Linux-2.4.15-pre5 - probably something wrong with /proc/cpuinfo.

[hari]

Hello,

The following shell script (extracted from SuSE 7.1 /etc/rc.d/boot) would 
execute fine on Linux-2.4.14, Linux-2.4.15-pre3 etc.. but not on 
Linux-2.4.15-pre5 (AMD Athlon Computer). Couldn't check it on 
Linux-2.4.15-pre4 as it would not compile successfully.

#!/bin/bash
# set and adjust the CMOS clock
if test "$HWCLOCK_ACCESS" != "no" ; then
echo -n Setting up the CMOS clock
CLOCKCMD=hwclock
while read line; do
        case "$line" in
                *MTX\ Plus*) CLOCKCMD="hwclock --mtxplus --directisa" ;;
                *PReP\ Dual\ MTX*) CLOCKCMD="hwclock --mtxplus --directisa" ;;
        esac
done < /proc/cpuinfo
fi

May someone be kind enough to let me know where the problem could be?

I can't reproduce it here.  Which version of bash it is?

Hello,

It is: GNU bash, version 2.04.0(1)-release

On a related note redirecting the contents of /proc/cpuinfo using 'cat' 
command to a file on my home directory and providing that as an input fixes 
the problem. For eg:

#/bin/bash
# set and adjust the CMOS clock
if test "$HWCLOCK_ACCESS" != "no" ; then
echo -n Setting up the CMOS clock
CLOCKCMD=hwclock
cat /proc/cpuinfo > /root/2.4.15-pre5
while read line; do
        case "$line" in
                *MTX\ Plus*) CLOCKCMD="hwclock --mtxplus --directisa" ;;
                *PReP\ Dual\ MTX*) CLOCKCMD="hwclock --mtxplus --directisa" ;;
        esac
done < /root/2.4.15-pre5
fi

Thanks.

Eww...  If anything, that's cat </proc/cpuinfo | while ...,
but that's quite ugly.  Try the patch I've posted on l-k
(Subject: [PATCH][CFT] seq_file and lseek).

Hello,

Thanks a lot. I have seen your patch included in Linux-2.4.15-pre6, and it 
does fix the issue.

Same problem here... I just removed this part of the boot script - it works 
for me now. But anyway, this is a kernel issue: a stable kernel shouldn´t 
break userspace apps.
