2011-03-05src: use limits.h headerJan Engelhardt
values.h is not present on other systems, and the glibc copy reads right away: Old compatibility names for <limits.h> and <float.h> constants. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2011-02-08doxygen: exclude EXPORT_SYMBOL and skip .git filesPablo Neira Ayuso
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2011-02-03doc: don't show up EXPORT_SYMBOL in doxygenPablo Neira Ayuso
Patrick reports that the doxygen output shows up EXPORT_SYMBOL and tells how to fix this: > I just noticed the EXPORT_SYMBOLs in libmnl showing up in > the doxygen output. Just in case you want to avoid this, > what I'm doing in libdect is (besides the appopriate linker > flags): > > #define __visible __attribute__((visibility("default"))) > > #define EXPORT_SYMBOL(x) typeof(x) (x) __visible > > > This allows to use EXPORT_SYMBOL as in the kernel, IOW > after the function definition. This patch also removes -Wredundant-decls to avoid a warning in every single use of this new approach. Now, this looks more like the Linux kernel way of exporting symbols.

2011-01-08examples/genl: support dumping the genl familiesJan Engelhardt

2010-12-31build: use only AC_CANONICAL_HOSTJan Engelhardt
Calculating AC_CANONICAL_TARGET is superfluous, because libmnl is not a code generator. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-12-31build: use AM_CPPFLAGSJan Engelhardt
Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

2010-12-22headers: add local copy of linux/netlink.h to libmnlPablo Neira Ayuso
Davem suggested to add a copy of linux/netlink.h to avoid compilation problems in all cases scenarios. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-12-20include: add missing unistd.hJan Engelhardt
When a project uses MNL_SOCKET_BUFFER_SIZE without having included unistd.h, it gets: mystuff.c:36:2: warning: implicit declaration of function "getpagesize" It is libmnl's job to include this, since mystuff.c did not use getpagesize anywhere. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-12-17doc: add new website at netfilter.org to doxygenPablo Neira Ayuso

2010-12-17nlmsg: add new message batching infrastructurePablo Neira Ayuso
This patch adds the new message batching infrastructure that allows to store several messages into one single datagram. This patch includes an example for ctnetlink. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-12-17header: use getpagesize() for MNL_SOCKET_BUFFER_SIZEPablo Neira Ayuso
This system call returns PAGE_SIZE which depends on the architecture. See linux/netlink.h for more information on the appropriate datagram size for netlink. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-12-17attr: add put function that allows to check buffer sizePablo Neira Ayuso
This patch adds a set of function that allows to check the size of the buffer. This is useful for attribute batching. This is strongly based on a patch from Jozsef. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-12-12callback: use of inline in mnl_cb_run*() functionPablo Neira Ayuso
This patch defines a new function __mnl_cb_run() which is inlined in mnl_cb_run() and mnl_cb_run2(). This patch increases the size of the library in ~1KB. IIRC, Davem suggested this during the Netfilter Workshop. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-12-09header: add MNL_ARRAY_SIZE(x)Pablo Neira Ayuso
This patch adds MNL_ARRAY_SIZE(x) which likely to defined over and over again if you use mnl_cb_run2(...). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-11-22attr: add mnl_attr_nest_cancel()Pablo Neira Ayuso
This patch adds mnl_attr_nest_cancel() that allows to cancel the current nest that we are building. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-11-19nlmsg: remove unused function mnl_nlmsg_aligned_size()Jan Engelhardt
With the new CFLAGS, a notification pops up: nlmsg.c:64:8: warning: no previous prototype for "mnl_nlmsg_aligned_size" Marking it thus as static reveals it can be removed. nlmsg.c:64:15: warning: "mnl_nlmsg_aligned_size" defined but not used Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-11-19build: tag function headers rather than decls as exportedJan Engelhardt
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-11-19nlmsg: remove unexisting mnl_nlmsg_total_sizePablo Neira Ayuso
Remove function whose implementation does not exist. It seems to me like a leftover from the early days of the library. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-11-19license: change licensing terms from GPLv2+ to LGPLv2.1+Pablo Neira Ayuso

2010-11-16socket: propagate sendto/recvmsg's return typesJan Engelhardt
sendto/recvfrom return ssize_t, so libmnl should not truncate the result range. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-11-16attr: avoid multiple definition of hidden variableJan Engelhardt
When nesting two mnl_attr_for_each loops, the __len__ variable will be declared twice, eliciting a warning when -Wshadow is turned on. There can also be warnings in pre-C99 because declarations and code are mixed. Do without any temporaries that are not explicitly specified as macro parameters.

2010-11-15src: implement both GCC visibility support and export scriptCristian Rodríguez
Read "How to write shared libraries" from Ulrich Drepper for more information on this patch. Specifically section 2.2: Export control and section 3: Maintaining APIs and ABIs. Signed-off-by: Cristian Rodríguez <cristian.rodriguez@opensuse.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2010-11-11attr: remove redundant check for NULLJan Engelhardt
Calling mnl_attr_parse with cb==NULL is pointless, because the function will do nothing else. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-11-07nlmsg: rework mnl_nlmsg_fprintfPablo Neira Ayuso
This patch reworks mnl_nlmsg_fprintf. It breaks backward compatibility of this function, there was no way to improve it without doing so (and we are still in time to break thing, BTW). Signed-off-bu: Pablo Neira Ayuso <pablo@netfilter.org>

2010-10-30examples: remove redundant castsJan Engelhardt
2010-10-25attr: rename str_null from NULL awayJan Engelhardt
A small little pedantism: NULL (as in, the pointer) isn't NUL (as in, the character with value zero, '\0'). I propose to rename it to strz, for the zero-terminated string (sometimes referred to as ASCIZ string, but of course C isn't tied to ASCII).

2010-10-22socket: use more appropriate types for mnl_socket_bindJan Engelhardt
groups, being a bitmask, should be unsigned; and let's also use pid_t for pid. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-22callback: mnl_cb_run should use a void *Jan Engelhardt
Because in most cases, it won't be a nul-terminated string :) Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2010-10-22attr: string functions should take char *Jan Engelhardt
I do not quite see the point of using strlen in conjunction with non-string data; so let's use char * as argument types to catch misuses. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
