Remove the redundant and confusing fill_copy(). Also add copy_msg() check for error. In this case exit from the function have to be done instead of break, because further code interprets any error as EAGAIN. Also define copy_msg() for the case when CONFIG_CHECKPOINT_RESTORE is disabled. Signed-off-by:

Passing and checking of msgflg to free_copy() is redundant. This patch sets copy to NULL on declaration instead and checks for non-NULL in free_copy(). Note: in case of copy allocation failure, error is returned immediately. So no need to check for IS_ERR() in free_copy(). Signed-off-by:

Stanislav Kinsbursky authored
This patch is required for checkpoint/restore in userspace. c/r requires some way to get all pending IPC messages without deleting them from the queue (checkpoint can fail and in this case tasks will be resumed, so queue have to be valid). To achive this, new operation flag MSG_COPY for sys_msgrcv() system call was introduced. If this flag was specified, then mtype is interpreted as number of the message to copy. If MSG_COPY is set, then kernel will allocate dummy message with passed size, and then use new copy_msg() helper function to copy desired message (instead of unlinking it from the queue). Notes: 1) Return -ENOSYS if MSG_COPY is specified, but CONFIG_CHECKPOINT_RESTORE is not set. Signed-off-by:

Stanislav Kinsbursky authored
Add 3 new variables and sysctls to tune them (by one "next_id" variable for messages, semaphores and shared memory respectively). This variable can be used to set desired id for next allocated IPC object. By default it's equal to -1 and old behaviour is preserved. If this variable is non-negative, then desired idr will be extracted from it and used as a start value to search for free IDR slot. Notes: 1) this patch doesn't guarantee that the new object will have desired id. So it's up to user space how to handle new object with wrong id. 2) After a sucessful id allocation attempt, "next_id" will be set back to -1 (if it was non-negative).

The idea here is to move to a finer grained reset. In some cases we may not need reset every block, and in other cases we may not need to re-init the entire asic. Reviewed-by:
