It has been a request that multiple libnl versions should be installabe
in parallel.
In order to achieve this, the basename of the library was changed to
libnl-3 which reflects the 3rd generation of libnl APIs. It also means
that release based library versioning is left behind and libtool
versioning is used instead.
Projects using pkgconfig will automatically link against the new library
basename and will not notice a difference.
The SO versioning is based on the glib model:
current := 100 * minor + micro - revision
revision := revision
age := age (number of backwards compatible versions)
As Jan Engelhardt pointed out, pktloc.c is currently licenses under the GPL
rather than the LGPL. This is a result of its previous existance in src/
which is GPL licensed. I missed to change its license when moving it to
lib/. Since I am the only contributor to the code, I am changing the license
hereby.
This patch fixes an unaligned access for IPv6. On systems with strict alignment requirements, the unaligned access will either result in garbage data or a crash.
Now the return value in case group id is not find is 0. Change it to
return -NLE_OBJ_NOTFOUND which makes more sense. This should not break
anything because genl_ctrl_grp_by_name is static and called only from
genl_ctrl_resolve_grp. genl_ctrl_resolve_grp already might return
-NLE_OBJ_NOTFOUND.

I've found a bug in the following scenario (fragment of code):
while (1) {
struct nl_sock *sk = nl_socket_alloc();
if (sk == NULL) {
fprintf(stderr, "Failed to allocate nl socket\n");
break;
}
nl_socket_set_local_port(sk, 0);
nl_socket_free(sk);
}
The problem is that nl_socket_set_local_port(, 0) does not
release local port if it is allocated before.
This patch has been in Fedora and RHEL for a while. It adds a mutex
to protect the port map from concurrent thread accesses.
Original patch from Stefan Berger <stefanb@us.ibm.com>.
Modified to use configure.in to check for libpthread
stores rtnl_link object in address if cache is availble. Provide access
via rtnl_addr_get_link() and rtnl_addr_set_link().
Add rtnl_addr_get() which searches a address cache for an address
matching ifindex and local address.
OK i found the bug, is is the patch !!
Can someone push it into the git tree ?

=========================
My analysis:
I guess that the pay load is *struct fib_rule_hdr*
struct fib_rule_hdr {
__u8 family;
__u8 dst_len;
__u8 src_len;
__u8 tos;
__u8 table;
__u8 res1; /* reserved */
__u8 res2; /* reserved */
__u8 action;
__u32 flags;
};
> [PAYLOAD] 12 octets
> 02 00 00 00 0a 00 00 01 00 00 00 00 ............
so
family = 02 , fine
table = 10, fine
but
src_len =0 !!!! should be 32
Adds rtnl_tc_get_link() returning the link associated with a tc
object.
Don't clone link associated with tc object when cloning the tc
object, refer to same link instead and bump refcnt.
Fix refcnt leak when assigning link in msg parser.
- avoid unncessary name change requests
The kernel does not check if the specified IFNAME is different
from the current name. It assumes that if IFNAME and ifindex
are both specified, a name change is requested. Therefore avoid
specyfing IFNAME if ifindex is provided and original and new
name are identical.
- move link building to own function (to allow link add later on)
- error if immutable changes have been made
- better documentation
Provide nl_pickup() to pick up an answer from a netlink request and parse
it using the supplied parser.
Add rtnl_link_get_kernel() which sends an RTM_GETLINK to the kernel to
fetch a single link directly from the kernel. This can be faster than
dumping the whole table, especially if lots of links are configured.
