[thaJeztah]

• backport of vendor: github.com/ishidawataru/sctp v0.0.0-20230406120618-7ff4192f6ff2 #45301
• addresses Flaky test: libnetwork TestSCTP4Proxy (broken on s390x?) #42495

⚠️ Minor conflict (adjacent lines) in vendor.mod and vendor.sum, due to these
commits not (yet) being in this branch;

• bc1dec7 (vendor: assorted vendor updates for containerd 1.7.0 #45158)
• b98c05d (vendor: assorted vendor updates for containerd 1.7.0 #45158)

We might still consider cherry-picking those, but we can probably do so separately (and fix the minor conflicts for that)

---

• Prevent from descriptor leak
• Fixes optlen in getsockopt() for s390x

LGTM; agreed on the order of operations re: containerd 1.7

[thaJeztah]

Yes, I definitely wouldn't want to backport all of that other PR (not containerd 1.7; 1.6 is LTS and fine to use), but there's some other dependencies that might be good to update.

Backporting those would only cause conflicts in vendor.mod / vendor.sum (or vendor/modules.txt) so trivial to resolve (and not really worth mentioning in most cases), so not too concerned about that.
