NAME

       rpma_peer_cfg_from_descriptor - create a peer cfg from the descriptor

SYNOPSIS

             #include <librpma.h>

             struct rpma_peer_cfg;
             int rpma_peer_cfg_from_descriptor(const void *desc, size_t desc_size,
                             struct rpma_peer_cfg **pcfg_ptr);

DESCRIPTION

       rpma_peer_cfg_from_descriptor() creates a peer configuration object from the descriptor.

SECURITY WARNING

       An  attacker might modify the serialized remote node configuration while it is transferred
       via an unsecured connection (e.g. rdma_cm  private  data),  which  might  cause  different
       remote  persistency  method selections. The most dangerous situation is switching from the
       GPSPM mode to the APM one. Users  should  avoid  using  rpma_conn_get_private_data(3)  and
       rpma_conn_req_get_private_data(3) API calls and they should utilize TLS/SSL connections to
       transfer all configuration data between peers instead.

RETURN VALUE

       The rpma_peer_cfg_from_descriptor() function returns 0 on success or a negative error code
       on failure. rpma_peer_cfg_from_descriptor() does not set *pcfg_ptr value on failure.

ERRORS

       rpma_peer_cfg_from_descriptor() can fail with the following errors:

       •  RPMA_E_INVAL - desc or pcfg_ptr are NULL

       •  RPMA_E_NOMEM - out of memory
