65e4542fca I THINK this fixes 'make world'
I'll know as soon as I re-import it and compile it.. :-)
 There is no longer a 'pri' strict in the proc struct.
 the fields are scattered between the ksegrp and thread in question.

3daf63fc50 pre-emptively fix a KSE/M3 problem.
Make a slight change so that libkvm reaches the main thread via the
linked list, rather than assuming it is in the proc structure. Both
conditions are true in -current but only the first will be true in
the KSE M3 world.

fe42e96eff Finish cleanup in kvm.c revisions 1.10 and 1.11 -- mark sf (swapfile)
argument to kvm_open() and kvm_openfiles() as unused.

BSD didn't read swap since kvm.c CSRG revision 5.21 (u-area is pageable
under new VM.  no need to read from swap.)

The old !NEWVM code was removed in CSRG revision 5.23 (~ten years ago).

15d2f5f04f kern.ps_arg_max_cache is a long, not an int. I believe this is half of
what broke ps on ia64.  It probably also broke on alpha, but the fallback
method of using lseek/read on /proc/*/mem to read ps_strings seems to
work there.  It doesn't on ia64 yet.

b1fc0ec1a7 o Merge contents of struct pcred into struct ucred. Specifically, add the
real uid, saved uid, real gid, and saved gid to ucred, as well as the
  pcred->pc_uidinfo, which was associated with the real uid, only rename
  it to cr_ruidinfo so as not to conflict with cr_uidinfo, which
  corresponds to the effective uid.
o Remove p_cred from struct proc; add p_ucred to struct proc, replacing
  original macro that pointed.
  p->p_ucred to p->p_cred->pc_ucred.
o Universally update code so that it makes use of ucred instead of pcred,
  p->p_ucred instead of p->p_pcred, cr_ruidinfo instead of p_uidinfo,
  cr_{r,sv}{u,g}id instead of p_*, etc.
o Remove pcred0 and its initialization from init_main.c; initialize
  cr_ruidinfo there.
o Restruction many credential modification chunks to always crdup while
  we figure out locking and optimizations; generally speaking, this
  means moving to a structure like this:
        newcred = crdup(oldcred);
        ...
        p->p_ucred = newcred;
        crfree(oldcred);
  It's not race-free, but better than nothing.  There are also races
  in sys_process.c, all inter-process authorization, fork, exec, and
  exit.
o Remove sigio->sio_ruid since sigio->sio_ucred now contains the ruid;
  remove comments indicating that the old arrangement was a problem.
o Restructure exec1() a little to use newcred/oldcred arrangement, and
  use improved uid management primitives.
o Clean up exit1() so as to do less work in credential cleanup due to
  pcred removal.
o Clean up fork1() so as to do less work in credential cleanup and
  allocation.
o Clean up ktrcanset() to take into account changes, and move to using
  suser_xxx() instead of performing a direct uid==0 comparision.
o Improve commenting in various kern_prot.c credential modification
  calls to better document current behavior.  In a couple of places,
  current behavior is a little questionable and we need to check
  POSIX.1 to make sure it's "right".  More commenting work still
  remains to be done.
o Update credential management calls, such as crfree(), to take into
  account new ruidinfo reference.
o Modify or add the following uid and gid helper routines:
      change_euid()
      change_egid()
      change_ruid()
      change_rgid()
      change_svuid()
      change_svgid()
  In each case, the call now acts on a credential not a process, and as
  such no longer requires more complicated process locking/etc.  They
  now assume the caller will do any necessary allocation of an
  exclusive credential reference.  Each is commented to document its
  reference requirements.
o CANSIGIO() is simplified to require only credentials, not processes
  and pcreds.
o Remove lots of (p_pcred==NULL) checks.
o Add an XXX to authorization code in nfs_lock.c, since it's
  questionable, and needs to be considered carefully.
o Simplify posix4 authorization code to require only credentials, not
  processes and pcreds.  Note that this authorization, as well as
  CANSIGIO(), needs to be updated to use the p_cansignal() and
  p_cansched() centralized authorization routines, as they currently
  do not take into account some desirable restrictions that are handled
  by the centralized routines, as well as being inconsistent with other
  similar authorization instances.
o Update libkvm to take these changes into account.

ae3a37ad44 Adapt libkvm_getswapinfo() to make use of recently committed vm and swap
sysctls exporting swap information.  When running on a live kernel,
the sysctl's will now be used instead of kvm_read, allowing consumers of
this interface to run without privilege (setgid kmem).  Retain the
ability to run on coredumps, or on a kernel using kmem if explicitly
pointed at one.

A side effect of this change is that kvm_getswapinfo() is faster now in
the general case. If the SWIF_DUMP_TREE flag is given (pstat -ss does
this), the radix tree walker, which still uses kvm_read in any case, is
invoked, and therefore does require privilege.

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.

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)
