[lwip-devel] [patch #5846] struct sockaddr_in has different alignment than struct sockaddr

[Simon Goldschmidt]

Follow-up Comment #2, patch #5846 (project lwip):

It's the whole struct which is unaligned. Casting a pointer from sockaddr_in
to sockaddr leads to a warning. In Linux, it's the way we have it, but in my
opinion, this would also lead to a warning, wouldn't it?

Using packed is not that good, I think: The struct is accessed byte by byte
(using GCC) although that's not necessary, because sockaddr is only used to
pass over sockaddr_in structs in lwIP. In other words, I think if the one is
packed, the other should be packed, also.

I know what I submitted does not look nice and I'm open to any other
solution, as long as I get rid of the warning!
