2013-06-13sctp: fully initialize sctp_outq in sctp_outq_initNeil Horman1-4/+2
In commit 2f94aabd9f6c925d77aecb3ff020f1cc12ed8f86 (refactor sctp_outq_teardown to insure proper re-initalization) we modified sctp_outq_teardown to use sctp_outq_init to fully re-initalize the outq structure. Steve West recently asked me why I removed the q->error = 0 initalization from sctp_outq_teardown. I did so because I was operating under the impression that sctp_outq_init would properly initalize that value for us, but it doesn't. sctp_outq_init operates under the assumption that the outq struct is all 0's (as it is when called from sctp_association_init), but using it in __sctp_outq_teardown violates that assumption. We should do a memset in sctp_outq_init to ensure that the entire structure is in a known state there instead.

Then, again, allocating, binding, etc, and then killing child processes. This panic then only occurs when ``echo 1 > /proc/sys/net/sctp/auth_enable'' is set. The cause for that is actually very simple: in sctp_endpoint_init() we enter the path of sctp_auth_init_hmacs(). There, we try to allocate our crypto transforms through crypto_alloc_hash(). In our scenario, it then can happen that crypto_alloc_hash() fails with -EINTR from crypto_larval_wait(), thus we bail out and release the socket via sk_common_release(), sctp_destroy_sock() and hit the NULL pointer dereference as soon as we try to access members in the endpoint during sctp_endpoint_free(), since endpoint at that time is still NULL. Now, if we have that case, we do not need to do any cleanup work and just leave the destruction handler.

2013-04-16sctp: Add buffer utilization fields to /proc/net/sctp/assocsDilip Daya1-3/+9
sctp: Add buffer utilization fields to /proc/net/sctp/assocs This patch adds the following fields to /proc/net/sctp/assocs output: - sk->sk_wmem_alloc as "wmema" (transmit queue bytes committed) - sk->sk_wmem_queued as "wmemq" (persistent queue size) - sk->sk_sndbuf as "sndbuf" (size of send buffer in bytes) - sk->sk_rcvbuf as "rcvbuf" (size of receive buffer in bytes) When small DATA chunks containing 136 bytes data are sent the TX_QUEUE (assoc->sndbuf_used) reaches a maximum of 40.9% of sk_sndbuf value when peer.rwnd = 0. This was diagnosed from sk_wmem_alloc value reaching maximum value of sk_sndbuf. TX_QUEUE (assoc->sndbuf_used), sk_wmem_alloc and sk_wmem_queued values are incremented in sctp_set_owner_w() for outgoing data chunks. Having access to the above values in /proc/net/sctp/assocs will provide a better understanding of SCTP buffer management.

2013-03-31net: add option to enable error queue packets waking selectKeller, Jacob E1-1/+2
Currently, when a socket receives something on the error queue it only wakes up the socket on select if it is in the "read" list, that is the socket has something to read. It is useful also to wake the socket if it is in the error list, which would enable software to wait on error queue packets without waking up for regular data on the socket. The main use case is for receiving timestamped transmit packets which return the timestamp to the socket via the error queue. This enables an application to select on the socket for the error queue only instead of for the regular traffic. -v2- * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file * Modified every socket poll function that checks error queue Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Cc: Jeffrey Kirsher <jeffrey.t.kirsher@intel.com> Cc: Richard Cochran <richardcochran@gmail.com> Cc: Matthew Vick <matthew.vick@intel.com> Signed-off-by: David S.

2013-03-13sctp: Use correct sideffect command in duplicate cookie handlingVlad Yasevich1-1/+1
When SCTP is done processing a duplicate cookie chunk, it tries to delete a newly created association. For that, it has to set the right association for the side-effect processing to work. However, when it uses the SCTP_CMD_NEW_ASOC command, that performs more work then really needed (like hashing the associationa and assigning it an id) and there is no point to do that only to delete the association as a next step. In fact, it also creates an impossible condition where an association may be found by the getsockopt() call, and that association is empty. This causes a crash in some sctp getsockopts. The solution is rather simple. We simply use SCTP_CMD_SET_ASOC command that doesn't have all the overhead and does exactly what we need.

In sctp_ulpq_tail_data(), use return values 0,1 to indicate whether a complete event (with MSG_EOR set) was delivered. A return value of -ENOMEM continues to indicate an out-of-memory condition was encountered. In sctp_ulpq_retrieve_partial() and sctp_ulpq_retrieve_first(), correct message reassembly logic for SCTP partial delivery. Change logic to ensure that as much data as possible is sent with the initial partial delivery and that following partial deliveries contain all available data. In sctp_ulpq_partial_delivery(), attempt partial delivery only if the data on the head of the reassembly queue is at or before the cumulative TSN ACK point. In sctp_ulpq_renege(), use the modified return values from sctp_ulpq_tail_data() to choose whether to attempt partial delivery or to attempt to drain the reassembly queue as a means to reduce memory pressure. Remove call to sctp_tsnmap_mark(), as this is handled correctly in call to sctp_ulpq_tail_data(). Signed-off-by: Lee A.

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin4-17/+10
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2013-02-13net: sctp: sctp_v6_get_dst: fix boolean test in dst cacheDaniel Borkmann1-2/+3
We walk through the bind address list and try to get the best source address for a given destination. However, currently, we take the 'continue' path of the loop when an entry is invalid (!laddr->valid) *and* the entry state does not equal SCTP_ADDR_SRC (laddr->state != SCTP_ADDR_SRC). Thus, still, invalid entries with SCTP_ADDR_SRC might not 'continue' as well as valid entries with SCTP_ADDR_{NEW, SRC, DEL}, with a possible false baddr and matchlen as a result, causing in worst case dst route to be false or possibly NULL. This test should actually be a '||' instead of '&&'. But lets fix it and make this a bit easier to read by having the condition the same way as similarly done in sctp_v4_get_dst.

Change this to sctp_auth_create_key as it is the case everywhere else, so that we also can properly free it via sctp_auth_key_put.

2013-02-04sctp: sctp_close: fix release of bindings for deferred call_rcu'sDaniel Borkmann1-4/+5
It seems due to RCU usage, i.e. within SCTP's address binding list, a, say, ``behavioral change'' was introduced which does actually not conform to the RFC anymore. In particular consider the following (fictional) scenario to demonstrate this: do: Two SOCK_SEQPACKET-style sockets are opened (S1, S2) S1 is bound to 127.0.0.1, port 1024 [server] S2 is bound to 127.0.0.1, port 1025 [client] listen(2) is invoked on S1 From S2 we call one sendmsg(2) with msg.msg_name and msg.msg_namelen parameters set to the server's address S1, S2 are closed goto do The first pass of this loop passes successful, while the second round fails during binding of S1 (address still in use). What is happening? In the first round, the initial handshake is being done, and, at the time close(2) is called on S1, a non-graceful shutdown is performed via ABORT since in S1's receive queue an unprocessed packet is present, thus stating an error condition. This can be considered as a correct behavior. During close also all bound addresses are freed, thus nothing *must* be active anymore. In reference to RFC2960: After checking the Verification Tag, the receiving endpoint shall remove the association from its record, and shall report the termination to its upper layer. (9.1 Abort of an Association) Also, no half-open states are supported, thus after an ungraceful shutdown, we leave nothing behind. However, this seems not to be happening though. In a real-world scenario, this is exactly where it breaks the lksctp-tools functional test suite, *for instance*: ./test_sockopt test_sockopt.c 1 PASS : getsockopt(SCTP_STATUS) on a socket with no assoc test_sockopt.c 2 PASS : getsockopt(SCTP_STATUS) test_sockopt.c 3 PASS : getsockopt(SCTP_STATUS) with invalid associd test_sockopt.c 4 PASS : getsockopt(SCTP_STATUS) with NULL associd test_sockopt.c 5 BROK : bind: Address already in use The underlying problem is that sctp_endpoint_destroy() hasn't been triggered yet while the next bind attempt is being done. It will be triggered eventually (but too late) by sctp_transport_destroy_rcu() after one RCU grace period: sctp_transport_destroy() sctp_transport_destroy_rcu() ----. sctp_association_put() [*] <--+--> sctp_packet_free() sctp_association_destroy() [...] sctp_endpoint_put() skb->destructor sctp_endpoint_destroy() sctp_wfree() sctp_bind_addr_free() sctp_association_put() [*] Thus, we move out the condition with sctp_association_put() as well as the sctp_packet_free() invocation and the issue can be solved. We also better free the SCTP chunks first before putting the ref of the association. With this patch, the example above (which simulates a similar scenario as in the implementation of this test case) and therefore also the test suite run successfully through. Tested by myself.
