| * | | | | | | | sfxge(4): add API to allocate and free RSS contextsAndrew Rybchenko2018-11-235-0/+138

All these really report is whether an exclusive RSS context was successfully acquired at efx_rx_init(). efx_rx_scale_support_get() sounds like it reports whether the device supports RSS, and whether exclusive or shared contexts are supported, but it doesn't do that. Renaming it to efx_rx_scale_default_support_get() helps to reflect that it reports what RSS support the client gets without trying to allocate RSS contexts itself. Also rename efx_rx_scale_support_t to efx_rx_scale_context_type_t, to make the enum more suitable for specifying the type of an RSS context to be allocated.

So filters for encapsulated packets need to be inserted for each class of encapsulated packet. For simplicity, catch-all filters are always inserted. These may match more packets than the OS has asked for, but trying to insert more precise filters increases complexity for little gain.

With the fix exit codepath was waking up the parent before the child fully transitioned to a zombie. Woken up parent would waitpid, which could find a not-yet-zombie child and fail to reap it due to the WNOHANG flag. While removing the flag fixes the problem, it is not an option due to older releases which would still suffer from the kernel change. Revert the fix until a solution can be worked out. Note that while use-after-free which gets back due to the revert is a real bug, it's side-effects are limited due to the fact that struct proc memory is never released by UMA.

Then it is blindly used to wait until P_PPWAIT is cleared. However, if the child is autoreaped it could have exited and get freed before the parent started waiting. Use the existing hold mechanism to mitigate the problem. Most common case of doing exec remains unchanged. The corner case of doing exit performs wake up before waiting for holds to clear.

For EVFILT_TIMER knotes, there is no knlist lock, so the knote activation could occur during the kn_status update and result in KN_QUEUED being lost, in which case we'd enqueue an already-enqueued knote, corrupting the queue. Fix the problem by setting or clearing KN_DISABLED before dropping the kqueue lock to call into the filter. KN_DISABLED is used only by the core kevent code, so there is no side effect from setting it earlier.
