Add CRYPTO_free_ex_index (for shared libraries) Unify and complete the documentation for all "ex_data" API's and objects. Replace xxx_get_ex_new_index functions with a macro. Added an exdata test. Renamed the ex_data internal datatypes. Reviewed-by: Matt Caswell <matt@openssl.org>

2015-10-05Explicitly cast INVALID_SOCKET to (int) to address warnings on Windows.Andy Polyakov
Even though SOCKET is effectively declared as (void *) on Windows, it's not actually a pointer, but an index within per-process table of kernel objects. The table size is actually limited and its upper limit is far below upper limit for signed 32-bit integer. This is what makes cast in question possible.

2015-09-29Fix no-stdio buildDavid Woodhouse
Much related/similar work also done by Ivan Nestlerode <ivan.nestlerode@sonos.com> +Replace FILE BIO's with dummy ops that fail. +Include <stdio.h> for sscanf() even with no-stdio (since the declaration is there). We rely on sscanf() to parse the OPENSSL_ia32cap environment variable, since it can be larger than a 'long'. And we don't rely on the availability of strtoull(). +Remove OPENSSL_stderr(); not used. +Make OPENSSL_showfatal() do nothing (currently without stdio there's nothing we can do). +Remove file-based functionality from ssl/. The function prototypes were already gone, but not the functions themselves. +Remove unviable conf functionality via SYS_UEFI +Add fallback definition of BUFSIZ. +Remove functions taking FILE * from header files. +Add missing DECLARE_PEM_write_fp_const +Disable X509_LOOKUP_hash_dir(). X509_LOOKUP_file() was already compiled out, so remove its prototype. +Use OPENSSL_showfatal() in CRYPTO_destroy_dynlockid(). +Eliminate SRP_VBASE_init() and supporting functions. Users will need to build the verifier manually instead. +Eliminate compiler warning for unused do_pk8pkey_fp(). +Disable TEST_ENG_OPENSSL_PKEY. +Disable GOST engine as is uses [f]printf all over the place. +Eliminate compiler warning for unused send_fp_chars().

2015-09-21RT3479: Add UTF8 support to BIO_read_filename()David Woodhouse
If we use BIO_new_file(), on Windows it'll jump through hoops to work around their unusual charset/Unicode handling. it'll convert a UTF-8 filename to UCS-16LE and attempt to use _wfopen(). If you use BIO_read_filename(), it doesn't do this. Shouldn't it be consistent? It would certainly be nice if SSL_use_certificate_chain_file() worked.

2015-06-10Change BIO_number_read and BIO_number_written() to be 64 bitMatt Caswell
The return type of BIO_number_read() and BIO_number_written() as well as the corresponding num_read and num_write members in the BIO structure has been changed from unsigned long to uint64_t. On platforms where an unsigned long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is transferred. With thanks to the Open Crypto Audit Project for reporting this issue.

2015-06-10Fix memory leaks in BIO_dup_chain()Matt Caswell
This fixes a memory leak that can occur whilst duplicating a BIO chain if the call to CRYPTO_dup_ex_data() fails. It also fixes a second memory leak where if a failure occurs after successfully creating the first BIO in the chain, then the beginning of the new chain was not freed.

2015-05-22Fix the update target and remove duplicate file updatesRichard Levitte
We had updates of certain header files in both Makefile.org and the Makefile in the directory the header file lived in. This is error prone and also sometimes generates slightly different results (usually just a comment that differs) depending on which way the update was done. This removes the file update targets from the top level Makefile, adds an update: target in all Makefiles and has it depend on the depend: or local_depend: targets, whichever is appropriate, so we don't get a double run through the whole file tree.

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>

2015-04-30Clarify logic in BIO_*printf functionsMatt Caswell
The static function dynamically allocates an output buffer if the output grows larger than the static buffer that is normally used. The original logic implied that |currlen| could be greater than |maxlen| which is incorrect (and if so would cause a buffer overrun). Also the original logic would call OPENSSL_malloc to create a dynamic buffer equal to the size of the static buffer, and then immediately call OPENSSL_realloc to make it bigger, rather than just creating a buffer than was big enough in the first place.

This engine is for VMS only, and isn't really part of the core OpenSSL but rather a side project of its own that just happens to have tagged along for a long time. The reasons why it has remained within the OpenSSL source are long lost in history, and there not being any real reason for it to remain here, it's time for it to move out. This side project will appear as a project in its own right, the location of which will be announced later on. Reviewed-by: Tim Hudson <tjh@openssl.org>
