9bcaf304c6 Fixed missing cross reference to kvm_getfiles.
This man page may be overdoing the cross references by referencing
man pages that are just links to other pages that are referenced.

kvm_uread() is still completely undocumented in kvm*.3.

bc701368b4 <sys/types.h> isn't a prerequisite for <kvm.h>. 1998-12-16 19:12:14 +00:00
Bruce Evans
424a876474 The previous commit was bogus. <stdlib.h> was never a prerequisite
for <kvm.h> or kvm_getloadavg(), and <sys/types.h> was only a
prerequisite for <kvm.h> when <kvm.h> was broken.

b245b90a64 Declare size_t and ssize_t if they are not already declared, so that
<kvm.h> is self-sufficient again.

Moved typedefs and forward struct declarations out of __BEGIN_DECLS/
__END_DECLS.

Don't comment out the prototype for kvm_uread().  This was a 4 year
old kludge for previous breakage of self-sufficiency.  The prototypwe
was broken instead.

Fixed bitrot (const poisoning) in the type of kvm_uread().

Fixed order of the declaration of kvm_uread().

60160c5e50 Adjust for kern.ps_strings and PS_STRINGS not being a pointer. This
fixes a type mismatch in the call to kvm_uread().  The bug has gone
undetected for almost 3 years because kvm_uproc()'s protoype has been
disabled for almost 4 years.

Trust sysctlbyname() to work properly if it succeeds.

Fixed style bugs in revs. 1.19 and 1.22.

b2d3d0f097 Avoid the "Cannot allocate memory" problem that appears on heavily
loaded systems by retrying the sysctl() with a larger buffer if it
fails with ENOMEM. For good measure, allocate 10% more memory than
sysctl() claims is necessary.

e8420087b0 Replace memory leaking instances of realloc with non-leaking reallocf.
In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x).  Per ANSI-C, this is
guaranteed to be the same thing.

I've been running these on my system here w/o ill effects for some
time.  However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the

d7fb4b13b9 Fixed bugs in the conversion of kvm to to use procfs in rev.1.3. All
are in kvm_uread():
- the setting of errno before checking it in the lseek() was lost.
- EOF handling was lost.  kvm_uread() retried forever on EOF.  EOF is
  not really an error, but report it one as in rev.1.2.
- reporting of errno after a read error was lost.

Fixed style bugs in rev.1.3 and rev.1.12.

Not fixed: errno is not reported after lseek() failures.

2f85bf6e8e Implement virtual-to-physical address mapping for the kvm library on
dead kernel debugging.  The previous code was a "do nothing".

The most obvious side effect of this is that you can now do things like
this and reasonably expect them to work:
  dmesg -M /var/crash/vmcore.3 -N /var/crash/kernel.3
  ps -axl -M /var/crash/vmcore.3 -N /var/crash/kernel.3

A good deal of this was lifted from the gdb code to do this, as well as
from NetBSD's libkvm (which has completely different VM macros)

7350dd84a0 If the two recently added sysctl variables exist, use those rather than
the statically compiled PS_STRINGS and USRSTACK variables.  This prevents
programs using setproctitle from coredumping if the kernel VM is increased,
and stops libkvm users (w, ps, etc) from needing to be recompiled if only
the VM layout changes.

Given the right circumstances, a call to kvm_open can result in a core
dump.

The diff belows fixes this (note that this change is already in the
NetBSD code). Could somebody apply this?
