| * | cmake: Make missing Module.symvers a warning | Simon Rettberg | 2023-06-09 | 1 | -1/+3 | |
| | | | | | | | | Since on github, we just compile against downloaded sources without having a matching built kernel, a missing Module.symvers breaks the action. While the resulting built kernel module might not be of much use, all we want to know is whether it compiles. | |||||

| * | [FUSE] Make initial connect entirely parallel wrt servers | Simon Rettberg | 2023-02-12 | 1 | -111/+232 | |
| | | | | | | | | | | | | | Previously, we only did the actual socket connect in a concurrent matter. Once a connection was successfully established, we did a blocking handshake on the protocol level. If the server war particularly slow, this was bad as we would not try other servers until after this. Throw out the previous non-blocking async connect logic, switching to a multi-threaded approach, that spawns one thread per host/ip, offset by 200ms, until one of the attempts succeeds. | |||||

| * | [SERVER] Don't establish uplink when loading image on startup | Simon Rettberg | 2022-09-13 | 1 | -1/+1 | |
| | | | | | | | | Bringing up a proxy that has been offline for some time will trigger lots of loads and replication on other proxies when booting up again. Just wait until a client actually needs an image before establishing an uplink connection. | |||||

| * | [KERNEL] IOCTL_SWITCH: Always boost/fake RTT values | Simon Rettberg | 2022-03-24 | 1 | -17/+17 | |
| | | | | | Even if we didn't switch because we already use the requested server. | |||||
| * | [KERNEL] Fix possible stall when switching server | Simon Rettberg | 2022-03-04 | 1 | -1/+9 | |
| | | | | | | | | If we switch to a different server when we only have something in the send list but nothing in the recv list, the send worker would not have gotten invoked. Now we unconditionally trigger the send worker when asked to re-queue any pending requests. | |||||

| * | [KERNEL] Refactor to use workqueues and blk-mq only | Simon Rettberg | 2022-02-18 | 11 | -1172/+918 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using workqueues frees us from having to manage the lifecycle of three dedicated threads. Discovery (alt server checks) and sending keepalive packets is now done using work on the power efficient system queue. Sending and receiving happens via dedicated work queues with higher priority. blk-mq has also been around for quite a while in the kernel, so switching to it doesn't hurt backwards compatibility. As the code is now refactored to work more as blk-mq is designed, backwards compatibility even improved while at the same time freeing us from an arsenal of macros that were required to make the blk-mq port look and feel like the old implementation. For example, the code now compiles on CentOS 7 with kernel 3.10 without requiring special macros to detect the heavily modified RedHat kernel with all its backported features. A few other design limitations have been rectified along the way, e.g. switching to another server now doesn't internally disconnect from the current one first, which theoretically could lead to a non-working setup, if the new server isn't reachable and then - because of some transient network error - switching back also fails. As the discover-thread was torn down from the disconnect call, the connection would also not repair itself eventually. we now establish the new connection in parallel to the old one, and only if that succeeds do we replace the old one with it, similar to how the automatic alt-server switch already does it. | |||||

| * | [KERNEL] Don't log connect failures as errors for RTT checks | Simon Rettberg | 2021-10-19 | 1 | -16/+24 | |
| | | | | | | | | This spams scary red errors to dmesg when really an unreachable alt server isn't that much of a deal during normal operation. Change the log level to debug instead. Might even consider not printing anything at all. | |||||
| * | [BUILD] CheckPatch: Quote variable to avoid error if empty | Simon Rettberg | 2021-10-19 | 1 | -1/+1 | |
| | | | | | | | | | | | The variable is most likely empty if the according kernel headers directory was deleted. However, as it currently stands, cmake is complaining about too few arguments, which isn't really helpful to the user. Instead, quote the variable to make cmake finish, and have the actual compile process of the kernel module fail, which will yield a much more helpful error message. | |||||

| * | server.conf: Update uplinkTimeout to match default valuev3.10 | Simon Rettberg | 2021-05-11 | 1 | -1/+1 | |

| * | [SERVER] Add minRequestSize: Enlarge relayed requests | Simon Rettberg | 2021-05-11 | 3 | -16/+48 | |
| | | | | | | | | | | | Any request from a client being relayed to an uplink server will have its size extended to this value. It will also be applied to background replication requests, if the BGR mode is FULL. As request coalescing is currently very primitive, this setting should usually be left diabled, and bgrWindowSize used instead, if appropriate. If you enable this, set it to something large (1M+), or it might have adverse effects. | |||||
