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 ] Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipv6: make fragment identifications less predictable

2011-07-22T04:25:58+00:00

IPv6 fragment identification generation is way beyond what we use for IPv4 : It uses a single generator. Its not scalable and allows DOS attacks. Now inetpeer is IPv6 aware, we can use it to provide a more secure and scalable frag ident generator (per destination, instead of system wide) This patch : 1) defines a new secure_ipv6_id() helper 2) extends inet_getid() to provide 32bit results 3) extends ipv6_select_ident() with a new dest parameter Reported-by: Fernando Gont Signed-off-by: Eric Dumazet Signed-off-by: David S.

ipv6: reduce per device ICMP mib sizes

2011-05-19T20:21:22+00:00

ipv6 has per device ICMP SNMP counters, taking too much space because they use percpu storage. needed size per device is : (512+4)*sizeof(long)*number_of_possible_cpus*2 On a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of memory per ipv6 enabled network device, taken in vmalloc pool. Since ICMP messages are rare, just use shared counters (atomic_long_t) Per network space ICMP counters are still using percpu memory, we might also convert them to shared counters in a future patch.

net: Remove KERNEL cpp checks from include/net

2011-04-24T17:54:56+00:00

These header files are never installed to user consumption, so any __KERNEL__ cpp checks are superfluous. Projects should also not copy these files into their userland utility sources and try to use them there. If they insist on doing so, the onus is on them to sanitize the headers as needed.

inet: constify ip headers and in6_addr

2011-04-22T18:04:14+00:00

Add const qualifiers to structs iphdr, ipv6hdr and in6_addr pointers where possible, to make code intention more obvious. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

ipv6: Convert to use flowi6 where applicable.

xfrm: Handle blackhole route creation via afinfo.

2011-03-01T22:59:04+00:00

That way we don't have to potentially do this in every xfrm_lookup() caller. Signed-off-by: David S. Miller

ipv6: Normalize arguments to ip6_dst_blackhole().

2011-03-01T22:45:33+00:00

Return a dst pointer which is potentitally error encoded. Don't pass original dst pointer by reference, pass a struct net instead of a socket, and elide the flow argument since it is unnecessary. Signed-off-by: David S. Miller

ipv6: Change final dst lookup arg name to "can_sleep"

2011-03-01T22:32:04+00:00

Since it indicates whether we are invoked from a sleepable context or not. Signed-off-by: David S. Miller
