Fix for ticket #240: The samhain_kmem kernel module should be loaded earlier

File size: 92.8 KB
Line 
12.8.3:
2        * init scripts: load samhain_kmem.ko before samhain starts
3        * slib.c: eliminate mutex from sl_create_ticket()
4        * sh_entropy.c: move pthread usage out of child
5        * sh_hash.c, sh_pthread.c, sh_pthread.h: sh_hash_hashdelete()
6          needs deadlock detection, may be called from within sh_hash_init()
7          via atexit handler on error condition
8        * sh_suidchk.c, sh_calls.c, sh_calls.h: need a nosub version of lstat()
9          to use with relative path after chdir()
10        * samhain.c, sh_calls.c, sh_calls.h: only run (l)stat() in subprocess
11          after reading config file (to allow disabling)
12        * sh_unix.c: run sh_sub_kill() in parent after forking the daemon
13        * fix zeroing of result from getnameinfo() (problem reported by Richard)
14        * fix spurious warnings about unsupported address family (reported
15          by N Silverman)
16        * option to run lstat/stat in subprocess to avoid hanging on NFS mounts
17          (off by default)
