Add missing compilation guards that broke the build if either GCM or
CCM was not defined.
Add missing guards on test cases that require GCM or CBC.
The build and tests now pass for any subset of {MBEDTLS_CCM_C,
MBEDTLS_GCM_C}. There are still unused variables warnings if neither
is defined.
Fix parsing error that contains special character.
The previous implementation replaced the `:` char with `\n`,
and split on `\n`. Test data containing strings with `\n`
were split as well. Fixes#2193.
The split function caused strings containing `\:` to add
another escape char, resulting in `\\:`. This caused the
tests with the `\:` in the string data to fail.
The fix doesn't replace with `\n`, but splits all `:` that
are not preceded with `\`. After that, removes the preceding `\` char.
Refactor `mpi_write_hlp()` to not be recursive, to fix stack overflows.
Iterate over the `mbedtls_mpi` division of the radix requested,
until it is zero. Each iteration, put the residue in the next LSB
of the output buffer. Fixes#2190
Refactor mbedtls_ctr_drbg_update_seed_file and
mbedtls_hmac_drbg_update_seed_file to make the error logic clearer.
The new code does not use fseek, so it works with non-seekable files.
Since the AD too long is a limitation on Mbed TLS,
HW accelerators may support this. Run the test for AD too long,
only if `MBEDTLS_CCM_ALT` is not defined.
Addresses comment in #1996.
Write an all-bits-zero NV seed file for the tests. Without this, if
the seed file is not present when this test suite is executed, the
PSA module initialization will fail, causing most test cases to fail.
Also write an all-bits-zero NV seed file at the end. The test cases in
this test suite mess with the file, but subsequent test suites may
need it.
When testing with custom entropy sources, if MBEDTLS_ENTROPY_NV_SEED
is enabled at compile time but the NV seed source is not used at
runtime, mbedtls_entropy_func makes a second pass anyway. Cope with
this in the test code by telling the entropy module not to make this
second pass.
Add a function to configure entropy sources. For testing only.
Use it to test that the library initialization fails properly if there is no
entropy source.
