By default, keep allowing SHA-1 in key exchange signatures. Disabling
it causes compatibility issues, especially with clients that use
TLS1.2 but don't send the signature_algorithms extension.
SHA-1 is forbidden in certificates by default, since it's vulnerable
to offline collision-based attacks.
There is now one test case to validate that SHA-1 is rejected in
certificates by default, and one test case to validate that SHA-1 is
supported if MBEDTLS_TLS_DEFAULT_ALLOW_SHA1 is #defined.
SHA-1 is now disabled by default in the X.509 layer. Explicitly enable
it in our tests for now. Updating all the test data to SHA-256 should
be done over time.
With SHA-1 deprecation, we need a few certificates using algorithms in
the default support list. Most tests still use SHA-1 though.
The generation process for the new certificates is recorded in the makefile.
The ECJPAKE test suite uses a size zero array for the empty password
used in the tests, which is not valid C. This commit fixes this.
This originally showed up as a compilation failure on Visual Studio
2015, documented in IOTSSL-1242, but can also be observed with GCC
when using the -Wpedantic compilation option.
Fixed a bug in ssl_srv.c when parsing TLS_FALLBACK_SCSV in the
ciphersuite list that caused it to miss it sometimes. Reported by Hugo
Leisink as issue #810. Fix initially by @andreasag01; this commit
isolates the bug fix and adds a non-regression test.
Modify tests/scripts/check-doxy-blocks.pl to ensure that:
* It can only be run from the mbed TLS root directory.
* An error code is returned to the environment when a potential error
in the source code is found.
The test case was generated by modifying our signature code so that it
produces a 7-byte long padding (which also means garbage at the end, so it is
essential in to check that the error that is detected first is indeed the
padding rather than the final length check).
The modular inversion function hangs when provided with the modulus 1. This commit refuses this modulus with a BAD_INPUT error code. It also adds a test for this case.
The TLS client and server code was usually closing the connection in
case of a fatal error without sending an alert. This commit adds
alerts in many cases.
Added one test case to detect that we send the alert, where a server
complains that the client's certificate is from an unknown CA (case
tracked internally as IOTSSL-1330).
Added command line arguments --port and --proxy-port to choose the
ports explicitly instead of deriving them from the PID. This
facilitates debugging e.g. with Wireshark.
Fix a buffer overflow when writting a string representation of an MPI
number to a buffer in hexadecimal. The problem occurs because hex
digits are written in pairs and this is not accounted for in the
calculation of the required buffer size when the number of digits is
odd.
The first three test cases from test_suites_pkparse.data failed because
the key file they read requires DES to be read. However, MBEDTLS_DES_C
was missing from the dependency list.
This curve has special arithmetic on 64 bit platforms and an untested
path lead to trying to free a buffer on the stack.
For the sake of completeness, a test case for a point with non-affine
coordinates has been added as well.
Fixes a regression introduced by an earlier commit that modified
x509_crt_verify_top() to ensure that valid certificates that are after past or
future valid in the chain are processed. However the change introduced a change
in behaviour that caused the verification flags MBEDTLS_X509_BADCERT_EXPIRED and
MBEDTLS_BADCERT_FUTURE to always be set whenever there is a failure in the
verification regardless of the cause.
The fix maintains both behaviours:
* Ensure that valid certificates after future and past are verified
* Ensure that the correct verification flags are set.
Modifies the function mbedtls_x509_crl_parse() to ensure that a CRL in PEM
format with trailing characters after the footer does not result in the
execution of an infinite loop.
Fix potential integer overflows in the following functions:
* mbedtls_md2_update() to be bypassed and cause
* mbedtls_cipher_update()
* mbedtls_ctr_drbg_reseed()
This overflows would mainly be exploitable in 32-bit systems and could
cause buffer bound checks to be bypassed.
Add a test to ssl-opt.sh to ensure that in DTLS a 6 byte record counter
is compared in ssl_check_ctr_renegotiate() instead of a 8 byte one as in
the TLS case. Because currently there are no testing facilities to check
that renegotiation routines are triggered after X number of input/output
messages, the test consists on setting a renegotiation period that
cannot be represented in 6 bytes, but whose least-significant byte is 2.
If the library behaves correctly, the renegotiation routines will be
executed after two exchanged.
Fixes strict C99 builds in all.sh with glibc version >2.19 where platform support
wasn't being compiled in automatically.
Also fixes C99 syntax with armclang.
Changes use of mklink in Windows test builds, to create junctions instead of
directory symbolic links. This removes the need for an elevated command prompt
when running cmake to create the Visual Studio project files.
Tighten up the test options in all.sh, test-ref-configs.pl and curves.pl
to ensure the builds are strict for all warnings, warnings are treated
as errors, and that wherever possible builds are strict to the C99
standard. (Note that builds that use the Unix sockets API cannot be).
Modify the script at tests/scripts/all.sh to export the variable
MAKEFLAGS with -j if it was not set before. This should decrease the
total runtime of tests/scripts/all.sh by letting make run multiple jobs
in parallel. Also, add a check at the top of the script to cause a
failure if the environment is not Linux.

Fix an incorrect condition in ssl_check_ctr_renegotiate() that compared
64 bits of record counter instead of 48 bits as described in RFC 6347
Section 4.3.1. This would cause the function's return value to be
occasionally incorrect and the renegotiation routines to be triggered
at unexpected times.
The tests load certificate chains from files. The CA chains contain a
past or future certificate and an invalid certificate. The test then
checks that the flags set are MBEDTLS_X509_BADCERT_EXPIRED or
MBEDTLS_X509_BADCERT_FUTURE.

The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.
This commit restores this behaviour.
Fixes the test suites to consistently use mbedtls_fprintf to output to
stdout or stderr.
Also redirects output from the tests to /dev/null to avoid confusing
output if the test suite code or library outputs anything to stdout.
Minor fixes following review including:
* formatting changes including indentation and code style
* corrections
* removal of debug code
* clarification of code through variable renaming
* memory leak
* compiler warnings
The library/net.c and its corresponding include/mbedtls/net.h file are
renamed to library/net_sockets.c and include/mbedtls/net_sockets.h
respectively. This is to avoid naming collisions in projects which also
have files with the common name 'net'.

Changes to allow the entropy tests to work for configurations without an
entropy seed file (MBEDTLS_ENTROPY_NV_SEED), and with no entropy sources
configured (MBEDTLS_TEST_NULL_ENTROPY).
In some tests in ssl-opt.sh the client finishes sooner and the server
gets killed before it could reach certain errors. Consequently the
the script doesn't find the error it is looking for and the test fails.
To resolve this issue, we introduce a per-test option to wait after the
client finishes.
Instead of polling the hardware entropy source a single time and
comparing the output with itself, the source is polled at least twice
and make sure that the separate outputs are different.
The self test is a quick way to check at startup whether the entropy
sources are functioning correctly. The self test only polls 8 bytes
from the default entropy source and performs the following checks:
- The bytes are not all 0x00 or 0xFF.
- The hardware does not return an error when polled.
- The entropy does not provide data in a patter. Only check pattern
at byte, word and long word sizes.
In the test script tests/scripts/all.sh the armcc build is a baremetal build
and doesn't use MBEDTLS_HAVE_TIME therefore the test configuration
MBEDTLS_PLATFORM_TIME_ALT which is dependent on it must be unset.
The test script tests/scripts/all.sh exits on first error, although it also
attempted to redirect error output from armcc and then output it after armcc
had completed. This never occurred because as soon as armcc failed the script
would end and the redirected output wouldn't be displayed.
This change removes that redirection.
* Add script to print build environment info.
The new script is also included in:
- all.sh
- basic-build-test.sh
* Tidy up environment reporting script.
Changes include:
- making the echo calls portable
- removing unnecessary brackets
- using more efficient checks for the existance of commands
- correcting typos and copyright year
* Update references to output_env.sh
MBEDTLS_ENTROPY_NV_SEED is dependent on platform code unless an
alternative implementation is provided, therefore needs to be disabled
in the disabled filesystem IO build.
A standard 'test' that writes a seed file is added so that regular tests
still can succeed. This is in lieu of a 'SUITE_PRE_CODE' kind of
arrangement where a suite can run code before (and after) all other code
runs.
A test is added that checks if we can read and write the standard NV
seed file
A test is added that actually checks if the entropy and seed file values
that are the result of just using the NV seed are the same as the manual
calculation.
Running valgrind on: "DTLS client reconnect from same port: reconnect,
nbio" results in timeouts.
New version added that runs only under valgrind. Original only runs when
valgrind is not used
The glibc package recently enabled compressed debug symbols but valgrind doesn't
support them yet.
Results in messages like:
--14923-- WARNING: Serious error when reading debug info
--14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so:
--14923-- Ignoring non-Dwarf2/3/4 block in .debug_info
First line has 'error' in it which triggers some of the ssl-opt tests
The configuration MBEDTLS_MEMORY_BACKTRACE is intended for debug and
is not necessary for test coverage. Because it causes timing problems
in some tests the configuration has been removed as it's not present in
equivalent tests in the all.sh test script.
In order to reduce debugging time, allows you to only run interesting
tests (by number) from the commandline.
e.g. the command 'tests/ssl-opt.sh -n 246,258' will only run test 246
and 258 (as per the number in the log file names)
For a start, they don't even compile with Visual Studio due to strcasecmp
being missing. Secondly, on Windows Perl scripts aren't executable and have
to be run using the Perl interpreter directly; thankfully CMake is able to
find cygwin Perl straight away without problems.

The commit adds to the generate_code.pl script support to add #line directives
to generated code to allow build breaks to be more easily found from the
generated code.
Added a verbose option to the generated test suites which can list the
dependencies not met for skipped test cases.
Also clarifies internal interfaces between the main_test.function and test code,
and fixed a bug on calculating available tests in run-test-suites.pl.
Previously the test worked on the default configuration which missed deprecated
or legacy features. This change tests the full configuration and all available
tests.
This contains two fixes:
* CFLAGS symbol wasn't being exported so wasn't being used in the build
* Absence of a clean build meant the build could be made with existing
object code that may not have code coverage instrumentation
Following fixes:
* In the test script, 'basic-build-test.sh', the total number of functions had
a broken RE, and was picking up the number of tested functions.
* Titles of tests was misleading
* The 'run-test-suites.pl' script was mistaking dSYM directories as test
suites to be executed.
The main goal with these tests is to test the bug in question and
they are not meant to test the entire PKCS#1 v1.5 behaviour. To
achieve full test coverage, further test cases are needed.
Restructed test suite helper and main code to support tests suite helper
functions, changed C++ comments to C-style, and made the generated
source code more navigable.
Added to generate_code.pl:
- support for per test suite helper functions
- description of the structure of the files the script uses to construct
the test suite file
- delimiters through the source code to make the machine generated code
easier to understand
This re-introduces the apidoc with full config.h, but hopefully with the race
conditions and other issues that the previous implementation had.
Adapt doxygen test script to use that new script, and also check for errors
in addition to warnings while at it.
Apparently travis has an old version of doxygen that doesn't know all tags in
our config. That's not something we care about, we only want to know about
warnings in our doxygen content
On my machine, that reduces running time from about 30 minutes to less than 10
minutes, while maintaining a good probability of catching the most likely
issues in practice.
armar doesn't understand the syntax without dash. OTOH, the syntax with dash
is the only one specified by POSIX, and it's accepted by GNU ar, BSD ar (as
bundled with OS X) and armar, so it looks like the most portable syntax.

This extension is quite costly to generate, and we don't want to re-do it
again when the server performs a DTLS HelloVerify. So, cache the result the
first time and re-use if/when we build a new ClientHello.
Note: re-send due to timeouts are different, as the whole message is cached
already, so they don't need any special support.
Let the client retry longer, to make sure the server will time out before the
client gives up. Make it really longer to get a deterministic client exit
status (make sure it has time to reconnect after the server timeout).
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).
closes#220
As we're about to change the chain construction logic, we want to make sure
the callback will still be called exactly when it should, and not on the
(upcoming) ignored certs in the chain.
Tends to cause spurious failures on buildbots due to peer timing out.
Anyway, those tests are mainly for interop, any memory error is most likely
catched by some earlier self-op test. (Also, we'll run these tests with ASan
anyway.)
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.
Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.
see #257
Apparently openssl s_server does not flush stdout, anyway sometimes the client
receives the reply and exits, thus terminating the test, before is request is
visible on the server's stdout. So, just don't check that, checking the
client's output and exit code is already enough.
Retry one time in case we have a client timeout. These should be fairly rare
but still happen from time to time with udp_proxy tests which is annoying, and
until now has never indicated an actual issue.
Rather than flat-out die when we can't see the server started with lsof, just
stop waiting and try to go ahead with the test. Maybe it'll work if there was
a problem with lsof, most probably it will fail, but at least we'll have the
log, and the results of the following tests.
Note: date +%s isn't POSIX, but it works at least on Linux, Darwin/FreeBSD and
OpenBSD, which should be good enough for a test script.
This is not required nor recommended by the protocol, and it's a layering
violation, but it's a know flaw in the protocol that you can't detect a PSK
auth error in any other way, so it is probably the right thing to do.
closes#227
x509_get_name() does not make defensive copies of strings in its input (which
is OK as usually the caller will have made a copy already), so we shouldn't
reuse its input buffer as an output while "parsed" is still alive.
Our Windows implementation based on vsnprintf_s( ..., _TRUNCATE ) sometimes
writes *two* terminating NULLs. Allow for that, but obviously bytes past the
end of the buffer mustn't be touched.
Due to the recent change about entropy sources strength, it is no longer
acceptable to just disable the platform source. So, instead "fix" it so that
it is clear to MemSan that memory is initialized.
I tried __attribute__((no_sanitize_memory)) and MemSan's blacklist file, but
couldn't seem to get them to work.
- Added in each tests program to be sure they are run (putting them in a test
suite/function specific to the platform layer would cause them to be skipped
when PLATFORM_C is not defined).
- Platforms have already moved from a standard to a broken snprintf in the
past [1], so make sure to catch that if it ever happens again.
