* Revert bio_prev removaltb2022-12-021-1/+10
| | | | | | | | | As schwarze points out, you can pop any BIO in a chain, not just the first one (bonus points for a great name for this API). The internal doubly linked was used to fix up the BIO chain bio was part of when you BIO_pop() a bio that wasn't in the first position, which is explicitly allowed in our documentation and implied by OpenSSL's.
* Mostly align BIO_read()/BIO_write() return values with OpenSSL 3.x.jsing2022-11-301-7/+21
| | | | | | | | | | For various historical reasons, there are a number of cases where our BIO_read() and BIO_write() return slightly different values to what OpenSSL 3.x does (of course OpenSSL 1.0 differs from OpenSSL 1.1 which differs from OpenSSL 3.x). Mostly align these - some further work will be needed. Issue raised by tb@ who also wrote some test code.
* Retire prev_biotb2022-11-281-10/+1
| | | | | | | | | | | | | While BIO chains are doubly linked lists, nothing has ever made use of this fact internally. Even libssl has failed to maintain prev_bio properly in two places for a long time. When BIO was made opaque, the opportunity to fix that was missed. Instead, BIO_set_next() now allows breaking the lists from outside the library, which freerdp has long done. Problem found by schwarze while trying to document BIO_set_next(). schwarze likes the idea ok jsing
* Initialize readbytes in BIO_gets()tb2022-08-151-2/+2
| | | | | | | | If the bgets() callback returns <= 0, we currently rely on the user provided callback to set readbytes, which isn't ideal. This also matches what's done in BIO_read() and BIO_write(). ok jsing
* Implement new-style OpenSSL BIO callbackstb2022-01-141-85/+203
| | | | | | | | | | 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

* 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@

* 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@
