1fix libcap header issue on some distro
2
31, When build qemu-native on SLED 11.2, there is an error:
4...
5| In file included from /usr/include/bits/sigcontext.h:28,
6| from /usr/include/signal.h:339,
7| from /buildarea2/tmp/work/i686-linux/qemu-native/1.4.0-r0/
8qemu-1.4.0/include/qemu-common.h:42,
9| from fsdev/virtfs-proxy-helper.c:23:
10| /usr/include/asm/sigcontext.h:28: error: expected specifier-
11qualifier-list before '__u64'
12| /usr/include/asm/sigcontext.h:191: error: expected specifier-
13qualifier-list before '__u64'
14...
15
162, The virtfs-proxy-helper.c includes <sys/capability.h> and
17qemu-common.h in sequence. The header include map is:
18(`-->' presents `include')
19...
20"virtfs-proxy-helper.c" --> <sys/capability.h>
21...
22"virtfs-proxy-helper.c" --> "qemu-common.h" --> <signal.h> -->
23<bits/sigcontext.h> --> <asm/sigcontext.h> --> <linux/types.h> -->
24<asm/types.h> --> <asm-generic/types.h> --> <asm-generic/int-ll64.h>
25...
26
273, The bug is found on SLED 11.2 x86. In libcap header file
28/usr/include/sys/capability.h, it does evil stuff like this:
29...
30 25 /*
31 26 * Make sure we can be included from userland by preventing
32 27 * capability.h from including other kernel headers
33 28 */
34 29 #define _LINUX_TYPES_H
35 30 #define _LINUX_FS_H
36 31 #define __LINUX_COMPILER_H
37 32 #define __user
38 33
39 34 typedef unsigned int __u32;
40 35 typedef __u32 __le32;
41...
42This completely prevents including /usr/include/linux/types.h.
43The above `<asm/sigcontext.h> --> <linux/types.h>' is prevented,
44and '__u64' is defined in <asm-generic/int-ll64.h>.
45
464, Modify virtfs-proxy-helper.c to include <sys/capability.h>
47last to workaround the issue.
