Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - net：bridge：mcast：修复主 VLAN 的多播上下文的释放后使用 br_multicast_toggle_one_vlan（） 在停止 VLAN 的多播上下文之前清除 br->multicast_lock 下的BR_VLFLAG_MCAST_ENABLED。这就是拆卸握手：无锁的阅读器通过 br_multicast_ctx_should_use（） -> br_multicast_ctx_vlan_disabled（） 在标记上进行门控，因此一旦它在锁定下被清除，任何阅读器都不能再次布防上下文。对于主 VLAN，从不运行握手。__vlan_del（） 会在调用 br_vlan_put_master（） 之前清除BRIDGE_VLAN_INFO_BRENTRY，因此 br_multicast_toggle_one_vlan（masterv， false） 会提早返回 ！br_vlan_is_brentry（vlan）：此标记维持设置状态，且从不采用 br->multicast_lock。然后，br_vlan_put_master（） 耗尽 br_multicast_ctx_deinit（） 中的上下文并通过 call_rcu（） 释放 VLAN，而仍在 rcu_read_lock（） 内的阅读器将上下文视为启用并重新布防它。函数的 port 和 port-VLAN 分支没有 br_vlan_is_brentry（） 测试，并且会在 br->multicast_lock 下翻转标记，因此不受影响。读卡器是桥接传输路径。对于主 VLAN br_multicast_rcv（） 选择 brmctx = &vlan->br_mcast_ctx 且 pmctx = NULL，因此在 br_multicast_ctx_deinit（） 停止上下文定时器之后，发送到桥接设备的 IGMP 会重新布防这些定时器。缺陷：KASAN：在 detach_if_pending+0x412/0x4a0 中通过任务 brmc/601 在地址 ffff88810ac39918 处写入大小为 8 的 slab-after-free

  - 已修复 Linux 内核中的下列漏洞：net/sched: act_mirred: use the backlog for mirred ingress The test Davide added in commit ca22da2fbd69 (act_mirred: use the backlog for nested calls to mirred ingress) hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress -> ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround does not seem to address the issue.

  - 已修复 Linux 内核中的下列漏洞：vfs: Don't evict inode under the inode lru traversing context The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen. Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this: 1. File A has inode i_reg and an ea inode i_ea 2. getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea 3. Then, following three processes running like this: PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast
    __wait_on_freeing_inode(i_ea) ---- AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state) Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following: 1. File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr. 2. getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa 3. Then, following three processes running like this: PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0 rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast
