net/tls: fix async operation
Mallesham reports the TLS with async accelerator was broken by commit d10523d0b3d7 ("net/tls: free the record on encryption error") because encryption can return -EINPROGRESS in such setups, which should not be treated as an error. The error is also present in the BPF path (likely copied from there). Reported-by: Mallesham Jatharakonda <mallesham.jatharakonda@oneconvergence.com> Fixes: d3b18ad31f93 ("tls: add bpf support to sk_msg handling") Fixes: d10523d0b3d7 ("net/tls: free the record on encryption error") Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Simon Horman <simon.horman@netronome.com> Signed-off-by: David S.
