commit 40d8abf364bcab23bc715a9221a3c8623956257b upstream.
If the NumEntries field in the _CPC return package is less than 2, do
not attempt to access the "Revision" element of that package, because
it may not be present then.

commit 27ca8273fda398638ca994a207323a85b6d81190 upstream.
Per fstrim(8) we must round up the minlen argument to the fs block size.
The current calculation doesn't take into account devices that have a
discard granularity and requested minlen less than 1 fs block, so the
value can get shifted away to zero in the translation to fs blocks.
The zero minlen passed to gfs2_rgrp_send_discards() then allows
sb_issue_discard() to be called with nr_sects == 0 which returns -EINVAL
and results in gfs2_rgrp_send_discards() returning -EIO.
Make sure minlen is never < 1 fs block by taking the max of the
requested minlen and the fs block size before comparing to the device's
discard granularity and shifting to fs blocks.

commit 1b83ec057db16b4d0697dc21ef7a9743b6041f72 upstream.
Make 'ui->data_len' aligned with 8 bytes before it is assigned to
dirtied_ino_d. Since 8871d84c8f8b0c6b("ubifs: convert to fileattr")
applied, 'setflags()' only affects regular files and directories, only
xattr inode, symlink inode and special inode(pipe/char_dev/block_dev)
have none- zero 'ui->data_len' field, so assertion
'!(req->dirtied_ino_d & 7)' cannot fail in ubifs_budget_space().
To avoid assertion fails in future evolution(eg. setflags can operate
special inodes), it's better to make dirtied_ino_d 8 bytes aligned,
after all aligned size is still zero for regular files.

commit 5f6de5cbebee925a612856fce6f9182bb3eee0db upstream.
Tie the lifetime the KVM module to the lifetime of each VM via
kvm.users_count. This way anything that grabs a reference to the VM via
kvm_get_kvm() cannot accidentally outlive the KVM module.
Prior to this commit, the lifetime of the KVM module was tied to the
lifetime of /dev/kvm file descriptors, VM file descriptors, and vCPU
file descriptors by their respective file_operations "owner" field.
This approach is insufficient because references grabbed via
kvm_get_kvm() do not prevent closing any of the aforementioned file
descriptors.
This fixes a long standing theoretical bug in KVM that at least affects
async page faults. kvm_setup_async_pf() grabs a reference via
kvm_get_kvm(), and drops it in an asynchronous work callback. Nothing
prevents the VM file descriptor from being closed and the KVM module
from being unloaded before this callback runs.

[un]pin_user_pages_remote is dirtying pages without properly warning
the file system in advance. A related race was noted by Jan Kara in
2018[1]; however, more recently instead of it being a very hard-to-hit
race, it could be reliably triggered by process_vm_writev(2) which was
discovered by Syzbot[2].
This is technically a bug in mm/gup.c, but arguably ext4 is fragile in
that if some other kernel subsystem dirty pages without properly
notifying the file system using page_mkwrite(), ext4 will BUG, while
other file systems will not BUG (although data will still be lost).
So instead of crashing with a BUG, issue a warning (since there may be
potential data loss) and just mark the page as clean to avoid
unprivileged denial of service attacks until the problem can be
properly fixed. More discussion and background can be found in the
thread starting at [2].

Platforms with large BERT table data can trigger soft lockup errors
while attempting to print the entire BERT table data to the console at
boot:
watchdog: BUG: soft lockup - CPU#160 stuck for 23s! [swapper/0:1]
Observed on Ampere Altra systems with a single BERT record of ~250KB.
The original bert driver appears to have assumed relatively small table
data. Since it is impractical to reassemble large table data from
interwoven console messages, and the table data is available in
/sys/firmware/acpi/tables/data/BERT
limit the size for tables printed to the console to 1024 (for no reason
other than it seemed like a good place to kick off the discussion, would
appreciate feedback from existing users in terms of what size would
maintain their current usage model).
Alternatively, we could make printing a CONFIG option, use the
bert_disable boot arg (or something similar), or use a debug log level.
However, all those solutions require extra steps or change the existing
behavior for small table data. Limiting the size preserves existing
behavior on existing platforms with small table data, and eliminates the
soft lockups for platforms with large table data, while still making it
available.

... | x25->neighbour->extended //(2)
The code sets NULL to x25->neighbour in position (1) and dereferences
x25->neighbour in position (2), which could cause null-ptr-deref bug.
This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize
with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the
sock held by lock_sock() is not NULL, because it is extracted from x25_list
and uses x25_list_lock to synchronize.

[ Upstream commit bf8bfc4336f7a34e48b3bbd19b1542bf085bdc3d ]
A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
Broadcom UniMAC MDIO controller as not completing the turn around
properly since the PHY expects 65 MDC clock cycles to complete a write
cycle, and the MDIO controller was only sending 64 MDC clock cycles as
determined by looking at a scope shot.
This would make the subsequent read fail with the UniMAC MDIO controller
command field having MDIO_READ_FAIL set and we would abort the
brcm_fet_config_init() function and thus not probe the PHY at all.
After issuing a software reset, wait for at least 1ms which is well
above the 1us reset delay advertised by the datasheet and issue a dummy
read to let the PHY turn around the line properly. This read
specifically ignores -EIO which would be returned by MDIO controllers
checking for the line being turned around.
If we have a genuine reaad failure, the next read of the interrupt
status register would pick it up anyway.

Syzbot crafted an image with bmp->db_numag equal to 0. There wasn't any

expression
Fix it by validating bmp->db_numag in dbMount() and return an error if
