Description of problem: I have an unsupported Windows application (Unit Manager Express) that always worked fine. I don't use it often, maybe once a week or less. All of the sudden, it stopped launching. Not sure if it was a new Fedora kernel or the upgrade to 6.0.0 that broke it. I have tried uninstalling/reinstalling CrossOver and Unit Manager Express, but it still won't launch. I can provide the Unit Manager Express installation package. I booted with the previous kernel (2.6.18-1-2869.fc6.x86_64) and UME works again. It was running 2.6.19-1-2895.fc6.x86_64. From Codeweavers: "Please report this issue to the Fedora developers. If they need any feedback from me put this ticket in the bug report as well as my email address steven" Version-Release number of selected component (if applicable): How reproducible: Update kernel from 2.6.18-1-2869.fc6.x86_64 to 2.6.19-1-2895.fc6.x86_64 Steps to Reproduce: 1. Install CrossOver 6.0.0 2. Install Unit Manager Express 3. Update kernel to 2.6.19-1-2895.fc6.x86_64 Actual results: Expected results: Additional info:
Do any messages appear in the syslog when you try to run the app?
Created attachment 147564 [details] syslog running 2.6.18 (good)
Created attachment 147565 [details] syslog running 2.6.19 (bad)
I have attached syslog messages while launching Unit Manager Express under both 2.6.18 and 2.6.19. App loaded OK under 2.6.18, didn't launch at all under 2.6.19. - Bill
it's surprising it works at all with those SELinux denials (or are you in non-enforcing mode?) does booting with exec-shield=0 make any difference ? (Also give the 2.6.20 kernel from updates-testing a shot)
I know what caused this. Previous kernels returned -ENOTTY (IOCTL not available) when trying Windows IOCTLs on native Linux filesystems. David Howells's patch allowing network filesystems without CONFIG_BLOCK also changed the behavior of ioctl() so it now returns -EINVAL. This causes applications to error out because they get a return they don't expect.
