QCLINUX: arm64: configs: qcom: Enable XDP sockets (AF_XDP)

[Raj (raj-patel412)]

Enable CONFIG_XDP_SOCKETS to support AF_XDP zero-copy networking on Qualcomm platforms. AF_XDP provides a high-performance path for packet processing by allowing XDP programs to redirect frames directly to userspace via shared memory rings, bypassing the normal kernel network stack.

❌ check-patch-compliance

Root cause: The commit uses QCLINUX: prefix, which is not in the checker's allowed list.

Failure details:

Checking commit: QCLINUX: arm64: configs: qcom: Enable XDP sockets (AF_XDP)
Commit summary does not start with a required prefix

Analysis:

This is a known limitation of the check-patch-compliance checker. The checker only accepts these prefixes:

• FROMLIST: (posted to mailing list)
• FROMGIT: (from maintainer tree)
• UPSTREAM: (merged into mainline)
• BACKPORT: (backported with modifications)

However, QCLINUX: is a valid vendor-internal prefix used for Qualcomm-specific changes that have no upstream equivalent. This commit is a vendor-only config change enabling CONFIG_XDP_SOCKETS in the Qualcomm config fragment.

Why this happens:

The check-patch-compliance checker enforces upstream-linkable prefixes and requires a Link: tag pointing to lore.kernel.org. For vendor-only changes like this config addition, there is no upstream link because:

1. This is a Qualcomm-specific config fragment (arch/arm64/configs/qcom.config)
2. The change is not posted upstream
3. No upstream equivalent exists

Options:

1. Accept the failure (Recommended for this case)

   • This is a known checker limitation for vendor-only commits
   • The commit is properly formatted with QCLINUX: prefix
   • The commit has proper Signed-off-by: trailer
   • The change is legitimate (enabling XDP sockets support)

2. Change prefix to FROMLIST: + add fake Link (Not recommended)

   • Would require posting the patch upstream first
   • Config fragments are typically not upstreamed
   • Would be misleading

3. Remove prefix entirely (Not recommended)

   • Would fail tag-check (mandatory for qcom-6.18.y branch)
   • All commits to non-qcom-next/qcom-next-staging branches require a prefix

Reproduce locally:

cd kernel
bash ../kernel-checkers/check-patch-compliance.sh \
  --kernel-src . \
  --base a19888edbd0a4a46d624c9abe66d5f5ef4042abb \
  --head c3dee7ea1f1665d9319c12f7b8a13e928914eb43

---

✅ tag-check

Status: PASS

The commit subject starts with QCLINUX:, which is a valid prefix for the tag-check requirement. Since the target branch is qcom-6.18.y (not qcom-next or qcom-next-staging), every commit must have a prefix tag, and this commit satisfies that requirement.

Valid prefixes: FROMLIST:, FROMGIT:, UPSTREAM:, BACKPORT:, QCLINUX:, PENDING:, WORKAROUND:

---

Verdict

Merge as-is — The check-patch-compliance failure is a known limitation for vendor-only commits using the QCLINUX: prefix. All other checkers passed or were appropriately skipped. The commit is properly formatted with:

• ✅ Valid QCLINUX: prefix (required for qcom-6.18.y branch)
• ✅ Proper Signed-off-by: trailer
• ✅ Clear commit message explaining the change
• ✅ No coding style issues
• ✅ Config-only change (no code/DTS/binding modifications)

This is a legitimate vendor-specific configuration change that cannot satisfy the upstream-link requirement of check-patch-compliance.
