* secret-service: Add proper logging procedure and log to syslog.Ludovic Courtès2020-09-29
| | | | | | * gnu/build/secret-service.scm (log): New macro. (secret-service-send-secrets, secret-service-receive-secrets): Use it instead of raw 'format' calls.
* services: secret-service: Add initial client/server handshake.Ludovic Courtès2020-09-29
| | | | | | | | | | | | | | | This allows the client running on the host to know when it's actually connect to the server running in the guest. Failing that, the client would connect right away to QEMU and send secrets even though the server is not running yet in the guest, which is unreliable. * gnu/build/secret-service.scm (secret-service-send-secrets): Add #:handshake-timeout. Read from SOCK an initial message from the server. Return #f on error. (secret-service-receive-secrets): Send 'secret-service-server' message to the client. Close SOCK upon timeout. * gnu/services/virtualization.scm (hurd-vm-shepherd-service): 'start' method returns #f when 'secret-service-send-secrets' returns #f.
* secret-service: Fix file port leak in 'secret-service-send-secrets'.Ludovic Courtès2020-09-29
| | | | | * gnu/build/secret-service.scm (secret-service-send-secrets): Use 'call-with-input-file' instead of 'open-input-file'.
* secret-service: Add a timeout when waiting for a client.Ludovic Courtès2020-09-29
| | | | | | | | * gnu/build/secret-service.scm (secret-service-receive-secrets) [wait-for-client]: Call 'select' with a 60s timeout before 'accept'. Return #f upon timeout. [read-secrets]: Return FILES on success. Adjust caller of 'wait-for-client' to handle #f.
* secret-service: Clarify the origin of messages.Ludovic Courtès2020-09-29
| | | | | * gnu/build/secret-service.scm (secret-service-send-secrets) (secret-service-receive-secrets): Prefix messages by "secret service".
* services: Add secret-service-type.Jan (janneke) Nieuwenhuizen2020-09-01
This adds a "secret-service" that can be added to a Childhurd VM to receive out-of-band secrets (keys) sent from the host. Co-authored-by: Ludovic Courtès <ludo@gnu.org> * gnu/services/virtualization.scm (secret-service-activation): New procedure. (secret-service-type): New variable. * gnu/build/secret-service.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
