In particular the original code failed to - * wake up processes that were waiting for semval to go to 0 if the - * value went to 0 and was then incremented rapidly enough. In solving - * this problem I have also modified the implementation so that it - * processes pending operations in a FIFO manner, thus give a guarantee - * that processes waiting for a lock on the semaphore won't starve - * unless another locking process fails to unlock. - * In addition the following two changes in behavior have been introduced: - * - The original implementation of semop returned the value - * last semaphore element examined on success. This does not - * match the manual page specifications, and effectively - * allows the user to read the semaphore even if they do not - * have read permissions. The implementation now returns 0 - * on success as stated in the manual page. - * - There is some confusion over whether the set of undo adjustments - * to be performed at exit should be done in an atomic manner. - * That is, if we are attempting to decrement the semval should we queue - * up and wait until we can do so legally? - * The original implementation attempted to do this. - * The current implementation does not do so. This is because I don't - * think it is the right thing (TM) to do, and because I couldn't - * see a clean way to get the old behavior with the new design. - * The POSIX standard and SVID should be consulted to determine - * what behavior is mandated. - */ - -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include - -extern int ipcperms (struct ipc_perm *ipcp, short semflg); -static int newary (key_t, int, int); -static int findkey (key_t key); -static void freeary (int id); - -static struct semid_ds *semary[SEMMNI]; -static int used_sems = 0, used_semids = 0; -static struct wait_queue *sem_lock = NULL; -static int max_semid = 0; - -static unsigned short sem_seq = 0; - -void sem_init (void) -{ - int i; - - sem_lock = NULL; - used_sems = used_semids = max_semid = sem_seq = 0; - for (i = 0; i < SEMMNI; i++) - semary[i] = (struct semid_ds *) IPC_UNUSED; - return; -} - -static int findkey (key_t key) -{ - int id; - struct semid_ds *sma; - - for (id = 0; id <= max_semid; id++) { - while ((sma = semary[id]) == IPC_NOID) - interruptible_sleep_on (&sem_lock); - if (sma == IPC_UNUSED) - continue; - if (key == sma->sem_perm.key) - return id; - } - return -1; -} - -static int newary (key_t key, int nsems, int semflg) -{ - int id; - struct semid_ds *sma; - struct ipc_perm *ipcp; - int size; - - if (!nsems) - return -EINVAL; - if (used_sems + nsems > SEMMNS) - return -ENOSPC; - for (id = 0; id < SEMMNI; id++) - if (semary[id] == IPC_UNUSED) { - semary[id] = (struct semid_ds *) IPC_NOID; - goto found; - } - return -ENOSPC; -found: - size = sizeof (*sma) + nsems * sizeof (struct sem); - used_sems += nsems; - sma = (struct semid_ds *) kmalloc (size, GFP_KERNEL); - if (!sma) { - semary[id] = (struct semid_ds *) IPC_UNUSED; - used_sems -= nsems; - wake_up (&sem_lock); - return -ENOMEM; - } - memset (sma, 0, size); - sma->sem_base = (struct sem *) &sma[1]; - ipcp = &sma->sem_perm; - ipcp->mode = (semflg & S_IRWXUGO); - ipcp->key = key; - ipcp->cuid = ipcp->uid = current->euid; - ipcp->gid = ipcp->cgid = current->egid; - sma->sem_perm.seq = sem_seq; - /* sma->sem_pending = NULL; */ - sma->sem_pending_last = &sma->sem_pending; - /* sma->undo = NULL; */ - sma->sem_nsems = nsems; - sma->sem_ctime = CURRENT_TIME; - if (id > max_semid) - max_semid = id; - used_semids++; - semary[id] = sma; - wake_up (&sem_lock); - return (unsigned int) sma->sem_perm.seq * SEMMNI + id; -} - -asmlinkage int sys_semget (key_t key, int nsems, int semflg) -{ - int id, err = -EINVAL; - struct semid_ds *sma; - - lock_kernel(); - if (nsems < 0 || nsems > SEMMSL) - goto out; - if (key == IPC_PRIVATE) { - err = newary(key, nsems, semflg); - } else if ((id = findkey (key)) == -1) { /* key not used */ - if (!(semflg & IPC_CREAT)) - err = -ENOENT; - else - err = newary(key, nsems, semflg); - } else if (semflg & IPC_CREAT && semflg & IPC_EXCL) { - err = -EEXIST; - } else { - sma = semary[id]; - if (nsems > sma->sem_nsems) - err = -EINVAL; - else if (ipcperms(&sma->sem_perm, semflg)) - err = -EACCES; - else - err = (int) sma->sem_perm.seq * SEMMNI + id; - } -out: - unlock_kernel(); - return err; -} - -/* Manage the doubly linked list sma->sem_pending as a FIFO: - * insert new queue elements at the tail sma->sem_pending_last. - */ -static inline void insert_into_queue (struct semid_ds * sma, struct sem_queue * q) -{ - *(q->prev = sma->sem_pending_last) = q; - *(sma->sem_pending_last = &q->next) = NULL; -} -static inline void remove_from_queue (struct semid_ds * sma, struct sem_queue * q) -{ - *(q->prev) = q->next; - if (q->next) - q->next->prev = q->prev; - else /* sma->sem_pending_last == &q->next */ - sma->sem_pending_last = q->prev; - q->prev = NULL; /* mark as removed */ -} - -/* Determine whether a sequence of semaphore operations would succeed - * all at once.
