[issue1341] [PATCH]: printenv(1): don't allow '=' in name

Stathis Kamperis <[e-mail]> added the comment:

I am going to push this tomorrow or the day after, unless someone objects.

Just for the record, I have filed a PR in NetBSD bug database as well and t=
hey
fixed it differently:

..=2E.
        if (argc !=3D 1)
                usage();
        if (strchr(*argv, '=3D') !=3D NULL)
                errx(1, "Invalid environment variable %s", *argv);
        len =3D strlen(*argv);
        for (ep =3D environ; *ep; ep++)
..=2E.

POSIX says that env vars shouldn't contain an '=3D' sign and functions as
setenv(3) fail with EINVAL if the supplied name contains an equal sign.


Cheers,
Stathis
