Jakub Kicinski d10523d0b3 net/tls: free the record on encryption error ... When tls_do_encryption() fails the SG lists are left with the SG_END and SG_CHAIN marks in place. One could hope that once encryption fails we will never see the record again, but that is in fact not true. Commit d3b18ad31f ("tls: add bpf support to sk_msg handling") added special handling to ENOMEM and ENOSPC errors which mean we may see the same record re-submitted. As suggested by John free the record, the BPF code is already doing just that.
