2021-10-27libmemif: fix gcc strict-proto errorMatthew Giassa1-3/+3
- Changing function prototypes for a couple libmemif functions so that gcc will successfully compile with the "-Wstrict-prototypes" flag enabled. - Re-ran unit tests via "make test" locally on Ubuntu 20.04 LTS x64. One issue (likely unrelated to patch): * Testcase name: Bidirectional Forwarding Detection (BFD) ERROR: put session admin-up and admin-down [test_bfd.BFD4TestCase.test_admin_up_down] Type: fix Change-Id: Ibcb7210873d39aec9348fe8ac7eebc78d089d8e0 Signed-off-by: Matthew Giassa <mgiassa@cisco.com>
2021-09-27libmemif: refactor connection establishmentJakub Grajciar1-148/+183
per_thread_ namespace fuctionality replaced by memif socket. Interfaces are grouped by memif socket which holds interface database. Each thread can create it's unique memif socket. The path name can be equal across threads so that the app only uses one UNIX socket. In case of listener socket, listener fd can be obtained and set using APIs. This change allows: - No lookup on file descriptor events - improves interrupt handling - Loopback support (connect two interfaces in one app) - usefull for debugging and testing - Improves code readability by providing control channel abstraction for each interface and listener sockets Type: refactor Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: I1b8261042431c0376646ab4c4c831f6e59dd3eed

2019-08-21libmemif: introduce 'memif_per_thread_' namespaceJakub Grajciar1-4/+132
APIs in 'memif_per_thread_' namespace are used to split the global database into separate databases, to improve multi-thread use cases. Using 'memif_per_thread_init' client can create separate libmemif databases (libmemif_main_t). Client will reference these databases using memif_per_thread_handle_t. Each database requires unique socket. Created interface will be stored in the same database as the socket passed in connection arguments.

2019-07-02libmemif: version 3.0Jakub Grajciar1-7/+41
Add support for multi-thread connection establishment. - control_fd_update() callback now passes private context associated with updated file descriptor. File descriptor can belong to memif socket, memif connection or timerfd. In case of timerfd the context is NULL. - memif_create_socket() new API. Creates memif socket handle to be passed to memif_create() in memif_conn_args_t. This API allows to pass private context whenever the file descriptor is updated. - memif_delete_socket() new API. Deletes memif socket. Socket must not be in use by any interface. Type: feature Change-Id: I7ca4e4349595d4477195f1c32403d3e3a6eb5361 Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
