When CONFIG_KASAN is enabled but CONFIG_KASAN_VMALLOC
is not enabled, we may encounter a panic during system boot.
Because we haven't allocated pages and created mappings
for the shadow memory corresponding to module_tags region,
similar to how it is done for execmem_vmalloc.
The difference is that our module_tags are allocated on demand,
so similarly,we also need to allocate shadow memory regions on demand.
However, we still need to adhere to the MODULE_ALIGN principle.
Hello,
I applied this patch:
https://lore.kernel.org/all/20241130001423.1114965-1-surenb@xxxxxxxxxx/raw
as well as the v2 patch in this email thread, on top of today's Linus
kernel (plus local patches that should be un-related to this particular
issue) and now my system boots when my current mix of kernel debugging is enabled.
Thanks for the fix!
