几个月前，我在我的两台机器上从 20.04 LTS 升级到了 22.04 LTS；我在 /boot 中看到了以下内容：

uname -r 返回：

6.8.0-52-generic

执行 sudo apt update 和 upgrade 时，版本 5.15 已更新（执行了 sudo apt autoremove 以删除旧版本，上面未显示）。知道为什么更新了这些内容吗？vmlinuz.old 指的是 6.8.0-52，但我当前的内核是 6.8.0-52？

我正在尝试将我的 jumphost 从 Ubutnu 20.04 升级到 Ubuntu 24.04.2 LTS，并启用审核。

这是我的会议：

$ cat /etc/audit/rules.d/000.audit.rules
-D
-b 64
-r 1000
-f 1

# Logging All user commands
-a always,exit -F arch=b64 -S execve -F auid>=1000 -F auid!=4294967295 -k user_commands
-a always,exit -F arch=b32 -S execve -F auid>=1000 -F auid!=4294967295 -k user_commands

...

但是当用户登录系统（40-70 个用户）时，我注意到系统会消耗所有 RAM，因为 RAM 的使用是内核缓冲区，这是由于速率限制而使用的，这会导致系统性能下降直至冻结

$ grep -E 'Slab|SReclaimable|SUnreclaim' /proc/meminfo && free -m
Slab:            2690568 kB
SReclaimable:      14672 kB
SUnreclaim:      2675896 kB
               total        used        free      shared  buff/cache   available
Mem:            2972        2961          70           0          56          10
Swap:           4521         467        4054

这在 Ubuntu 20 中不会发生。
有什么想法可以解决它吗？

感谢您的帮助。

我有一台 vanilla 24.04.2 机器，内核为 6.8.0-53-generic，我想启用 HWE

我尝试通过 apt 安装 hwe 内核

sudo apt install linux-generic-hwe-24.04

但是，构建失败，崩溃日志告诉我内核是由与我安装的 GCC 版本不同的版本构建的。但是，崩溃日志中列出的 GCC 版本是相同的。

The kernel was built by: x86_64-linux-gnu-gcc-13 (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
You are using:           gcc-13 (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0

具体的编译错误是

   CC [M]  /var/lib/dkms/xtrx/0.0.1+git20190320.5ae3a3e-3.2ubuntu2/build/xtrx.o
 /var/lib/dkms/xtrx/0.0.1+git20190320.5ae3a3e-3.2ubuntu2/build/xtrx.c: In function ‘xtrx_uart_do_tx’:

   472 |         xmit = &port->state->xmit;

看来我有正确的编译器：

今天，我尝试为运行 Ubuntu 24.04.2 LTS 的 PC 启用 Ubuntu Pro。一切顺利，直到无法在软件应用程序中启用 livepatch，并出现警告“Livepatch 不涵盖当前内核”。我发现对于 Ubuntu 24.04，唯一支持的内核是 6.8（低于我当前的内核 6.11）。我想知道 Livepatch 何时会在 Ubuntu 上覆盖内核版本 6.11，因为它提供的安全更新不需要重新启动即可安装。谢谢！

Ubuntu 24.04.2 LTS，戴尔公司 Latitude 7390，Intel® Core™ i5-8350U × 8 这是一份报告和问题。不久前，我的挂起系统突然唤醒。如果我离开它并自动挂起，或者我将其置于挂起状态，它都不会唤醒。我的研究表明这是一个相当常见的问题，并且通常是内核更新造成的。因此，我重新启动到最后一个内核，即 6.8.0-52.53-generic 6.8.12，挂起系统又开始工作了。我的问题是，这更有可能是因为我的笔记本电脑比较旧吗？它现在已经有 7 年的历史了。此外，我应该如何处理未来的内核更新？有什么理由不保留内核 6.8 吗？谢谢大家！

我一直在将Ubuntu 安全网站上提供的 CVE 数据与从相应 OVAL 文件中提取的信息进行比较。在分析 Jammy (22.04 LTS) 时，我注意到 OVAL 文件不包含对HWE 内核 6.8 的任何引用，尽管该内核已在网站上列出。

例如，在网站上，CVE-2024-38541指出：

linux-hwe-6.8 -> 22.04 LTS (Jammy) -> Fixed in 6.8.0-40.40~22.04.3

然而，在OVAL 文件中没有提到linux-hwe-6.8，而存在较旧的 HWE 内核，例如 linux-hwe-5.19、linux-hwe-6.2 和 linux-hwe-6.5：

<criteria operator="OR">
  <criterion test_ref="oval:com.ubuntu.jammy:tst:201245420000000" comment="Is kernel linux running?"/>
  <criterion test_ref="oval:com.ubuntu.jammy:tst:201245420000160" comment="Is kernel linux-hwe-5.19 running?"/>
  <criterion test_ref="oval:com.ubuntu.jammy:tst:201245420000270" comment="Is kernel linux-hwe-6.2 running?"/>
  <criterion test_ref="oval:com.ubuntu.jammy:tst:201245420000350" comment="Is kernel linux-hwe-6.5 running?"/>
  <criterion test_ref="oval:com.ubuntu.jammy:tst:201245420000050" comment="Is kernel linux-kvm running?"/>
  ...
</criteria>

这些信息缺失是不是出于某种原因？这可能是 OVAL 文件中的错误吗？我是不是忽略了什么？

任何见解都将不胜感激。提前致谢！

每次重启后，我都必须运行这个命令列表来释放我的处理器，避免其过载

我尝试将操作系统升级到最新版本 - 但无济于事

这是我的系统参数：

我想跟踪系统范围的跟踪点。Perf 列表告诉我以下跟踪点可用：

  block:block_io_start                               [Tracepoint event]
  block:block_plug                                   [Tracepoint event]

  block:block_rq_insert                              [Tracepoint event]

  power:cpu_idle_miss                                [Tracepoint event]

我知道我应该用

 perf record -e TRACEPOINT -a

用于系统范围的跟踪。但是，我被告知跟踪点是unsupported tracepoint：

perf record -e block:block_io_start -a      
event syntax error: 'block:block_io_start'
                     \___ unsupported tracepoint

libtraceevent is necessary for tracepoint support
Run 'perf list' for a list of valid events

我安装了所有libtraceevent*软件包。我的内核是：

6.8.0-45我目前正在尝试按照类似于此处提到的步骤编译自定义的 Ubuntu Jammy (22.04) HWE 内核版本。我正在对iwlwifi驱动程序应用一些补丁。

以下是我的分步过程：

  1. git clone git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/jammy && cd jammy
  2. git checkout Ubuntu-hwe-6.8-6.8.0-45.45_22.04.1
  3. git switch -c my_branch/6.8.0-45_iwl_patch
  4. 将我的更改应用到drivers/net/wireless/intel/iwlwifi/iwl-nvm-parse.c文件
  5. git add . && git commit -m "My commit message"
  6. cp /boot/config-$(uname -r) .config
  7. sed -i 's/CONFIG_LOCALVERSION=""/CONFIG_LOCALVERSION="-ricciolino"/g' .config
  8. make oldconfig
  9. fakeroot debian/rules clean
  10. fakeroot debian/rules binary-headers binary-generic

一切工作正常，直到第 10 步，我在构建过程中遇到以下错误：
