sch_red: fix red_calc_qavg_from_idle_time

2011-12-09T16:56:08+00:00

[ Upstream commit ea6a5d3b97b768561db6358f15e4c84ced0f4f7e ] Since commit a4a710c4a7490587 (pkt_sched: Change PSCHED_SHIFT from 10 to 6) it seems RED/GRED are broken. red_calc_qavg_from_idle_time() computes a delay in us units, but this delay is now 16 times bigger than real delay, so the final qavg result smaller than expected. Use standard kernel time services since there is no need to obfuscate them. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

inet: add a redirect generation id in inetpeer

2011-12-09T16:56:07+00:00

[ Upstream commit de68dca1816660b0d3ac89fa59ffb410007a143f ] Now inetpeer is the place where we cache redirect information for ipv4 destinations, we must be able to invalidate informations when a route is added/removed on host. As inetpeer is not yet namespace aware, this patch adds a shared redirect_genid, and a per inetpeer redirect_genid. This might be changed later if inetpeer becomes ns aware. Cache information for one inerpeer is valid as long as its redirect_genid has the same value than global redirect_genid.

udplite: fast-path computation of checksum coverage

2011-10-17T23:07:30+00:00

Commit 903ab86d195cca295379699299c5fc10beba31c7 of 1 March this year ("udp: Add lockless transmit path") introduced a new fast TX path that broke the checksum coverage computation of UDP-lite, which so far depended on up->len (only set if the socket is locked and 0 in the fast path). Fixed by providing both fast- and slow-path computation of checksum coverage. The latter can be removed when UDP(-lite)v6 also uses a lockless transmit path.

IPVS netns shutdown/startup dead-lock

2011-10-12T16:32:15+00:00

ip_vs_mutext is used by both netns shutdown code and startup and both implicit uses sk_lock-AF_INET mutex. cleanup CPU-1 startup CPU-2 ip_vs_dst_event() ip_vs_genl_set_cmd() sk_lock-AF_INET __ip_vs_mutex sk_lock-AF_INET __ip_vs_mutex * DEAD LOCK * A new mutex placed in ip_vs netns struct called sync_mutex is added. Comments from Julian and Simon added. This patch has been running for more than 3 month now and it seems to work. Ver. 3 IP_VS_SO_GET_DAEMON in do_ip_vs_get_ctl protected by sync_mutex instead of __ip_vs_mutex as sugested by Julian.

net: Handle different key sizes between address families in flow cache

2011-09-16T21:47:28+00:00

With the conversion of struct flowi to a union of AF-specific structs, some operations on the flow cache need to account for the exact size of the key. Signed-off-by: David Ward Signed-off-by: David S. Miller

sctp: deal with multiple COOKIE_ECHO chunks

2011-09-16T21:17:22+00:00

Attempt to reduce the number of IP packets emitted in response to single SCTP packet (2e3216cd) introduced a complication - if a packet contains two COOKIE_ECHO chunks and nothing else then SCTP state machine corks the socket while processing first COOKIE_ECHO and then loses the association and forgets to uncork the socket. To deal with the issue add new SCTP command which can be used to set association explictly. Use this new command when processing second COOKIE_ECHO chunk to restore the context for SCTP state machine. Signed-off-by: Max Matveev Signed-off-by: David S. Miller
