christos b612016506 Print siginfo_t information when available. 2003-09-19 22:49:02 +00:00
agc 89aaa1bb64 Move UCB-licensed code from 4-clause to 3-clause licence. 
Patches provided by Joel Baker in PR 22365, verified by myself.

dsl fde07830ad Grok KTR_EXEC_ENV and KTR_EXEC_ARG. 
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-' (remove following) to valid -t arguments.
Dump data block of UNKNOWN trace points in hex + ascii.
Make first time output with -R 0 (instead of time since epoch).
Use svis() instead of vis() to get " escaped (as \") (needs fixed libc)
Correctly pass unsigned values to svis()
Update man pages.

dsl a99fe675ab Change back to print hex bytes. The 'word' print was completely broken 
on little endian systems.  It is also much easier to read misaligned
words in a straight byte hexdump.
Cut offset to 3 hex digits so that it fixs in 80 columns and still
leaves a tab at the start of 'continuation' lines.
The ktrace buffer is limited to 4k, so 3 digits is ample.

he ac678f8de2 On some ports, pointer differences are not ints, so do a cast 
before using such a result as a field width.
 2003-07-13 15:19:39 +00:00
manu cbfacd83b6 Make hexdump output fix in 80 char-wide terminal 2003-07-12 19:22:07 +00:00
manu e9383d7e5d Use the same code to display hexdump of GIO and MMSG (Mach Messages). 
While we are there, display offsets in the hexdump, it can be useful.
Remove size display in Mach Messages as user processes don't always
fill it correctly.

wiz b712736290 Add -x to usage output. 2003-07-11 13:06:11 +00:00
dsl 6ea05bcbfe Add a '-x' option to display GIO data blocks in hex and ascii (instead of 
vis(3) format).
Maybe there could be a heuristic to decide whether the data is printable...

fvdl 4fdb86c883 Back out previous. 2003-06-29 22:35:35 +00:00
martin 40ee31ef5e Since a caddr_t is (mis-)used as the lwp-id, cast it to intptr_t and use 
apropriate format string.
 2003-06-29 18:05:06 +00:00
darrenr d0ad455673 add appropriate hack to display ktr_buf as the lwpid if -L is supplied on 
the command line.
 2003-06-28 17:15:07 +00:00
dsl d9380c052a Print rval[1] if non-zero and present in the trace entry. 
To get both fd numbers for pipe().
 2003-05-15 12:57:54 +00:00
atatat 9658e47b39 Make "-m0" print no data, so that we agree better with the man page. 2003-01-30 21:43:26 +00:00
manu 6492e2171f Added support for dumping mach messages in ktrace/kdump. While we are 
there, KNFify a few functions.

wiz 287a8f7fb0 Sync usage with man page (and actual options). 2002-11-29 19:15:41 +00:00
jdolecek d51c5abbd9 signame(): if sig == 0, return name " 0", so that the result would be 
printed as:
   CALL  kill(0x1e4, SIG 0)
rathern than previous
   CALL  kill(0x1e4, SIG*unknown 0*)
 2002-11-28 16:18:49 +00:00
atatat a19ac80340 Add -N which inhibits translation of system calls numbers into names. 2002-11-27 21:26:57 +00:00

atatat 76df260979 Allow passing of the ktrace file as the last argument without a -f. 2002-09-27 20:31:44 +00:00
jdolecek d733dc2b03 Fix formatting of ktr_user entries so that values of individual bytes 
of ktrace record are treated as unsigned char, and printed using "%02x".
Change suggested in bin/17832 by Paul Goyette.
 2002-08-04 14:26:21 +00:00
atatat 40bd599a90 It's easy for ktrace can generate trace files that contain data from 
multiple processes, so let's add a "-p pid" option to kdump so that it
can pull out the data for one process easily.

christos 44788ce33b Fix translation in the native emulation. Noted by veego. 2002-04-08 20:15:59 +00:00
christos f600368b8f Provide hooks for signal number to name translation, and use them for kill 
and PSIG.

XXX[1]: This shows that signal emulation ktrace is slightly busted: posted
	signals should really be translated to the emulated ones instead of
	producing ktrace records with the signal numbers of the native
	emulation.
XXX[2]: There are other places where signal names can be displayed, but this
	is not done yet.

christos 35734831f9 reverse the notion of fancy, use plain, and increment it so that we can 
have multiple levels of plainness. I want to be able to display syscalls
numerically, for that use -nn. This is not documented as it is an wip.
 2002-02-12 22:22:37 +00:00
manu 1a6f014301 Cosmetic fix so that RET record after CALL execve get the appropriate syscall 
even if the emulation changed

itojun 08138ae451 avoid using "errno" as struct member name, to avoid conflict with errno.h. 
ok by jdolecek

jdolecek b837b700fa map linux ptrace op (number) to it's appropriate name - this is kind of hack, 
but turned out to be pretty usable for me

tron 7a721a2672 Prevent "kdump" from causing a segmentation fault if the io buffer that 
it's printing to stdout ends on a page boundary. Patch supplied by
Andrew Brown in PR bin/9983.
 2000-04-26 16:05:37 +00:00
jdolecek 470e7fc568 put setemul(), ectx_* & appropriate structures to separate file, to make it 
more easily sharable with ktruss(1)
 2000-04-10 09:13:45 +00:00
jdolecek 3d8f702c2b Keep track of what pid uses which emulation and ensure proper 
structures are used when decoding the ktrace records. This makes
kdump of ktrace -i output of a process executing binaries of various
emulations actually useful - before, the code used emulation structures
appropriate for last recently executed process, which is bogus.

cgd 0317ced760 fix decode of _IOR/_IOW/_IOWR: 'R' and 'W' were switched (i.e. _IOW ioctls
