* mld: change lockdep annotation for ip6_sf_socklist and ipv6_mc_socklistTaehee Yoo2021-04-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct ip6_sf_socklist and ipv6_mc_socklist are per-socket MLD data. These data are protected by rtnl lock, socket lock, and RCU. So, when these are used, it verifies whether rtnl lock is acquired or not. ip6_mc_msfget() is called by do_ipv6_getsockopt(). But caller doesn't acquire rtnl lock. So, when these data are used in the ip6_mc_msfget() lockdep warns about it. But accessing these is actually safe because socket lock was acquired by do_ipv6_getsockopt(). So, it changes lockdep annotation from rtnl lock to socket lock. (rtnl_dereference -> sock_dereference) Locking graph for mld data is like below: When writing mld data: do_ipv6_setsockopt() rtnl_lock lock_sock (mld functions) idev->mc_lock(if per-interface mld data is modified) When reading mld data: do_ipv6_getsockopt() lock_sock ip6_mc_msfget() Splat looks like: ============================= WARNING: suspicious RCU usage 5.12.0-rc4+ #503 Not tainted ----------------------------- net/ipv6/mcast.c:610 suspicious rcu_dereference_protected() usage! other info that might help us debug this: rcu_scheduler_active = 2, debug_locks = 1 1 lock held by mcast-listener-/923: #0: ffff888007958a70 (sk_lock-AF_INET6){+.+.}-{0:0}, at: ipv6_get_msfilter+0xaf/0x190 stack backtrace: CPU: 1 PID: 923 Comm: mcast-listener- Not tainted 5.12.0-rc4+ #503 Call Trace: dump_stack+0xa4/0xe5 ip6_mc_msfget+0x553/0x6c0 ? ipv6_sock_mc_join_ssm+0x10/0x10 ? lockdep_hardirqs_on_prepare+0x3e0/0x3e0 ? mark_held_locks+0xb7/0x120 ? lockdep_hardirqs_on_prepare+0x27c/0x3e0 ? __local_bh_enable_ip+0xa5/0xf0 ? lock_sock_nested+0x82/0xf0 ipv6_get_msfilter+0xc3/0x190 ? compat_ipv6_get_msfilter+0x300/0x300 ? lock_downgrade+0x690/0x690 do_ipv6_getsockopt.isra.6.constprop.13+0x1809/0x29e0 ? do_ipv6_mcast_group_source+0x150/0x150 ? register_lock_class+0x1750/0x1750 ? kvm_sched_clock_read+0x14/0x30 ? sched_clock+0x5/0x10 ? sched_clock_cpu+0x18/0x170 ? find_held_lock+0x3a/0x1c0 ? lock_downgrade+0x690/0x690 ? ipv6_getsockopt+0xdb/0x1b0 ipv6_getsockopt+0xdb/0x1b0 [ ... ] Fixes: 88e2ca308094 ("mld: convert ifmcaddr6 to RCU") Reported-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S.

* tipc: fix unique bearer names sanity checkHoang Le2021-04-011-19/+27
| | | | | | | | | | | | | | | When enabling a bearer by name, we don't sanity check its name with higher slot in bearer list. This may have the effect that the name of an already enabled bearer bypasses the check. To fix the above issue, we just perform an extra checking with all existing bearers.

* | tipc: move creation of publication item one level up in call chainJon Maloy2021-03-171-33/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We instantiate struct publication in tipc_nametbl_insert_publ() instead of as currently in tipc_service_insert_publ(). This has the advantage that we can pass a pointer to the publication struct to the next call levels, instead of the numerous individual parameters we pass on now. It also gives us a location to keep the contents of the additional fields we will introduce in a later commit.

* | tipc: re-organize members of struct publicationJon Maloy2021-03-174-97/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a future commit we will introduce more members to struct publication. In order to keep this structure comprehensible we now group some of its current fields into the sub-structures where they really belong, - A struct tipc_service_range for the functional address the publication is representing. - A struct tipc_socket_addr for the socket bound to that service range. We also rename the stack variable 'publ' to just 'p' in a few places. This is just as easy to understand in the given context, and keeps the number of wrapped code lines to a minimum. There are no functional changes in this commit.

However, we did not apply this new MTU value at node level. This lead to packet dropped at link level if its size is greater than new MTU value. To fix this issue, we also apply this new MTU value for node level.
