| | | | | | | | - split expect_api_test.c into small example files expect_*.c - introduce alias tags for original tuple attributes - introduce nfexp_sizeof and nfexp_maxsize - build expectation attributes iif they are set - fix l3num setting in expect/build.c

* - fix compilation warning in snprintf.c/C=EU/ST=EU/CN=Pablo Neira Ayuso/emailAddress=pablo@netfilter.org2007-04-242-1/+10
| | | | | | - introduce the new compare infrastructure: much simple than previous - introduce nfct_maxsize for nf_conntrack object allocated in the stack - more strict checkings in nfct_set_attr: third parameter is const
* add extern C's to public headers (Phil Dibowitz)/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2007-03-298-0/+64

* [PATCH] Fix icmp_id setter and doc (Phil Dibowitz <phil@ipom.com>)/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=kaber/emailAddress=kaber@netfilter.org2007-03-171-1/+1
| | | | | | | | ICMP ID is stored as a u_int16_t, but its setter function derefs it's arguement as a u_int8_t. Additionally the api "doc" claims it's a u8, when it's not. This patch fixes both.
* [patch] libnetlink_conntrack compile fix (Thomas Jarosch ↵/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=kaber/emailAddress=kaber@netfilter.org2007-03-161-0/+4

| | | | | - introduce NFCT_O_PLAIN flag: NFCT_O_DEFAULT points to NFCT_O_PLAIN - remove commented line in nfct_new()

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

* Introduce various API changes throughout the library stack/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=laforge/emailAddress=laforge@netfilter.org2006-01-142-2/+5
| | | | | | | | | | | 1) make libnfnetlink dynamically allocate it's handles 2) apply that change throughout libnetfilter_* 3) add {nfq,nflog,nfct}_open_nfnl() functions that open the specific subsystem on top of an existing nfnl_handle, which is required for upcoming libnetfilter_conntrack_helper The changes break ABI and API compatibility of libnfnetlink, but don't break ABI or API compatibility of the libnetfilter_* libraries.

* o add IPv6 support/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2005-12-265-5/+92
| | | | | | | | | | | | o clean up layer-4 compare functions o finish the comparison infrastructure: support for tuple/mark matching o fix bug in the default event display when used in conjunction with the comparison infrastructure. o Bumped version to 0.0.30 Thanks to Yasuyuki Kozakai for: [LIBNETFILTER_CONNTRACK] fix dumping IPv6 connections that in included in this commit.
* Yasuyuki confirmed that l3protonum must be u_int8_t instead of u_int16t.svn_t_libnetfilter_conntrack-0.0.29/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2005-12-211-10/+8
| | | | | Another reason to use such type: the nfnetlink header uses u_int8_t to set the layer 3 protocol family, so let's keep some consistency.
* Add support for per-family table flushing. ie. flush just AF_INET entries. ↵/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2005-12-191-2/+2

| | | | | | | | | o Added the comparison infrastructure for layer-4 protocols o Added libnetfilter_conntrack_[tcp|udp|icmp|sctp].h that contains the protocol flags used by the comparison infrastructure o Added nfct_conntrack_compare to compare two conntracks based on flags o Killed nfct_event_netlink_handler o nfct_event_[conntrack|expect] requires ROOT privileges (reason: netlink multicast) o Bumped version to 0.29

| | | | | | | update_conntrack, and it doesn't even fit well for both cases. So I decided to kill it and inline the code adapting it when was necessary. o Convert all unsigned int/long to POSIX types u_int32_t. Better now than later :(.
* o move nfct_handler to libnetfilter_conntrack.c, better for encapsulation/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2005-11-061-4/+0
| | | | | | | | o fixed ICMP ID handling o fix -> libtool: link: libtool library `nfct_proto_*.la' must begin with `lib' o remove wrong flag at extensions/Makefile.am o bumped version to 0.0.26 o fixed versioning :(

| | | | | | | | | | | | o nfct_build_conntrack flit bits of status, timeout, id and mark. o finish incomplete support for marks: kernel part missing (patch on the way) o network byte order translation in build_conntrack instead of nfct_conntrack_alloc. Now this translation is transparent to the clients of the library. o Kill last blank space output in nfct_sprintf_[conntrack|expect] (Thanks to Krzysztof Oledzk for reporting this). o add missing initialization of buffer in nfct_default_*_display. o Bumped version to 0.2.5.

| | | | | | | | | | | | | Munich, Germany for providing the "fast" hardware to reproduce spurious bugs ;) List of changes: o Replace misleading flag NFCT_ANY_GROUP by NFCT_ALL_GROUPS o Update test file to use NFCT_ALL_GROUPS o Add missing check of CTA_PROTOINFO_TCP that resulted in a segfault in conjuction with events. o Fix ICMP conntracks output o Add missing prototype definition of nfct_default_expect_display_id in libnetfilter_conntrack.h
* o Added the expectation printing API/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=pablo/emailAddress=pablo@netfilter.org2005-10-301-4/+10

| | | | | | | | o move build_tuple_proto and build_protoinfo to the extensions where it really belongs to. o Reworked the conntrack and expect netlink handlers o Fix expectation table output, now it's similar to the /proc output o Bumped version to 0.2.1

| | | | | | | | | | o libnetfilter_conntrack.h splitted into two parts: what is visible to application programs and what is visible to extensions. o Killed includes asm/types.h and linux/if.h o Fixed nasty wrong ipv6 definition o Stolen the status bits from ip_conntrack.h, we don't include ip_conntrack.h anymore. o move nfct_handle to libnetfilter_conntrack.c: better for encapsulation

| | | | | | | | | | | | | | | o Added some very brief comments to libnetfilter_conntrack.h o Implemented the conntrack printers API nfct_sprintf_* o Now nfct_default_conntrack_display display the classical /proc output, and nfct_default_conntrack_display the classical + conntrack ids o Use nfnl_talk if there's no data expected from kernel space to be processed, that is the case of nfct_[get|delete]_conntrack o Added some missing memset's zeroing o Code simplification: killed some char *buf where struct nfnlhdr is enough o Killed protocol handler destructors (fini) and nfct_unregister_proto: The library is unloaded if something goes wrong (different library versions), the modules never gets inserted in the proto_list. Fixes a segfault. o Bumped version to 0.2.0

| | | | | | | | | | | | | | include/Makefile.am. - Rename list_conntrack_handler to callback_handler, IMHO a proper name for such function. - Use new nfnl_open prototype: Now it's got four parameters. - Kill recurrent definition of the structure nfnlhdr: Actually this should go somewhere in libnfnetlink, later. - Ignore utils subdirectory. It contains a testsuite that is currently broken. Yes I know you're aware of it ;) it's on the TODO list. I'll fix later. - ctnl_error now has a nicer definition. - kill some unneeded ctnl_error messages on failure. (Pablo Neira)
