From 3aef1d693f3cc431563a7e6a6aba6a34e5290f03 Mon Sep 17 00:00:00 2001 From: Maxim Dounin Date: Mon, 30 May 2022 21:25:33 +0300 Subject: Reworked multi headers to use linked lists. Multi headers are now using linked lists instead of arrays. Notably, the following fields were changed: r->headers_in.cookies (renamed to r->headers_in.cookie), r->headers_in.x_forwarded_for, r->headers_out.cache_control, r->headers_out.link, u->headers_in.cache_control u->headers_in.cookies (renamed to u->headers_in.set_cookie). The r->headers_in.cookies and u->headers_in.cookies fields were renamed to r->headers_in.cookie and u->headers_in.set_cookie to match header names. The ngx_http_parse_multi_header_lines() and ngx_http_parse_set_cookie_lines() functions were changed accordingly. With this change, multi headers are now essentially equivalent to normal headers, and following changes will further make them equivalent. --- src/http/modules/ngx_http_realip_module.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'src/http/modules/ngx_http_realip_module.c') diff --git a/src/http/modules/ngx_http_realip_module.c b/src/http/modules/ngx_http_realip_module.c index 9586ebe07..f6731e780 100644 --- a/src/http/modules/ngx_http_realip_module.c +++ b/src/http/modules/ngx_http_realip_module.c @@ -134,9 +134,8 @@ ngx_http_realip_handler(ngx_http_request_t *r) ngx_str_t *value; ngx_uint_t i, hash; ngx_addr_t addr; - ngx_array_t *xfwd; ngx_list_part_t *part; - ngx_table_elt_t *header; + ngx_table_elt_t *header, *xfwd; ngx_connection_t *c; ngx_http_realip_ctx_t *ctx; ngx_http_realip_loc_conf_t *rlcf; @@ -168,9 +167,9 @@ ngx_http_realip_handler(ngx_http_request_t *r) case NGX_HTTP_REALIP_XFWD: - xfwd = &r->headers_in.x_forwarded_for; + xfwd = r->headers_in.x_forwarded_for; - if (xfwd->elts == NULL) { + if (xfwd == NULL) { return NGX_DECLINED; } -- cgit
