[patch] security(8) and spamd blacklist
Hi, security(8) iterates over /var/mail and check is the files belong to the owner of the same name. So far so good, but spamd.conf.5 says: override:\ :white:\ :method=file:\ :file=/var/mail/override.txt: myblack:\ :black:\ :msg=/var/mail/myblackmsg.txt:\ :method=file:\ :file=/var/mail/myblack.txt: so the user *black.txt* and/or *override.txt* are assumed to exist by security(8). As it says: Checking mailbox ownership. user myblack.txt mailbox is owned by _spamd The following diff documents this in the manpage of spamd.conf(5) by changing the path to /var/mail/_spamd/. I thought about changing security(8) to fix this, but _spamd is the name of the user, so it does whats it's supposed to do. Comments? Because the notification above is very annoying. --f.

The default value is 1 and if -#0 is called, this default value is used.
Disallow -#0 silently makes this default value useless. And other
BSD versions of lpr(1) uses this default value:
https://svnweb.freebsd.org/base/head/usr.sbin/lpr/lpr/lpr.c?revision=275855=co
http://gitweb.dragonflybsd.org/dragonfly.git/blob_plain/HEAD:/usr.sbin/lpr/lpr/lpr.c
http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/src/usr.sbin/lpr/lpr/lpr.c?rev=1.46=text/plain_with_tag=MAIN
So I think this behavior should not be changed. The above versions redirect
negative values to 1 as well,
but calling -#-1 looks wrong (what should lpr(1) print, if -1 copies are
requested), so I think starting from
0 is okay.

> I might be missing something, but why silently allow -#0 ?
The default value is 1 and if -#0 is called, this default value is used.
Disallow -#0 silently makes this default value useless. And other
BSD versions of lpr(1) uses this default value:
https://svnweb.freebsd.org/base/head/usr.sbin/lpr/lpr/lpr.c?revision=275855=co
http://gitweb.dragonflybsd.org/dragonfly.git/blob_plain/HEAD:/usr.sbin/lpr/lpr/lpr.c
http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/src/usr.sbin/lpr/lpr/lpr.c?rev=1.46=text/plain_with_tag=MAIN
So I think this behavior should not be changed. The above versions redirect
negative values to 1 as well,
but calling -#-1 looks wrong (what should lpr(1) print, if -1 copies are
requested), so I think starting from
0 is okay.

[patch] lpr style
Hi,
this diff changes the following:
- exit(3) to return at the end of main functions
- use /* NOTREACHED */ were it belongs according to style(9)
- lpc.c and lpd.c lack a return at the end of the main functions, as the main
loops exists the
program. I'm not sure if this is a "coders choise" argument, so correct me if
I'm wrong.

[patch] lpr atoi -> strtonum
Hi,
change atoi(3) -> strtonum(3) in lpr(1) and lprm(1).
lprm(1) avoids negative numbers to be the first argument by using getopt(3),
but supported values like 2.2.

Personally, I would recommend that xstrdup just calls strdup(3), as
Theo said: it's 100.00% portable.
But I don't think I'm the right person who should answer that question. ;)

How portable is strdup? strdup is extremely portable. The last mainstream operating system which lacked it was Ultrix. So you could call it 100.00% portable. Since there is no portable version of openRCS is it that necessary to focus on portability? Functions like explicit_bzero(3) are not portable either, but used widely. Or is it more to find a balance between the usage of internal function, but make the tool not that hard to port to other systems? Regards, --F.

Use err() instead of errx(), so errno will be printed additionally.

[patch]rcs: usage functions above the main ones
Hi tech@,
most of the tools implements the *usage* function above the *main* function.
This patch makes it more consistent to these tools and where the different

functions are implemented in rcs in general.
Any comments?

Could some verify that I didn't miss a test case.
Hmm, your examples show no diffference. I think the intention is to
not change the behaviour, right?
Yes.
But as Tobias mentioned the behaviour will change anyway using my diff.
I'm checking out the official GnuRCS version regarding this right now.

[Patch]rcs: use rcsnum_cmp
Hi tech,
like the XXX comment says, rcsnum_cmp() can be used instead of a *for* loop.
The following shows the original behavior:
$ co -r1.2 foo.txt,v
foo.txt,v -- foo.txt
revision 1.2
done
$ co -r1.1 foo.txt,v
foo.txt,v -- foo.txt
revision 1.1
done
$ co foo.txt,v
foo.txt,v -- foo.txt
revision 1.2
done
The following shows the changed behavior:
$ co -r1.2 foo.txt,v
foo.txt,v -- foo.txt
revision 1.2
done
$ co -r1.1 foo.txt,v
foo.txt,v -- foo.txt
revision 1.1
done
$ co foo.txt,v
foo.txt,v -- foo.txt
revision 1.2
done
Could some verify that I didn't miss a test case.

Hi tech,
the OpenRCS rcs command produces the following output if -l and
-u is
used in the same command:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
I've looked at GnuRCS and it has another way to handle these
parameters
(it seems the other BSDs use GnuRCS, too).
Debian 7.5:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
rcs: foo.txt,v: no lock set on revision 1.1
1.1 locked
$ rcs -u1.1 -l1.1 foo.txt
Segmentation fault
Well, I think the Segmentation fault isn't that important :),
but GnuRCS
does not lock and unlock a file by using the same command like
OpenRCS.
I think the different implementations of RCS should share the
same
behaviour:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
done
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 unlocked
done

[patch]lock and unlock like GnuRCS
Hi tech,
the OpenRCS rcs command produces the following output if -l and -u is
used in the same command:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
I've looked at GnuRCS and it has another way to handle these parameters
(it seems the other BSDs use GnuRCS, too).
Debian 7.5:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
rcs: foo.txt,v: no lock set on revision 1.1
1.1 locked
$ rcs -u1.1 -l1.1 foo.txt
Segmentation fault
Well, I think the Segmentation fault isn't that important :), but GnuRCS
does not lock and unlock a file by using the same command like OpenRCS.
I think the different implementations of RCS should share the same
behaviour:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
done
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 unlocked
done

One concern: atoi() does not mind trailing stuff, while strtonum()
does. Did you verify that the strings are just numbers in all cases?
according to the code and the manpages there are two different methods
available to specify the timezone.
- LT
- +-hh:mm
LT is handled seperatly and the code below - atoi(3) - only converts the hour
and
minute string values after seperation into int, e.g. +09:88 - h = 09; m = 88.
The + or - sign will be handled in a different part of the code.
I think this diff won't change functionality.

Half true. :)
The behavior is intended. I don't really know why they care about
freeing null, but the intention is clearly to check for it; otherwise
they would just call free() in the first place. (actually, i think the
rationale is that to assure portability, you need a strict version of
free that matches the broken version found elsewhere or you will
accidentally do something not portable. under that assumption, and
assuming we don't care about those platforms, the correct fix is to
delete xfree entirely.)
The X option, though, to malloc.conf doesn't check NULL to free. It
just makes malloc abort instead of returning null. I don't think it's
a useful option either way. Don't use it.
Based on Teds suggestion, this diff deletes xfree() entirely.

[PATCH] rcs: don't use lock and unlock in the same command
Hi tech,
the OpenRCS rcs command produces the following output if -l and -u is used in
the
same command:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
1.1 unlocked
I've looked at GnuRCS and it has another way to handle these parameters (it
seems the other BSDs
use GnuRCS, too).
Debian 7.5:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
rcs: foo.txt,v: no lock set on revision 1.1
1.1 locked
$ rcs -u1.1 -l1.1 foo.txt
Segmentation fault
Well, I think the Segmentation fault isn't that important, but GnuRCS does
not lock and unlock
a file by using the same command like OpenRCS.
I think the different implementations of RCS should share the same behaviour,
so I changed OpenRCS:
$ rcs -l1.1 -u1.1 foo.txt
RCS file: foo.txt,v
1.1 locked
done
$ rcs -u1.1 -l1.1 foo.txt
RCS file: foo.txt,v
1.1 unlocked
done

Re: [PATCH]unused NULL check before calling free
On Fri, Aug 01, 2014 at 08:03:58AM -0400, Ted Unangst wrote:
Half true. :)
The behavior is intended. I don't really know why they care about
freeing null, but the intention is clearly to check for it; otherwise
they would just call free() in the first place. (actually, i think the
rationale is that to assure portability, you need a strict version of
free that matches the broken version found elsewhere or you will
accidentally do something not portable. under that assumption, and
assuming we don't care about those platforms, the correct fix is to
delete xfree entirely.)
The X option, though, to malloc.conf doesn't check NULL to free. It
just makes malloc abort instead of returning null. I don't think it's
a useful option either way. Don't use it.
Based on Teds suggestion, this diff deletes xfree() entirely.

Going by this context, a quick grep in src/usr.bin/rcs, and
especially the error message, the NULL check's purpose is to
catach this condition.
The code you claim to correct:
there is an unnecessary NULL check before calling free.
would have been of the form:
if (ptr != NULL)-or-if (ptr == NULL)
free(ptr); return;
That is true, but free() can handle NULL itself:
...
/* This is legal. */
if (ptr == NULL)
return;
That's why there is no need, to use a condition like:
if(ptr == NULL)
errx(1, xfree: NULL pointer given as argument);

For educational purpose i guess humanity need a free(NULL) is valid T shirt,
i learned it in the mailing list around a year ago.
Maybe the back would be if not, patch your OS, or better use OpenBSD
That would be very cool!

This would break on 64 bits archs: there, SIZE_MAX casted to an off_t
is -1 (implementation-defined behavior iirc).
Also it breaks platforms with 32 bits off_t (this does not affect

that does not do assumptions about the site of off_t and size_t could

[PATCH] rcs void casts
Hi tech,
there are a few void casts in rcs. But I have a question about that.
Are these casts really necessary? I've read that the compiler warns, because of
unused variables.
But no compiler warnings about that on amd64.
That's why I just added this small diff, in order to get feedback if the casts
are necessary or not.

No, they are not necessary.

Usually, you don't choose your style to please static analysis tools -
there are too many of them, of too varying quality and signal-to-noise
ratio, to please them all.
Rather, it makes sense to tune static analysis tools, including
compilers, to warn about dangerous style, but to not warn about style
that is merely a matter of taste.
That said, for functions that usually require checking of return
values, the void cast can be used to indicate this call was audited,
and ignoring the return value is considered safe, either because
this specific call cannot actually fail, or because failure does
not need explicit handling at this point. Typical functions where
this makes sense are snprintf(3), strlcpy(3), strlcat(3). So i
clearly wouldn't remove the cast from strftime() unless you have
reason to assume that no proper audit was done, or this is broken
and needs fixing. In this case, the buffer is large enough, so
the cast should stay.
On the other hand, on functions that hardly ever require checking
the return code, casting to void is pointless, so i tend to
remove such casts when editing nearby code. A typical example
is (void)close(fd); which is rarely more helpful than
just close(fd);.
In this case, the rcsnum_tostr() return value can't be used for error
checking in the first place, that function calls errx(3) on failure,
so when editing nearby code, i'd probably remove that cast. But it
doesn't warrant a commit on it's own imho.
Yours,
Ingo
I see, thank you for the explanations.
It was just for me to make it clear when (void) is used.
