Re: [PATCH net v2] tls: fix RX desync on overlapping skbs

Hello:

This patch was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

The TCP receive queue can hold adjacent skbs whose sequence ranges
overlap. The tls fast-path reads the record header with skb_copy_bits()
by byte offset, which assumes skbs do not overlap, so a header split
across the overlap is misread and the connection aborts
(-EMSGSIZE/-EINVAL). tls_strp_check_queue_ok() detects such overlaps but
only ran after the header was parsed, never covering the header itself.
