1ac5cd4 Linus Torvalds 02 January 2019, 18:46:03 UTC block: don't use un-ordered __set_current_state(TASK_UNINTERRUPTIBLE) This mostly reverts commit 849a370016a5 ("block: avoid ordered task state change for polled IO"). It was wrongly claiming that the ordering wasn't necessary. The memory barrier _is_ necessary. If something is truly polling and not going to sleep, it's the whole state setting that is unnecessary, not the memory barrier. Whenever you set your state to a sleeping state, you absolutely need the memory barrier. Note that sometimes the memory barrier can be elsewhere. For example, the ordering might be provided by an external lock, or by setting the process state to sleeping before adding yourself to the wait queue list that is used for waking up (where the wait queue lock itself will guarantee that any wakeup will correctly see the sleeping state). But none of those cases were true here. NOTE! Some of the polling paths may indeed be able to drop the state setting entirely, at which point the memory barrier also goes away. (Also note that this doesn't revert the TASK_RUNNING cases: there is no race between a wakeup and setting the process state to TASK_RUNNING, since the end result doesn't depend on ordering).

Future work: the documentation for GFP_NOFS says "Please try to avoid using this flag directly and instead use memalloc_nofs_{save,restore} to mark the whole scope which cannot/shouldn't recurse into the FS layer with a short explanation why. All allocation requests will inherit GFP_NOFS implicitly." But I'm not sure where to do this. Should the workqueue be arranging that for us in the case of workqueues created with WQ_MEM_RECLAIM?

07e1030 Chuck Lever 07 December 2018, 16:11:44 UTC xprtrdma: Prevent leak of rpcrdma_rep objects If a reply has been processed but the RPC is later retransmitted anyway, the req->rl_reply field still contains the only pointer to the old rpcrdma rep. When the next reply comes in, the reply handler will stomp on the rl_reply field, leaking the old rep. A trace event is added to capture such leaks. This problem seems to be worsened by the restructuring of the RPC Call path in v4.20. Fully addressing this issue will require at least a re-architecture of the disconnect logic, which is not appropriate during -rc.

0dfbb5f Chuck Lever 19 December 2018, 15:59:12 UTC NFS: Make "port=" mount option optional for RDMA mounts Having to specify "proto=rdma,port=20049" is cumbersome. RFC 8267 Section 6.3 requires NFSv4 clients to use "the alternative well-known port number", which is 20049. Make the use of the well- known port number automatic, just as it is for NFS/TCP and port 2049. For NFSv2/3, Section 4.2 allows clients to simply choose 20049 as the default or use rpcbind. I don't know of an NFS/RDMA server implementation that registers it's NFS/RDMA service with rpcbind, so automatically choosing 20049 seems like the better choice. The other widely-deployed NFS/RDMA client, Solaris, also uses 20049 as the default port.

There are two reasons to do this: - The R_key only has 8 bits that are different from registration to registration. The XID adds more uniqueness to each RDMA segment to reduce the likelihood of a software bug on the server reading from or writing into memory it's not supposed to. - On-the-wire RDMA Read and Write requests do not otherwise carry any identifier that matches them up to an RPC. The XID in the upper 32 bits will act as an eye-catcher in network captures.

ba69cd1 Chuck Lever 19 December 2018, 15:58:56 UTC xprtrdma: Remove support for FMR memory registration FMR is not supported on most recent RDMA devices. It is also less secure than FRWR because an FMR memory registration can expose adjacent bytes to remote reading or writing. As discussed during the RDMA BoF at LPC 2018, it is time to remove support for FMR in the NFS/RDMA client stack. Note that NFS/RDMA server-side uses either local memory registration or FRWR. FMR is not used. There are a few Infiniband/RoCE devices in the kernel tree that do not appear to support MEM_MGT_EXTENSIONS (FRWR), and therefore will not support client-side NFS/RDMA after this patch. These are: - mthca - qib - hns (RoCE) Users of these devices can use NFS/TCP on IPoIB instead.

a788684 Chuck Lever 19 December 2018, 15:58:51 UTC xprtrdma: Reduce max_frwr_depth Some devices advertise a large max_fast_reg_page_list_len capability, but perform optimally when MRs are significantly smaller than that depth -- probably when the MR itself is no larger than a page. By default, the RDMA R/W core API uses max_sge_rd as the maximum page depth for MRs. For some devices, the value of max_sge_rd is 1, which is also not optimal. Thus, when max_sge_rd is larger than 1, use that value. Otherwise use the value of the max_fast_reg_page_list_len attribute. I've tested this with CX-3 Pro, FastLinq, and CX-5 devices. It reproducibly improves the throughput of large I/Os by several percent.

This is because the calculated value of ri_max_segs (the max number of MRs per RPC) exceeded RPCRDMA_MAX_HDR_SEGS, which caused Read or Write list encoding to walk off the end of the transport header. Once that was addressed, the ro_maxpages result has to be corrected to account for the number of MRs needed for Reply chunks, which is 2 MRs smaller than a normal Read or Write chunk.

0c0829b Chuck Lever 19 December 2018, 15:58:40 UTC xprtrdma: Don't wake pending tasks until disconnect is done Transport disconnect processing does a "wake pending tasks" at various points. Suppose an RPC Reply is being processed. The RPC task that Reply goes with is waiting on the pending queue. If a disconnect wake-up happens before reply processing is done, that reply, even if it is good, is thrown away, and the RPC has to be sent again. This window apparently does not exist for socket transports because there is a lock held while a reply is being received which prevents the wake-up call until after reply processing is done. To resolve this, all RPC replies being processed on an RPC-over-RDMA transport have to complete before pending tasks are awoken due to a transport disconnect. Callers that already hold the transport write lock may invoke ->ops->close directly. Others use a generic helper that schedules a close when the write lock can be taken safely.

Actually the two have only an indirect relationship. It's in fact impossible to guess reliably whether the MR has been DMA unmapped based on its fr_state field, especially as the surrounding code and its assumptions have changed over time. A better approach is to track the DMA mapping status explicitly so that the recycler is less brittle to unexpected situations, and attempts to DMA-unmap a second time are prevented.

Most of these have been covered and described in the other branches, we mostly keep defconfig separate to avoid conflicts between SoC/dt/driver updates that they otherwise would be grouped with. One thing worth mentioning here is that OMAP changes from using their own UART driver, to 8250, for the multi_v7_defconfig shared config on 32-bit. This means that the console is now named ttyS* instead of ttyO*. This change was already done for omap2_defconfig a while back, so most users of these configs have either already updated, or can easily follow the same patterns as they did at that time.

The individual updates are too many to enumerate, many many platforms have seen additions of device descriptions such that they are functionally more complete (in fact, this is often the bulk of updates we see). Instead I've mostly focused on highlighting the new platforms below as they are introduced. Sometimes the introduction is of mostly a fragment, that later gets filled in on later releases, and in some cases it's near-complete platform support. The latter is more common for derivative platforms that already has similar support in-tree. Two SoCs are slight outliers from the usual range of additions. Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping in the Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at infrastructure/networking. TI updates stick out in the diff stats too, in particular because they have moved the description of their L4 on-chip interconnect to devicetree, which opens up for removal of even more of their platform-specific 'hwmod' description tables over the next few releases. SoCs: - Qualcomm QCS404 (4x Cortex-A53) - Allwinner T3 (rebranded R40) and f1c100s (armv5) - NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4) - NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72) New platforms: - Rockchip: Gru Scarlet (RK3188 Tablet) - Amlogic: Phicomm N1 (S905D), Libretech S805-AC - Broadcom: Linksys EA6500 v2 Wi-Fi router (BCM4708) - Qualcomm: QCS404 base platform and EVB - Qualcomm: Remove of Arrow SD600 - PXA: First PXA3xx DT board: Raumfeld - Aspeed: Facebook Backpack-CMM BMC - Renesas iWave G20D-Q7 (RZ/G1N) - Allwinner t3-cqa3t-bv3 (T3/R40) and Lichee Pi Nano (F1C100s) - Allwinner Emlid Neutis N5, Mapleboard MP130 - Marvell Macchiatobin Single Shot (Armada 8040, no 10GbE) - i.MX: mtrion emCON-MX6, imx6ul-pico-pi, imx7d-sdb-reva - VF610: Liebherr's BK4 device, ZII SCU4 AIB board - i.MX7D PICO Hobbit baseboard - i.MX7ULP EVK board - NXP LX2160AQDS and LX2160ARDB boards Other: - Coresight binding updates across the board - CPU cooling maps updates across the board" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (648 commits) ARM: dts: suniv: Fix improper bindings include patch ARM: dts: sunxi: Enable Broadcom-based Bluetooth for multiple boards arm64: dts: allwinner: a64: bananapi-m64: Add Bluetooth device node ARM: dts: suniv: Fix improper bindings include patch arm64: dts: Add spi-[tx/rx]-bus-width for the FSL QSPI controller arm64: dts: Remove unused properties from FSL QSPI driver nodes ARM: dts: Add spi-[tx/rx]-bus-width for the FSL QSPI controller ARM: dts: imx6sx-sdb: Fix the reg properties for the FSL QSPI nodes ARM: dts: Remove unused properties from FSL QSPI driver nodes arm64: dts: ti: k3-am654: Enable main domain McSPI0 arm64: dts: ti: k3-am654: Add McSPI DT nodes arm64: dts: ti: k3-am654: Populate power-domain property for UART nodes arm64: dts: ti: k3-am654-base-board: Enable ECAP PWM arm64: dts: ti: k3-am65-main: Add ECAP PWM node arm64: dts: ti: k3-am654-base-board: Add I2C nodes arm64: dts: ti: am654-base-board: Add pinmux for main uart0 arm64: dts: ti: k3-am65: Add pinctrl regions dt-bindings: pinctrl: k3: Introduce pinmux definitions ARM: dts: exynos: Specify I2S assigned clocks in proper node ARM: dts: exynos: Add missing CPUs in cooling maps for Odroid X2 ... 01 January 2019, 01:36:02 UTC

That commit added a struct blk_mq_tag_set to struct floppy_state and initialized it with a blk_mq_init_sq_queue() call. Unfortunately, there is a memset() in swim3_add_device() that subsequently clears the floppy_state struct. That means fs->tag_set->ops is a NULL pointer, and it gets dereferenced by blk_mq_free_rqs() which gets called in the request_irq() error path. Move the memset() to fix this bug. BTW, the request_irq() failure for the left mediabay floppy (fd1) is not a regression. I don't know why it happens. The right media bay floppy (fd0) works fine however.

c40f7d7 Linus Torvalds 27 December 2018, 21:46:17 UTC sched/fair: Fix infinite loop in update_blocked_averages() by reverting a9e7f6544b9c Zhipeng Xie, Xie XiuQi and Sargun Dhillon reported lockups in the scheduler under high loads, starting at around the v4.18 time frame, and Zhipeng Xie tracked it down to bugs in the rq->leaf_cfs_rq_list manipulation. Do a (manual) revert of: a9e7f6544b9c ("sched/fair: Fix O(nr_cgroups) in load balance path") It turns out that the list_del_leaf_cfs_rq() introduced by this commit is a surprising property that was not considered in followup commits such as: 9c2791f936ef ("sched/fair: Fix hierarchical order in rq->leaf_cfs_rq_list") As Vincent Guittot explains: "I think that there is a bigger problem with commit a9e7f6544b9c and cfs_rq throttling: Let take the example of the following topology TG2 --> TG1 --> root: 1) The 1st time a task is enqueued, we will add TG2 cfs_rq then TG1 cfs_rq to leaf_cfs_rq_list and we are sure to do the whole branch in one path because it has never been used and can't be throttled so tmp_alone_branch will point to leaf_cfs_rq_list at the end. 2) Then TG1 is throttled 3) and we add TG3 as a new child of TG1. 4) The 1st enqueue of a task on TG3 will add TG3 cfs_rq just before TG1 cfs_rq and tmp_alone_branch will stay on rq->leaf_cfs_rq_list. With commit a9e7f6544b9c, we can del a cfs_rq from rq->leaf_cfs_rq_list. So if the load of TG1 cfs_rq becomes NULL before step 2) above, TG1 cfs_rq is removed from the list. Then at step 4), TG3 cfs_rq is added at the beginning of rq->leaf_cfs_rq_list but tmp_alone_branch still points to TG3 cfs_rq because its throttled parent can't be enqueued when the lock is released. tmp_alone_branch doesn't point to rq->leaf_cfs_rq_list whereas it should. So if TG3 cfs_rq is removed or destroyed before tmp_alone_branch points on another TG cfs_rq, the next TG cfs_rq that will be added, will be linked outside rq->leaf_cfs_rq_list - which is bad. In addition, we can break the ordering of the cfs_rq in rq->leaf_cfs_rq_list but this ordering is used to update and propagate the update from leaf down to root." Instead of trying to work through all these cases and trying to reproduce the very high loads that produced the lockup to begin with, simplify the code temporarily by reverting a9e7f6544b9c - which change was clearly not thought through completely. This (hopefully) gives us a kernel that doesn't lock up so people can continue to enjoy their holidays without worrying about regressions. ;-) [ mingo: Wrote changelog, fixed weird spelling in code comment while at it. ] Analyzed-by: Xie XiuQi <xiexiuqi@huawei.com> Analyzed-by: Vincent Guittot <vincent.guittot@linaro.org> Reported-by: Zhipeng Xie <xiezhipeng1@huawei.com> Reported-by: Sargun Dhillon <sargun@sargun.me> Reported-by: Xie XiuQi <xiexiuqi@huawei.com> Tested-by: Zhipeng Xie <xiezhipeng1@huawei.com> Tested-by: Sargun Dhillon <sargun@sargun.me> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Vincent Guittot <vincent.guittot@linaro.org> Cc: <stable@vger.kernel.org> # v4.13+ Cc: Bin Li <huawei.libin@huawei.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Tejun Heo <tj@kernel.org> Cc: Thomas Gleixner <tglx@linutronix.de> Fixes: a9e7f6544b9c ("sched/fair: Fix O(nr_cgroups) in load balance path") Link: http://lkml.kernel.org/r/1545879866-27809-1-git-send-email-xiexiuqi@huawei.com Signed-off-by: Ingo Molnar <mingo@kernel.org> 30 December 2018, 12:54:31 UTC
