[Crash-utility] backtrace - how do I get local and formal parametes - kernel is compiled -O0.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Got by 1st panic crash, crash seems to be working but I don't feel comfortable as with gdb. I can't see the parameters on the stack as variables as with kgdb nor can I see the local variables on the stack. Seems I should be able to get crash working with gdb so I can see the details that gdb can see. I compiled the kernel -O0 and without the framepointer as it seem crash prefers (rather odd). But want to see the locals and formals on the stack and walk up and down the stack and have the context know to crash just as with gdb. I'll re-read your crash paper. Any suggestions? - -piet - ------------------------------------------------- crash> bt -l PID: 1478 TASK: c7ed4570 CPU: 0 COMMAND: "savproxy" ~ #0 [d76bbbb4] crash_kexec at c01ecb41 ~ include/asm/system.h: 259 ~ #1 [d76bbc24] panic at c018bc33 ~ /nethome/piet/src/India-2.6.16.57/linux/kernel/panic.c: 89 ~ #2 [d76bbc44] skb_tcp_zero_copy_iovec at c06d67a0 ~ /nethome/piet/src/India-2.6.16.57/linux/net/core/skbuff.c: 517 ~ #3 [d76bbcb4] tcp_zerocopy_recvmsg at c07e6c14 ~ /nethome/piet/src/India-2.6.16.57/linux/net/ipv4/tcp.c: 1792 ~ #4 [d76bbd8c] receive_tcp_zero_copy_buffers at c06beb89 ~ /nethome/piet/src/India-2.6.16.57/linux/net/socket.c: 3573 ~ #5 [d76bbf2c] sys_zcopy_sockop at c06bc077 ~ /nethome/piet/src/India-2.6.16.57/linux/net/socket.c: 2536 ~ #6 [d76bbfb8] sysenter_entry at c0981544 ~ include/asm/system.h: 279 ~ EAX: 000000bd EBX: 00000005 ECX: 00000006 EDX: 08228cd8 ~ DS: 007b ESI: 00000100 ES: 007b EDI: 00000001 ~ SS: 007b ESP: b59767d0 EBP: b5976828 ~ CS: 0073 EIP: ffffe410 ERR: 000000bd EFLAGS: 00000246 crash> bt PID: 1478 TASK: c7ed4570 CPU: 0 COMMAND: "savproxy" ~ #0 [d76bbbb4] crash_kexec at c01ecb41 ~ #1 [d76bbc24] panic at c018bc33 ~ #2 [d76bbc44] skb_tcp_zero_copy_iovec at c06d67a0 ~ #3 [d76bbcb4] tcp_zerocopy_recvmsg at c07e6c14 ~ #4 [d76bbd8c] receive_tcp_zero_copy_buffers at c06beb89 ~ #5 [d76bbf2c] sys_zcopy_sockop at c06bc077 ~ #6 [d76bbfb8] sysenter_entry at c0981544 ~ EAX: 000000bd EBX: 00000005 ECX: 00000006 EDX: 08228cd8 ~ DS: 007b ESI: 00000100 ES: 007b EDI: 00000001 ~ SS: 007b ESP: b59767d0 EBP: b5976828 ~ CS: 0073 EIP: ffffe410 ERR: 000000bd EFLAGS: 00000246 crash>
