2018-11-07selftests: add functionals test for UDP GROPaolo Abeni1-1/+1
Extends the existing udp programs to allow checking for proper GRO aggregation/GSO size, and run the tests via a shell script, using a veth pair with XDP program attached to trigger the GRO code path. rfc v3 -> v1: - use ip route to attach the xdp helper to the veth rfc v2 -> rfc v3: - add missing test program options documentation - fix sporatic test failures (receiver faster than sender) Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

2018-06-04selftests/net: add packet socket packet_snd testWillem de Bruijn1-2/+2
Add regression tests for PF_PACKET transmission using packet_snd. The TPACKET ring interface has tests for transmission and reception. This is an initial stab at the same for the send call based interface. Packets are sent over loopback, then read twice. The entire packet is read from another packet socket and compared. The packet is also verified to arrive at a UDP socket for protocol conformance. The test sends a packet over loopback, testing the following options (not the full cross-product): - SOCK_DGRAM - SOCK_RAW - vlan tag - qdisc bypass - bind() and sendto() - virtio_net_hdr - csum offload (NOT actual csum feature, ignored on loopback) - gso Besides these basic functionality tests, the test runs from a set of bounds checks, positive and negative.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2015-03-13selftests: Add install targetMichael Ellerman1-0/+1
This adds make install support to selftests.

The install destination is also configurable using eg: $ INSTALL_PATH=/mnt/selftests make install The implementation uses two targets in the child makefiles. The first "install" is expected to install all files into $(INSTALL_PATH). The second, "emit_tests", is expected to emit the test instructions (ie. bash script) on stdout. Separating this from install means the child makefiles need no knowledge of the location of the test script.

2015-03-13selftests: Introduce minimal shared logic for running testsMichael Ellerman1-4/+4
This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

TPACKET_V1: RX_RING, TX_RING TPACKET_V2: RX_RING, TX_RING TPACKET_V3: RX_RING ... and will output on success: test: TPACKET_V1 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V1 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_RX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V2 with PACKET_TX_RING .................... 100 pkts (9600 bytes) test: TPACKET_V3 with PACKET_RX_RING .................... 100 pkts (9600 bytes) OK. All tests passed Reusable parts of psock_fanout.c have been put into a psock_lib.h file for common usage. Test case successfully tested on x86_64.
