Consensus between bde and pjd seemed to be that if the function names

type instead of being in front of the function name on the following

Move struct pidfh definition into pidfile.c, and leave a forward declaration
for pidfh in libutil.h in its place.
This allows us to hide the contents of the pidfh structure, and also
allowed removal of the "#ifdef _SYS_PARAM_H" guard from around the
pidfile_* function prototypes.
Modify pw_copy:
- if pw is NULL and oldpw is not NULL then the oldpw is deleted
- if pw->pw_name != oldpw->pw_name but pw->pw_uid == oldpw->pw_uid
then it renames the user
add new gr_* functions so now gr_util API is similar to pw_util API,
this allow to manipulate groups in a safe way.

- Commit work from libprocstat project. These patches add support for runtime
file and processes information retrieval from the running kernel via sysctl
in the form of new library, libprocstat. The library also supports KVM backend
for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have
been modified to take advantage of the library (as the bonus point the fstat(1)
utility no longer need superuser privileges to operate), and the procstat(1)
utility is now able to display information from memory dumps as well.
The newly introduced fuser(1) utility also uses this library and able to operate
via sysctl and kvm backends.
The library is by no means complete (e.g. KVM backend is missing vnode name
resolution routines, and there're no manpages for the library itself) so I
plan to improve it further. I'm commiting it so it will get wider exposure
and review.
We won't be able to MFC this work as it relies on changes in HEAD, which
was introduced some time ago, that break kernel ABI. OTOH we may be able
to merge the library with KVM backend if we really need it there.
Add two new system calls, setloginclass(2) and getloginclass(2). This makes
it possible for the kernel to track login class the process is assigned to,
which is required for RCTL. This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

Do not let pw.conf(5) or -M option affect creation of basehome, e.g., /home.
When the basehome does not exist, it creates all intermediate directories as
required, which is logically equivalent to mkdir(1) with -m and -p options.
However, it modifies all intermediate directories, not just the final home
directory unlike mkdir. This problem was introduced in two revisions, i.e.,
r1.59 (SVN r167919) and r1.60 (SVN r168044).

Simplify expand_number() by combining the (unrolled) loop with the

from int64_t to uint64_t; this makes it easier to check for overflow.

Remove login(3), logout(3) and logwtmp(3) from libutil.
These functions only apply to utmp(5). They cannot be kept intact when

cannot be used, since they provide a functionality which partially

It is believed the last subsystem that limited ID sizes to something
other than the current system-wide size (32-bits) has been updated so
for now just cautiously turn the check off. While here fix the check

Make the chpass Makefile honour NO_FSCHG.
The chpass Makefile tried to set the fschg flag on the binaries, even if
NO_FSCHG was passed to the installworld. This meant that if I installed
FreeBSD into a Jail, I couldn't installworld from within the Jail

Now that it listens to NO_FSCHG, we can just make it bail out when it
fails, just like PRECIOUSPROG does.
Revert (once again, and hopefully for the last time) to flock(2) locks.
The problem with fcntl(2) locks is that they are not inherited by child
processes. This breaks pidfile(3), where the common idiom is to open

Merge user/peter/kinfo branch as of r185547 into head.
This changes struct kinfo_filedesc and kinfo_vmentry such that they are
same on both 32 and 64 bit platforms like i386/amd64 and won't require
sysctl wrapping.
Two new OIDs are assigned. The old ones are available under
COMPAT_FREEBSD7 - but it isn't that simple. The superceded interface
was never actually released on 7.x.
The other main change is to pack the data passed to userland via the
sysctl. kf_structsize and kve_structsize are reduced for the copyout.
If you have a process with 100,000+ sockets open, the unpacked records
require a 132MB+ copyout. With packing, it is "only" ~35MB. (Still
seriously unpleasant, but not quite as devastating). A similar problem
exists for the vmentry structure - have lots and lots of shared libraries
and small mmaps and its copyout gets expensive too.
My immediate problem is valgrind. It traditionally achieves this
functionality by parsing procfs output, in a packed format. Secondly, when
tracing 32 bit binaries on amd64 under valgrind, it uses a cross compiled
32 bit binary which ran directly into the differing data structures in 32
vs 64 bit mode. (valgrind uses this to track file descriptor operations
and this therefore affected every single 32 bit binary)
I've added two utility functions to libutil to unpack the structures into
a fixed record length and to make it a little more convenient to use.
