2020-11-30ktest.pl: Fix the logic for truncating the size of the log file for emailSteven Rostedt (VMware)1-7/+6
The logic for truncating the log file for emailing based on the MAIL_MAX_SIZE option is confusing and incorrect. Simplify it and have the tail of the log file truncated to the max size specified in the config.

2020-11-30ktest.pl: If size of log is too big to email, email error messageSteven Rostedt (VMware)1-1/+6
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.

2020-11-30ktest.pl: Fix incorrect reboot for grub2blsLibo Chen1-1/+1
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.

2020-07-01ktest.pl: Always show log file location if defined even on successSteven Rostedt (VMware)1-0/+4
If a log file is defined and the test were to error, a print statement is made that shows the user where the log file is to examine it further. But this is not done if the test were to succeed. I find it annoying that it does not show where the log file is on success, as I run several different tests that place their log files in various locations, and even though the test pass, there's things I want to look at in the log file (like warnings). It is much easier to find where the log file is, if it is displayed at the end of a test. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2020-07-01ktest.pl: Have config-bisect save each config used in the bisectSteven Rostedt (VMware)1-2/+8
When performing a automatic config bisect via ktest.pl, it is very useful to have a copy of each of the bisects used. This way, if a bisect were to go wrong, it is possible to retrace the steps and continue at the location before the error was made. The ktest.pl will make a copy of the good and bad configs, labeled as such, as well as a number attached to it that represents the iteration of the bisect. These files are saved in the ktest temp directory where it currently stores the good and bad config files. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2020-03-09ktest: Add timeout for ssh sync testingSteven Rostedt (VMware)1-1/+1
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.

2020-03-09ktest: Make default build option oldconfig not randconfigSteven Rostedt (VMware)2-2/+2
For the last time, I screwed up my ktest config file, and the build went into the default "randconfig", blowing away the .config that I had set up. The reason for the default randconfig was because when this was first written, I wanted to do a bunch of randconfigs. But as time progressed, ktest isn't about randconfig anymore, and because randconfig destroys the config in the build directory, it's a dangerous default to have. Use oldconfig as the default.

2018-04-06ktest.pl: Make finding config-bisect.pl dynamicSteven Rostedt (VMware)2-1/+36
Just looking for config-bisect.pl in the source tree can be risky, especially, if the source tree being tested doesn't have config-bisect.pl in place. Instead, allow the user to set where to find config-bisect.pl with a new option CONFIG_BISECT_EXEC. If this option is not set, by default, ktest.pl will look for config-bisect.pl in the following locations: `pwd`/config-bisect.pl # where ktest.pl was called from `dirname /path/to/ktest.pl`/config-bisect.pl # where ktest.pl exists ${BUILD_DIR}/tools/testing/ktest/config-bisect.pl # where config-bisect.pl exists in the source tree.

2018-04-06ktest.pl: Have ktest.pl pass -r to config-bisect.pl to reset bisectSteven Rostedt (VMware)2-8/+19
If config-bisect.pl sees that a config_bisect has already been started, it will ask on the command line if it should bisect or not. This will mess up running config_bisect from ktest.pl. Have ktest.pl pass in '-r' to config-bisect.pl and have config-bisect.pl recognize that to reset without asking. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-04-06ktest.pl: Use diffconfig if available for failed config bisectsSteven Rostedt (VMware)1-1/+5
Check to see if diffconfig is available and use that to diff the configs instead of using 'diff -u', as diffconfig produces much better output of kernel config files. It checks the source directory for the executable. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-04-06ktest.pl: Allow for the config-bisect.pl output to display to consoleSteven Rostedt (VMware)1-4/+12
When commands are run in ktest, they are only displayed in the ktest log file, but that is not sufficient for outputting the display for config bisects. The result of a config bisect is not shown. Add a way to display the output of "run_command" which is the subroutine used by ktest to execute commands. Use this feature to display the output of config-bisect.pl executions to see the progress as well as the result. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-04-06ktest: Use config-bisect.pl in ktest.plScott Wood1-222/+42
Reduce code duplication and take advantage of bisection logic improvements by calling config-bisect.pl. The output of make oldconfig is now copied directly to the desired file, rather than doing assign_configs+save_config, in order to preserve the ordering so that diffing the configs at the end will provide useful output.
