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.

Including e_os.h with a path from a header file doesn't work well on certain exotic platform. It simply fails to build. Since we don't seem to be able to stop ourselves, the better move is to move e_os.h to an include directory that's part of the inclusion path given to the compiler.

2019-12-14Deprecate most of debug-memoryRich Salz
Fixes #8322 The leak-checking (and backtrace option, on some platforms) provided by crypto-mdebug and crypto-mdebug-backtrace have been mostly neutered; only the "make malloc fail" capability remains. OpenSSL recommends using the compiler's leak-detection instead. The OPENSSL_DEBUG_MEMORY environment variable is no longer used. CRYPTO_mem_ctrl(), CRYPTO_set_mem_debug(), CRYPTO_mem_leaks(), CRYPTO_mem_leaks_fp() and CRYPTO_mem_leaks_cb() return a failure code. CRYPTO_mem_debug_{malloc,realloc,free}() have been removed.

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.

2018-01-31Revert the crypto "global lock" implementationBenjamin Kaduk
Conceptually, this is a squashed version of: Revert "Address feedback" This reverts commit 75551e07bd2339dfea06ef1d31d69929e13a4495. and Revert "Add CRYPTO_thread_glock_new" This reverts commit ed6b2c7938ec6f07b15745d4183afc276e74c6dd. But there were some intervening commits that made neither revert apply cleanly, so instead do it all as one shot. The crypto global locks were an attempt to cope with the awkward POSIX semantics for pthread_atfork(); its documentation (the "RATIONALE" section) indicates that the expected usage is to have the prefork handler lock all "global" locks, and the parent and child handlers release those locks, to ensure that forking happens with a consistent (lock) state. However, the set of functions available in the child process is limited to async-signal-safe functions, and pthread_mutex_unlock() is not on the list of async-signal-safe functions! The only synchronization primitives that are async-signal-safe are the semaphore primitives, which are not really appropriate for general-purpose usage. However, the state consistency problem that the global locks were attempting to solve is not actually a serious problem, particularly for OpenSSL. That is, we can consider four cases of forking application that might use OpenSSL: (1) Single-threaded, does not call into OpenSSL in the child (e.g., the child calls exec() immediately) For this class of process, no locking is needed at all, since there is only ever a single thread of execution and the only reentrancy is due to signal handlers (which are themselves limited to async-signal-safe operation and should not be doing much work at all). (2) Single-threaded, calls into OpenSSL after fork() The application must ensure that it does not fork() with an unexpected lock held (that is, one that would get unlocked in the parent but accidentally remain locked in the child and cause deadlock). Since OpenSSL does not expose any of its internal locks to the application and the application is single-threaded, the OpenSSL internal locks will be unlocked for the fork(), and the state will be consistent. (OpenSSL will need to reseed its PRNG in the child, but that is an orthogonal issue.) If the application makes use of locks from libcrypto, proper handling for those locks is the responsibility of the application, as for any other locking primitive that is available for application programming. (3) Multi-threaded, does not call into OpenSSL after fork() As for (1), the OpenSSL state is only relevant in the parent, so no particular fork()-related handling is needed. The internal locks are relevant, but there is no interaction with the child to consider. (4) Multi-threaded, calls into OpenSSL after fork() This is the case where the pthread_atfork() hooks to ensure that all global locks are in a known state across fork() would come into play, per the above discussion. However, these "calls into OpenSSL after fork()" are still subject to the restriction to async-signal-safe functions. Since OpenSSL uses all sorts of locking and libc functions that are not on the list of safe functions (e.g., malloc()), this case is not currently usable and is unlikely to ever be usable, independently of the locking situation. So, there is no need to go through contortions to attempt to support this case in the one small area of locking interaction with fork(). In light of the above analysis (thanks @davidben and @achernya), go back to the simpler implementation that does not need to distinguish "library-global" locks or to have complicated atfork handling for locks.

2016-02-26RT4335: Fix UEFI build of OBJ_NAME_new_index()David Woodhouse
We are using strcmp() as the cmp_func, where in the EDK2 environment strcmp actually ends up being the external AsciiStrCmp() function — an EFI library function defined with the Microsoft ABI. This means that we can't just assign function pointers to it, since in GCC-hosted builds the ABI of any function *not* explicitly marked EFIAPI is the native SysV ABI. Arguably this stupidity ought to be resolved on the UEFI side, but in the general case that would mean that we need to provide ABI-compatible wrappers for *all* the "standard" functions, just in case they're used like this. And in fact we already have a workaround here for DEC C. So instead of playing games with casting function pointers, it's nicer just to use a simple function to wrap the strcmp() call. That cleans up the DEC C workaround, *and* it works around the UEFI bogosity at the same time. Signed-off-by: Rich Salz <rsalz@openssl.org> Reviewed-by: Kurt Roeckx <kurt@openssl.org>
