lib: Make UNIX socket buffer size configurable

2018-05-03T10:26:48+00:00

This makes the buffer size used by the UNIX sockets configurable. In case of a lot of IPCPs in the system it might become too small with the default value, resulting in irm command failures. The user can now easily configure it with an adequate value. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

lib: Shut rx buffer down before cleanup and exit

2018-04-26T09:56:59+00:00

If a program exits, it cleans its read buffer. However, another process could still write a packet in that buffer, which would cause the IPCP or IRMd to run into an assertion failure on shutdown. Setting the rbuff to ACL_FLOWDOWN prevents this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Unmount stale FUSE mountpoints

2018-04-26T07:56:02+00:00

This will unmount a stale FUSE mountpoint (an IPCP with the same pid exited ungracefully on the system) before trying to create it. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix bad unlinking of old shared memory

2018-04-25T14:00:01+00:00

A previous commit tried to stat the shared memory file in case it was already there, but stat does not seem to work for shared memory files. This simply omits the O_EXCL attribute upon creation of the shared memory file, since pids are unique anyway. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

lib: Unlink old flow set shared memory

2018-04-25T12:53:05+00:00

This unlinks previously allocated flow set shared memory. It could be lingering in case an application with the same pid was SIGKILLED, and didn't clean up its flow set shared memory. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

ipcpd: Avoid unnecessary copy in eth reader

2018-04-05T08:32:55+00:00

This reads from the Ethernet device directly into the rdrbuff to avoid a copy on the read side in the Ethernet IPCPs. This does not work for the netmap device. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Fix memleak when failing to list ipcps

2018-03-22T15:29:06+00:00

The list_ipcps call had a memleak in the failure case. Also fixes a compiler warning for a possible uninitialized variable and renumbers the gpb ipcpd message fields. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Simplify reg/unreg API

2018-03-22T11:36:58+00:00

The reg/unreg API is simplified to registering and unregistering a single name with a single IPCP. The functionality associated with registering names was moved from the IRMd to the irm tool. The function to list IPCPs was simplified to return all IPCPs in the system with their basic properties needed for management. The above changes led to some needed changes in the irm tool and the management functions that were depending on the previous behaviour of list_ipcps. Command line functionality to list IPCPs in the system is also added to the irm tool. Some older code was refactored. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Allow disabling partial read

2018-03-19T09:29:21+00:00

This allows disabling partial reads. It adds a flag FLOWFRNOPART that disables partial reads. Partial read is different from partial delivery (FRCTFPARTIAL), which allows delivery of fragments of an incomplete packet and thus potentially corrupted data. FLOWFRNOPART will never deliver corrupted data (unless FRCTFPARTIAL is also set). If FLOWFRNOPART is set and the buffer provided to flow_read is too small for the SDU, that SDU will be discarded and -EMSGSIZE is returned; Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Simplify some code in rdrbuff

2018-03-16T12:38:06+00:00

This simplifies some functions in the rdrbuff. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
