Patch-ID# 100671-04 Keywords: TLI hang panic assertion failed mbuf leak Synopsis: SunOS 4.1.2;4.1.3: TLI causes application program to hang and mbuf leak. Date: Jan/20/94 SunOS release: 4.1.2, 4.1.3 Unbundled Product: Unbundled Release: Topic: TLI patch BugId's fixed with this patch: 1059282 1094895 1111395 1148365 1148146 Changes incorporated in this version: 1148146 Architectures for which this patch is available: sun4, sun4c, sun4m Patches which may conflict with this patch: Files included with this patch: tcp_tli.o Problem Description: 1148146: while a TLI client is doing a t_getstate, the process will submit a job to TLI subsystem and sleeps in strdoioctl. This job is queued on the TLI service queue. If at this time, a disconnect request comes from the server, this t_getstate request will be flushed away from the job queue. Hence, the sleeping process will never be awakened. 1148365: Under SunOS 4.1.3, an mbuf leaking problem exists when running a TLI application. This causes the system to hang after a period of time. 1111395: Applications hang if printf() instead of write() is used via listen/nlsadmin. The problem is TLI subsystem does not handle certain IOCTL calls. It simply ignores them without generating a reply. 1094895: If tli device is open/closed back to back many times, the sending process will hang eventually. 1059282: If the customer's TLI server program issues an exit statement after sending out all messages, the client reboots with the following message when attempt to issue t_snd(): panic: assertion failed: q->q_next, file: ../../os/str_buf.c, line: 1707 Install Instructions: As root: # mv /sys/sun{4,4c,4m}/OBJ/tcp_tli.o /sys/sun{4,4c,4m}/OBJ/tcp_tli.o.FCS # cp sun{4,4c,4m}/{OS Level}/tcp_tli.o /sys/sun{4,4c,4m}/OBJ/tcp_tli.o rerun /etc/config and make and install the new kernel.
