2024-01-19memif: use VPP cacheline size for memif when compiling within VPPMohsin Kazmi1-0/+2
Type: make memif.h file is independent code which can be used outside of VPP. Hence it uses its own cacheline size MACRO. This patch sets the value of MEMIF_CACHELINE_SIZE in the cmake file for memif plugin to VPP_CACHE_LINE_SIZE.

memif_disconect may be called without barrier sync. It removes stuff in mq without protection which may cause troubles for memif RX/TX worker threads. The fix is to protect mq removal in memif_disconnect. Type: fix Change-Id: I368c466d1f13df98980dfa87e8442fbcd822a428 Signed-off-by: Steven Luong <sluong@cisco.com>

2023-04-25memif: support dma optionMarvin Liu8-20/+925
Introduce async model into memif by utilizing new DMA API. Original process is broken down to submission stage and completion stage. As multiple submissions may in flight simultaneously, per thread data is no longer safe, now replace thread data into each dma data structure. As slave side already support zero copy mode, DMA option is only added in master side.

2023-03-06memif: autogenerate socket_idsNathan Skrzypczak5-0/+181
This patch adds an API memif_socket_filename_add_del_v2 that allows autogenerating memif socket_id when passing ~0 in the socket_id field. It opportunistically walks the hash to find a free ID to use, and returns it in the reply. socket_filename also becomes a variable length string, to accomodate for longer names (in case a netns gets passed) Type: feature Change-Id: I33fc3e1cf553af27579d6bad8691b22b530531cc Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

2022-08-30memif: Process bad descriptors correctly in memif_process_descSteven Luong1-10/+35
When there is a bad descriptor, it may in the beginning, in the middle, or at the end of the batch if the batch has more than 3 descriptors. When processing a bad descriptor is encountered in the batch, we need to rollback n_buffers in memif_process_desc(), or the statement in the same function memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy, dst_off, n_buffers - 1); is wrong because it picks up the wrong buffer_vec_index of the bad descriptor while parsing a good descriptor immediately following the bad descriptor. n_buffers was incremented in the beginning of while (n_left) loop. The other problem is we should count the number of bad packets and reduce ptd->n_packets to get the correct number of packets for subsequent processing in device_input. The last fix is to check if n_buffers == 0 in device_input and skip doing any descriptor copy. This case can happen when all the descriptors are bad in the batch.

2022-08-17memif: crash on recceiving a bad descriptorSteven Luong1-1/+1
We validate each descriptor via memif_validate_desc_data and set desc_status to non-zero for the corresponding descriptor when the descriptor is bad. However, desc_status is not propagated back to xor_status in memif_validate_desc_data which eventually sets ptd->xor_status. Not setting ptd->xor_status causes us to treat all descriptors as "simple". In that case, when we try to copy also the bad descriptors to the buffers, it results a crash since desc_data is not set to point to the correct memory in the descriptor. The fix is to set xor_status in memif_validate_desc_data such that if there is a bad descriptor in the frame, "is_simple" is set to false and we have to selectively copy only the good descriptors to the buffers.

When memif CP processes the socket connection error, it may go through the following code paths which may eventually cause double pool_put on a clib_file memif_master_conn_fd_error:633 -> memif_disconnect -> memif_socket_close -> memif_file_del_by_index -> clib_file_del_by_index -> clib_file_del -> pool_put After memif_master_conn_fd_error:633, the code continues on memif_maser_conn_fd_error:651 -> memif_file_del -> clib_file_del -> pool_put The fix is to skip calling memif_file_del in memif_master_conn_fd_error:651 if uf->file_descriptor == ~0 to catch problem from all possible paths in memif_master_conn_fd_error Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I0960998db1ff358a8ddd4a5e22188a244eccd270
