Implement the RFC 5691 mitigation against Blind Reset attack using RST bit. Idea is to validate incoming RST sequence, to match RCV.NXT value, instead of previouly accepted window : (RCV.NXT <= SEG.SEQ < RCV.NXT+RCV.WND) If sequence is in window but not an exact match, send a "challenge ACK", so that the other part can resend an RST with the appropriate sequence. Add a new sysctl, tcp_challenge_ack_limit, to limit number of challenge ACK sent per second. Add a new SNMP counter to count number of challenge acks sent. (netstat -s | grep TCPChallengeACK) Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Kiran Kumar Kella <kkiran@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Typically, the return value desired for the failure of a function with an integer return value is a negative integer. In these cases, the return value is sometimes a negative integer and sometimes 0, due to a subsequent initialization of the return variable within the loop. A simplified version of the semantic match that finds this problem is: (http://coccinelle.lip6.fr/) //<smpl> @r exists@ identifier ret; position p; constant C; expression e1,e3,e4; statement S; @@ ret = -C ... when != ret = e3 when any if@p (...)

netem does an early orphaning of skbs. Doing so breaks TCP Small Queue or any mechanism relying on socket sk_wmem_alloc feedback. Ideally, we should perform this orphaning after the rate module and before the delay module, to mimic what happens on a real link : skb orphaning is indeed normally done at TX completion, before the transit on the link. +-------+ +--------+ +---------------+ +-----------------+ + Qdisc +---> Device +--> TX completion +--> links / hops +-> + + + xmit + + skb orphaning + + propagation + +-------+ +--------+ +---------------+ +-----------------+ < rate limiting > < delay, drops, reorders > If netem is used without delay feature (drops, reorders, rate limiting), then we should avoid early skb orphaning, to keep pressure on sockets as long as packets are still in qdisc queue. Ideally, netem should be refactored to implement delay module as the last stage. Current algorithm merges the two phases (rate limiting + delay) so its not correct.

skb_fill_rx_data() pulls 64 byte of data in skb->data Its too much for TCP (with no options) on IPv4, as total size of headers is 14 + 40 = 54 This means tcp stack and splice() are suboptimal, since tcp payload is in part in tcp->data, and in part in skb frag.

The hash size is doubled when it needs to grow and compared against hash_max. The >= comparison will limit the hash table size to half of what is expected i.e. the default 512 hash_max will not allow the hash table to grow larger than 256. Also print the hash table limit instead of the desirable size when the limit is reached. Signed-off-by: NThomas Graf <tgraf@suug.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Userspace implementations of network routing protocols sometimes need to tell RA-originated IPv6 routes from other kernel routes to make proper routing decisions. This makes most sense for RA routes with nexthops, namely, default routes and Route Information routes. The intended mean of preserving RA route origin in a netlink message is through indicating RTPROT_RA as protocol code. Function rt6_fill_node() tried to do that for default routes, but its test condition was taken wrong. This change is modeled after the original mailing list posting by Jeff Haran. It fixes the test condition for default route case and sets the same behaviour for Route Information case (both types use nexthops). Handling of the 3rd RA route type, Prefix Information, is left unchanged, as it stands for interface connected routes (without nexthops).

Lenght field should be encoded using big endian byte order, such as intend in the specs. As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues.
