These were done by my misunderstanding of the mmap cache behavior.
Also, this updates the comments added by
df04b9ed86.
note that this slightly changes the semantic of assert when NDEBUG is
defined. if there's an extern function call (without attribute pure or
similar) then the compiler has to assume it has side effects and still
emit the function call.
whereas the old assert guaranteed that nothing will be evaluated on
NDEBUG.
Closes: https://github.com/systemd/systemd/issues/29408
This matches the change to tpm2_seal(), which now accepts a Tpm2Context instead
of a device string.
This also allows using the same TPM context for sealing and unsealing, which
will be required by (future) test code when sealing/unsealing using a transient
key.
Simplify the function with GREEDY_REALLOC_APPEND(). Also limit the size_t-sized
max value to UINT32_MAX since that's the maximum of the range this searches,
and the max parameter for tpm2_get_capability() is uint32_t.
The test expects TPM2_CC_FIRST - 1 and TPM2_CC_LAST + 1 to be unsupported, but
those are not necessarily invalid commands. Instead test known-invalid
commands. Also add some more valid commands.
Because most TPM2 functions here are 'library-like' functions, they should be
at debug level, not error level.
The only functions not reduced to logging at debug are tpm2_list_devices(),
since it is expected to print output, and the tpm2_parse_pcr_argument_*()
functions, since the system-wide parse_*_argument() functions generally log at
error level.
Otherwise they might leave stuff behind if they don't respond fast
enough to the first SIGTERM and get SIGKILLEd, which then breaks reusing
the unit name further in the test:
