From a7c6bc008fe006f005d5c15d3f883572ad5defc5 Mon Sep 17 00:00:00 2001 From: Leonardo Bras Date: Wed, 18 May 2022 02:52:25 -0300 Subject: [PATCH 20/37] migration: Add migrate_use_tls() helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Leonardo Brás RH-MergeRequest: 191: MSG_ZEROCOPY + Multifd @ rhel8.7 RH-Commit: [20/26] 02afc2e60f1abbf6db45d83e54a18b66dad52426 RH-Bugzilla: 2072049 RH-Acked-by: Peter Xu RH-Acked-by: Daniel P. Berrangé RH-Acked-by: Dr. David Alan Gilbert A lot of places check parameters.tls_creds in order to evaluate if TLS is in use, and sometimes call migrate_get_current() just for that test. Add new helper function migrate_use_tls() in order to simplify testing for TLS usage. Signed-off-by: Leonardo Bras Reviewed-by: Juan Quintela Reviewed-by: Peter Xu Reviewed-by: Daniel P.
