* Reduce the time it takes the kernel to install a new PF config containing a ↵Patrick Kelsey2019-02-111-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | large number of queues In general, the time savings come from separating the active and inactive queues lists into separate interface and non-interface queue lists, and changing the rule and queue tag management from list-based to hash-bashed. In HFSC, a linear scan of the class table during each queue destroy was also eliminated. There are now two new tunables to control the hash size used for each tag set (default for each is 128): net.pf.queue_tag_hashsize net.pf.rule_tag_hashsize Reviewed by: kp MFC after: 1 week Sponsored by: RG Nets Differential Revision: https://reviews.freebsd.org/D19131 Notes: svn path=/head/; revision=343995
* Extended pf(4) ioctl interface and pfctl(8) to allow bandwidths ofPatrick Kelsey2018-08-221-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2^32 bps or greater to be used. Prior to this, bandwidth parameters would simply wrap at the 2^32 boundary. The computations in the HFSC scheduler and token bucket regulator have been modified to operate correctly up to at least 100 Gbps. No other algorithms have been examined or modified for correct operation above 2^32 bps (some may have existing computation resolution or overflow issues at rates below that threshold). pfctl(8) will now limit non-HFSC bandwidth parameters to 2^32 - 1 before passing them to the kernel. The extensions to the pf(4) ioctl interface have been made in a backwards-compatible way by versioning affected data structures, supporting all versions in the kernel, and implementing macros that will cause existing code that consumes that interface to use version 0 without source modifications. If version 0 consumers of the interface are used against a new kernel that has had bandwidth parameters of 2^32 or greater configured by updated tools, such bandwidth parameters will be reported as 2^32 - 1 bps by those old consumers. All in-tree consumers of the pf(4) interface have been updated. To update out-of-tree consumers to the latest version of the interface, define PFIOC_USE_LATEST ahead of any includes and use the code of pfctl(8) as a guide for the ioctls of interest.

* Add ALTQ(9) support for the CoDel algorithm.Luiz Otavio O Souza2015-08-211-0/+5
| | | | | | | | | | | | | | | | CoDel is a parameterless queue discipline that handles variable bandwidth and RTT. It can be used as the single queue discipline on an interface or as a sub discipline of existing queue disciplines such as PRIQ, CBQ, HFSC, FAIRQ.

* Move ALTQ from contrib to net/altq. The ALTQ code is for many yearsGleb Smirnoff2015-04-161-0/+261
discontinued by its initial authors. In FreeBSD the code was already slightly edited during the pf(4) SMP project. It is about to be edited more in the projects/ifnet. Moving out of contrib also allows to remove several hacks to the make glue. Reviewed by: net@ Notes: svn path=/head/; revision=281613
