and didnt match anything.  Dont make our caller think we succeeded.

simonb 0a7d3a1ff5 Add a K flag to the state information - K is for kernel thread or system 
process (ie, P_SYSTEM set in p_flag).  The L flag (locked in core) is
only used for non-P_SYSTEM processes.

simonb 643cb3c341 Don't check namelist when choosing to use the sysctl interface. 2000-06-16 03:51:00 +00:00
simonb d530ee00d1 Fix handling of "ps U<user>" where <user> ended it 't' - now if the 
first argument doesn't start with a '-' and ends in 't', the 't' only
gets converted to a 'T' (for listing processes on the current tty)
if it doesn't contain any other command line option characters that
take an argument.  Problem noticed by ITOH Yasufumi on tech-userlevel.

If the 'start' format was the last column, the width wouldn't be set
and started() output a zero length string instead of a string the right
length - fix header width calculations so the the last column is handled
the same all others.  This only showed up for 'start' because started()
knew that the column header is the same width and the field itself...

Update copyrights.

simonb 292b668867 Fix back-to-front assignment in tname() which meant that the column 
width would never autosize past the header ("TT") width.  Problem
noticed by Geoff Wing.
 2000-06-08 00:51:10 +00:00
simonb a98dd470c6 Calculate field widths on the fly so that all columns line up nicely 
and make more effective use of screen real estate when some columns
(eg USER and VSZ) didn't need the full default width.

simonb a717560d21 G/C evar() - now that everything is in the one structure it was exactly 
the same as pvar().
 2000-06-02 03:39:02 +00:00
simonb fd521aefe9 Use new sysctl/kvm interfaces. This will stop the "proc size mismatch" 
errors when internal kernel structures change size.  Also remove
the sgid bit - all live kernel data is accessed through the sysctl
interface.

abs 22cfbf2cbb If ps cannot get the terminal size from STDOUT, it tried STDERR and STDIN. 
What this does to the POLS when a script that is parsing ps output just happens
to run in a narrow terminal cannot be described in polite company.
If STDOUT is not a tty, leave width at 80.
 2000-04-29 00:18:48 +00:00
simonb 8384a1bbb8 Use tty "?" to select processes with no controlling tty and tty "-" to 
select processes with a revoked controlling tty.

Idea from SunOS/Solaris, suggested by Alexis Rosen.

simonb e7f8f72d9d Since we have an "extern.h", put all external variable declarations in 
that file and not sprinkled around various .c files.

jdolecek a5ae7c6ca4 command(): don't start using procfs_getargv() instead of kvm_getargv() 
just because the latter returned a NULL - that may normally happen,
when the process is, for example, a kernel thread

procfs_getargv(): if the name is brackened in '(' and ')', just
	return NULL immediately - the code in command() will DTRT
	and the output will be same for procfs- and kvm- based lookup
	in all cases

jdolecek e52880e76a getkinfo_kvm(): fix bug in previous - handled size_t i as if it would be signed 
saveuser(): don't check kd - if we get here, kd is never NULL
 1999-10-15 20:01:33 +00:00
jdolecek f848d2ec0c When using the procfs for extracting process information, extract 
also process start time, process arguments and session leadership status.

The procfs fallback is also used when kvm_openfiles() completely fails
(e.g. when /dev/mem is not readable).

Solves PR 7772, though the final implementation is different.

christos f3d0eddcde Add support for printing wide sigset_t properly. 1999-04-16 13:34:32 +00:00
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.
 1999-03-28 00:46:47 +00:00
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.
