4d5e876be3 use pwrite to always write at the begining of the file.. If multiple calls 
to pidfile_write happen, the pidfile will have nul characters prepended
due to the cached file descriptor offset...

560c4fc142 - Add a note that passing NULL to pidfile_write(), pidfile_remove() and 
pidfile_close() functions is safe. This possibility is used in example code.
- Cast pid_t to int.

ba183db70c Replace strncpy() with strlcpy() when parsing login time limit strings 
from /etc/login.conf, or an unterminated string buffer could result.
Probably, login_times.c should reject excessively long time strings as
unparseable, rather than truncating, which might render an invalid
string valid.

This function removes all environment variables except
the ones listed on a "whitelist."

The function accepts two whitelist arguments.
If the first is NULL, a built-in default list will be
used.  This allows callers to get a variety of behaviors:
  * Default screening: provide NULL for both lists
  * Custom screening: provide a custom list for the first argument
  * Modified default screening: provide NULL for first arg,
     list of additional variables to preserve in the second arg

Dag-Erling Smørgrav
324e8fd88f Fix for the sshd(8) utmp problem. Previously, login(3) would ignore the tty 
named by its argument and use ttyslot(3) instead to determine what slot to
use.  The problem is that sshd(8) calls pam_open_session(3) before forking
the child (as it should), at which point it does not have a controlling
terminal.  Also, ttyslot(3) is very crude as it assumes fd 0, 1 or 2 refers
to the controlling terminal, which is usually (but not always) the case.

Instead of using ttyslot(3) to determine the slot number, look up the
specified tty in /etc/ttys ourselves (this is what ttyslot(3) does anyway).
