	PHKL_13611: HANG

Path Name: /hp-ux_patches/s700/10.X/PHKL_17359

Symptoms:
	PHKL_17359:
	(SR:5003444307 DTS:JAGaa44276)
	User processes which pass an invalid message ID to the
	msgsnd(), msgrcv() or msgctl() system calls may hang.

	PHKL_13611:
	SR:1653231340 DTS:DSDe439913
	The message queue intermittently hangs.

Defect Description:
	PHKL_17359:
	(SR:5003444307 DTS:JAGaa44276)
	The message queue ID passed into the system call was not
	validated before calling msgconv(), where it is used for the
	lookup of an array element. Under some conditions, it was
	possible for the calling process to be put to sleep on an
	invalid wait channel, which would never be sent the wakeup()
	needed to make the process runnable. The priority at which
	the thread sleeps means it is uninterruptible and hence
	cannot be terminated by sending a SIGKILL.
	Resolution:
	Validate the message queue ID passed in by the user program,
	returning EINVAL if the ID does not match the entry in the
	message queue table, before calling msgconv().

	PHKL_13611:
	SR:1653231340 DTS:DSDe439913
	One call to a function taking three parameters provided only
	two of those parameters.
