Hi, Starting here: http://fedoraproject.org/wiki/KernelRegressionTestGuidelines I grab the current test from git and run as root 'sh runtests.sh -t stress' and I experience the following, each of which is confusing so I don't know if it's expected behavior, or a bug, or what to do with this information if anything. The kernel is 4.4.0-1.fc24.x86_64, on otherwise updated Fedora 23 systems (an old Mac and a new NUC). 1. One system, dropcaches fails non-deterministically. I can't tell what the pattern is. When it fails the log reports: Starting test ./default/cachedrop 100+0 records in 100+0 records out 104857600 bytes (105 MB) copied, 0.0516614 s, 2.0 GB/s 10+0 records in 10+0 records out 10485760 bytes (10 MB) copied, 0.00891013 s, 1.2 GB/s TestError: Can't free dentries and inodes and pagecache 484736 484724 Could not run tests 2. The sysfs-perms test always fails on both systems: Starting test ./default/sysfs-perms Found world-writable files in sysfs. ./runtest.sh: line 9: ignore-files.sh: command not found 3. There are quit a few selinux AVC denials during the selinux DAC test, but at about the same time I also see these segfaults. Are they expected?

The stress test log file on both systems is 95M and the upload page won't accept that, so I take it only the minimal and default tests are uploadable and the stress test isn't something that's really interesting to the kernel team? The browser message when trying to upload is: Request Entity Too Large The data value transmitted exceeds the capacity limit. Even if it's bzip'd, it's 3+MB and that's still too big for the web interface. 5. fedora_submit.py fails: [chris@f23m kernel-tests]$ python fedora_submit.py -u chrismurphy -p pw -l logs/kernel-test-1452835548.log.txt Traceback (most recent call last): File "fedora_submit.py", line 45, in <module> password=password File "/usr/lib/python2.7/site-packages/fedora/client/openidbaseclient.py", line 283, in login openid_insecure=self.openid_insecure) File "/usr/lib/python2.7/site-packages/fedora/client/openidproxyclient.py", line 138, in openid_login raise AuthError(output['message']) fedora.client.AuthError: Authentication failed No idea what to do with that. Uploading this file (default sized) through the web interface does work. 6. Both systems skip the module signing test. Starting test ./default/modsign Module signing not enabled Could not run tests This makes sense on the EFI system that doesn't support secure boot, but the other one does. $ mokutil --sb-state SecureBoot enabled So... why is module signing not enabled? 7. The -t stress option, testing hasn't completed after 15+ hours on both systems, and both were unresponsive to local and remote login so I ended up hard resetting them. How long should it run and are there some tests where it's expected the system is unresponsive for more than an hour at a time? For one machine, the kernel-test log modification time was ~ 6 hours older than the time of the hard reset, so the system may have just locked up. Both journals are unrevealing, they lack any entries for those last 6 or more hours (I'm somewhat regularly hitting bug 1295612, so I've started running rsyslog as of today to see if it'll write out what's either not written to the journal or is getting corrupted and can't be viewed by journalctl). The last 10 lines of one kernel-test log look like this: ipcrm -m 720896 ipcrm -m 229377 ipcrm -m 917510 ipcrm -m 720896 ipcrm -m 229377 ipcrm -m 917510 ipc_str complete ipcrm -m 720896 ipcrm -m 229377 ipcrm -m 917510 Thanks, Chris Murphy _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/kernel@xxxxxxxxxxxxxxxxxxxxxxx
