| | | | | | | | | | | | | | Commit 3cb28534d34392ceec4adead0cfa97039796ccb7 enables building of cli always as part of `make check`.

* lib: escape usage of strerror_l() if it doesn't exist in libcAlexey Brodkin2017-03-121-0/+6
| | | | | | | | | | | | | | | | uClibc doesn't implement strerror_l() and thus libnl starting from 3.2.29 couldn't be compiled with it any longer. To work-around that problem we'll just do a check on strerror_l() availability during configuration and if it's not there just fall back to locale-less strerror().

* include: don't include kernel headers in public libnl3 headersThomas Haller2017-03-0242-2/+86
| | | | | | | | | | | | | | | | | It would be desirable not to include kernel headers in our public libnl3 headers. As a test, remove all those includes, and fix compilation by explicitly including the kernel headers where needed. In some cases, that requires forward declaration for kernel structures, as we use them as part of our own headers. Realistically, we cannot drop those includes as it probalby breaks compilation for users that expect to get a certain kernel header when including a libnl3 header. So, this will not be done and the includes will be restored in the next commit. Do this step to show how it would be and to verify that we could build with such a change. The reason not to do this is backward compatibility (at compile-time).

* nl-link-stats: prefer RTNL_LINK_STATS_MAX over __RTNL_LINK_STATS_MAXThomas Haller2016-11-291-2/+2
| | | | | | | | The result is basically the same, but I feel that __RTNL_LINK_STATS_MAX is an internal variable that shouldn't be used. Thus, let's iterate instead until <= MAX. Signed-off-by: Thomas Haller <thaller@redhat.com>
* src: nl-link-stats: use correct rtnl link stats maximumTobias Klauser2016-11-291-2/+2
| | | | | | | | | Use __RTNL_LINK_STATS_MAX instead of RTNL_LINK_STATS_MAX when iterating over all rtnl link stat counters. Otherwise, the last stat counter will always be missing, as RTNL_LINK_STATS_MAX is the value of the last valid index. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
* src: switch to using strerror_l() instead of strerror_r()André Draszik2016-08-251-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | glibc provides two versions of strerror_r(), which can be chosen between using feature test macros _GNU_SOURCE and _POSIX_C_SOURCE. libnl is built using the former, hence we get the glibc special version, and all code so far has been written for this. Other C libraries like musl on the other hand only try to be posix compliant, and only ever provide the posix version of strerror_r(), which has a different signature. Uses in libnl hence generally cause printf() of an *int* with a *string format* specifier for that reason. Additionally, strerror_r() has been deprecated: http://austingroupbugs.net/view.php?id=655 Switch to using strerror_l().

* link/neigh: add flags option to link and neighbor cachesDavid Ahern2015-11-193-3/+33
| | | | | | | | | | | | | Both link and neighbor cache support specify multiple groups (nl_af_group), but the alloc_cache functions for both do not set the NL_CACHE_AF_ITER flag before populating the cache so only the first group is used by default.

* route: remove unnecessary include of private linux/if.hDavid Chappelle2015-03-171-0/+1
| | | | | | | | | | | | | | | | | | | Including linux/if.h in netlink/route/link.h causes issues in cases where libnl is used in conjuntion with other third party libraries that include net/if.h. Seems to be a long checkered history of symbol collisions between these two files. As it turns out, including linux/if.h from within netlink/route/link.h is actually unecessary. I resurrected a forgotten path from this thread: http://lists.infradead.org/pipermail/libnl/2012-April/000525.html By removing the include as the patch suggests we can get around the nuissance of the symbol collisions. https://github.com/thom311/libnl/pull/73 Signed-off-by: Thomas Haller <thaller@redhat.com>

* build: move copy of linux headers to private directoryThomas Haller2014-09-242-0/+2
| | | | | | | | | | | | | | | | | | | libnl3 contains a private copy of some kernel header files. Normally, users are expected to install libnl and specify -I$PREFIX/include/libnl3 as include path. As the private kernel header files are not installed, this works fine. However, it can be convenient to build against the libnl source directory, without installing libnl. In this case, the private kernel header files shaddow the system provided ones. This is undesired. Move these files to a different directory to avoid this clash. http://lists.infradead.org/pipermail/libnl/2014-September/001645.html Signed-off-by: Thomas Haller <thaller@redhat.com> Acked-by: Thomas Graf <tgraf@suug.ch>
