From 302b9f8d7a3805bfd25ecf267a8ddd730c6887b3 Mon Sep 17 00:00:00 2001 From: Maciej Zdeb Date: Fri, 20 Nov 2020 12:12:24 +0000 Subject: [PATCH] BUG/MINOR: http_htx: Fix searching headers by substring Function __http_find_header is used to search headers by name using specified matching method. Matching by substring returned unexpected results due to wrong length of substring supplied to strnistr function. Fixed also the boolean condition by inverting it, as we're interested in headers that contains the substring. This patch should be backported as far as 2.2 --- src/http_htx.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/http_htx.c b/src/http_htx.c index b27b0836c..9570b1ea7 100644 --- a/src/http_htx.c +++ b/src/http_htx.c @@ -201,7 +201,7 @@ static int __http_find_header(const struct htx *htx, const void *pattern, struct goto next_blk; break; case HTTP_FIND_FL_MATCH_SUB: - if (strnistr(n.ptr, n.len, name.ptr, n.len) != NULL) + if (!strnistr(n.ptr, n.len, name.ptr, name.len)) goto next_blk; break; default:
