dsl b8fbaf8c4b Change the way that emulations locate files within the emulation root to ... avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.		2007-04-22 08:29:55 +00:00
