Bug 553333

概述:

SELinux is preventing /usr/bin/kmplayer from loading
/usr/lib/libkmplayercommon.so which requires text relocation.

详细描述:

The kmplayer application attempted to load /usr/lib/libkmplayercommon.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/lib/libkmplayercommon.so to use relocation as a workaround, until the
library is fixed. Please file a bug report.

允许访问:

If you trust /usr/lib/libkmplayercommon.so to run correctly, you can change the
file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/libkmplayercommon.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/lib/libkmplayercommon.so'"

Fix 命令:

chcon -t textrel_shlib_t '/usr/lib/libkmplayercommon.so'
