In one of its commits [1] libssh2 changed the 'text' member of LIBSSH2_USERAUTH_KBDINT_PROMPT struct from 'char' to 'unsigned char'. But we g_strdup() the member in order to fill 'prompt' member of virConnectCredential struct. Typecast the value to avoid warnings. Also, drop @prompt variable, as it's needless. 1: https://github.com/libssh2/libssh2/commit/83853f8aea0e2f739cacd491632eb7f... Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- Here's a somewhat green CI: https://gitlab.com/MichalPrivoznik/libvirt/-/pipelines/889599454 I mean, we still have failures on rawhide, but that's because numad was temporarily removed from repos, but they are bringing it back. So ignore that part. Apparently our CI images were not rebuilt this morning. src/rpc/virnetsshsession.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/src/rpc/virnetsshsession.c b/src/rpc/virnetsshsession.c index f84805825b..1df43bb044 100644 --- a/src/rpc/virnetsshsession.c +++ b/src/rpc/virnetsshsession.c @@ -216,9 +216,7 @@ virNetSSHKbIntCb(const char *name G_GNUC_UNUSED, /* fill data structures for auth callback */ for (i = 0; i < num_prompts; i++) { - char *prompt; - prompt = g_strdup(prompts[i].text); - askcred[i].prompt = prompt; + askcred[i].prompt = g_strdup((char*)prompts[i].text); /* remove colon and trailing spaces from prompts, as default behavior * of libvirt's auth callback is to add them */ -- 2.39.3
