Since 2021-01-31, lint no longer requires a CONSTCOND comment in a
do-while-0 statement since this is a common code pattern, especially in
statement-like macros.
Remove const from the 2nd argument.
const char ** and char ** are incompatible types and it was a cost to keep
the technically incompatible form for a more purist variation. NetBSD was
almost the last alive OS to still keep the const argument (known leftovers:
Minix and Illumos).
Keep the const form for the internal purposes inside citrus and rump.
Address the build breakage fallout in the same change.
There are no ABI changes.
Change accepted by core@.
GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)
use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."
mail's execute() needs a volatile for setjmp().
telnet has a missing {} issue.
isdnd's print_config() has a missing/wrong {} issue, and
its p_q931bc() has inconsistent indentation (but not any
actual problem.)
map-mbone's accept_neighbors2() compares a vs. a instead
of a vs. b.
sysinst's pm_cgd_check() has missing {} issue.
timed's main() has missing {} issue.
0001. Do not recognize paths, mail folders, and pipes in mail addresses
by default. That avoids a direct command injection with syntactically
valid email addresses starting with |.
Such addresses can be specified both on the command line, the mail
headers (with -t) or in address lines copied over from previous
while replying.
This was assigned CVE-2014-7844 for some versions of BSD mailx. It is
documented behavior for Heirloom mailx, and was mentioned in an old
technical report about BSD mailx (which does not usually make its way
into operating system installations). The patch switches off this
processing and updates the documentation.
Added expandaddr option to explicitly enable this behavior.
0002. When invoking sendmail, prevent option processing for email
address arguments. This prevents changing e.g. the Postfix
configuration file in unexpected ways. This behavior was documented for
BSD mailx (sort of), but not for Heirloom mailx. We did not assign a
CVE to this because it is more of a missing feature, and code invoking
mailx needs adjustment in the caller as well.
Fixed.
0003. Make wordexp support mandatory. (No functional change.)
Fixed (replaced explicit shell pipe implementation).
0004. Prevent command execution in the expand function, which is IMHO
unexpected. (Not really required with patch 1, and there is still
information disclosure/DoS potential if this expansion occurs.) This is
a historic vulnerability already fixed in the Debian package,
retroactively assigned CVE-2004-2771:
Fixed (as part of the pipe replacement with wordexp).
Move all the reference manuals to subdirs of /usr/share/doc/reference.
We have subdirs ref1-ref9, corresponding to man page sections 1-9.
Everything that's the reference manual for a program (sections 1, 6,
8), C interface (sections 2, 3), driver or file system (section 4),
format or configuration (section 5), or kernel internal interface
(section 9) belongs in here.
Section 7 is a little less clear: some things that might go in section
7 if they were a man page aren't really reference manuals. So I'm only
putting things in reference section 7 that are (to me) clearly
reference material, rather than e.g. tutorials, guides, FAQs, etc.
This obviously leaves some room for debate, especially without first
editing the docs with this distinction in mind, but if people hate
what I've done things can always be moved again.
Note also that while roff macro man pages traditionally go in section
7, I have put all the roff documentation (macros, tools, etc.) in one
place in reference/ref1/roff. This will make it easier to find and
also easier to edit it into some kind of coherent form.
Update the <bsd.doc.mk> infrastructure, and update the docs to match
the new infrastructure.
- Build and install text, ps, pdf, and/or html, not roff sources.
- Don't wire the chapter numbers into the build system, or use them in
the installed pathnames. This didn't matter much when the docs were a
museum, but now that we're theoretically going to start maintaining
them again, we're going to add and remove documents periodically and
having the chapter numbers baked in creates a lot of thrashing for no
purpose.
- Specify the document name explicitly, rather than implicitly in a
path. Use this name (instead of other random strings) as the name
of the installed files.
- Specify the document section, which is the subdirectory of
/usr/share/doc to install into.
- Allow multiple subdocuments. (That is, multiple documents in one
output directory.)
- Enumerate the .png files groff emits along with html so they can be
installed.
- Remove assorted hand-rolled rules for running roff and roff widgetry
and add enough variable settings to make these unnecessary. This
includes support for
- explicit use of soelim
- refer
- tbl
- pic
- eqn
- Forcibly apply at least minimal amounts of sanity to certain
autogenerated roff files.
- Don't exclude USD.doc, SMM.doc, and PSD.doc directories from the
build, as they now actually do stuff.
Note: currently we can't generate pdf. This turns out to be a
nontrivial problem with no immediate solution forthcoming. So for now,
as a workaround, install compressed .ps as the printable form.
