2020-08-07tools/: replace HTTP links with HTTPS onesAlexander A. Klimov5-5/+5
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Signed-off-by: Alexander A.

2020-08-07kthread: remove incorrect comment in kthread_create_on_cpu()Ilias Stamatis1-1/+0
Originally kthread_create_on_cpu() parked and woke up the new thread. However, since commit a65d40961dc7 ("kthread/smpboot: do not park in kthread_create_on_cpu()") this is no longer the case. This patch removes the comment that has been left behind and is now incorrect / stale.

2020-08-07mm: fix kthread_use_mm() vs TLB invalidatePeter Zijlstra1-1/+6
For SMP systems using IPI based TLB invalidation, looking at current->active_mm is entirely reasonable. This then presents the following race condition: CPU0 CPU1 flush_tlb_mm(mm) use_mm(mm) <send-IPI> tsk->active_mm = mm; <IPI> if (tsk->active_mm == mm) // flush TLBs </IPI> switch_mm(old_mm,mm,tsk); Where it is possible the IPI flushed the TLBs for @old_mm, not @mm, because the IPI lands before we actually switched. Avoid this by disabling IRQs across changing ->active_mm and switch_mm(). Of the (SMP) architectures that have IPI based TLB invalidate: Alpha - checks active_mm ARC - ASID specific IA64 - checks active_mm MIPS - ASID specific flush OpenRISC - shoots down world PARISC - shoots down world SH - ASID specific SPARC - ASID specific x86 - N/A xtensa - checks active_mm So at the very least Alpha, IA64 and Xtensa are suspect. On top of this, for scheduler consistency we need at least preemption disabled across changing tsk->mm and doing switch_mm(), which is currently provided by task_lock(), but that's not sufficient for PREEMPT_RT.

2020-08-07mm/shuffle: don't move pages between zones and don't read garbage memmapsDavid Hildenbrand1-9/+9
Especially with memory hotplug, we can have offline sections (with a garbage memmap) and overlapping zones. We have to make sure to only touch initialized memmaps (online sections managed by the buddy) and that the zone matches, to not move pages between zones. To test if this can actually happen, I added a simple BUG_ON(page_zone(page_i) != page_zone(page_j)); right before the swap. When hotplugging a 256M DIMM to a 4G x86-64 VM and onlining the first memory block "online_movable" and the second memory block "online_kernel", it will trigger the BUG, as both zones (NORMAL and MOVABLE) overlap. This might result in all kinds of weird situations (e.g., double allocations, list corruptions, unmovable allocations ending up in the movable zone).

2020-08-06Revert "x86/mm/64: Do not sync vmalloc/ioremap mappings"Linus Torvalds2-0/+7
This reverts commit 8bb9bf242d1fee925636353807c511d54fde8986. It seems the vmalloc page tables aren't always preallocated in all situations, because Jason Donenfeld reports an oops with this commit: BUG: unable to handle page fault for address: ffffe8ffffd00608 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP CPU: 2 PID: 22 Comm: kworker/2:0 Not tainted 5.8.0+ #154 RIP: process_one_work+0x2c/0x2d0 Code: 41 56 41 55 41 54 55 48 89 f5 53 48 89 fb 48 83 ec 08 48 8b 06 4c 8b 67 40 49 89 c6 45 30 f6 a8 04 b8 00 00 00 00 4c 0f 44 f0 <49> 8b 46 08 44 8b a8 00 01 05 Call Trace: worker_thread+0x4b/0x3b0 ? rescuer_thread+0x360/0x360 kthread+0x116/0x140 ? __kthread_create_worker+0x110/0x110 ret_from_fork+0x1f/0x30 CR2: ffffe8ffffd00608 and that page fault address is right in that vmalloc space, and we clearly don't have a PGD/P4D entry for it. Looking at the "Code:" line, the actual fault seems to come from the 'pwq->wq' dereference at the top of the process_one_work() function: struct pool_workqueue *pwq = get_work_pwq(work); struct worker_pool *pool = worker->pool; bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE; so 'struct pool_workqueue *pwq' is the allocation that hasn't been synchronized across CPUs. Just revert for now, while Joerg figures out the cause. Reported-and-bisected-by: Jason A.

The msg_zerocopy test pins the sender and receiver threads to separate cores to reduce variance between runs. But it hardcodes the cores and skips core 0, so it fails on machines with the selected cores offline, or simply fewer cores. The test mainly gives code coverage in automated runs. The throughput of zerocopy ('-z') and non-zerocopy runs is logged for manual inspection. Continue even when sched_setaffinity fails. Just log to warn anyone interpreting the data.

2020-08-05net: dsa: sja1105: use detected device id instead of DT one on mismatchVladimir Oltean1-11/+24
Although we can detect the chip revision 100% at runtime, it is useful to specify it in the device tree compatible string too, because otherwise there would be no way to assess the correctness of device tree bindings statically, without booting a board (only some switch versions have internal RGMII delays and/or an SGMII port). But for testing the P/Q/R/S support, what I have is a reworked board with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't want to keep a separate device tree blob just for this one-off board. Since just the chip has been replaced, its RGMII delay setup is inherently the same (meaning: delays added by the PHY on the slave ports, and by PCB traces on the fixed-link CPU port). For this board, I'd rather have the driver shout at me, but go ahead and use what it found even if it doesn't match what it's been told is there.
