| Summary | 0005050: net: unaligned copying of unsigned long | ||||
| Description | net: unaligned copying of unsigned long The inline functions net_read_u32() and net_copy_u32() have been created to copy unaligned u32. But this is not obvious to the compiler. GCC 9.1 introduces a check -Werror=address-of-packed-member which leads to a build error on Travis CI: | ||||
