Subject: command: hashsum: md5sum reports wrong sum for the file named 4k.bin
Date: Wed, 20 Dec 2017 13:48:14 +0300 [thread overview]
Message-ID: <20171220104814.4snxmloobeywnuwb@localhost.localdomain> (raw)
Hi,
The md5sum command reports wrong sum for a file named 4k.bin and, I guess, for
other files named alike. Here are the commands to reproduce the bug:
barebox@barebox sandbox:/ memcpy -s /dev/zero -d _4k.bin 0 0 4k
barebox@barebox sandbox:/ md5sum _4k.bin
620f0b67a91f7f74151bc5be745b7110 _4k.bin
barebox@barebox sandbox:/ cp _4k.bin 4k.bin
barebox@barebox sandbox:/ md5sum 4k.bin
d41d8cd98f00b204e9800998ecf8427e 4k.bin
barebox@barebox sandbox:/ cp 4k.bin __4k.bin
barebox@barebox sandbox:/ md5sum __4k.bin
620f0b67a91f7f74151bc5be745b7110 __4k.bin
barebox@barebox sandbox:/ version
barebox 2017.12.0 #4 Wed Dec 20 12:26:57 MSK 2017
barebox@barebox sandbox:/ Terminated
$ dd if=/dev/zero bs=4k count=1 | md5sum
