To: Buildroot List; +Cc: Thomas Petazzoni, Nicolas Carrier
In commit 13fc9dcb34926e9b6310b23662920c55c96d83a1, netsnmp was bumped
from 5.9.3 to 5.9.4 to fix two CVEs.
However, even though it's a minor version bump, there are actually 163
commits upstream between those two minor releases, and some of them
are breaking existing use-cases. In particular upstream
a2cb167514ac0c7e1b04e8f151e0b015501362e0 now requires that config_()
macros in MIB files are terminated with a semicolon, causing a build
breakage with existing MIB files that were totally valid with 5.9.3.
This commit therefore proposes to revert back to 5.9.3, by reverting
those two commits:
56caafceab3ec12669ccb7aa6fc8b653778064e1 package/netsnmp: fix musl build
13fc9dcb34926e9b6310b23662920c55c96d83a1 package/netsnmp: security bump to version 5.9.4
and instead revert the one upstream commit that fixes both CVEs.

Note: for master, we probably want to keep the bump to 5.9.4, as it's
upstream decision. This commit is really intended for
2023.02.x (perhaps other maintenance branches), where we don't want to
break things for users.

I saw that comment a bit too late, and pushed to master.
However, after reasing the CHANGES file, I noticed that:
IMPORTANT: SNMP over TLS and/or DTLS are not functioning properly
in this release with various versions of OpenSSL and will be fixed
in a future release.
So, it was anyway a good idea to revert (pfeew...)
