We're still facing the situation where it's impossible to update an FD for a foreign group. That's of particular concern when disabling/enabling listeners (e.g. pause/resume on signals) since we don't decide which thread gets the signal and it needs to process all listeners at once. Fortunately, not that much is unprotected in FDs. This patch adds a test for tgid's equality in updt_fd_polling() so that if a change is applied for a foreing group, then it's detected and taken care of separately. The method consists in forcing the update on all bound threads in this group, adding it to the group's update_list, and sending a wake-up as would be done for a remote thread in the local group, except that this is done by grabbing a reference to the FD's tgid. Thanks to this, SIGTTOU/SIGTTIN now work for nbtgroups > 1 (after that was temporarily broken by "MEDIUM: fd/poller: make the update-list per-group"). |
