2005-08-29[IPV4]: Prepare FIB core for RCU.Robert Olsson3-1/+24
* RCU versions of hlist_***_rcu * fib_alias partial rcu port just whats needed now. Signed-off-by: Robert Olsson <Robert.Olsson@data.slu.se> Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[IPV4]: Module export of ip_rcv() no longer needed.Ralf Baechle1-1/+0
With ip_rcv nowhere outside the IP stack being used anymore it's EXPORT_SYMBOL is not needed any longer either. Signed-off-by: Ralf Baechle DL5RB <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[AX25/NETROM/ROSE]: Kill net/ip.h inclusionRalf Baechle4-4/+0
All these are claiming to include <net/ip.h> to get ip_rcv() but in fact don't need the header at all, so away with the inclusion. Signed-off-by: Ralf Baechle DL5RB <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[AX25/NETROM]: Cleanup direct calls into IP stackRalf Baechle3-16/+7
Get rid of the calls to ip_rcv and arp_rcv which were layering violations anyway. With those being replaced by netif_rx, less parts of AX.25 and relatives depend on INET support actually being enabled. This also will make PF_PACKET sockets work for IP and ARP packets received over AX.25 and for IP packets over NET/ROM. Signed-off-by: Ralf Baechle DL5RB <ralf@linux-mips.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-29[IPV4]: FIB trie cleanupStephen Hemminger1-69/+31
This is a redo of earlier cleanup stuff: * replace DBG() macro with pr_debug() * get rid of duplicate extern's that are already in fib_lookup.h * use BUG_ON and WARN_ON * don't use BUG checks for null pointers where next statement would get a fault anyway * remove debug printout when rebalance causes deep tree * remove trailing blanks Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S.

2005-08-29[DCCP]: Introduce dccp_get_infoArnaldo Carvalho de Melo3-1/+70
And also hc_tx and hc_rx get_info functions for the CCIDs to fill in information that is specific to them. For now reusing struct tcp_info, later I'll try to figure out a better solution, for now its really nice to get this kind of info: [root@qemu ~]# ./ss -danemi State Recv-Q Send-Q Local Addr:Port Peer Addr:Port LISTEN 0 0 *:5001 *:* ino:628 sk:c1340040 mem:(r0,w0,f0,t0) cwnd:0 ssthresh:0 ESTAB 0 0 172.20.0.2:5001 172.20.0.1:32785 ino:629 sk:c13409a0 mem:(r0,w0,f0,t0) ts rto:1000 rtt:0.004/0 cwnd:0 ssthresh:0 rcv_rtt:61.377 This, for instance, shows that we're not congestion controlling ACKs, as the above output is in the ttcp receiving host, and ttcp is a one way app, i.e. the received never calls sendmsg, so ccid_hc_tx_send_packet is never called, so the TX half connection stays in TFRC_SSTATE_NO_SENT state and hctx_rtt is never calculated, stays with the value set in ccid3_hc_tx_init, 4us, as show above in milliseconds (0.004ms), upcoming patches will fix this. rcv_rtt seems sane tho, matching ping results :-) Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

2005-08-29[CCID]: Make ccid_hc_[rt]x_exit accept NULL argumentsArnaldo Carvalho de Melo1-2/+4

2005-08-29[DCCP]: Implement the CLOSING timerArnaldo Carvalho de Melo4-31/+46
So that we retransmit CLOSE/CLOSEREQ packets till they elicit an answer or we hit a timeout.

2005-08-29[DCCP]: Fix the timestamp optionsIan McDonald4-41/+79
This changes timestamp, timestamp echo, and elapsed time to use units of 10 usecs as per DCCP spec. This has been tested to verify that times are correct. Also fixed up length and used hton/ntoh more. Still to add in later patches: - actually use elapsed time to adjust RTT (commented out as was prior to this patch) - send options at times more closely following the spec (content is now correct) Signed-off-by: Ian McDonald <iam4@cs.waikato.ac.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com> Signed-off-by: David S.

2005-08-29[NET]: Implement SKB fast cloning.David S. Miller4-16/+98
Protocols that make extensive use of SKB cloning, for example TCP, eat at least 2 allocations per packet sent as a result. To cut the kmalloc() count in half, we implement a pre-allocation scheme wherein we allocate 2 sk_buff objects in advance, then use a simple reference count to free up the memory at the correct time. Based upon an initial patch by Thomas Graf and suggestions from Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net>
