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.

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. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)
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.

2016-04-13Remake the way dynamic zlib is loadedRichard Levitte
Instead of absolute hard coding of the libz library name, have it use the macro LIBZ, which is set to defaults we know in case it's undefined. This allows our configuration to set something that's sane on current or older platforms, and allows the user to override it by defining LIBZ themselves. Reviewed-by: Matt Caswell <matt@openssl.org>

Add -DBIO_DEBUG to --strict-warnings. Remove comments about outdated debugging ifdef guards. Remove md_rand ifdef guarding an assert; it doesn't seem used. Remove the conf guards in conf_api since we use OPENSSL_assert, not assert. For pkcs12 stuff put OPENSSL_ in front of the macro name. Merge TLS_DEBUG into SSL_DEBUG. Various things just turned on/off asserts, mainly for checking non-NULL arguments, which is now removed: camellia, bn_ctx, crypto/modes. Remove some old debug code, that basically just printed things to stderr: DEBUG_PRINT_UNKNOWN_CIPHERSUITES, DEBUG_ZLIB, OPENSSL_RI_DEBUG, RL_DEBUG, RSA_DEBUG, SCRYPT_DEBUG.

2015-05-12Make COMP_CTX and COMP_METHOD opaqueRich Salz
Since COMP_METHOD is now defined in comp_lcl.h, it is no longer possible to create new TLS compression methods without using the OpenSSL source. Only ZLIB is supported by default. Also, since the types are opaque, #ifdef guards to use "char *" instead of the real type aren't necessary. The changes are actually minor. Adding missing copyright to some files makes the diff misleadingly big. Reviewed-by: Matt Caswell <matt@openssl.org>
2015-05-04Use safer sizeof variant in mallocRich Salz
For a local variable: TYPE *p; Allocations like this are "risky": p = OPENSSL_malloc(sizeof(TYPE)); if the type of p changes, and the malloc call isn't updated, you could get memory corruption. Instead do this: p = OPENSSL_malloc(sizeof(*p)); Also fixed a few memset() calls that I noticed while doing this. Reviewed-by: Richard Levitte <levitte@openssl.org>
