stmmac: intel: Configure EHL PSE0 GbE and PSE1 GbE to 32 bits DMA addressing
Fix an issue where dump stack is printed and Reset Adapter occurs when
PSE0 GbE or/and PSE1 GbE is/are enabled. EHL PSE0 GbE and PSE1 GbE use
32 bits DMA addressing whereas EHL PCH GbE uses 64 bits DMA addressing.

A set of PI futex fixes:
- Address a longstanding issue where the user space part of the PI futex
is not writeable. The kernel returns with inconsistent state which can
in the worst case result in a UAF of a tasks kernel stack. The solution
is to establish consistent kernel state which makes future operations
on the futex fail because user space and kernel space state are
inconsistent. Not a problem as PI futexes fundamentaly require a
functional RW mapping and if user space pulls the rug under it, then it
can keep the pieces it asked for.
- Address an issue where the return value is incorrect in case that the
futex was acquired after a timeout/signal made the waiter drop out of
the rtmutex wait. In one of the corner cases the kernel returned an
error code despite having successfully acquired the futex.

On some boards the rpm interface apparently does not work at all
leading to the fan not spinning or spinning at strange speeds.
Revert this for now to fix 5.10, 5.11. The follow on patch
fixes this properly for 5.12.

The "list" of nvme_ns_head is used as rcu list, now in nvme_init_ns_head list_add_tail is used to add ns->siblings to the rcu list. It is not safe. Should use list_add_tail_rcu instead of list_add_tail. Signed-off-by: Chao Leng <lengchao@huawei.com> Signed-off-by: Christoph Hellwig <hch@lst.de> |

ARM: SoC fixes for v5.11, part 2
These are the current arm-soc bug fixes for linux-5.11. I already merged
a larger set that just came in during the past three days but has not
had much exposure in linux-next, so these are the ones I merged last week.
Most of these are for the NXP i.MX platform (descriptions from their
pull request):
- Fix pcf2127 reset for imx7d-flex-concentrator board.
- Fix i.MX6 suspend with Thumb-2 kernel.
- Fix ethernet-phy address issue on imx6qdl-sr-som board.
- Fix GPIO3 `gpio-ranges` on i.MX8MP.
- Select SOC_BUS for IMX_SCU driver to fix build issue.
- Fix backlight pwm on imx6qdl-kontron-samx6i which is lost from
#pwm-cells conversion.
- Fix duplicated bus node name for i.MX8MN SoC.
- Fix reset register offset on LS1028A SoC.
- Rename MMC node aliases for imx6q-tbs2910 to keep the MMC device
index consistent with previous kernel version.
- Selecting ARM_GIC_V3 on non-CP15 processors to fix one build failure
with i.MX8M SoC driver.
- Fix typos with status property on imx6qdl-kontron-samx6i board.
- Fix duplicated regulator-name on imx6qdl-gw52xx board.
Aside from i.MX, the bugfixes are all over the place:
- Coccinelle found a refcount imbalance on integrator
- defconfig fix for TI K3
- A boot regression fix for ST ux500
- A code preemption fix for the optee driver
- USB DMA regression on Broadcom Stingray
- A bogus boot time warning fix for at91 code

For super block version < BCACHE_SB_VERSION_CDEV_WITH_FEATURES, it doesn't make sense to check the feature sets. This patch checks super block version in bch_has_feature_* routines, if the version doesn't have feature sets yet, returns 0 (false) to the caller. Fixes: |

block: fix bd_size_lock use
Some block device drivers, e.g. the skd driver, call set_capacity() with
IRQ disabled. This results in lockdep ito complain about inconsistent
lock states ("inconsistent {HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage")
because set_capacity takes a block device bd_size_lock using the
functions spin_lock() and spin_unlock(). Ensure a consistent locking
state by replacing these calls with spin_lock_irqsave() and
spin_lock_irqrestore(). The same applies to bdev_set_nr_sectors().
With this fix, all lockdep complaints are resolved.

blk-cgroup: Use cond_resched() when destroy blkgs
On !PREEMPT kernel, we can get below softlockup when doing stress testing with creating and destroying block cgroup repeatly. The reason is it may take a long time to acquire the queue's lock in the loop of blkcg_destroy_blkgs(), or the system can accumulate a huge number of blkgs in pathological cases. We can add a need_resched() check on each loop and release locks and do cond_resched() if true to avoid this issue, since the blkcg_destroy_blkgs() is not called from atomic contexts.

iommu/vt-d: Do not use flush-queue when caching-mode is on
When an Intel IOMMU is virtualized, and a physical device is passed-through to the VM, changes of the virtual IOMMU need to be propagated to the physical IOMMU. The hypervisor therefore needs to monitor PTE mappings in the IOMMU page-tables. Intel specifications provide "caching-mode" capability that a virtual IOMMU uses to report that the IOMMU is virtualized and a TLB flush is needed after mapping to allow the hypervisor to propagate virtual IOMMU mappings to the physical IOMMU. To the best of my knowledge no real physical IOMMU reports "caching-mode" as turned on. Synchronizing the virtual and the physical IOMMU tables is expensive if the hypervisor is unaware which PTEs have changed, as the hypervisor is required to walk all the virtualized tables and look for changes. Consequently, domain flushes are much more expensive than page-specific flushes on virtualized IOMMUs with passthrough devices. The kernel therefore exploited the "caching-mode" indication to avoid domain flushing and use page-specific flushing in virtualized environments. See commit |

entry: Unbreak single step reporting behaviour
The move of TIF_SYSCALL_EMU to SYSCALL_WORK_SYSCALL_EMU broke single step
reporting. The original code reported the single step when TIF_SINGLESTEP
was set and TIF_SYSCALL_EMU was not set. The SYSCALL_WORK conversion got
the logic wrong and now the reporting only happens when both bits are set.
Restore the original behaviour.

iommu/amd: Use IVHD EFR for early initialization of IOMMU features
IOMMU Extended Feature Register (EFR) is used to communicate the supported features for each IOMMU to the IOMMU driver. This is normally read from the PCI MMIO register offset 0x30, and used by the iommu_feature() helper function. However, there are certain scenarios where the information is needed prior to PCI initialization, and the iommu_feature() function is used prematurely w/o warning. This has caused incorrect initialization of IOMMU. This is the case for the commit |

media: rockchip: rkisp1: extend uapi array sizes
Later variants of the rkisp1 block use more entries in some arrays: RKISP1_CIF_ISP_AE_MEAN_MAX 25 -> 81 RKISP1_CIF_ISP_HIST_BIN_N_MAX 16 -> 32 RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES 17 -> 34 RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE 25 -> 81 and we can still extend the uapi during the 5.11-rc cycle, so do that now to be on the safe side. V10 and V11 only need the smaller sizes, while V12 and V13 needed the larger sizes. When adding the bigger sizes make sure, values filled from hardware values and transmitted to userspace don't leak kernel data by zeroing them beforehand.

media: rockchip: rkisp1: carry ip version information
The IP block evolved from its rk3288/rk3399 base and the vendor designates them with a numerical version. rk3399 for example is designated V10 probably meaning V1.0. There doesn't seem to be an actual version register we could read that information from, so allow the match_data to carry that information for future differentiation. Also carry that information in the hw_revision field of the media- controller API, so that userspace also has access to that. The added versions are: - V10: at least rk3288 + rk3399 - V11: seemingly unused as of now, but probably appeared in some soc - V12: at least rk3326 + px30 - V13: at least rk1808 [fix checkpatch warning don't use multiple blank lines] Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Reviewed-by: Ezequiel Garcia <ezequiel@collabora.com> Acked-by: Helen Koike <helen.koike@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue
Anthony Nguyen says: ==================== Intel Wired LAN Driver Updates 2021-01-26 This series contains updates to the ice, i40e, and igc driver. Henry corrects setting an unspecified protocol to IPPROTO_NONE instead of 0 for IPv6 flexbytes filters for ice. Nick fixes the IPv6 extension header being processed incorrectly and updates the netdev->dev_addr if it exists in hardware as it may have been modified outside the ice driver. Brett ensures a user cannot request more channels than available LAN MSI-X and fixes the minimum allocation logic as it was incorrectly trying to use more MSI-X than allocated for ice. Stefan Assmann minimizes the delay between getting and using the VSI pointer to prevent a possible crash for i40e. Corinna Vinschen fixes link speed advertising for igc. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue: igc: fix link speed advertising i40e: acquire VSI pointer only after VF is initialized ice: Fix MSI-X vector fallback logic ice: Don't allow more channels than LAN MSI-X available ice: update dev_addr in ice_set_mac_address even if HW filter exists ice: Implement flow for IPv6 next header (extension header) ice: fix FDir IPv6 flexbyte ==================== Link: https://lore.kernel.org/r/20210126221035.658124-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: decnet: fix netdev refcount leaking on error path
On building the route there is an assumption that the destination could be local. In this case loopback_dev is used to get the address. If the address is still cannot be retrieved dn_route_output_slow returns EADDRNOTAVAIL with loopback_dev reference taken. Cannot find hash for the fixes tag because this code was introduced long time ago. I don't think that this bug has ever fired but the patch is done just to have a consistent code base.

net: switchdev: don't set port_obj_info->handled true when -EOPNOTSUPP
It's not true that switchdev_port_obj_notify() only inspects the ->handled field of "struct switchdev_notifier_port_obj_info" if call_switchdev_blocking_notifiers() returns 0 - there's a WARN_ON() triggering for a non-zero return combined with ->handled not being true. But the real problem here is that -EOPNOTSUPP is not being properly handled. The wrapper functions switchdev_handle_port_obj_add() et al change a return value of -EOPNOTSUPP to 0, and the treatment of ->handled in switchdev_port_obj_notify() seems to be designed to change that back to -EOPNOTSUPP in case nobody actually acted on the notifier (i.e., everybody returned -EOPNOTSUPP). Currently, as soon as some device down the stack passes the check_cb() check, ->handled gets set to true, which means that switchdev_port_obj_notify() cannot actually ever return -EOPNOTSUPP. This, for example, means that the detection of hardware offload support in the MRP code is broken: switchdev_port_obj_add() used by br_mrp_switchdev_send_ring_test() always returns 0, so since the MRP code thinks the generation of MRP test frames has been offloaded, no such frames are actually put on the wire. Similarly, br_mrp_switchdev_set_ring_role() also always returns 0, causing mrp->ring_role_offloaded to be set to 1. To fix this, continue to set ->handled true if any callback returns success or any error distinct from -EOPNOTSUPP. But if all the callbacks return -EOPNOTSUPP, make sure that ->handled stays false, so the logic in switchdev_port_obj_notify() can propagate that information. Fixes: |
