2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------ From: Eric W. Biederman <[email protected]> commit 7b2a69ba7055da9a04eb96aa7b38c8e3280aaaa5 upstream. Because it caused a chroot ttyname regression in 2.6.36. As of 2.6.36 ttyname does not work in a chroot. It has already been reported that screen breaks, and for me this breaks an automated distribution testsuite, that I need to preserve the ability to run the existing binaries on for several more years. glibc 2.11.3 which has a fix for this is not an option. The root cause of this breakage is: commit 8df9d1a4142311c084ffeeacb67cd34d190eff74 Author: Miklos Szeredi <[email protected]> Date: Tue Aug 10 11:41:41 2010 +0200 vfs: show unreachable paths in getcwd and proc Prepend "(unreachable)" to path strings if the path is not reachable from the current root. Two places updated are - the return string from getcwd() - and symlinks under /proc/$PID. Other uses of d_path() are left unchanged (we know that some old software crashes if /proc/mounts is changed). Signed-off-by: Miklos Szeredi <[email protected]> Signed-off-by: Al Viro <[email protected]> So remove the nice sounding, but ultimately ill advised change to how /proc/fd symlinks work.
