These are indeed "should not happen" situations, but it turns out recent changes made the 'task_is_stopped_or_trace()' case trigger (fix for that exists, is pending more testing), and the BUG_ON() makes it unnecessarily hard to actually debug for no good reason. It's been that way for a long time, but let's make it clear: BUG_ON() is not good for debugging, and should never be used in situations where you could just say "this shouldn't happen, but we can continue". Use WARN_ON_ONCE() instead to make sure it gets logged, and then just continue running. Instead of making the system basically unusuable because you crashed the machine while potentially holding some very core locks (eg this function is commonly called while holding 'tasklist_lock' for writing).

The `vcsr` only exists in the old hardware design, it isn't used in any shipped hardware from Loongson-3A5000 on. Both scalar FP and LSX/LASX instructions use the `fcsr` as their control and status registers now. For example, the RM control bit in fcsr0 is shared by FP, LSX and LASX instructions. Particularly, fcsr16 to fcsr31 are reserved for LSX/LASX now, access to these registers has no visible effect if LSX/LASX is enabled, and will cause SXD/ASXD exceptions if LSX/LASX is not enabled. So, mentions of vcsr are obsolete in the first place (it was just used for debugging), let's remove them. Reviewed-by:

Commit fa96b57c ("LoongArch: Add build infrastructure") adds the new file arch/loongarch/Kconfig. As the work on LoongArch was probably quite some time under development, various config symbols have changed and disappeared from the time of initial writing of the Kconfig file and its inclusion in the repository. The following four commits: commit c126a53c ("arch: remove GENERIC_FIND_FIRST_BIT entirely") commit 140c8180 ("arch: remove HAVE_COPY_THREAD_TLS") commit aca52c39 ("mm: remove CONFIG_HAVE_MEMBLOCK") commit 3f08a302 ("mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option") remove the mentioned config symbol, and enable the intended setup by default without configuration. Drop these obsolete selects in loongarch's Kconfig. Reviewed-by:

Of particular note is a fix for a test flake that occurred on especially fast systems that boot in less than a second. 2) An addition during this cycle of some s390 crypto interacted with the way wireguard selects dependencies, resulting in linker errors reported by the kernel test robot. So Vladis sent in a patch for that, which also required a small preparatory fix moving some Kconfig symbols around. ==================== Link: https://lore.kernel.org/r/20220707003157.526645-1-Jason@zx2c4.com Signed-off-by:

Various accelerated software implementation Kconfig values for S390 were mistakenly placed into drivers/crypto/Kconfig, even though they're mainly just SIMD code and live in arch/s390/crypto/ like usual. This gives them the very unusual dependency on CRYPTO_HW, which leads to problems elsewhere. This patch fixes the issue by moving the Kconfig values for non-hardware drivers into the usual place in crypto/Kconfig. Acked-by:

Not all platforms have an RTC, and rather than trying to force one into each, it's much easier to just set a fixed time. This is necessary because WireGuard's latest handshakes parameter is returned in wallclock time, and if the system time isn't set, and the system is really fast, then this returns 0, which trips the test. Turning this on requires setting CONFIG_COMPAT_32BIT_TIME=y, as musl doesn't support settimeofday without it. Signed-off-by:

There are UAF bugs caused by rose_t0timer_expiry(). The root cause is that del_timer() could not stop the timer handler that is running and there is no synchronization. One of the race conditions is shown below: (thread 1) | (thread 2) | rose_device_event | rose_rt_device_down | rose_remove_neigh rose_t0timer_expiry | rose_stop_t0timer(rose_neigh) ... | del_timer(&neigh->t0timer) | kfree(rose_neigh) //[1]FREE neigh->dce_mode //[2]USE | The rose_neigh is deallocated in position [1] and use in position [2].

The in-kernel path manager code for changing subflow flags acquired both the msk socket lock and the PM lock when possibly changing the "backup" and "fullmesh" flags. mptcp_pm_nl_mp_prio_send_ack() does not access anything protected by the PM lock, and it must release and reacquire the PM lock. By pushing the PM lock to where it is needed in mptcp_pm_nl_fullmesh(), the lock is only acquired when the fullmesh flag is changed and the backup flag code no longer has to release and reacquire the PM lock. The change in locking context requires the MIB update to be modified - move that to a better location instead. This change also makes it possible to call mptcp_pm_nl_mp_prio_send_ack() for the userspace PM commands without manipulating the in-kernel PM lock.

`cancel_work_sync(&hdev->power_on)` was moved to hci_dev_close_sync in commit [1] to ensure that power_on work is canceled after HCI interface down. But, in certain cases power_on work function may call hci_dev_close_sync itself: hci_power_on -> hci_dev_do_close -> hci_dev_close_sync -> cancel_work_sync(&hdev->power_on), causing deadlock. In particular, this happens when device is rfkilled on boot. To avoid deadlock, move power_on work canceling out of hci_dev_do_close/hci_dev_close_sync. Deadlock introduced by commit [1] was reported in [2,3] as broken suspend. Suspend did not work because `hdev->req_lock` held as result of `power_on` work deadlock. In fact, other BT features were not working. It was not observed when testing [1] since it was verified without rfkill in place. NOTE: It is not needed to cancel power_on work from other places where hci_dev_do_close/hci_dev_close_sync is called in case: * Requests were serialized due to `hdev->req_workqueue`. The power_on work is first in that workqueue. * hci_rfkill_set_block which won't close device anyway until HCI_SETUP is on. * hci_sock_release which runs after hci_sock_bind which ensures HCI_SETUP was cleared. As result, behaviour is the same as in pre-dd06ed7 commit, except power_on work cancel added to hci_dev_close.

The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free().

Vladimir Oltean says: ==================== Fix bridge_vlan_aware.sh and bridge_vlan_unaware.sh with IFF_UNICAST_FLT Make sure that h1 and h2 don't drop packets with a random MAC DA, which otherwise confuses these selftests. Also, fix an incorrect error message found during those failures. ==================== Link: https://lore.kernel.org/r/20220703073626.937785-1-vladimir.oltean@nxp.com Signed-off-by:

When packets are not received, they aren't received on $host1_if, so the message talking about the second host not receiving them is incorrect. Fix it. Fixes: d4deb014 ("selftests: forwarding: Add a test for FDB learning") Signed-off-by:

The first host interface has by default no interest in receiving packets MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc filter and this might confuse the selftest. Enable promiscuous mode such that the filter properly counts received packets. Fixes: d4deb014 ("selftests: forwarding: Add a test for FDB learning") Signed-off-by:
