2021-02-15vlib: refactor checksum offload supportMohsin Kazmi3-15/+25
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-05-04misc: binary api fuzz test fixesDave Barach1-1/+1
Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API messages, e.g. by xoring random data into them before processing. We specifically exempt client connection messages, and inband debug CLI messages. We step over msg_id, client index, client context, and sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn anything. The goal is to reduce the number of crashes caused to zero. We're fairly close with this patch. Add vl_msg_api_max_length(void *mp), which returns the maximum plausible length for a binary API message. Use it to hardern vl_api_from_api_to_new_vec(...) which takes an additional argument - message pointer - so it can verify that astr->length is sane. If it's not sane, return a u8 *vector of the form "insane astr->length nnnn\0". Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...) and vl_api_dhcp6_pd_send_client_message_t_handler(...). Add a fairly effective binary API fuzz hook to the unittest plugin, and modify the "make test" framework.py to pass "api-fuzz { on|off }" to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I0157267652a163c01553d5267620f719cc6c3bde
2020-04-15pg: set vnet buffer flags in pg streamsDave Barach3-1/+11
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

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.

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.
