Now fpu can be enabled in the whole softirq context. Unlike the old version, the new kernel raises softirq even in the boot phase, when fpu related stuff (such as registers or process fpu state) is not ready for manipulation (otherwise exception raised), so it should be enabled in the first kernel_fpu_begin() (i.e. the first possible crypto API call happens in the softirq context) instead of __do_softirq().

Send request from host to VM Backend is apache. Curl receives an html page from the server. tempesta_fw.conf log |

I've changed the patch little bit to test the fpu, in my case I can boot the system without any troubles. It would be great if other reviewers also apply this patch and test it. @krizhanovsky @biathlon3 @EvgeniiMekhanik Patch was applied to commit of the kernel 13f5dc9 and Tempesta: e95951a21ea4c445b37309f1f4d388428854fabb Files: diff.tar.gz |

@biathlon3 I cannot reproduce your errors in my env. What's your backend and did you run curl on the same machine? Did you enable selinux? If so, why? And, did you change the code? |
|
@kingluo My backend Apache. I run curl on the host, Tempesta on VM. I did not enable selinux specially, I will try to disable it. I got this bug with and without changes. |
Well, I could not reproduce it. Please make sure the test environment is clean, for example, create a new qemu VM instance and try to install the new kernel of my branch without making any changes. PS, before a final confirmation, I would rather say this is a suspected issue than a bug. |
