As I can see from the code, two places (tcp_v6_syn_recv_sock and dccp_v6_request_recv_sock) that call this one already run with BHs disabled, so it's safe to call __inet_inherit_port there. Besides (in case I missed smth with code review) the calltrace tcp_v6_syn_recv_sock `- tcp_v4_syn_recv_sock `- __inet_inherit_port and the similar for DCCP are valid, but assumes BHs to be disabled.

Allow the use of SACK and window scaling when syncookies are used and the client supports tcp timestamps. Options are encoded into the timestamp sent in the syn-ack and restored from the timestamp echo when the ack is received. Based on earlier work by Glenn Griffin. This patch avoids increasing the size of structs by encoding TCP options into the least significant bits of the timestamp and by not using any 'timestamp offset'. The downside is that the timestamp sent in the packet after the synack will increase by several seconds. changes since v1: don't duplicate timestamp echo decoding function, put it into ipv4/syncookie.c and have ipv6/syncookies.c use it.

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.

This way we can remove TCP and DCCP specific versions of sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port sk->sk_prot->hash: inet_hash is directly used, only v6 need a specific version to deal with mapped sockets sk->sk_prot->unhash: both v4 and v6 use inet_hash directly struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so that inet_csk_get_port can find the per family routine. Now only the lookup routines receive as a parameter a struct inet_hashtable. With this we further reuse code, reducing the difference among INET transport protocols. Eventually work has to be done on UDP and SCTP to make them share this infrastructure and get as a bonus inet_diag interfaces so that iproute can be used with these protocols. net-2.6/net/ipv4/inet_hashtables.c: struct proto | +8 struct inet_connection_sock_af_ops | +8 2 structs changed __inet_hash_nolisten | +18 __inet_hash | -210 inet_put_port | +8 inet_bind_bucket_create | +1 __inet_hash_connect | -8 5 functions changed, 27 bytes added, 218 bytes removed, diff: -191 net-2.6/net/core/sock.c: proto_seq_show | +3 1 function changed, 3 bytes added, diff: +3 net-2.6/net/ipv4/inet_connection_sock.c: inet_csk_get_port | +15 1 function changed, 15 bytes added, diff: +15 net-2.6/net/ipv4/tcp.c: tcp_set_state | -7 1 function changed, 7 bytes removed, diff: -7 net-2.6/net/ipv4/tcp_ipv4.c: tcp_v4_get_port | -31 tcp_v4_hash | -48 tcp_v4_destroy_sock | -7 tcp_v4_syn_recv_sock | -2 tcp_unhash | -179 5 functions changed, 267 bytes removed, diff: -267 net-2.6/net/ipv6/inet6_hashtables.c: __inet6_hash | +8 1 function changed, 8 bytes added, diff: +8 net-2.6/net/ipv4/inet_hashtables.c: inet_unhash | +190 inet_hash | +242 2 functions changed, 432 bytes added, diff: +432 vmlinux: 16 functions changed, 485 bytes added, 492 bytes removed, diff: -7 /home/acme/git/net-2.6/net/ipv6/tcp_ipv6.c: tcp_v6_get_port | -31 tcp_v6_hash | -7 tcp_v6_syn_recv_sock | -9 3 functions changed, 47 bytes removed, diff: -47 /home/acme/git/net-2.6/net/dccp/proto.c: dccp_destroy_sock | -7 dccp_unhash | -179 dccp_hash | -49 dccp_set_state | -7 dccp_done | +1 5 functions changed, 1 bytes added, 242 bytes removed, diff: -241 /home/acme/git/net-2.6/net/dccp/ipv4.c: dccp_v4_get_port | -31 dccp_v4_request_recv_sock | -2 2 functions changed, 33 bytes removed, diff: -33 /home/acme/git/net-2.6/net/dccp/ipv6.c: dccp_v6_get_port | -31 dccp_v6_hash | -7 dccp_v6_request_recv_sock | +5 3 functions changed, 5 bytes added, 38 bytes removed, diff: -33 Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: NDavid S.

sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

This fixes scatterlist corruptions added by commit 68e3f5dd [CRYPTO] users: Fix up scatterlist conversion errors The issue is that the code calls sg_mark_end() which clobbers the sg_page() pointer of the final scatterlist entry. The first part fo the fix makes skb_to_sgvec() do __sg_mark_end(). After considering all skb_to_sgvec() call sites the most correct solution is to call __sg_mark_end() in skb_to_sgvec() since that is what all of the callers would end up doing anyways. I suspect this might have fixed some problems in virtio_net which is the sole non-crypto user of skb_to_sgvec(). Other similar sg_mark_end() cases were converted over to __sg_mark_end() as well. Arguably sg_mark_end() is a poorly named function because it doesn't just "mark", it clears out the page pointer as a side effect, which is what led to these bugs in the first place. The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable() and arguably it could be converted to __sg_mark_end() if only so that we can delete this confusing interface from linux/scatterlist.h Signed-off-by: NDavid S.

Based upon a report and initial patch by Peter Lieven. tcp4_md5sig_key and tcp6_md5sig_key need to start with the exact same members as tcp_md5sig_key. Because they are both cast to that type by tcp_v{4,6}_md5_do_lookup(). Unfortunately tcp{4,6}_md5sig_key use a u16 for the key length instead of a u8, which is what tcp_md5sig_key uses. This just so happens to work by accident on little-endian, but on big-endian it doesn't. Instead of casting, just place tcp_md5sig_key as the first member of the address-family specific structures, adjust the access sites, and kill off the ugly casts. Signed-off-by: NDavid S.

As discovered by Evegniy Polyakov, if we try to sendmsg after a connection reset, we can do incredibly stupid things. The core issue is that inet_sendmsg() tries to autobind the socket, but we should never do that for TCP. Instead we should just go straight into TCP's sendmsg() code which will do all of the necessary state and pending socket error checks. TCP's sendpage already directly vectors to tcp_sendpage(), so this merely brings sendmsg() in line with that. Signed-off-by: NDavid S. Miller <davem@davemloft.net>
