POSIX 2008 and XSI 7require strcoll() for opendir() is not true.
I can't find such requirement in POSIX 2008 and XSI 7.
So, back out that part of my commit, returning old strcmp(), and remove
this misleading comment.
By using random values for ut_id, not based on the TTY name, it is
possible to run for example login(1) multiple times on the same TTY,
without overwriting any previous records.
The output of w(1) will then be as follows:
| 12:26PM up 2 days, 2:31, 5 users, load averages: 0.01, 0.03, 0.03
| USER TTY FROM LOGIN@ IDLE WHAT
| ed pts/2 mekker.80386.nl 12:26PM - w
| root pts/2 - 12:26PM - w
| root pts/2 - 12:26PM - w
| root pts/2 - 12:26PM - w

It also matches now how our 'ls' works for years.
b) Remove comment expressed 2 fears:
1) One just simple describe how strcoll() works in _any_ context,
not for directories only. Are we plan to remove strcoll() from everything
just because it is little more complex than strcmp()? I doubt, and
directories give nothing different here. Moreover, strcoll() used
in 'ls' for years and nobody complaints yet.
2) Plain wrong statement about undefined strcoll() behaviour. strcoll()
always gives predictable results, falling back to strcmp() on any
trouble, see strcoll(3).
No objections from -current list discussion.

- Massively reduce BSS usage. Let futx_to_utx() dynamically allocate the
structure. There is only a very small amount of applications out there
that needs to use the utmpx database. Wasting 1 KB on unused
structures makes little sense.
- Just let getutxid() search for matching ut_id's for any *PROCESS-type.
This makes the code a bit more future-proof.
- Fix a POSIX-mistake: when reading POSIX and the OpenSolaris
implementation, getutxline() must return USER_PROCESS and
LOGIN_PROCESS records whose ut_lines match. When reading POSIX, it
seems LOGIN_PROCESS should not use ut_line at the first place. I have
reported this issue.
reference count, and decrements it on dereference. If referenced object
is deallocated, object type is reset to OBJT_DEAD. Consequently, all
vnode references that are owned by object references are never released.
vunref() the vnode in vm object deallocation code for OBJT_VNODE
appropriate number of times to prevent leak.
Add an assertion to the vm_pageout() to make sure that we never get
reference on the vnode but then do not execute code to release it.

freed the inpcb, it was possible to not set the
proper flags on the pcb (i.e. the socket is not there).
This is HIGHLY unlikely since no one else should be
able to find the socket.. but for consistency we
do the proper loop thing to make sure that we
mark the socket as gone on the PCB.
I changed login_tty() to only work when the application is not a session
leader yet. This works fine for applications in the base system, but it
turns out various applications call this function after daemonizing,
which means they already use their own session.
If setsid() fails, just call tcsetsid() on the current session.
tcsetsid() will already perform proper security checks.

After comparing how other systems deal with utmp/utmpx, I noticed many
systems don't even care about ttyslot(3) anymore, since utmpx doesn't
use TTY slots anyway. We don't provide any tools to access old utmp
files anymore, so there is no use in letting applications write to a
proper offset within the utmp file.
Just let ttyslot(3) always return 0, which seems to be the default
behaviour on operating systems like Linux as well.
whether to use source address selection (default) or the primary
jail address for unbound outgoing connections.
This is intended to be used by people upgrading from single-IP
jails to multi-IP jails but not having to change firewall rules,
application ACLs, ... but to force their connections (unless
otherwise changed) to the primry jail IP they had been used for
years, as well as for people prefering to implement similar policies.
Note that for IPv6, if configured incorrectly, this might lead to
scope violations, which single-IPv6 jails could as well, as by the
design of jails. [1]
