2024-04-04posix_async: FreeBSD also defines {make|swap|get|set}contextWarner Losh
FreeBSD also defines {make|swap|get|set}context for backward compatibility, despite also exposing POSIX_VERSION 200809L in FreeBSD 15-current. Note: There's no fallback for POSIX_VERSION 200809 without these routines, so maybe that should be a #error?

2022-10-05Stop raising ERR_R_MALLOC_FAILURE in most placesRichard Levitte
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and at least handle the file name and line number they are called from, there's no need to report ERR_R_MALLOC_FAILURE where they are called directly, or when SSLfatal() and RLAYERfatal() is used, the reason `ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`. There were a number of places where `ERR_R_MALLOC_FAILURE` was reported even though it was a function from a different sub-system that was called. Those places are changed to report ERR_R_{lib}_LIB, where {lib} is the name of that sub-system. Some of them are tricky to get right, as we have a lot of functions that belong in the ASN1 sub-system, and all the `sk_` calls or from the CRYPTO sub-system. Some extra adaptation was necessary where there were custom OPENSSL_malloc() wrappers, and some bugs are fixed alongside these changes.

2022-03-01aarch64: Fix async_fibre_swapcontext() on clang BTI buildsTom Cosgrove
Reverting to using swapcontext() when compiling with clang on BTI-enabled builds fixes the BTI setjmp() failure seen when running asynctest. The issue with setjmp/longjmp is a known clang bug: see https://github.com/llvm/llvm-project/issues/48888 Change-Id: I6eeaaa2e15f402789f1b3e742038f84bef846e29 Reviewed-by: Matt Caswell <matt@openssl.org> Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/17698)
2022-01-04Use USE_SWAPCONTEXT on IA64.Sebastian Andrzej Siewior
On IA64 the use of setjmp()/ longjmp() does not properly save the state of the register stack engine (RSE) and requires extra care. The use of it in the async interface led to a failure in the test_async.t test since its introduction in 1.1.0 series. Instead of properly adding the needed assembly bits here use the swapcontext() function which properly saves the whole context.

CreateFiber and ConvertThreadToFiber are not allowed in Windows Store (Universal Windows Platform) apps since they have been replaced by their Ex variants which have a new dwFlags parameter. This flag allows the fiber to do floating-point arithmetic in the fiber on x86, which would silently cause corruption otherwise since the floating-point state is not switched by default.

2020-06-28Make the ASYNC code default libctx awareMatt Caswell
Since the default libctx is now stored in a thread local variable swapping in and out of fibres in the ASYNC code could mean that the "current" default libctx can get confused. Therefore we ensure that everytime we call async_fibre_swapcontext() we always restore the default libctx to whatever it was the last time the fibre ran. Similarly when async_fibre_swapcontext() returns we need to restore the current thread's default libctx.

2019-09-28Reorganize local header filesDr. Matthias St. Pierre
Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly.

2019-09-28Reorganize private crypto header filesDr. Matthias St. Pierre
Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

The output C code was made to use ERR_func_error_string() to see if a string table was already loaded or not. Since this function returns NULL always, this check became useless. Change it to use ERR_reason_error_string() instead, as there's no reason to believe we will get rid of reason strings, ever. To top it off, we rebuild all affected C sources.
