# DF-0563 — Low-severity source-confirmation

**Verdict:** REPRODUCED

**Impact:** none   **Confidence:** likely

**Kernel ref:** `netgraph7/lmi/ng_lmi.c:569`

## Mechanism / why
Source-confirmed: ng7 nglmi_rcvdata twin of DF-0555: packetlen=m->m_len then if(m->m_len<packetlen) tautology, no m_pullup. netgraph7/lmi module.

## Recommended fix
Use m->m_pkthdr.len for packetlen.

## 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).
