2008-02-05[SCTP]: Stop claiming that this is a "reference implementation"Vlad Yasevich
I was notified by Randy Stewart that lksctp claims to be "the reference implementation". First of all, "the refrence implementation" was the original implementation of SCTP in usersapce written ty Randy and a few others. Second, after looking at the definiton of 'reference implementation', we don't really meet the requirements. Signed-off-by: Vlad Yasevich <>
2008-01-28[NET]: Convert init_timer into setup_timerPavel Emelyanov
Many-many code in the kernel initialized the timer->function and timer->data together with calling init_timer(timer). There is already a helper for this. Use it for networking code. The patch is HUGE, but makes the code 130 lines shorter (98 insertions(+), 228 deletions(-)). Signed-off-by: Pavel Emelyanov <> Acked-by: Arnaldo Carvalho de Melo <> Signed-off-by: David S. Miller <>
2007-11-07SCTP: Fix difference cases of retransmit.Vlad Yasevich
Commit d0ce92910bc04e107b2f3f2048f07e94f570035d broke several retransmit cases including fast retransmit. The reason is that we should only delay by rto while doing retranmists as a result of a timeout. Retransmit as a result of path mtu discover, fast retransmit, or other evernts that should trigger immidiate retransmissions got broken. Also, since rto is doubled prior to marking of packets elegable for retransmission, we never marked correct chunks anyway. The fix is provide a reason for a given retransmission so that we can mark chunks appropriately and to save the old rto value to do comparisons against. All regressions tests passed with this code.

2007-06-13[SCTP] Don't disable PMTU discovery when mtu is smallVlad Yasevich
Right now, when we receive a mtu estimate smaller then minim threshold in the ICMP message, we disable the path mtu discovery on the transport. This leads to the never increasing sctp fragmentation point even when the real path mtu has increased. Signed-off-by: Vlad Yasevich <>
2007-06-13[SCTP] Update pmtu handling to be similar to tcpVlad Yasevich

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 <> Signed-off-by: David S. Miller <>
2007-03-22[SCTP]: Correctly reset ssthresh when restarting associationVlad Yasevich
Reset ssthresh to the correct value (peer's a_rwnd) when restarting association. Signed-off-by: Vlad Yasevich <> Signed-off-by: David S. Miller <>
2007-03-20[SCTP]: Reset some transport and association variables on restartVlad Yasevich
If the association has been restarted, we need to reset the transport congestion variables as well as accumulated error counts and CACC variables. If we do not, the association will use the wrong values and may terminate prematurely. This was found with a scenario where the peer restarted the association when lksctp was in the last HB timeout for its association. The restart happened, but the error counts have not been reset and when the timeout occurred, a newly restarted association was terminated due to excessive retransmits.

2006-09-22[SCTP]: Remove multiple levels of msecs to jiffies conversions.Vladislav Yasevich
The SCTP sysctl entries are displayed in milliseconds, but stored internally in jiffies. This results in multiple levels of msecs to jiffies conversion and as a result produces a truncation error. This patch makes things consistent in that we store and display defaults in milliseconds and only convert once for use by association. This patch also adds some sane min/max values so that we don't go off the deep end. Signed-off-by: Vladislav Yasevich <> Signed-off-by: Sridhar Samudrala <> Signed-off-by: David S. Miller <>

2006-01-17[SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs.Vlad Yasevich

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.

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!
