* Clean up and simplify memory BIO code.jsing2022-02-181-124/+139
| | | | | | | | This is a first pass that uses sensible and consistent names for variables. Call the BIO 'bio' (instead of 'a', 'b', 'bp', or 'h'), drop a bunch of unnecessary casts, simplify some logic and add additional error checking. With input from and ok tb@
* Implement new-style OpenSSL BIO callbackstb2022-01-1410-130/+251
| | | | | | | | | | This provides support for new-style BIO callbacks in BIO_{read,write,gets,puts}() and a helper function to work out whether it should call the new or the old style callback. It also adds a few typedefs and minor code cleanup as well as the BIO_{get,set}_callback_ex() from jsing, ok tb
* Make structs in bio.h opaquetb2022-01-142-60/+60
| | | | | | | Move BIO, BIO_METHOD and BIO_F_BUFFER_CTX to bio_local.h and provide BIO typedef in ossl_typ.h. ok inoguchi jsing
* Remove BIO_s_file_internaltb2022-01-141-4/+1
| | | | | | | Pointed out by schwarze. How something with this name ever made its way into a public header will remain a mystery. ok inoguchi jsing
* Unifdef LIBRESSL_OPAQUE_* and LIBRESSL_NEXT_APItb2022-01-141-5/+1
| | | | | This marks the start of major surgery in libcrypto. Do not attempt to build the tree for a while (~50 commits).
* Add a new, mostly empty, bio_local.h and include it in the filestb2022-01-0717-16/+114
| | | | | | that will need it in the upcoming bump. discussed with jsing
* Prepare to provide BIO_set_retry_reason()tb2022-01-052-2/+11
| | | | | | Needed by freerdp. ok inoguchi jsing
* Prepare to provide BIO_set_next().tb2022-01-052-2/+11
| | | | | | This will be needed in libssl and freerdp after the next bump. ok inoguchi jsing
* Fix an issue that might possibly turn into a DOS depending onschwarze2021-12-091-3/+3
| | | | | | | | | | how application software uses the API function BIO_indent(3): If the caller asks for some output, but not more than some negative number of bytes, give them zero bytes of output rather than drowning them in nearly INT_MAX bytes. OK tb@
* Hide BIO_s_file_internal() from internal view.tb2021-11-291-2/+4
| | | | ok jsing
* Unifdef LIBRESSL_NEW_API. Now that the library is bumped, this istb2021-11-011-3/+1
| | | | | | no longer needed. ok jsing
* Prepare to provide BIO_get_init()tb2021-10-242-5/+14
| | | | ok beck jsing
* While the traditional OpenSSL return value and behaviour of BIO_dump(3)beck2021-07-111-5/+10
| | | | | | | | | | | is pure comedy gold, and now documented as such, sadly this bit of pure Muppet genius can't really in good consience stay in the tree as is. Change BIO_dump to always return the number of bytes printed on success and to stop printing and return -1 on failure if a writing function fails. ok tb@, jsing@
* Avoid mangled output in BIO_debug_callbacktb2021-03-251-4/+12
| | | | | | | Instead of blindly skipping 14 characters, we can use the return value of snprintf() to determine how much we should skip. From Martin Vahlensieck with minor tweaks by me
* failed to detect asprintf() error by observing return of -1, instead thederaadt2019-06-281-6/+3
| | | | | code was inspecting the pointer (which is, sadly, undefined on error, because the current specification of asprintf is crazy sloppy)
* Add input validation to BIO_read()/BIO_write().jsing2019-04-141-4/+14
| | | | | | | | | Some bread/bwrite functions implement this themselves, while others do not. This makes it consistent across all BIO implementations. Addresses an issue that Guido Vranken found with his fuzzer. ok tb@
* Add const to the argument of the following callback getters:tb2018-06-022-18/+18
| | | | | | | | BIO_meth_get_callback_ctrl, BIO_meth_get_create, BIO_meth_get_ctrl, BIO_meth_get_destroy, BIO_meth_get_gets, BIO_meth_get_puts, BIO_meth_get_read, and BIO_meth_get_write. ok jsing
* Add a const qualifier to the return value of BIO_s_file().tb2018-05-302-5/+5
| | | | | tested in a bulk build by sthen ok bcook, jsing
* const qualifiers for BIO_new_mem_buf(), BIO_new_connect() andtb2018-05-124-11/+11
| | | | | | | | BIO_new_accept(). The one for BIO_new_mem_buf() is a bit ugly since it needs to cast away the newly added const qualifier, as in OpenSSL commit 8ab31975bac. ok jsing
* Add const qualifiers to the return values of BIO_s_mem() andtb2018-05-123-9/+9
| | | | | | BIO_s_datagram(). ok jsing
* const for BIO_{new,set}() and most of the BIO_{f,s}_*() family oftb2018-05-0112-47/+47
| | | | | | functions. ok beck, jsing
* Bring in compatibility for OpenSSL 1.1 style init functions.beck2018-03-171-1/+3
| | | | | | | | | This adds OPENSSL_init_crypto and OPENSSL_init_ssl, as well thread safety modifications for the existing LibreSSL init functions. The initialization routines are called automatically by the normal entry points into the library, as in newer OpenSSL ok jsing@, nits by tb@ and deraadt@

| | | | | | | | | Coverity issue 72741 noticed that ret is being overwritten before use. The actual issue is that the #if/else logic is guarding the wrong lines. Besides impacting ret, this also made the case's break logic wrong because it was in the wrong location. ok bcook@ beck@
