unidentified audit msg

[David-Alexandre Davidson]

Hi, I recently observed a strange behavior of selinux while serving
web content over a smb share. The result was some images not showing
with httpd returning a forbidden status. After verifying all other
possible issue. I found this strange entry in my audit.log file :

type=AVC msg=audit(1150863068.013:12309): avc:  denied  { 0x100000 }
for  pid=14365 comm="httpd" name="stock" dev=cifs ino=361051
scontext=root:system_r:httpd_t:s0 tcontext=system_u:object_r:cifs_t:s0
tclass=file
type=SYSCALL msg=audit(1150863068.013:12309): arch=40000003

fsuid=48 egid=48 sgid=48 fsgid=48 comm="httpd" exe="/usr/sbin/httpd"
type=CWD msg=audit(1150863068.013:12309):  cwd="/"
type=PATH msg=audit(1150863068.013:12309): item=0
name="/home/testeur/var/www/manage/public_domains_icons/CrystalClear-GNOME-1.0.0/22x22/stock/stock-help.png"
flags=0

Is there someone who knows what this 0x100000 permission is? I tried
to compile a loadable module with the corresponding allow statement
(I'm on core 5) but the 0x100000 does not appear to be a valid element
and it fails to compile. I observed this behavior on different
files(for example in this msg the denial occur on the "stock" folder
of the path, but I've seen it on the 22x22 folder as well). Restarting
the system results in some file that were forbidden to show up without
reason and some that were ok to just stop being served by httpd
(always giving the 0x100000 dennial)

At first I suspected a problem with the smb (cifs) mount but
everything work perfectly if I try to access the mount directly. Then
I suspected apache but the forbidden status code seems directly
related to the audit msg.

Anyone is welcome to help, I'm quite lost on that matter.
