Merge pull request #3812 from ronald-cron-arm/aes-zeroize-less-2.16
Backport 2.16: Remove a useless zeroization

David Brown ff28df98f5 cmake: Avoid using target_properties for old cmake
CMake versions less than 3.0 do not support the `target_sources`
command.  In order to be able to support v2.8.12.2 of cmake, add the
extra targets directly to the target command.

This is a backport from the development branch, except that the uses in
this branch are simpler, and modifying the SOURCES property directly is
not needed.

Fixes #3801

Backport 2.16: Fix printf escape errors in shell scripts
2020-11-04 17:52:08 +01:00
Gilles Peskine ffdcadf084 Fix printf escape errors in shell scripts
Fix `printf "$foo"` which treats the value of `foo` as a printf format
rather than a string.

I used the following command to find potentially problematic lines:
```
git ls-files '*.sh' | xargs egrep 'printf +("?[^"]*|[^ ]*)\$'
```
The remaining ones are false positives for this regexp.

The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive
PASS
```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

Gilles Peskine 663d0993ec ssl-opt.sh --help: don't show regexps for -f and -e
Showing a regexp to say that by default all tests are executed is not
particularly helpful.

If we ever add a default exclusion list or a default filter, we can
edit the documentation again.

Gilles Peskine 91ee76380c Put local variables in a struct
This way we can have a single call to mbedtls_platform_zeroize, which
saves a few bytes of code size.

Additionally, on my PC, I notice a significant speed improvement
(x86_64 build with MBEDTLS_AESNI_C disabled, gcc 5.4.0 -O3). I don't
have an explanation for that (I expected no measurable difference).

Gilles Peskine 02c7b48a70 Remove a useless zeroization
Remove the zeroization of a pointer variable in the AES block
functions. The code was valid but spurious and misleading since it
looked like a mistaken attempt to zeroize the pointed-to buffer.
Reported by Antonio de la Piedra, CEA Leti, France.

Note that we do not zeroize the buffer here because these are the
round keys, and they need to stay until all the blocks are processed.
They will be zeroized in mbedtls_aes_free().

Backport 2.16: Restore retry in rsa_prepare_blinding()
2020-09-30 16:23:04 +01:00
Peter Kolbus b2aeb75509 Restore retry in rsa_prepare_blinding()
Starting with commit 49e94e3, the do/while loop in
`rsa_prepare_blinding()` was changed to a `do...while(0)`, which
prevents retry from being effective and leaves dead code.

Restore the while condition to retry, and lift the calls to finish the
computation out of the while loop by by observing that they are
performed only when `mbedtls_mpi_inv_mod()` returns zero.

Gilles Peskine e39d14b142 Fix "make -C tests/data_files -f ..."
The toplevel directory is actually just ../..: the makefile commands
are executed in the subdirectory. $(PWD) earlier was wrong because it
comes from the shell, not from make. Looking up $(MAKEFILE_LIST) is
wrong because it indicates where the makefile is (make -f), not which
directory to work in (make -C).

Gilles Peskine 319ecf3192 Initialize ret from test code
The test function mbedtls_mpi_lt_mpi_ct did not initialize ret in test
code. If there was a bug in library code whereby the library function
mbedtls_mpi_lt_mpi_ct() did not set ret when it should, we might have
missed it if ret happened to contain the expected value. So initialize
ret to a value that we never expect.

If test_fail is called multiple times in the same test case, report
the location of the first failure, not the last one.

With this change, you no longer need to take care in tests that use
auxiliary functions not to fail in the main function if the auxiliary
function has failed.
