* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-1613-91/+13

This is not done manually, but by running the following script: --- #!/bin/bash # Tool to drop license comments, adding SPDX license identifiers, while preserving # copyright comments.

* route/qdisc: adjust API for 64 bit rate/ceil support for htb classThomas Haller2019-09-011-4/+11
| | | | | | | | | | | | | | | | - existing API/ABI must stay unchanged. We cannot change parameter types. Ad most we can add new variants that support 64 bit integers. - rtnl_tc_calc_txtime64() and rtnl_tc_calc_bufsize64() are trivial. We should not blow up the public API of libnl for such a thing. If the users needs it, they can just reimplement it. - getters should return an error code. Especially if the return type does not support encoding an error there. - don't add separate rs_rate64/rs_ceil64 field. Instead, extend the "rs_rate" field of "struct rtnl_ratespec" to 64 bits. It's internal API.
* Add 64bit rate/ceil support for htb classd0u92019-09-011-4/+4
| | | | | Htb class has already supported 64bit rate and ceil settings for times. Now, in this patch, we grant this ability to libnl library.
* lib/qdisc: avoid BUG() in "lib/route/qdisc/mqprio.c"Thomas Haller2018-10-091-1/+1
| | | | | | | | | | BUG() raises an assertion. It seems overly harsh. For example, rtnl_tc_data() can fail if we fail to allocate memory. Asserting against that, makes libnl3 not out-of-memory safe. Just return a regular error.

* route: add separate function to set netem qdisc delay distributionSteffen Vogel2017-12-201-0/+1
| | | | | | | | | A new function rtnl_netem_set_delay_distribution_data() has been added to allow the user to pass the delay distribution directly without loading it from a file. In conjunction with the maketable code (see iproute2 / NISTnet) this can be used to generate and load custom delay distributions on the fly.
* include: don't include kernel headers in public libnl3 headersThomas Haller2017-03-021-0/+2
| | | | | | | | | | | | | | | | | It would be desirable not to include kernel headers in our public libnl3 headers. As a test, remove all those includes, and fix compilation by explicitly including the kernel headers where needed. In some cases, that requires forward declaration for kernel structures, as we use them as part of our own headers. Realistically, we cannot drop those includes as it probalby breaks compilation for users that expect to get a certain kernel header when including a libnl3 header. So, this will not be done and the includes will be restored in the next commit. Do this step to show how it would be and to verify that we could build with such a change. The reason not to do this is backward compatibility (at compile-time).

* Support plug qdisc - queue traffic until explicit releaseShriram Rajagopalan2012-02-141-0/+30
| | | | | | | | | | | | | | | | | | | | | | | The plug qdisc supports two operations - plug and unplug. When the qdisc receives a plug ("buffer") command via netlink request, packets arriving henceforth are buffered until a corresponding unplug command is received. Depending on the type of unplug ("release_one" or "release_indefinite"), the queue can be unplugged indefinitely or selectively. The plug qdisc allows a user to implement network output buffering (aka output commit), used commonly in checkpoint based fault tolerance systems. It also supports a general purpose queue plug/unplug functionality. The associated kernel module is available in David Miller's net-next tree, commit: c3059be16c9ef29c05f0876a9df5fea21f29724f This patch introduces userspace tools and API, to control the qdisc via netlink messages.
