Patches for the OpenBSD base system are distributed as unified diffs.
|
|
Each patch is cryptographically signed with the
|
|
<a href="https://man.openbsd.org/OpenBSD-7.3/signify.1">signify(1)</a> tool and contains
|
|
usage instructions.
|
|
All the following patches are also available in one
|
|
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/7.3.tar.gz">tar.gz file</a>
|
|
for convenience.
|
|
|
|
<p>
|
|
Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
|
|
utility can be used to apply binary updates on the following architectures:
|
|
amd64, i386, arm64.
|
|
|
|
<p>
|
|
Patches for supported releases are also incorporated into the
|
|
<a href="stable.html">-stable branch</a>, which is maintained for one year
|
|
after release.
