Adam Langley 3fbc298104 Only allow ephemeral RSA keys in export ciphersuites.
OpenSSL clients would tolerate temporary RSA keys in non-export ciphersuites.
It also had an option SSL_OP_EPHEMERAL_RSA which enabled this server side.
Remove both options as they are a protocol violation.

# BoringSSL API Conventions
This document describes conventions for BoringSSL APIs. The [style
guide](/STYLE.md) also includes guidelines, but this document is targeted at
both API consumers and developers.
## Documentation
All supported public APIs are documented in the public header files, found in
`include/openssl`. The API documentation is also available
[online](https://commondatastorage.googleapis.com/chromium-boringssl-docs/headers.html).
Some headers lack documention comments. These are functions and structures from
OpenSSL's legacy ASN.1, X.509, and PEM implementation. If possible, avoid using
them. These are left largely unmodified from upstream and are retained only for
compatibility with existing OpenSSL consumers.
## Forward declarations
Do not write `typedef struct foo_st FOO` or try otherwise to define BoringSSL's
types. Including `openssl/base.h` (or `openssl/ossl_typ.h` for consumers who
wish to be OpenSSL-compatible) will forward-declare each type without importing
the rest of the library or invasive macros.
## Error-handling
Most functions in BoringSSL may fail, either due to allocation failures or input
errors. Functions which return an `int` typically return one on success and zero
on failure. Functions which return a pointer typically return `NULL` on failure.
However, due to legacy constraints, some functions are more complex. Consult the
API documentation before using a function.
On error, most functions also push errors on the error queue, an `errno`-like
mechanism. See the documentation for
[err.h](https://commondatastorage.googleapis.com/chromium-boringssl-docs/err.h.html)
for more details.
As with `errno`, callers must test the function's return value, not the error
queue to determine whether an operation failed. Some codepaths may not interact
with the error queue, and the error queue may have state from a previous failed
operation.
When ignoring a failed operation, it is recommended to call `ERR_clear_error` to
avoid the state interacting with future operations. Failing to do so should not
affect the actual behavior of any functions, but may result in errors from both
operations being mixed in error logging. We hope to
[improve](https://bugs.chromium.org/p/boringssl/issues/detail?id=38) this
situation in the future.
Where possible, avoid conditioning on specific reason codes and limit usage to
logging. The reason codes are very specific and may change over time.
## Memory allocation
BoringSSL allocates memory via `OPENSSL_malloc`, found in `mem.h`. Use
`OPENSSL_free`, found in the same header file, to release it. BoringSSL
functions will fail gracefully on allocation error, but it is recommended to use
a `malloc` implementation that `abort`s on failure.
## Object initialization and cleanup
BoringSSL defines a number of structs for use in its APIs. It is a C library,
so the caller is responsible for ensuring these structs are properly
initialized and released. Consult the documentation for a module for the
proper use of its types. Some general conventions are listed below.
### Heap-allocated types
Some types, such as `RSA`, are heap-allocated. All instances will be allocated
and returned from BoringSSL's APIs. It is an error to instantiate a heap-
allocated type on the stack or embedded within another object.
Heap-allocated types may have functioned named like `RSA_new` which allocates a
fresh blank `RSA`. Other functions may also return newly-allocated instances.
For example, `RSA_parse_public_key` is documented to return a newly-allocated
`RSA` object.
Heap-allocated objects must be released by the corresponding free function,
named like `RSA_free`. Like C's `free` and C++'s `delete`, all free functions
internally check for `NULL`. Consumers are not required to check for `NULL`
before calling.
A heap-allocated type may be reference-counted. In this case, a function named
like `RSA_up_ref` will be available to take an additional reference count. The
free function must be called to decrement the reference count. It will only
release resources when the final reference is released. For OpenSSL
compatibility, these functions return `int`, but callers may assume they always
successfully return one because reference counts use saturating arithmetic.
C++ consumers are recommended to use `bssl::UniquePtr` to manage heap-allocated
objects. `bssl::UniquePtr<T>`, like other types, is forward-declared in
`openssl/base.h`. Code that needs access to the free functions, such as code
which destroys a `bssl::UniquePtr`, must include the corresponding module's
header. (This matches `std::unique_ptr`'s relationship with forward
declarations.) Note, despite the name, `bssl::UniquePtr` is also used with
reference-counted types. It owns a single reference to the object. To take an
additional reference, use the `bssl::UpRef` function, which will return a
separate `bssl::UniquePtr`.
### Stack-allocated types
Other types in BoringSSL are stack-allocated, such as `EVP_MD_CTX`. These
types may be allocated on the stack or embedded within another object.
However, they must still be initialized before use.
Every stack-allocated object in BoringSSL has a *zero state*, analogous to
initializing a pointer to `NULL`. In this state, the object may not be
completely initialized, but it is safe to call cleanup functions. Entering the
zero state cannot fail. (It is usually `memset(0)`.)
The function to enter the zero state is named like `EVP_MD_CTX_init` or
`CBB_zero` and will always return `void`. To release resources associated with
the type, call the cleanup function, named like `EVP_MD_CTX_cleanup`. The
cleanup function must be called on all codepaths, regardless of success or
failure. For example:
uint8_t md[EVP_MAX_MD_SIZE];
unsigned md_len;
EVP_MD_CTX ctx;
EVP_MD_CTX_init(&ctx); /* Enter the zero state. */
int ok = EVP_DigestInit_ex(&ctx, EVP_sha256(), NULL) &&
EVP_DigestUpdate(&ctx, "hello ", 6) &&
EVP_DigestUpdate(&ctx, "world", 5) &&
EVP_DigestFinal_ex(&ctx, md, &md_len);
EVP_MD_CTX_cleanup(&ctx); /* Release |ctx|. */
Note that `EVP_MD_CTX_cleanup` is called whether or not the `EVP_Digest*`
operations succeeded. More complex C functions may use the `goto err` pattern:
int ret = 0;
EVP_MD_CTX ctx;
EVP_MD_CTX_init(&ctx);
if (!some_other_operation()) {
goto err;
}
uint8_t md[EVP_MAX_MD_SIZE];
unsigned md_len;
if (!EVP_DigestInit_ex(&ctx, EVP_sha256(), NULL) ||
!EVP_DigestUpdate(&ctx, "hello ", 6) ||
!EVP_DigestUpdate(&ctx, "world", 5) ||
!EVP_DigestFinal_ex(&ctx, md, &md_len) {
goto err;
}
ret = 1;
err:
EVP_MD_CTX_cleanup(&ctx);
return ret;
Note that, because `ctx` is set to the zero state before any failures,
`EVP_MD_CTX_cleanup` is safe to call even if the first operation fails before
`EVP_DigestInit_ex`. However, it would be illegal to move the `EVP_MD_CTX_init`
below the `some_other_operation` call.
As a rule of thumb, enter the zero state of stack-allocated structs in the
same place they are declared.
C++ consumers are recommended to use the wrappers named like
`bssl::ScopedEVP_MD_CTX`, defined in the corresponding module's header. These
wrappers are automatically initialized to the zero state and are automatically
cleaned up.
### Data-only types
A few types, such as `SHA_CTX`, are data-only types and do not require cleanup.
These are usually for low-level cryptographic operations. These types may be
used freely without special cleanup conventions.
### Ownership and lifetime
When working with allocated objects, it is important to think about *ownership*
of each object, or what code is responsible for releasing it. This matches the
corresponding notion in higher-level languages like C++ and Rust.
Ownership applies to both uniquely-owned types and reference-counted types. For
the latter, ownership means the code is responsible for releasing one
reference. Note a *reference* in BoringSSL refers to an increment (and eventual
decrement) of an object's reference count, not `T&` in C++. Thus, to "take a
reference" means to increment the reference count and take ownership of
decrementing it.
As BoringSSL's APIs are primarily in C, ownership and lifetime obligations are
not rigorously annotated in the type signatures or checked at compile-time.
Instead, they are described in
[API documentation](https://commondatastorage.googleapis.com/chromium-boringssl-docs/headers.html).
This section describes some conventions.
Unless otherwise documented, functions do not take ownership of pointer
arguments. The pointer typically must remain valid for the duration of the
function call. The function may internally copy information from the argument or
take a reference, but the caller is free to release its copy or reference at any
point after the call completes.
A function may instead be documented to *take* or *transfer* ownership of a
pointer. The caller must own the object before the function call and, after
transfer, no longer owns it. As a corollary, the caller may no longer reference
the object without a separate guarantee on the lifetime. The function may even
release the object before returning. Callers that wish to independently retain a
transfered object must therefore take a reference or make a copy before
transferring. Callers should also take note of whether the function is
documented to transfer pointers unconditionally or only on success. Unlike C++
and Rust, functions in BoringSSL typically only transfer on success.
Likewise, output pointers may be owning or non-owning. Unless otherwise
documented, functions output non-owning pointers. The caller is not responsible
for releasing the output pointer, but it must not use the pointer beyond its
lifetime. The pointer may be released when the parent object is released or even
sooner on state change in the parent object.
If documented to output a *newly-allocated* object or a *reference* or *copy* of
one, the caller is responsible for releasing the object when it is done.
By convention, functions named `get0` return non-owning pointers. Functions
named `new` or `get1` return owning pointers. Functions named `set0` take
ownership of arguments. Functions named `set1` do not. They typically take a
reference or make a copy internally. These names originally referred to the
effect on a reference count, but the convention applies equally to
non-reference-counted types.
API documentation may also describe more complex obligations. For instance, an
object may borrow a pointer for longer than the duration of a single function
call, in which case the caller must ensure the lifetime extends accordingly.
Memory errors are one of the most common and dangerous bugs in C and C++, so
callers are encouraged to make use of tools such as
[AddressSanitizer](https://clang.llvm.org/docs/AddressSanitizer.html) and
higher-level languages.
## Thread safety
BoringSSL is internally aware of the platform threading library and calls into
it as needed. Consult the API documentation for the threading guarantees of
particular objects. In general, stateless reference-counted objects like `RSA`
or `EVP_PKEY` which represent keys may typically be used from multiple threads
simultaneously, provided no thread mutates the key.

# How to change BoringSSL's API
BoringSSL has more flexibility in changing things than many other library projects because we have a reasonable idea of who our users are. Still, breaking changes require some care. We depend on tight feedback loops with our consumers so that we can learn about mistakes and fix them. For that to work, updating BoringSSL must be smooth.
Ultimately, the strategy for each breaking change is decided on a case-by-case basis. This document provides guidelines and techniques to help with a smooth transition.
## Breakage risk
Traditionally, breaking changes are defined in terms of API or ABI surface. Exposed symbols and type signatures cannot change, etc. But this is a poor approximation of the true impact. Removing an API may not a breaking change if no one is using it. Conversely, [Hyrum's Law](http://www.hyrumslaw.com/) applies. Fixing a bug may be a breaking change for some consumer which was depending on that bug.
Thus, we do not think about whether a change is formally a breaking change, but about the *risk* of it breaking someone.
Some changes, such as internal cleanups or bug-fixes, are low risk and do not need special measures. Any problems can be handled when the affected consumer updates BoringSSL and notices.
Other changes, such as removing an API, forbidding some edge case, or adjusting some behavior, are more likely to break things. To help the consumer triage any resulting failures, include some text in the commit message, prefixed by `Update-Note: `. This can include what this change may break and instructions on how to fix the issue.
## Code Search
The vast majority of BoringSSL consumers are conveniently indexed in various Code Search instances. This can predict the impact of a risky change and identify code to fix ahead of time. The document &ldquo;How to Code Search&rdquo; in the (Google-only) [go/boringssl-folder](https://goto.google.com/boringssl-folder) includes notes on this.
## Evaluate a change's cost
If some change has high cost (from having to fix consumers) and relatively little benefit to BoringSSL, it may not be worth the trouble. For instance, it is likely not worth removing a small compatibility function in the corner of the library that is easily dropped by the static linker.
Conversely, a change that leads to a major improvement to all BoringSSL consumers, at the cost of fixing one or two consumers, is typically worth it.
## Fixing consumers
If code search reveals call sites that are definitely going to break, prefer to handle these before making the change. While unexpected breakage is always possible, we generally consider it the responsibility of the developer or group making a change to handle impact of that change. Teams are generally unhappy to be surprised by new migration work but happy to have migration work done for them.
In most cases, this is straightforward:
1. Add the replacement API.
2. As the replacement API enters each consuming repository, migrate callers to it.
3. Remove the original API once all consumers have been migrated.
The removal should still include an `Update-Note` tag, in case some were missed.
In some cases, this kind of staged approach is not feasible: perhaps the same code cannot simultaneously work before and after the change, or perhaps there are too many different versions in play. For instance, [Conscrypt](https://github.com/google/conscrypt) feeds into three different repositories. The GitHub repository consumes BoringSSL's `master` branch directly. It is pushed into Android, where it consumes Android's `external/boringssl`. Yet another copy is pushed into the internal repository, where it consumes that copy of BoringSSL. As each of these Conscrypts are updated independently from their corresponding BoringSSLs, Conscrypt upstream cannot rely on a new BoringSSL API until it is present in all copies of BoringSSL its downstreams rely on.
In that case, a multi-sided change may be more appropriate:
1. Upload the breaking change to Gerrit, but do not submit it yet. Increment the `BORINGSSL_API_VERSION` symbol.
2. Update the consuming repository with `#if BORINGSSL_API_VERSION < N` preprocessor logic. Leave a comment to remove this later, linking to your BoringSSL change.
3. When the `BORINGSSL_API_VERSION` check has propagated to relevant copies of the consuming repository, submit the BoringSSL change.
4. When the BoringSSL change has propagated to relevant copies of BoringSSL, remove the staging logic from the consumer.
Finally, in some cases, the consumer's change may be committed atomically with the BoringSSL update. This can only be done for code which only consumes one instance of BoringSSL (so the Conscrypt example above is not eligible). Check with that project's maintainer first or, better, be that project's maintainer.
If more complex changes are needed in some consumer, communicate with the relevant maintainers to plan the transition.
## Fail early, fail closed
When breaking changes do occur, they should fail as early and as detectably as possible.
Ideally, problematic consumers fail to compile. Prefer to remove functions completely over leaving an always failing stub function. Sometimes this is not possible due to other consumers, particularly bindings libraries. Alternatively, if a stub function can be reasonably justified as still satisfying the API constraints, consider adding one to improve compatibility. For example, BoringSSL has many no-op stubs corresponding to OpenSSL's many initialization functions.
If some parameter now must be `NULL`, change the type to an opaque struct pointer. Consumers passing non-`NULL` pointers will then fail to compile.
If breaking the compile is not feasible, break at runtime, in the hope that consumers have some amount of test coverage. When doing so, try to fail on the common case. In particular, do not rely on consumers adequately testing or even checking for failure cases. One strategy is to bring the object into a &ldquo;poison&rdquo; state: if an illegal operation occurs, set a flag to fail all subsequent ones.
In other functions, it may be appropriate to simply call `abort()`.
## Unexpected breakage
While we try to avoid breaking things, sometimes things unexpectedly break. Depending on the impact, we may fix the consumer, make a small fix to BoringSSL, or revert the change to either try again later or revise the approach.
If we do not ultimately fix the consumer, add a test in BoringSSL to capture the unexpected API contract, so future regressions are caught quickly.
## Canary changes and bake time
When planning a large project that depends on a breaking change, prefer to make the breaking change first&mdash;before committing larger changes. Or, when changing toolchain or language requirements, add a small instance of the dependency somewhere first then wait a couple of weeks for the change to appear in consumers. This ensures that reverting the change is still feasible if necessary.
While we rely on a tight feedback loop with our consumers, there are a few consumers which update less frequently. For extremely risky changes, such as introducing C++ to a target, it may be prudent to wait much longer.
## Third-party code
In many cases, we are interested in changing behavior which came from OpenSSL. OpenSSL's API surface is huge, but only a small subset is actually used. So we can and occasionally do change these behaviors. This is more complex than changing BoringSSL-only behavior due to third-party code.
We use BoringSSL with many third-party projects that normally use OpenSSL. Generally, we consider this our burden to make this work and do not encourage external projects to depend on BoringSSL. While we can and do maintain patches for this as necessary, it has overhead and so the cost of breaking third-party code is higher.
We lean fairly strongly towards making changes to BoringSSL over patching third-party code, unless the third-party change fixes a security problem.
Additionally, changing an OpenSSL API will not only affect third-party code we use today, but also any third-party code we use in the future. Thus Code Search is less useful as an absolute predictor, and the various other considerations in this document are more important.
If the patch to support a BoringSSL change can be generally useful to the third-party project, send it upstream. For instance, it may use the APIs better, clean up code, or help support newer versions of OpenSSL. In general, we try to target compatibility with &ldquo;most&rdquo; &ldquo;well-behaved&rdquo; OpenSSL consumers.
Finally, if some particular OpenSSL API or pattern is problematic to BoringSSL, it is likely problematic to OpenSSL too. Consider filing a bug with them to suggest a change, either in new code going forward or for the next API break. OpenSSL's release cycles and feedback loops are much longer than BoringSSL's, so this is usually not immediately useful, but it keeps the ecosystem moving in the right direction.

# Building BoringSSL
## Build Prerequisites
The standalone CMake build is primarily intended for developers. If embedding
BoringSSL into another project with a pre-existing build system, see
[INCORPORATING.md](/INCORPORATING.md).
Unless otherwise noted, build tools must at most five years old, matching
[Abseil guidelines](https://abseil.io/about/compatibility). If in doubt, use the
most recent stable version of each tool.
* [CMake](https://cmake.org/download/) 3.0 or later is required.
* A recent version of Perl is required. On Windows,
[Active State Perl](http://www.activestate.com/activeperl/) has been
reported to work, as has MSYS Perl.
[Strawberry Perl](http://strawberryperl.com/) also works but it adds GCC
to `PATH`, which can confuse some build tools when identifying the compiler
(removing `C:\Strawberry\c\bin` from `PATH` should resolve any problems).
If Perl is not found by CMake, it may be configured explicitly by setting
`PERL_EXECUTABLE`.
* Building with [Ninja](https://ninja-build.org/) instead of Make is
recommended, because it makes builds faster. On Windows, CMake's Visual
Studio generator may also work, but it not tested regularly and requires
recent versions of CMake for assembly support.
* On Windows only, [NASM](https://www.nasm.us/) is required. If not found
by CMake, it may be configured explicitly by setting
`CMAKE_ASM_NASM_COMPILER`.
* C and C++ compilers with C++11 support are required. On Windows, MSVC 14
(Visual Studio 2015) or later with Platform SDK 8.1 or later are supported.
Recent versions of GCC (4.8+) and Clang should work on non-Windows
platforms, and maybe on Windows too.
* The most recent stable version of [Go](https://golang.org/dl/) is required.
Note Go is exempt from the five year support window. If not found by CMake,
the go executable may be configured explicitly by setting `GO_EXECUTABLE`.
* On x86_64 Linux, the tests have an optional
[libunwind](https://www.nongnu.org/libunwind/) dependency to test the
assembly more thoroughly.
## Building
Using Ninja (note the 'N' is capitalized in the cmake invocation):
mkdir build
cd build
cmake -GNinja ..
ninja
Using Make (does not work on Windows):
mkdir build
cd build
cmake ..
make
You usually don't need to run `cmake` again after changing `CMakeLists.txt`
files because the build scripts will detect changes to them and rebuild
themselves automatically.
Note that the default build flags in the top-level `CMakeLists.txt` are for
debugging—optimisation isn't enabled. Pass `-DCMAKE_BUILD_TYPE=Release` to
`cmake` to configure a release build.
If you want to cross-compile then there is an example toolchain file for 32-bit
Intel in `util/`. Wipe out the build directory, recreate it and run `cmake` like
this:
cmake -DCMAKE_TOOLCHAIN_FILE=../util/32-bit-toolchain.cmake -GNinja ..
If you want to build as a shared library, pass `-DBUILD_SHARED_LIBS=1`. On
Windows, where functions need to be tagged with `dllimport` when coming from a
shared library, define `BORINGSSL_SHARED_LIBRARY` in any code which `#include`s
the BoringSSL headers.
In order to serve environments where code-size is important as well as those
where performance is the overriding concern, `OPENSSL_SMALL` can be defined to
remove some code that is especially large.
See [CMake's documentation](https://cmake.org/cmake/help/v3.4/manual/cmake-variables.7.html)
for other variables which may be used to configure the build.
### Building for Android
It's possible to build BoringSSL with the Android NDK using CMake. Recent
versions of the NDK include a CMake toolchain file which works with CMake 3.6.0
or later. This has been tested with version r16b of the NDK.
Unpack the Android NDK somewhere and export `ANDROID_NDK` to point to the
directory. Then make a build directory as above and run CMake like this:
cmake -DANDROID_ABI=armeabi-v7a \
-DCMAKE_TOOLCHAIN_FILE=${ANDROID_NDK}/build/cmake/android.toolchain.cmake \
-DANDROID_NATIVE_API_LEVEL=16 \
-GNinja ..
Once you've run that, Ninja should produce Android-compatible binaries. You
can replace `armeabi-v7a` in the above with `arm64-v8a` and use API level 21 or
higher to build aarch64 binaries.
For other options, see the documentation in the toolchain file.
To debug the resulting binaries on an Android device with `gdb`, run the
commands below. Replace `ARCH` with the architecture of the target device, e.g.
`arm` or `arm64`.
adb push ${ANDROID_NDK}/prebuilt/android-ARCH/gdbserver/gdbserver \
/data/local/tmp
adb forward tcp:5039 tcp:5039
adb shell /data/local/tmp/gdbserver :5039 /path/on/device/to/binary
Then run the following in a separate shell. Replace `HOST` with the OS and
architecture of the host machine, e.g. `linux-x86_64`.
${ANDROID_NDK}/prebuilt/HOST/bin/gdb
target remote :5039 # in gdb
### Building for iOS
To build for iOS, pass `-DCMAKE_OSX_SYSROOT=iphoneos` and
`-DCMAKE_OSX_ARCHITECTURES=ARCH` to CMake, where `ARCH` is the desired
architecture, matching values used in the `-arch` flag in Apple's toolchain.
Passing multiple architectures for a multiple-architecture build is not
supported.
### Building with Prefixed Symbols
BoringSSL's build system has experimental support for adding a custom prefix to
all symbols. This can be useful when linking multiple versions of BoringSSL in
the same project to avoid symbol conflicts.
In order to build with prefixed symbols, the `BORINGSSL_PREFIX` CMake variable
should specify the prefix to add to all symbols, and the
`BORINGSSL_PREFIX_SYMBOLS` CMake variable should specify the path to a file
which contains a list of symbols which should be prefixed (one per line;
comments are supported with `#`). In other words, `cmake ..
-DBORINGSSL_PREFIX=MY_CUSTOM_PREFIX
-DBORINGSSL_PREFIX_SYMBOLS=/path/to/symbols.txt` will configure the build to add
the prefix `MY_CUSTOM_PREFIX` to all of the symbols listed in
`/path/to/symbols.txt`.
It is currently the caller's responsibility to create and maintain the list of
symbols to be prefixed. Alternatively, `util/read_symbols.go` reads the list of
exported symbols from a `.a` file, and can be used in a build script to generate
the symbol list on the fly (by building without prefixing, using
`read_symbols.go` to construct a symbol list, and then building again with
prefixing).
This mechanism is under development and may change over time. Please contact the
BoringSSL maintainers if making use of it.
## Known Limitations on Windows
* Versions of CMake since 3.0.2 have a bug in its Ninja generator that causes
yasm to output warnings
yasm: warning: can open only one input file, only the last file will be processed
These warnings can be safely ignored. The cmake bug is
http://www.cmake.org/Bug/view.php?id=15253.
* CMake can generate Visual Studio projects, but the generated project files
don't have steps for assembling the assembly language source files, so they
currently cannot be used to build BoringSSL.
## Embedded ARM
ARM, unlike Intel, does not have an instruction that allows applications to
discover the capabilities of the processor. Instead, the capability information
has to be provided by the operating system somehow.
By default, on Linux-based systems, BoringSSL will try to use `getauxval` and
`/proc` to discover the capabilities. But some environments don't support that
sort of thing and, for them, it's possible to configure the CPU capabilities at
compile time.
On iOS or builds which define `OPENSSL_STATIC_ARMCAP`, features will be
determined based on the `__ARM_NEON__` and `__ARM_FEATURE_CRYPTO` preprocessor
symbols reported by the compiler. These values are usually controlled by the
`-march` flag. You can also define any of the following to enable the
corresponding ARM feature.
* `OPENSSL_STATIC_ARMCAP_NEON`
* `OPENSSL_STATIC_ARMCAP_AES`
* `OPENSSL_STATIC_ARMCAP_SHA1`
* `OPENSSL_STATIC_ARMCAP_SHA256`
* `OPENSSL_STATIC_ARMCAP_PMULL`
Note that if a feature is enabled in this way, but not actually supported at
run-time, BoringSSL will likely crash.
## Binary Size
The implementations of some algorithms require a trade-off between binary size
and performance. For instance, BoringSSL's fastest P-256 implementation uses a
148 KiB pre-computed table. To optimize instead for binary size, pass
`-DOPENSSL_SMALL=1` to CMake or define the `OPENSSL_SMALL` preprocessor symbol.
# Running Tests
There are two sets of tests: the C/C++ tests and the blackbox tests. For former
are built by Ninja and can be run from the top-level directory with `go run
util/all_tests.go`. The latter have to be run separately by running `go test`
from within `ssl/test/runner`.
Both sets of tests may also be run with `ninja -C build run_tests`, but CMake
3.2 or later is required to avoid Ninja's output buffering.

Want to contribute? Great! First, read this page (including the small print at the end).
### Before you contribute
Before we can use your code, you must sign the
[Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual)
(CLA), which you can do online. The CLA is necessary mainly because you own the
copyright to your changes, even after your contribution becomes part of our
codebase, so we need your permission to use and distribute your code. We also
need to be sure of various other things—for instance that you'll tell us if you
know that your code infringes on other people's patents. You don't have to sign
the CLA until after you've submitted your code for review and a member has
approved it, but you must do it before we can put your code into our codebase.
Before you start working on a larger contribution, you should get in touch with
us first via email with your idea so that we can help out and possibly guide
you. Coordinating up front makes it much easier to avoid frustration later on.
### Code reviews
All submissions, including submissions by project members, require review. We
use [Gerrit](https://boringssl-review.googlesource.com) for this purpose.
#### Setup
If you have not done so on this machine, you will need to set up a password for
Gerrit. Sign in with a Google account, visit
[this link](https://boringssl.googlesource.com/), and click the "Generate
Password" link in the top right. You will also need to prepare your checkout to
[add Change-Ids](https://gerrit-review.googlesource.com/Documentation/cmd-hook-commit-msg.html)
on commit. Run:
curl -Lo .git/hooks/commit-msg https://boringssl-review.googlesource.com/tools/hooks/commit-msg
chmod u+x .git/hooks/commit-msg
#### Uploading changes
To upload a change, push it to the special `refs/for/master` target:
git push origin HEAD:refs/for/master
The output will then give you a link to the change. Add `agl@google.com` and
`davidben@google.com` as reviewers.
Pushing a commit with the same Change-Id as an existing change will upload a new
version of it. (Use the `git rebase` or `git commit --amend` commands.)

# Fuzz testing
Modern fuzz testers are very effective and we wish to use them to ensure that no silly bugs creep into BoringSSL.
We use Clang's [libFuzzer](http://llvm.org/docs/LibFuzzer.html) for fuzz testing and there are a number of fuzz testing functions in `fuzz/`. They are not built by default because they require that the rest of BoringSSL be built with some changes that make fuzzing much more effective, but are completely unsafe for real use.
In order to build the fuzz tests you will need at least Clang 6.0. Pass `-DFUZZ=1` on the CMake command line to enable building BoringSSL with coverage and AddressSanitizer, and to build the fuzz test binaries. You'll probably need to set the `CC` and `CXX` environment variables too, like this:
```
mkdir build
cd build
CC=clang CXX=clang++ cmake -GNinja -DFUZZ=1 ..
ninja
```
From the `build/` directory, you can then run the fuzzers. For example:
```
./fuzz/cert -max_len=10000 -jobs=32 -workers=32 ../fuzz/cert_corpus/
```
The arguments to `jobs` and `workers` should be the number of cores that you wish to dedicate to fuzzing. By default, libFuzzer uses the largest test in the corpus (or 64 if empty) as the maximum test case length. The `max_len` argument overrides this.
The recommended values of `max_len` for each test are:
| Test | `max_len` value |
|---------------|-----------------|
| `bn_div` | 384 |
| `bn_mod_exp` | 4096 |
| `cert` | 10000 |
| `client` | 20000 |
| `pkcs8` | 2048 |
| `privkey` | 2048 |
| `server` | 4096 |
| `session` | 8192 |
| `spki` | 1024 |
| `read_pem` | 512 |
| `ssl_ctx_api` | 256 |
These were determined by rounding up the length of the largest case in the corpus.
There are directories in `fuzz/` for each of the fuzzing tests which contain seed files for fuzzing. Some of the seed files were generated manually but many of them are “interesting” results generated by the fuzzing itself. (Where “interesting” means that it triggered a previously unknown path in the code.)
## Minimising the corpuses
When a large number of new seeds are available, it's a good idea to minimise the corpus so that different seeds that trigger the same code paths can be deduplicated.
In order to minimise all the corpuses, build for fuzzing and run `./fuzz/minimise_corpuses.sh`. Note that minimisation is, oddly, often not idempotent for unknown reasons.
## Fuzzer mode
When `-DFUZZ=1` is passed into CMake, BoringSSL builds with `BORINGSSL_UNSAFE_FUZZER_MODE` and `BORINGSSL_UNSAFE_DETERMINISTIC_MODE` defined. This modifies the library to be more friendly to fuzzers. If `BORINGSSL_UNSAFE_DETERMINISTIC_MODE` is set, BoringSSL will:
* Replace `RAND_bytes` with a deterministic PRNG. Call `RAND_reset_for_fuzzing()` at the start of fuzzers which use `RAND_bytes` to reset the PRNG state.
* Use a hard-coded time instead of the actual time.
Additionally, if `BORINGSSL_UNSAFE_FUZZER_MODE` is set, BoringSSL will:
* Modify the TLS stack to perform all signature checks (CertificateVerify and ServerKeyExchange) and the Finished check, but always act as if the check succeeded.
* Treat every cipher as the NULL cipher.
* Tickets are unencrypted and the MAC check is performed but ignored.
* renegotiation\_info checks are ignored.
This is to prevent the fuzzer from getting stuck at a cryptographic invariant in the protocol.
## TLS transcripts
The `client` and `server` corpora are seeded from the test suite. The test suite has a `-fuzzer` flag which mirrors the fuzzer mode changes above and a `-deterministic` flag which removes all non-determinism on the Go side. Not all tests pass, so `ssl/test/runner/fuzzer_mode.json` contains the necessary suppressions. The `run_tests` target will pass appropriate command-line flags.
There are separate corpora, `client_corpus_no_fuzzer_mode` and `server_corpus_no_fuzzer_mode`. These are transcripts for fuzzers with only `BORINGSSL_UNSAFE_DETERMINISTIC_MODE` defined. To build in this mode, pass `-DNO_FUZZER_MODE=1` into CMake. This configuration is run in the same way but without `-fuzzer` and `-shim-config` flags.
If both sets of tests pass, refresh the fuzzer corpora with `refresh_ssl_corpora.sh`:
```
cd fuzz
./refresh_ssl_corpora.sh /path/to/fuzzer/mode/build /path/to/non/fuzzer/mode/build
```

# Incorporating BoringSSL into a project
**Note**: if your target project is not a Google project then first read the
[main README](/README.md) about the purpose of BoringSSL.
## Bazel
If you are using [Bazel](https://bazel.build) then you can incorporate
BoringSSL as an external repository by using a commit from the
`master-with-bazel` branch. That branch is maintained by a bot from `master`
and includes the needed generated files and a top-level BUILD file.
For example:
git_repository(
name = "boringssl",
commit = "_some commit_",
remote = "https://boringssl.googlesource.com/boringssl",
)
You would still need to keep the referenced commit up to date if a specific
commit is referred to.
## Directory layout
Typically projects create a `third_party/boringssl` directory to put
BoringSSL-specific files into. The source code of BoringSSL itself goes into
`third_party/boringssl/src`, either by copying or as a
[submodule](https://git-scm.com/docs/git-submodule).
It's generally a mistake to put BoringSSL's source code into
`third_party/boringssl` directly because pre-built files and custom build files
need to go somewhere and merging these with the BoringSSL source code makes
updating things more complex.
## Build support
BoringSSL is designed to work with many different build systems. Currently,
different projects use [GYP](https://gyp.gsrc.io/),
[GN](https://gn.googlesource.com/gn/+/master/docs/quick_start.md),
[Bazel](https://bazel.build/) and [Make](https://www.gnu.org/software/make/) to
build BoringSSL, without too much pain.
The development build system is CMake and the CMake build knows how to
automatically generate the intermediate files that BoringSSL needs. However,
outside of the CMake environment, these intermediates are generated once and
checked into the incorporating project's source repository. This avoids
incorporating projects needing to support Perl and Go in their build systems.
The script [`util/generate_build_files.py`](/util/generate_build_files.py)
expects to be run from the `third_party/boringssl` directory and to find the
BoringSSL source code in `src/`. You should pass it a single argument: the name
of the build system that you're using. If you don't use any of the supported
build systems then you should augment `generate_build_files.py` with support
for it.
The script will pregenerate the intermediate files (see
[BUILDING.md](/BUILDING.md) for details about which tools will need to be
installed) and output helper files for that build system. It doesn't generate a
complete build script, just file and test lists, which change often. For
example, see the
[file](https://code.google.com/p/chromium/codesearch#chromium/src/third_party/boringssl/BUILD.generated.gni)
and
[test](https://code.google.com/p/chromium/codesearch#chromium/src/third_party/boringssl/BUILD.generated_tests.gni)
lists generated for GN in Chromium.
Generally one checks in these generated files alongside the hand-written build
files. Periodically an engineer updates the BoringSSL revision, regenerates
these files and checks in the updated result. As an example, see how this is
done [in Chromium](https://code.google.com/p/chromium/codesearch#chromium/src/third_party/boringssl/).
## Defines
BoringSSL does not present a lot of configurability in order to reduce the
number of configurations that need to be tested. But there are a couple of
\#defines that you may wish to set:
`OPENSSL_NO_ASM` prevents the use of assembly code (although it's up to you to
ensure that the build system doesn't link it in if you wish to reduce binary
size). This will have a significant performance impact but can be useful if you
wish to use tools like
[AddressSanitizer](http://clang.llvm.org/docs/AddressSanitizer.html) that
interact poorly with assembly code.
`OPENSSL_SMALL` removes some code that is especially large at some performance
cost.
## Symbols
You cannot link multiple versions of BoringSSL or OpenSSL into a single binary
without dealing with symbol conflicts. If you are statically linking multiple
versions together, there's not a lot that can be done because C doesn't have a
module system.
If you are using multiple versions in a single binary, in different shared
objects, ensure you build BoringSSL with `-fvisibility=hidden` and do not
export any of BoringSSL's symbols. This will prevent any collisions with other
verisons that may be included in other shared objects. Note that this requires
that all callers of BoringSSL APIs live in the same shared object as BoringSSL.
If you require that BoringSSL APIs be used across shared object boundaries,
continue to build with `-fvisibility=hidden` but define
`BORINGSSL_SHARED_LIBRARY` in both BoringSSL and consumers. BoringSSL's own
source files (but *not* consumers' source files) must also build with
`BORINGSSL_IMPLEMENTATION` defined. This will export BoringSSL's public symbols
in the resulting shared object while hiding private symbols. However note that,
as with a static link, this precludes dynamically linking with another version
of BoringSSL or OpenSSL.

# Porting from OpenSSL to BoringSSL
BoringSSL is an OpenSSL derivative and is mostly source-compatible, for the
subset of OpenSSL retained. Libraries ideally need little to no changes for
BoringSSL support, provided they do not use removed APIs. In general, see if the
library compiles and, on failure, consult the documentation in the header files
and see if problematic features can be removed.
BoringSSL's `OPENSSL_VERSION_NUMBER` matches the OpenSSL version it targets.
Version checks for OpenSSL should ideally work as-is in BoringSSL. BoringSSL
also defines upstream's `OPENSSL_NO_*` feature macros corresponding to removed
features. If the preprocessor is needed, use these version checks or feature
macros where possible, especially when patching third-party projects. Such
patches are more generally useful to OpenSSL consumers and thus more
appropriate to send upstream.
In some cases, BoringSSL-specific code may be necessary. Use the
`OPENSSL_IS_BORINGSSL` preprocessor macro in `#ifdef`s. However, first contact
the BoringSSL maintainers about the missing APIs. We will typically add
compatibility functions for convenience. In particular, *contact BoringSSL
maintainers before working around missing OpenSSL 1.1.0 accessors*. BoringSSL
was originally derived from OpenSSL 1.0.2 but now targets OpenSSL 1.1.0. Some
newer APIs may be missing but can be added on request. (Not all projects have
been ported to OpenSSL 1.1.0, so BoringSSL also remains largely compatible with
OpenSSL 1.0.2.)
The `OPENSSL_IS_BORINGSSL` macro may also be used to distinguish OpenSSL from
BoringSSL in configure scripts. Do not use the presence or absence of particular
symbols to detect BoringSSL.
Note: BoringSSL does *not* have a stable API or ABI. It must be updated with its
consumers. It is not suitable for, say, a system library in a traditional Linux
distribution. For instance, Chromium statically links the specific revision of
BoringSSL it was built against. Likewise, Android's system-internal copy of
BoringSSL is not exposed by the NDK and must not be used by third-party
applications.
## Major API changes
### Integer types
Some APIs have been converted to use `size_t` for consistency and to avoid
integer overflows at the API boundary. (Existing logic uses a mismash of `int`,
`long`, and `unsigned`.) For the most part, implicit casts mean that existing
code continues to compile. In some cases, this may require BoringSSL-specific
code, particularly to avoid compiler warnings.
Most notably, the `STACK_OF(T)` types have all been converted to use `size_t`
instead of `int` for indices and lengths.
### Reference counts and opaque types
Some external consumers increment reference counts directly by calling
`CRYPTO_add` with the corresponding `CRYPTO_LOCK_*` value. These APIs no longer
exist in BoringSSL. Instead, code which increments reference counts should call
the corresponding `FOO_up_ref` function, such as `EVP_PKEY_up_ref`.
BoringSSL also hides some structs which were previously exposed in OpenSSL
1.0.2, particularly in libssl. Use the relevant accessors instead.
Note that some of these APIs were added in OpenSSL 1.1.0, so projects which do
not yet support 1.1.0 may need additional `#ifdef`s. Projects supporting OpenSSL
1.1.0 should not require modification.
### Error codes
OpenSSL's errors are extremely specific, leaking internals of the library,
including even a function code for the function which emitted the error! As some
logic in BoringSSL has been rewritten, code which conditions on the error may
break (grep for `ERR_GET_REASON` and `ERR_GET_FUNC`). This danger also exists
when upgrading OpenSSL versions.
Where possible, avoid conditioning on the exact error reason. Otherwise, a
BoringSSL `#ifdef` may be necessary. Exactly how best to resolve this issue is
still being determined. It's possible some new APIs will be added in the future.
Function codes have been completely removed. Remove code which conditions on
these as it will break with the slightest change in the library, OpenSSL or
BoringSSL.
### `*_ctrl` functions
Some OpenSSL APIs are implemented with `ioctl`-style functions such as
`SSL_ctrl` and `EVP_PKEY_CTX_ctrl`, combined with convenience macros, such as
# define SSL_CTX_set_mode(ctx,op) \
SSL_CTX_ctrl((ctx),SSL_CTRL_MODE,(op),NULL)
In BoringSSL, these macros have been replaced with proper functions. The
underlying `_ctrl` functions have been removed.
For convenience, `SSL_CTRL_*` values are retained as macros to `doesnt_exist` so
existing code which uses them (or the wrapper macros) in `#ifdef` expressions
will continue to function. However, the macros themselves will not work.
Switch any `*_ctrl` callers to the macro/function versions. This works in both
OpenSSL and BoringSSL. Note that BoringSSL's function versions will be
type-checked and may require more care with types. See the end of this
document for a table of functions to use.
### HMAC `EVP_PKEY`s
`EVP_PKEY_HMAC` is removed. Use the `HMAC_*` functions in `hmac.h` instead. This
is compatible with OpenSSL.
### DSA `EVP_PKEY`s
`EVP_PKEY_DSA` is deprecated. It is currently still possible to parse DER into a
DSA `EVP_PKEY`, but signing or verifying with those objects will not work.
### DES
The `DES_cblock` type has been switched from an array to a struct to avoid the
pitfalls around array types in C. Where features which require DES cannot be
disabled, BoringSSL-specific codepaths may be necessary.
### TLS renegotiation
OpenSSL enables TLS renegotiation by default and accepts renegotiation requests
from the peer transparently. Renegotiation is an extremely problematic protocol
feature, so BoringSSL rejects peer renegotiations by default.
To enable renegotiation, call `SSL_set_renegotiate_mode` and set it to
`ssl_renegotiate_once` or `ssl_renegotiate_freely`. Renegotiation is only
supported as a client in TLS and the HelloRequest must be received at a
quiet point in the application protocol. This is sufficient to support the
common use of requesting a new client certificate between an HTTP request and
response in (unpipelined) HTTP/1.1.
Things which do not work:
* There is no support for renegotiation as a server. (Attempts by clients will
result in a fatal alert so that ClientHello messages cannot be used to flood
a server and escape higher-level limits.)
* There is no support for renegotiation in DTLS.
* There is no support for initiating renegotiation; `SSL_renegotiate` always
fails and `SSL_set_state` does nothing.
* Interleaving application data with the new handshake is forbidden.
* If a HelloRequest is received while `SSL_write` has unsent application data,
the renegotiation is rejected.
* Renegotiation does not participate in session resumption. The client will
not offer a session on renegotiation or resume any session established by a
renegotiation handshake.
* The server may not change its certificate in the renegotiation. This mitigates
the [triple handshake attack](https://mitls.org/pages/attacks/3SHAKE). Any new
stapled OCSP response and SCT list will be ignored. As no authentication state
may change, BoringSSL will not re-verify the certificate on a renegotiation.
Callbacks such as `SSL_CTX_set_custom_verify` will only run on the initial
handshake.
### Lowercase hexadecimal
BoringSSL's `BN_bn2hex` function uses lowercase hexadecimal digits instead of
uppercase. Some code may require changes to avoid being sensitive to this
difference.
### Legacy ASN.1 functions
OpenSSL's ASN.1 stack uses `d2i` functions for parsing. They have the form:
RSA *d2i_RSAPrivateKey(RSA **out, const uint8_t **inp, long len);
In addition to returning the result, OpenSSL places it in `*out` if `out` is
not `NULL`. On input, if `*out` is not `NULL`, OpenSSL will usually (but not
always) reuse that object rather than allocating a new one. In BoringSSL, these
functions are compatibility wrappers over a newer ASN.1 stack. Even if `*out`
is not `NULL`, these wrappers will always allocate a new object and free the
previous one.
Ensure that callers do not rely on this object reuse behavior. It is
recommended to avoid the `out` parameter completely and always pass in `NULL`.
Note that less error-prone APIs are available for BoringSSL-specific code (see
below).
### Memory allocation
OpenSSL provides wrappers `OPENSSL_malloc` and `OPENSSL_free` over the standard
`malloc` and `free`. Memory allocated by OpenSSL should be released with
`OPENSSL_free`, not the standard `free`. However, by default, they are
implemented directly using `malloc` and `free`, so code which mixes them up
usually works.
In BoringSSL, these functions maintain additional book-keeping to zero memory
on `OPENSSL_free`, so any mixups must be fixed.
## Optional BoringSSL-specific simplifications
BoringSSL makes some changes to OpenSSL which simplify the API but remain
compatible with OpenSSL consumers. In general, consult the BoringSSL
documentation for any functions in new BoringSSL-only code.
### Return values
Most OpenSSL APIs return 1 on success and either 0 or -1 on failure. BoringSSL
has narrowed most of these to 1 on success and 0 on failure. BoringSSL-specific
code may take advantage of the less error-prone APIs and use `!` to check for
errors.
### Initialization
OpenSSL has a number of different initialization functions for setting up error
strings and loading algorithms, etc. All of these functions still exist in
BoringSSL for convenience, but they do nothing and are not necessary.
The one exception is `CRYPTO_library_init`. In `BORINGSSL_NO_STATIC_INITIALIZER`
builds, it must be called to query CPU capabilities before the rest of the
library. In the default configuration, this is done with a static initializer
and is also unnecessary.
### Threading
OpenSSL provides a number of APIs to configure threading callbacks and set up
locks. Without initializing these, the library is not thread-safe. Configuring
these does nothing in BoringSSL. Instead, BoringSSL calls pthreads and the
corresponding Windows APIs internally and is always thread-safe where the API
guarantees it.
### ASN.1
BoringSSL is in the process of deprecating OpenSSL's `d2i` and `i2d` in favor of
new functions using the much less error-prone `CBS` and `CBB` types.
BoringSSL-only code should use those functions where available.
## Replacements for `CTRL` values
When porting code which uses `SSL_CTX_ctrl` or `SSL_ctrl`, use the replacement
functions below. If a function has both `SSL_CTX` and `SSL` variants, only the
`SSL_CTX` version is listed.
Note some values correspond to multiple functions depending on the `larg`
parameter.

`SSL_CTRL_SET_TMP_RSA_CB` | `SSL_CTX_set_tmp_rsa_callback` is equivalent, but [*do not use this function*](https://freakattack.com/). (It is a no-op in BoringSSL.)
## Significant API additions
In some places, BoringSSL has added significant APIs. Use of these APIs goes beyound “porting” and means giving up on OpenSSL compatibility.
One example of this has already been mentioned: the [CBS and CBB](https://commondatastorage.googleapis.com/chromium-boringssl-docs/bytestring.h.html) functions should be used whenever parsing or serialising data.
### CRYPTO\_BUFFER
With the standard OpenSSL APIs, when making many TLS connections, the certificate data for each connection is retained in memory in an expensive `X509` structure. Additionally, common certificates often appear in the chains for multiple connections and are needlessly duplicated in memory.
A [`CRYPTO_BUFFER`](https://commondatastorage.googleapis.com/chromium-boringssl-docs/pool.h.html) is just an opaque byte string. A `CRYPTO_BUFFER_POOL` is an intern table for these buffers, i.e. it ensures that only a single copy of any given byte string is kept for each pool.
The function `TLS_with_buffers_method` returns an `SSL_METHOD` that avoids creating `X509` objects for certificates. Additionally, `SSL_CTX_set0_buffer_pool` can be used to install a pool on an `SSL_CTX` so that certificates can be deduplicated across connections and across `SSL_CTX`s.
When using these functions, the application also needs to ensure that it doesn't call other functions that deal with `X509` or `X509_NAME` objects. For example, `SSL_get_peer_certificate` or `SSL_get_peer_cert_chain`. Doing so will trigger an assert in debug mode and will result in NULLs in release mode. Instead, call the buffer-based alternatives such as `SSL_get0_peer_certificates`. (See [ssl.h](https://commondatastorage.googleapis.com/chromium-boringssl-docs/ssl.h.html) for functions taking or returning `CRYPTO_BUFFER`.) The buffer-based alternative functions will work even when not using `TLS_with_buffers_method`, thus application code can transition gradually.
In order to use buffers, the application code also needs to implement its own certificate verification using `SSL_[CTX_]set_custom_verify`. Otherwise all connections will fail with a verification error. Auto-chaining is also disabled when using buffers.
Once those changes have been completed, the whole of the OpenSSL X.509 and ASN.1 code should be eliminated by the linker if BoringSSL is linked statically.
### Asynchronous and opaque private keys
OpenSSL offers the ENGINE API for implementing opaque private keys (i.e. private keys where software only has oracle access because the secrets are held in special hardware or on another machine). While the ENGINE API has been mostly removed from BoringSSL, it is still possible to support opaque keys in this way. However, when using such keys with TLS and BoringSSL, you should strongly prefer using `SSL_PRIVATE_KEY_METHOD` via `SSL[_CTX]_set_private_key_method`. This allows a handshake to be suspended while the private operation is in progress. It also supports more forms of opaque key as it exposes higher-level information about the operation to be performed.

# BoringSSL
BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general
use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing
so is likely to be frustrating because there are no guarantees of API or ABI
stability.
Programs ship their own copies of BoringSSL when they use it and we update
everything as needed when deciding to make API changes. This allows us to
mostly avoid compromises in the name of compatibility. It works for us, but it
may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and,
over time, built up a large number of patches that were maintained while
tracking upstream OpenSSL. As Google's product portfolio became more complex,
more copies of OpenSSL sprung up and the effort involved in maintaining all
these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's
not part of the NDK) and a number of other apps/programs.

# Using BoringSSL in a Sandbox
Sandboxes are a valuable tool for securing applications, so BoringSSL aims to
support them. However, it is difficult to make concrete API guarantees with
sandboxes. Sandboxes remove low-level OS resources and system calls, which
breaks platform abstractions. A syscall-filtering sandbox may, for instance, be
sensitive to otherwise non-breaking changes to use newer syscalls
in either BoringSSL or the C library.
Some functions in BoringSSL, such as `BIO_new_file`, inherently need OS
resources like the filesystem. We assume that sandboxed consumers either avoid
those functions or make necessary resources available. Other functions like
`RSA_sign` are purely computational, but still have some baseline OS
dependencies.
Sandboxes which drop privileges partway through a process's lifetime are
additionally sensitive to OS resources retained across the transitions. For
instance, if a library function internally opened and retained a handle to the
user's home directory, and then the application called `chroot`, that handle
would be a sandbox escape.
This document attempts to describe these baseline OS dependencies and long-lived
internal resources. These dependencies may change over time, but we aim to
[work with sandboxed consumers](/BREAKING-CHANGES.md) when they do. However,
each sandbox imposes different constraints, so, above all, sandboxed consumers
must have ample test coverage to detect issues as they arise.
## Baseline dependencies
Callers must assume that any BoringSSL function may perform one of the following
operations:
### Memory allocation
Any BoringSSL function may allocate memory via `malloc` and related functions.
### Thread synchronization
Any BoringSSL function may call into the platform's thread synchronization
primitives, including read/write locks and the equivalent of `pthread_once`.
These must succeed, or BoringSSL will abort the process. Callers, however, can
assume that BoringSSL functions will not spawn internal threads, unless
otherwise documented.
Syscall-filtering sandboxes should note that BoringSSL uses `pthread_rwlock_t`
on POSIX systems, which is less common and may not be part of other libraries'
syscall surface. Additionally, thread synchronization primitives usually have an
atomics-based fast path. If a sandbox blocks a necessary pthreads syscall, it
may not show up in testing without lock contention.
### Standard error
Any BoringSSL function may write to `stderr` or file descriptor
`STDERR_FILENO` (2), either via `FILE` APIs or low-level functions like `write`.
Writes to `stderr` may fail, but there must some file at `STDERR_FILENO` which
will tolerate error messages from BoringSSL. (The file descriptor must be
allocated so calls to `open` do not accidentally open something else there.)
Note some C standard library implementations also log to `stderr`, so callers
should ensure this regardless.
### Entropy
Any BoringSSL function may draw entropy from the OS. On Windows, this uses
`RtlGenRandom` and, on POSIX systems, this uses `getrandom`, `getentropy`, or a
`read` from a file descriptor to `/dev/urandom`. These operations must succeed
or BoringSSL will abort the process. BoringSSL only probes for `getrandom`
support once and assumes support is consistent for the lifetime of the address
space (and any copies made via `fork`). If a syscall-filtering sandbox is
enabled partway through this lifetime and changes whether `getrandom` works,
BoringSSL may abort the process. Sandboxes are recommended to allow
`getrandom`.
Note even deterministic algorithms may require OS entropy. For example,
RSASSA-PKCS1-v1_5 is deterministic, but BoringSSL draws entropy to implement
RSA blinding.
Entropy gathering additionally has some initialization dependencies described in
the following section.
## Initialization
BoringSSL has some uncommon OS dependencies which are only used once to
initialize some state. Sandboxes which drop privileges after some setup work may
use `CRYPTO_pre_sandbox_init` to initialize this state ahead of time. Otherwise,
callers must assume any BoringSSL function may depend on these resources, in
addition to the operations above.
### CPU capabilities
On Linux ARM platforms, BoringSSL depends on OS APIs to query CPU capabilities.
32-bit and 64-bit ARM both depend on the `getauxval` function. 32-bit ARM, to
work around bugs in older Android devices, may additionally read `/proc/cpuinfo`
and `/proc/self/auxv`.
If querying CPU capabilities fails, BoringSSL will still function, but may not
perform as well.
### Entropy
On Linux systems without a working `getrandom`, drawing entropy from the OS
additionally requires opening `/dev/urandom`. If this fails, BoringSSL will
abort the process. BoringSSL retains the resulting file descriptor, even across
privilege transitions.
### Fork protection
On Linux, BoringSSL allocates a page and calls `madvise` with `MADV_WIPEONFORK`
to protect single-use state from `fork`. This operation must not crash, but if
it fails, BoringSSL will use alternate fork-safety strategies, potentially at a
performance cost. If it succeeds, BoringSSL assumes `MADV_WIPEONFORK` is
functional and relies on it for fork-safety. Sandboxes must not report success
if they ignore the `MADV_WIPEONFORK` flag. As of writing, QEMU will ignore
`madvise` calls and report success, so BoringSSL detects this by calling
`madvise` with -1. Sandboxes must cleanly report an error instead of crashing.
Once initialized, this mechanism does not require system calls in the steady
state, though note the configured page will be inherited across privilege
transitions.
## C and C++ standard library
BoringSSL depends on the C and C++ standard libraries which, themselves, do not
make any guarantees about sandboxes. If it produces the correct answer and has
no observable invalid side effects, it is possible, though unreasonable, for
`memcmp` to create and close a socket.
BoringSSL assumes that functions in the C and C++ library only have the platform
dependencies which would be "reasonable". For instance, a function in BoringSSL
which aims not to open files will still freely call any libc memory and
string functions.
Note some C functions, such as `strerror`, may read files relating to the user's
locale. BoringSSL may trigger these paths and assumes the sandbox environment
will tolerate this. BoringSSL additionally cannot make guarantees about which
system calls are used by standard library's syscall wrappers. In some cases, the
compiler may add dependencies. (Some C++ language features emit locking code.)
Syscall-filtering sandboxes may need updates as these dependencies change.

# BoringSSL Style Guide
BoringSSL usually follows the
[Google C++ style guide](https://google.github.io/styleguide/cppguide.html),
The rest of this document describes differences and clarifications on
top of the base guide.
## Legacy code
As a derivative of OpenSSL, BoringSSL contains a lot of legacy code that
does not follow this style guide. Particularly where public API is
concerned, balance consistency within a module with the benefits of a
given rule. Module-wide deviations on naming should be respected while
integer and return value conventions take precedence over consistency.
Modules from OpenSSL's legacy ASN.1 and X.509 stack are retained for
compatibility and left largely unmodified. To ease importing patches from
upstream, they match OpenSSL's new indentation style. For Emacs,
`doc/openssl-c-indent.el` from OpenSSL may be helpful in this.
## Language
The majority of the project is in C, so C++-specific rules in the
Google style guide do not apply. Support for C99 features depends on
our target platforms. Typically, Chromium's target MSVC is the most
restrictive.
Variable declarations in the middle of a function or inside a `for` loop are
allowed and preferred where possible. Note that the common `goto err` cleanup
pattern requires lifting some variable declarations.
Comments should be `// C99-style` for consistency with C++.
When declaring pointer types, `*` should be placed next to the variable name,
not the type. So
uint8_t *ptr;
not
uint8_t* ptr;
Rather than `malloc()` and `free()`, use the wrappers `OPENSSL_malloc()`
and `OPENSSL_free()`. Use the standard C `assert()` function freely.
Use the following wrappers, found in `crypto/internal.h` instead of the
corresponding C standard library functions. They behave the same but avoid
confusing undefined behavior.
* `OPENSSL_memchr`
* `OPENSSL_memcmp`
* `OPENSSL_memcpy`
* `OPENSSL_memmove`
* `OPENSSL_memset`
For new constants, prefer enums when the values are sequential and typed
constants for flags. If adding values to an existing set of `#define`s,
continue with `#define`.
## libssl
libssl was originally written in C but is being incrementally rewritten in
C++11. As of writing, much of the style matches our C conventions rather than
Google C++. Additionally, libssl on Linux currently may not depend on the C++
runtime. See the C++ utilities in `ssl/internal.h` for replacements for
problematic C++ constructs. The `util/check_imported_libraries.go` script may be
used with a shared library build to check if a new construct is okay.
If unsure, match surrounding code. Discrepancies between it and Google C++ style
will be fixed over time.
## Formatting
Single-statement blocks are not allowed. All conditions and loops must
use braces:
if (foo) {
do_something();
}
not
if (foo)
do_something();
## Integers
Prefer using explicitly-sized integers where appropriate rather than
generic C ones. For instance, to represent a byte, use `uint8_t`, not
`unsigned char`. Likewise, represent a two-byte field as `uint16_t`, not
`unsigned short`.
Sizes are represented as `size_t`.
Within a struct that is retained across the lifetime of an SSL
connection, if bounds of a size are known and it's easy, use a smaller
integer type like `uint8_t`. This is a "free" connection footprint
optimization for servers. Don't make code significantly more complex for
it, and do still check the bounds when passing in and out of the
struct. This narrowing should not propagate to local variables and
function parameters.
When doing arithmetic, account for overflow conditions.
Except with platform APIs, do not use `ssize_t`. MSVC lacks it, and
prefer out-of-band error signaling for `size_t` (see Return values).
## Naming
Follow Google naming conventions in C++ files. In C files, use the
following naming conventions for consistency with existing OpenSSL and C
styles:
Define structs with typedef named `TYPE_NAME`. The corresponding struct
should be named `struct type_name_st`.
Name public functions as `MODULE_function_name`, unless the module
already uses a different naming scheme for legacy reasons. The module
name should be a type name if the function is a method of a particular
type.
Some types are allocated within the library while others are initialized
into a struct allocated by the caller, often on the stack. Name these
functions `TYPE_NAME_new`/`TYPE_NAME_free` and
`TYPE_NAME_init`/`TYPE_NAME_cleanup`, respectively. All `TYPE_NAME_free`
functions must do nothing on `NULL` input.
If a variable is the length of a pointer value, it has the suffix
`_len`. An output parameter is named `out` or has an `out_` prefix. For
instance, For instance:
uint8_t *out,
size_t *out_len,
const uint8_t *in,
size_t in_len,
Name public headers like `include/openssl/evp.h` with header guards like
`OPENSSL_HEADER_EVP_H`. Name internal headers like
`crypto/ec/internal.h` with header guards like
`OPENSSL_HEADER_EC_INTERNAL_H`.
Name enums like `enum unix_hacker_t`. For instance:
enum should_free_handshake_buffer_t {
free_handshake_buffer,
dont_free_handshake_buffer,
};
## Return values
As even `malloc` may fail in BoringSSL, the vast majority of functions
will have a failure case. Functions should return `int` with one on
success and zero on error. Do not overload the return value to both
signal success/failure and output an integer. For example:
OPENSSL_EXPORT int CBS_get_u16(CBS *cbs, uint16_t *out);
If a function needs more than a true/false result code, define an enum
rather than arbitrarily assigning meaning to int values.
If a function outputs a pointer to an object on success and there are no
other outputs, return the pointer directly and `NULL` on error.
## Parameters
Where not constrained by legacy code, parameter order should be:
1. context parameters
2. output parameters
3. input parameters
For example,
/* CBB_add_asn sets |*out_contents| to a |CBB| into which the contents of an
* ASN.1 object can be written. The |tag| argument will be used as the tag for
* the object. It returns one on success or zero on error. */
OPENSSL_EXPORT int CBB_add_asn1(CBB *cbb, CBB *out_contents, unsigned tag);
## Documentation
All public symbols must have a documentation comment in their header
file. The style is based on that of Go. The first sentence begins with
the symbol name, optionally prefixed with "A" or "An". Apart from the
initial mention of symbol, references to other symbols or parameter
names should be surrounded by |pipes|.
Documentation should be concise but completely describe the exposed
behavior of the function. Pay special note to success/failure behaviors
and caller obligations on object lifetimes. If this sacrifices
conciseness, consider simplifying the function's behavior.
// EVP_DigestVerifyUpdate appends |len| bytes from |data| to the data which
// will be verified by |EVP_DigestVerifyFinal|. It returns one on success and
// zero otherwise.
OPENSSL_EXPORT int EVP_DigestVerifyUpdate(EVP_MD_CTX *ctx, const void *data,
size_t len);
Explicitly mention any surprising edge cases or deviations from common
return value patterns in legacy functions.
// RSA_private_encrypt encrypts |flen| bytes from |from| with the private key in
// |rsa| and writes the encrypted data to |to|. The |to| buffer must have at
// least |RSA_size| bytes of space. It returns the number of bytes written, or
// -1 on error. The |padding| argument must be one of the |RSA_*_PADDING|
// values. If in doubt, |RSA_PKCS1_PADDING| is the most common.
//
// WARNING: this function is dangerous because it breaks the usual return value
// convention. Use |RSA_sign_raw| instead.
OPENSSL_EXPORT int RSA_private_encrypt(int flen, const uint8_t *from,
uint8_t *to, RSA *rsa, int padding);
Document private functions in their `internal.h` header or, if static,
where defined.
## Build logic
BoringSSL is used by many projects with many different build tools.
Reimplementing and maintaining build logic in each downstream build is
cumbersome, so build logic should be avoided where possible. Platform-specific
files should be excluded by wrapping the contents in `#ifdef`s, rather than
computing platform-specific file lists. Generated source files such as perlasm
and `err_data.c` may be used in the standalone CMake build but, for downstream
builds, they should be pre-generated in `generate_build_files.py`.

## _aes_encrypt_core_2x
##
## AES-encrypt %xmm0 and %xmm6 in parallel.
##
## Inputs:
## %xmm0 and %xmm6 = input
## %xmm9 and %xmm10 as in _vpaes_preheat
## (%rdx) = scheduled keys
##
## Output in %xmm0 and %xmm6
## Clobbers %xmm1-%xmm5, %xmm7, %xmm8, %xmm11-%xmm13, %r9, %r10, %r11, %rax
## Preserves %xmm14 and %xmm15
##
## This function stitches two parallel instances of _vpaes_encrypt_core. x86_64
## provides 16 XMM registers. _vpaes_encrypt_core computes over six registers
## (%xmm0-%xmm5) and additionally uses seven registers with preloaded constants
## from _vpaes_preheat (%xmm9-%xmm15). This does not quite fit two instances,
## so we spill some of %xmm9 through %xmm15 back to memory. We keep %xmm9 and
## %xmm10 in registers as these values are used several times in a row. The
## remainder are read once per round and are spilled to memory. This leaves two
## registers preserved for the caller.
##
## Thus, of the two _vpaes_encrypt_core instances, the first uses (%xmm0-%xmm5)
## as before. The second uses %xmm6-%xmm8,%xmm11-%xmm13. (Add 6 to %xmm2 and
## below. Add 8 to %xmm3 and up.) Instructions in the second instance are
## indented by one space.

# CRYPTOGAMS licenses depending on where you obtain it. For further
# details see http://www.openssl.org/~appro/cryptogams/.
# ====================================================================
# January 2007.
# Montgomery multiplication for ARMv4.
#
# Performance improvement naturally varies among CPU implementations
# and compilers. The code was observed to provide +65-35% improvement
# [depending on key length, less for longer keys] on ARM920T, and
# +115-80% on Intel IXP425. This is compared to pre-bn_mul_mont code
# base and compiler generated code with in-lined umull and even umlal
# instructions. The latter means that this code didn't really have an
# "advantage" of utilizing some "secret" instruction.
#
# The code is interoperable with Thumb ISA and is rather compact, less
# than 1/2KB. Windows CE port would be trivial, as it's exclusively
# about decorations, ABI and instruction syntax are identical.
# November 2013
#
# Add NEON code path, which handles lengths divisible by 8. RSA/DSA
# performance improvement on Cortex-A8 is ~45-100% depending on key
# length, more for longer keys. On Cortex-A15 the span is ~10-105%.
# On Snapdragon S4 improvement was measured to vary from ~70% to
# incredible ~380%, yes, 4.8x faster, for RSA4096 sign. But this is
# rather because original integer-only code seems to perform
# suboptimally on S4. Situation on Cortex-A9 is unfortunately
# different. It's being looked into, but the trouble is that
# performance for vectors longer than 256 bits is actually couple
# of percent worse than for integer-only code. The code is chosen
# for execution on all NEON-capable processors, because gain on
# others outweighs the marginal loss on Cortex-A9.
