mm/filemap.c: clear page error before actual read
Mount failure issue happens under the scenario: Application forked dozens
of threads to mount the same number of cramfs images separately in docker,
but several mounts failed with high probability. Mount failed due to the
checking result of the page(read from the superblock of loop dev) is not
uptodate after wait_on_page_locked(page) returned in function cramfs_read:
wait_on_page_locked(page);
if (!PageUptodate(page)) {
...
}
The reason of the checking result of the page not uptodate: systemd-udevd
read the loopX dev before mount, because the status of loopX is Lo_unbound
at this time, so loop_make_request directly trigger the calling of io_end
handler end_buffer_async_read, which called SetPageError(page). So It
caused the page can't be set to uptodate in function
end_buffer_async_read:
if(page_uptodate && !PageError(page)) {
SetPageUptodate(page);
}
Then mount operation is performed, it used the same page which is just
accessed by systemd-udevd above, Because this page is not uptodate, it
will launch a actual read via submit_bh, then wait on this page by calling
wait_on_page_locked(page). When the I/O of the page done, io_end handler
end_buffer_async_read is called, because no one cleared the page
error(during the whole read path of mount), which is caused by
systemd-udevd reading, so this page is still in "PageError" status, which
can't be set to uptodate in function end_buffer_async_read, then caused
mount failure.
But sometimes mount succeed even through systemd-udeved read loopX dev
just before, The reason is systemd-udevd launched other loopX read just
between step 3.1 and 3.2, the steps as below:
1, loopX dev default status is Lo_unbound;
2, systemd-udved read loopX dev (page is set to PageError);
3, mount operation
1) set loopX status to Lo_bound;
==>systemd-udevd read loopX dev<==
2) read loopX dev(page has no error)
3) mount succeed
As the loopX dev status is set to Lo_bound after step 3.1, so the other
loopX dev read by systemd-udevd will go through the whole I/O stack, part
of the call trace as below:
SYS_read
vfs_read
do_sync_read
blkdev_aio_read
generic_file_aio_read
do_generic_file_read:
ClearPageError(page);
mapping->a_ops->readpage(filp, page);
here, mapping->a_ops->readpage() is blkdev_readpage. In latest kernel,
some function name changed, the call trace as below:
blkdev_read_iter
generic_file_read_iter
generic_file_buffered_read:
/*
* A previous I/O error may have been due to temporary
* failures, eg. mutipath errors.
* Pg_error will be set again if readpage fails.
*/
ClearPageError(page);
/* Start the actual read. The read will unlock the page*/
error=mapping->a_ops->readpage(flip, page);
We can see ClearPageError(page) is called before the actual read,
then the read in step 3.2 succeed.
This patch is to add the calling of ClearPageError just before the actual
read of read path of cramfs mount. Without the patch, the call trace as
below when performing cramfs mount:
do_mount
cramfs_read
cramfs_blkdev_read
read_cache_page
do_read_cache_page:
filler(data, page);
or
mapping->a_ops->readpage(data, page);
With the patch, the call trace as below when performing mount:
do_mount
cramfs_read
cramfs_blkdev_read
read_cache_page:
do_read_cache_page:
ClearPageError(page); <== new add
filler(data, page);
or
mapping->a_ops->readpage(data, page);
With the patch, mount operation trigger the calling of
ClearPageError(page) before the actual read, the page has no error if no
additional page error happen when I/O done.

mm/filemap.c: don't bother dropping mmap_sem for zero size readahead
When handling a page fault, we drop mmap_sem to start async readahead so
that we don't block on IO submission with mmap_sem held. However there's
no point to drop mmap_sem in case readahead is disabled. Handle that case
to avoid pointless dropping of mmap_sem and retrying the fault. This was
actually reported to block mlockall(MCL_CURRENT) indefinitely.

mm/Makefile: disable KCSAN for kmemleak
Kmemleak could scan task stacks while plain writes happens to those stack variables which could results in data races. For example, in sys_rt_sigaction and do_sigaction(), it could have plain writes in a 32-byte size. Since the kmemleak does not care about the actual values of a non-pointer and all do_sigaction() call sites only copy to stack variables, just disable KCSAN for kmemleak to avoid annotating anything outside Kmemleak just because Kmemleak scans everything.

mm/kmemleak.c: use address-of operator on section symbols
Clang warns:

if (__start_ro_after_init < _sdata || __end_ro_after_init > _edata)

mm/kmemleak.c:1955:60: warning: array comparison always evaluates to a constant [-Wtautological-compare]
if (__start_ro_after_init < _sdata || __end_ro_after_init > _edata)
These are not true arrays, they are linker defined symbols, which are just
addresses. Using the address of operator silences the warning and does
not change the resulting assembly with either clang/ld.lld or gcc/ld
(tested with diff + objdump -Dr).

slub: relocate freelist pointer to middle of object
In a recent discussion[1] with Vitaly Nikolenko and Silvio Cesare, it became clear that moving the freelist pointer away from the edge of allocations would likely improve the overall defensive posture of the inline freelist pointer. My benchmarks show no meaningful change to performance (they seem to show it being faster), so this looks like a reasonable change to make. Instead of having the freelist pointer at the very beginning of an allocation (offset 0) or at the very end of an allocation (effectively offset -sizeof(void *) from the next allocation), move it away from the edges of the allocation and into the middle. This provides some protection against small-sized neighboring overflows (or underflows), for which the freelist pointer is commonly the target. (Large or well controlled overwrites are much more likely to attack live object contents, instead of attempting freelist corruption.) The vaunted kernel build benchmark, across 5 runs. Before: Mean: 250.05 Std Dev: 1.85 and after, which appears mysteriously faster: Mean: 247.13 Std Dev: 0.76 Attempts at running "sysbench --test=memory" show the change to be well in the noise (sysbench seems to be pretty unstable here -- it's not really measuring allocation). Hackbench is more allocation-heavy, and while the std dev is above the difference, it looks like may manifest as an improvement as well: 20 runs of "hackbench -g 20 -l 1000", before: Mean: 36.322 Std Dev: 0.577 and after: Mean: 36.056 Std Dev: 0.598 [1] https://twitter.com/vnik5287/status/1235113523098685440 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Acked-by: Christoph Lameter <cl@linux.com> Cc: Vitaly Nikolenko <vnik@duasynt.com> Cc: Silvio Cesare <silvio.cesare@gmail.com> Cc: Christoph Lameter <cl@linux.com>Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Link: http://lkml.kernel.org/r/202003051624.AAAC9AECC@keescook Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

slub: improve bit diffusion for freelist ptr obfuscation
Under CONFIG_SLAB_FREELIST_HARDENED=y, the obfuscation was relatively weak
in that the ptr and ptr address were usually so close that the first XOR
would result in an almost entirely 0-byte value[1], leaving most of the
"secret" number ultimately being stored after the third XOR. A single
blind memory content exposure of the freelist was generally sufficient to
learn the secret.
Add a swab() call to mix bits a little more. This is a cheap way (1
cycle) to make attacks need more than a single exposure to learn the
secret (or to know _where_ the exposure is in memory).
kmalloc-32 freelist walk, before:

ocfs2: roll back the reference count modification of the parent directory if an error occurs
Under some conditions, the directory cannot be deleted. The specific scenarios are as follows: (for example, /mnt/ocfs2 is the mount point) 1. Create the /mnt/ocfs2/p_dir directory. At this time, the i_nlink corresponding to the inode of the /mnt/ocfs2/p_dir directory is equal to 2. 2. During the process of creating the /mnt/ocfs2/p_dir/s_dir directory, if the call to the inc_nlink function in ocfs2_mknod succeeds, the functions such as ocfs2_init_acl, ocfs2_init_security_set, and ocfs2_dentry_attach_lock fail. At this time, the i_nlink corresponding to the inode of the /mnt/ocfs2/p_dir directory is equal to 3, but /mnt/ocfs2/p_dir/s_dir is not added to the /mnt/ocfs2/p_dir directory entry. 3. Delete the /mnt/ocfs2/p_dir directory (rm -rf /mnt/ocfs2/p_dir). At this time, it is found that the i_nlink corresponding to the inode corresponding to the /mnt/ocfs2/p_dir directory is equal to 3.

introduced in C99:
struct foo {

struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning in
case the flexible array does not occur last in the structure, which will
help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by this
change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

asm-generic: make more kernel-space headers mandatory
Change a header to mandatory-y if both of the following are met:
[1] At least one architecture (except um) specifies it as generic-y in
arch/*/include/asm/Kbuild
[2] Every architecture (except um) either has its own implementation
(arch/*/include/asm/*.h) or specifies it as generic-y in
arch/*/include/asm/Kbuild
This commit was generated by the following shell script.
----------------------------------->8-----------------------------------
arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d')
tmpfile=$(mktemp)
grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile
find arch -path 'arch/*/include/asm/Kbuild' |
xargs sed -n 's/^generic-y += \(.*\)/\1/p' | sort -u |
while read header
do
mandatory=yes
for arch in $arches
do
if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild &&
! [ -f arch/$arch/include/asm/$header ]; then
mandatory=no
break
fi
done
if [ "$mandatory" = yes ]; then
echo "mandatory-y += $header" >> $tmpfile
for arch in $arches
do
sed -i "/generic-y += $header/d" arch/$arch/include/asm/Kbuild
done
fi
done
sed -i '/^mandatory-y +=/d' include/asm-generic/Kbuild
LANG=C sort $tmpfile >> include/asm-generic/Kbuild
----------------------------------->8-----------------------------------
One obvious benefit is the diff stat:
25 files changed, 52 insertions(+), 557 deletions(-)
It is tedious to list generic-y for each arch that needs it.
So, mandatory-y works like a fallback default (by just wrapping
asm-generic one) when arch does not have a specific header
implementation.

kthread: mark timer used by delayed kthread works as IRQ safe
The timer used by delayed kthread works are IRQ safe because the used kthread_delayed_work_timer_fn() is IRQ safe. It is properly marked when initialized by KTHREAD_DELAYED_WORK_INIT(). But TIMER_IRQSAFE flag is missing when initialized by kthread_init_delayed_work(). The missing flag might trigger invalid warning from del_timer_sync() when kthread_mod_delayed_work() is called with interrupts disabled. This patch is result of a discussion about using the API, see https://lkml.kernel.org/r/cfa886ad-e3b7-c0d2-3ff8-58d94170eab5@ti.com Reported-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Petr Mladek <pmladek@suse.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Tested-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Tejun Heo <tj@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20200217120709.1974-1-pmladek@suse.com Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Kbuild updates for v5.7
[Build system]
- add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define
a fixed set of export symbols for Generic Kernel Image (GKI)
- allow to run 'make dt_binding_check' without .config
- use full schema for checking DT examples in *.yaml files
- make modpost fail for missing MODULE_IMPORT_NS(), which makes more
sense because we know the produced modules are never loadable
- Remove unused 'AS' variable
[Kconfig]
- sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig files
- relax the 'imply' behavior so that symbols implied by y can become m
- make 'imply' obey 'depends on' in order to make 'imply' really weak
[Misc]
- add documentation on building the kernel with Clang/LLVM
- revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen()
- fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n
- various script and Makefile cleanups

Pull SELinux updates from Paul Moore:
"We've got twenty SELinux patches for the v5.7 merge window, the
highlights are below:
- Deprecate setting /sys/fs/selinux/checkreqprot to 1.
This flag was originally created to deal with legacy userspace and
the READ_IMPLIES_EXEC personality flag. We changed the default from
1 to 0 back in Linux v4.4 and now we are taking the next step of
deprecating it, at some point in the future we will take the final
step of rejecting 1.
- Allow kernfs symlinks to inherit the SELinux label of the parent
directory. In order to preserve backwards compatibility this is
protected by the genfs_seclabel_symlinks SELinux policy capability.
- Optimize how we store filename transitions in the kernel, resulting
in some significant improvements to policy load times.
- Do a better job calculating our internal hash table sizes which
resulted in additional policy load improvements and likely general
SELinux performance improvements as well.
- Remove the unused initial SIDs (labels) and improve how we handle
initial SIDs.
- Enable per-file labeling for the bpf filesystem.
- Ensure that we properly label NFS v4.2 filesystems to avoid a
temporary unlabeled condition.
- Add some missing XFS quota command types to the SELinux quota
access controls.
- Fix a problem where we were not updating the seq_file position
index correctly in selinuxfs.
- We consolidate some duplicated code into helper functions.
- A number of list to array conversions.
- Update Stephen Smalley's email address in MAINTAINERS"

"We've got two audit patches for the v5.7 merge window with a stellar
14 lines changed between the two patches. The patch descriptions are
far more lengthy than the patches themselves, which is a very good
thing for patches this size IMHO. The patches pass our test suites and
a quick summary is below:
- Stop logging inode information when updating an audit file watch.
Since we are not changing the inode, or the fact that we are
watching the associated file, the inode information is just noise
that we can do without.
- Fix a problem where mandatory audit records were missing their
accompanying audit records (e.g. SYSCALL records were missing).
The missing records often meant that we didn't have the necessary
context to understand what was going on when the event occurred"

We've got a lot of patches (39) for this merge window. Most of these patches
are related to corruption that occurs when journals are replayed.
For example:
1. A node fails while writing to the file system.
2. Other nodes use the metadata that was once used by the failed node.
3. When the node returns to the cluster, its journal is replayed,
but the older metadata blocks overwrite the changes from step 2.
- Fixed the recovery sequence to prevent corruption during journal replay.
- Many bug fixes found during recovery testing.
- New improved file system withdraw sequence.
- Fixed how resource group buffers are managed.
- Fixed how metadata revokes are tracked and written.
- Improve processing of IO errors hit by daemons like logd and quotad.
- Improved error checking in metadata writes.

Merge tag 'gfs2-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 updates from Bob Peterson:
"We've got a lot of patches (39) for this merge window. Most of these
patches are related to corruption that occurs when journals are
replayed. For example:
1. A node fails while writing to the file system.
2. Other nodes use the metadata that was once used by the failed
node.
3. When the node returns to the cluster, its journal is replayed, but
the older metadata blocks overwrite the changes from step 2.
Summary:
- Fixed the recovery sequence to prevent corruption during journal
replay.
- Many bug fixes found during recovery testing.
- New improved file system withdraw sequence.
- Fixed how resource group buffers are managed.
- Fixed how metadata revokes are tracked and written.
- Improve processing of IO errors hit by daemons like logd and
quotad.
- Improved error checking in metadata writes.
- Fixed how qadata quota data structures are managed"

Pull btrfs updates from David Sterba:
"A number of core changes that make things work better in general, code
is simpler and cleaner.
Core changes:
- per-inode file extent tree, for in memory tracking of contiguous
extent ranges to make sure i_size adjustments are accurate
- tree root structures are protected by reference counts, replacing
SRCU that did not cover some cases
- leak detector for tree root structures
- per-transaction pinned extent tracking
- buffer heads are replaced by bios for super block access
- speedup of extent back reference resolution, on an example test
scenario the runtime of send went down from a hour to minutes
- factor out locking scheme used for subvolume writer and NOCOW
exclusion, abstracted as DREW lock, double reader-writer exclusion
(allow either readers or writers)
- cleanup and abstract extent allocation policies, preparation for
zoned device support
- make reflink/clone_range work on inline extents
- add more cancellation point for relocation, improves long response
from 'balance cancel'
- add page migration callback for data pages
- switch to guid for uuids, with additional cleanups of the interface
- make ranged full fsyncs more efficient
- removal of obsolete ioctl flag BTRFS_SUBVOL_CREATE_ASYNC
- remove b-tree readahead from delayed refs paths, avoiding seek and
read unnecessary blocks
Features:
- v2 of ioctl to delete subvolumes, allowing to delete by id and more
future extensions
Fixes:
- fix qgroup rescan worker that could block umount
- fix crash during unmount due to race with delayed inode workers
- fix dellaloc flushing logic that could create unnecessary chunks
under heavy load
- fix missing file extent item for hole after ranged fsync
- several fixes in relocation error handling
Other:
- more documentation of relocation, device replace, space
reservations
- many random cleanups"
