Package: util-vserver
Version: 0.30.204-5
Am trying to get a cserver set up running on a sparc64 machine. The
kernel patch works fine and the kernel runs as normal. I seem to be
able to change security context:
devnull:~# chcontext --xid 1122 bash
New security context is 1122
devnull:~# ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.3 0.0 1632 704 ? S 02:28 0:13 init [2]
root 8900 0.9 0.0 3120 1776 ttyS0 S 03:26 0:00 bash
root 8903 0.0 0.0 2952 1136 ttyS0 R+ 03:26 0:00 ps aux
devnull:~#
and I seem to be able to chbind however vserver seems to throw bus
errors.
When executing:
newvserver --hostname XXX --domain YYY --ip ZZZ
all works fine except starting the server

and trying to start the server manually gives:

Stracing this subprocess gives the same output - thus I conclude that
the problem is with chbind:
[00010a90] open("/proc/net/dev", O_RDONLY) = 3
[00010a90] read(3, "Inter-| Receive "..., 8192) = 1553
[00010a90] read(3, "", 6639) = 0
[00010a90] close(3) = 0
[00010a90] mmap(NULL, 8192, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x70000000
[00010a90] open("/proc/net/dev", O_RDONLY) = 3
[00010a90] read(3, "Inter-| Receive "..., 8192) = 1553
[00010a90] read(3, "", 6639) = 0
[00010a90] close(3) = 0
[00011130] --- SIGBUS (Bus error) @ 0 (0) ---
[????????] +++ killed by SIGBUS +++
I appreciate this is something of an obscure bug but I'd be most
greatful for any help fixing it.
Cheers,
