lightningd/lightningd: start HSM at initialization time. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2017-01-10 06:08:33 +01:00			`#ifndef LIGHTNING_LIGHTNINGD_HSM_CONTROL_H`

lightningd/hsm_control: use a simple fd for HSM. Now we're always sync, just use an fd. Put the hsm_sync_read() helper here, too, and do HSM init sync which makes things much simpler.

lightningd: create hsm_get_client_fd() helper. We're going to use this more when we hand hsm fds to openingd, onchaind and closingd. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2018-07-09 13:17:59 +02:00			`#include <hsmd/capabilities.h>`

Use node_id everywhere for nodes. I tried to just do gossipd, but it was uncontainable, so this ended up being a complete sweep. We didn't get much space saving in gossipd, even though we should save 24 bytes per node. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2019-04-08 11:58:32 +02:00			`struct node_id;`
hsm: decouple hsm from wallet; init before wallet We're going to use the hsm for a migration, so we need to set up the HSM before we get to the wallet migration code. All that this requires is removing the places in HSM init that we touch the database struct -- easy enough to accomplish by passing the required field back out from init, and then associating it onto the wallet after it's been initialized. 2020-05-26 23:06:13 +02:00			`struct ext_key;`

lightningd: use hsm_get_client_fd() helper for global daemons too. We couldn't use it before because it asserted dbid was non-zero. Remove assert and save some code.
