commit f3c74b38 upstream. Switch to using Donald Knuth's binary search algorithm (The Art of Computer Programming, vol. 3, section 6.2.1). This should've been done from the very beginning but the author must've been smoking something very potent at the time. The problem with the current one was that it would return the wrong element index in certain situations: https://lkml.kernel.org/r/CAM_iQpVd02zkVJ846cj-Fg1yUNuz6tY5q1Vpj4LrXmE06dPYYg@mail.gmail.com and the noodling code after the loop was fishy at best. So switch to using Knuth's binary search. The final result is much cleaner and straightforward. Fixes: 011d8261 ("RAS: Add a Corrected Errors Collector") Reported-by:

commit 0ade0b62 upstream. cec_timer_fn() is a timer callback which reads ce_arr.array[] and updates its decay values. However, it runs in interrupt context and the mutex protection the CEC uses for that array, is inadequate. Convert the used timer to a workqueue to keep the tasks the CEC performs preemptible and thus low-prio. [ bp: Rewrite commit message. s/timer/decay/gi to make it agnostic as to what facility is used. ] Fixes: 011d8261 ("RAS: Add a Corrected Errors Collector") Signed-off-by:

commit e3ff9c36 upstream. Jason reported that the coarse ktime based time getters advance only once per second and not once per tick as advertised. The code reads only the monotonic base time, which advances once per second. The nanoseconds are accumulated on every tick in xtime_nsec up to a second and the regular time getters take this nanoseconds offset into account, but the ktime_get_coarse*() implementation fails to do so. Add the accumulated xtime_nsec value to the monotonic base time to get the proper per tick advancing coarse tinme. Fixes: b9ff604c ("timekeeping: Add ktime_get_coarse_with_offset") Reported-by:

commit f01098c7 upstream. Just like the case of commit 8b05a3a7 ("tracing/kprobes: Fix NULL pointer dereference in trace_kprobe_create()"), writing an incorrectly formatted string to uprobe_events can trigger NULL pointer dereference.

commit babd1839 upstream. In commit abb62184 ("usb: ch9: make usb_endpoint_maxp() return only packet size") the API to usb_endpoint_maxp() changed. It used to just return wMaxPacketSize but after that commit it returned wMaxPacketSize with the high bits (the multiplier) masked off. If you wanted to get the multiplier it was now up to your code to call the new usb_endpoint_maxp_mult() which was introduced in commit 541b6fe6 ("usb: add helper to extract bits 12:11 of wMaxPacketSize"). Prior to the API change most host drivers were updated, but no update was made to dwc2. Presumably it was assumed that dwc2 was too simplistic to use the multiplier and thus just didn't support a certain class of USB devices. However, it turns out that dwc2 did use the multiplier and many devices using it were working quite nicely. That means that many USB devices have been broken since the API change. One such device is a Logitech HD Pro Webcam C920. Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it did call usb_maxpacket() which in turn called usb_endpoint_maxp(). Let's update dwc2 to work properly with the new API. Fixes: abb62184 ("usb: ch9: make usb_endpoint_maxp() return only packet size") Cc: stable@vger.kernel.org Acked-by:

[ Upstream commit 883d25e7 ] The fields filter would not work with child fields, as the respective parents would not be included. No parents displayed == no childs displayed. To reproduce, run on s390 (would work on other platforms, too, but would require a different filter name): - Run 'kvm_stat -d' - Press 'f' - Enter 'instruct' Notice that events like instruction_diag_44 or instruction_diag_500 are not displayed - the output remains empty. With this patch, we will filter by matching events and their parents. However, consider the following example where we filter by instruction_diag_44: kvm statistics - summary regex filter: instruction_diag_44 Event Total %Total CurAvg/s exit_instruction 276 100.0 12 instruction_diag_44 256 92.8 11 Total 276 12 Note that the parent ('exit_instruction') displays the total events, but the childs listed do not match its total (256 instead of 276). This is intended (since we're filtering all but one child), but might be confusing on first sight. Signed-off-by:

[ Upstream commit bffed38d ] The memory slot size must be aligned to the host's page size. When testing a guest with a 4k page size on a host with a 64k page size, then 3 guest pages are not host page size aligned. Since we just need a nearly arbitrary number of extra pages to ensure the memslot is not aligned to a 64 host-page boundary for this test, then we can use 16, as that's 64k aligned, but not 64 * 64k aligned.

[ Upstream commit 94d250fa ] Fix a racing condition in ipheth.c that can lead to slow performance. Bug: In ipheth_tx(), netif_wake_queue() may be called on the callback ipheth_sndbulk_callback(), _before_ netif_stop_queue() is called. When this happens, the queue is stopped longer than it needs to be, thus reducing network performance. Fix: Move netif_stop_queue() in front of usb_submit_urb(). Now the order is always correct. In case, usb_submit_urb() fails, the queue is woken up again as callback will not fire. Testing: This racing condition is usually not noticeable, as it has to occur very frequently to slowdown the network. The callback from the USB is usually triggered slow enough, so the situation does not appear. However, on a Ubuntu Linux on VMWare Workstation, running on Windows 10, the we loose the race quite often and the following speedup can be noticed: Without this patch: Download: 4.10 Mbit/s, Upload: 4.01 Mbit/s With this patch: Download: 36.23 Mbit/s, Upload: 17.61 Mbit/s Signed-off-by:

[ Upstream commit 55267c88 ] hist_field_var_ref() is an implementation of hist_field_fn_t(), which can be called with a null tracing_map_elt elt param when assembling a key in event_hist_trigger(). In the case of hist_field_var_ref() this doesn't make sense, because a variable can only be resolved by looking it up using an already assembled key i.e. a variable can't be used to assemble a key since the key is required in order to access the variable. Upper layers should prevent the user from constructing a key using a variable in the first place, but in case one slips through, it shouldn't cause a NULL pointer dereference. Also if one does slip through, we want to know about it, so emit a one-time warning in that case.

[ Upstream commit fe483192 ] When running under a pipe, some timer tests would not report output in real-time because stdout flushes were missing after printf()s that lacked a newline. This adds them to restore real-time status output that humans can enjoy. Signed-off-by:
