commit 7eea59b754f37d04a34589c316dcf30bcd8e2b88 Author: Matthew Dillon <dil...@apollo.backplane.com> Date: Thu Jun 4 16:33:04 2020 -0700
kernel - Refactor kern_kevent(), fix timeout overflow (ppoll() bug) * Fix a bug where large timeouts or very small timeouts could overflow the ustimeout variable. Change the internal timeout cap to ensure that no overflow occurs. * Fix another bug where the internal timeout cap could cause ppoll() to return early. Internal tsleep (etc) timeouts need to be ignored because the external timeout might be larger and will handle the error return for us when it is checked. * Refactor kern_kevent() to be somewhat more efficient.
