[PATCH AUTOSEL 4.19 02/21] HID: quirks: Set INCREMENT_USAGE_ON_DUPLICATE for Saitek X65

[Sasha Levin]

From: Nirenjan Krishnan <nirenjan@gmail.com>

[ Upstream commit 25bdbfbb2d8331a67824dd03d0087e9c98835f3a ]

The Saitek X65 joystick has a pair of axes that were used as mouse
pointer controls by the Windows driver. The corresponding usage page is
the Game Controls page, which is not recognized by the generic HID
driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes
the second axis get mapped to ABS_MISC+1, and therefore made available
separately.

[PATCH AUTOSEL 4.19 05/21] HID: usbhid: fix info leak in hid_submit_ctrl

[Sasha Levin]

From: Anirudh Rayabharam <mail@anirudhrb.com>

[ Upstream commit 6be388f4a35d2ce5ef7dbf635a8964a5da7f799f ]

In hid_submit_ctrl(), the way of calculating the report length doesn't
take into account that report->size can be zero. When running the
syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to
calculate transfer_buffer_length as 16384. When this urb is passed to
the usb core layer, KMSAN reports an info leak of 16384 bytes.

To fix this, first modify hid_report_len() to account for the zero
report size case by using DIV_ROUND_UP for the division. Then, call it
from hid_submit_ctrl().

[PATCH AUTOSEL 4.19 09/21] gfs2: Fix use-after-free in gfs2_glock_shrink_scan

[Sasha Levin]

From: Hillf Danton <hdanton@sina.com>

[ Upstream commit 1ab19c5de4c537ec0d9b21020395a5b5a6c059b2 ]

The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to
remove the glock from the lru list in __gfs2_glock_put().

On the shrink scan path, the same flag is cleared under lru_lock but because
of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the
put side can be made without deleting the glock from the lru list.

Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to
ensure correct behavior on both sides - clear GLF_LRU after list_del under
lru_lock.

From: Hillf Danton <hdanton@sina.com>

[ Upstream commit 1ab19c5de4c537ec0d9b21020395a5b5a6c059b2 ]

The GLF_LRU flag is checked under lru_lock in gfs2_glock_remove_from_lru() to
remove the glock from the lru list in __gfs2_glock_put().

On the shrink scan path, the same flag is cleared under lru_lock but because
of cond_resched_lock(&lru_lock) in gfs2_dispose_glock_lru(), progress on the
put side can be made without deleting the glock from the lru list.

Keep GLF_LRU across the race window opened by cond_resched_lock(&lru_lock) to
ensure correct behavior on both sides - clear GLF_LRU after list_del under
lru_lock.

[PATCH AUTOSEL 4.19 10/21] Bluetooth: use correct lock to prevent UAF of hdev object

[Sasha Levin]

From: Lin Ma <linma@zju.edu.cn>

[ Upstream commit e305509e678b3a4af2b3cfd410f409f7cdaabb52 ]

The hci_sock_dev_event() function will cleanup the hdev object for
sockets even if this object may still be in used within the
hci_sock_bound_ioctl() function, result in UAF vulnerability.

This patch replace the BH context lock to serialize these affairs
and prevent the race condition.

[PATCH AUTOSEL 4.19 11/21] scsi: target: core: Fix warning on realtime kernels

[Sasha Levin]

From: Maurizio Lombardi <mlombard@redhat.com>

[ Upstream commit 515da6f4295c2c42b8c54572cce3d2dd1167c41e ]

On realtime kernels, spin_lock_irq*(spinlock_t) do not disable the
interrupts, a call to irqs_disabled() will return false thus firing a
warning in __transport_wait_for_tasks().

Remove the warning and also replace assert_spin_locked() with
lockdep_assert_held()

[PATCH AUTOSEL 4.19 17/21] net: ipconfig: Don't override command-line hostnames or domains

From: Josh Triplett <josh@joshtriplett.org>

[ Upstream commit b508d5fb69c2211a1b860fc058aafbefc3b3c3cd ]

If the user specifies a hostname or domain name as part of the ip=
command-line option, preserve it and don't overwrite it with one
supplied by DHCP/BOOTP.

For instance, ip=::::myhostname::dhcp will use "myhostname" rather than
ignoring and overwriting it.

Fix the comment on ic_bootp_string that suggests it only copies a string
"if not already set"; it doesn't have any such logic.

[PATCH AUTOSEL 4.19 20/21] net: Return the correct errno code

[ Upstream commit 49251cd00228a3c983651f6bb2f33f6a0b8f152e ]

When kalloc or kmemdup failed, should return ENOMEM rather than ENOBUF.
