2005-11-20[NETFILTER]: fixed dependencies between modules related with ip_conntrackYasuyuki Kozakai
- IP_NF_CONNTRACK_MARK is bool and depends on only IP_NF_CONNTRACK which is tristate. If a variable depends on IP_NF_CONNTRACK_MARK and doesn't care about IP_NF_CONNTRACK, it can be y. This must be avoided. - IP_NF_CT_ACCT has same problem. - IP_NF_TARGET_CLUSTERIP also depends on IP_NF_MANGLE.

2005-11-20[PKT_SCHED]: sch_netem: correctly order packets to be sent simultaneouslyAndrea Bittau
If two packets were queued to be sent at the same time in the future, their order would be reversed. This would occur because the queue is traversed back to front, and a position is found by checking whether the new packet needs to be sent before the packet being examined. If the new packet is to be sent at the same time of a previous packet, it would end up before the old packet in the queue. This patch places packets in the correct order when they are queued to be sent at a same time in the future. Signed-off-by: Andrea Bittau <a.bittau@cs.ucl.ac.uk> Signed-off-by: David S.

2005-11-17[LLC]: Fix compiler warnings introduced by TX window scaling changes.David S. Miller
Noticed by Olaf Hering. The comparisons want a u8 here (the data type on the left-hand branch is a u8 structure member, and the constant on the right-hand branch is "~((u8) 128)"), but C turns it into an integer so we get: net/llc/llc_c_ac.c: In function `llc_conn_ac_inc_npta_value': net/llc/llc_c_ac.c:998: warning: comparison is always true due to limited range of data type net/llc/llc_c_ac.c:999: warning: large integer implicitly truncated to unsigned type Fix this up by explicitly recasting the right-hand branch constant into a "u8" once more.

2005-11-15[PATCH] knfsd: make sure nfsd doesn't hog a cpu foreverNeilBrown
Being kernel-threads, nfsd servers don't get pre-empted (depending on CONFIG). If there is a steady stream of NFS requests that can be served from cache, an nfsd thread may hold on to a cpu indefinitely, which isn't very friendly. So it is good to have a cond_resched in there (just before looking for a new request to serve), to make sure we play nice.

However, when responding to OOTB packets we already properly set the source address based on the information in the OOTB packet. So, if we we get to sctp_v4_get_saddr() without an association we can simply return.

2005-11-10[TCP]: receive buffer growth limiting with mixed MTUJohn Heffner
This is a patch for discussion addressing some receive buffer growing issues. This is partially related to the thread "Possible BUG in IPv4 TCP window handling..." last week. Specifically it addresses the problem of an interaction between rcvbuf moderation (receiver autotuning) and rcv_ssthresh. The problem occurs when sending small packets to a receiver with a larger MTU. (A very common case I have is a host with a 1500 byte MTU sending to a host with a 9k MTU.) In such a case, the rcv_ssthresh code is targeting a window size corresponding to filling up the current rcvbuf, not taking into account that the new rcvbuf moderation may increase the rcvbuf size. One hunk makes rcv_ssthresh use tcp_rmem[2] as the size target rather than rcvbuf. The other changes the behavior when it overflows its memory bounds with in-order data so that it tries to grow rcvbuf (the same as with out-of-order data). These changes should help my problem of mixed MTUs, and should also help the case from last week's thread I think. (In both cases though you still need tcp_rmem[2] to be set much larger than the TCP window.) One question is if this is too aggressive at trying to increase rcvbuf if it's under memory stress.
