----------------------------------------------------------------
y2038: core, driver and file system changes
These are updates to device drivers and file systems that for some reason
or another were not included in the kernel in the previous y2038 series.
I've gone through all users of time_t again to make sure the kernel is
in a long-term maintainable state, replacing all remaining references
to time_t with safe alternatives.
Some related parts of the series were picked up into the nfsd, xfs,
alsa and v4l2 trees. A final set of patches in linux-mm removes the now
unused time_t/timeval/timespec types and helper functions after all five
branches are merged for linux-5.6, ensuring that no new users get merged.
As a result, linux-5.6, or my backport of the patches to 5.4 [1], should
be the first release that can serve as a base for a 32-bit system designed
to run beyond year 2038, with a few remaining caveats:
- All user space must be compiled with a 64-bit time_t, which will be
supported in the coming musl-1.2 and glibc-2.32 releases, along with
installed kernel headers from linux-5.6 or higher.
- Applications that use the system call interfaces directly need to be
ported to use the time64 syscalls added in linux-5.1 in place of the
existing system calls. This impacts most users of futex() and seccomp()
as well as programming languages that have their own runtime environment
not based on libc.
- Applications that use a private copy of kernel uapi header files or
their contents may need to update to the linux-5.6 version, in
particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h,
linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h.
- A few remaining interfaces cannot be changed to pass a 64-bit time_t
in a compatible way, so they must be configured to use CLOCK_MONOTONIC
times or (with a y2106 problem) unsigned 32-bit timestamps. Most
importantly this impacts all users of 'struct input_event'.
- All y2038 problems that are present on 64-bit machines also apply to
32-bit machines. In particular this affects file systems with on-disk
timestamps using signed 32-bit seconds: ext4 with ext3-style small
inodes, ext2, xfs (to be fixed soon) and ufs.
Changes since v1 [2]:
- Add Acks I received
- Rebase to v5.5-rc1, dropping patches that got merged already
- Add NFS, XFS and the final three patches from another series
- Rewrite etnaviv patches
- Add one late revert to avoid an etnaviv regression

musl is moving to a default of 64-bit time_t on all architectures,
glibc will follow later. This breaks reading timestamps through cmsg
data with the HCI_TIME_STAMP socket option.
Change both copies of hcidump to work on all architectures. This also
fixes x32, which has never worked, and carefully avoids breaking sparc64,
which is another special case.
I have only compiled this on one architecture, please at least test
it to ensure there are no regressions. The toolchain binaries from
http://musl.cc/ should allow testing with a 64-bit time_t, but it may
be hard to build all the dependencies first.
libpcap has the same bug and needs a similar fix to work on future
32-bit Linux systems. Everything else apparently uses the generic
SO_TIMESTAMP timestamps, which work correctly when using new enough
kernels with a time64 libc.

2.20.0
I noticed earlier this week that the HCI_CMSG_TSTAMP/HCI_TIME_STAMP
interface has no time64 equivalent, as we apparently missed that when
converting the normal socket timestamps to support both time32 and time64
variants of the sockopt and cmsg data.
The interface was originally added back in 2002 by Maksim Krasnyanskiy
when bluetooth support first became non-experimental.
When using HCI_TIME_STAMP on a 32-bit system with a time64
libc, users will interpret the { s32 tv_sec; s32 tv_usec } layout of
the kernel as { s64 tv_sec; ... }, which puts complete garbage
into the timestamp regardless of whether this code runs before or
after y2038. From looking at codesearch.debian.org, I found two
users of this: libpcap and hcidump. There are probably others that
are not part of Debian.
Fixing this the same was as normal socket timestamps is not possible
because include/net/bluetooth/hci.h is not an exported UAPI header.
This means any changes to it for defining HCI_TIME_STAMP conditionally
would be ignored by applications that use a different copy of the
header.
I can see three possible ways forward:
1. move include/net/bluetooth/hci.h to include/uapi/, add a conditional
definition of HCI_TIME_STAMP and make the kernel code support
both formats. Then change applications to rely on that version of
header file to get the correct definition but not change application code.
2. Leave the kernel completely unchanged and modify only the users
to not expect the output to be a 'struct timeval' but interpret as
as { uint32_t tv_sec; int32_t tv_usec; } structure on 32-bit architectures,
which will work until the unsigned time overflows 86 years from now
in 2106 (same as the libpcap on-disk format).
3. Add support for the normal SO_TIMESTAMPNS_NEW sockopt in
HCI, providing timestamps in the unambiguous { long long tv_sec;
long long tv_nsec; } format to user space, and change applications
to use that if supported by the kernel.

Hi Andrew,
Can you add these to your patches for linux-5.6?
I have y2038 cleanups for sound, v4l, nfsd, scsi and xfs that are
merged in the respective subsystem trees, as well as another
series of individual patches queued up in my own y2038 tree.
With all that work merged, most of include/linux/time32.h
and some other related code can be removed from the kernel,
so it would be good to send these at the end of the coming
merge window, and to give them some more testing in linux-next
to make sure we don't gain any new users.

The compat_time_t type has been removed everywhere else,
as most users rely on old_time32_t for both native and
compat mode handling of 32-bit time_t.
Remove the last one in xfs.

As explained in https://www.spinics.net/lists/linux-xfs/msg35524.html
I've dropped the patch "xfs: disallow broken ioctls without
compat-32-bit-time" for this submission but will get to that later
when doing that as a treewide change.
Please apply these two for v5.6 in the meantime so we can kill off
compat_time_t, time_t and get_seconds() for good.

----------------------------------------------------------------
block, scsi: final compat_ioctl cleanup
This series concludes the work I did for linux-5.5 on the compat_ioctl()
cleanup, killing off fs/compat_ioctl.c and block/compat_ioctl.c by moving
everything into drivers.
Overall this would be a reduction both in complexity and line count, but
as I'm also adding documentation the overall number of lines increases
in the end.
My plan was originally to keep the SCSI and block parts separate.
This did not work easily because of interdependencies: I cannot
do the final SCSI cleanup in a good way without first addressing the
CDROM ioctls, so this is one series that I hope could be merged through
either the block or the scsi git trees, or possibly both if you can
pull in the same branch.
The series comes in these steps:
1. clean up the sg v3 interface as suggested by Linus. I have
talked about this with Doug Gilbert as well, and he would
rebase his sg v4 patches on top of "compat: scsi: sg: fix v3
compat read/write interface"
2. Actually moving handlers out of block/compat_ioctl.c and
block/scsi_ioctl.c into drivers, mixed in with cleanup
patches
3. Document how to do this right. I keep getting asked about this,
and it helps to point to some documentation file.
The branch is based on another one that fixes a couple of bugs found
during the creation of this series.
Changes since v2:
- Rebase to v5.5-rc4, which contains the earlier bugfixes
- Fix sr_block_compat_ioctl() error handling bug found by
Ben Hutchings
- Fix idecd_locked_compat_ioctl() compat_ptr() bug
- Don't try to handle HDIO_DRIVE_TASKFILE in drivers/ide
- More documentation improvements
Changes since v1:
- move out the bugfixes into a branch for itself
- clean up scsi sg driver further as suggested by Christoph Hellwig
- avoid some ifdefs by moving compat_ptr() out of asm/compat.h
- split out the blkdev_compat_ptr_ioctl function; bug spotted by
Ben Hutchings
- Improve formatting of documentation

Hi Bruce, Chuck,
NFSd is one of the last areas of the kernel that is not y2038 safe
yet, this series addresses the remaining issues here.
I did not get any comments for the first version I posted [1], and
I hope this just means that everything was fine and you plan to
merge this soon ;-)
I uploaded a git branch to [2] for testing.
Please review and merge for linux-5.6 so we can remove the 32-bit
time handling from that release.
Arnd
Changes from v1:
- separate nfs and nfsd, as most of the nfs changes are merged now
- rebase to v5.5
