mailmap: update Gao Xiang's email addresses
I've been in Alibaba Cloud for more than one year, mainly to address cloud-native challenges (such as high-performance container images) for open source communities. Update my email addresses on behalf of my current employer (Alibaba Cloud) to support all my (team) work in this area. Also add an outdated @redhat.com address of me.

hugetlb: fix memoryleak in hugetlb_mcopy_atomic_pte
When alloc_huge_page fails, *pagep is set to NULL without put_page first.
So the hugepage indicated by *pagep is leaked.

fs: sendfile handles O_NONBLOCK of out_fd
sendfile has to return EAGAIN if out_fd is nonblocking and the write into
it would block.
Here is a small reproducer for the problem:
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
#include <errno.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <sys/sendfile.h>
#define FILE_SIZE (1UL << 30)
int main(int argc, char **argv) {
int p[2], fd;
if (pipe2(p, O_NONBLOCK))
return 1;
fd = open(argv[1], O_RDWR | O_TMPFILE, 0666);
if (fd < 0)
return 1;
ftruncate(fd, FILE_SIZE);
if (sendfile(p[1], fd, 0, FILE_SIZE) == -1) {
fprintf(stderr, "FAIL\n");
}
if (sendfile(p[1], fd, 0, FILE_SIZE) != -1 || errno != EAGAIN) {
fprintf(stderr, "FAIL\n");
}
return 0;
}
It worked before

mm/hugetlb: separate path for hwpoison entry in copy_hugetlb_page_range()
Originally copy_hugetlb_page_range() handles migration entries and
hwpoisoned entries in similar manner. But recently the related code path
has more code for migration entries, and when
is_writable_migration_entry() was converted to
!is_readable_migration_entry(), hwpoison entries on source processes got
to be unexpectedly updated (which is legitimate for migration entries, but
not for hwpoison entries). This results in unexpected serious issues like
kernel panic when forking processes with hwpoison entries in pmd.
Separate the if branch into one for hwpoison entries and one for migration
entries.

mm: fix missing wake-up event for FSDAX pages
FSDAX page refcounts are 1-based, rather than 0-based: if refcount is
1, then the page is freed. The FSDAX pages can be pinned through GUP,
then they will be unpinned via unpin_user_page() using a folio variant
to put the page, however, folio variants did not consider this special
case, the result will be to miss a wakeup event (like the user of
__fuse_dax_break_layouts()). This results in a task being permanently
stuck in TASK_INTERRUPTIBLE state.
Since FSDAX pages are only possibly obtained by GUP users, so fix GUP
instead of folio_put() to lower overhead.

mm: fix page leak with multiple threads mapping the same page
We have an application with a lot of threads that use a shared mmap backed by tmpfs mounted with -o huge=within_size. This application started leaking loads of huge pages when we upgraded to a recent kernel. Using the page ref tracepoints and a BPF program written by Tejun Heo we were able to determine that these pages would have multiple refcounts from the page fault path, but when it came to unmap time we wouldn't drop the number of refs we had added from the faults. I wrote a reproducer that mmap'ed a file backed by tmpfs with -o huge=always, and then spawned 20 threads all looping faulting random offsets in this map, while using madvise(MADV_DONTNEED) randomly for huge page aligned ranges. This very quickly reproduced the problem. The problem here is that we check for the case that we have multiple threads faulting in a range that was previously unmapped. One thread maps the PMD, the other thread loses the race and then returns 0. However at this point we already have the page, and we are no longer putting this page into the processes address space, and so we leak the page. We actually did the correct thing prior to |

mm: kfence: apply kmemleak_ignore_phys on early allocated pool
This patch solves two issues.
(1) The pool allocated by memblock needs to unregister from
kmemleak scanning. Apply kmemleak_ignore_phys to replace the
original kmemleak_free as its address now is stored in the phys tree.
(2) The pool late allocated by page-alloc doesn't need to unregister.
Move out the freeing operation from its call path.

mm: split huge PUD on wp_huge_pud fallback
Currently the implementation will split the PUD when a fallback is taken
inside the create_huge_pud function. This isn't where it should be done:
the splitting should be done in wp_huge_pud, just like it's done for PMDs.
Reason being that if a callback is taken during create, there is no PUD
yet so nothing to split, whereas if a fallback is taken when encountering
a write protection fault there is something to split.
It looks like this was the original intention with the commit where the
splitting was introduced, but somehow it got moved to the wrong place
between v1 and v2 of the patch series. Rebase mistake perhaps.

mm/rmap: fix dereferencing invalid subpage pointer in try_to_migrate_one()
The subpage we calculate is an invalid pointer for device private pages,
because device private pages are mapped via non-present device private
entries, not ordinary present PTEs.
Let's just not compute broken pointers and fixup later. Move the proper
assignment of the correct subpage to the beginning of the function and
assert that we really only have a single page in our folio.
This currently results in a BUG when tying to compute anon_exclusive,

mm: sparsemem: fix missing higher order allocation splitting
Higher order allocations for vmemmap pages from buddy allocator must be
able to be treated as indepdenent small pages as they can be freed
individually by the caller. There is no problem for higher order vmemmap
pages allocated at boot time since each individual small page will be
initialized at boot time. However, it will be an issue for memory hotplug
case since those higher order vmemmap pages are allocated from buddy
allocator without initializing each individual small page's refcount. The
system will panic in put_page_testzero() when CONFIG_DEBUG_VM is enabled
if the vmemmap page is freed.

mm: userfaultfd: fix UFFDIO_CONTINUE on fallocated shmem pages
When fallocate() is used on a shmem file, the pages we allocate can end up
with !PageUptodate.
Since UFFDIO_CONTINUE tries to find the existing page the user wants to
map with SGP_READ, we would fail to find such a page, since
shmem_getpage_gfp returns with a "NULL" pagep for SGP_READ if it discovers
!PageUptodate. As a result, UFFDIO_CONTINUE returns -EFAULT, as it would
do if the page wasn't found in the page cache at all.
This isn't the intended behavior. UFFDIO_CONTINUE is just trying to find
if a page exists, and doesn't care whether it still needs to be cleared or
not. So, instead of SGP_READ, pass in SGP_NOALLOC. This is the same,
except for one critical difference: in the !PageUptodate case, SGP_NOALLOC
will clear the page and then return it. With this change, UFFDIO_CONTINUE
works properly (succeeds) on a shmem file which has been fallocated, but
otherwise not modified.

- A fix for a CMA change that broke booting guests with > 2G RAM on Power8 hosts.
- Fix the RTAS call filter to allow a special case that applications rely on.
- A change to our execve path, to make the execve syscall exit tracepoint work.
- Three fixes to wire up our various RNGs earlier in boot so they're available for use in
the initial seeding in random_init().
- A build fix for when KASAN is enabled along with STRUCTLEAK_BYREF_ALL.

Pull cifs client fixes from Steve French:
"Fixes addressing important multichannel, and reconnect issues.
Multichannel mounts when the server network interfaces changed, or ip
addresses changed, uncovered problems, especially in reconnect, but
the patches for this were held up until recently due to some lock
conflicts that are now addressed.
Included in this set of fixes:
- three fixes relating to multichannel reconnect, dynamically
adjusting the list of server interfaces to avoid problems during
reconnect
- a lock conflict fix related to the above
- two important fixes for negotiate on secondary channels (null
netname can unintentionally cause multichannel to be disabled to
some servers)
- a reconnect fix (reporting incorrect IP address in some cases)"

perf inject: Adjust output data offset for backward compatibility
When 'perf inject' creates a new file, it reuses the data offset from the input file. If there has been a change on the size of the header, as happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in a corrupted output file. This change adds the function perf_session__data_offset to compute the data offset based on the current header size, and uses that instead of the offset from the original input file.

perf build-id: Fix caching files with a wrong build ID
Build ID events associate a file name with a build ID. However, when
using perf inject, there is no guarantee that the file on the current
machine at the current time has that build ID. Fix by comparing the
build IDs and skip adding to the cache if they are different.
Example:
$ echo "int main() {return 0;}" > prog.c
$ gcc -o prog prog.c
$ perf record --buildid-all ./prog
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.019 MB perf.data ]
$ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; }
$ file-buildid prog
444ad9be165d8058a48ce2ffb4e9f55854a3293e
$ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
444ad9be165d8058a48ce2ffb4e9f55854a3293e
$ echo "int main() {return 1;}" > prog.c
$ gcc -o prog prog.c
$ file-buildid prog
885524d5aaa24008a3e2b06caa3ea95d013c0fc5
Before:
$ perf buildid-cache --purge $(pwd)/prog
$ perf inject -i perf.data -o junk
$ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf
885524d5aaa24008a3e2b06caa3ea95d013c0fc5

parisc: Fix flush_anon_page on PA8800/PA8900
Anonymous pages are allocated with the shared mappings colouring, SHM_COLOUR. Since the alias boundary on machines with PA8800 and PA8900 processors is unknown, flush_user_cache_page() might not flush all mappings of a shared anonymous page. Flushing the whole data cache flushes all mappings. This won't fix all coherency issues with shared mappings but it seems to work well in practice. I haven't seen any random memory faults in almost a month on a rp3440 running as a debian buildd machine. There is a small preformance hit.

IIO driver fixes for 5.19-rc4
Here are a set of IIO driver fixes for 5.19-rc4. Jonathan said it best
in his pull request to me, so I'll just quote it here below, as that's
the only changes we have right now for the char-misc driver tree:
1st set of IIO fixes for the 5.19 cycle.
Most of these have been in next for a long time. Unfortunately there
was one stray patch in the branch (wasn't a fix), so I've just rebased
to remove that.
* testing
- Fix a missing MODULE_LICENSE() warning by restricting possible build
configs.
* Various drivers
- Fix ordering of iio_get_trigger() being called before
iio_trigger_register()
* adi,admv1014
- Fix dubious x & !y warning.
* adi,axi-adc
- Fix missing of_node_put() in error and normal paths.
* aspeed,adc
- Add missing of_node_put()
* fsl,mma8452
- Fix broken probing from device tree.
- Drop check on return value of i2c write to device to cause reset as
ACK will be missing (device reset before sending it).
* fsl,vf610
- Fix documentation of in_conversion_mode ABI.
* iio-trig-sysfs
- Ensure irq work has finished before freeing the trigger.
* invensense,mpu3050
- Disable regulators in error path.
* invensense,icm42600
- Fix collision of enum value of 0 with error path where 0 is no match.
* renesas,rzg2l_Adc
- Add missing fwnode_handle_put() in error path.
* rescale
- Fix a boolean logic bug for detection of raw + scale affecting an
obscure corner case.
* semtech,sx9324
- Check return value of read of pin_defs
* st,stm32-adc:
- Fix interaction across ADC instances for some supported devices.
- Drop false spurious IRQ messages.
- Fix calibration value handling. If we can't calibrate don't expose the
vref_int channel.
- Fix maximum clock rate for stm32pm15x
* ti,ads131e08
- Add missing fwnode_handle_put() in error paths.
* xilinx,ams
- Fix variable checked for error from platform_get_irq()
* x-powers,axp288
- Overide TS_PIN bias current for boards where it is not correctly
initialized.
* yamaha,yas530
- Fix inverted check on calibration data being all zeros.
All of these have been in linux-next for a while with no reported
problems.
