnibond.com Cc: idryomov(a)gmail.com Cc: jack(a)suse.com Cc: jaegeuk(a)kernel.org Cc: jaharkes(a)cs.cmu.edu Cc: jfs-discussion(a)lists.sourceforge.net Cc: jlbec(a)evilplan.org Cc: keescook(a)chromium.org Cc: linux-cifs(a)vger.kernel.org Cc: linux-ext4(a)vger.kernel.org Cc: linux-f2fs-devel(a)lists.sourceforge.net Cc: linux-karma-devel(a)lists.sourceforge.net Cc: linux-mtd(a)lists.infradead.org Cc: linux-nfs(a)vger.kernel.org Cc: linux-ntfs-dev(a)lists.sourceforge.net Cc: linux-xfs(a)vger.kernel.org Cc: lucho(a)ionkov.net Cc: luisbg(a)kernel.org Cc: martin(a)omnibond.com Cc: me(a)bobcopeland.com Cc: mikulas(a)artax.karlin.mff.cuni.cz Cc: nico(a)fluxnic.net Cc: phillip(a)squashfs.org.uk Cc: reiserfs-devel(a)vger.kernel.org Cc: richard(a)nod.at Cc: sage(a)redhat.com Cc: salah.triki(a)gmail.com Cc: sfrench(a)samba.org Cc: shaggy(a)kernel.org Cc: tj(a)kernel.org Cc: tony.luck(a)intel.com Cc: trond.myklebust(a)hammerspace.com Cc: tytso(a)mit.edu Cc: v9fs-developer(a)lists.sourceforge.net Cc: yuchao0(a)huawei.com Cc: zyan(a)redhat.com
