Steffen Klassert says: ==================== pull request (net): ipsec 2021-08-04 1) Fix a sysbot reported memory leak in xfrm_user_rcv_msg. From Pavel Skripkin. 2) Revert "xfrm: policy: Read seqcount outside of rcu-read side in xfrm_policy_lookup_bytype". This commit tried to fix a lockin bug, but only cured some of the symptoms. A proper fix is applied on top of this revert. 3) Fix a locking bug on xfrm state hash resize. A recent change on sequence counters accidentally repaced a spinlock by a mutex. Fix from Frederic Weisbecker. 4) Fix possible user-memory-access in xfrm_user_rcv_msg_compat(). From Dmitry Safonov. 5) Add initialiation sefltest fot xfrm_spdattr_type_t. From Dmitry Safonov. ==================== Signed-off-by: David S. Miller

selftests: net: add ESP-in-UDP PMTU test

The case of ESP in UDP encapsulation was not covered before. Add cases of local changes of MTU and difference on routed path. Signed-off-by: Vadim Fedorenko Signed-off-by: David S. Miller

selftests/net/ipsec: Add test for xfrm_spdattr_type_t

2021-07-21T07:53:25Z

Set hthresh, dump it again and verify thresh.lbits && thresh.rbits. They are passed as attributes of xfrm_spdattr_type_t, different from other message attributes that use xfrm_attr_type_t. Also, test attribute that is bigger than XFRMA_SPD_MAX, currently it should be silently ignored.

selftests: mptcp: fix case multiple subflows limited by server

2021-07-10T01:38:53Z

After patch "mptcp: fix syncookie process if mptcp can not_accept new subflow", if subflow is limited, MP_JOIN SYN is dropped, and no SYN/ACK will be replied. So in case "multiple subflows limited by server", the expected SYN/ACK number should be 1.

selftests: icmp_redirect: IPv6 PMTU info should be cleared after redirect

2021-07-07T20:45:30Z

After redirecting, it's already a new path. So the old PMTU info should be cleared. The IPv6 test "mtu exception plus redirect" should only has redirect info without old PMTU. The IPv4 test can not be changed because of legacy. Fixes: ec8105352869 ("selftests: Add redirect tests") Signed-off-by: Hangbin Liu Reviewed-by: David Ahern Signed-off-by: David S. Miller

selftests: icmp_redirect: remove from checking for IPv6 route get

2021-07-07T20:45:30Z

If the kernel doesn't enable option CONFIG_IPV6_SUBTREES, the RTA_SRC info will not be exported to userspace in rt6_fill_node(). And ip cmd will not print "from ::" to the route output. So remove this check. Fixes: ec8105352869 ("selftests: Add redirect tests") Signed-off-by: Hangbin Liu Reviewed-by: David Ahern Signed-off-by: David S. Miller
