* [XFRM]: Display the audited SPI value in host byte order.Paul Moore2007-12-141-4/+6
| | | | | | | | | | Currently the IPsec protocol SPI values are written to the audit log in network byte order which is different from almost all other values which are recorded in host byte order. This patch corrects this inconsistency by writing the SPI values to the audit record in host byte order. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

* [IPSEC]: Fix potential dst leak in xfrm_lookupHerbert Xu2007-12-111-3/+6
| | | | | | | | | | | If we get an error during the actual policy lookup we don't free the original dst while the caller expects us to always free the original dst in case of error.

* [IPSEC]: Fix uninitialised dst warning in __xfrm_lookupHerbert Xu2007-11-301-0/+1
| | | | | | | | | | | | | | | | | | | Andrew Morton reported that __xfrm_lookup generates this warning: net/xfrm/xfrm_policy.c: In function '__xfrm_lookup': net/xfrm/xfrm_policy.c:1449: warning: 'dst' may be used uninitialized in this function This is because if policy->action is of an unexpected value then dst will not be initialised. Of course, in practice this should never happen since the input layer xfrm_user/af_key will filter out all illegal values. But the compiler doesn't know that of course. So this patch fixes this by taking the conservative approach and treat all unknown actions the same as a blocking action. Thanks to Andrew for finding this and providing an initial fix.

* [XFRM]: Fix leak of expired xfrm_statesPatrick McHardy2007-11-271-1/+1
| | | | | | | | | | | The xfrm_timer calls __xfrm_state_delete, which drops the final reference manually without triggering destruction of the state. Change it to use xfrm_state_put to add the state to the gc list when we're dropping the last reference. The timer function may still continue to use the state safely since the final destruction does a del_timer_sync().

* [IPSEC]: Temporarily remove locks around copying of non-atomic fieldsHerbert Xu2007-11-261-2/+0
| | | | | | | | | | | | | | | | | | | | The change 050f009e16f908932070313c1745d09dc69fd62b [IPSEC]: Lock state when copying non-atomic fields to user-space caused a regression. Ingo Molnar reports that it causes a potential dead-lock found by the lock validator as it tries to take x->lock within xfrm_state_lock while numerous other sites take the locks in opposite order. For 2.6.24, the best fix is to simply remove the added locks as that puts us back in the same state as we've been in for years. For later kernels a proper fix would be to reverse the locking order for every xfrm state user such that if x->lock is taken together with xfrm_state_lock then it is to be taken within it.

* [IPSEC]: Rename mode to outer_mode and add inner_modeHerbert Xu2007-10-173-7/+17
| | | | | | | | | | | | | | | | | | | 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.

* [IPSEC]: Add missing BEET checksHerbert Xu2007-10-172-3/+5
| | | | | | | | | | | | | | | | | | Currently BEET mode does not reinject the packet back into the stack like tunnel mode does. Since BEET should behave just like tunnel mode this is incorrect. This patch fixes this by introducing a flags field to xfrm_mode that tells the IPsec code whether it should terminate and reinject the packet back into the stack. It then sets the flag for BEET and tunnel mode. I've also added a number of missing BEET checks elsewhere where we check whether a given mode is a tunnel or not.

* [IPSEC]: Move type and mode map into xfrm_state.cHerbert Xu2007-10-172-173/+170
| | | | | | | | | | | | | | 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]: Fix length check in xfrm_parse_spiHerbert Xu2007-10-171-1/+4
| | | | | | | | | | | Currently xfrm_parse_spi requires there to be 16 bytes for AH and ESP. In contrived cases there may not actually be 16 bytes there since the respective header sizes are less than that (8 and 12 currently). This patch changes the test to use the actual header length instead of 16. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: make netlink user -> kernel interface synchroniousDenis V. Lunev2007-10-101-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch make processing netlink user -> kernel messages synchronious. This change was inspired by the talk with Alexey Kuznetsov about current netlink messages processing. He says that he was badly wrong when introduced asynchronious user -> kernel communication. The call netlink_unicast is the only path to send message to the kernel netlink socket. But, unfortunately, it is also used to send data to the user. Before this change the user message has been attached to the socket queue and sk->sk_data_ready was called. The process has been blocked until all pending messages were processed. The bad thing is that this processing may occur in the arbitrary process context. This patch changes nlk->data_ready callback to get 1 skb and force packet processing right in the netlink_unicast. Kernel -> user path in netlink_unicast remains untouched. EINTR processing for in netlink_run_queue was changed. It forces rtnl_lock drop, but the process remains in the cycle until the message will be fully processed. So, there is no need to use this kludges now. Signed-off-by: Denis V.

* [IPSEC]: Move state lock into x->type->outputHerbert Xu2007-10-101-4/+4
| | | | | | | | | | | This patch releases the lock on the state before calling x->type->output. It also adds the lock to the spots where they're currently needed.

* [IPSEC]: Lock state when copying non-atomic fields to user-spaceHerbert Xu2007-10-101-6/+8
| | | | | | | | | | | | | | | | | | | This patch adds locking so that when we're copying non-atomic fields such as life-time or coaddr to user-space we don't get a partial result. For af_key I've changed every instance of pfkey_xfrm_state2msg apart from expiration notification to include the keys and life-times. This is in-line with XFRM behaviour. The actual cases affected are: * pfkey_getspi: No change as we don't have any keys to copy. * key_notify_sa: + ADD/UPD: This wouldn't work otherwise. + DEL: It can't hurt.

* [XFRM] user: Move attribute copying code into copy_to_user_state_extraHerbert Xu2007-10-101-29/+47
| | | | | | | | | | | | | | | | | | | | | | | Here's a good example of code duplication leading to code rot. The notification patch did its own netlink message creation for xfrm states. It duplicated code that was already in dump_one_state. Guess what, the next time (and the time after) when someone updated dump_one_state the notification path got zilch. This patch moves that code from dump_one_state to copy_to_user_state_extra and uses it in xfrm_notify_sa too. Unfortunately whoever updates this still needs to update xfrm_sa_len since the notification path wants to know the exact size for allocation. At least I've added a comment saying so and if someone still forgest, we'll have a WARN_ON telling us so. I also changed the security size calculation to use xfrm_user_sec_ctx since that's what we actually put into the skb. However it makes no practical difference since it has the same size as xfrm_sec_ctx. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Move common code into xfrm_alloc_spiHerbert Xu2007-10-102-15/+24
| | | | | | | | | | | | | | | | | 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>
* [IPSEC]: Remove gratuitous km wake-up events on ACQUIREHerbert Xu2007-10-101-2/+0
| | | | | | | | | | | There is no point in waking people up when creating/updating larval states because they'll just go back to sleep again as larval states by definition cannot be found by xfrm_state_find.

* [IPSEC]: Store IPv6 nh pointer in mac_header on outputHerbert Xu2007-10-101-2/+0
| | | | | | | | | | | | | | | | | | | | Current the x->mode->output functions store the IPv6 nh pointer in the skb network header. This is inconvenient because the network header then has to be fixed up before the packet can leave the IPsec stack. The mac header field is unused on output so we can use that to store this instead. This patch does that and removes the network header fix-up in xfrm_output. It also uses ipv6_hdr where appropriate in the x->type->output functions. There is also a minor clean-up in esp4 to make it use the same code as esp6 to help any subsequent effort to merge the two. Lastly it kills two redundant skb_set_* statements in BEET that were simply copied over from transport mode. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | Constructs of the form xfrm_state_hold(x); foo(x); xfrm_state_put(x); tend to be broken because foo is either synchronous where this is totally unnecessary or if foo is asynchronous then the reference count is in the wrong spot. In the case of xfrm_secpath_reject, the function is synchronous and therefore we should just kill the reference count. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | Most of the code in xfrm4_output_one and xfrm6_output_one are identical so this patch moves them into a common xfrm_output function which will live in net/xfrm. In fact this would seem to fix a bug as on IPv4 we never reset the network header after a transform which may upset netfilter later on.

* [NET]: Support multiple network namespaces with netlinkEric W. Biederman2007-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | | Each netlink socket will live in exactly one network namespace, this includes the controlling kernel sockets. This patch updates all of the existing netlink protocols to only support the initial network namespace. Request by clients in other namespaces will get -ECONREFUSED. As they would if the kernel did not have the support for that netlink protocol compiled in. As each netlink protocol is updated to be multiple network namespace safe it can register multiple kernel sockets to acquire a presence in the rest of the network namespaces. The implementation in af_netlink is a simple filter implementation at hash table insertion and hash table look up time. Signed-off-by: Eric W.

If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing.
