Description Ulrich Drepper 2007-03-16 10:52:47 EDT
Description of problem:
The runcon program reorders parameters since it uses the default getopt_long
setup.  But runcon differs from su here since su does not take a command and its
parameters on the command line.  Trying to run

  runcon -t unconfined_t /usr/sbin/prelink --no-update-cache some/binary

fails since --no-update-cache is no option for runcon.  But runcon shouldn't use
it in the first place.  Of course one can add -- as a parameter before the
program name but this is not how other programs with similar interface work,
they don't require this kind of knowledge from the user (strace, sh, ...).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.echo 'int main(){return 0;}' > u.c
2.gcc -o u u.c
3.runcon -t unconfined_t /usr/sbin/prelink -N ./u
Actual results:
runcon: invalid option -- N

Expected results:

Additional info:
The solution is easy: add + as the first character in the option string of the
getopt_long call.  I very much doubt any script today depends on this level of
option reordering so it should not introduce any regression.

Hi Uli,
Thanks for the report.  I've fixed it on the selinux branch, upstream:
