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

lib: Change return type of fevent to ssize_t

2020-03-15T13:26:49+00:00

The return type was still an int, but since it returns the number of events, it should be an ssize_t. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irm: Revise naming API

2020-03-15T13:20:38+00:00

This revises the naming API to treat names (or reg_name in the source) as first-class citizens of the architecture. This is more in line with the way they are described in the article. Operations have been added to create/destroy names independently of registering. This was previously done only as part of register, and there was no way to delete a name from the IRMd. The create call now allows specifying a policy for load-balancing incoming flows for a name. The default is the new round-robin load-balancer, the previous behaviour is still available as a spillover load-balancer. The register calls will still create a name if it doesn't exist, with the default round-robin load-balancer. The tools now have a "name" section, so the format is now irm name ...

ouroboros: Rename service to ouroboros

2020-03-14T14:39:07+00:00

The service was called "irmd", but it makes a bit more sense to give it the system name. Only the service name is changed, the irmd binary remains irmd. 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: Fix deadlock in threadpool manager

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

There was a rare deadlock upon destruction of the threadpool manager because the threads were cancelled/joined under lock. 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
