Bug 562010

Sumário:

SELinux is preventing /usr/autodesk/maya2010-x64/bin/maya.bin from loading
/usr/autodesk/maya2010-x64/lib/libDynSlice.so which requires text relocation.

Descrição detalhada:

[maya.bin tem um tipo permissivo (unconfined_execmem_t). Esse acesso não foi
negado.]

The maya.bin application attempted to load
/usr/autodesk/maya2010-x64/lib/libDynSlice.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/autodesk/maya2010-x64/lib/libDynSlice.so to use relocation as a workaround,
until the library is fixed. Please file a bug report.

Permitindo acesso:

If you trust /usr/autodesk/maya2010-x64/lib/libDynSlice.so to run correctly, you
can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/autodesk/maya2010-x64/lib/libDynSlice.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/autodesk/maya2010-x64/lib/libDynSlice.so'"

Comando de correção:

chcon -t textrel_shlib_t '/usr/autodesk/maya2010-x64/lib/libDynSlice.so'
