[New-bugs-announce] [issue11912] Python shouldn't use the mprotect() system call

[Nils Breunese]

New submission from Nils Breunese <nils at breun.nl>:

When I try to run iotop [0] on CentOS 5.6 on a kernel with grsecurity [1] then iotop won't start because grsecurity is blocking Python because of its use of the mprotect() system call.

Please see http://www.atomicorp.com/wiki/index.php/ASL_FAQ#grsec:_denied_RWX_mprotect for more information. The authors of this hardened Linux kernel suggested to file a bug with Python because using mprotect() is apparently a very bad thing to do.
