in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.
For each leaf filesystem, add appropriate vfs_done routine.
UFS code, and I forgot to rename the "ihash" variable, causing
weird effects, because 3/4th of the UFS hash table would become
unreachable after procfs was loaded as an LKM.
process is about to exec a sugid binary.
To speed up things, use hashing for vnode allocation, like other filesystems
do. This avoids walking the whole procfs node list in the revoke case too.
Update coda to new struct lock in struct vnode.
make fdescfs, kernfs, portalfs, and procfs actually lock their vnodes.
It's not that hard.
Make unionfs set v_vnlock = NULL so any overlayed fs will call its
VOP_LOCK.
not included in a kernel without procfs, and it seems wrong to pull
all of procfs_subr.c in for just that one function. Perhaps this
should go into a new file instead?
FreeBSD by Sean Eric Fagan, but a bit different. This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):
(1) it's not owned by you, or is set-id on exec (unless
you're root), or
(2) it's init, which controls the security level of the
entire system, and the system was not compiled with
permanently insecure mode turned on.
Make NFS serving work (BUT DON'T USE "attach" TO /proc/*/ctl FOR NOW!!!)
Make `curproc' a symbolic link
Add `.' and `..' entries to the directories.
Return better guesses on the size of the files.
