[Buildroot] Strange error when set root password in buildroot

[Woody Wu]

Hi, 

Today I just set the root password in buildroot. Then I got strange
error when building:

/usr/bin/sed -i -e 's,^root:[^:]*:,root:usage: mkpasswd [args] [user]   where arguments are:     -l #      (length of password, default = 9)     -d #      (min # of digits, default = 2)     -c #      (min # of lowercase chars, default = 2)     -C #      (min # of uppercase chars, default = 2)     -s #      (min # of special chars, default = 1)     -v        (verbose, show passwd interaction)     -p prog   (program to set password, default = passwd):,' /home/woody/src/buildroot-2013.05/output/target/etc/shadow
/usr/bin/sed: -e expression #1, char 109: unknown option to `s'
make: *** [target-root-passwd] Error 1

What's the problem? Thanks.

It seems that the mkpasswd on your system is not the same type as
buildroot expects.
Buildroot runs mkpasswd with '-m <method>', which does not seem to be
present on your mkpasswd.

What Linux system is this?
What is the output of:
which mkpasswd
and
mkpasswd -V

(I think the latter will not work in your case anyway, in my case it's:

$ mkpasswd -V
mkpasswd 5.0.19

Maybe you don't understand what I mean.  The build error are build-root
build error, which happened on my host, not on the target.

Yes, I perfectly understand.
During the buildroot build, mkpasswd from the host is called to
generate a hashed version of the root password. For this, 'mkpasswd -m
<method>' is called, but it seems that mkpasswd on your host does not
accept the '-m' option.

sorry, now I understand what you mean.  My linux is slackware linux, the
mkpasswd located in /usr/bin/mkpasswd, which even don't support -V or
--version to check its version number. And, yes, you are right, my
'mkpasswd' does not recognize '-m' option.

Thank you very much!  And, is there a work around?

I'm not sure. Either we have to change buildroot to detect whether -m
is available before using it (if not, it will probably default to
md5). Or we need to find another solution.

Just a wild guess, can you check if there are other mkpasswd's available?
ls -l /bin/mkpasswd /usr/bin/mkpasswd /sbin/mkpasswd /usr/sbin/mkpasswd

A workaround for you is to change buildroot to remove the -m thing,
but it's better if we fix it completely, I think.

Thanks,
Thomas

There is no other mkpasswd on my slackware box. The only one comes from
the expect package. Would you please where to change the '-m' in
buildroot and how?  Thanks.

In system/system.mk, if you change line

TARGET_GENERIC_ROOT_PASSWD_HASH = $(shell mkpasswd -m
"$(TARGET_GENERIC_PASSWD_METHOD)" "$(TARGET_GENERIC_ROOT_PASSWD)")

in

TARGET_GENERIC_ROOT_PASSWD_HASH = $(shell mkpasswd
"$(TARGET_GENERIC_ROOT_PASSWD)")

I guess it will work for you. But this is not an acceptable final solution.

Input from others would be great here.

Best regards,
Thomas

I guess the only option would be to build our own mkpasswd and use it
when the user enters a non-empty root password in the configuration.

Best regards,
