* ipsec: Put dumpers on the dump listHerbert Xu2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | Herbert Xu came up with the idea and the original patch to make xfrm_state dump list contain also dumpers: As it is we go to extraordinary lengths to ensure that states don't go away while dumpers go to sleep. It's much easier if we just put the dumpers themselves on the list since they can't go away while they're going. I've also changed the order of addition on new states to prevent a never-ending dump. Timo Teräs improved the patch to apply cleanly to latest tree, modified iteration code to be more readable by using a common struct for entries in the list, implemented the same idea for xfrm_policy dumping and moved the af_key specific "last" entry caching to af_key.

* | ipsec: Fix xfrm_state_walk raceHerbert Xu2008-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discovered by Timo Teräs, the currently xfrm_state_walk scheme is racy because if a second dump finishes before the first, we may free xfrm states that the first dump would walk over later. This patch fixes this by storing the dumps in a list in order to calculate the correct completion counter which cures this problem. I've expanded netlink_cb in order to accomodate the extra state related to this. It shouldn't be a big deal since netlink_cb is kmalloced for each dump and we're just increasing it by 4 or 8 bytes.

* | ipsec: Use RCU-like construct for saved state within a walkHerbert Xu2008-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we save states within a walk we need synchronisation so that the list the saved state is on doesn't disappear from under us. As it stands this is done by keeping the state on the list which is bad because it gets in the way of the management of the state life-cycle. An alternative is to make our own pseudo-RCU system where we use counters to indicate which state can't be freed immediately as it may be referenced by an ongoing walk when that resumes.

* ipsec: Fix deadlock in xfrm_state management.David S. Miller2008-09-02
| | | | | | | | | | | | | | Ever since commit 4c563f7669c10a12354b72b518c2287ffc6ebfb3 ("[XFRM]: Speed up xfrm_policy and xfrm_state walking") it is illegal to call __xfrm_state_destroy (and thus xfrm_state_put()) with xfrm_state_lock held. If we do, we'll deadlock since we have the lock already and __xfrm_state_destroy() tries to take it again. Fix this by pushing the xfrm_state_put() calls after the lock is dropped.

* | [IPSEC]: Use digest_null directly for authHerbert Xu2008-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously digest_null had no setkey function which meant that we used hmac(digest_null) for IPsec since IPsec always calls setkey. Now that digest_null has a setkey we no longer need to do that. In fact when only confidentiality is specified for ESP we already use digest_null directly. However, when the null algorithm is explicitly specified by the user we still opt for hmac(digest_null). This patch removes this discrepancy. I have not added a new compat name for it because by chance it wasn't actualy possible for the user to specify the name hmac(digest_null) due to a key length check in xfrm_user (which I found out when testing that compat name :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [IPSEC]: Fix catch-22 with algorithm IDs above 31Herbert Xu2008-04-22
| | | | | | | | | | | | | | | | | | | | | | | As it stands it's impossible to use any authentication algorithms with an ID above 31 portably. It just happens to work on x86 but fails miserably on ppc64. The reason is that we're using a bit mask to check the algorithm ID but the mask is only 32 bits wide. After looking at how this is used in the field, I have concluded that in the long term we should phase out state matching by IDs because this is made superfluous by the reqid feature. For current applications, the best solution IMHO is to allow all algorithms when the bit masks are all ~0. The following patch does exactly that. This bug was identified by IBM when testing on the ppc64 platform using the NULL authentication algorithm which has an ID of 251.
