526b145c23 Never allow a user to use crontab if opening /var/cron/{allow,deny} fails
for any reason other than ENOENT (think resource limits). Close allow and
deny files before allowed() returns to stop the user's EDITOR being able to
read them.

bb817201ed load_env(), the function that attempts to parse a crontab
line as an environment variable assignment, is broken
and not conformant to its description in the manual page.

I think it is worthwhile to have that fix in 4.6.

the patch Matthew submitted, but I broke the lines in a more FreeBSD

5d3e1fcab1 free_entry(): Don't free e->envp if it's already NULL; likewise for
e->cmd.  free_entry() now does the right thing with
partially-initialized structures.

load_entry(): Don't call env_free() on e->envp throughout the routine
before jumping to eof; the free_entry() call at that label will take
care of it.  The previous behavior resulted in e->envp being free'd
twice (well, the second time would usually result in a crash, but
that's besides the point); once in load_entry(), and once in
free_entry() after the former called the latter.  Also note that the
check added to free_entry() (above) doesn't help, since e->envp wasn't
reset to NULL after env_free().

Otherwise, "crontab -l > file; vi file; crontab file" adds an extra set

be821963c1 Made the special handling of the daylight time switches optional,
enabled by the option "-s" (for dSt). This returned the default behavior
to its original form.

The new option name is not "-d" because that would cause associations with
"debug" and cron already has "-x" for debugging, so this would cause
confusion.

25e9ca2b19 Attempt to fix problem with users being able to convince the crontab
program to read any file which is a valid crontab file.

The fix is based on that used in NetBSD and OpenBSD - we keep the
file open while the user is editing it. This means that files must
be edited in place. Cron attempts to warn you if your editor does
not do this. The fact that the file must be edited in place is also
noted in the man page.

This patch has been confirmed to work by atleast one person on
-security and has been tested locally.
