| |
In 2.6.3x, I am logging in as a root and running app from NFS mounted directory. The app crashed with 0 bytes core file (I have set "ulimit -c unlimited", so it's not an issue).
Proposed patch:
--- exec.c 2010-05-19 17:33:16.000000000 -0700 +++ exec.c.new 2010-05-19 17:33:07.000000000 -0700 @@ -1859,7 +1859,7 @@ * Dont allow local users get cute and trick others to coredump * into their pre-created files: */ - if (inode->i_uid != current_fsuid()) + if (inode->i_bytes != 0 && inode->i_uid != current_fsuid()) goto close_fail;
if (!file->f_op)
P.S. CC to my email, i am not on the list.
