[ Upstream commit 2f6d721e14 ]
When a file only needs one direct_node, performing the following
operations will cause the file to be unrepairable:
unisoc # ./f2fs_io compress test.apk
unisoc #df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.2M 100% /data
unisoc # ./f2fs_io release_cblocks test.apk

unisoc # dd if=/dev/random of=file4 bs=1M count=3
3145728 bytes (3.0 M) copied, 0.025 s, 120 M/s
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.8M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk
F2FS_IOC_RESERVE_COMPRESS_BLOCKS failed: No space left on device
adb reboot
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 11M 100% /data
unisoc # ./f2fs_io reserve_cblocks test.apk
0
This is because the file has only one direct_node. After returning
to -ENOSPC, reserved_blocks += ret will not be executed. As a result,
the reserved_blocks at this time is still 0, which is not the real
number of reserved blocks. Therefore, fsck cannot be set to repair
the file.
After this patch, the fsck flag will be set to fix this problem.
unisoc # df -h | grep dm-48
/dev/block/dm-48 112G 112G 1.8M 100% /data

[ Upstream commit a35518cae4 ]
Currently, even though xprtsec=tls is specified and used for operations
to MDS, any operations that go to DS travel over unencrypted connection.
Or additionally, if more than 1 DS can serve the data, then trunked
connections are also done unencrypted.
IN GETDEVINCEINFO, we get an entry for the DS which carries a protocol
type (which is TCP), then nfs4_set_ds_client() gets called with TCP
instead of TCP with TLS.
Currently, each trunked connection is created and uses clp->cl_hostname
value which if TLS is used would get passed up in the handshake upcall,
but instead we need to pass in the appropriate trunked address value.

[ Upstream commit fd5860ab63 ]
The loop inside nfs_netfs_issue_read() currently does not disable
interrupts while iterating through pages in the xarray to submit
for NFS read. This is not safe though since after taking xa_lock,
another page in the mapping could be processed for writeback inside
an interrupt, and deadlock can occur. The fix is simple and clean
if we use xa_for_each_range(), which handles the iteration with RCU
while reducing code complexity.
The problem is easily reproduced with the following test:
mount -o vers=3,fsc 127.0.0.1:/export /mnt/nfs
dd if=/dev/zero of=/mnt/nfs/file1.bin bs=4096 count=1
echo 3 > /proc/sys/vm/drop_caches
dd if=/mnt/nfs/file1.bin of=/dev/null
umount /mnt/nfs
On the console with a lockdep-enabled kernel a message similar to
the following will be seen:

[ Upstream commit dbd7c0088b ]
The driver never sets a default timeout value, therefore it is
initialized to zero. When CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED is
enabled, the watchdog is started during probe. The kernel is supposed to
automatically ping the watchdog from this point until userspace takes
over, but this does not happen if the configured timeout is zero. A zero
timeout causes watchdog_need_worker() to return false, so the heartbeat
worker does not run and the system therefore resets soon after the
driver is probed.
This patch fixes this by setting an arbitrary non-zero default timeout.
The default could be read from the hardware instead, but I didn't see
any reason to add this complexity.
This has been tested on an STM32F746.

Switch order of operations to avoid creating a short XDR buffer:
e.g., buflen = 12, old xdrlen = 12, new xdrlen = 20.
Having a short XDR buffer leads to lxa_maxcount be a few bytes
less than what is needed to retrieve the whole list when using
a buflen as returned by a call with size = 0:
buflen = listxattr(path, NULL, 0);
buf = malloc(buflen);
buflen = listxattr(path, buf, buflen);
For a file with one attribute (name = '123456'), the first call
with size = 0 will return buflen = 12 ('user.123456\x00').
The second call with size = 12, sends LISTXATTRS with
lxa_maxcount = 12 + 8 (cookie) + 4 (array count) = 24. The
XDR buffer needs 8 (cookie) + 4 (array count) + 4 (name count)
+ 6 (name len) + 2 (padding) + 4 (eof) = 28 which is 4 bytes
shorter than the lxa_maxcount provided in the call.

Assuming the code is actually correct here and the callers always match the

a union of the two pointer types. This does not change the behavior of the

necessary.

[ Upstream commit 21ec682348 ]
During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.
Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.
Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.

It is possible that other threads have added this fio to io->bio

At this point io->bio = NULL.
If is_end_zone_blkaddr(sbi, fio->new_blkaddr) of this fio is true,
then an NULL pointer dereference error occurs at bio_get(io->bio).
The original code for determining zone end was after "out:",
which would have missed some fio who is zone end. I've moved
this code before "skip:" to make sure it's done for each fio.

Realtek codec on HP Envy laptop series are heavily modified by vendor.
Therefore, need intervention to make it work properly. The patch fixes:
- B&O soundbar speakers (between lid and keyboard) activation
- Enable LED on mute button
- Add missing process coefficient which affects the output amplifier
- Volume control synchronization between B&O soundbar and side speakers
- Unmute headset output on several HP Envy models
- Auto-enable headset mic when plugged
This patch was tested on HP Envy x360 13-AR0107AU with Realtek ALC285
The only unsolved problem is output amplifier of all built-in speakers
is too weak, which causes volume of built-in speakers cannot be loud
as vendor's proprietary driver due to missing _DSD parameter in the
firmware. The solution is currently on research. Expected to has another
patch in the future.

[ Upstream commit f3dc1bdb6b ]
cifs writeback doesn't correctly handle the case where
cifs_extend_writeback() hits a point where it is considering an additional
folio, but this would overrun the wsize - at which point it drops out of
the xarray scanning loop and calls xas_pause(). The problem is that
xas_pause() advances the loop counter - thereby skipping that page.
What needs to happen is for xas_reset() to be called any time we decide we
don't want to process the page we're looking at, but rather send the
request we are building and start a new one.
Fix this by copying and adapting the netfslib writepages code as a
temporary measure, with cifs writeback intending to be offloaded to
netfslib in the near future.
This also fixes the issue with the use of filemap_get_folios_tag() causing
retry of a bunch of pages which the extender already dealt with.
This can be tested by creating, say, a 64K file somewhere not on cifs
(otherwise copy-offload may get underfoot), mounting a cifs share with a
wsize of 64000, copying the file to it and then comparing the original file
and the copy:
dd if=/dev/urandom of=/tmp/64K bs=64k count=1
mount //192.168.6.1/test /mnt -o user=...,pass=...,wsize=64000
cp /tmp/64K /mnt/64K
cmp /tmp/64K /mnt/64K
Without the fix, the cmp fails at position 64000 (or shortly thereafter).
