PROBLEM: (ZUO101032) (Patch ID: OSF410-400138) ******** This patch fixes a panic with the message "ltaintr: no TX pkt". An example stack trace is shown below: 0 boot() 1 panic(s = 0xfffffc000065e1f0 = "ltaintr: no TX pkt") 2 ltaintr() 3 kn15aa_dispatch_iointr() 4 _XentInt() 5 swap_ipl() 6 boot() 7 panic(s = 0xfffffc000065e1f0 = "ltaintr: no TX pkt") 8 ltaintr() 9 kn15aa_dispatch_iointr() 10 _XentInt() 11 gh_zero_memory() 12 idle_thread() The panic is a result of the ATM ILMI component overflowing a message buffer. It will only occur for certain patterns of ATM addresses, and is most likely to happen when ATM Classical IP is in use. This patch may also fix other ILMI interoperability problems that do not result in panics. PROBLEM: (ZUO101032) (Patch ID: OSF410-400138) ******** When the default UNI Version 3.0 signalling is used, it can sometimes take a very long time (1.5 minutes or more) for ATM connections to be re-established after a network interruption (e.g. a disconnected cable). This patch changes the default recovery timer and greatly speeds up re-connection following an interruption. PROBLEM: (QAR 49699) (Patch ID: OSF410-400138) ******** 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: OSF410-400138) ******** 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: OSF410-400219) ******** 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() 0 boot() 1 panic("kernel memory fault") 2 trap() 3 _XentMM() 4 process_event_queue() 5 la_arp_refresh_callback() 6 timer_process() PROBLEM: (TKTB26124) (Patch ID: OSF410-400219) ******** This problem is cause by incorrectly keeping track of the refernce 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: OSF410-400219) ******** 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: OSF410-400219) ******** A system panic is caused by trying to funnel a thread which is in interrupt context. The kernel stack trace associated with this problem is as follows: 0 boot() 1 panic("thread_block: interrupt level call") 2 thread_block() 3 unix_release_force() 4 unix_release() 5 cm_rcv() 6 atm_cmm_receive() 7 ottoread() 8 ltaintr() 9 intr_dispatch_post() 10 _XentInt() PROBLEM: (CA7Q10817) (Patch ID: OSF410-400288) ******** When tcpdump is run with ATM LAN emulation, a kernel memory fault occurs. The kernel memory fault is a result of LAN emulation code not setting up support for the packet filter component. A sample stack trace is shown as follows: 0 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2466,] 1 panic(s = 0xfffffc00005974c0 = "thread_block: interrupt level call") ["../../../../src/kernel/bsd/subr_prf.c":707,] 2 thread_block() ["../../../../src/kernel/kern/sched_prim.c":1925,] 3 thread_preempt() ["../../../../src/kernel/kern/sched_prim.c":3820,] 4 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2410,] 5 panic(s = 0xfffffc00005d2bc0 = "kernel memory fault") ["../../../../src/kernel/bsd/subr_prf.c":791] 6 trap() ["../../../../src/kernel/arch/alpha/trap.c":1512,] 7 _XentMM() ["../../../../src/kernel/arch/alpha/locore.s":1424,] 8 pfilt_filter() ["../../../../src/kernel/net/pfilt.c":2757,] 9 ether_input() ["../../../../src/kernel/net/if_ethersubr.c":1123,] 10 lec_rcv_cb() ["../../../../src/kernel/net/if_lane/lec_upper.c":229,] 11 ld_rcv_callback() ["../../../../src/kernel/net/if_lane/lec_data.c":490,] 12 cm_rcv() ["../../../../src/kernel/net/if_lane/cm_sap_shim.c":775,] 13 atm_cmm_receive() ["../../../../src/kernel/atm/cmm/cmm_adi.c":881,] 14 ottoread(0) ["../../../../src/kernel/io/atm/drivers/otto/if_otto.c":2132,] PROBLEM: (QAR 58172) (Patch ID: OSF410-400464) ******** This patch fixes a problem with the ATMworks 351 (Meteor) loadable driver. The driver may not get configured at boot time. The console message seen is "Couldn't register with CMM" just after the display of the devices 8 MAC addresses. PROBLEM: (QAR 55669,55335) (Patch ID: OSF410-405158) ******** This patch fixes an ATM problem. When the ATM subsystem receives a CONNECT message with no signalling information elements (IEs), it corrupts a single byte of kernel memory. PROBLEM: (CLD TKTBB3625) (Patch ID: OSF410-405163) ******** This patch fixes a problem when ATM ELAN's are configured and an ATM switch reboots. This can cause a temporary connectivity problem. Hosts on Ethernet segments may not be able communicate with the Digital UNIX ATM ELAN hosts until the expiration of router ARP timers. The command "atmelan show unitx" displays the Local LEC ATM Address and the Registered MAC Address for the ELAN unit specified. If this command is entered prior to an ATM switch reboot and after an ATM switch reboot, a change in the registered MAC address for the ELAN interface will indicate that any router ARP caches need to be updated for connectivity. PROBLEM: (CLD ZPOBC0559) (Patch ID: OSF410-405164) ******** This patch fixes a problem that occurs on a system running ATM. The system panics with a "kernel memory fault" due to a simple lock time violation. Prior to the crash, the pvc flag is observed as stale on a permanent virtual circuit. The crash occurs after the pvc is deleted with the following command: # atmconfig -pvc ..... A sample stack trace is shown in the following example: 0 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2625] 1 panic(s = 0xfffffc0000658618 = "event_timeout: panic request") ["../../../../src/kernel/bsd/subr_prf.c":707, 0xfffffc000028034c] 2 event_timeout() ["../../../../src/kernel/arch/alpha/cpu.c":1016] 3 simple_lock_miss() ["../../../../src/kernel/arch/alpha/lockprim.s":1255] 4 atm_arp_timer() ["../../../../src/kernel/netinet/atm/atm_arp.c":3952] 5 softclock_scan() ["../../../../src/kernel/bsd/kern_clock.c":1316] 6 lwc_schedule() ["../../../../src/kernel/bsd/lwc.c":172] 7 thread_preempt() ["../../../../src/kernel/kern/sched_prim.c":3792] 8 boot() ["../../../../src/kernel/arch/alpha/machdep.c":2572] 9 panic(s = 0xfffffc000065b510 = "kernel memory fault") ["../../../../src/kernel/bsd/subr_prf.c":791] 10 trap() ["../../../../src/kernel/arch/alpha/trap.c":1539] 11 _XentMM() ["../../../../src/kernel/arch/alpha/locore.s":1424] 12 simple_lock_fault() ["../../../../src/kernel/kern/lock.c":2053] 13 simple_lock_time_violation()["../../../../src/kernel/kern/lock.c":2135] 14 atmip_output() ["../../../../src/kernel/netinet/atm/ip_converge.c":428] 15 ip_output() ["../../../../src/kernel/netinet/ip_output.c":637] 16 icmp_send() ["../../../../src/kernel/netinet/ip_icmp.c":744] 17 icmp_reflect() ["../../../../src/kernel/netinet/ip_icmp.c"] 18 icmp_input() ["../../../../src/kernel/netinet/ip_icmp.c":515] 19 ipintr() ["../../../../src/kernel/netinet/ip_input.c":971] 20 netisr_thread() ["../../../../src/kernel/net/netisr.c":863] PROBLEM: (ZPOBA0887/QAR 56809,56952,55546) (Patch ID: OSF410-405183) ******** This patch fixes two kernel memory faults and a system startup crash caused by the ATM convergence subsystem. This patch fixes the following symptoms: 1. atmarp -c lis= driver= PVC command causes kernel memory fault. 2. ATM startup crashes system when it's not attached to the ATM network. 3. kmf simple_lock_fault -atm_arp_timer with the following stack components: panic() _XentMM simple_lock_fault() simple_lock_time_violation() atm_arp_timer() softclock_scan() PROBLEM: (QAR-60134) (Patch ID: OSF410-405220) ******** The Digital UNIX LAN Emulation client doesn't comply with the LANE V1 spec when locating the LAN Emulation Configuration Server (LECS). The client is required to ask the switch via ILMI for the ATM address of the LECS. The switch had to be setup to use the ATM Forums well known address "4700790000000000000000000000A03E00000100" to allow Digital UNIX LANE to locate and connect to the LECS. PROBLEM: (MCGM30SC1) (Patch ID: OSF410-405225) ******** ATM will fail to connect on incoming calls that are UNI version 3.1. In some cases incorrect data for the Elan name was being used. This would cause D/UNIX to try to join an invalid Elan. This fix also allows the "elan_name" option to be set with the "les" option. PROBLEM: (QAR 52619) (Patch ID: OSF410-405234) ******** This patch fixes a problem where the Virtual Circuit may hang and is unable to transmit when running Classical IP under heavy load. Attempting to transmit, ( e.g. "ping"), on that Virtual Circuit was returning ENOBUFS. PROBLEM: (QAR 54387) (Patch ID: OSF410-405234) ******** This patch fixes a problem where the ATM subsystem could corrupt the malloc memory pool. Most likely it would cause a kernel memory fault of some sort. PROBLEM: (QAR 60243, CLD HPAQ2147B) (Patch ID: OSF410-405261) ******** This patch fixes a problem in which an ATM CLIP connection does not send data.
