Modified Files:
src/sys/kern: subr_pool.c
src/sys/sys: pool.h
Log Message:
Add support for detecting use-after-frees in KASAN. We poison each freed
buffer, any subsequent read or write will be detected as illegal.
* Add POOL_CHECK_MAGIC, which is disabled under KASAN, because the same
detection is done in a better way.
* Register the size+redzone in the pool structure, to reduce the overhead.
* Fix the CTOR/DTOR check in KLEAK, the fields are never NULL.
