Turning COMPAT_32BIT_TIME off on riscv64

[Dimitri John Ledkov]

This will prevent (?!) binaries to operate correctly, if they are still using time32.... but maybe riscv32 ABI uses 64-bit time_t anyway?

24.04 LTS is likely to be used for 10 years. And if allowed to overrun and remain active in the field in 2038 can lead to catastrophic failure in the field due to these syscalls enabled and used.

I would like to request if we can turn off COMPAT_32BIT_TIME on every architecture, thus this will be arch by arch bug report, and arch by arch decision.

This needs to be a per-arch decision, potentially taking into consideration bi-arch userspace support.

config COMPAT_32BIT_TIME
 bool "Provide system calls for 32-bit time_t"
 default !64BIT || COMPAT
 help
   This enables 32 bit time_t support in addition to 64 bit time_t support.
   This is relevant on all 32-bit architectures, and 64-bit architectures
   as part of compat syscall handling.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2038584

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Consensus from maintainers is that it's a mistake that this option is on for riscv64, especially since compat is off.
