2007-05-04[SCTP]: Set assoc_id correctly during INIT collision.Vlad Yasevich
During the INIT/COOKIE-ACK collision cases, it's possible to get into a situation where the association id is not yet set at the time of the user event generation. As a result, user events have an association id set to 0 which will confuse applications. This happens if we hit case B of duplicate cookie processing. In the particular example found and provided by Oscar Isaula <Oscar.Isaula@motorola.com>, flow looks like this: A B ---- INIT-------> (lost) <---------INIT------ ---- INIT-ACK---> <------ Cookie ECHO When the Cookie Echo is received, we end up trying to update the association that was created on A as a result of the (lost) INIT, but that association doesn't have the ID set yet.

2007-04-25[NET]: cleanup extra semicolonsStephen Hemminger
Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals. Most commonly is a bogus semicolon after: switch() { } Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SCTP]: Implement sac_info field in SCTP_ASSOC_CHANGE notification.Vlad Yasevich
As stated in the sctp socket api draft: sac_info: variable If the sac_state is SCTP_COMM_LOST and an ABORT chunk was received for this association, sac_info[] contains the complete ABORT chunk as defined in the SCTP specification RFC2960 [RFC2960] section 3.3.7. We now save received ABORT chunks into the sac_info field and pass that to the user. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-01-30[SCTP]: Force update of the rto when processing HB-ACKVlad Yasevich
When processing a HEARTBEAT-ACK it's possible that the transport rto timers will not be updated because a prior T3-RTX processing would have cleared the rto_pending flag on the transport. However, if we received a valid HEARTBEAT-ACK, we want to force update the rto variables, so re-set the rto_pending flag before calling sctp_transport_update_rto().

2007-01-23[SCTP]: Fix SACK sequence during shutdownVlad Yasevich
Currently, when association enters SHUTDOWN state,the implementation will SACK any DATA first and then transmit the SHUTDOWN chunk. This is against the order required by 2960bis spec. SHUTDOWN must always be first, followed by SACK. This change forces this order and also enables bundling.

2006-12-02[SCTP]: Switch ->cmp_addr() and sctp_cmp_addr_exact() to net-endian.Al Viro
instances of ->cmp_addr() are fine with switching both arguments to net-endian; callers other than in sctp_cmp_addr_exact() (both as ->cmp_addr(...) and direct calls of instances) adjusted; sctp_cmp_addr_exact() switched to net-endian itself and adjustment is done in its callers Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[SCTP]: Beginning of conversion to net-endian for embedded sctp_addr.Al Viro
Part 1: rename sctp_chunk->source, sctp_sockaddr_entry->a, sctp_transport->ipaddr and sctp_transport->saddr (to ..._h) The next patch will reintroduce these fields and keep them as net-endian mirrors of the original (renamed) ones. Split in two patches to make sure that we hadn't forgotten any instanes. Later in the series we'll eliminate uses of host-endian variants (basically switching users to net-endian counterparts as we progress through that mess). Then host-endian ones will die. Other embedded host-endian sctp_addr will be easier to switch directly, so we leave them alone for now. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
