2010-10-13Don't include pktloc_syntax.h in BUILT_SOURCESThomas Graf1-1/+0
2010-10-13route_obj: don't add empty destination to nlmsgDavid Lamparter1-1/+2
don't try to give the kernel an empty RTA_DST attribute. this would previously happening on trying to delete the default route as returned from the kernel. the kernel doesn't add a RTA_DST atttribute, so libnl does nl_addr_alloc(0) and inserts a zero-length RTA_DST attribute into the deletion request, which the kernel then refuses with ERANGE.

2010-10-13automake: add ${top_builddir}/include to AM_CFLAGSAndreas Bießmann1-1/+1
This patch enables out-of-source builds like this $ cd builddir && src_dir/configure && make Before this patch there was an error about missing netlink/version.h which is built by automake in top_builddir rather than top_srcdir which is already in include search path.

2010-10-13Put preprocessor definitions in AM_CPPFLAGSMatthew L. Creech1-1/+1
When an alternate kernel header include directory is added in CPPFLAGS, the libnl build fails. This is because the local copy of kernel headers is added in AM_CFLAGS, which gets included after CPPFLAGS in the automake-generated makefile. Switching to AM_CPPFLAGS fixes the problems.
2010-10-13add user data to change_func_t for cachesAndreas Fett2-11/+13
the patch below adds the possibility to pass user data to callbacks of type change_func_t when using the nl_cache_mngr_* family of functions. If there is any better way to do this, without duplicating the code in cache_mngr.c please let me know.
2010-10-13Trivial fix for TBF memleakDenys Fedorysychenko1-0/+6
Without this patch, running alloc / free cache loop will lead to huge memory leaks on machine with 3000 interfaces with tbf qdiscs.

2010-04-19Fix rule attribute comparisonPatrick McHardy1-0/+2
Rules don't have unique identifiers, so all attributes are compared by initializing the ID mask to ~0. This doesn't work however since nl_object_identical verifies whether the ID attributes are actually present before comparing the objects, which is never the case. Work around by using the intersection of present attributes when comparing two rule objects. Signed-off-by: Patrick McHardy <kaber@trash.net>

2010-04-19cache: properly invoke change_cb for deleted objects in nl_cache_resync()Patrick McHardy1-2/+8

2010-03-10Fix a bug when calculating ticks_per_usecJose Ignacio Naranjo Hernández1-19/+16
I've noticed a wrong behavior when setting up some delays in a netem qdisc. I will try to make the things easier for the reader describing the calls path. To set up a delay (or jitter...) I use 'rtnl_netem_set_delay' which requires an int parameter that tells the delay in micro seconds. Inside this func, the delay is set up with the help of 'nl_us2ticks', which is just an arithmetic operation (us * ticks_per_usec), where us is the input parameter and ticks_per_usec is a global variable initialized in 'get_psched_settings'. And here is the problem: If this variable is going to be calculated using '/proc/net/psched', I think the file scan is not done properly. I don't understand what the meaning of the asterisk is here: int r = fscanf(fd, "%08x%08x%08x%*08x", &tick, &us, &nom); if (4 == r && nom == 1000000 && !got_tick) ticks_per_usec = (double)tick/(double)us; The execution path never gets in the if statement, because r is always 3, and if the fourth parameter is read (avoiding the asterisk), there is no variable to store it in, so it comes a segv. In my opinion we can get rid of the if statement, because I think the proc psched file has always a fixed format of 4 parameters, and 'nom' is always 1000000 (http://lxr.linux.no/#linux+v2.6.32/net/sched/sch_api.c#L1678). Find attached a patch I did, if I am correct.

Create new function nl_send_iovec() to be used to send multiple 'struct iovec' through the netlink socket. This will be used for NF_QUEUE, to send packet payload of a modified packet. Refactor nl_send() to use nl_send_iovec() sending a single struct iovec. Create new function nl_auto_complete() by refactoring nl_send_auto_complete(), so other functions that call nl_send may also use nl_auto_complete() Signed-off-by: Karl Hiramoto <karl@hiramoto.org>

addr_obj.ops.oo_id_attrs included ADDR_ATTR_PEER, so any address that didn't have a peer address set would compare as unequal to itself, meaning it could never be removed from a cache after it was added, etc.
2009-09-02Patch for unexpectedly aligned messagesMarc de Kruijf1-1/+1
I found the following bug, where nlmsg_ok() in lib/msg.c would incorrectly return 'true' when the input argument 'remaining' was a negative number. This happens when the message is not aligned the way that libnl expects (although it is still legal). In the comparison of the signed and unsigned numbers on line 284, the signed number gets converted to an unsigned number, which is unexpected and naturally produces a bug. My patch is below. The cast is ugly, but it fixes the problem.

2008-10-10Only include local addr as peer addr if providedWolfgang Steudel1-1/+1
we're using libnl-1.1 for a project. When trying to delete all addresses of an interface by only setting interface index and address family of an rtnl_addr and executing rtnl_addr_delete() we received some error (I don't remember what it was). The bug(?) is in build_addr_msg() in lib/route/addr.c: IFA_ADDRESS is set to a_local when a_peer is not set, without checking if a_local was set. We just added if (tmpl->ce_mask & ADDR_ATTR_LOCAL) after the "else" (line 496 in the current git).
