Bug #: 13144
Summary: Incorrect x86-64 bits/sem.h
Product: glibc
Version: 2.14
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: hjl.tools@gmail.com
Classification: Unclassified
sysdeps/unix/sysv/linux/x86_64/bits/sem.h has
/* Data structure describing a set of semaphores. */
struct semid_ds
{
struct ipc_perm sem_perm; /* operation permission struct */
__time_t sem_otime; /* last semop() time */
unsigned long int __unused1;
__time_t sem_ctime; /* last time changed by semctl() */
unsigned long int __unused2;
unsigned long int sem_nsems; /* number of semaphores in set */
unsigned long int __unused3;
unsigned long int __unused4;
};
But kernel include/asm-generic/sembuf.h has
struct semid64_ds {
struct ipc64_perm sem_perm; /* permissions .. see ipc.h */
__kernel_time_t sem_otime; /* last semop time */
#if __BITS_PER_LONG != 64
unsigned long __unused1;
#endif
__kernel_time_t sem_ctime; /* last change time */
#if __BITS_PER_LONG != 64
unsigned long __unused2;
#endif
unsigned long sem_nsems; /* no. of semaphores in array */
unsigned long __unused3;
unsigned long __unused4;
};
unused1 and unused2 fields should be protected with
#if __WORDSIZE == 32
#endif

x86_64 does not use the asm-generic version of semid64_ds. The correct
definition is in arch/x86/include/asm/sembuf.h.
