Re: [squid-users] Squid 3.1.10 CentOS : cache_swap_log (13) Permission Denied

Hum... it's difficult to understand...
After having deleted the cache_swap_log line, and modified the cache_dir
to /drive/squid_guard, audit.log finish with this :

type=AVC msg=audit(1355919099.367:139918): avc: denied { write } for
pid=1770 comm="squid" name="squid_cache" dev=dm-2 ino=3145729

tcontext=unconfined_u:object_r:etc_runtime_t:s0 tclass=dir
type=SYSCALL msg=audit(1355919099.367:139918): arch=c000003e syscall=2

egid=23 sgid=23 fsgid=23 tty=(none) ses=45 comm="squid"
exe="/usr/sbin/squid" subj=unconfined_u:system_r:squid_t:s0 key=(null)

uid and gid are :
[root_at_proxy-new ~]# id root
uid=0(root) gid=0(root) groupes=0(root)
[root_at_proxy-new ~]# id squid
uid=23(squid) gid=23(squid) groupes=23(squid)

It seems that root:squid try to write-access to squid_cache... or I
misunderstand...

So, I've chowned -R root:squid /drive/squid_cache, and results are now :
[root_at_proxy-new drive]# ls -al /drive/
total 28
drwxr-xr-x. 4 root root 4096 18 d�c. 10:23 .
dr-xr-xr-x. 27 root root 4096 18 d�c. 11:29 ..

drwxr-xr-x. 66 root squid 4096 18 d�c. 10:31 squid_cache
