ACL patch

2020-05-02 Thread Christos Zoulas 


Hi,

The following patch ports the FreeBSD FFS ACLS (both posix1e and nfs4) to
NetBSD. Comments? I will let this sit for a week or so and then commit it
if I don't hear screams.

I fixed the "current thread confusion" by setting the current
thread and reloading the symbol file in gdb, this works as
expected:

$ gdb netbsd.gdb
(gdb) target kvm netbsd.666.core
(gdb) source /usr/src/sys/gdbscripts/modload
(gdb) modload
(gdb) where
