2008-07-05net: Add STP demux layerPatrick McHardy
Add small STP demux layer for demuxing STP PDUs based on MAC address. This is needed to run both GARP and STP in parallel (or even load the modules) since both use LLC_SAP_BSPAN. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-05MIB: add struct net to UDP_INC_STATS_BHPavel Emelyanov
Two special cases here - one is rxrpc - I put init_net there explicitly, since we haven't touched this part yet. The second place is in __udp4_lib_rcv - we already have a struct net there, but I have to move its initialization above to make it ready at the "drop" label.

2008-07-05ipv4: remove static flush_delay variableDenis V. Lunev
flush delay is used as an external storage for net.ipv4.route.flush sysctl entry. It is write-only. The ctl_table->data for this entry is used once. Fix this case to point to the stack to remove global variable. Do this to avoid additional variable on struct net in the next patch.

2008-07-03tcp: de-bloat a bit with factoring NET_INC_STATS_BH outPavel Emelyanov
There are some places in TCP that select one MIB index to bump snmp statistics like this: if (<something>) NET_INC_STATS_BH(<some_id>); else if (<something_else>) NET_INC_STATS_BH(<some_other_id>); ... else NET_INC_STATS_BH(<default_id>); or in a more tricky but still similar way. On the other hand, this NET_INC_STATS_BH is a camouflaged increment of percpu variable, which is not that small. Factoring those cases out de-bloats 235 bytes on non-preemptible i386 config and drives parts of the code into 80 columns. add/remove: 0/0 grow/shrink: 0/7 up/down: 0/-235 (-235) function old new delta tcp_fastretrans_alert 1437 1424 -13 tcp_dsack_set 137 124 -13 tcp_xmit_retransmit_queue 690 676 -14 tcp_try_undo_recovery 283 265 -18 tcp_sacktag_write_queue 1550 1515 -35 tcp_update_reordering 162 106 -56 tcp_retransmit_timer 990 904 -86 Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

2008-06-27netlabel: Fix a problem when dumping the default IPv6 static labelsPaul Moore
There is a missing "!" in a conditional statement which is causing entries to be skipped when dumping the default IPv6 static label entries. This can be demonstrated by running the following: # netlabelctl unlbl add default address:::1 \ label:system_u:object_r:unlabeled_t:s0 # netlabelctl -p unlbl list ... you will notice that the entry for the IPv6 localhost address is not displayed but does exist (works correctly, causes collisions when attempting to add duplicate entries, etc.).

2008-06-27net/inet_lro: remove setting skb->ip_summed when not LRO-ableEli Cohen
When an SKB cannot be chained to a session, the current code attempts to "restore" its ip_summed field from lro_mgr->ip_summed. However, lro_mgr->ip_summed does not hold the original value; in fact, we'd better not touch skb->ip_summed since it is not modified by the code in the path leading to a failure to chain it. Also use a cleaer comment to the describe the ip_summed field of struct net_lro_mgr.

The problem is that while we work w/o the inet_frags.lock even read-locked the secret rebuild timer may occur (on another CPU, since BHs are still disabled in the inet_frag_find) and change the rnd seed for ipv4/6 fragments. It was caused by my patch fd9e63544cac30a34c951f0ec958038f0529e244 ([INET]: Omit double hash calculations in xxx_frag_intern) late in the 2.6.24 kernel, so this should probably be queued to -stable.

2008-06-27af_unix: fix 'poll for write'/connected DGRAM socketsRainer Weikusat
For n:1 'datagram connections' (eg /dev/log), the unix_dgram_sendmsg routine implements a form of receiver-imposed flow control by comparing the length of the receive queue of the 'peer socket' with the max_ack_backlog value stored in the corresponding sock structure, either blocking the thread which caused the send-routine to be called or returning EAGAIN. This routine is used by both SOCK_DGRAM and SOCK_SEQPACKET sockets. The poll-implementation for these socket types is datagram_poll from core/datagram.c. A socket is deemed to be writeable by this routine when the memory presently consumed by datagrams owned by it is less than the configured socket send buffer size. This is always wrong for PF_UNIX non-stream sockets connected to server sockets dealing with (potentially) multiple clients if the abovementioned receive queue is currently considered to be full. 'poll' will then return, indicating that the socket is writeable, but a subsequent write result in EAGAIN, effectively causing an (usual) application to 'poll for writeability by repeated send request with O_NONBLOCK set' until it has consumed its time quantum. The change below uses a suitably modified variant of the datagram_poll routines for both type of PF_UNIX sockets, which tests if the recv-queue of the peer a socket is connected to is presently considered to be 'full' as part of the 'is this socket writeable'-checking code. The socket being polled is additionally put onto the peer_wait wait queue associated with its peer, because the unix_dgram_recvmsg routine does a wake up on this queue after a datagram was received and the 'other wakeup call' is done implicitly as part of skb destruction, meaning, a process blocked in poll because of a full peer receive queue could otherwise sleep forever if no datagram owned by its socket was already sitting on this queue. Among this change is a small (inline) helper routine named 'unix_recvq_full', which consolidates the actual testing code (in three different places) into a single location.

2008-06-27tcp: fix for splice receive when used with software LROOctavian Purdila
If an skb has nr_frags set to zero but its frag_list is not empty (as it can happen if software LRO is enabled), and a previous tcp_read_sock has consumed the linear part of the skb, then __skb_splice_bits: (a) incorrectly reports an error and (b) forgets to update the offset to account for the linear part Any of the two problems will cause the subsequent __skb_splice_bits call (the one that handles the frag_list skbs) to either skip data, or, if the unadjusted offset is greater then the size of the next skb in the frag_list, make tcp_splice_read loop forever.
