IPv6. Initialize it only once in def_policy_init(). Remove its initialization from key_init() and make it static. Remove several fields from struct secpolicy: * lock - it isn't so useful having mutex in the structure, but the only thing we do with it is initialization and destroying. * state - it has only two values - DEAD and ALIVE. Instead of take a lock and change the state to DEAD, then take lock again in GC function and delete policy from the chain - keep in the chain only ALIVE policies. * scangen - it was used in GC function to protect from sending several SADB_SPDEXPIRE messages for one SPD entry. Now we don't keep DEAD entries in the chain and there is no need to have scangen variable. Use TAILQ to implement SPD entries chain. Use rmlock to protect access to SPD entries chain. Protect all SP lookup with RLOCK, and use WLOCK when we are inserting (or removing) SP entry in the chain. Instead of using pattern "LOCK(); refcnt++; UNLOCK();", use refcount(9) API to implement refcounting in SPD. Merge code from key_delsp() and _key_delsp() into _key_freesp(). And use KEY_FREESP() macro in all cases when we want to release reference or just delete SP entry. Obtained from: Yandex LLC Sponsored by: Yandex LLC
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.
