In my opinion this is a valid behavior, and the test is just weird; it's passing
in *both* an unaddressable payload and an invalid description, so it's not clear
which case it's meant to be testing. (Generally, if a syscall will fail for
more than one reason, it's not guaranteed which error code you'll get.)
In any case, once we have a fix merged, it would be nice for there to be an ltp
test added for the "NULL payload with nonzero length" case with one of the key
types that crashed the kernel.

That is quite common problem with LTP testcases. Do you care to send a
patch or should I fix that?
In any case, once we have a fix merged, it would be nice for there to
be an ltp
test added for the "NULL payload with nonzero length" case with one of the key
types that crashed the kernel.
Here as well, feel free to send a patch or at least point us to a
reproducer that could be turned into a testcase.

I'll plan to send a patch. Also, it looks like the testing that LTP does of
add_key() is very sparse, so I'll try to extend it a bit.

I'll plan to send a patch for that as well.

There's more testing in the testsuite that's with the keyutils package.
