state. Apparently it happens when both devices try to disconnect RFCOMM multiplexor channel at the same time. The scenario is as follows: - local device initiates RFCOMM connection to the remote device. This creates both RFCOMM multiplexor channel and data channel; - remote device terminates RFCOMM data channel (inactivity timeout); - local device acknowledges RFCOMM data channel termination. Because there is no more active data channels and local device has initiated connection it terminates RFCOMM multiplexor channel; - remote device does not acknowledges RFCOMM multiplexor channel termination. Instead it sends its own request to terminate RFCOMM multiplexor channel. Even though local device acknowledges RFCOMM multiplexor channel termination the remote device still keeps L2CAP connection open. Because of hanging RFCOMM multiplexor channel subsequent RFCOMM connections between local and remote devices will fail. Reported by: Johann Hugo <jhugo@icomtek.csir.co.za>
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 ``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.
