2021-03-04libmemif: verify length of transmitted buffersJakub Grajciar1-3/+4
In memif_tx_burst verify that total buffer size (data_offset + data_len) does not exceed buffer size. If not valid returns MEMIF_ERR_INVAL_ARG. Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: Ifae8f92344a401febbc1efd22c301356ccf83d44
2021-03-04libmemif: socket filename length 108Jakub Grajciar1-26/+2
Dynamic size array was causing trouble in strlcpy. LINUX allows for max 108 filename length, so we can use that to make the array constant size. Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: I76b1fc41f9d93cfbc9ad11bdca0c96a1fc261e84
2021-02-08libmemif: fix insecure uses of strncpyAndrew Yourtchenko1-25/+17
A calling patterm of "strncpy(dst, src, strlen(src))" invites a lot of troubles. However, even using the target size may result in a problem if the string is longer, since then the termination is not done. Use strlcpy(dst, src, sizeof(dst)), which will always null-terminate the string.

2019-08-21libmemif: introduce 'memif_per_thread_' namespaceJakub Grajciar1-76/+587
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 Grajciar1-262/+317
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>
