bgrayson 2721f671ab - Be really paranoid. Any time we open a file that is in /proc, run 
fstatfs() on the open file to verify that no intruder has mounted
  something on portions of /proc.  This will catch, for instance,
  "mount_null /tmp /proc/1378".  We already do 5 syscalls per
  process, so one more won't hurt :) ...  and safety is better than
  performance when ps is otherwise broken.
- Also added a few close()'s at early returns, to avoid chewing up fd's.

bgrayson 05e0706ac9 Minor fixes: 
1.  Use statfs() to verify that /proc is a procfs.
2.  Add -K option to disable /proc-based method.
3.  Make warnings less verbose, but still accurate.

tron 0ee6a66c30 Add missing prototype so that this actually compiles. 1999-03-27 15:22:17 +00:00
bgrayson be8534f744 Added experimental fallback /proc-based lookup. Warnings are printed when the 
fallback method is used, as the results could be untrustworthy if an
intruder is present.  It is highly likely that NetBSD-1.5 will have
an improved kvm interface for reading process information, at which
point this code can be garbage-collected.  Also added a word to the
man page -x option description while I was here.

mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

garbled f124765044 More and more .Os cleanups. .Os is defined in the tmac.doc-common file, 
so we shouldn't override it with versions in the manpages.  Many more to
come.

kim 26cc4401e8 Fixed segfaulting for "ps -T". There is no optarg with -T, so instructions 
under label "tty:" need to use ttname instead.

tv 8cfe18e8d3 Add CWARNFLAGS+=-Wno-format-y2k. 1998-08-25 15:13:16 +00:00
ross 17dbc471f0 Kill the CFLAGS+=-Wno-format-y2k which will go, for now, into bsd.sys.mk 
It wasn't working anyway, although that could have been fixed by moving it
down below the .include <bsd.prog.mk> line.

It's not completely clear that this usage of %y is in fact y2k-safe, it
seems safer for now to have a single XXX option in bsd.sys.mk, and we need
to rev this anyway for -Wno-uninitialized

mrg 80efe80bc9 - change setgid kmem programs (that lend themselves to this) so setegid(getgid()) 
and the top, and then set the effective gid back to kmem around the call to
  kvm_openfiles().  this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
  kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places

avail_end - avail_start difference which is only correct on machines with
contiguous memory).
