2022-06-17io_uring: recycle provided buffer if we punt to io-wqJens Axboe1-0/+1
io_arm_poll_handler() will recycle the buffer appropriately if we end up arming poll (or if we're ready to retry), but not for the io-wq case if we have attempted poll first. Explicitly recycle the buffer to avoid both hanging on to it too long, but also to avoid multiple reads grabbing the same one. This can happen for ring mapped buffers, since it hasn't necessarily been committed.

2022-06-16dm mirror log: round up region bitmap size to BITS_PER_LONGMikulas Patocka1-2/+1
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 Patocka1-1/+6
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 Patocka1-6/+7
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.

2022-06-16io_uring: commit non-pollable provided mapped buffers upfrontJens Axboe1-1/+1
For recv/recvmsg, IO either completes immediately or gets queued for a retry. This isn't the case for read/readv, if eg a normal file or a block device is used. Here, an operation can get queued with the block layer. If this happens, ring mapped buffers must get committed immediately to avoid that the next read can consume the same buffer. Check if we're dealing with pollable file, when getting a new ring mapped provided buffer. If it's not, commit it immediately rather than wait post issue. If we don't wait, we can race with completions coming in, or just plain buffer reuse by committing after a retry where others could have grabbed the same buffer.

bio_alloc_bioset() takes a block device, number of vectors, the OP flags, the GFP mask and the bio set. However when the prototype was changed, the callisite in ppl_do_flush() had the OP flags and the GFP flags reversed.

The 07reshape5intr test is broke because of below path. md_reap_sync_thread -> mddev_unlock -> md_unregister_thread(&mddev->sync_thread) And md_check_recovery is triggered by, mddev_unlock -> md_wakeup_thread(mddev->thread) then mddev->reshape_position is set to MaxSector in raid5_finish_reshape since MD_RECOVERY_INTR is cleared in md_check_recovery, which means feature_map is not set with MD_FEATURE_RESHAPE_ACTIVE and superblock's reshape_position can't be updated accordingly.

The skb_recv_datagram() in ax25_recvmsg() will hold lock_sock and block until it receives a packet from the remote. If the client doesn`t connect to server and calls read() directly, it will not receive any packets forever. As a result, the deadlock will happen.

2022-06-15net: usb: ax88179_178a needs FLAG_SEND_ZLPJose Alonso1-13/+13
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.

Whereas max_fall defines frame-average level luminance. The user may not observe the difference in brightness in between max_fall and max_cll. That negatively impacts the user experience.

2022-06-14ice: Fix queue config fail handlingPrzemyslaw Patynowski1-27/+26
Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail. Not disabling them might lead to scenario, where PF driver leaves VF queues enabled, when VF's VSI failed queue config. In this scenario VF should not have RX/TX queues enabled. If PF failed to set up VF's queues, VF will reset due to TX timeouts in VF driver. Initialize iterator 'i' to -1, so if error happens prior to configuring queues then error path code will not disable queue 0. Loop that configures queues will is using same iterator, so error path code will only disable queues that were configured.

VLAN filtering features, that is C-Tag and S-Tag, in DVM mode must be both enabled or disabled. In case of turning off/on only one of the features, another feature must be turned off/on automatically with issuing an appropriate message to the kernel log.

2022-06-14ice: Fix PTP TX timestamp offset calculationMichal Michalik2-1/+32
The offset was being incorrectly calculated for E822 - that led to collisions in choosing TX timestamp register location when more than one port was trying to use timestamping mechanism. In E822 one quad is being logically split between ports, so quad 0 is having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should have separate memory location for tracking timestamps. Due to error for example ports 1 and 2 had been assigned to quad 0 with same offset (0), while port 1 should have offset 0 and 1 offset 16. Fix it by correctly calculating quad offset.
