Hi guys
when i use find to search someting trigger coredump
find command use gunlib source code so i report this
reproduction method:
1??xfs filesystem
2??create 10 directory in /opt
mkdir {1..10}
3??use mkdir.sh to create large number of subdiretcories under the
directory
mkdir.sh
#!/bin/bash
while true
do
for i in {1..10}
do
for j in {1..8000}
do
mkdir /opt/$i/$j
done
done
for i in {1..10}
do
rm -rf /opt/$i/*
done
done
4?? bash mkdir.sh &
5??find /opt -name mess
The same thing happened when use du command because du use
gnulib source code
i use a patch solve the problem:
diff --git a/gl/lib/fts.c b/gl/lib/fts.c
