Commit c182f90bc1f22ce5039b8722e45621d5f96862c2 ("SCTP: fix race between sctp_bind_addr_free() and sctp_bind_addr_conflict()") and commit 1231f0baa547a541a7481119323b7f964dda4788 ("net,rcu: convert call_rcu(sctp_local_addr_free) to kfree_rcu()"), happening in different trees, introduced a build failure. Simply make the SCTP race fix use kfree_rcu() too. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-05-19SCTP: fix race between sctp_bind_addr_free() and sctp_bind_addr_conflict()Jacek Luczak
During the sctp_close() call, we do not use rcu primitives to destroy the address list attached to the endpoint. At the same time, we do the removal of addresses from this list before attempting to remove the socket from the port hash As a result, it is possible for another process to find the socket in the port hash that is in the process of being closed. It then proceeds to traverse the address list to find the conflict, only to have that address list suddenly disappear without rcu() critical section. Fix issue by closing address list removal inside RCU critical section. Race can result in a kernel crash with general protection fault or kernel NULL pointer dereference: kernel: general protection fault: 0000 [#1] SMP kernel: RIP: 0010:[<ffffffffa02f3dde>] [<ffffffffa02f3dde>] sctp_bind_addr_conflict+0x64/0x82 [sctp] kernel: Call Trace: kernel: [<ffffffffa02f415f>] ? sctp_get_port_local+0x17b/0x2a3 [sctp] kernel: [<ffffffffa02f3d45>] ? sctp_bind_addr_match+0x33/0x68 [sctp] kernel: [<ffffffffa02f4416>] ? sctp_do_bind+0xd3/0x141 [sctp] kernel: [<ffffffffa02f5030>] ? sctp_bindx_add+0x4d/0x8e [sctp] kernel: [<ffffffffa02f5183>] ? sctp_setsockopt_bindx+0x112/0x4a4 [sctp] kernel: [<ffffffff81089e82>] ? generic_file_aio_write+0x7f/0x9b kernel: [<ffffffffa02f763e>] ? sctp_setsockopt+0x14f/0xfee [sctp] kernel: [<ffffffff810c11fb>] ? do_sync_write+0xab/0xeb kernel: [<ffffffff810e82ab>] ? fsnotify+0x239/0x282 kernel: [<ffffffff810c2462>] ? alloc_file+0x18/0xb1 kernel: [<ffffffff8134a0b1>] ? compat_sys_setsockopt+0x1a5/0x1d9 kernel: [<ffffffff8134aaf1>] ? compat_sys_socketcall+0x143/0x1a4 kernel: [<ffffffff810467dc>] ? sysenter_dispatch+0x7/0x32 Signed-off-by: Jacek Luczak <luczak.jacek@gmail.com> Acked-by: Vlad Yasevich <vladislav.yasevich@hp.com> CC: Eric Dumazet <eric.dumazet@gmail.com> Reviewed-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-04-19sctp: teach CACC algorithm about removed transportsVlad Yasevich
When we have have to remove a transport due to ASCONF, we move the data to a new active path. This can trigger CACC algorithm to not mark that data as missing when SACKs arrive. This is because the transport passed to the CACC algorithm is the one this data is sitting on, not the one it was sent on (that one may be gone). So, by sending the original transport (even if it's NULL), we may start marking data as missing.

2011-04-01sctp: malloc enough room for asconf-ack chunkWei Yongjun
Sometime the ASCONF_ACK parameters can equal to the fourfold of ASCONF parameters, this only happend in some special case: ASCONF parameter is : Unrecognized Parameter (4 bytes) ASCONF_ACK parameter should be: Error Cause Indication parameter (8 bytes header) + Error Cause (4 bytes header) + Unrecognized Parameter (4bytes) Four 4bytes Unrecognized Parameters in ASCONF chunk will cause panic.

2011-03-30sctp: Pass __GFP_NOWARN to hash table allocation attempts.David S. Miller
Like DCCP and other similar pieces of code, there are mechanisms here to try allocating smaller hash tables if the allocation fails. So pass in __GFP_NOWARN like the others do instead of emitting a scary message. Reported-by: Dave Jones <davej@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-12net: Make flowi ports AF dependent.David S. Miller
Create two sets of port member accessors, one set prefixed by fl4_* and the other prefixed by fl6_* This will let us to create AF optimal flow instances. It will work because every context in which we access the ports, we have to be fully aware of which AF the flowi is anyways. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Put flowi_* prefix on AF independent members of struct flowiDavid S. Miller
I intend to turn struct flowi into a union of AF specific flowi structs. There will be a common structure that each variant includes first, much like struct sock_common. This is the first step to move in that direction. Signed-off-by: David S. Miller <davem@davemloft.net>
