2022-07-23watchdog: pm8916_wdt: Handle watchdog enabled by bootloaderStephan Gerhold
The bootloader might already enable the watchdog to catch hangs during the boot process. In that case the kernel needs to ping the watchdog temporarily until userspace is fully started. Add a check for this in the probe() function and set the WDOG_HW_RUNNING flag to make the watchdog core handle this automatically.

2022-07-23watchdog: pm8916_wdt: Report reboot reasonStephan Gerhold
The PM8916 PMIC provides "power-off reason" (POFF_REASON) registers to allow detecting why the board was powered off or rebooted. This can be used to expose if a reset happened due to a watchdog timeout. The watchdog API also provides status bits for overtemperature and undervoltage which happen to be reported in the same PMIC register. Make this information available as part of the watchdog device so userspace can decide to handle the situation accordingly.

2022-07-23watchdog: pm8916_wdt: Avoid read of write-only PET registerStephan Gerhold
PMIC_WD_RESET_PET is a write-only register that is used to ping the watchdog. It does not make sense to use read-modify-write for it: a register read will never return anything but zero. (And actually even if it did we would still want to write again to ensure the watchdog is pinged.) Reduce the overhead for the watchdog ping slightly by using regmap_write() directly instead.

2022-07-23watchdog: wdat_wdt: Remove #ifdef guards for PM related functionsPaul Cercueil
Use the new NOIRQ_SYSTEM_SLEEP_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. Not using #ifdef guards means that the code is always compiled independently of any Kconfig option, and thanks to that bugs and regressions are easier to catch.

2022-06-16dm mirror log: round up region bitmap size to BITS_PER_LONGMikulas Patocka
The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan.

2022-06-16dm: fix narrow race for REQ_NOWAIT bios being issued despite no supportMikulas Patocka
Starting with the commit 63a225c9fd20, device mapper has an optimization that it will take cheaper table lock (dm_get_live_table_fast instead of dm_get_live_table) if the bio has REQ_NOWAIT. The bios with REQ_NOWAIT must not block in the target request routine, if they did, we would be blocking while holding rcu_read_lock, which is prohibited. The targets that are suitable for REQ_NOWAIT optimization (and that don't block in the map routine) have the flag DM_TARGET_NOWAIT set. Device mapper will test if all the targets and all the devices in a table support nowait (see the function dm_table_supports_nowait) and it will set or clear the QUEUE_FLAG_NOWAIT flag on its request queue according to this check. There's a test in submit_bio_noacct: "if ((bio->bi_opf & REQ_NOWAIT) && !blk_queue_nowait(q)) goto not_supported" - this will make sure that REQ_NOWAIT bios can't enter a request queue that doesn't support them. This mechanism works to prevent REQ_NOWAIT bios from reaching dm targets that don't support the REQ_NOWAIT flag (and that may block in the map routine) - except that there is a small race condition: submit_bio_noacct checks if the queue has the QUEUE_FLAG_NOWAIT without holding any locks. Immediatelly after this check, the device mapper table may be reloaded with a table that doesn't support REQ_NOWAIT (for example, if we start moving the logical volume or if we activate a snapshot). However the REQ_NOWAIT bio that already passed the check in submit_bio_noacct would be sent to device mapper, where it could be redirected to a dm target that doesn't support REQ_NOWAIT - the result is sleeping while we hold rcu_read_lock. In order to fix this race, we double-check if the target supports REQ_NOWAIT while we hold the table lock (so that the table can't change under us).

2022-06-16dm: fix use-after-free in dm_put_live_table_bioMikulas Patocka
dm_put_live_table_bio is called from the end of dm_submit_bio. However, at this point, the bio may be already finished and the caller may have freed the bio. Consequently, dm_put_live_table_bio accesses the stale "bio" pointer. Fix this bug by loading the bi_opf value and passing it to dm_get_live_table_bio and dm_put_live_table_bio instead of the bio. This bug was found by running the lvm2 testsuite with kasan.

2022-06-15net: usb: ax88179_178a needs FLAG_SEND_ZLPJose Alonso
The extra byte inserted by usbnet.c when (length % dev->maxpacket == 0) is causing problems to device. This patch sets FLAG_SEND_ZLP to avoid this. Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet Problems observed: ====================================================================== 1) Using ssh/sshfs. The remote sshd daemon can abort with the message: "message authentication code incorrect" This happens because the tcp message sent is corrupted during the USB "Bulk out". The device calculate the tcp checksum and send a valid tcp message to the remote sshd. Then the encryption detects the error and aborts. 2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out 3) Stop normal work without any log message. The "Bulk in" continue receiving packets normally. The host sends "Bulk out" and the device responds with -ECONNRESET. (The netusb.c code tx_complete ignore -ECONNRESET) Under normal conditions these errors take days to happen and in intense usage take hours. A test with ping gives packet loss, showing that something is wrong: ping -4 -s 462 {destination} # 462 = 512 - 42 - 8 Not all packets fail. My guess is that the device tries to find another packet starting at the extra byte and will fail or not depending on the next bytes (old buffer content). ====================================================================== Signed-off-by: Jose Alonso <joalonsof@gmail.com> Signed-off-by: David S.
