2009-06-29xfrm: use xfrm_addr_cmp() instead of compare addresses directlyWei Yongjun1-49/+8

2009-04-27xfrm: wrong hash value for temporary SANicolas Dichtel1-3/+3
When kernel inserts a temporary SA for IKE, it uses the wrong hash value for dst list. Two hash values were calcultated before: one with source address and one with a wildcard source address.

2009-03-27xfrm: spin_lock() should be spin_unlock() in xfrm_state.cChuck Ebbert1-1/+1
spin_lock() should be spin_unlock() in xfrm_state_walk_done(). caused by: commit 12a169e7d8f4b1c95252d8b04ed0f1033ed7cfe2 "ipsec: Put dumpers on the dump list" Reported-by: Marc Milgram <mmilgram@redhat.com> Signed-off-by: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: David S.

2009-03-13xfrm: Fix xfrm_state_find() wrt. wildcard source address.David S. Miller1-32/+58
The change to make xfrm_state objects hash on source address broke the case where such source addresses are wildcarded. Fix this by doing a two phase lookup, first with fully specified source address, next using saddr wildcarded. Reported-by: Nicolas Dichtel <nicolas.dichtel@dev.6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-20Revert "xfrm: For 32/64 compatability wrt. xfrm_usersa_info"David S. Miller1-9/+2
This reverts commit fc8c7dc1b29560c016a67a34ccff32a712b5aa86. As indicated by Jiri Klimes, this won't work. These numbers are not only used the size validation, they are also used to locate attributes sitting after the message. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-11ipcomp: Remove spurious truesize increaseHerbert Xu1-1/+0
When I made ipcomp use frags, I forgot to take out the original truesize update that was added for pskb_expand_head. As we no longer expand the head of skb, that update should have been removed. This bug is not related to the truesize warnings since we only made it bigger than what it should've been. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2008-12-04xfrm: Accept ESP packets regardless of UDP encapsulation modeMartin Willi1-5/+0
From: Martin Willi <martin@strongswan.org> An IPsec node speaking IKEv2 MUST accept incoming UDP encapsulated ESP packets, even if no NAT situation is detected. This is important if MOBIKE is in use. Some implementation keep the encapsulation mode if they move out of a NAT situation. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-03xfrm: Fix kernel panic when flush and dump SPD entriesWei Yongjun1-0/+1
After flush the SPD entries, dump the SPD entries will cause kernel painc. Used the following commands to reproduct: - echo 'spdflush;' | setkey -c - echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \ ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\ spddump;' | setkey -c - echo 'spdflush; spddump;' | setkey -c - echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \ ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\ spddump;' | setkey -c This is because when flush the SPD entries, the SPD entry is not remove from the list.

2008-11-25netns xfrm: per-netns sysctlsAlexey Dobriyan5-19/+100
Make net.core.xfrm_aevent_etime net.core.xfrm_acq_expires net.core.xfrm_aevent_rseqth net.core.xfrm_larval_drop sysctls per-netns. For that make net_core_path[] global, register it to prevent two /proc/net/core antries and change initcall position -- xfrm_init() is called from fs_initcall, so this one should be fs_initcall at least.
