09a50a4aae A variable had been unnecessarily assigned a bogus value because gcc was
"confused" about it being unassigned.  In fact, gcc was right.  Fix the
real problem by setting that variable before break-ing out of a select
statement so gcc is happy, and then remove the unnecessary assignment.

bd2ab5b7ea Rearrange all the error returns from sendfile() to make sure the original
input file and any temporary (filter) file are closed upon return, and
that is generally done at the end of the routine.  This should make it
easier for a later update (not yet written) to implement a "resend_copies"
option.

e0f2899581 Re-arrange how output filters (of=) are handled for queues going to
remote machines.  Now they really are handled *exactly* the same as
input filters (if=) for remote queues, except that they are started
with a different set of parameters.  This should fix a few subtle
bugs in output-filter processing on such queues.  It is a pretty
significant re-arranging of sendfile(), moving some of it to a new
execfilter() routine.

6737fb8eb7 Add another level of checking to 'chkprintcap', which is done by
"skimming thru" the printcap file looking for some common mistakes that
people make.  These are the kinds of mistakes where the printcap file
probably looks correct to human eyes, but is wrong in some subtle way
which causes a problem in some queue definitions.  The program treats
these as "warnings" not "errors".
    Note that I'm flexible on the m.f.c. schedule, if people would rather
this waited until after 4.5-release.

bae50f587d Move the checks for '/' a little sooner in the code which receives files
for a remote print job.  This change comes from OpenBSD (who got it from
Sebastian Krahmer of SuSE).  In OpenBSD this avoids a tiny theoretical
security issue, but that security issue does not exist in FreeBSD's lpr
due to the changes which added 'ctl_renametf()' just before 4.4-release.
This change is still worth doing in our version, but it isn't fixing a
security issue.

f06e6295c8 My recent changes to add the ctl_renametf routine assumed that print job
control-files will always start with 'cfA*'.  It turns out that some
implementations of lpd (such as solaris) may send a control file which
starts with 'cfB*', or really 'cf<anyLetter>*'.  Although such filenames
are very odd, we did used to accept them.  This changes ctl_renametf to
work correctly with them, and fixes up 'lpc clean' to match.

158a111b03 Change the recently-added 'o'-processing so it maps to 'l' instead of 'f'.
'l' ("plain text which includes control characters") is somewhat more
appropriate for 'o' ("postscript files"), and in fact some printers treat
'l' as a request to print a postscript file.

1053a31527 Basically rewrite the sortq() routine which is used by 'lpc clean' and
'lpc tclean'.  In some obscure cases, the previous version could cause a
valid user job to be removed (by 'clean'), due to invalid assumptions in
the sort routine.  This was a rare problem, unless ctlinfo.c is compiled
with 'LEAVE_TMPCF_FILES' turned on (to check what that rtn was doing).

ee2fdcd34f Add minimal support for "o"-type print-file actions in lpd control files.
This was described in the original RFC wrt lpr, but most lpr's do not
actually implement it.  There is some indication that MacOS 10.1 will
be using this when sending postscript files to print servers (that is
what "o"-type was supposed to signify -- postscript files).

2d01bec833 Change lpd to perform sanity and safety checks on control files as it
receives them from other hosts.  This is meant to protect from both
nefarious users (which maybe broke into some remote host that we accept
print jobs from), and broken implementations of lpr on other platforms.
This is done by changing recvjob.c to call the new ctl_renametf()
routine in the new common_source/ctlinfo.[ch] files.  This will not
affect jobs coming via lpr on the local machine.

a89ca1efdc Make 'lpc clean' somewhat safer. Add an 'lpc tclean' command, which allows
one to see what files would be removed *if* an 'lpc clean' is done.  'tclean'
will remove no files, and is therefore not a privileged command.  Also, both
'lpc clean' and 'lpc tclean' will now look for 'core' files in spool directories
(but not remove them).  They also print out an extra line of info when a
datafile to be removed is a symlink (from 'lpr -s'), saying what file it is
a symlink to.

The 'lpc clean' commands also now print out a summary line saying how many
queues were checked, how many files were removed (or "would be" removed, for
tclean), and how much disk space is involved.  For the benefit of those who
have many print queues, 'lpc clean all' will only print out the names of print
queues where some "interesting" files were found, instead of printing out a
header-line for every queue in your printcap file.

e066fac19f Add two new options for lpd: -c will log all connection-errors to syslog,
while -w allows connection from non-reserved ports.  Also improves the
helpfulness of various connection-error messages.

The changes for IPv6 added back in the reserved-port check which was mistakenly
dropped from lpd in 1997 (copying a change from openbsd).  It is best to have
that check in place, but the check breaks lpr's from some implementations of
lpr/lpd for Windows.  The -w option is for those admins who need to accept
jobs from non-reserved ports, the -c option is for admins who would like a
print-server machine to log all failed connection-attempts to syslog.

e402d6c915 Rename a few global variables which hold hostname-related values to be
more sensible/understandable.  'from'->'from_host'  'host'->'local_host'
'fromb'->'frombuf'  'fromhost'->'origin_host'  and a local-variable
named 'host'->'hostbuf'.  This fixes some compile-time warnings about
local variables shadowing global variables.

Other than renaming variables, the only actual code changes are to call
strlcpy() instead of strncpy() when setting those (renamed) variables,
and that 'from_ip' is now a strdup()-created buffer instead of being a
static buffer compiled in as 1025 bytes.
