This change was made\nby commit ce8ea7cc6eb313 (\"btrfs: don\u0027t call btrfs_start_delalloc_roots\nin flushoncommit\"). After that change we started producing that warning,\nand every now and then a user reports this since the warning happens too\noften, it spams dmesg/syslog, and a user is unsure if this reflects any\nproblem that might compromise the filesystem\u0027s reliability.\n\nWe can not just lock the sb-\u003es_umount semaphore before calling\nwriteback_inodes_sb(), because that would at least deadlock with\nfilesystem freezing, since at fs/super.c:freeze_super() sync_filesystem()\nis called while we are holding that semaphore in write mode, and that can\ntrigger a transaction commit, resulting in a deadlock. It would also\ntrigger the same type of deadlock in the unmount path. Possibly, it could\nalso introduce some other locking dependencies that lockdep would report.\n\nTo fix this call try_to_writeback_inodes_sb() instead of\nwriteback_inodes_sb(), because that will try to read lock sb-\u003es_umount\nand then will only call writeback_inodes_sb() if it was able to lock it.\nThis is fine because the cases where it can\u0027t read lock sb-\u003es_umount\nare during a filesystem unmount or during a filesystem freeze - in those\ncases sb-\u003es_umount is write locked and sync_filesystem() is called, which\ncalls writeback_inodes_sb(). In other words, in all cases where we can\u0027t\ntake a read lock on sb-\u003es_umount, writeback is already being triggered\nelsewhere.\n\nAn alternative would be to call btrfs_start_delalloc_roots() with a\nnumber of pages different from LONG_MAX, for example matching the number\nof delalloc bytes we currently have, in \n---truncated---"

This results in the VF potentially removing\nits DMA memory before the PF has shut down the device queues.\n\nAdditionally, the fix doesn\u0027t actually resolve concurrency issues within\nthe ice driver. It is possible for a VF to initiate a reset just prior\nto the ice driver removing VFs. This can result in the remove task\nconcurrently operating while the VF is being reset. This results in\nsimilar memory corruption and panics purportedly fixed by that commit.\n\nFix this concurrency at its root by protecting both the reset and\nremoval flows using the existing VF cfg_lock. This ensures that we\ncannot remove the VF while any outstanding critical tasks such as a\nvirtchnl message or a reset are occurring.\n\nThis locking change also fixes the root cause originally fixed by commit\nc503e63200c6 (\"ice: Stop processing VF messages during teardown\"), so we\ncan simply revert it.\n\nNote that I kept these two changes together because simply reverting the\noriginal commit alone would leave the driver vulnerable to worse race\nconditions."

This has been bisected to\ncommit 4ef0c5c6b5ba (\"kernel/sched: Fix sched_fork() access an invalid\nsched_task_group\")\n\nThere\u00a0is a race between sched_post_fork() and setpriority(PRIO_PGRP)\nwithin a thread group that causes a null-ptr-deref\u00a0in\nreweight_entity() in CFS. The scenario is that the main process spawns\nnumber of new threads, which then call setpriority(PRIO_PGRP, 0, -20),\nwait, and exit.  For each of the new threads the copy_process() gets\ninvoked, which adds the new task_struct and calls sched_post_fork()\nfor it.\n\nIn the above scenario there is a possibility that\nsetpriority(PRIO_PGRP) and set_one_prio() will be called for a thread\nin the group that is just being created by copy_process(), and for\nwhich the sched_post_fork() has not been executed yet. This will\ntrigger a null pointer dereference in reweight_entity(),\u00a0as it will\ntry to access the run queue pointer, which hasn\u0027t been set.\n\nBefore the mentioned change the cfs_rq pointer for the task  has been\nset in sched_fork(), which is called much earlier in copy_process(),\nbefore the new task is added to the thread_group.  Now it is done in\nthe sched_post_fork(), which is called after that.  To fix the issue\nthe remove the update_load param from the update_load param() function\nand call reweight_task() only if the task flag doesn\u0027t have the\nTASK_NEW flag set."

If they do then we know we were in the\nmiddle of the drop operation and set a flag on the fs_info.  Then\nbalance can wait until this flag is cleared to start up again.\n\nIf there are DEAD_ROOT\u0027s that don\u0027t have a drop_progress set then we\u0027re\nsafe to start balance right away as we\u0027ll be properly protected by the\ncleaner_mutex."

This will cause a\nnew entry in idev-\u003emc_tomb to be allocated for each multicast group\nthe interface is subscribed to, which in turn leaks one struct ifmcaddr6\nper nontrivial multicast group the interface is subscribed to.\n\nThe following reproducer will leak at least $n objects:\n\nip addr add ff2e::4242/32 dev eth0 autojoin\nsysctl -w net.ipv6.conf.eth0.disable_ipv6=1\nfor i in $(seq 1 $n); do\n\tip link set up eth0; ip link set down eth0\ndone\n\nJoining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting the\nsysctl net.ipv6.conf.eth0.forwarding to 1 (=\u003e subscribing to ff02::2)\ncan also be used to create a nontrivial idev-\u003emc_list, which will the\nleak objects with the right up-down-sequence.\n\nBased on both sources for NETDEV_DOWN events the interface IPv6 state\nshould be considered:\n\n - not ready if the network interface is not ready OR IPv6 is disabled\n   for it\n - ready if the network interface is ready AND IPv6 is enabled for it\n\nThe functions ipv6_mc_up() and ipv6_down() should only be run when this\nstate changes.\n\nImplement this by remembering when the IPv6 state is ready, and only\nrun ipv6_mc_down() if it actually changed from ready to not ready.\n\nThe other direction (not ready -\u003e ready) already works correctly, as:\n\n - the interface notification triggered codepath for NETDEV_UP /\n   NETDEV_CHANGE returns early if ipv6 is disabled, and\n - the disable_ipv6=0 triggered codepath skips fully initializing the\n   interface as long as addrconf_link_ready(dev) returns false\n - calling ipv6_mc_up() repeatedly does not leak anything"

It didn\u0027t keep\nus from continuing to use a buffer that we already had found.\n\nIn this case we\u0027re searching the commit root to cache the block group,\nso we can start committing the transaction and switch the commit root\nand then start writing.  After the switch we can look up an extent\nbuffer that hasn\u0027t been written yet and start processing that block\ngroup.  Then we fail to write that block out and clear Uptodate on the\npage, and then we start spewing these errors.\n\nNormally we\u0027re protected by the tree lock to a certain degree here.  If\nwe read a block we have that block read locked, and we block the writer\nfrom locking the block before we submit it for the write.  However this\nisn\u0027t necessarily fool proof because the read could happen before we do\nthe submit_bio and after we locked and unlocked the extent buffer.\n\nAlso in this particular case we have path-\u003eskip_locking set, so that\nwon\u0027t save us here.  We\u0027ll simply get a block that was valid when we\nread it, but became invalid while we were using it.\n\nWhat we really want is to catch the case where we\u0027ve \"read\" a block but\nit\u0027s not marked Uptodate.  On read we ClearPageError(), so if we\u0027re\n!Uptodate and !Error we know we didn\u0027t do the right thing for reading\nthe page.\n\nFix this by checking !Uptodate \u0026\u0026 !Error, this way we will not complain\nif our buffer gets invalidated while we\u0027re using it, and we\u0027ll maintain\nthe spirit of the check which is to make sure we have a fully in-cache\nblock while we\u0027re messing with it."

Therefore, it is impossible for the to be\ndisconnected at all.\n\nThis patch tries a very simple way to avoid this issue, once the state\nhas changed to SMC_ACTIVE after tcp_abort(), we can actively abort the\nsmc connection, considering that the state is SMC_INIT before\ntcp_abort(), abandoning the complete disconnection process should not\ncause too much problem.\n\nIn fact, this problem may exist as long as the CLC CONFIRM message is\nnot received by the server. Whether a timer should be added after\nsmc_close_final() needs to be discussed in the future. But even so, this\npatch provides a faster release for connection in above case, it should\nalso be valuable."

However, the current code does not set both s_off and\nt_off in copy_map_value, which leads to a crash when e.g. bpf_spin_lock\nis placed in map value with bpf_timer, as bpf_map_update_elem call will\nbe able to overwrite the other timer object.\n\nWhen the issue is not fixed, an overwriting can produce the following\nsplat:\n\n[root@(none) bpf]# ./test_progs -t timer_crash\n[   15.930339] bpf_testmod: loading out-of-tree module taints kernel.\n[   16.037849] ==================================================================\n[   16.038458] BUG: KASAN: user-memory-access in __pv_queued_spin_lock_slowpath+0x32b/0x520\n[   16.038944] Write of size 8 at addr 0000000000043ec0 by task test_progs/325\n[   16.039399]\n[   16.039514] CPU: 0 PID: 325 Comm: test_progs Tainted: G           OE     5.16.0+ #278\n[   16.039983] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS ArchLinux 1.15.0-1 04/01/2014\n[   16.040485] Call Trace:\n[   16.040645]  \u003cTASK\u003e\n[   16.040805]  dump_stack_lvl+0x59/0x73\n[   16.041069]  ? __pv_queued_spin_lock_slowpath+0x32b/0x520\n[   16.041427]  kasan_report.cold+0x116/0x11b\n[   16.041673]  ? __pv_queued_spin_lock_slowpath+0x32b/0x520\n[   16.042040]  __pv_queued_spin_lock_slowpath+0x32b/0x520\n[   16.042328]  ? memcpy+0x39/0x60\n[   16.042552]  ? pv_hash+0xd0/0xd0\n[   16.042785]  ? lockdep_hardirqs_off+0x95/0xd0\n[   16.043079]  __bpf_spin_lock_irqsave+0xdf/0xf0\n[   16.043366]  ? bpf_get_current_comm+0x50/0x50\n[   16.043608]  ? jhash+0x11a/0x270\n[   16.043848]  bpf_timer_cancel+0x34/0xe0\n[   16.044119]  bpf_prog_c4ea1c0f7449940d_sys_enter+0x7c/0x81\n[   16.044500]  bpf_trampoline_6442477838_0+0x36/0x1000\n[   16.044836]  __x64_sys_nanosleep+0x5/0x140\n[   16.045119]  do_syscall_64+0x59/0x80\n[   16.045377]  ? lock_is_held_type+0xe4/0x140\n[   16.045670]  ? irqentry_exit_to_user_mode+0xa/0x40\n[   16.046001]  ? mark_held_locks+0x24/0x90\n[   16.046287]  ? asm_exc_page_fault+0x1e/0x30\n[   16.046569]  ? asm_exc_page_fault+0x8/0x30\n[   16.046851]  ? lockdep_hardirqs_on+0x7e/0x100\n[   16.047137]  entry_SYSCALL_64_after_hwframe+0x44/0xae\n[   16.047405] RIP: 0033:0x7f9e4831718d\n[   16.047602] Code: b4 0c 00 0f 05 eb a9 66 0f 1f 44 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 8b 0d b3 6c 0c 00 f7 d8 64 89 01 48\n[   16.048764] RSP: 002b:00007fff488086b8 EFLAGS: 00000206 ORIG_RAX: 0000000000000023\n[   16.049275] RAX: ffffffffffffffda RBX: 00007f9e48683740 RCX: 00007f9e4831718d\n[   16.049747] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 00007fff488086d0\n[   16.050225] RBP: 00007fff488086f0 R08: 00007fff488085d7 R09: 00007f9e4cb594a0\n[   16.050648] R10: 0000000000000000 R11: 0000000000000206 R12: 00007f9e484cde30\n[   16.051124] R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000\n[   16.051608]  \u003c/TASK\u003e\n[   16.051762] =================================================================="
