apport information
** Tags added: apport-collected
** Description changed:
Please apply commit df91e494 "TOMOYO: Fix mount flags checking order." which
is
in linux-next.git and will be included in 3.4-rc1. Without this patch, when
security=tomoyo is given to kernel boot parameter, certain combination of
mount
request cannot be granted.
Test case:
Compile test.c and run it as root.
----- test.c start -----
#include <stdio.h>
#include <string.h>
#include <sys/mount.h>
#include <errno.h>
int main(int argc, char *argv[])
{
if (mount(NULL, "/tmp", "tmpfs", 0, NULL))
return 1;
if (mount(NULL, "/tmp", NULL, MS_BIND | MS_REMOUNT, NULL) == 0)
printf("OK: Success.\n");
else
printf("BUG: %s\n", strerror(errno));
umount("/tmp");
return 0;
}
----- test.c end -----
Expected result:
OK: Success.
Actual result:
BUG: No such file or directory
