Hello,

don't know where to properly send this, so I'm hereby sending this to the
address specified in the "REPORTING-BUGS" document.

[1.] One line summary of the problem:

Memory cached files get corrupt

[2.] Full description of the problem/report:

When doing multiple "md5sum" on the same, cached, files, over and over -
the result varies. The same file(s) get different checksums in some
cases.

Doing a memory (RAM) diagnostic shows everything is ok.

Same version of md5sum (md5sum (coreutils) 5.2.1) on other, similar
machines does not show this problem.

[3.] Keywords (i.e., modules, networking, kernel):

kernel, file caching, memory caching

[4.] Kernel version (from /proc/version):

Linux version 2.6.15.6 (root@burk) (gcc version 3.3.6) #4
SMP PREEMPT Thu Mar 16 17:10:13 CET 2006

[5.] Most recent kernel version which did not have the bug:

unknown

[6.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

N/A

[7.] A small shell script or example program which triggers the
problem (if possible)

------
#!/usr/bin/bash
# This script will create 35 20MB-files containing only nulls,
# load all of it into the ram file cache (using md5sum), and then
# keep md5sum:ing the same files a hundred times.
# If everything works fine, all files will have the same checksum.
# If not, sometimes, some files will return a different checksum!
PID=$$
MAXFILES=35
MD5LOOPS=100

echo "[1/4] Removing old cache files..."

rm -f cache.*-*-* 2>/dev/null

echo "[2/4] Creating files to cache..."
while [ 0$MAXFILES -gt 0 ]; do
echo -ne "$MAXFILES left \r"
dd if=/dev/zero of=cache.$RANDOM-$RANDOM-$RANDOM \
bs=1024 count=20000 2>/dev/null
MAXFILES=`expr 0$MAXFILES - 1`
done

echo " "

echo "[3/4] Starting background looping md5sum... ($MD5LOOPS runs)"

while [ 0$MD5LOOPS -gt 0 ]; do
md5sum cache.*-*-* >> md5log.$PID.lis
MD5LOOPS=`expr 0$MD5LOOPS - 1`
done &

CPID=$!

echo "[4/4] Checking for bad checksums..."

while ps -p $CPID >/dev/null 2>&1; do
AMNT=`awk '$1!="91b82dcc83230890dbcdfc6b80571ddd"' md5log.$PID.lis | \
wc -l`
echo MD5 discrepancies so far: $AMNT
sleep 5
done
------

Example output:

[1/4] Removing old cache files...
[2/4] Creating files to cache...
