[PATCH 0/2] Environment variable security and tunables

[Siddhesh Poyarekar]

Hi,

Here's a patchset that fixes environment variable processing for AT_SECURE
processes.  The second patch removes GLIBC_TUNABLES from AT_SECURE processes
even when tunables are not built, to avoid passing on the variable (and hence
unsafe tunables) to child processes who may end up loading a glibc with
tunables enabled.

I will follow up with a patch for 2.24 to add GLIBC_TUNABLES to
unsecure-envvars.
