[ Upstream commit f81c08f897adafd2ed43f86f00207ff929f0b2eb ]
testusb' application which uses 'usbtest' driver reports 'unknown speed'
from the function 'find_testdev'. The variable 'entry->speed' was not
updated from the application. The IOCTL mentioned in the FIXME comment can
only report whether the connection is low speed or not. Speed is read using
the IOCTL USBDEVFS_GET_SPEED which reports the proper speed grade. The
call is implemented in the function 'handle_testdev' where the file
descriptor was availble locally. Sample output is given below where 'high
speed' is printed as the connected speed.

2.33.0
From: Kate Hsuan <[email protected]>
commit 7a8526a5cd51cf5f070310c6c37dd7293334ac49 upstream.
Many users are reporting that the Samsung 860 and 870 SSD are having
various issues when combined with AMD/ATI (vendor ID 0x1002) SATA
controllers and only completely disabling NCQ helps to avoid these
issues.
Always disabling NCQ for Samsung 860/870 SSDs regardless of the host
SATA adapter vendor will cause I/O performance degradation with well
behaved adapters. To limit the performance impact to ATI adapters,
introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ
only for these adapters.
Also, two libata.force parameters (noncqati and ncqati) are introduced
to disable and enable the NCQ for the system which equipped with ATI
SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ
function to be enabled or disabled according to the demand.
After verifying the chipset from the user reports, the issue appears
on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on
recent AMD SATA adapters. The vendor ID of ATI should be 0x1002.
Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to
ATA_HORKAGE_NO_NCQ_ON_ATI.

commit 35306eb23814444bd4021f8a1c3047d3cb0c8b2b upstream.
Jann Horn reported that SO_PEERCRED and SO_PEERGROUPS implementations
are racy, as af_unix can concurrently change sk_peer_pid and sk_peer_cred.
In order to fix this issue, this patch adds a new spinlock that needs
to be used whenever these fields are read or written.
Jann also pointed out that l2cap_sock_get_peer_pid_cb() is currently
reading sk->sk_peer_pid which makes no sense, as this field
is only possibly set by AF_UNIX sockets.
We will have to clean this in a separate patch.
This could be done by reverting b48596d1dc25 "Bluetooth: L2CAP: Add get_peer_pid callback"
or implementing what was truly expected.
Fixes: 109f6e39fa07 ("af_unix: Allow SO_PEERCRED to work across namespaces.")

[ Upstream commit 372d1f3e1bfede719864d0d1fbf3146b1e638c88 ]
The ext2_error() function syncs the filesystem so it sleeps. The caller
is holding a spinlock so it's not allowed to sleep.
ext2_statfs() <- disables preempt
-> ext2_count_free_blocks()
-> ext2_get_group_desc()
Fix this by using WARN() to print an error message and a stack trace
instead of using ext2_error().
