Description of problem:


Dec  5 17:01:02 cappello kernel: audit(1165363262.476:151): avc:  denied  {
execheap } for  pid=4276 comm="MATLAB" scontext=user_u:system_r:unconfined_t:s0
tcontext=user_u:system_r:unconfined_t:s0 tclass=process

Is there any way other than allow_execheap=1 to give MATLAB execheap permission?

No.  You could write policy for it.  Sorry about loosing this bug in the stream
of bugzillas.
Comment 2 Daniel Walsh 2007-02-14 10:08:27 EST
This should really be reported as a bug in MATLAB.
Comment 3 Daniel Walsh 2007-02-14 10:12:27 EST
One evil hack that you could do would be to assign java_exec_t to the executable.
Jave currently has the execheap permission.

Not a bad idea actually, since I think it is the Java parts of matlab that's
causing the problem.
Comment 5 Daniel Walsh 2007-02-14 15:17:09 EST
What is the path to matlab?
Comment 6 Orion Poplawski 2007-02-16 13:55:10 EST
Well, that's tricky because you can install it anywhere.  In our case, we
install it on our NFS server which causes problems with SELinux.  Or in
/opt/local/matlab on our laptops, or at least symbolic links are there that
point to the real install in /export/local/matlab_r2006a (or whatever version).
 The binary is then in some location like /opt/local/matlab/bin/<arch>/MATLAB.

Also, looks likes this is in the policy:

/usr/local/matlab.*/bin/glnx86/libmwlapack\.so --

I've added the following as well:
