Author: Wolfgang Breyha
Bugzilla: 935
Attachment: 378
(looks like it could do with a strcmp check at the end before the extra
string_copy, but that's a nicety and the author has presumably been
running with this).

It appears some make(1)s are not complaining about variables defined
with leading whitespace on the line. Permit that where we can, for the
lookups, but it's not tenable for CFLAGS_DYNAMIC.
Some people are specifying knobs on the make command-line, so we get
them via the environment.
Tested: indented LOOKUP_CDB and commented out LOOKUP_DNSDB, supplying it
via { make LOOKUP_DNSDB=yes }. { exim -d --version } shows both are
built-in, no results from { fgrep DNSDB build-*/Makefile }.

Update valgrind.h and memcheck.h to copies from valgrind-3.6.0.
This fixes portability to compilers other than gcc, notably
Solaris CC and HP-UX CC.
Fixes: bug #1050.

Fixes bug #1073

Should not code at 9am when still awake then.
Should sanity-review such code changes before submitting (after sleep).
Should s,/usr/xpg4/bin/sh,/bin/bash, as a convenient test to confirm
what I suspected. But should do so pre-submit.
Doh.

Don't abort if CFLAGS_DYNAMIC not defined. Oops!
Attempt to get a POSIX environment on Solaris.
Document POSIXy assumptions going forward.
Problems reported by: Dennis Davis

The new code was calling DEBUG(<n>) for values of n including 4, 5, 9;
that was an Exim 3 API, we now use bits; -v sets bit 0x1, -bP implies
-v, so { exim -bP } was pulling up random debug messages.
Switched all the DEBUG checks to be DEBUG(D_lookup).
|
|
If dropping privileges for untrusted macros, we disabled normal logging
on the basis that it would fail; for the Exim run-time user, this is not
the case, and it resulted in successful deliveries going unlogged.
Fixed. Reported by Andreas Metzler.

When invoked { exim -d -bV } show these build-time options that affect
what can be done.

DCC return codes were not always correct. Patch from DCC code
maintainer, Wolfgang Breyha.

Spec: both doc date and release date (plus copyright year).
Filter: only release date (doc not changed, so neither is copyright year)
|

I assume stdint.h and intptr_t available for any platform where we're
running the test suite.
|
|
If we've *dropped* privilege, it's okay to not abort if setgid fails.
Document some of what's now needed for the test suite.
Adjust the test suide for better post-4.73 compat.
|
|
Docs deliberately keep changebars since v4.72 as 4.73 has not been out
for long.
OptionLists updates for dynamic modules and for the security changes
from 4.73.
|

I forgot about README.UPDATING and introduced a new txt file with the
4.73 release, noting incompatible changes. Because these weren't
documented in the normal place, some people missed them. Mea culpa.
Integrated the notes from IncompatibleChanges into README.UPDATING.
Added a note on the ABI of the dynlookups.

CVE-2011-0017
One assertion of the unimportance of checking the return value was wrong,
in the event of a compromised exim run-time user.

Debug version display reports library info.
Bumps lookup API magic constant, adds new field to module API.
When invoking { exim -d -bV } we can display more version information.
Show versions for many external libraries, including both compile-time
and run-time information if we can.
Optional for modules, may be NULL. Implemented for MySQL, SQLite &
Whoson lookups. For all lookups, if dynamically loaded, report the
Exim version number from the build. (Packagers will bundle stuff, but
dynamic modules are no longer just available for packagers, so we need
to deal with less managed environments and people forgetting to install
new modules).
Suggest in EDITME that users of modules not using package management
consider embedding a version number in the path to the modules.
Should consider removing the TLS (OpenSSL/GnuTLS) reporting from the
default -bV display and moving it into the debug display. Not done.
Created version.h, now support a version extension string for
distributors who patch heavily. Henceforth release engineer should
change the version in version.h not version.c.

(1) Commit eec525c43adade97ff94d839810faf7cb35bd87f broke module
support, because we *do* still need some exported variable
definitions, as for a module to actually work, we need the
per-module _INCLUDE/_LIBS settings.
(2) FreeBSD's nsdispatch() will leave dlerror() returning a complaint
about "_nss_cache_cycle_prevention_function"; we need to clear the
error state before the dlsym() call, so that any error found
afterwards must have come from that dlsym() call. Fix is just an
extra call to dlerror(), which should be portable.
I can now use sqlite3 from a module, in FreeBSD.

It can be used for individual user certs but is really intended for
CAs. Note this, and explain that if the tls_verify_certificates value
is a file, then the certs within are sent from the server to clients,
thus is public data.

The 4.73 fixes were a little too stringent and complained about the
permissions on /dev/null. Exempt it from some checks.
Reported by Andreas M. Kirchwitz

When writing the patch, originally nothing other than a cp was needed if
there were no dynamic modules. That changed, but the guard at the top
did not. Remove that check.
bash does not like a block which consists solely of a comment. Provide
a ':' invocation.
Both problems spotted by Simon Arlott -- thanks.

Document the dynamic lookup module capability in spec.xfpt.
Include a ChangeLog item.
Avoid the GNU-specific "export" make(1) directive.
Build the lookups Makefile using the existing framework.
Build with BSD Make once more.
The src/lookups/Makefile that is used at build time now has the dynamic
content come from scripts/lookups-Makefile.
Add CFLAGS_DYNAMIC support, which can be set in Local/Makefile.
Provide defaults for Linux & FreeBSD.
Ensure that build fails early if a dynamic module is requested but
CFLAGS_DYNAMIC is not defined.

This is really rather crude... but should work.
