Subject: [users@httpd] suexec with mod_chroot: "command not in docroot"

Hi,

I've installed mod_chroot for Apache (2.0.53-Ubuntu), but have now problems=
=20
with suexec complaining:

[2005-07-20 06:28:13]: uid: (1003/xxxxx) gid: (1003/1003) cmd:=20
php4-fcgi-starter
[2005-07-20 06:28:13]: command not in docroot=20
(/fcgi-scripts/web2/php4-fcgi-starter)

php4-fcgi-starter is a script that should start php-fcgi (I'm using=20
mod_fastcgi).

My suexec-docroot is "/", because of mod_chroot:
# /usr/lib/apache2/suexec2 -V
 -D AP_DOC_ROOT=3D"/"
 -D AP_GID_MIN=3D100
 -D AP_HTTPD_USER=3D"www-data"
 -D AP_LOG_EXEC=3D"/var/log/apache2/suexec.log"
 -D AP_SAFE_PATH=3D"/usr/local/bin:/usr/bin:/bin"
 -D AP_UID_MIN=3D100
 -D AP_USERDIR_SUFFIX=3D"public_html"

Therefor I have rebuild the Ubuntu package from source (got the error "cann=
ot=20
get docroot information (/var/www)" before).

=46rom suexec.c it is this part that throws the error:
   if ((strncmp(cwd, dwd, strlen(dwd))) !=3D 0) {
        log_err("command not in docroot (%s/%s)\n", cwd, cmd);
        exit(114);
    }

I'm not sure, what cwd and dwd are set to, but it errors here.. :(

btw: this error message should be changed into something more verbose:
 log_err("command (%s/%s) not in docroot (%s)\n", cwd, cmd, dwd);
like some of the others, too.

It is really frustrating and would be much easier in my humble opinion, if=
=20
suexec would have a chroot() functianality.

Do you have any suggestions? Is it a bug in suexec?

Thanks for any ideas and suggestions.
