Hello Ratchanan, or anyone else affected, Accepted zfs-linux into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/zfs- linux/0.8.3-1ubuntu12.8 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: zfs-linux (Ubuntu Focal) Status: New => Fix Committed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1919252 Title: zfs-dkms on Focal still allows building on Linux kernel version 5.10+ Status in zfs-linux package in Ubuntu: In Progress Status in zfs-linux source package in Focal: Fix Committed Bug description: == SRU update, zfs-dkms, Focal == [Impact] Due to a mistake in the BUILD_EXCLUSIVE_KERNEL regex in dkms.conf, dkms will still consider zfs-dkms to be buildable on kernel version 5.10+. This can happen if one installs a mainline kernel from the mainline PPA for one reason or another. Fixing this will stop users from installing incompatible newer versions of the kernel and hence stop dkms build failures on known incompatible kernel versions. The fix is also trivial. [The Fix] Correctly escape . in regex so that the final sed'd string gets modified to produce the correct regex pattern, as follows: sed -ie '/^PACKAGE_VERSION/a BUILD_EXCLUSIVE_KERNEL="^(4\\.[0-9]+|5\\.[01234])\\."' \ '$(CURDIR)/scripts/zfs-dkms.dkms' [Test Plan] Without the fix, install kernels > than versions 5.4. ZFS dkms will attempt to be built against these and fail with broken builds. Installing earlier kernels such as 4.20, 5.0, 5.4 should succeed. With the fix, installing kernels > 5.4 will skip the ZFS dkms build phase and report a meaningful error: Error! The /var/lib/dkms/zfs/0.8.3/5.5.19-050519-generic/x86_64/dkms.conf for module zfs includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch. This indicates that it should not be built Test kernels for the test from https://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D can be used to test this out. [Where problems could occur] The change is to a regex pattern match. If this is incorrect then kernels such a 5.4 will not be allowed to build the dkms zfs driver. This will clearly show up as a ZFS dkms build denied failure with an error such as: Error! The /var/lib/dkms/zfs/0.8.3/5.5.19-050519-generic/x86_64/dkms.conf for module zfs includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch. This indicates that it should not be built This fix is relatively low-risk, it fixes am issue with an earlier fix to the regex which wasn't quite working for kernels > 5.4 and yet didn't cause any major issues blocking legitimate users from using known working 5.4 kernels with zfs dkms. ----------------------------------------------------------------------- Due to a mistake in the BUILD_EXCLUSIVE_KERNEL regex in dkms.conf, dkms will still consider zfs-dkms to be buildable on kernel version 5.10+. This can happen if one installs a mainline kernel from the mainline PPA for one reason or another [1].
