[PATCH v3 0/3] wifi: carl9170: firmware trust boundary hardening

[Tristan Madani]

From: Tristan Madani <tristan@xxxxxxxxxxxxxxxxxxx>

This series adds missing bounds checks for firmware-controlled fields
in the carl9170 USB driver.

Patch 1 bounds the cmd callback memcpy to prevent heap overflow from
an oversized firmware response. Patch 2 fixes an off-by-two in the TX
status handler. Patch 3 caps the failover copy to rx_failover_missing
bytes, using min_t per Christian Lamparter.

Changes in v3:
  - Regenerated from wireless-next with proper git format-patch.

Changes in v2:
  - Use min_t() instead of separate if-check in patch 3, per
    Christian Lamparter.
