2012-05-31tests: conntrackd: add cthelper-test infrastructurePablo Neira Ayuso
This patch adds the automated testing infrastructure the user-space helpers. Basically, this adds the `cthelper-test' program that can be invoked from the command line: ./cthelper-test oracle-tns/oracle-tns-redirect.pcap tns tcp To test the helper with one PCAP file that contains traces of Oracle TNS traffic. This will also allow fuzzy testing of user-space helper, for further validation, not yet implemented. To compile this tool, you have to run: ./configure make check under the qa/cthelper-test/ directory. I'm doing like this because this directory is not included in the standalone tarball that make distcheck generates (I don't want to bloat it with development tools that can be retrieved from the git repository).

2012-05-31conntrackd: add cthelper infrastructure (+ example FTP helper)Pablo Neira Ayuso
This patch adds the user-space helper infrastructure. It also contains the implementation of the FTP helper in user-space. There's one example file that you can use to configure conntrackd as user-space connection tracking helper under: doc/helper/conntrackd.conf Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2012-05-28conntrackd: move ctnetlink code to ctnl.c (removed from run.c)Pablo Neira Ayuso
This patch moves the specific ctnetlink code to ctnl.c to prepare the introduction of the cthelper infrastructure. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-05-28conntrackd: generalize file descriptor infrastructurePablo Neira Ayuso
This patch generalizes the select-based file descriptor infrastructure by allowing you to register file descriptors and its callbacks. Instead of hardcoding the descriptors that needs to be checked. Now, struct fds_item contains a callback and pointer to data that is passed to it: struct fds_item { struct list_head head; int fd; + void (*cb)(void *data); + void *data; }; Then, we check which ones are active in the select_main_step() function: list_for_each_entry(cur, &STATE(fds)->list, head) { if (FD_ISSET(cur->fd, &readfds)) cur->cb(cur->data); } And it invoked the corresponding callback. I had to slightly modify the channel infrastructure to fit it into the changes. This modularity is required for the upcoming cthelper support. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-05-28conntrackd: simplify TCP connection handling logicPablo Neira Ayuso
Before this patch, we called accept() to likely return EAGAIN. This is not required as select() will tell us that we're ready to accept. Therefore, that early accept() invocation complicates the whole handling just to get the connection accepted a bit before. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

This patch uses the new infrastructure that allows us to filter by mark from kernel-space. This change ensures backward compatibility with kernels with no support for filtering by mark (Linux kernel <= 3.4.x). This requires lastest libnetfilter_conntrack library.
