lib: Use struct portevent internally

2022-03-30T13:12:25+00:00

The fqueues were relying on the fact that the portevent were two integers. This cleans that up a bit. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add np1_flow_read and np1_flow_write calls

2022-03-30T13:05:05+00:00

Reading/writing to (N + 1)-flows from the IPCP was using a raw QoS flow to bypass some functions in the ipcp_flow_read call. But this call was broken for keepalive packets. Fixing the ipcp_flow_read call for (N - 1) flows causes the IPCPs to drop 0-byte keepalive packets coming from (N + 1) client flows. >From now on, there is a dedicated call for (N + 1) reads/writes from the IPCPs that's more efficient and cleaner. The (N + 1) flow internal QoS is now also defaulted to a qos_np1 qosspec, instead of tampering with the qosspec requested by the (N + 1) client.

lib: Add rbuff support for FLOWPEER state

2022-03-30T13:05:05+00:00

This allows setting the FLOWPEER state on a flow to signal a peer is unresponsive. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Refactor reading packet from rbuff

2022-03-30T13:05:05+00:00

Reading packets from the rbuff and checking their validity (non-zero size, pass crc check, pass decryption) is now extracted into a function. Also adds a function to get the length of an sdu_du_buff instead of subtracting the tail and head pointers. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Don't log prefix in syslog

2022-03-30T12:56:39+00:00

Logging the prefix in the system logs has a lot of duplication, as the syslog already includes the name of the daemon. Maybe we should deprecate logging to stdout and focus on the syslog, revise things a bit to print internal component names if they are defined. For now, I think it's less annoying to read the syslog without the prefixes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipdpd: Pass MPL to application at flow_allocation

2022-03-08T16:40:17+00:00

The maximum packet lifetime (MPL) is a property of the flow that needs to be passed to the reliable transmission protocol (FRCP) for its correct operation. Previously, the value of MPL was set fixed as one of the (fixed) Delta-t parameters. This patch makes the MPL a property of the layer, and it can now be set per layer-type at build time. This is a step towards a proper MPL estimator in the flow allocator. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Make flow liveness timeout configurable

2022-03-03T11:00:54+00:00

The qosspec_t now has a timeout value that sets the timeout value of the flow. Flows with a peer that has timed out will now return -EFLOWPEER on flow_read() or flow_write(). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix waiting for FRCP to time out

2021-12-22T15:34:56+00:00

The timeout variable was not correctly passed to the IPCP, causing flow IDs to be reused immediately instead of waiting for the full Delta-t to expire. This caused all kinds of havoc with retransmissions in reliable flows. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Pass full path for RIB entries

2021-06-29T06:56:03+00:00

The read functions for the RIB will now receive the full path, instead of only the entry name. For IPCPs, we organized the RIB in an ///entries structure with a directory per component, so we don't need the full path at this point. For process flow information, it's a lot more convenient to organize it the following way ///stat We can then register/unregister the flow descriptor when the frct instance is created, and for getting the stats, we'd know the flow descriptor from the fuse file path. If we would create a file per flow instead of a directory per flow, something like //flows/ we'd need to do additional bookkeeping to list the contents of that directory (we would need to track all flows with an active FRCT instance), that fuse knows because it tracks the directories.
