Hi,
I have run up2date to update many packages of my fc3 system. My system info:
RedHat FC3 linux, kernel 2.6.10-1.766_FC3, selinux enforced (targeted),
iptables enabled
selinux-policy-targeted: 1.17.30-2.19
Then, the root received the following mail:

I don't know which package's updating caused this problem. Then, I run:
# restorecon -R /etc/*
# restorecon -R /var/*
# restorecon -R /lib/*
# restorecon -R /usr/*
I got a lot of warning about sybolic links, that's probably okay. Now,
the problem is that the user qlily cannot login to squirrelmail. The
error message is:
Preference file, /var/lib/squirrelmail/prefs/qlily.pref.tmp, could not be
opened. Contact your system administrator to resolve this issue.
Check the files:
# ls -lZ /var/lib/squirrelmail/prefs/qlily.*
-rw-r--r-- apache apache system_u:object_r:var_lib_t
/var/lib/squirrelmail/prefs/qlily.abook
-rw------- apache apache system_u:object_r:var_lib_t
/var/lib/squirrelmail/prefs/qlily.pref
-rw-r--r-- apache apache system_u:object_r:var_lib_t
/var/lib/squirrelmail/prefs/qlily.pref.tmp
and the log shows:
Mar 2 15:49:03 pippo kernel: audit(1109800143.922:0): avc: denied {
write } for pid=1458 exe=/usr/sbin/httpd name=qlily.pref.tmp dev=hda2

tclass=file
....
qlily is the only user I created so far in the system. This user can
send/receive email through pine. To test the situation, I created another
user msnet. He can login to ssh console, but cannot login to
squirrelmail, the error message is:
You must be logged in to access this page
although the password is correct. his pref file is:
# ls -lZ /var/lib/squirrelmail/prefs/msnet.pref
-rw------- apache apache root:object_r:httpd_var_lib_t
/var/lib/squirrelmail/prefs/msnet.pref
What's wrong? What package updating caused this problem? How to fix the
problem?
Thanks a lot!
