* ipsec: Put dumpers on the dump listHerbert Xu2008-10-011-73/+36
| | | | | | | | | | | | | | | | | | | | | | | 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 Xu2008-09-221-9/+30
| | | | | | | | | | | | | | | | | | 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 Xu2008-09-091-13/+39
| | | | | | | | | | | | | | | | | 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. Miller2008-09-021-9/+23
| | | | | | | | | | | | | | 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.

The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future.

This is achieved adding the entries to one more list which is used solely for walking the entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a number of new IPsec audit events to meet the auditing requirements of RFC4303. This includes audit hooks for the following events: * Could not find a valid SA [sections 2.1, 3.4.2] . xfrm_audit_state_notfound() . xfrm_audit_state_notfound_simple() * Sequence number overflow [section 3.3.3] . xfrm_audit_state_replay_overflow() * Replayed packet [section 3.4.3] . xfrm_audit_state_replay() * Integrity check failure [sections 3.4.4.1, 3.4.4.2] . xfrm_audit_state_icvfail() While RFC4304 deals only with ESP most of the changes in this patch apply to IPsec in general, i.e. both AH and ESP. The one case, integrity check failure, where ESP specific code had to be modified the same was done to the AH code for the sake of consistency.

| | | | | | | | | | | | | | The _find calls calculate the hash value using the xfrm_state_hmask, without the xfrm_state_lock. But the value of this mask can change in the _resize call under the state_lock, so we risk to fail in finding the desired entry in hash.

| | | | | | | | | | | | | | | | | | | This patch adds a new field to xfrm states called inner_mode. The existing mode object is renamed to outer_mode. This is the first part of an attempt to fix inter-family transforms. As it is we always use the outer family when determining which mode to use. As a result we may end up shoving IPv4 packets into netfilter6 and vice versa. What we really want is to use the inner family for the first part of outbound processing and the outer family for the second part. For inbound processing we'd use the opposite pairing. I've also added a check to prevent silly combinations such as transport mode with inter-family transforms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [IPSEC]: Store afinfo pointer in xfrm_modeHerbert Xu2007-10-171-9/+17
| | | | | | | | | | | | | | | | | It is convenient to have a pointer from xfrm_state to address-specific functions such as the output function for a family. Currently the address-specific policy code calls out to the xfrm state code to get those pointers when we could get it in an easier way via the state itself. This patch adds an xfrm_state_afinfo to xfrm_mode (since they're address-specific) and changes the policy code to use it. I've also added an owner field to do reference counting on the module providing the afinfo even though it isn't strictly necessary today since IPv6 can't be unloaded yet.

| | | | | | | | | | | | | | The type and mode maps are only used by SAs, not policies. So it makes sense to move them from xfrm_policy.c into xfrm_state.c. This also allows us to mark xfrm_get_type/xfrm_put_type/xfrm_get_mode/xfrm_put_mode as static. The only other change I've made in the move is to get rid of the casts on the request_module call for types. They're unnecessary because C will promote them to ints anyway.

* [IPSEC]: Move common code into xfrm_alloc_spiHerbert Xu2007-10-101-6/+20
| | | | | | | | | | | | | | | | | This patch moves some common code that conceptually belongs to the xfrm core from af_key/xfrm_user into xfrm_alloc_spi. In particular, the spin lock on the state is now taken inside xfrm_alloc_spi. Previously it also protected the construction of the response PF_KEY/XFRM messages to user-space. This is inconsistent as other identical constructions are not protected by the state lock. This is bad because they in fact should be protected but only in certain spots (so as not to hold the lock for too long which may cause packet drops). The SPI byte order conversion has also been moved. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
