+Subject: tests: Add compatibility with uutils
+
+In some places run_tsets.sh needs to get the size of files, which it does
+with stat(1).  However the syntax to do this is different between GNU
+coreutils stat(1) and BSD's stat(1).  We have some logic that looks for
+"GNU" in the version string to figure out the correct version.
+
+This will break upcoming Ubuntu versions which are now using uutils, a Rust
+reimplementation of coreutils.  These support the same GNU syntax, but
+don't have the "GNU" in the version string.
+
+Update the detection to simply try the GNU version and otherwise assume
+BSD.

+Subject: tests: When building .so from -O asm output mark as non-executable
+ stack
+
+For certain tests, we take the output from dtc -O asm and build it into
+a .so shared library which we then dlopen() for further tests.  Because we
+don't mark it otherwise, it's treated as requiring an executable stack,
+which dlopen() refuses to open as of glibc-2.41.
+
+Of course, the library is pure data, no code, so it certainly doesn't need
+an executable stack.  Add the -znoexecstack linker option to avoid the
+error.

+Subject: pylibfdt/libfdt.i: fix backwards compatibility of return values
+
+When our Python functions wrap `fdt_getprop()` they return a list
+containing `[*data, length]`.
+
+In SWIG v4.2 and earlier SWIG would discard `*data` if it is NULL/None.
+Causing the return value to just be `length`.
+
+But starting in SWIG v4.3 it no longer discards `*data`. So the return
+value is now `[None, length]`.
+
+Handle this compatibility issue in libfdt.i by checking if the return
+value looks like the older 4.2 return value, and casting it to the newer
+style.
+
+See https://github.com/swig/swig/pull/2907
