# DF-0505 — Low-severity source-confirmation

**Verdict:** NOT_REPRODUCED

**Impact:** none   **Confidence:** certain

**Kernel ref:** `netgraph7/ng_fec.c:188`

## Mechanism / why
FALSE POSITIVE: ng_fec_input declaration (ng_fec.c:188-190) IS 4-param matching the if_input slot; only the definition is 2-param, so extra args are dropped harmlessly per the x86-64 ABI. No corruption.

## Recommended fix
No code change needed: false positive (declaration matches the slot; extra args harmlessly dropped).

## Phase 8 (combined build)
All 80 Low-severity fixes were batched into one patch (`../_batch_low/combined_all.patch`) and applied to the in-guest `/usr/src`. A single `make -j6 nativekernel KERNCONF=X86_64_GENERIC` completed rc=0 with **0 errors under -Werror** (`../_batch_low/fix_build.log`). The GENERIC-compiled fixes (net/radix, netinet, netinet6, wlan, wlan_ccmp, wlan_wep, altq, if_mib) are build-validated; module-only/netgraph/ipfw3/netsmb/vlan/sl/disc fixes apply cleanly to source (those subsystems are optional, not compiled into GENERIC).
