CVE-2021-47215

In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: kTLS, Fix crash in RX resync flow For the TLS RX resync flow, we
maintain a list of TLS contexts that require some attention, to communicate
their resync information to the HW. Here we fix list corruptions, by
protecting the entries against movements coming from
resync_handle_seq_match(), until their resync handling in napi is fully
completed.
