Previously, I failed to realize that Kees' patch [1] has not been merged into the mainline yet, and dropped DEBUG_INFO=y too eagerly from the mainline. As the results, "make debug.config" won't be able to flip DEBUG_INFO=n from the existing .config. This should close the gaps of a few weeks before Kees' patch is there, and work regardless of their merging status anyway.

In our testing, a livelock task was found. Through sysrq printing, same stack was found every time, as follows: __swap_duplicate+0x58/0x1a0 swapcache_prepare+0x24/0x30 __read_swap_cache_async+0xac/0x220 read_swap_cache_async+0x58/0xa0 swapin_readahead+0x24c/0x628 do_swap_page+0x374/0x8a0 __handle_mm_fault+0x598/0xd60 handle_mm_fault+0x114/0x200 do_page_fault+0x148/0x4d0 do_translation_fault+0xb0/0xd4 do_mem_abort+0x50/0xb0 The reason for the livelock is that swapcache_prepare() always returns EEXIST, indicating that SWAP_HAS_CACHE has not been cleared, so that it cannot jump out of the loop. We suspect that the task that clears the SWAP_HAS_CACHE flag never gets a chance to run. We try to lower the priority of the task stuck in a livelock so that the task that clears the SWAP_HAS_CACHE flag will run. The results show that the system returns to normal after the priority is lowered. In our testing, multiple real-time tasks are bound to the same core, and the task in the livelock is the highest priority task of the core, so the livelocked task cannot be preempted. Although cond_resched() is used by __read_swap_cache_async, it is an empty function in the preemptive system and cannot achieve the purpose of releasing the CPU. A high-priority task cannot release the CPU unless preempted by a higher-priority task. But when this task is already the highest priority task on this core, other tasks will not be able to be scheduled. So we think we should replace cond_resched() with schedule_timeout_uninterruptible(1), schedule_timeout_interruptible will call set_current_state first to set the task state, so the task will be removed from the running queue, so as to achieve the purpose of giving up the CPU and prevent it from running in kernel mode for too long. (akpm: ugly hack becomes uglier. But it fixes the issue in a backportable-to-stable fashion while we hopefully work on something better) Link: https://lkml.kernel.org/r/20220221111749.1928222-1-cgel.zte@gmail.comSigned-off-by:

Recent commit 97457801 ("iavf: Add waiting so the port is initialized in remove") adds a wait-loop at the beginning of iavf_remove() to ensure that port initialization is finished prior unregistering net device. This causes a regression in reboot/shutdown scenario because in this case callback iavf_shutdown() is called and this callback detaches the device, makes it down if it is running and sets its state to __IAVF_REMOVE. Later shutdown callback of associated PF driver (e.g. ice_shutdown) is called. That callback calls among other things sriov_disable() that calls indirectly iavf_remove() (see stack trace below). As the adapter state is already __IAVF_REMOVE then the mentioned loop is end-less and shutdown process hangs. The patch fixes this by checking adapter's state at the beginning of iavf_remove() and skips the rest of the function if the adapter is already in remove state (shutdown is in progress). Reproducer: 1. Create VF on PF driven by ice or i40e driver 2. Ensure that the VF is bound to iavf driver 3.

ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since the blamed commit, through a chain index whose number encodes a specific PAG (Policy Action Group) and lookup number. The chain number is translated through ocelot_chain_to_pag() into a PAG, and through ocelot_chain_to_lookup() into a lookup number. The problem with the blamed commit is that the above 2 functions don't have special treatment for chain 0. So ocelot_chain_to_pag(0) returns filter->pag = 224, which is in fact -32, but the "pag" field is an u8. So we end up programming the hardware with VCAP IS2 entries having a PAG of 224. But the way in which the PAG works is that it defines a subset of VCAP IS2 filters which should match on a packet. The default PAG is 0, and previous VCAP IS1 rules (which we offload using 'goto') can modify it. So basically, we are installing filters with a PAG on which no packet will ever match. This is the hardware equivalent of adding filters to a chain which has no 'goto' to it. Restore the previous functionality by making ACL filters offloaded to chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly correct, but the choice of lookup number isn't "as before" (which was to leave the lookup a "don't care"). However, lookup 0 should be fine, since even though there are ACL actions (policers) which have a requirement to be used in a specific lookup, that lookup is 0.

The RXCHK block will return a partial checksum of 0 if it encounters a problem while receiving a packet. Since a 1's complement sum can only produce this result if no bits are set in the received data stream it is fair to treat it as an invalid partial checksum and not pass it up the stack.

Direct firmware load for bnx2x/bnx2x-e2-7.13.15.0.fw failed with error -2 Direct firmware load for bnx2x/bnx2x-e2-7.13.21.0.fw failed with error -2 This patch fixes this issue by - 1. Removing request_firmware() logic from the probe() such that .ndo_open() handle it as it used to handle it earlier 2. Given request_firmware() is removed from probe(), so driver has to relax FW version comparisons a bit against the already loaded FW version (by some other PFs of same adapter) to allow different compatible/close enough FWs with which multiple PFs may run with (in different environments), as the given PF who is in probe flow has no idea now with which firmware file version it is going to initialize the device in ndo_open() Link: https://lore.kernel.org/all/46f2d9d9-ae7f-b332-ddeb-b59802be2bab@molgen.mpg.de/Reported-by:

What prevents this code from being a forever loop is that later there is a separate check for if (queue == 0). The "queue" variable is less than MTL_MAX_RX_QUEUES (8) so it can easily fit in an int type. Any larger value for "queue" would lead to an array overflow when we assign "rx_q = &priv->rx_queue[queue]".

In file hamradio/baycom_epp.c, the baycom_setmode interface, there is a problem with improper use of strstr. Suppose that when modestr="noloopback", both conditions which are 'strstr(modestr,"noloopback")' and 'strstr(modestr,"loopback")' will be true(not NULL), this lead the bc->cfg.loopback variable will be first assigned to 0, and then reassigned to 1. This will cause 'bc->cfg.loopback = 0' will never take effect. That obviously violates the logic of the code, so adjust the order of their execution to solve the problem. Signed-off-by:

bareudp_create_sock() use AF_INET6 by default if IPv6 CONFIG enabled. But if user start kernel with ipv6.disable=1, the bareudp sock will created failed, which cause the interface open failed even with ethertype ip. e.g. # ip link add bareudp1 type bareudp dstport 2 ethertype ip # ip link set bareudp1 up RTNETLINK answers: Address family not supported by protocol Fix it by using ipv6_mod_enabled() to check if IPv6 enabled. There is no need to check IS_ENABLED(CONFIG_IPV6) as ipv6_mod_enabled() will return false when CONFIG_IPV6 no enabled in include/linux/ipv6.h. Reported-by:

Amit Kumar Mahapatra converts the xilinx,can device tree bindings to yaml. The last patch is by Julia Lawall and fixes typos in the ucan driver. * tag 'linux-can-next-for-5.18-20220316' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: can: ucan: fix typos in comments dt-bindings: can: xilinx_can: Convert Xilinx CAN binding to YAML can: isotp: support MSG_TRUNC flag when reading from socket can: isotp: return -EADDRNOTAVAIL when reading from unbound socket can: isotp: sanitize CAN ID checks in isotp_bind() ==================== Link: https://lore.kernel.org/r/20220316204710.716341-1-mkl@pengutronix.deSigned-off-by:

When providing the MSG_TRUNC flag via recvmsg() syscall the return value provides the real length of the packet or datagram, even when it was longer than the passed buffer.

When reading from an unbound can-isotp socket the syscall blocked indefinitely. As unbound sockets (without given CAN address information) do not make sense anyway we directly return -EADDRNOTAVAIL on read() analogue to the known behavior from sendmsg().
