Fedora 26 kernel 4.18.7

Post by rolandp »

Hi,
My kernel has just been updated to 4.18.7 and now veeamsnap won't build :(
Here is my build log:

Code: Select all

Any ideas? Obviously I can roll back to 4.17 in the mean time...

Thanks,
Roland.

Hi,

Unfortunately the current version (2.0.1.665) supports Fedora only up to version 4.16.

Thanks.

Thanks for the confirmation. Is there an ETA for a build that does support more recent kernels?

in v4.18 kernel-space API changed and bioset_create()/bioset_free() were dropped, here is the commit
https://github.com/torvalds/linux/commi ... f94bc5e9b3

if you are curious about the fix, it is rather easy, you can use this
https://github.com/rustylife/veeamsnap/ ... 8a3e7c6afc

but my recommendation would be to wait for an official veeamsnap update

Re: Fedora 28 kernel 4.18.7

Post by rolandp »

Hmm, maybe not so easy after all :(
I downloaded the 3 changed source files and tried to rebuild, but it fails. It looks like it is for version 2.0.0.400 rather than 2.0.1.665? Is that correct or am I just seeing an old label somewhere?
BTW, originally I said Fedora 26, but it's actually Fedora 28. Not sure it makes any difference...

patch in my forked veeamsnap repo is indeed for 2.0.0.400 (veeamsnap repo maintainer did not push the latest version of the driver to github)
if you want to apply the patch to 2.0.1.665 code base you need to use "git apply" or "patch" commands, you cannot just copy modified files, you need to merge the patch

Hi rkovhaev,
thanks for the patch, it did build fine with 4.18.14-200 x86_64.
