2022-03-27s390/unwind: recover kretprobe modified return address in stacktraceVasily Gorbik2-6/+15
Based on commit cd9bc2c92588 ("arm64: Recover kretprobe modified return address in stacktrace"). """ Since the kretprobe replaces the function return address with the __kretprobe_trampoline on the stack, stack unwinder shows it instead of the correct return address. This checks whether the next return address is the __kretprobe_trampoline(), and if so, try to find the correct return address from the kretprobe instance list.

The driver currently uses a CPU family match of 17h to determine EFCH_PM_DECODEEN_WDT_TMREN register support. This family check will not support future AMD CPUs and instead will require driver updates to add support. Remove the family 17h family check and add a check for SMBus PCI revision ID 0x51 or greater. The MMIO access method has been available since at least SMBus controllers using PCI revision 0x51.

2022-03-27watchdog: imx2_wdg: Alow ping on suspendAlistair Francis1-7/+20
The i.MX watchdog cannot be disabled by software once it has been enabled. This means that it can't be stopped before suspend. For systems that enter low power mode this is fine, as the watchdog will be automatically stopped by hardware in low power mode. Not all i.MX platforms support low power mode in the mainline kernel. For example the i.MX7D does not enter low power mode and so will be rebooted 2 minutes after entering sleep states. This patch introduces a device tree property "fsl,ping-during-suspend" that can be used to enable ping on suspend support for these systems.

The bug is here: err = snd_card_cs423x_pnp(dev, card->private_data, pdev, cdev); The list iterator value 'cdev' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found. To fix the bug, use a new variable 'iter' as the list iterator, while use the original variable 'cdev' as a dedicated pointer to point to the found element. And snd_card_cs423x_pnp() itself has NULL check for cdev.

Pull NVMe write streams removal from Jens Axboe: "This removes the write streams support in NVMe. No vendor ever really shipped working support for this, and they are not interested in supporting it. With the NVMe support gone, we have nothing in the tree that supports this. Remove passing around of the hints. The only discussion point in this patchset imho is the fact that the file specific write hint setting/getting fcntl helpers will now return -1/EINVAL like they did before we supported write hints. No known applications use these functions, I only know of one prototype that I help do for RocksDB, and that's not used. That said, with a change like this, it's always a bit controversial. Alternatively, we could just make them return 0 and pretend it worked. It's placement based hints after all" * tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block: fs: remove fs.f_write_hint fs: remove kiocb.ki_hint block: remove the per-bio/request write hint nvme: remove support or stream based temperature hint
2022-03-26net: sparx5: switchdev: fix possible NULL pointer dereferenceZheng Yongjun1-0/+2
As the possible failure of the allocation, devm_kzalloc() may return NULL pointer. Therefore, it should be better to check the 'db' in order to prevent the dereference of NULL pointer.

2022-03-26net/x25: Fix null-ptr-deref caused by x25_disconnectDuoming Zhou1-3/+8
When the link layer is terminating, x25->neighbour will be set to NULL in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is shown below. (Thread 1) | (Thread 2) x25_link_terminated() | x25_recvmsg() x25_kill_by_neigh() | ... x25_disconnect() | lock_sock(sk) ... | ... x25->neighbour = NULL //(1) | ... | 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.
