[Bug 2045560] Re: TCP memory leak, slow network (arm64)
@nklya The 6.5 and 6.8 based jammy kernels have received this patch as well. The 6.2 based jammy kernel is no longer supported so it will not be receiving these patches. The way that the jammy 6.5/6.8 kernels work are, they are backports of the newer series kernels. So, for noble (24.04) for example, the noble 6.8 kernel has been back ported to jammy and is the jammy 6.8 based kernel. So, when changes go in to the noble 6.8 kernel, they automatically make it into the jammy 6.8 kernel. So this was targeted to noble and mantic, with the understanding that the changes would end up in the jammy 6.8 and 6.5 based kernel backports. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2045560 Title: TCP memory leak, slow network (arm64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2045560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

some more testing and send these out for review.

[Bug 2045560] Re: TCP memory leak, slow network (arm64)
I've looked at this issue in some detail now. The initial memory leak was introduced in linux kernel version v6.0, and the fix was introduced in the v6.9 kernel version. This means that the 6.5, and 6.8 based ubuntu kernels will contain this memory leak. I will submit a fix for the generic 6.8, and generic 6.5 kernels so all ubuntu kernels will receive the fix. For reference: The commit that introduces this issue is 3cd3399dd7a84ada85cb839989cdf7310e302c7d https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=3cd3399dd7a84ada85cb839989cdf7310e302c7d And the commit I will be working with to provide the fix is the stable backport to the 6.8.y stable kernel which is: d2fa3493811ecd49f1581940111ccf475fa5cd38 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=d2fa3493811ecd49f1581940111ccf475fa5cd38 ** Package changed: linux-signed-aws-6.2 (Ubuntu) => linux (Ubuntu) ** Also affects: linux (Ubuntu Noble) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Mantic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Mantic) Status: New => Confirmed ** Changed in: linux (Ubuntu Mantic) Assignee: (unassigned) => Philip Cox (philcox) ** Changed in: linux (Ubuntu Noble) Assignee: (unassigned) => Philip Cox (philcox) ** Changed in: linux (Ubuntu Noble) Status: New => Confirmed ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2045560 Title: TCP memory leak, slow network (arm64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2045560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2061006] [NEW] aws: KVM and guest support for the PSCI SYSTEM_OFF2 (hibernate) call
Public bug reported: SRU Justification: [Impact] PSCI v1.3 adds support for SYSTEM_OFF2 which is analogous to ACPI S4 state. This will allow hosting environments to determine that a guest is hibernated rather than just powered off, and ensure that they preserve the virtual environment appropriately to allow the guest to resume safely (or bump the hardware_signature in the FACS to trigger a clean reboot instead). [Fix] This adds support for it to KVM, and to the guest hibernate code. https://lore.kernel.org/lkml/20240312135958.727765-1-dw...@infradead.org [Test Plan] AWS tested. [Where problems could occur] If the final spec of the PSCI v1.3 changes, there may be changes required to this patch series.

[Bug 2056475] [NEW] aws: Backport latest ENA driver in upstream Linux to enable IRQ moderation
Public bug reported: SRU Justification: [Impact] In Ubuntu AMIs for x86 and Graviton based EC2 instances, the standard Ubuntu AMI comes without IRQ moderation enabled for ENA, which for our latest generation instances with networking heavy workloads is up to a 25% performance regression (i.e. NGINX in a load-balancing configuration). [Fix] The mainline Linux kernel will now support IRQ moderation by default for ENA in the 6.9 kernel release via this patch: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/drivers/net/ethernet/amazon/ena?id=50d7a2660579889fba28b7e4543d4ce85aa2311b [Test Plan] AWS tested [Where problems could occur] By enabling adaptive coalescing, the default interrupt behaviour will by changed to be more adaptive, which shows improvements on heavy network workloads, but my change the behaviour and performance on other network workloads differently. Rather than handling the interrupts based off of a fixed amount of time elapsed, it will change to an adaptive based approach. There should be no negative impact on light workloads, and a positive impact on heavy work loads. If there is an impact though, this option can be disabled via the ethtool command.

[Bug 1962674] Re: Add IIO sensors ID for ACPI based platform
I have had to disable the ADXL345 accelerator driver in the jammy:linux- intel-iotg kernel. The code is broken, and needs a bit of work to correct. It was also broken in the 5.13 build, so it is not a regression. I know that it appeared to be enabled in the 5.13 config. but because of the Kconfig dependencies, it was actually disabled because it requires the ADXL34X module to be disabled. Only one can be enabled in the kernel. When I disable the 34X and enable the 345 driver, it fails because the function adxl345_i2c_remove() is not defined, but it is called. I am going to revert the change where CONFIG_ADXL345 is enabled. The build break will need to be corrected in both the 5.13 build, and the 5.15 build. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1962674 Title: Add IIO sensors ID for ACPI based platform To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1962674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1929894] Re: [TGL][EHL][ADL] Enable MEI (Intel Management Engine Interface)
@Sachin, Both the CONFIG_INTEL_MEI_DAL and CONFIG_INTEL_MEI_VIRTIO code paths have build breakages currently. I have not looked in to these failures too much yet, but the virtio one looks like missing function prototypes, or actually missing functions. This may be a patch is that is missing, or something has moved/renamed. The MEI_DAL one looks like the function pointer return type changed from "int" to "void". Looking at dal_remove(), I suspect changing the return type from int to void would be safe, but there I haven't found an upstream version of this code to compare with.
