Subject: [PATCH] sctp: fix dst refcnt leak in sctp_v4_get_dst
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix dst reference count leak in sctp_v4_get_dst() introduced in commit
410f03831 ("sctp: add routing output fallback"):
When walking the address_list, successive ip_route_output_key() calls
may return the same rt->dst with the reference incremented on each call.
The code would not decrement the dst refcount when the dst pointer was
identical from the previous iteration, causing the dst refcnt leak.
Testcase:
ip netns add TEST
ip netns exec TEST ip link set lo up
ip link add dummy0 type dummy
ip link add dummy1 type dummy
ip link add dummy2 type dummy
ip link set dev dummy0 netns TEST
ip link set dev dummy1 netns TEST
ip link set dev dummy2 netns TEST
ip netns exec TEST ip addr add 192.168.1.1/24 dev dummy0
ip netns exec TEST ip link set dummy0 up
ip netns exec TEST ip addr add 192.168.1.2/24 dev dummy1
ip netns exec TEST ip link set dummy1 up
ip netns exec TEST ip addr add 192.168.1.3/24 dev dummy2
ip netns exec TEST ip link set dummy2 up
ip netns exec TEST sctp_test -H 192.168.1.2 -P 20002 -h 192.168.1.1 -p 20000 -s -B 192.168.1.3
ip netns del TEST
In 4.4 and 4.9 kernels this results to:
[ 354.179591] unregister_netdevice: waiting for lo to become free. Usage count = 1
[ 364.419674] unregister_netdevice: waiting for lo to become free. Usage count = 1

Subject: [PATCH] sctp: fix dst refcnt leak in sctp_v6_get_dst()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When going through the bind address list in sctp_v6_get_dst() and
the previously found address is better ('matchlen > bmatchlen'),
the code continues to the next iteration without releasing currently
held destination.
Fix it by releasing 'bdst' before continue to the next iteration, and
instead of introducing one more '!IS_ERR(bdst)' check for dst_release(),
move the already existed one right after ip6_dst_lookup_flow(), i.e. we
shouldn't proceed further if we get an error for the route lookup.
