2024-04-13ktest: force $buildonly = 1 for 'make_warnings_file' test typeRicardo B. Marliere
[ Upstream commit 07283c1873a4d0eaa0e822536881bfdaea853910 ] The test type "make_warnings_file" should have no mandatory configuration parameters other than the ones required by the "build" test type, because its purpose is to create a file with build warnings that may or may not be used by other subsequent tests. Currently, the only way to use it as a stand-alone test is by setting POWER_CYCLE, CONSOLE, SSH_USER, BUILD_TARGET, TARGET_IMAGE, REBOOT_TYPE and GRUB_MENU.

2023-03-11ktest.pl: Add RUN_TIMEOUT option with default unlimitedSteven Rostedt
commit 4e7d2a8f0b52abf23b1dc13b3d88bc0923383cd5 upstream. There is a disconnect between the run_command function and the wait_for_input. The wait_for_input has a default timeout of 2 minutes. But if that happens, the run_command loop will exit out to the waitpid() of the executing command. This fails in that it no longer monitors the command, and also, the ssh to the test box can hang when its finished, as it's waiting for the pipe it's writing to to flush, but the loop that reads that pipe has already exited, leaving the command stuck, and the test hangs. Instead, make the default "wait_for_input" of the run_command infinite, and allow the user to override it if they want with a default timeout option "RUN_TIMEOUT". But this fixes the hang that happens when the pipe is full and the ssh session never exits.

2023-03-11ktest.pl: Fix missing "end_monitor" when machine check failsSteven Rostedt
commit e8bf9b98d40dbdf4e39362e3b85a70c61da68cb7 upstream. In the "reboot" command, it does a check of the machine to see if it is still alive with a simple "ssh echo" command. If it fails, it will assume that a normal "ssh reboot" is not possible and force a power cycle. In this case, the "start_monitor" is executed, but the "end_monitor" is not, and this causes the screen will not be given back to the console. That is, after the test, a "reset" command needs to be performed, as "echo" is turned off.

commit 83d29d439cd3ef23041570d55841f814af2ecac0 upstream. When monitoring the console output, the stdout is being redirected to do so. If Ctrl^C is hit during this mode, the stdout is not back to the console, the user does not see anything they type (no echo). Add "end_monitor" to the SIGINT interrupt handler to give back the console on Ctrl^C.

2023-01-18ktest.pl minconfig: Unset configs instead of just removing themSteven Rostedt
commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream. After a full run of a make_min_config test, I noticed there were a lot of CONFIGs still enabled that really should not be. Looking at them, I noticed they were all defined as "default y". The issue is that the test simple removes the config and re-runs make oldconfig, which enables it again because it is set to default 'y'. Instead, explicitly disable the config with writing "# CONFIG_FOO is not set" to the file to keep it from being set again. With this change, one of my box's minconfigs went from 768 configs set, down to 521 configs set.

2023-01-18kest.pl: Fix grub2 menu handling for rebootingSteven Rostedt
commit 26df05a8c1420ad3de314fdd407e7fc2058cc7aa upstream. grub2 has submenus where to use grub-reboot, it requires: grub-reboot X>Y where X is the main index and Y is the submenu. Thus if you have: menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ... [...] } submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ... menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ... [...] } And wanted to boot to the "Linux test" kernel, you need to run: # grub-reboot 1>2 As 1 is the second top menu (the submenu) and 2 is the third of the sub menu entries. Have the grub.cfg parsing for grub2 handle such cases.

2020-12-21ktest.pl: If size of log is too big to email, email error messageSteven Rostedt (VMware)
commit 8cd6bc0359deebd8500e6de95899a8a78d3ec4ba upstream. If the size of the error log is too big to send via email, and the sending fails, it wont email any result. This can be confusing for the user who is waiting for an email on the completion of the tests. If it fails to send email, then try again without the log file stating that it failed to send an email. Obviously this will not be of use if the sending of email failed for some other reasons, but it will at least give the user some information when it fails for the most common reason.

2020-12-16ktest.pl: Fix incorrect reboot for grub2blsLibo Chen
commit 271e0c9dce1b02a825b3cc1a7aa1fab7c381d44b upstream. This issue was first noticed when I was testing different kernels on Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a kernel entry was added successfully and the index of that kernel entry was retrieved correctly, ktest still wouldn't reboot the system into user-specified kernel. The bug was spotted in subroutine reboot_to where the if-statement never checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be set for the next boot. Add a check for "grub2bls" so that $grub_reboot $grub_number can be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to the correct kernel.

commit 4d00fc477a2ce8b6d2b09fb34ef9fe9918e7d434 upstream. Before rebooting the box, a "ssh sync" is called to the test machine to see if it is alive or not. But if the test machine is in a partial state, that ssh may never actually finish, and the ktest test hangs. Add a 10 second timeout to the sync test, which will fail after 10 seconds and then cause the test to reboot the test machine.

2018-04-06ktest: Add standalone config-bisect.pl programSteven Rostedt (Red Hat)
Started working on a stand alone program that can do a config bisect. It is based on the config bisect code of ktest.pl. Instead of needing all the infrastructure of ktest.pl, all that is required for config-bisect.pl is two config files. One that works, and one that does not. The goal is to pass in the two files, and it will create a new "good" and a new "bad" config file based on input from the user. After several iterations (calls to this program), it will eventually end with a minimum config value that allows one config to work and the other config to break. The program uses a technique that takes the good config and then makes half of the configs that differ from the bad config just like the bad config. The code will use make oldconfig to make sure the configs that are set are not all converted back due to incorrect dependencies on other configs set in the bad config but not in the new test config. This is still a work in progress, but as it was written while I was working at Red Hat, I want this code to be submitted as such. Signed-off-by: Steven Rostedt (Red Hat) <rostedt@goodmis.org>

2018-03-21ktest: Add CONNECT_TIMEOUT to change the connection timeout timeSteven Rostedt (VMware)
Before ktest issues a reboot, it will try to connect to the target machine to make sure that it is still alive. If the target does not respond within 5 seconds, it will power cycle the box instead of issuing a reboot. Five seconds may be too short, and ktest may unnecessarially power cycle the box. I have found 25 seconds seems to be a better timeout for this purpose. But even 25 may be too arbitrary. Add a CONNECT_TIMEOUT option to let the user determine the timeout time before rebooting. By default, it has been raised to 25 seconds. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2018-03-16arch: remove tile portArnd Bergmann
The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
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.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest Pull ktest fixes from Steven Rostedt: "Greg Kroah-Hartman reported to me that the ktest of v4.11-rc1 locked up in an infinite loop while doing the make mrproper. Looking into the cause I noticed that a recent update to the function run_command (used for running all shell commands, including "make mrproper") changed the internal loop to use the function wait_for_input. The wait_for_input function uses select to look at two file descriptors. One is the file descriptor of the command it is running, the other is STDIN. The STDIN check was not checking the return status of the sysread call, and was also just writing a lot of data into syswrite without regard to the size of the data read. Changing the code to check the return status of sysread, and also to still process the passed in descriptor data without looping back to the select fixed Greg's problem. While looking at this code I also realized that the loop did not honor the timeout if STDIN always had input (or for some reason return error). this could prevent wait_for_input to timeout on the file descriptor it is suppose to be waiting for. That is fixed too" * tag 'ktest-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest: ktest: Make sure wait_for_input does honor the timeout ktest: Fix while loop in wait_for_input
