| * | | | ipcpd: Fix log message and lockdimitri staessens2016-10-231-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Remote requests for a flow that's locally deallocated should not generate an error. Sending messages should not be under lock.
| * | | | ipcpd: Improve locking in ipcp-datadimitri staessens2016-10-232-42/+76
| | | | | | | | | | | | | | | | | | | | This solves some potential data races in the shims.

| | * lib: Stabilise flow allocationdimitri staessens2016-10-235-44/+26
| |/ |/| | | | | | | | | | | Deallocation was reverted to a synchronoous operation between the AP, IRMd and IPCP in order to avoid inconsistent states of the port_id. Fixes some memory leaks, particularly the shm_flow_set is now closed upon deallocation.

| * dev, ipcp: Fix setting default flow optionsdimitri staessens2016-10-232-9/+3
| | | | | | | | | | The default flow options were not set when a flow allocation request arrives remotely. This went unnoticed due to a previous bug.

| * build: Remove the gethostbyname checkdimitri staessens2016-10-231-17/+0
| | | | | | | | | | gethostbyname is included in POSIX 2001. Ouroboros requires at least POSIX 2001 and recommends POSIX 2008 for stable builds.
| * build: Disable compilation flagsdimitri staessens2016-10-231-3/+4
| | | | | | | | | | | | | | pthread_cleanup handlers make gcc and clang fail the -Wclobbered check in release builds. Swig generates switch statements without a default, making the -Wswitch-default check fail. The -Wstrict-overflow=5 flag was removed.

| | | | | | | | The rdrbuff was previously closed before the remaining SDUs were removed.

| | | | | | | | | | An untested (and wrong) modification to the fqueue was mistakenly added to a previous commit. This corrects the bad code.

| | | | | | | | | | This has the code checked with -Wcast-qual and -Wconversion flags. These flags were removed because SWIG generated code fails.

| * lib: Move rbuff creation/destruction to IRMddimitri staessens2016-10-217-85/+106
| | | | | | | | | | This stabilises flow allocation now that the rbuffs are created upon flow allocation. Only the IRMd can sync this process sufficiently.
| * lib: Demultiplex the fast pathdimitri staessens2016-10-2127-1145/+1642
| | | | | | | | | | | | | | | | The fast path will now use an incoming ring buffer per flow per process. This necessitated the development of a new method for the asynchronous io call, which is now based on an event queue system for scalability (fqueue). The ipcpd's and tools have been updated to this API.

| | | | | | | | | | | | | | Added the missing implementation of setting read/write options for flows. This allows applications to block the fast path for remotes. IPCPs can use this to block the fast path for the N + 1 flow when receiving remote deallocation requests.

| * ipcpd: normal: Improve upon the internal designSander Vrijders2016-10-1211-574/+411
| | | | | | | | | | | | | | | | This commit will remove the RMT component from the normal IPCP, as some of its functionality would else be duplicated in the FMGR. Now all reading from flows, either N-1 or N+1 is done in the FMGR, then either passed to the FRCT or a lookup is performed in the PFF (not there yet) and the PDU is forwarded.

| |/ |/| | | | | | | | | | | This is the first version of the fast path bootstrap in the normal IPCP. It sets up a connection with the other end, and creates the appropriate data structures. N+1 and N-1 SDUs are read and written and passed through the right components.
