[Buildroot] [PATCH 1/3] support/testing: bump prebuilt kernel to 5.10.202

[Yann E. MORIN]

Romain, All,

On 2023-12-06 23:44 +0100, Romain Naour spake thusly:
> As reported on the mailing list [1], TestPolkitSystemd and
> TestPolkitInitd are failing since we bumped the Bootlin toolchain
> 2023.08 [2].
> 
> The issue is caused by expat (XML library) package detecting
> arc4random_buf() introduced by glibc 2.36 [3].
> 
> With arc4random_buf() support enabled, expat hang Polkit while reading
> its policy files (XML files) due to a lack of entropy on the system.
> 
> Upgrading the kernel allows to avoid such issue thanks to
> random_get_entropy_fallback() introduced in 5.10.119 (backpored) [4].
> 
> Build the vexpress-v2p-ca9 (armv7) 5.10.202 using the kernel
> configuration file found in /proc/config.gz but with additional kernel
> options provided by SYSTEMD_LINUX_CONFIG_FIXUPS. Indeed some kernel
> options requested by systemd were missing in 5.10.7 kernel.
> 
> Build the versatile-pb (armv5) kernel using the same kernel
> configuration as qemu_arm_versatile_defconfig but with additional
> kernel options like for vexpress-v2p-ca9. While at it, enable
> IKCONFIG_PROC option to provide the kernel configuration at runtime
> in /proc/config.gz.
> 
> Runtime tested:
> https://gitlab.com/kubu93/buildroot/-/pipelines/1097887826 (tests.package.test_polkit.TestPolkit*)
> https://gitlab.com/kubu93/buildroot/-/pipelines/1097705399 (tests.init.*)
> 
> Fixes:
> https://gitlab.com/buildroot.org/buildroot/-/jobs/5689309948 (TestPolkitSystemd)
> https://gitlab.com/buildroot.org/buildroot/-/jobs/5689309947 (TestPolkitInitd)
