How do I set suhosin.request.max_* with .htaccess? Only suhosin.post.max_* work

7.1k views Asked by At

I've set suhosin.perdir = 'p' in my ini file. I would now like to change suhosin ini settings on a per-folder basis.

The following all work (running phpinfo() inside the desired folder shows the changed values):

php_value suhosin.post.max_array_depth 100
php_value suhosin.post.max_array_index_length 128
php_value suhosin.post.max_name_length 128
php_value suhosin.post.max_value_length 2000000
php_value suhosin.post.max_totalname_length 512
php_value suhosin.post.max_vars 1000

But when I also add the .request settings (which I understand are an upper limit for the .post settings), they do not change:

php_value suhosin.request.max_array_depth 100
php_value suhosin.request.max_array_index_length 128
php_value suhosin.request.max_name_length 128
php_value suhosin.request.max_value_length  2000000
php_value suhosin.request.max_totalname_length 512
php_value suhosin.request.max_vars 1000

Do you have any idea if there is anything else I have to check/setup? Am I forgetting someting?

Thank you! Matei

Ok, I've finally found the solution. I was going to download the Suhosin code to take a look when I found this post, explaining that the perdir "p" directive only affects to the post variables:

/* no deactivation so check the flags */
while (*tmp) {
    switch (*tmp) {
        case 'l':
        case 'L':
            SUHOSIN_G(log_perdir) = 1;
            break;
        case 'e':
        case 'E':
            SUHOSIN_G(exec_perdir) = 1;
            break;
        case 'g':
        case 'G':
            SUHOSIN_G(get_perdir) = 1;
            break;
        case 'c':
        case 'C':
            SUHOSIN_G(cookie_perdir) = 1;
            break;
        case 'p':
        case 'P':
            SUHOSIN_G(post_perdir) = 1;
            break;
        case 'r':
        case 'R':
            SUHOSIN_G(request_perdir) = 1;
            break;
        case 's':
        case 'S':
            SUHOSIN_G(sql_perdir) = 1;
            break;
        case 'u':
        case 'U':
            SUHOSIN_G(upload_perdir) = 1;
            break;
        case 'm':
        case 'M':
            SUHOSIN_G(misc_perdir) = 1;
            break;
    }
    tmp++;
}

If you want perdir options both per post and request, you need to edit your php.ini

suhosin.perdir=pr

or .htaccess

php_value suhosin.perdir pr

so the value for perdir is pr
