I've lost track, but my guess is some / all of these need the unaligned_get_le32() etc rather than aligned form.

The unaligned accessors are fine > taking __le16 * for example. Ok my bad on using u16 here and I will change it. I 100% agree that these should be __le16/__le32. That said there is no need to use the unaligned accessors for the 16/32 bit fields. The unaligned accessors cast the pointer to a __le16/__le32 type and no architecture redefines those. So using le{16,32}_to_cpu() should work just fine on all archs.

I think the 16/32 bit fields work as intended except for my lack of using the correct type. Ira

So using le{16,32}_to_cpu() should work just > fine on all archs. If they are unaligned, make sure to use the unaligned accessors. Key is that it's not a simple cast, but rather a cast to a packed structure. The C spec guarantees that those will be handled correctly even on platforms that don't do unaligned accesses - it will have to use multiple instructions to construct the unaligned access from a set of small aligned ones. The C Spec doesn't guarantee the same for a simple cast to an __le16. There are some hints on this in: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/include/asm-generic/unaligned.h?id=778aaefb8e864fc61f850539ea479554dd4caea1 I recall a full explanation of why this worked, but no idea where to find that now - might be the thread referred to in that patch from Arnd.
