[Bug 1881631] Re: arm64 Ubuntu kernel builds missing CONFIG_NLS_ASCII

[Brent DeGraaf]

So is it now changed to 'y'?  Last night I confirmed that the module is
missing in initrd.img and that is what was causing the mount error, so
this is great news.

[Bug 1881631] Re: arm64 Ubuntu kernel builds missing CONFIG_NLS_ASCII

[Hui Wang]

** Description changed:

+ The CONFIG_NLS_ASCII was already set to Y in the raspi-5.4 kernel
+ and bionic kernel by Juerg, now do the same change in the
+ raspi2-5.3 kernel.
+ 
+ [Impact]
+ users reported that the raspi ubuntu core has some problem to mount
+ filessytem, need to enable the NLS_ASCII and make it built-in.
+ 
+ [Fix]
+ change it from m to y just as the focal and bionic raspi kernel.
+ 
+ [Test Case]
+ building the kernel and boot the kernel, it could mount the
+ filesystem successfully.
+ 
+ [Regression Risk]
+ Low, just changing a kconfig to y from m.
+ 
+ 
  Remounting log mounts in Ubuntu core are failing on arm64 builds due to 
missing CONFIG_NLS_ASCII in the arm64 kernel build options.
  This option is enabled on the other kernel builds but somehow was overlooked 
on arm64 appears to affect our ability to access logs via journalctl with data 
from prior to restart because certain mounts are failing.
  Other Raspberry Pi kernel builds, such as the armhf build, have the option 
enabled and so do not encounter the mount error.
  The kernel option that needs to be turned on to resolve this is 
CONFIG_NLS_ASCII. It needs to be set to either 'm' or 'y'. Most of the other 
chips have it set to 'y', keeping it built-in.

[Bug 1881631] Re: arm64 Ubuntu kernel builds missing CONFIG_NLS_ASCII

[Hui Wang]

ubuntu raspi-5.3 kernel (both armhf and arm64) set this config to m
while ubutnu raspi-5.4 kernel set it to y. Maybe the initrd of ubuntu
core doesn't contain nls_ascii.ko, so we need to set it to y in the
raspi-5.3 too?

I opened this bug report on behalf of @brentk4 from a support ticket.
Please refer to the kernel that referenced in #4.

Just to make sure that it was not my comment that misled you, I am not
aware of any currently fixed version.

[Francis Ginther]

@arbell,

Do you have the specific kernel and version you observed this on? A
`uname -a` or `dmesg` log would be sufficient. Based on some of the
comments here, the config value may have changed between versions so I
want to make sure we have the failing one identified correctly.

Re: [Bug 1881631] Re: arm64 Ubuntu kernel builds missing CONFIG_NLS_ASCII

[Brent DeGraaf]

Perhaps looking backward from this Raspberry pi kernel will help locate the
issue, which was definitely present in the build below:

5.3.0-1026-raspi2 #28~18.04.1-Ubuntu SMP Thu May 21 14:48:58 UTC 2020
aarch64 aarch64 aarch64 GNU/Linux

The final kernel that was getting built on arm64 did not have the flag set
on that tag.  The same flag is notably absent in the arm64 defconfig, which
appears to be what was used judging from the buildlog output I was able to
see searching on that tag.  If this was very recently fixed, we haven't
received a snap refresh as of yet.
