the first u32 copied from syncookie_secret is overwritten by the minute-counter four lines below. After adjusting the destination address, the size of syncookie_secret can be reduced accordingly. AFAICS, the only other user of syncookie_secret[] is the ipv6 syncookie support. Because ipv6 syncookies only grab 44 bytes from syncookie_secret[], this shouldn't affect them in any way.

Sorry for the patch sequence confusion :| but I found that the similar thing can be done for raw sockets easily too late. Expand the proto.h union with the raw_hashinfo member and use it in raw_prot and rawv6_prot. This allows to drop the protocol specific versions of hash and unhash callbacks.

After this we have only udp_lib_get_port to get the port and two stubs for ipv4 and ipv6. No difference in udp and udplite except for initialized h.udp_hash member. I tried to find a graceful way to drop the only difference between udp_v4_get_port and udp_v6_get_port (i.e. the rcv_saddr comparison routine), but adding one more callback on the struct proto didn't appear such :( Maybe later.

Inspired by the commit ab1e0a13 ([SOCK] proto: Add hashinfo member to struct proto) from Arnaldo, I made similar thing for UDP/-Lite IPv4 and -v6 protocols. The result is not that exciting, but it removes some levels of indirection in udpxxx_get_port and saves some space in code and text. The first step is to union existing hashinfo and new udp_hash on the struct proto and give a name to this union, since future initialization of tcpxxx_prot, dccp_vx_protinfo and udpxxx_protinfo will cause gcc warning about inability to initialize anonymous member this way.

Change TCP_DEFER_ACCEPT implementation so that it transitions a connection to ESTABLISHED after handshake is complete instead of leaving it in SYN-RECV until some data arrvies. Place connection in accept queue when first data packet arrives from slow path. Benefits: - established connection is now reset if it never makes it to the accept queue - diagnostic state of established matches with the packet traces showing completed handshake - TCP_DEFER_ACCEPT timeouts are expressed in seconds and can now be enforced with reasonable accuracy instead of rounding up to next exponential back-off of syn-ack retry.

Commits f40c81 ([NETNS][IPV4] tcp - make proc handle the network namespaces) and a91275 ([NETNS][IPV6] udp - make proc handle the network namespace) both introduced bad checks on sockets and tw buckets to belong to proper net namespace. I.e. when checking for socket to belong to given net and family the do { sk = sk_next(sk); } while (sk && sk->sk_net != net && sk->sk_family != family); constructions were used. This is wrong, since as soon as the sk->sk_net fits the net the socket is immediately returned, even if it belongs to other family. As the result four /proc/net/(udp|tcp)[6] entries show wrong info. The udp6 entry even oopses when dereferencing inet6_sk(sk) pointer: static void udp6_sock_seq_show(struct seq_file *seq, struct sock *sp, int bucket) { ... struct ipv6_pinfo *np = inet6_sk(sp); ... dest = &np->daddr; /* will be NULL for AF_INET sockets */ ... seq_printf(... dest->s6_addr32[0], dest->s6_addr32[1], dest->s6_addr32[2], dest->s6_addr32[3], ...

Update: My mailer ate one of Jarek's feedback mails... Fixed the parameter in netif_set_gso_max_size() to be u32, not u16. Fixed the whitespace issue due to a patch import botch. Changed the types from u32 to unsigned int to be more consistent with other variables in the area. Also brought the patch up to the latest net-2.6.26 tree. Update: Made gso_max_size container 32 bits, not 16. Moved the location of gso_max_size within netdev to be less hotpath. Made more consistent names between the sock and netdev layers, and added a define for the max GSO size. Update: Respun for net-2.6.26 tree. Update: changed max_gso_frame_size and sk_gso_max_size from signed to unsigned - thanks Stephen! This patch adds the ability for device drivers to control the size of the TSO frames being sent to them, per TCP connection. By setting the netdevice's gso_max_size value, the socket layer will set the GSO frame size based on that value. This will propogate into the TCP layer, and send TSO's of that size to the hardware. This can be desirable to help tune the bursty nature of TSO on a per-adapter basis, where one may have 1 GbE and 10 GbE devices coexisting in a system, one running multiqueue and the other not, etc. This can also be desirable for devices that cannot support full 64 KB TSO's, but still want to benefit from some level of segmentation offloading.

When selecting a new window, tcp_select_window() tries not to shrink the offered window by using the maximum of the remaining offered window size and the newly calculated window size. The newly calculated window size is always a multiple of the window scaling factor, the remaining window size however might not be since it depends on rcv_wup/rcv_nxt. This means we're effectively shrinking the window when scaling it down. The dump below shows the problem (scaling factor 2^7): - Window size of 557 (71296) is advertised, up to 3111907257: IP 172.2.2.3.33000 > 172.2.2.2.33000: . ack 3111835961 win 557 <...> - New window size of 514 (65792) is advertised, up to 3111907217, 40 bytes below the last end: IP 172.2.2.3.33000 > 172.2.2.2.33000: . 3113575668:3113577116(1448) ack 3111841425 win 514 <...> The number 40 results from downscaling the remaining window: 3111907257 - 3111841425 = 65832 65832 / 2^7 = 514 65832 % 2^7 = 40 If the sender uses up the entire window before it is shrunk, this can have chaotic effects on the connection. When sending ACKs, tcp_acceptable_seq() will notice that the window has been shrunk since tcp_wnd_end() is before tp->snd_nxt, which makes it choose tcp_wnd_end() as sequence number. This will fail the receivers checks in tcp_sequence() however since it is before it's tp->rcv_wup, making it respond with a dupack. If both sides are in this condition, this leads to a constant flood of ACKs until the connection times out. Make sure the window is never shrunk by aligning the remaining window to the window scaling factor. Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S.
