ipv6: tcp: fix tcp_v6_conn_request()

2011-11-23T22:29:23+00:00

Since linux 2.6.26 (commit c6aefafb7ec6 : Add IPv6 support to TCP SYN
cookies), we can drop a SYN packet reusing a TIME_WAIT socket.

(As a matter of fact we fail to send the SYNACK answer)

As the client resends its SYN packet after a one second timeout, we
accept it, because first packet removed the TIME_WAIT socket before
being dropped.

This probably explains why nobody ever noticed or complained.

net: make the tcp and udp file_operations for the /proc stuff const

2011-11-01T21:56:14+00:00

the tcp and udp code creates a set of struct file_operations at runtime
while it can also be done at compile time, with the added benefit of then
having these file operations be const.

the trickiest part was to get the "THIS_MODULE" reference right; the naive
method of declaring a struct in the place of registration would not work
for this reason.

ipv6: tcp: fix TCLASS value in ACK messages sent from TIME_WAIT

2011-10-27T04:44:35+00:00

commit 66b13d99d96a (ipv4: tcp: fix TOS value in ACK messages sent from
TIME_WAIT) fixed IPv4 only.

This part is for the IPv6 side, adding a tclass param to ip6_xmit()

We alias tw_tclass and tw_tos, if socket family is INET6.

[ if sockets is ipv4-mapped, only IP_TOS socket option is used to fill
TOS field, TCLASS is not taken into account ]

tcp: md5: add more const attributes

2011-10-24T06:46:04+00:00

Now tcp_md5_hash_header() has a const tcphdr argument, we can add more
const attributes to callers.

tcp: add const qualifiers where possible

2011-10-21T09:22:42+00:00

Adding const qualifiers to pointers can ease code review, and spot some
bugs. It might allow compiler to optimize code further.

For example, is it legal to temporary write a null cksum into tcphdr
in tcp_md5_hash_header() ? I am afraid a sniffer could catch the
temporary null value...

tcp: properly handle md5sig_pool references

2011-10-05T03:31:24+00:00

tcp_v4_clear_md5_list() assumes that multiple tcp md5sig peers
only hold one reference to md5sig_pool. but tcp_v4_md5_do_add()
increases use count of md5sig_pool for each peer. This patch
makes tcp_v4_md5_do_add() only increases use count for the first
tcp md5sig peer.

ipv6: nullify ipv6_ac_list and ipv6_fl_list when creating new socket

2011-09-29T04:32:10+00:00

ipv6_ac_list and ipv6_fl_list from listening socket are inadvertently
shared with new socket created for connection.

tcp: unalias tcp_skb_cb flags and ip_dsfield

2011-09-27T06:20:08+00:00

struct tcp_skb_cb contains a "flags" field containing either tcp flags
or IP dsfield depending on context (input or output path)

Introduce ip_dsfield to make the difference clear and ease maintenance.
If later we want to save space, we can union flags/ip_dsfield
