+Subject: [PATCH] meson.build: Disable stack protection for Buildroot packaging
+
+In Buildroot, the SSP flags are passed via the wrapper, and only flags
+supported by the toolchain will be used. So the SSP flags can be
+safely removed from the build files.
+
+Fixes:
+  src/basic/libbasic.a.p/log.c.o: in function `write_to_console.isra.0':
+  log.c:(.text.write_to_console.isra.0+0x154): undefined reference to `__stack_chk_fail_local'
+
+Upstream: N/A [Buildroot specific]

+Subject: [PATCH basu] memfd-util.c: Use F_ADD_SEALS definition from missing.h
+
+uClibc and glibc (until version 2.27, 2018) implementations don't
+support F_ADD_SEALS and other F_SEAL_xxx flags.
+'missing.h' was removed from 'memfd-util.c' in 37dbb2fcb ("Remove
+useless includes").

+	  basu is the sd-bus library, extracted from systemd.
+
+	  Some projects rely on the sd-bus library for DBus support.
+	  However not all systems have systemd or elogind installed.
+	  This library provides just sd-bus (and the busctl utility).
