This showed up when doing heavy UDP throughput on SMP machines. The problem with this is because the 802.11 sequence number is being allocated separately to the CCMP PN replay number (which is assigned during ieee80211_crypto_encap()). Under significant throughput (200+ MBps) the TX path would be stressed enough that frame TX/retry would force sequence number and PN allocation to be out of order. So once the frames were reordered via 802.11 seqnos, the CCMP PN would be far out of order, causing most frames to be discarded by the receiver. I've fixed this in some local work by being forced to: (a) deal with the issues that lead to the parallel TX causing out of order sequence numbers in the first place; (b) fix all the packet queuing issues which lead to strange (but mostly valid) TX. I'll begin fixing these in a subsequent commit or five. PR: kern/166190 |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
