From 8acd40c4951ca822e2fb4672de9e4f23c6b6a97a Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Mon, 4 Jun 2012 11:58:12 +0000 Subject: Merge of r4614, r4624-r4629, r4631: proxy recursive changes. *) Added IPv6 and UNIX-domain socket support in "debug_connection" directive. *) New function ngx_http_get_forwarded_addr() to look up real client address. On input it takes an original address, string in the X-Forwarded-For format and its length, list of trusted proxies, and a flag indicating to perform the recursive search. On output it returns NGX_OK and the "deepest" valid address in a chain, or NGX_DECLINED. It supports AF_INET and AF_INET6. Additionally, original address and/or proxy may be specified as AF_UNIX. *) Realip: chains of trusted proxies and IPv6 support. The module now supports recursive search of client address through the chain of trusted proxies, controlled by the "real_ip_recursive" directive (closes #2). It also gets full IPv6 support (closes #44) and canonical value of the $client_addr variable on address change. Example: real_ip_header X-Forwarded-For; set_real_ip_from 127.0.0.0/8; set_real_ip_from ::1; set_real_ip_from unix:; real_ip_recursive on; *) Geo: chains of trusted proxies and partial IPv6 support. The module now supports recursive search of client address through the chain of trusted proxies, controlled by the "proxy_recursive" directive in the "geo" block. It also gets partial IPv6 support: now proxies may be specified with IPv6 addresses. Example: geo $test { ... proxy 127.0.0.1; proxy ::1; proxy_recursive; } There's also a slight change in behavior. When original client address (as specified by the "geo" directive) is one of the trusted proxies, and the value of the X-Forwarded-For request header cannot not be parsed as a valid address, an original client address will be used for lookup. Previously, 255.255.255.255 was used in this case. *) Geoip: trusted proxies support and partial IPv6 support. The module now supports recursive search of client address through the chain of trusted proxies (closes #100), in the same scope as the geo module. Proxies are listed by the "geoip_proxy" directive, recursive search is enabled by the "geoip_proxy_recursive" directive. IPv6 is partially supported: proxies may be specified with IPv6 addresses. Example: geoip_country .../GeoIP.dat; geoip_proxy 127.0.0.1; geoip_proxy ::1; geoip_proxy 10.0.0.0/8; geoip_proxy_recursive on; --- src/http/ngx_http_core_module.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/http/ngx_http_core_module.h') diff --git a/src/http/ngx_http_core_module.h b/src/http/ngx_http_core_module.h index bfa0b419e..e95d1e069 100644 --- a/src/http/ngx_http_core_module.h +++ b/src/http/ngx_http_core_module.h @@ -513,6 +513,9 @@ ngx_int_t ngx_http_write_filter(ngx_http_request_t *r, ngx_chain_t *chain); ngx_int_t ngx_http_set_disable_symlinks(ngx_http_request_t *r, ngx_http_core_loc_conf_t *clcf, ngx_str_t *path, ngx_open_file_info_t *of); +ngx_int_t ngx_http_get_forwarded_addr(ngx_http_request_t *r, ngx_addr_t *addr, + u_char *xff, size_t xfflen, ngx_array_t *proxies, int recursive); + extern ngx_module_t ngx_http_core_module; -- cgit
