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 the QCLINUX: prefix, which is not in the checker's allowed list of upstream-linkable prefixes.

Failure details:

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

Analysis:

The check-patch-compliance checker enforces a strict subset of prefixes that are upstream-linkable:

• ✅ Accepted: FROMLIST:, FROMGIT:, UPSTREAM:, BACKPORT:
• ❌ Rejected: QCLINUX:, PENDING:, WORKAROUND:

This is a known limitation of the checker — it does not accept vendor-internal prefixes like QCLINUX: even though they are valid and widely used in the Qualcomm Linux kernel tree for vendor-only changes.

Why QCLINUX: is appropriate here:

This commit enables CONFIG_XDP_SOCKETS in the Qualcomm-specific kernel config fragment (arch/arm64/configs/qcom.config). This is a vendor-specific configuration change with no upstream equivalent — it's not a patch that would be posted to LKML or merged into mainline. The QCLINUX: prefix correctly indicates this is a Qualcomm Linux-specific change.

Fix options:

1. Accept the checker failure (Recommended)

   • The QCLINUX: prefix is correct for this vendor-only config change
   • This is a known checker limitation for vendor-internal commits
   • No patch change needed

2. Change prefix to satisfy the checker (Not recommended)

   • Could use FROMLIST: + add a fake Link: tag, but this would be misleading
   • The commit is not posted upstream and never will be
   • This would misrepresent the nature of the change

Reproduce locally:

cd kernel
git log --oneline a5cf3debd8c3..36a37571e328
# Verify the commit subject starts with QCLINUX:

⚠️ tag-check (Manual Analysis)

Applies to: All branches except qcom-next and qcom-next-staging

Target branch: tech/all/config → tag-check is mandatory

Analysis:

The commit subject is:

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

The required prefix tags for branches other than qcom-next/qcom-next-staging are:

• FROMLIST:, FROMGIT:, UPSTREAM:, BACKPORT:, QCLINUX:, PENDING:, WORKAROUND:

Verdict: ✅ PASS

The commit subject starts with QCLINUX:, which is a valid prefix tag. The tag-check requirement is satisfied.

Note: While tag-check passes (the commit has a valid prefix), check-patch-compliance fails because it enforces a stricter subset of prefixes. These are two different checks with different acceptance criteria.

---

Verdict

Recommendation: ✅ Merge as-is

Rationale:

• All substantive checkers passed (checkpatch, dtb-check, dt-binding-check, sparse-check, check-uapi-headers)
• The check-patch-compliance failure is a known false positive for vendor-only commits
• The QCLINUX: prefix is correct and appropriate for this vendor-specific config change
• The commit has proper Signed-off-by: and a clear commit message
• No code quality, style, or technical issues detected

Context:
This is a single-line config change enabling CONFIG_XDP_SOCKETS=y in the Qualcomm kernel config fragment. It's a straightforward, low-risk change that enables AF_XDP zero-copy networking support on Qualcomm platforms. The checker failure is purely a tooling limitation, not a defect in the patch.
