We read it later in grow_init_buf(). If CCS is the first thing received in a flight, then it will use the init_msg from the last flight we received. If the init_buf has been grown in the meantime then it will point to some arbitrary other memory location. This is likely to result in grow_init_buf() attempting to grow to some excessively large amount which is likely to fail. In practice this should never happen because the only time we receive a CCS as the first thing in a flight is in an abbreviated handshake. None of the preceding messages from the server flight would be large enough to trigger this. Reviewed-by:

Since the local symbol table is looked up before the global symbol table, 'arch' assigned in the local symbol table of the DCL where MMS is called would be seen before the 'arch' defined in descrip.mms. Assigning it to the local symbol table in descrip.mms removes that issue. Reviewed-by:

This should demonstrate that the atexit() handling is working properly (or at least not crashing) on process exit. Reviewed-by:
-
Matt Caswell authored
Because we use atexit() to cleanup after ourselves, this will cause a problem if we have been dynamically loaded and then unloaded again: the atexit() handler may no longer be there. Most modern atexit() implementations can handle this, however there are still difficulties if libssl gets unloaded before libcrypto, because of the atexit() callback that libcrypto makes to libssl. The most robust solution seems to be to ensure that libcrypto and libssl never unload. This is done by simply deliberately leaking a dlopen() reference to them. Reviewed-by:

TLS1.0 and TLS1.1 say you SHOULD ignore unrecognised record types, but TLS 1.2 says you MUST send an unexpected message alert. We swap to the TLS 1.2 behaviour for all protocol versions to prevent issues where no progress is being made and the peer continually sends unrecognised record types, using up resources processing them.

This test checks that read_ahead works correctly when dealing with large records. Reviewed-by:
-
Matt Caswell authored
The function ssl3_read_n() takes a parameter |clearold| which, if set, causes any old data in the read buffer to be forgotten, and any unread data to be moved to the start of the buffer. This is supposed to happen when we first read the record header. However, the data move was only taking place if there was not already sufficient data in the buffer to satisfy the request. If read_ahead is set then the record header could be in the buffer already from when we read the preceding record. So with read_ahead we can get into a situation where even though |clearold| is set, the data does not get moved to the start of the read buffer when we read the record header. This means there is insufficient room in the read buffer to consume the rest of the record body, resulting in an internal error. This commit moves the |clearold| processing to earlier in ssl3_read_n() to ensure that it always takes place. Reviewed-by:

Replace the various length checks in the extension code with a macro to simplify the logic. Reviewed-by: -
Matt Caswell authored
The previous commit inspired a review of all the length checks for the extension adding code. This adds more robust checks and adds checks where some were missing previously. The real solution for this is to use WPACKET which is currently in master - but that cannot be applied to release branches. Reviewed-by: -
Matt Caswell authored
The status request extension did not correctly check its length, meaning that writing the extension could go 2 bytes beyond the buffer size. In practice this makes little difference because, due to logic in buffer.c the buffer is actually over allocated by approximately 5k! Issue reported by Guido Vranken. Reviewed-by: -

A BIO_read() 0 return indicates that a failure occurred that may be retryable. An SSL_read() 0 return indicates a non-retryable failure. Check that if BIO_read() returns 0, SSL_read() returns <0. Same for SSL_write(). The asyncio test filter BIO already returns 0 on a retryable failure so we build on that. Reviewed-by:

Matt Caswell authored
A zero return from BIO_read()/BIO_write() could mean that an IO operation is retryable. A zero return from SSL_read()/SSL_write() means that the connection has been closed down (either cleanly or not). Therefore we should not propagate a zero return value from BIO_read()/BIO_write() back up the stack to SSL_read()/SSL_write(). This could result in a retryable failure being treated as fatal.

The current version of the VMS compiler provides C99 features, strictly language wise. Unfortunately, even the most recent standard library isn't fully updated for that standard, so we need to use an earlier standard that the compiler supports. Most importantly, this affects the __STDC_VERSION__ value, which the compiler unfortunately currently defaults to 199901L. With this change we won't have to give VMS special treatment when looking for features based on that macro. Reviewed-by:
