[Bug 1603719] Re: NFS client: access problems after updating to kernel 4.4.0-31-generic
I also tried Upstream v4.4.15 (35467dc7630af60abacc330f64029d081f160530) which does not have the issue. Going to bisect shortly. ** Summary changed: - NFS client: access problems after updating to kernel 4.4.0-31-generic + [regression] NFS client: access problems after updating to kernel 4.4.0-31-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1603719 Title: [regression] NFS client: access problems after updating to kernel 4.4.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for your helpful instructions. The most recent mainline kernel (= 4.7.0-040700rc7-generic) appears to be unaffected.

[Bug 1603719] Re: NFS client: access problems after updating to kernel 4.4.0-31-generic
Jurgen Schellaert, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results. Thank you for your understanding. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1603719 Title: NFS client: access problems after updating to kernel 4.4.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1603719] Re: NFS client: access problems after updating to kernel 4.4.0-31-generic
Same issue on this kernel. Cant browse subdirectories that are mounted hdds after kernel update. Downgrading fixes the issue. Ex can browse /mnt but cant browse /mnt/hdd1 /mnt/hdd2 etc If im root i can browse the subdirectories though just not as a standard user. Verified permission and works fine on a kernel downgrade. After root user has browsed a nfs subdirectory a standard user can browse it. Also able to browse the subdirectories if I mount each hdd individually. Ex if I mount on client /mnt/hdd1 instead of mounting /mnt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1603719 Title: NFS client: access problems after updating to kernel 4.4.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
