From d6095c7d9ed4a182734eb080776d37d7f730f7d9 Mon Sep 17 00:00:00 2001 From: Phil Pennock Date: Sun, 9 Mar 2014 12:44:59 -0400 Subject: Let chdir be overriden with FCGI_CHDIR chdir to directory which holds scripts doesn't work well with some CGIs. Let the FastCGI invoker provide `FCGI_CHDIR` which can be `-` to inhibit chdir, or another place to chdir to. --- fcgiwrap.c | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) diff --git a/fcgiwrap.c b/fcgiwrap.c index d4f7901..458b6d4 100644 --- a/fcgiwrap.c +++ b/fcgiwrap.c @@ -521,6 +521,7 @@ static void handle_fcgi_request(void) int pipe_err[2]; char *filename; char *last_slash; + char *p; pid_t pid; struct fcgi_context fc; @@ -559,15 +560,22 @@ static void handle_fcgi_request(void) if (!is_allowed_program(filename)) cgi_error("403 Forbidden", "The given script is not allowed to execute", filename); - last_slash = strrchr(filename, '/'); - if (!last_slash) - cgi_error("403 Forbidden", "Script name must be a fully qualified path", filename); + p = getenv("FCGI_CHDIR"); + if (p == NULL) { + last_slash = strrchr(filename, '/'); + if (!last_slash) + cgi_error("403 Forbidden", "Script name must be a fully qualified path", filename); - *last_slash = 0; - if (chdir(filename) < 0) - cgi_error("403 Forbidden", "Cannot chdir to script directory", filename); + *last_slash = 0; + if (chdir(filename) < 0) + cgi_error("403 Forbidden", "Cannot chdir to script directory", filename); - *last_slash = '/'; + *last_slash = '/'; + } else if (strcmp(p, "-") != 0) { + if (chdir(p) < 0) { + cgi_error("403 Forbidden", "Cannot chdir to FCGI_CHDIR directory", p); + } + } execl(filename, filename, (void *)NULL); cgi_error("502 Bad Gateway", "Cannot execute script", filename); -- cgit v1.2.3
