* src: clarify licensing terms of library (GPLv2+)Pablo Neira Ayuso2011-12-301-3/+5
| | | | | | | | | | | | | | | | This patch is *not* changing the licensing terms of this library (which was initially released under GPLv2 and later on extended to GPLv2+ after contacting all the contributors who kindly agreed to extend it to any later GPL version). Jan says: "In libnetfilter_conntrack, there are many .c files declaring GNU GPL incorporated herein by reference without telling which version(s) exactly apply. Given src/main.c for example is actually GPL-2.0+, the reference made is ambiguous." This patch should definitely clarify this. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* conntrack: objopt: NO_EFFECTJiri Popelka2011-06-131-1/+1
| | | | | | | | | | | | static analysis (analysis based only on compiling of sources, not based on running of binary) of the code revealed the following problem: conntrack/objopt.c:63: self_assign: Assignment operation "ct->snat.l4max.all = ct->snat.l4max.all" has no effect.

* setobjopt: don't autocomplete the reply tuple for ICMP[v6]Pablo Neira Ayuso2009-12-211-2/+15
| | | | | | | | This patch fixes the autocomplete feature for ICMP[v6] entries that makes the kernel return EINVAL. Basically, we skip the autocomplete since this is already done in the setter. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* src: set specific array size for the APIPablo Neira Ayuso2008-11-231-2/+2
| | | | | | | This patch adds the size of the arrays to set to NULL unset elements. This helps to spot unset functions for new attributes. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* API: use of __builtin_expect in error checking pathsPablo Neira Ayuso2008-10-301-2/+2
| | | | | | | | | This patch introduces likely() and unlikely() that use __builtin_expect to assist the compiler in the branch decisions. I am assuming that we have no clients of libnetfilter_conntrack that use gcc < 2.96. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* objopt: use indirect calls instead of switchPablo Neira Ayuso2008-10-301-63/+99
| | | | | | This patch replaces the use of switch by indirect function calls. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* cleanup: split internal.h into several internal header filesPablo Neira Ayuso2008-07-251-1/+1
| | | | | | | This patch cleanups the internal headers by splitting them into several logical pieces. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | status flags bits of conntrack objects in userspace can be set and unset as it happens with other attributes. - nfct_get_objopt with NAT detectors previously checks if the status attribute is set, otherwise it just skips it.

- object oriented infrastructure - extensible and configurable output (XML) - low level functions to interact with netlink details - fairly documented Still backward compatible.
