Bug 767992

Description of problem:

/usr/include/linux/netfilter/nfnetlink_log.h won't compile cleanly in userspace due to use of kernel type definitions.


Version-Release number of selected component (if applicable):

2.6.32


How reproducible:

Create file 'test.c' containing

#include </usr/include/linux/netfilter/nfnetlink_log.h>

and compile with 

gcc -c test.c

 
Actual results:

Compile errors with 

In file included from test.c:7:
/usr/include/linux/netfilter/nfnetlink_log.h:31: error: expected specifier-qualifier-list before ‘aligned_be64’


Expected results:

Header file should compile cleanly in userspace.


Additional info:

Later kernels use a different typedef and define it in 'types.h'.

"nfnetlink_log.h"

struct nfulnl_msg_packet_timestamp {
	__aligned_be64	sec;
	__aligned_be64	usec;
};


"types.h"

/*
 * aligned_u64 should be used in defining kernel<->userspace ABIs to avoid
 * common 32/64-bit compat problems.
 * 64-bit values align to 4-byte boundaries on x86_32 (and possibly other
 * architectures) and to 8-byte boundaries on 64-bit architetures.  The new
 * aligned_64 type enforces 8-byte alignment so that structs containing
 * aligned_64 values have the same alignment on 32-bit and 64-bit architectures.
 * No conversions are necessary between 32-bit user-space and a 64-bit kernel.
