+Subject: [PATCH] Inherit LDFLAGS for TLS and RDMA modules (#3344)
+
+With current Makefile, `LDFLAGS` are not used for modules.
+
+This results in security options not applied.
+
+```
+$ annocheck /usr/lib64/valkey/modules/rdma.so
+annocheck: Version 12.99.
+Hardened: rdma.so: FAIL: bind-now test because not linked with -Wl,-z,now
+Hardened: Rerun annocheck with --verbose to see more information on the tests.
+Hardened: rdma.so: Overall: FAIL.
+```
+
+With this patch
+
+```
+$ annocheck /usr/lib64/valkey/modules/rdma.so
+annocheck: Version 12.99.
+Hardened: rdma.so: PASS.
