* Add idiag-socket-detailsJoe Damato2013-07-253-1/+95
| | | | | | This small program lists all sockets on the system seen by netlink and serves as a simple example showing how to alloc an idiag msg cache and dump the objects in it.
* Add support for inet diag Netlink protocol.Joe Damato2013-07-191-1/+2
| | | | | | | | | | | | | - Inet diag allows users to gather low-level socket information. - This library provides a higher-level API for creating inetdiag requests (via idiagnl_connect and idiagnl_send_simple) and parsing the replies (via idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache). - Request and message objects provide APIs for accessing and setting the various properties of each. - This library also allows the user to parse the inetdiag response attributes which contain information about traffic class, TOS, congestion, socket memory info, and more depending on the kernel version used. - Includes doxygen documentation.

* "%llu" replaced with "%" PRIu64Коренберг Марк (дома)2012-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | | On some architectures, uint64_t is defined as: typedef unsigned long long int __u64; on another architectures as: typedef unsigned long int __u64; So, according to man 3 printf, uint64_t should be printed as "%llu" on some architectures, and as "%lu" on another. The same for scanf. To eliminate that challenge, there is inttypes.h, in which appropriate constants are defined for current architecture. 32-bit types (and even 16 and 8 bit types) should be printed using such constants if printed variable defined as uint_XXXt or intXXXt type. But in reality 32-bit and less types does not gain run-time error (except in scanf), because they pushed to stack as 32-bit values at least. So, I decide not to fix that.

* Fix types-related warnings based on clang diagnosticsКоренберг Марк2012-06-131-3/+11
| | | | | | | | | | | | | | | | | 1. Fix some places where unsigned value compared < 0 2. Fix obsolete %Z specifier to more portable %z 3. Some erroneous types substitution 4. nl_msec2str() - 64-bit msec is now properly used, Only safe changes. I mean int <--> uint32_t and signed/unsigned fixes. Some functinos require size_t argument instead of int, but changes of signatures of that functions is terrible thing. Also, I do not pretend for a full list of fixes. Just to shut up clang -Wall -Wextra One more thing. ifindex. I don't change that because changes will be too big for simple fix.
* genl: Support registration of families without depending on cachesThomas Graf2012-06-011-2/+2
| | | | | | | | | | | | Introduces the functions genl_register_family() and genl_unregister_family() to register a Generic Netlink family which does not implement a cachable type. API users can direct received messages into genl_handle_msg() which will validate the messages and call the callback functions defined in the commands definition. See test/test-genl.c for an example on how to use it.
* FTBFS with musl libc: Missing includesIsaac2012-05-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, libnl 3.2.9 does not build with musl libc, without patching. I' using a current musl libc (http://www.etalabs.net/musl/) with linux 2.6.32 headers. At first there were a couple problems on the musl side, but those are resolved. However, I found some other issues: First, two files were missing #include <byteswap.h>: lib/netfilter/log_msg.c lib/netfilter/queue_msg.c These files used __bswap_64 (which should be bswap_64), a macro declared in byteswap.h Second, I got this error after fixing that: In file included from nf-queue.c:16: ./include/linux/netfilter.h:53: error: field in has incomplete type ./include/linux/netfilter.h:54: error: field in6 has incomplete type I found that src/nf-queue.c is missing an #include <netinet/in.h> Attached is a patch which resolves these issues. I've tested with both musl and glibc, and it builds cleanly on both.

* bonding: API to create/enslave/releaseThomas Graf2011-09-163-1/+98
| | | | | | | | | | | | | | Although it has been possible to create bonding devices, enslave and release using the regular link API. The added API simplifies usage and hides some of the compatibility logic. F.e. enslave() and release() will both verify that the master assignment has in fact been changed and return -NLE_OPNOTSUPP if it did not. Also the API will make sure to use RTM_NEWLINK or RTM_SETLINK depending on what is availble. Examples are provided in src/ as nl-link-enslave.c and nl-link-release.c

* Switch to libtool versioning systemThomas Graf2011-09-131-7/+10
| | | | | | | | | | | | | | | | | | 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)

* Deprecate rtnl_qdisc_foreach_child() and rtnl_qdisc_foreach_cls()Thomas Graf2011-03-241-1/+17
| | | | | | | | | Their usage is not completely safe, it is not possible to handle the out of memory situation of the allocate filter. It is very unlikely for this to cause any problem though. The functions are still accessible but gcc will warn about their deprecation.

* classid auto generation if provided tc name does not existThomas Graf2010-11-0110-17/+39
| | | | | | | | | | | | | | | | Manually editing etc/libnl/classid before adding tc objects is a pain. This patch adds code to attempt auto generating a unique tc id which will then be assigned to the provided name and added to the classid file. This will make the following commands work with prior definitions of the names "top" and "test" sudo sbin/nl-qdisc-add --dev eth0 --parent root --id top htb sudo sbin/nl-class-add --dev eth0 --parent top --id test htb --rate 100mbit It will generate the following ids automatically: 4001: top 4001:1 test
* src/nf-queue: revert nonsensical changePatrick McHardy2010-10-281-24/+0
| | | | | | | | | | | | The only part of commit d378220c (src/nf-queue.c: cleanup and improve performance of test program for NF_QUEUE) that actually makes sense is the increase in receive buffer size. Issuing verdicts for IDs not delivered to userspace is a wasted effort since the kernel drops packets itself when netlink message delivery fails. This would actually have been noticed by a return value of -ENOENT if the result of nfnl_queue_msg_send_verdict() would have been checked. Signed-off-by: Patrick McHardy <kaber@trash.net>
