lib: Return number of written bytes on flow_write

2020-03-15T13:30:58+00:00

This is more in line with the write() system call and prepares for partial writes. Partial writes are disabled by default (and not yet implemented). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix locking in link_state policy

2020-03-14T14:38:49+00:00

There were updates under rdlock instead of wrlock, causing data races and trouble. Also speeds up shutdown a bit. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib, ipcpd: piggyback ECDHE on flow allocation

2020-02-25T07:21:09+00:00

The initial implementation for the ECDHE key exchange was doing the key exchange after a flow was established. The public keys are now sent allowg on the flow allocation messages, so that an encrypted tunnel can be created within 1 RTT. The flow allocation steps had to be extended to pass the opaque data ('piggybacking'). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Add unit tests for LFA and ECMP algorithms

2020-02-23T13:37:30+00:00

This adds tests for LFA and ECMP to the graph_test routine. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix infinite recursion in LFA

2020-02-23T13:37:27+00:00

There were bugs introduced in the LFA algorithm refactor causing infinite recursion and SEGV. The infinite recursion check was added as an explicit compiler flag to the build. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Use int instead of enum pol_pff

2020-02-16T18:04:41+00:00

Otherwise the compile will complain that the comparison of an unsigned enum expression < 0 is always false. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Fix double free, memleak and malloc check

2020-02-16T17:33:21+00:00

Some fixes in the multipath implementation related to memory management that showed up with the static analyzer. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

Add equal-cost multipath routing policy

2020-02-16T17:32:21+00:00

This adds an equal-cost multipath routing policy to Ouroboros, based on Nick Aerts' code. When selected, flows will send packets over all paths with equal cost (hop count). Path selection is round-robin. It does not yet take into account flows that are down. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix uninitialized variable in graph

2020-02-16T17:27:26+00:00

During refactor a variable initialization was removed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Rename hashtable to pft

2020-02-16T17:26:07+00:00

This makes the hashtable more tailored to a packet forwarding table (PFT). In the end not much of a change was needed, but now it's clear the pft maps a destination address to a list of (outgoing) fds. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
