CVS commit: src/sys/kern

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Thu Apr 26 20:58:37 UTC 2007

Modified Files:
        src/sys/kern: vfs_lookup.c

Log Message:
Be a little less over-zelous about converting ".." at the emulation root
to the real root.  Rather that do the check inside lookup() - where it
applies to to every ".." in a pathname, explicitly check the start of
the caller-supplied buffers and any absolute symbolic links.
Note that in the latter case the re-search from the real root is supressed.
Should fix PR kern/36225
