OK, it's time for me to bite the bullet and learn something about SELinux rather than blithely disabling it on my Fedora installations.
The wiki and several forum posts report that the SqueezeCenter 7.3.4 rpm is compatible with SELinux on Fedora. E.G.: http://wiki.slimdevices.com/index.php/SqueezeCenterRPM#SELinux Yet when I install squeezecenter-7.3.4-0.1.28402.noarch.rpm on Fedora 12, SELinux immediately pops up a warning: Code: -------------------- Summary: SELinux is preventing /usr/bin/perl from loading /usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so which requires text relocation. Detailed Description: The squeezecenter-s application attempted to load /usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. You can configure SELinux temporarily to allow /usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so to use relocation as a workaround, until the library is fixed. Please file a bug report. Allowing Access: If you trust /usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so'" Fix Command: chcon -t textrel_shlib_t '/usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so' Additional Information: Source Context unconfined_u:system_r:initrc_t:s0 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/share/squeezecenter/CPAN/arch/5.10/i386 -linux-thread-multi/auto/DBD/mysql/mysql.so [ file ] Source squeezecenter-s Source Path /usr/bin/perl Port <Unknown> Host fedorabox Source RPM Packages perl-5.10.0-82.fc12 Target RPM Packages squeezecenter-7.3.4-0.1.28402 Policy RPM selinux-policy-3.6.32-56.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execmod Host Name fedorabox Platform Linux fedorabox 2.6.31.6-166.fc12.i686.PAE #1 SMP Wed Dec 9 11:00:30 EST 2009 i686 i686 Alert Count 1 First Seen Tue 22 Dec 2009 11:46:37 AM MST Last Seen Tue 22 Dec 2009 11:46:37 AM MST Local ID 8a03144e-ee54-4775-99f6-2a74c2ebf6da Line Numbers Raw Audit Messages node=fedorabox type=AVC msg=audit(1261507597.970:26333): avc: denied { execmod } for pid=2814 comm="squeezecenter-s" path="/usr/share/squeezecenter/CPAN/arch/5.10/i386-linux-thread-multi/auto/DBD/mysql/mysql.so" dev=sda2 ino=263533 scontext=unconfined_u:system_r:initrc_t:s0 tcontext=system_u:object_r:lib_t:s0 tclass=file node=fedorabox type=SYSCALL msg=audit(1261507597.970:26333): arch=40000003 syscall=125 success=no exit=-13 a0=f91000 a1=19a000 a2=5 a3=bfb059e0 items=0 ppid=2784 pid=2814 auid=500 uid=489 gid=470 euid=489 suid=489 fsuid=489 egid=470 sgid=470 fsgid=470 tty=(none) ses=1 comm="squeezecenter-s" exe="/usr/bin/perl" subj=unconfined_u:system_r:initrc_t:s0 key=(null) -------------------- I've got NO experience with trying to configure SELinux. Anyone care to give me a couple of pointers to get me started? (Other than blindly following the instructions in the error message...is that the appropriate thing to do?) Are folks of the opinion that SELinux is useful, worthy and worth the effort? -- gharris999 ------------------------------------------------------------------------ gharris999's Profile: http://forums.slimdevices.com/member.php?userid=115 View this thread: http://forums.slimdevices.com/showthread.php?t=72938 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
