Re: [PATCH V3] rtlwifi: rtl_pci: Fix problem of too small skb->len

Larry Finger Larry.Finger@lwfinger.net writes:

In commit 8020919a9b99 ("mac80211: Properly handle SKB with radiotap only"), buffers whose length is too short cause a WARN_ON(1) to be executed. This change exposed a fault in rtlwifi drivers, which is fixed by regarding packets with skb->len <= FCS_LEN as though they are in error and dropping them. The test is now annotated as likely.

V2 - content dropped V3 - changed fix to drop packet rather than arbitrarily increasing the length.

Much better, thanks.

Material for 5.4.

Ok, I'll queue it for v5.4.
