[Kernel-packages] [Bug 1703742] [NEW] Transparent hugepages should default to enabled=madvise
Public bug reported: Ubuntu kernels should default transparent_hugepages to enabled=madvise, not enabled=always (this corresponds to TRANSPARENT_HUGEPAGE_MADVISE=y in .config). I've blogged about this at some length here: https://blog.nelhage.com/post/transparent-hugepages/ but here is a summary: Transparent Hugepages are a feature that allows the kernel to attempt to automatically back any anonymous maps with "huge" 2MiB page tables, instead of the normal 4k entries. It can produce small net performance gains in certain benchmarks, but also has numerous downsides, in the form of apparent memory leaks and 30% slowdowns or worse for some applications. Many popular pieces of software now refuse to run with hugepages enabled because of known performance issues.

[Kernel-packages] [Bug 1518457] Re: kswapd0 100% CPU usage
Some further debugging: On my t2.micro test case, the machine comes up with 9 memory devices, the last of which is offline at boot. Bringing that device online by hand (with the udev rules disabled) triggers the bug. # echo online > /sys/devices/system/memory/memory8/state So something about bringing that node online causes the problem. The udev bugfix causes udev to automatically bring it up, which is why that introduced the issue, but it doesn't seem like udev is really the root problem here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage Status in linux package in Ubuntu: In Progress Bug description: As per bug 721896 and various others: I'm on an AWS t2.micro instance (Xeon E5-2670, 991MiB of memory).

[Kernel-packages] [Bug 1518457] Re: kswapd0 100% CPU usage
I did some experimentation, and I can reproduce @oystein-gisnas's result that nuking that file from `/lib/udev/rules.d/` and rebooting fixes the issue. However, removing that file and restarting udev does *not* seem to fix the issue. So I suspect the problem is not with udev, but rather with some kernel feature that udev is enabling or toggling as part of processing that file. Also, as an aside, editing that file isn't a good workaround, since upgrading udev may clobber it again. If you instead create an `/etc/udev/rules.d/40-vm-hotadd.rules` containing the edited version, that file will take precedence over the one in `/lib`, and also be robust against udev upgrades. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage Status in linux package in Ubuntu: In Progress Bug description: As per bug 721896 and various others: I'm on an AWS t2.micro instance (Xeon E5-2670, 991MiB of memory).

[Kernel-packages] [Bug 1445664] Re: kernel 3.16 breaks POSIX extended ACLs over NFS
I may or may not have time to do the bisect any time soon, but based on some log-diving, I strongly suspect https://github.com/torvalds/linux/commit/013cdf1088d7235da9477a2375654921d9b9ba9f or the related refactors of being the commit that introduced this regression. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1445664 Title: kernel 3.16 breaks POSIX extended ACLs over NFS Status in linux package in Ubuntu: Incomplete Bug description: I have a development environment that uses Vagrant with NFS shares to a Trusty development VM from OS X laptops. After the upgrade to the HWE kernel 3.16, installing Ruby gems into the NFS mount inside the VM failed because of install(1) failing with permission errors.

After the upgrade to the HWE kernel 3.16, installing Ruby gems into the NFS mount inside the VM failed because of install(1) failing with permission errors. Debugging revealed that it's trying to set POSIX extended ACLs using setxattr(); On 3.13 this operation failed with EOPNOTSUPP (the server does not support extended ACLs), but on 3.16 it fails with EPERM, even if the NFS mount is explicitly mounted with "noacl". Debugging with ftrace and source diving suggests that kernel 3.16 refactored the POSIX extended ACL code so that before the call even hits the NFS layer, it passes through a generic permission-check layer. It appears that that layer is not aware of NFS UID remapping, and so fails the call regardless of what the server would have done. A simple test case is `install -c -m 0755 `, which will succeed on 3.13 and fail on 3.16. The broken system is: vagrant@packer-vmware-iso:~$ lsb_release -a; uname -a No LSB modules are available.

[Kernel-packages] [Bug 1445664] Re: kernel 3.16 breaks POSIX extended ACLs over NFS
apport information ** Tags added: apport-collected trusty ** Description changed: I have a development environment that uses Vagrant with NFS shares to a Trusty development VM from OS X laptops. After the upgrade to the HWE kernel 3.16, installing Ruby gems into the NFS mount inside the VM failed because of install(1) failing with permission errors. Debugging revealed that it's trying to set POSIX extended ACLs using setxattr(); On 3.13 this operation failed with EOPNOTSUPP (the server does not support extended ACLs), but on 3.16 it fails with EPERM, even if the NFS mount is explicitly mounted with "noacl". Debugging with ftrace and source diving suggests that kernel 3.16 refactored the POSIX extended ACL code so that before the call even hits the NFS layer, it passes through a generic permission-check layer. It appears that that layer is not aware of NFS UID remapping, and so fails the call regardless of what the server would have done.

Hi @ddstreet, thanks for the update. We unfortunately weren't able to reproduce this on your test kernel, and have since moved to a newer kernel version for other reasons. However, I can confirm that on the affected machine types, and only the affected machine type, we see a memory range in `/proc/iomem` that ends off of a multiple of 2M. Again, we do not see this on any other machines. I've attached `/proc/iomem` and `/proc/zoneinfo` from an affected machine (currently running an LTS backport kernel: Linux [redacted] 3.19.0-33-generic #38~14.04.1-Ubuntu SMP Fri Nov 6 18:17:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ) I'm pretty sure they show the kind of mismatch you're talking about; iomem shows 1-f0fffefff : System RAM f0000-f0fff : RAM buffer f1000-f17ff : System RAM But the “Node 0 Normal” zone, judging from (start_pfn, start_pfn+spanned) spans 1-f1800. The machine in question is a c4.8xlarge in EC2. ** Attachment added: "iomem.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1497428/+attachment/4529726/+files/iomem.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1497428 Title: kernel BUG at /build/buildd/linux-3.13.0/mm/page_alloc.c:968 Status in linux package in Ubuntu: In Progress Status in linux source package in Trusty: In Progress Bug description: The kernel triggers a BUG when it finds it is in move_freepages() but the start and end pfns for the move are in different zones.
