Wong I was testing a patch to strengthen the buffer length validation of attr log intent items during log recovery, when I noticed that the lengths of the logged values were (mostly) a single byte larger than the alleged attribute value. Upon further investigation, I noticed this code in the test: echo "$attr_value" | attr -s The 'echo' command generally emits a newline before exiting, which means that the 16-byte "attr16" value was actually storing 17 bytes. This affects all the test cases except for the attr64k tests, since the attr(1) command helpfully/silently truncates the value buffer at 65536 bytes. Fix the test to store values of exactly the length we want, and add a couple more test cases to check that everything still works when the value length is not an exact multiple of sizeof(u32).
