syncookies: Make sure ECN is disabled

2008-07-26T09:21:54Z

ecn_ok is not initialized when a connection is established by cookies. The cookie syn-ack never sets ECN, so ecn_ok must be set to 0. Spotted using ns-3/network simulation cradle simulator and valgrind. Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

inet{6}_request_sock: Init ->opt and ->pktopts in the constructor

2008-06-10T19:39:35Z

Wei Yongjun noticed that we may call reqsk_free on request sock objects where the opt fields may not be initialized, fix it by introducing inet_reqsk_alloc where we initialize ->opt to NULL and set ->pktopts to NULL in inet6_reqsk_alloc.

[Syncookies]: Add support for TCP options via timestamps.

2008-04-10T10:12:40Z

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. Feedback from Glenn Griffin: fix line indented with spaces, kill redundant if () Reviewed-by: Hagen Paul Pfeifer Signed-off-by: Florian Westphal Signed-off-by: David S. Miller

[TCP]: Shrink syncookie_secret by 8 byte.

2008-03-24T05:21:28Z

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. With fixes from Glenn Griffin. Signed-off-by: Florian Westphal Acked-by: Glenn Griffin Signed-off-by: David S. Miller

[TCP]: Add IPv6 support to TCP SYN cookies

2008-03-04T06:18:21Z

Updated to incorporate Eric's suggestion of using a per cpu buffer rather than allocating on the stack. Just a two line change, but will resend in it's entirety. Signed-off-by: Glenn Griffin Signed-off-by: YOSHIFUJI Hideaki

[TCP]: lower stack usage in cookie_hash() function

2008-03-04T06:18:21Z

400 bytes allocated on stack might be a litle bit too much. Using a per_cpu var is more friendly. Signed-off-by: Eric Dumazet Signed-off-by: YOSHIFUJI Hideaki
