+From 494ae0c35c883632faf1d22b54083d3e97a7c129 Mon Sep 17 00:00:00 2001
+From: Aurelien DARRAGON <adarragon@haproxy.com>
+Date: Wed, 25 Jan 2023 16:35:00 +0100
+Subject: [PATCH] DEV: hpack: fix `trash` build regression
+
+Since 7d84439 ("BUILD: hpack: include global.h for the trash that is needed
+in debug mode"), hpack decode tool fails to compile on targets that enable
+USE_THREAD. (ie: linux-glibc target as reported by Christian Ruppert)
+
+When building hpack devtool, we are including src/hpack-dec.c as a dependency.
+src/hpack-dec.c relies on the global trash whe debug mode is enabled.
+But as we're building hpack tool with a limited scope of haproxy
+sources, global trash (which is declared in src/chunk.c) is not available.
+Thus, src/hpack-dec.c relies on a local 'trash' variable declared within
+dev/hpack/decode.c
+
+This used to work fine until 7d84439.
+But now that global.h is explicitely included in src/hpack-dec.c,
+trash variable definition from decode.c conflicts with the one from global.h:
+
+  In file included from include/../src/hpack-dec.c:35,
+                   from dev/hpack/decode.c:87:
+  include/haproxy/global.h:52:35: error: thread-local declaration of 'trash' follows non-thread-local declaration
+     52 | extern THREAD_LOCAL struct buffer trash;
+
+Adding THREAD_LOCAL attribute to 'decode.c' local trash variable definition
+makes the compiler happy again.
+
+This should fix GH issue #2009
