2021-09-17memif: avoid double pool_put on a clib_fileSteven Luong1-1/+2
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

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-2/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2021-04-16tests: cpus awarenessKlement Sekera1-1/+14
Introduce MAX_CPUS parameters to control maximum number of CPUs used by VPP(s) during testing, with default value 'auto' corresponding to all CPUs available. Calculate test CPU requirements by taking into account the number of workers, so a test requires 1 (main thread) + # of worker CPUs. When running tests, keep track of both running test jobs (controlled by TEST_JOBS parameter) and free CPUs. This then causes two limits in the system - to not exceed number of jobs in parallel but also to not exceed number of CPUs available. Skip tests which require more CPUs than are available in system (or more than MAX_CPUS) and print a warning message.
