5702d4c1b9 Only include local addr as peer addr if provided
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).

ef50a38fbd Fix memory leaks when sending of message failed

1155370f52 Rename struct nl_handle to struct nl_sock
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.

b4fbe1d34d Replace RTNL_LINK_NOT_FOUND with just 0
The interface index 0 is reserved and can be safely used to
signal that the device does not exist.

eed2afaab7 Remove obsolete nla_get_addr() and nla_get_data()
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.

8a3efffa5b Thread-safe error handling
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!

107dc162c5 patch: fixed up support for tables in rules 2008-05-08 17:56:11 +02:00

cc9c6d6384 Added two new functions to facilitate processing the nexthop entries for routes.
Added rtnl_route_foreach_nexthop() to walk the list of nexthops invoking a
caller-provided callback for each nexthop entry, and added rtnl_route_nexthop_n()
to retrieve the Nth nexthop entry in the list.

48e1e5c472 Speed up metrics comparison
Using rtnl_route_get_metric() for route comparison became a bottleneck
because each metric which was not available resulted in the generation
of an error message. This changeset avoids this by accessing rt_metrics
and rt_metrics_mask directly while comparing route objects.

85808860b6 Route cache support
This changesets adds the possibility to fill a nl_cache with
the contents of the route cache. It also adds the possibility
to limit route caches to certain address families.

241b2b83ba New netem funtionality and TBF fix
New netem-related functionality:
Added ability to save new settings to the kernel. In netem.c, the
netem_get_opts() stub has been replaced with netem_build_msg() which
manipulates the nl_msg data directly and returns an error code instead
of a new nl_msg. Modifications to qdisc_build() in qdisc.c and struct
rtnl_qdisc_ops were necessary for this.
Added support for getting/setting corruption probability/correlation.
Added support for setting a delay distribution.

Fixed tbf_msg_parser() to call tbf_alloc() instead of tbf_qdisc() to
prevent a seg fault.

535e831622 Big routing code rework (API/ABI BREAK!)
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.

4649886288 Represent default route with destination address length zero
So far the destination address for default routes was NULL
which complicated the handling of routes in general. By
assigning a address of length zero they can be compared
to each other.

This allows the cache manager to properly handle default
routes.

3040a1d625 Export interface to define caches
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.
