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.

2017-10-30Prevent NULL dereference in async clear-fd codeBenjamin Kaduk
If the list of fds contains only (one or more) entries marked as deleted prior to the entry currently being deleted, and the entry currently being deleted was only just added, the 'prev' pointer would never be updated from its initial NULL value, and we would dereference NULL while trying to remove the entry from the linked list.

2017-02-13Remove fd from the list when the engine clears the wait context before pauseAndrea Grandi
This fixes the num of fds added/removed returned by ASYNC_WAIT_CTX_get_changed_fds Previously, the numbers were not consistent with the fds actually written in the buffers since the fds that have been both added and removed are explicitly ignored in the loop.

2016-02-29Refactor the async wait fd logicMatt Caswell
Implementation experience has shown that the original plan for async wait fds was too simplistic. Originally the async logic created a pipe internally and user/engine code could then get access to it via API calls. It is more flexible if the engine is able to create its own fd and provide it to the async code. Another issue is that there can be a lot of churn in the fd value within the context of (say) a single SSL connection leading to continually adding and removing fds from (say) epoll. It is better if we can provide some stability of the fd value across a whole SSL connection. This is problematic because an engine has no concept of an SSL connection. This commit refactors things to introduce an ASYNC_WAIT_CTX which acts as a proxy for an SSL connection down at the engine layer. Reviewed-by: Richard Levitte <levitte@openssl.org>
