FAILED: patch "[PATCH] powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across" failed to apply to 3.18-stable tree

The patch below does not apply to the 3.18-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b5b4453e7912f056da1ca7572574cada32ecb60c Mon Sep 17 00:00:00 2001 From: Michael Ellerman <mpe(a)ellerman.id.au> Date: Thu, 14 Mar 2019 00:14:38 +1100 Subject: [PATCH] powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across Y2038 Jakub Drnec reported: Setting the realtime clock can sometimes make the monotonic clock go back by over a hundred years. Decreasing the realtime clock across the y2k38 threshold is one reliable way to reproduce. Allegedly this can also happen just by running ntpd, I have not managed to reproduce that other than booting with rtc at >2038 and then running ntp. When this happens, anything with timers (e.g. openjdk) breaks rather badly. And included a test case (slightly edited for brevity): #define _POSIX_C_SOURCE 199309L #include <stdio.h> #include <time.h> #include <stdlib.h> #include <unistd.h> long get_time(void) { struct timespec tp; clock_gettime(CLOCK_MONOTONIC, &tp); return tp.tv_sec + tp.tv_nsec / 1000000000; } int main(void) { long last = get_time(); while(1) { long now = get_time(); if (now < last) { printf("clock went backwards by %ld seconds!\n", last - now); } last = now; sleep(1); } return 0; } Which when run concurrently with: # date -s 2040-1-1 # date -s 2037-1-1 Will detect the clock going backward. The root cause is that wtom_clock_sec in struct vdso_data is only a 32-bit signed value, even though we set its value to be equal to tk->wall_to_monotonic.tv_sec which is 64-bits. Because the monotonic clock starts at zero when the system boots the wall_to_montonic.tv_sec offset is negative for current and future dates. Currently on a freshly booted system the offset will be in the vicinity of negative 1.5 billion seconds. However if the wall clock is set past the Y2038 boundary, the offset from wall to monotonic becomes less than negative 2^31, and no longer fits in 32-bits. When that value is assigned to wtom_clock_sec it is truncated and becomes positive, causing the VDSO assembly code to calculate CLOCK_MONOTONIC incorrectly. That causes CLOCK_MONOTONIC to jump ahead by ~4 billion seconds which it is not meant to do. Worse, if the time is then set back before the Y2038 boundary CLOCK_MONOTONIC will jump backward. We can fix it simply by storing the full 64-bit offset in the vdso_data, and using that in the VDSO assembly code. We also shuffle some of the fields in vdso_data to avoid creating a hole. The original commit that added the CLOCK_MONOTONIC support to the VDSO did actually use a 64-bit value for wtom_clock_sec, see commit a7f290dad32e ("[PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernel") (Nov 2005). However just 3 days later it was converted to 32-bits in commit 0c37ec2aa88b ("[PATCH] powerpc: vdso fixes (take #2)"), and the bug has existed since then AFAICS.

Applications that tried to use the mmap beyond the end of the object would be greeted by a SIGBUS. After this patch, those applications will be told about the error on creating the mmap, rather than at a random moment on later access.

[PATCH] staging: vt6655: Fix interrupt race condition on device start up.

by Malcolm Priestley

It appears on some slower systems that the driver can find its way out of the workqueue while the interrupt is disabled by continuous polling by it. Move MACvIntEnable to vnt_interrupt_work so that it is always enabled on all routes out of vnt_interrupt_process. Move MACvIntDisable so that the device doesn't keep polling the system while the workqueue is being processed.
