2023-07-29net/handshake: Add API for sending TLS Closure alertsChuck Lever1-0/+23
This helper sends an alert only if a TLS session was established. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Link: https://lore.kernel.org/r/169047936730.5241.618595693821012638.stgit@oracle-102.nfsv4bat.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-05-25net/handshake: Enable the SNI extension to work properlyChuck Lever1-0/+8
Enable the upper layer protocol to specify the SNI peername. This avoids the need for tlshd to use a DNS lookup, which can return a hostname that doesn't match the incoming certificate's SubjectName. Fixes: 2fd5532044a8 ("net/handshake: Add a kernel API for requesting a TLSv1.3 handshake") Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-04-20net/handshake: Add Kunit tests for the handshake consumer APIChuck Lever1-0/+1
These verify the API contracts and help exercise lifetime rules for consumer sockets and handshake_req structures. One way to run these tests: ./tools/testing/kunit/kunit.py run --kunitconfig ./net/handshake/.kunitconfig Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-04-20net/handshake: Add a kernel API for requesting a TLSv1.3 handshakeChuck Lever1-0/+417
To enable kernel consumers of TLS to request a TLS handshake, add support to net/handshake/ to request a handshake upcall. This patch also acts as a template for adding handshake upcall support for other kernel transport layer security providers.
