/usr and /usr/lib64 directories are world writable

/usr and /usr/lib64 directories are world writable


I noticed that /usr and /usr/lib64 directories are world writable (mode 777), I'm using MPSS 3.1.2/4.

I commented out following line from /opt/intel/mic/ofed/ofed.filelist and after reboot permissions are how they should be.

# MPI fix
#slink /usr/lib64/libibverbs.so libibverbs.so.1.0.0 777 0 0

And symbolic link is there.

[root@m1-mic0 lib64]# ls -la libibverbs.so.1*
lrwxrwxrwx    1 root     root            19 Jan  1  1970 libibverbs.so.1 -> libibverbs.so.1.0.0
-rwxr-xr-x    1 root     root         54296 Feb 27 02:29 libibverbs.so.1.0.0

So what is purpose of that MPI fix?

Thanks for pointing this out. I don't know of any reason why. I'm checking with the developers.


A fix was put into MPSS 3.3.28649 so that by default the permissions will be set to 755.
