kardel e386d70092 accept either "time_second" or "time" as kernel timevariable in 
order to support common userland in enviroments where
timecounter kernels and non timecounter kernel co-exist
(e.g. xen & i386)
 2006-07-09 06:43:16 +00:00
kardel 75418af90c support timecounters (struct time gone, use time_second then) 2006-06-07 20:56:19 +00:00
hubertf f500b89c3d Free some allocated memory in the failure case when trying to 
fetch the panic string.

Fixes Coverity CID 1856.

dsainty 4b46224291 Added -n option, which tests for a present core but doesn't write it 
to disk or clear it (does 'nothing').

tls e8092c77bc Fix an integer overflow that prevented saving cores from machines with 
more than 2GB of RAM.

"dumpsize" in the on-disk core header is in pages, but, unfortunately,
c.size in our kcore format is an unsigned 32-bit int, gross.

We sleaze it, using a 64-bit int internally here and handing it to
libkvm as a *signed* 32-bit int.  Won't always work, but shouldn't be
broken any worse than it is now, and sometimes work better.

We must fix the kcore format and libkvm.

christos 6bd1d6d4db Replace the statfs() family of system calls with statvfs(). 
Retain binary compatibility.

christos 99319b80db Give a 60 day leeway instead of a week when judging if the dumptime is valid. 
7 days is too short when you are debugging time problems.

lukem fa5157d9fb explicitly set the default compression level to 1 (from the implicit 6), 
because it's significantly faster and doesn't use that much more disk space.
 2001-09-12 03:14:08 +00:00
lukem fd08f59ac0 Add "-Z level" to control the compression level that -z uses (which 
defaults to -Z 6).  Depending on the relative speed of the CPU
versus disk, "-zZ1" might be faster than no compression at all.

simonb 1547b056d0 If the position of the formatted panic string can be found in the 
message buffer, use that instead of the raw panic string.

Suggested by Jason Thorpe eons ago.

martin 1bb8e47f65 Make option flag variables static. This avoids a conflict between 
'int compress' in savecore.c and the function 'compress' in libz.
Gnu ld 2.10 (with BFD 2.10) used on sparc64 warns this conflict
(symbol "compress" changed size).

lukem 834e92eedc Bump the field width of `K to go' from 6 to 8; some systems have more 
than 999999 KB of RAM... (this will suffice until it's common to have
~ 100 GB of RAM :)

on request of Andrew Doran.

swap partition), instead of "kvm_dump_mkheader: Pread: Invalid argument".

wiz ba968ca2e4 de-__P(), and generally try to be more conforming to the new NetBSD style. 
Use %m in syslog strings where appropriate.
Reduce warnings with WARNS=2.

wiz e7fe5f1380 Fix argument handling, which was pretty broken. 
If sysctl supports it, try to get the kernel name with CPU_BOOTED_KERNEL.
Get current kernels version string in all cases.
Adapt some error messages to the correct kernel name.

leo 08b137da1d Omit kd_live argument to kvm_dump_mkheader(). 1996-03-18 21:16:05 +00:00
leo a10137a7e3 New libkvm/savecore implementation. With the following differences: 
1) savecore will not access the dump or live-kernel directly. It
        will always use the kvm-functions. Allowing it to work on kernels
        that don't have a 1-1 PA-VA mapping.
     2) the kvm-lib has some additional functions to accomplish 1
          - kvm_dump_mkheader()
          - kvm_dump_wrtheader()
          - kvm_dump_inval()
     3) the file formats of the dump generated by the kernel and the dump
        generated by savecore have been changed. The file format now looks
        like the format produced for 'normal' core dumps.
Ports not yet supporting the new kvm-format will be using libkvm.old/
savecore.old for the time being.

cgd 83b019efaa set dumpsize in dump_exists(), not save_core(), so that minfree check 
works again.  solves pr 1257, but sets dumpsize earlier than suggested
in that pr, so that dumpsize is set if a core doesn't appear to be
present (because dumpsize would be used if the '-f' flag is given).
