nbd_set_tls_verify_peer - Man Page

 #include <libnbd.h>

 int nbd_set_tls_verify_peer (
       struct nbd_handle *h, bool verify
     );

Set this flag to control whether libnbd will verify the identity of the server from the server's certificate and the certificate authority.  This defaults to true when connecting to TCP servers using TLS certificate authentication, and false otherwise.

This function may be called regardless of whether TLS is supported, but will have no effect unless nbd_set_tls(3) is also used to request or require TLS.

If the call is successful the function returns 0.

On error -1 is returned.

Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

The following parameters must not be NULL: h. For more information see "Non-NULL parameters" in libnbd(3).

nbd_set_tls_verify_peer can be called when the handle is in the following state:

 ┌─────────────────────────────────────┬─────────────────────────┐
 │ Handle created, before connecting   │ ✅ allowed              │
 │ Connecting                          │ ❌ error                │
 │ Connecting & handshaking (opt_mode) │ ❌ error                │
 │ Connected to the server             │ ❌ error                │
 │ Connection shut down                │ ❌ error                │
 │ Handle dead                         │ ❌ error                │
 └─────────────────────────────────────┴─────────────────────────┘

This function first appeared in libnbd 1.0.

If you need to test if this function is available at compile time check if the following macro is defined:

 #define LIBNBD_HAVE_NBD_SET_TLS_VERIFY_PEER 1

nbd_create(3), nbd_get_tls_verify_peer(3), nbd_set_tls(3), libnbd(3).
