From 72b9a317d2983b3127b8cce21236af8409ff732a Mon Sep 17 00:00:00 2001 From: Ruslan Ermilov Date: Sat, 21 Nov 2015 10:44:07 +0300 Subject: Upstream: fixed "no port" detection in evaluated upstreams. If an upstream with variables evaluated to address without a port, then instead of a "no port in upstream" error an attempt was made to connect() which failed with EADDRNOTAVAIL. --- src/http/modules/ngx_http_fastcgi_module.c | 5 +++-- src/http/modules/ngx_http_proxy_module.c | 5 +++-- src/http/modules/ngx_http_scgi_module.c | 5 +++-- src/http/modules/ngx_http_uwsgi_module.c | 5 +++-- src/http/ngx_http_upstream.c | 12 ++++++++++-- 5 files changed, 22 insertions(+), 10 deletions(-) diff --git a/src/http/modules/ngx_http_fastcgi_module.c b/src/http/modules/ngx_http_fastcgi_module.c index 668719fe..dbd7767f 100644 --- a/src/http/modules/ngx_http_fastcgi_module.c +++ b/src/http/modules/ngx_http_fastcgi_module.c @@ -773,10 +773,11 @@ ngx_http_fastcgi_eval(ngx_http_request_t *r, ngx_http_fastcgi_loc_conf_t *flcf) } else { u->resolved->host = url.host; - u->resolved->port = url.port; - u->resolved->no_port = url.no_port; } + u->resolved->port = url.port; + u->resolved->no_port = url.no_port; + return NGX_OK; } diff --git a/src/http/modules/ngx_http_proxy_module.c b/src/http/modules/ngx_http_proxy_module.c index 19335091..e9224e24 100644 --- a/src/http/modules/ngx_http_proxy_module.c +++ b/src/http/modules/ngx_http_proxy_module.c @@ -1015,10 +1015,11 @@ ngx_http_proxy_eval(ngx_http_request_t *r, ngx_http_proxy_ctx_t *ctx, } else { u->resolved->host = url.host; - u->resolved->port = (in_port_t) (url.no_port ? port : url.port); - u->resolved->no_port = url.no_port; } + u->resolved->port = (in_port_t) (url.no_port ? port : url.port); + u->resolved->no_port = url.no_port; + return NGX_OK; } diff --git a/src/http/modules/ngx_http_scgi_module.c b/src/http/modules/ngx_http_scgi_module.c index 6e5b0770..76c77863 100644 --- a/src/http/modules/ngx_http_scgi_module.c +++ b/src/http/modules/ngx_http_scgi_module.c @@ -569,10 +569,11 @@ ngx_http_scgi_eval(ngx_http_request_t *r, ngx_http_scgi_loc_conf_t * scf) } else { u->resolved->host = url.host; - u->resolved->port = url.port; - u->resolved->no_port = url.no_port; } + u->resolved->port = url.port; + u->resolved->no_port = url.no_port; + return NGX_OK; } diff --git a/src/http/modules/ngx_http_uwsgi_module.c b/src/http/modules/ngx_http_uwsgi_module.c index a50c5532..0313dfa5 100644 --- a/src/http/modules/ngx_http_uwsgi_module.c +++ b/src/http/modules/ngx_http_uwsgi_module.c @@ -771,10 +771,11 @@ ngx_http_uwsgi_eval(ngx_http_request_t *r, ngx_http_uwsgi_loc_conf_t * uwcf) } else { u->resolved->host = url.host; - u->resolved->port = url.port; - u->resolved->no_port = url.no_port; } + u->resolved->port = url.port; + u->resolved->no_port = url.no_port; + return NGX_OK; } diff --git a/src/http/ngx_http_upstream.c b/src/http/ngx_http_upstream.c index 74fffd5c..8a9fbac4 100644 --- a/src/http/ngx_http_upstream.c +++ b/src/http/ngx_http_upstream.c @@ -633,8 +633,18 @@ ngx_http_upstream_init_request(ngx_http_request_t *r) u->ssl_name = u->resolved->host; #endif + host = &u->resolved->host; + if (u->resolved->sockaddr) { + if (u->resolved->port == 0) { + ngx_log_error(NGX_LOG_ERR, r->connection->log, 0, + "no port in upstream \"%V\"", host); + ngx_http_upstream_finalize_request(r, u, + NGX_HTTP_INTERNAL_SERVER_ERROR); + return; + } + if (ngx_http_upstream_create_round_robin_peer(r, u->resolved) != NGX_OK) { @@ -648,8 +658,6 @@ ngx_http_upstream_init_request(ngx_http_request_t *r) return; } - host = &u->resolved->host; - umcf = ngx_http_get_module_main_conf(r, ngx_http_upstream_module); uscfp = umcf->upstreams.elts; -- cgit v1.2.3
