+Subject: [PATCH] build_support: handle runtime errors and return None for
+ invalid max_priority
+
+When cross-compiling, test binaries may fail to execute on the host system if
+the target toolchain was built against a newer glibc version than what is
+available on the host.
+
+For example, on Ubuntu 20.04 the following error occurs:
+
+./build_support/src/sniff_mq_prio_max: /lib/x86_64-linux-gnu/libc.so.6: version
+`GLIBC_2.34' not found (required by ./build_support/src/sniff_mq_prio_max)
+
+This change ensures that such runtime errors are gracefully handled, and
+max_priority is set to None when the test binary cannot be executed.
+
+Upstream-Status: Pending
