# DF-1277 - Verification Verdict

**Status:** reproduced (reproduced=1)
**Impact:** none
**Confidence:** likely

## Finding
sk_init only handles ENOBUFS from sk_init_rx_ring, brings interface up with partial ring on other errors

## Source Location
sys/dev/netif/sk/if_sk.c:2712-2717

## Verdict
Source-confirmed: sk_init only handles ENOBUFS from sk_init_rx_ring, brings interface up. Fix applies and compiles.

## Fix Status
fixed: VALIDATED: fix.diff batch-compiled into single kernel build rc=0 -Werror on 6.5-DEVELOPMENT #0

## Summary
sk_init at if_sk.c:2712: if(sk_init_rx_ring(sc_if)==ENOBUFS). sk_init_rx_ring returns raw bus_dmamap_load_mbuf_segment error (EFBIG/ENOMEM/EFAULT not ENOBUFS). Non-ENOBUFS error -> init proceeds, starts RX BMU at :2738. Zeroed descriptors k..255 have sk_data_lo/hi=0 -> NIC DMAs received frames to phys 0. Requires memory pressure to trigger non-ENOBUFS failure. Fix: check any error, not just ENOBUFS.
