Tobias Brunner 8ec51f83e5 Don't create roam jobs based on cached/cloned routes. 2012-06-15 16:44:18 +02:00
Tobias Brunner 9896b6bd58 Don't compare ports when comparing cached routes. 
At least src_ip has a port set sometimes.

Tobias Brunner 686cfd4e34 Added support for untruncated MD5 and SHA1 HMACs in ESP as used in RFC 4595.

Mirko Parthey 7b21873668 Fix network interface deletion handling in kernel-netlink plugin. 
When the kernel reports the deletion of an interface (RTM_DELLINK),
the cached interface attributes, including ifindex, become invalid
and must be forgotten.

Interface link state changes ("up" and "down") show up as RTM_NEWLINK,
so they will not cause a cached entry to be removed or
prevent listening to address change notifications.

Once an interface has been deleted, the kernel ought to stop sending
notifications for it. If the interface gets recreated with the same
name later, the kernel again reports RTM_NEWLINK, which causes a new
cache entry to be created.

There should be no reason to keep a stale cache entry around, as was
claimed in the comment.

Tobias Brunner 051226d5c0 Silently install route again, even if it did not change. 
Address/interface changes can cause the route to disappear. Afterwards
the route might look the same but that does not mean it is still installed.

Tobias Brunner 2e370a300d Allow routing table IDs > 255 when filtering them. 2011-07-29 12:16:18 +02:00
Tobias Brunner d7a59f1976 Install fallback drop policies to avoid transmitting unencrypted packets. 
During the update of a CHILD_SA (e.g. caused by MOBIKE) the old policy
is first uninstalled and then the new one is installed.  In the short
time in between, where no policy is available in the kernel, unencrypted
packets could have been transmitted.
 2011-07-27 13:44:33 +02:00
Tobias Brunner fbedc6a45b Remove policies in kernel interfaces based on their priority. 
This allows to unroute a connection while the same connection is
currently established.  In this case both CHILD_SAs share the same
reqid but the installed policies have different priorities.

Tobias Brunner 9f49464d56 Reduce memory usage of policy history caching. 
Only cache data as needed (e.g. traffic selectors only for forward
policies) and at most once for each IPsec SA.

Tobias Brunner c225f9b558 Keep the mutex locked as long as possible when deleting policies. 
This change tries to prevent a race condition where a thread tries to
install the same policy another thread is currently deleting. If the
second thread releases the mutex in del_policy too early the first
thread could assume the policy does not exist (as it is not cached
anymore) but would not be able to actually install it if the second
thread was not yet able to delete it.

Tobias Brunner bd4f7dab75 Properly unlock the policy if no change in the kernel is required. 2011-07-06 09:43:46 +02:00

Tobias Brunner e26304348c Replaced simple iterator usages. 2011-07-06 09:43:45 +02:00
Tobias Brunner f0ba8ae042 Record the history of a policy installed in the kernel. 
This allows to properly delete a policy e.g. if reauth=yes and
auto=route, because reqids are increased during reauthentication.

It also avoids overriding an installed policy with a trap policy.

Tobias Brunner f526b35c45 Properly copy interface name if unknown. 
We use a static string if the interface name is unknown, so using memcpy
with IFNAMSIZ is incorrect as that would overrun the static string.
