igmp: convert struct ip_sf_list to RCU

2026-09-01T00:22:03+00:00

Commit 23d2b94043ca ("igmp: Add ip_mc_list lock in ip_check_mc_rcu") added spin_lock_bh(&im->lock) to ip_check_mc_rcu() to prevent a use-after-free while iterating im->sources during concurrent deletions. However, ip_check_mc_rcu() is called from RCU read-side critical sections in packet receive and route lookup fast paths (e.g. __mkroute_output(), ip_route_input_rcu(), and __udp4_lib_rcv()). When igmpv3_send_cr() or igmpv3_send_report() holds &pmc->lock and calls add_grec() -> igmpv3_newpack() -> ip_route_output_ports(), an XFRM policy matching a multicast destination triggers xfrm_tmpl_resolve_one() -> xfrm4_get_saddr() -> __mkroute_output() -> ip_check_mc_rcu(). This attempts to acquire &im->lock while &pmc->lock is already held on the same CPU, triggering a lockdep recursive locking warning / deadlock. Fix this by converting IPv4 struct ip_sf_list to RCU, mirroring the IPv6 implementation in net/ipv6/mcast.c: 1. Add struct rcu_head to struct ip_sf_list and annotate sf_next, sources, and tomb as __rcu pointers. 2. Use rcu_assign_pointer() and kfree_rcu() for list updates and deletions. 3. Remove spin_lock_bh(&im->lock) from ip_check_mc_rcu() and traverse im->sources locklessly with for_each_psf_rcu(), reading and writing counter fields with READ_ONCE() and WRITE_ONCE(). Note: RCU conversion of /proc/net/mcfilter will be done in a separate patch.

cgroup: fix spurious SIGKILL of CLONE_INTO_CGROUP children

2026-08-31T16:19:38+00:00

Since commit b69bb476dee9 ("cgroup: fix race between fork and cgroup.kill"), the fork path snapshots the kill_seq of the child's future cgroup into kargs->kill_seq, and cgroup_post_fork() SIGKILLs the child if that cgroup's kill_seq has changed in the meantime, to catch forks racing with a cgroup.kill sweep. For CLONE_INTO_CGROUP, however, the snapshot in cgroup_css_set_fork() is taken before the target cgroup has been resolved: kargs->cgrp is always NULL at this point (it is only set at the end of the function). So the "if (kargs->cgrp)" branch is dead code and the snapshot always records the kill_seq of the parent's cgroup. cgroup_post_fork() then compares it with the kill_seq of the target cgroup, so the child gets SIGKILLed whenever the two cgroups have been killed a different number of times. As a result, once cgroup.kill has been written to a cgroup, every child subsequently cloned into it with clone3(CLONE_INTO_CGROUP) is killed on the spot, for as long as the cgroup exists: kill_seq is not exposed to userspace and never resets. Re-snapshot kill_seq from the target cgroup once it has been resolved, and drop the dead branch at the early snapshot site. This does not reopen the race fixed by b69bb476dee9. For CLONE_INTO_CGROUP, everything from the snapshot to the check in cgroup_post_fork() runs with cgroup_mutex held, and kill_seq is only ever incremented under cgroup_mutex. tj: Updated the comment above kill_seq to reflect the new serialization rules as suggested by Shakeel Butt.
