* src: remove obsolete debug() and debug_ct() callsPablo Neira Ayuso2009-02-201-2/+0
| | | | | | | This patch removes debug() and debug_ct(), I haven't use the debugging information that these functions provide in years. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* src: rework of the hash-cache infrastructurePablo Neira Ayuso2009-01-151-18/+18
| | | | | | | | | | | | | | | | | | | | | | | | 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>

* revert relicensing... still we use linux_list.h code which seems to be GPLv2 ↵/C=EU/ST=EU/CN=Pablo Neira Ayuso/emailAddress=pablo@netfilter.org2008-03-081-1/+1

* - conntrack-tools requires libnetfilter_conntrack >= 0.0.81 /C=EU/ST=EU/CN=Pablo Neira Ayuso/emailAddress=pablo@netfilter.org2007-07-091-1/+1
| | | | | | | | | | | | | - add len field to nethdr - implement buffered send/recv to batch messages - stop using netlink format for network messages: use similar TLV-based format - reduce synchronization messages size up to 60% - introduce periodic alive messages for sync-nack protocol - timeslice alarm implementation: remove alarm pthread, remove locking - simplify debugging functions: use nfct_snprintf instead - remove major use of libnfnetlink functions: use libnetfilter_conntrack API - deprecate conntrackd -F, use conntrack -F instead - major rework of the network infrastructure: much simple, less messy
* first step forward to merge conntrackd and conntrack into the same building ↵/C=EU/ST=EU/CN=Pablo Neira Ayuso/emailAddress=pablo@netfilter.org2007-04-161-0/+72
