766487d941 Too many vnode ops were marked as bad op, but could happen in practice. 
Change them to genfs_eopnotsupp.

e0f973ee3b Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

a79a3ca472 Fix a reversed argument which caused procfs_checkioperm() to always return 
"OK".  Add a few comments to avoid further confusion.

945beb8d63 Move procfs_checkioperm() from procvs_subr.c to procfs_mem.c, since _subr is 
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?

f9777e4a1c Fix the procfs hole described on current-users, similar to a fix for 
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.

a149ed59e4 Eliminate use of dtom() in the handing of UNIX domain sockets. Add an 
"unp_addrlen" member to the unpcb, and use it when copying the socket
name.  This eliminates that last uses of dtom() in the system.

701f15db33 Reinstate P_FSTRACE, with different semantics: 
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.

217c4e14ea Fix several deficiencies, as compared to ptrace(2): 
* Did not check for P_SUGID on ATTACH.
* Did not check for tracing of init on ATTACH.
* Did not turn off single-step mode on RUN or DETACH.
* Might have screwed up reparenting in some cases.
* Allowed anyone to detach the process.

90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to 
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
