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
Dumping objects as environment variables has never been implemented
completely and only increases the size of the library for no real
purpose. Integration into scripts is better achieved by implementing
a python module anyway.
The idea of a common handle is long revised and only misleading,
nl_handle really represents a socket with some additional
action handlers assigned to it.
Alias for nl_handle is kept for backwards compatibility.
Replaces obsolete calls to nla_get_addr() and nla_get_data()
with nl_addr_alloc_attr() respectively nl_data_alloc_attr().
Also fixes missing error handling while parsing routing multipath
configuration.
In order for the interface to become more thread safe, the error
handling was revised to no longer depend on a static errno and
error string buffer.
This patch converts all error paths to return a libnl specific
error code which can be translated to a error message using
nl_geterror(int error). The functions nl_error() and
nl_get_errno() are therefore obsolete.
This change required various sets of function prototypes to be
changed in order to return an error code, the most prominent
are:
struct nl_cache *foo_alloc_cache(...);
changed to:
int foo_alloc_cache(..., struct nl_cache **);
struct nl_msg *foo_build_request(...);
changed to:
int foo_build_request(..., struct nl_msg **);
struct foo *foo_parse(...);
changed to:
int foo_parse(..., struct foo **);
This pretty much only leaves trivial allocation functions to
still return a pointer object which can still return NULL to
signal out of memory.
This change is a serious API and ABI breaker, sorry!
Adds all missing routing attributes and brings the routing
related code to a working state. In the process the API
was broken several times with the justification that nobody
is using this code yet.
The changes include new example code which is also a prototype
for how plain CLI tools could look like to control routes.
This interface was internal so far which required all code defining
caches to be compiled with the sources available.
In order to simplify the interface, the co_msg_parser prototype was
changed to take the struct nl_parser_param directly instead of a
void *. It used to be void * because the co_msg_parser was directly
passed as the NL_CB_VALID callback function.
