* cache: move lifetime feature to main cache codePablo Neira Ayuso2009-01-251-3/+1
| | | | | | | | The lifetime feature is used by all working modes, it is useful to know how long it has been an entry living in the cache. This patch moves the lifetime feature to the main caching code. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: remove register_fds hooksPablo Neira Ayuso2009-01-171-1/+0
| | | | | | | This patch moves the file descriptor registration after the initialization instead of having a specific hook for this. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: rename overrun handler to resync handlerPablo Neira Ayuso2009-01-171-6/+6
| | | | | | | | | This patch is a cleanup. The overrun handler is actually a way to resynchronize against the conntrack kernel table. The name overrun was used because it was initially its purpose. The new naming shows its genericity. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: rework of the hash-cache infrastructurePablo Neira Ayuso2009-01-151-26/+29
| | | | | | | | | | | | | | | | | | | | | | | | Currently, the caching system is implemented in a two layer architecture: hashtable (inner layer) and cache (upper layer). This patch reworks the hash-cache infrastructure to solve some initial design problems to make it more flexible, the main strong points of this patch are: * Memory handling is done in the cache layer, not in the inner hashtable layer. This removes one of the main dependencies between the hashtable and the cache classes. * Remove excessive encapsulation: the former cache used to hide a lot of details of the inner hashtable implementation. * Fix over-hashing of some operations: lookup-delete-add required three hash calculations. Similarly, the update-or-add operation required two hash calculations. Now, we calculate the hash once and re-use the value how many times as we need. This patch simplifies the caching system. As a result, we save ~130 lines of code. Small code means and less complexity means less chance to have bugs. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: add cache statistics via `-s cache'Pablo Neira Ayuso2008-12-211-0/+3
| | | | | | | | | | | | This patch adds cache statistics that you can check via `conntrackd -s cache'. This information is useful for trouble-shooting. This patch replaces several log messages that can be triggered in runtime. The idea behind this patch is to avoid log message flooding under errors.

* src: move callbacks to run.c for better readabilityPablo Neira Ayuso2008-11-271-1/+1
| | | | | | | | | This patch is a cleanup. It moves the callbacks from netlink.c to run.c where they are actually invoked. This is better for code readability as I usually have to switch from run.c to netlink.c to remember what the callbacks actually do. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* filter: do not filter in user-space if kernel supports BSFPablo Neira Ayuso2008-10-211-1/+1
| | | | | | | | | This patch avoids a double filtering in user-space and kernel-space if the kernel support BSF. Since we do not use BSF for dumps and resyncs, we add a new parameter to ignore_conntrack to indicate if we have to perform the filtering in user-space or not.
