>Description:
Some command that imprimented by RPC takes kernel panic. For example, When run following command on jail enviroment,
your kernel will panic.
rusers -l localhost
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc017827d
stack pointer = 0x10:0xcfededf8
frame pointer = 0x10:0xcfededfc
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 2054 (rusers)
interrupt mask =
trap number = 12
panic: page fault
In another case, popper which use DRAC(for POP before SMTP) takes same problem. DRAC patch for popper using RPC.
And, I found similer problem on GNATS database at misc/19839.
>How-To-Repeat:
Any time, please run command rusers -l localhost on jail enviroment.
May be any program that using RPC takes same probrem.
