RE: [Panicsel-developers] error in sensor

[Cress, A. R <and...@in...>]

I found the problem, in ipmimv.c it tries to include stdin on the select.
This is fixed in panicsel 1.3.1, just released.

Subject: [Panicsel-developers] error in sensor




Hi,

I found a strange problem with sensor from panicsel-1.3.0,
linux 2.4.20, openIPMI drivers v18:

It works like a charm from the commandline but fails when called from
crontab. 

## this a output snippet from "strace sensor" when it works:

open("/dev/ipmi0", O_RDWR)              = 3
ioctl(3, 0x80046910, 0xbfffec6c)        = 0
ioctl(3, 0x8014690d, 0xbfffec70)        = 0
select(4, [0 3], NULL, NULL, {5, 0})    = 1 (in [3], left {4, 780000})
ioctl(3, I2OEVTGET, 0xbfffecc0)         = 0

## and this happens when I try to run it from crontab:

open("/dev/ipmi0", O_RDWR)              = 3
ioctl(3, 0x80046910, 0xbffff0e4)        = 0
ioctl(3, 0x8014690d, 0xbffff0f0)        = 0
select(4, [0 3], NULL, NULL, {5, 0})    = 1 (in [0], left {5, 0})
ioctl(3, I2OEVTGET, 0xbffff140)         = -1 EAGAIN (Resource temporarily
unavailable)


I think there is some subtle error in the filedescriptor handling in
ipmicmd_mv(). Something goes wrong when stdin is redirected: 
I can reproduce the error without crontab by simply 
calling "sensor < /dev/null" 



Cheers, Meik
