* [AX25/NETROM]: Cleanup direct calls into IP stackRalf Baechle2005-08-303-16/+7Star
| | | | | | | | | | | 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.

* [DCCP]: Introduce dccp_get_infoArnaldo Carvalho de Melo2005-08-303-1/+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.

* [NET]: Implement SKB fast cloning.David S. Miller2005-08-302-12/+74
| | | | | | | | | | | | | | | | | 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.

* [NETLINK]: Fix module refcounting problemsPatrick McHardy2005-08-301-65/+35Star
| | | | | | | | | | | | | | | | | Use-after-free: the struct proto_ops containing the module pointer is freed when a socket with pid=0 is released, which besides for kernel sockets is true for all unbound sockets. Module refcount leak: when the kernel socket is closed before all user sockets have been closed the proto_ops struct for this family is replaced by the generic one and the module refcount can't be dropped. The second problem can't be solved cleanly using module refcounting in the generic socket code, so this patch adds explicit refcounting to netlink_create/netlink_release.
