nathanw 43634bc5ba Since kinfo_proc2 has many values that are 64-bit, ps needs to know 
that they're 64-bit, and grab them out of memory appropriately. Otherwise,
big-endian systems get the wrong end of the 64-bit value and lose.

Keywords affected: inblk, majflt, minflt, msgrcv, msgsnd, nivcsw, nsigs,
nswap, nvcsw, and oublk.

martin f95cd5a968 Use int32_t for temporary variables (instead of long), that is the same 
type as we get the data passed from the kernel. This avoids (missing)
sign extension bugs on LP64 systems and partly takes care of PR 15677.

We now print this values as negative seconds - still wrong, but that
probably is due to the simple way this values are acumulated in the
scheduler, causing negative times when ntpd steps time backwards.

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.

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.

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 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

Solves PR 7772, though the final implementation is different.

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:

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.
