-Subject: [PATCH] Issue #744 (part of Issue #743): Enforce sandbox with very
- long pathnames
-
-Because check_symlinks is handled separately from the deep-directory
-support, very long pathnames cause problems.  Previously, the code
-ignored most failures to lstat() a path component.  In particular,
-this led to check_symlinks always passing for very long paths, which
-in turn provides a way to evade the symlink checks in the sandboxing
-code.
-
-We now fail on unrecognized lstat() failures, which plugs this
-hole at the cost of disabling deep directory support when the
-user requests sandboxing.
-
-TODO:  This probably cannot be completely fixed without
-entirely reimplementing the deep directory support to
-integrate the symlink checks.  I want to reimplement the
-deep directory hanlding someday anyway; openat() and
-related system calls now provide a much cleaner way to
-handle deep directories than the chdir approach used by this
-code.
