The panics are seen when the signalling and ILMI connections to the ATM switch are lost, for example when the switch fails, or when the fiber-optic link is disconnected. The problem is most likely to occur when the there is heavy ATM traffic from the system, such that re-connections are being attempted frequently. The patch also adds a backoff mechanism which moderates the rate at which ATM reconnections are attempted for Classical IP (RFC 1577) networks. This prevents the ATM switch from being continuously bombarded with requests. Three representative panic stack traces are shown below: 0 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2342] 1 panic("thread_block: simple lock owned") ["../../../../src/kernel/bsd/subr_prf.c":707] 2 thread_block() ["../../../../src/kernel/kern/sched_prim.c":1847] 3 thread_preempt() ["../../../../src/kernel/kern/sched_prim.c":3704] 4 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2286] 5 panic("kernel memory fault") ["../../../../src/kernel/bsd/subr_prf.c": 791] 6 trap() ["../../../../src/kernel/arch/alpha/trap.c":1457] 7 _XentMM() ["../../../../src/kernel/arch/alpha/locore.s":1388] 8 malloc() ["../../../../src/kernel/bsd/kern_malloc.c":871] 9 atmip_new_ppa() ["../../../../src/kernel/netinet/atm/ip_converge.c":1585] 10 atmip_exception() ["../../../../src/kernel/netinet/atm/ip_converge.c":779] 11 atm_cmm_ppa_tell() ["../../../../src/kernel/atm/cmm/cmm_ppa.c":537] 12 atm_cmm_new_ppa() ["../../../../src/kernel/atm/cmm/cmm_ppa.c":366] 13 fsm_set_response_rcvd() ["../../../../src/kernel/atm/uni3.x/ilmi/fsm.c":1169] 14 proc_resp() ["../../../../src/kernel/atm/uni3.x/ilmi/agent.c":1369] 15 agent_parse() ["../../../../src/kernel/atm/uni3.x/ilmi/agent.c":343] 16 atm_ilmi_process_receive() ["../../../../src/kernel/atm/uni3.x/ilmi/agent.c":191] 17 atm_sig_event_process() ["../../../../src/kernel/atm/uni3.x/cmmintf/qsaal_converge.c":1136] 0 stop_secondary_cpu() ["../../../../src/kernel/arch/alpha/cpu.c":488] 1 panic("event_timeout: panic request") ["../../../../src/kernel/bsd/subr_prf.c":703] 2 event_timeout() ["../../../../src/kernel/arch/alpha/cpu.c":979] 3 xcpu_puts() ["../../../../src/kernel/bsd/subr_prf.c":844] 4 printf() ["../../../../src/kernel/bsd/subr_prf.c":379] 5 panic("kernel memory fault") ["../../../../src/kernel/bsd/subr_prf.c":753] 6 trap() ["../../../../src/kernel/arch/alpha/trap.c":1457] 7 _XentMM() ["../../../../src/kernel/arch/alpha/locore.s":1392] 8 atm_cmm_release_vc() ["../../../../src/kernel/atm/cmm/cmm_cmi.c":927] 9 atm_cmm_con_release() ["../../../../src/kernel/atm/cmm/cmm_smi.c":938] 10 atm_sig_release_all_calls() ["../../../../src/kernel/atm/uni3.x/cmmintf/q93b_sig.c":3016] 11 AmUiAmtRstInd() ["../../../../src/kernel/atm/uni3.x/cmmintf/q93b_sig.c":2885] 12 amComTCON() ["../../../../src/kernel/atm/uni3.x/q93b/am_bdy2.c":3517] 13 amCbTmrExpiry() ["../../../../src/kernel/atm/uni3.x/q93b/am_bdy3.c":775] 14 cmPrcTmr() ["../../../../src/kernel/atm/uni3.x/common/cm_bdy5.c":180] 15 amActvTmr() ["../../../../src/kernel/atm/uni3.x/q93b/am_bdy1.c":4286] 16 schedule_sig_timers() ["../../../../src/kernel/atm/uni3.x/common/ss_ptsp.c":3651] 0 stop_secondary_cpu() ["../../../../src/kernel/arch/alpha/cpu.c":414] 1 panic("event_timeout: panic request") ["../../../../src/kernel/bsd/subr_prf.c":703] 2 event_timeout() ["../../../../src/kernel/arch/alpha/cpu.c":811] 3 xcpu_puts() ["../../../../src/kernel/bsd/subr_prf.c":844] 4 printf() ["../../../../src/kernel/bsd/subr_prf.c":379] 5 panic("kernel memory fault") ["../../../../src/kernel/bsd/subr_prf.c":753] 6 trap() ["../../../../src/kernel/arch/alpha/trap.c":1457] 7 _XentMM() ["../../../../src/kernel/arch/alpha/locore.s":1388] 8 atmip_make_call() ["../../../../src/kernel/netinet/atm/ip_converge.c":2004] 9 atmip_output() ["../../../../src/kernel/netinet/atm/ip_converge.c":445] 10 ip_output() ["../../../../src/kernel/netinet/ip_output.c":616] 11 rip_output() ["../../../../src/kernel/netinet/raw_ip.c":240] 12 raw_usrreq() ["../../../../src/kernel/net/raw_usrreq.c":338] 13 rip_usrreq() ["../../../../src/kernel/netinet/raw_ip.c":435] 14 sosend() ["../../../../src/kernel/bsd/uipc_socket.c":1161] 15 sendit() ["../../../../src/kernel/bsd/uipc_syscalls.c":874] 16 sendto() ["../../../../src/kernel/bsd/uipc_syscalls.c":713] 17 syscall() ["../../../../src/kernel/arch/alpha/syscall_trap.c":540] 18 _Xsyscall() ["../../../../src/kernel/arch/alpha/locore.s":1173] PROBLEM: (Patch ID: OSF405-400059) ******** The ATM signalling timer values are not correctly initialized when the user switches the interface between UNI versions. For example, following the command: atmsig version driver=lta0 uni=3.1 the command: atmsig timers driver=lta0 will show that the timers are still set to the UNI version 3.0 values. PROBLEM: (Patch ID: OSF405-400059) ******** When an outgoing ATM connection is attempted, but is not completed, the lta driver does not free some memory used to keep track of the connection. This can result in excessive consumption of kernel memory. The command: vmstat -M would show a continuing increase in memory allocated to the ATM subsystem. PROBLEM: (QAR 48793) (Patch ID: OSF405-400078) ******** The ATM LANE (LAN Emulation) component was not correctly handling LAN Multicasting. Without basic LAN Multicasting, routing protocols fail to run over LANE interfaces. This forces the use of static routes. The UNIX ioctl, SIOCADDMULTI, will fail when attempting to join a Multicast group. All multicast packets sent to a DIGITAL UNIX LANE interface will get dropped. PROBLEM: (QAR 48537) (Patch ID: OSF405-400084) ******** When a sustained high volume of ATM signalling traffic is present, the system may panic with an "invalid memory write access from kernel mode" error.

The memory problem is most likely to occur when UNI version 3.1 is enabled. PROBLEM: (Patch ID: OSF405-400084) ******** The ATM signaling module generates an illegal SETUP message when a call is placed requesting a Broadband Bearer Class of other than "BCOB-X". This problem does not occur when using Classical IP or LAN Emulation. It could occur for a user-written convergence module which uses a different Bearer Class. PROBLEM: (HPAQA2CEE) (Patch ID: OSF405-400102) ******** The system fails to establish one of the required VCs when joining an ATM Emulated LAN. The problem has been observed particularly when the LAN Emulation server is provided by a FORE Systems switch. The "atmelan show" command will show a control state of something other than S_OPERATIONAL. A signalling trace (via "atmsig trace driver=lta0 state=on read") will show a CONNECT message repeatedly rejected with a Cause Value of "Information Element non-existent or not implemented". PROBLEM: (CLD ZUO101032) (Patch ID: OSF405-400138) ******** This patch fixes a possible kernel memory fault panic that might occur on an ATM ARP server. The panic might also occur if a remote system tries to establish any ATM connection with invalid signalling parameters. The panic occurs in the routine otto_manage_delvc(). PROBLEM: (Patch ID: OSF405-400138) ******** This patch fixes a possible interoperability problem with IBM 8260 switches (certain firmware revisions). The problem prevents the DIGITAL UNIX system from joining an emulated LAN. The system repeatedly rejects of the incoming point-to-multipoint VC connections with a cause value of 100. This problem could also occur any time a remote system attempted a connection where the Forward and Backward SDU sizes were not equal. PROBLEM: (DEKBC1129) (Patch ID: OSF405-400219) ******** This problem is caused by corruption in an internal queue of the LANE ARP code. The symptoms are either a system hang in process_event_queue() or one of the following kernel memory fault stack traces: 0 boot() 1 panic("kernel memory fault") 2 trap() 3 _XentMM() 4 event_queue_insert() 5 la_arp_update() 6 timer_process() PROBLEM: (TKTB26124) (Patch ID: OSF405-400219) ******** This problem is cause by incorrectly keeping track of the reference counts of the internal ATM ESI structures. The following is the stack trace of the kernel panic: 0 boot() 1 panic("ATM ESI CLONE DELETE BOTCH") 2 atm_cmm_esi_cleanup() 3 atm_cmm_collector() PROBLEM: (TKTB26122) (Patch ID: OSF405-400219) ******** The symptoms of this problem vary depending on whether or not patch 138.00 is installed. The problem is triggered by shutting down signaling (i.e., issuing the following command "atmsig down driver=xxxx") and then bringing signaling back up (i.e., "atmsig up driver=xxxx") when LANE is active. Without patch id 138.00 installed the following kernel memory fault will result: 0 boot 1 panic(s = 0xfffffc00006c7680 = "kernel memory fault") 2 trap() 3 _XentMM() 4 otto_manage_delvc() 5 otto_manage() 6 atm_cmm_zombiefy_vc() 7 atm_cmm_new_call() 8 AmUiAmtConInd() 9 amUsrM05S00() 10 amActvConTbl() 11 AmLiAsdDatInd() 12 AsUiAsdDatInd() 13 asV3xAa4Sx_y() 14 asV30ProcessSdPdu() 15 asV30Pdu8S4() 16 AsLiAalDatInd() 17 atm_sig_process_receive() 18 atm_sig_event_process() With patch 138.00 installed, LANE will not restart unless the following commands are issued: "atmconfig down driver=xxxxx" "atmconfig up driver=xxxxx" PROBLEM: (TKTB25174) (Patch ID: OSF405-400219) ******** A system panic is caused by trying to funnel a thread which is in interrupt context.
