LGTM. 👍

Mixed approach is used in this file -- some function don't raise an exception, but return an error code (negative, not -1) which then will be converted to exception in handle_channel_error(). Changes in this PR look good, but please check all other returns returning NULL or -1. There may be other bugs in this file.

Sorry, @sobolevn, I could not cleanly backport this to 3.14 due to a conflict.
Please backport using cherry_picker on command line.
