2019-09-30session: improve cliFlorin Coras7-148/+348
Type: feature Allow session cli filtering based on thread index, transport protocol, session state and range of session pool indices. For instance show session thread 1 proto tcp state ready range 0 20 verbose Shows the session ids for the first 20 tcp sessions in thread 1 that are in ready state. To avoid excessive output that could reasult in the worker barrier being held by the main thread for long periods of time, the session cli will only output: - session ids (verbose == 1) for a maximum of 50 sessions / worker - verbose > 1 details for a maximum of 10 sessions Change-Id: I2cfb351b548e2e0a1d5b4345810be613e2917d17 Signed-off-by: Florin Coras <fcoras@cisco.com> (cherry picked from commit 5bb23ecd098eac639641e2b3d62eb8744e0efef0)

2019-09-25interface: use the correct condition for checking if the pcap fd is openAndrew Yourtchenko4-4/+4
The 9af7e2e87e used a comparison that fd is >= 0 to check that the pcap needs closing. While the pcap_close() function does reset the file descriptor to -1, the freshly initialized structure has it equal to 0. This causes the VPP to close stdin if the packets are being seen on pg interface without the capture file being opened. This triggers the vpp attempting to read from STDIN (another bug), which results in running out of memory.

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.
