Description Göran Uddeborg 2010-08-06 07:53:25 EDT

Description of problem:
The current policy identifies two libraries, libnnz and libclntsh, in the directory for Oracle's Instant Client, /usr/lib/oracle, as needing text relocations.  There are however additional libraries in the directory.  All of them seems to require text relocations when you use them.  (Not surprisingly, I guess, they are probably built in the same broken way.)


Version-Release number of selected component (if applicable):
selinux-policy-2.4.6-279.el5_5.1

Some Oracle packages having the bug are:
oracle-instantclient11.1-basic-11.1.0.7.0-1
oracle-instantclient11.1-devel-11.1.0.7.0-1
oracle-instantclient11.1-jdbc-11.1.0.7.0-1
oracle-instantclient11.1-sqlplus-11.1.0.7.0-1


How reproducible:
Every time


Steps to Reproduce:
1.sqlplus
  
Actual results:
sqlplus: error while loading shared libraries: /usr/lib/oracle/11.1/client64/lib/libsqlplus.so: cannot restore segment prot after reloc: Permission denied


Expected results:
Login prompt from sqlplus

Sqlplus is a binary included in oracle-instantclient11.1-sqlplus.  It uses some of the libraries not yet singled out in the policy as an example.

Additional info:
Until we can get Oracle to build these libraries properly (yes, I've told them, and no I haven't got any reaction), I suggest the policy assumes all .so files in /usr/lib/oracle/… need textrel_shlib_t

/usr/lib/oracle/.*/lib/lib.*\.so(\.[^/]*)* …textrel_shlib_t…

Seems ok to me.

Comment 3 Miroslav Grepl 2010-09-09 09:11:48 EDT

Fixed in selinux-policy-2.4.6-283.el5.noarch

Comment 6 Tomas Straupis 2010-11-20 07:53:54 EST

I have the same problem after upgrade to Fedora14 (it was ok in Fedora13):

$ sqlplus
sqlplus: error while loading shared libraries: libsqlplus.so: cannot enable executable stack as shared object requires: Permission denied

Should I report it separately with product "Fedora"?

selinux-policy-3.9.7-10.fc14.noarch
