Package: linux-libc-dev
Version: 2.6.32-46
The file /usr/include/linux/rfkill.h has the following declaration:
struct rfkill_event {
__u32 idx;
__u8 type;
__u8 op;
__u8 soft, hard;
} __packed;
However, __packed is not declared and this declaration is actually a
definition of both the struct rfkill_event and a variable __packed.
This causes problems in two ways:
- structure definition is not necessarily packed
- I got duplicate definitions of the __packed variable in some of my own
code
Package version 3.2.23-1~bpo60+2 which can be found in debian-backports
doesn't have this bug, there the correct __attribute__ ((packed)) is used.
Here is a trivial example:
$ cat test.c
#include <linux/rfkill.h>
$ gcc -c -o test.o test.c
$ nm test.o
0000000000000008 C __packed
