From 7dca6fc9edf52fbf6846deec9346217c495c235d Mon Sep 17 00:00:00 2001 From: John Gallagher Date: Tue, 5 Dec 2023 06:59:04 -0800 Subject: [PATCH 1/6] [wicketd] Add refresh-config subcommand instead of using curl (#4606) This allows us to add some time for refreshing a wicketd that hasn't fully started (and therefore isn't reachable on its dropshot server yet). Fixes https://github.com/oxidecomputer/omicron/issues/4604. Testing this is a little awkward because config refresh is only support on illumos via SMF, so I tested this by hand on `madrid`: 0. Disable wicketd (`svcadm disable wicketd`) 1. Install the new wicketd binary and `manifest.xml` in the switch zone 2. Import the new manifest.xml (`svccfg import /var/svc/manifest/site/wicketd/manifest.xml`) 3. (I expected to need to restore the config properties that sled-agent had set, but they persisted) 4. Enable wicketd and immediately try to refresh it (`svcadm enable wicketd && svcadm refresh wicketd`) In the wicketd logs, we see that the first refresh attempt failed because it fired before the dropshot server was up: ``` [ Dec 4 18:34:22 Executing start method ("ctrun -l child -o noorphan,regent /opt/oxide/wicketd/bin/wicketd run /var/svc/manifest/site/wicketd/config.toml --address [::1]:12226 --artifact-address [fdb0:a840:2504:355::2]:12227 --mgs-address [::1]:12225 --nex us-proxy-address [::]:12229 --baseboard-file /opt/oxide/baseboard.json --read-smf-config &"). ] [ Dec 4 18:34:22 Method "start" exited with status 0. ] [ Dec 4 18:34:22 Rereading configuration. ] note: configured to log to "/dev/stdout" [ Dec 4 18:34:22 Executing refresh method ("/opt/oxide/wicketd/bin/wicketd refresh-config /var/svc/manifest/site/wicketd/config.toml --address [::1]:12226"). ] note: configured to log to "/dev/stdout" 18:34:22.330Z WARN wicketd: failed to refresh wicketd config (attempt 1 of 3); will retry after 5s err = Communication Error: error sending request for url (http://[::1]:12226/reload-config): error trying to connect: tcp connect error: Connection refused (os error 146)\nCaused by:\n -> error sending request for url (http://[::1]:12226/reload-config) : error trying to connect: tcp connect error: Connection refused (os error 146)\n -> error trying to connect: tcp connect error: Connection refused (os error 146)\n -> tcp connect error: Connection refused (os error 146)\n -> Connection refused (os error 146) 18:34:22.396Z INFO wicketd (dropshot (wicketd)): listening file = /home/john/.cargo/git/checkouts/dropshot-a4a923d29dccc492/ff87a01/dropshot/src/server.rs:195 local_addr = [::1]:12226 ``` 10 seconds later, we see the successful connection, POST, and exit of the SMF `refresh`: ``` 18:34:32.332Z INFO wicketd (dropshot (wicketd)): accepted connection file = /home/john/.cargo/git/checkouts/dropshot-a4a923d29dccc492/ff87a01/dropshot/src/server.rs:769 local_addr = [::1]:12226 remote_addr = [::1]:32976 18:34:32.388Z INFO wicketd (dropshot (wicketd)): request completed file = /home/john/.cargo/git/checkouts/dropshot-a4a923d29dccc492/ff87a01/dropshot/src/server.rs:853 latency_us = 30475 local_addr = [::1]:12226 method = POST remote_addr = [::1]:32976 req_id = e0c2034a-0a99-45c1-a651-57249ca258f0 response_code = 204 uri = /reload-config [ Dec 4 18:34:32 Method "refresh" exited with status 0. ] ``` --- smf/wicketd/manifest.xml | 2 +- wicketd/Cargo.toml | 2 +- wicketd/src/bin/wicketd.rs | 41 ++++++++++++++++++++--- wicketd/src/lib.rs | 68 +++++++++++++++++++++++++++++++++++--- 4 files changed, 102 insertions(+), 11 deletions(-) diff --git a/smf/wicketd/manifest.xml b/smf/wicketd/manifest.xml index 778a7abf2d..b45ff1544b 100644 --- a/smf/wicketd/manifest.xml +++ b/smf/wicketd/manifest.xml @@ -32,7 +32,7 @@ it expected https). --> diff --git a/wicketd/Cargo.toml b/wicketd/Cargo.toml index 1360c28b19..97550342d0 100644 --- a/wicketd/Cargo.toml +++ b/wicketd/Cargo.toml @@ -58,6 +58,7 @@ sled-hardware.workspace = true tufaceous-lib.workspace = true update-engine.workspace = true wicket-common.workspace = true +wicketd-client.workspace = true omicron-workspace-hack.workspace = true [[bin]] @@ -83,4 +84,3 @@ tar.workspace = true tokio = { workspace = true, features = ["test-util"] } tufaceous.workspace = true wicket.workspace = true -wicketd-client.workspace = true diff --git a/wicketd/src/bin/wicketd.rs b/wicketd/src/bin/wicketd.rs index 887ac496e0..24fa802c79 100644 --- a/wicketd/src/bin/wicketd.rs +++ b/wicketd/src/bin/wicketd.rs @@ -5,6 +5,7 @@ //!
