Otto Moerbeek (otto@), the author of OpenBSD's malloc(3) implementation, has comitted another great feature - backtraces for leak detection:

CVSROOT:	/cvs
Module name:	src
Changes by:	otto@cvs.openbsd.org	2023/12/04 00:01:45

Modified files:
	lib/libc/stdlib: malloc.3 malloc.c 

Log message:
Save backtraces to show in leak dump. Depth of backtrace set by
malloc option D (aka 1), 2, 3 or 4.  No performance impact if not
used.  ok asou@

Otto's original message to tech@ includes an example use of the feature.

Tobias Heider (tobhe@) has announced the release of version 7.3 of OpenIKED:

We have released OpenIKED 7.3, which will be arriving in the OpenIKED
directory of your local OpenBSD mirror soon.

Omar Polo (op@) has announced the release of version 7.4.0p1 of OpenSMTPD.

It is a bugfix release.

In a long series of commits, Robert Nagy (robert@) updated clang(1)/llvm in -current to version 16:

Naturally, this has involved supporting work elsewhere in base, and in ports.

A new stable release of LibreSSL is out, and should be arriving on a mirror near you shortly.

Brent Cook (bcook@)'s announcement reads:

We have released LibreSSL 3.8.2, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. This is the
first stable release for the 3.8.x branch, also available with OpenBSD 7.4

Theo de Raadt (deraadt@) posted to tech@ a message entitled disruptive amd64 snapshot coming. It reads:

There is a pretty disruptive amd64 snapshot coming, so anyone who is
using snapshots for critical stuff should take a pause.  (This warning
about a development step is unusual, I won't make it common practice).

Of course, on non-critical amd64 systems running snapshots, this is a good opportunity to test (and report any problems).

Hot on the heels of the release of OpenBSD 7.4, Omar Polo (op@) has announced the release of OpenSMTPD 7.4.0p0. The announcement reads,

Subject:    OpenSMTPD 7.4.0p0 Released
From:       Omar Polo <op () openbsd ! org>
Date:       2023-10-25 7:33:43


OpenSMTPD is a FREE implementation of the SMTP protocol with some common
extensions. It allows ordinary machines to exchange e-mails with systems
speaking the SMTP protocol. It implements a fairly large part of RFC5321
and can already cover a large range of use-cases.

It runs on OpenBSD, NetBSD, FreeBSD, DragonFlyBSD, Linux and OSX.

The archives are now available from the main site at www.OpenSMTPD.org

As announced on the misc@ mailing list, Otto Moerbeek (otto@), the author of OpenBSD's malloc(3) implementation [a.k.a. "otto malloc"], has written a tutorial on the new malloc(3) leak detection available in OpenBSD 7.4

Read it at: OpenBSD's built-in memory leak detection

Since the publication of that write-up, Otto has committed further enhancements:

CVSROOT:	/cvs
Module name:	src
Changes by:	otto@cvs.openbsd.org	2023/10/22 06:19:26

Modified files:
	lib/libc/stdlib: malloc.3 malloc.c 

Log message:
When option D is active, store callers for all chunks; this avoids
the 0x0 call sites for leak reports. Also display more info on
detected write of free chunks: print the info about where the chunk
was allocated, and for the preceding chunk as well.
