2019-10-03misc: add "maxframe" and "rate" to packet-generator cli.Christian E. Hopps3-5/+13
Allow for setting the maximum number of generated packets to be included in the frame passed to next nodes. This is very important for testing code which may be susceptible to multi-frame vs single-frame bugs (e.g., code that is doing re-ordering where packets may be buffered between frames). Update: - remove redundant packet "rate" option. - reduce n_max_frame to u32 as that's what pulled from the CLI. Type: feature Signed-off-by: Christian E.

2019-09-23interface: use the correct condition for checking if the pcap fd is openAndrew Yourtchenko1-1/+1
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.

Beside, the rx02.pcap file will not be created. solution: separate the pcap_close() out of pcap_write() Change-Id: Iedeb46f9cf0a4cb12449fd75a4014f95f3bb3fa8 Signed-off-by: Jack Xu <jack.c.xu@ericsson.com>

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-05-09add mactime plugin unit / code coverage testsDave Barach3-20/+30
The unit and code coverage tests are boring. The rest of the patch involves test and packet-generator infra cleanups. Teach the "make test-xxx" family of targets to set the api test plugin path correctly, to make "binary-api <api-message-name> <args>" debug CLI commands work correctly in the "make test" environment. Unfortunately involves both the top-level and test Makefiles. Add a minor pg cli feature, a CLI to manually set s->sw_if_index[VLIB_TX]. Consider the case where one configures an interface with both a device-input and an output feature. To test the output feature using the pg, it's necessary to inject packets into the interface output node with both b->sw_if_index[VLIB_TX] and b->sw_if_index[VLIB_RX] set correctly. For example: packet-generator new { name tx limit 15 size 128-128 interface local0 # rx: device input feature not configured on local0 tx-interface loop0 # tx: output node requires b->sw_if_index[VLIB_TX] node loop0-output data { hex 0x01005e7ffffa000dead0000008000102030405060708090a0b0c0d0e0f0102030405 } } Fix a longstanding bug in the packet generator stream setup. Remove kludges which set b->sw_if_index[VLIB_TX] to ~0 [in multiple places] instead of using the stream value s->sw_if_index[VLIB_TX], and setting THAT datum correctly.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-10/+29
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.
