Yeah, it's the same file as the one in the policy sources
(targeted/src/policy), which comes from the
selinux-policy-targeted-sources directory. You shouldn't need that
unless you have to customize the policy, which doesn't sound necessary
yet.
/var/www(/.*)? system_u:object_r:httpd_sys_content_t
It looks as if the httpd policy needs the logs to be a different type:
Mine says the same...
But there is a
/etc/httpd/logs system_u:object_r:httpd_log_t
And this:
/var/log/httpd(/.*)? system_u:object_r:httpd_log_t
I suppose either would work, since httpd_t can append to httpd_log_t and
httpd_runtime_t. httpd_log_t looks like the proper one to use.
But what puzzles me is why only this one log directory....all the others
like it work...
This is with httpd_unified set to true?
Yes actually mine says "active"
AIUI, it must be set to true,
if httpd_t can append to httpd_sys_content_t.
For 'ls -Z /var/www' are all the directories essentially the same
permissions? I'm not thinking the problem is regular UNIX permissions
because you got an AVC denial ... something is fishy.
ls -Z /var/www

Does it error if you change the type of the log files to httpd_log_t?
I.e.,
chcon -R -t httpd_log_t /var/www/spokanewines.com/logs/*
Issued the above command and then service httpd start
Nov 30 13:31:29 webmail kernel: audit(1101850289.759:0): avc: denied {
append } for pid=2585 exe=/usr/sbin/httpd name=error_log dev=dm-0

tcontext=system_u:object_r:httpd_sys_content_t tclass=file

-rw-r--r-- root root system_u:object_r:httpd_log_t error_log
Can you send in the avc: denied errors that you are getting? I can't
imagine how this would be a policy bug, but it's worth looking into.
