2023-11-13ice: dpll: fix output pin capabilitiesArkadiusz Kubalewski
The dpll output pins which are used to feed clock signal of PHY and MAC circuits cannot be disconnected, those integrated circuits require clock signal for operation. By stopping assignment of DPLL_PIN_CAPABILITIES_STATE_CAN_CHANGE pin capability, prevent the user from invoking the state set callback on those pins, setting the state on those pins already returns error, as firmware doesn't allow the change of their state.

2023-11-13ice: dpll: fix check for dpll input priority rangeArkadiusz Kubalewski
Supported priority value for input pins may differ with regard of NIC firmware version. E810T NICs with 3.20/4.00 FW versions would accept priority range 0-31, where firmware 4.10+ would support the range 0-9 and extra value of 255. Remove the in-range check as the driver has no information on supported values from the running firmware, let firmware decide if given value is correct and return extack error if the value is not supported.

2023-11-13ice: dpll: fix initial lock status of dpllArkadiusz Kubalewski
When dpll device is registered and dpll subsystem performs notify of a new device, the lock state value provided to dpll subsystem equals 0 which is invalid value for the `enum dpll_lock_status`. Provide correct value by obtaining it from firmware before registering the dpll device.

2023-11-13i2c: ocores: Move system PM hooks to the NOIRQ phaseSamuel Holland
When an I2C device contains a wake IRQ subordinate to a regmap-irq chip, the regmap-irq code must be able to perform I2C transactions during suspend_device_irqs() and resume_device_irqs(). Therefore, the bus must be suspended/resumed during the NOIRQ phase.

2023-11-13drm/ci: make github dependabot happy againLinus Torvalds
The drm CI scripts for gitlab have a requirements file that makes the github 'dependabot' worry about a few of the required tooling versions. It wants to update the pip requirements from 23.2.1 to 23.3: "When installing a package from a Mercurial VCS URL, e.g. pip install hg+..., with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the hg clone call (e.g. --config). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial" and upgrade the urllib3 requirements from 2.0.4 to 2.0.7 due to two issues: "urllib3's request body not stripped after redirect from 303 status changes request method to GET" "`Cookie` HTTP header isn't stripped on cross-origin redirects" The file also ends up not having a newline at the end, that my editor ends up wanting to fix automatically.

2023-11-13ALSA: hda: cs35l56: Enable low-power hibernation mode on i2cSimon Trimmer
This can now be re-enabled as the sequence to reliably wake the device has been implemented in the shared ASoC code. This has a functional dependency on commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.

2023-11-13xen/events: fix delayed eoi list handlingJuergen Gross
When delaying eoi handling of events, the related elements are queued into the percpu lateeoi list. In case the list isn't empty, the elements should be sorted by the time when eoi handling is to happen. Unfortunately a new element will never be queued at the start of the list, even if it has a handling time lower than all other list elements.

2023-11-13ppp: limit MRU to 64KWillem de Bruijn
ppp_sync_ioctl allows setting device MRU, but does not sanity check this input. Limit to a sane upper bound of 64KB. No implementation I could find generates larger than 64KB frames. RFC 2823 mentions an upper bound of PPP over SDL of 64KB based on the 16-bit length field. Other protocols will be smaller, such as PPPoE (9KB jumbo frame) and PPPoA (18190 maximum CPCS-SDU size, RFC 2364). PPTP and L2TP encapsulate in IP.

2023-11-13net: mvneta: fix calls to page_pool_get_statsSven Auhagen
Calling page_pool_get_stats in the mvneta driver without checks leads to kernel crashes. First the page pool is only available if the bm is not used. The page pool is also not allocated when the port is stopped. It can also be not allocated in case of errors. The current implementation leads to the following crash calling ethstats on a port that is down or when calling it at the wrong moment: ble to handle kernel NULL pointer dereference at virtual address 00000070 [00000070] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Hardware name: Marvell Armada 380/385 (Device Tree) PC is at page_pool_get_stats+0x18/0x1cc LR is at mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] pc : [<c0b413cc>] lr : [<bf0a98d8>] psr: a0000013 sp : f1439d48 ip : f1439dc0 fp : 0000001d r10: 00000100 r9 : c4816b80 r8 : f0d75150 r7 : bf0b400c r6 : c238f000 r5 : 00000000 r4 : f1439d68 r3 : c2091040 r2 : ffffffd8 r1 : f1439d68 r0 : 00000000 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 066b004a DAC: 00000051 Register r0 information: NULL pointer Register r1 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r2 information: non-paged memory Register r3 information: slab kmalloc-2k start c2091000 pointer offset 64 size 2048 Register r4 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r5 information: NULL pointer Register r6 information: slab kmalloc-cg-4k start c238f000 pointer offset 0 size 4096 Register r7 information: 15-page vmalloc region starting at 0xbf0a8000 allocated at load_module+0xa30/0x219c Register r8 information: 1-page vmalloc region starting at 0xf0d75000 allocated at ethtool_get_stats+0x138/0x208 Register r9 information: slab task_struct start c4816b80 pointer offset 0 Register r10 information: non-paged memory Register r11 information: non-paged memory Register r12 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Process snmpd (pid: 733, stack limit = 0x38de3a88) Stack: (0xf1439d48 to 0xf143a000) 9d40: 000000c0 00000001 c238f000 bf0b400c f0d75150 c4816b80 9d60: 00000100 bf0a98d8 00000000 00000000 00000000 00000000 00000000 00000000 9d80: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9da0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9dc0: 00000dc0 5335509c 00000035 c238f000 bf0b2214 01067f50 f0d75000 c0b9b9c8 9de0: 0000001d 00000035 c2212094 5335509c c4816b80 c238f000 c5ad6e00 01067f50 9e00: c1b0be80 c4816b80 00014813 c0b9d7f0 00000000 00000000 0000001d 0000001d 9e20: 00000000 00001200 00000000 00000000 c216ed90 c73943b8 00000000 00000000 9e40: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9e60: 00000000 c0ad9034 00000000 00000000 00000000 00000000 00000000 00000000 9e80: 00000000 00000000 00000000 5335509c c1b0be80 f1439ee4 00008946 c1b0be80 9ea0: 01067f50 f1439ee3 00000000 00000046 b6d77ae0 c0b383f0 00008946 becc83e8 9ec0: c1b0be80 00000051 0000000b c68ca480 c7172d00 c0ad8ff0 f1439ee3 cf600e40 9ee0: 01600e40 32687465 00000000 00000000 00000000 01067f50 00000000 00000000 9f00: 00000000 5335509c 00008946 00008946 00000000 c68ca480 becc83e8 c05e2de0 9f20: f1439fb0 c03002f0 00000006 5ac3c35a c4816b80 00000006 b6d77ae0 c030caf0 9f40: c4817350 00000014 f1439e1c 0000000c 00000000 00000051 01000000 00000014 9f60: 00003fec f1439edc 00000001 c0372abc b6d77ae0 c0372abc cf600e40 5335509c 9f80: c21e6800 01015c9c 0000000b 00008946 00000036 c03002f0 c4816b80 00000036 9fa0: b6d77ae0 c03000c0 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 40000030 0000000b 00000000 00000000 page_pool_get_stats from mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] mvneta_ethtool_get_stats [mvneta] from ethtool_get_stats+0x154/0x208 ethtool_get_stats from dev_ethtool+0xf48/0x2480 dev_ethtool from dev_ioctl+0x538/0x63c dev_ioctl from sock_ioctl+0x49c/0x53c sock_ioctl from sys_ioctl+0x134/0xbd8 sys_ioctl from ret_fast_syscall+0x0/0x1c Exception stack(0xf1439fa8 to 0xf1439ff0) 9fa0: 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 Code: e28dd004 e1a05000 e2514000 0a00006a (e5902070) This commit adds the proper checks before calling page_pool_get_stats.

This size is calculated with TLV_SPACE() macro. It adds the size of struct tlv_desc and the length of TLV value passed as an argument, and aligns the result to a multiple of TLV_ALIGNTO, i.e., a multiple of 4 bytes.

2023-11-13i2c: designware: Fix corrupted memory seen in the ISRJan Bottorff
When running on a many core ARM64 server, errors were happening in the ISR that looked like corrupted memory. These corruptions would fix themselves if small delays were inserted in the ISR. Errors reported by the driver included "i2c_designware APMC0D0F:00: i2c_dw_xfer_msg: invalid target address" and "i2c_designware APMC0D0F:00:controller timed out" during in-band IPMI SSIF stress tests. The problem was determined to be memory writes in the driver were not becoming visible to all cores when execution rapidly shifted between cores, like when a register write immediately triggers an ISR. Processors with weak memory ordering, like ARM64, make no guarantees about the order normal memory writes become globally visible, unless barrier instructions are used to control ordering. To solve this, regmap accessor functions configured by this driver were changed to use non-relaxed forms of the low-level register access functions, which include a barrier on platforms that require it. This assures memory writes before a controller register access are visible to all cores. The community concluded defaulting to correct operation outweighed defaulting to the small performance gains from using relaxed access functions. Being a low speed device added weight to this choice of default register access behavior.

2023-11-13net: hns3: fix VF wrong speed and duplex issueJijie Shao
If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode when PF queries the port information from firmware. After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF. This patch fixes it by updating port information before PF synchronizes the rate and duplex to the VF when PF changes to up.

2023-11-13acpi/processor: sanitize _OSC/_PDC capabilities for Xen dom0Roger Pau Monne
The Processor capability bits notify ACPI of the OS capabilities, and so ACPI can adjust the return of other Processor methods taking the OS capabilities into account. When Linux is running as a Xen dom0, the hypervisor is the entity in charge of processor power management, and hence Xen needs to make sure the capabilities reported by _OSC/_PDC match the capabilities of the driver in Xen. Introduce a small helper to sanitize the buffer when running as Xen dom0. When Xen supports HWP, this serves as the equivalent of commit a21211672c9a ("ACPI / processor: Request native thermal interrupt handling via _OSC") to avoid SMM crashes. Xen will set bit ACPI_PROC_CAP_COLLAB_PROC_PERF (bit 12) in the capability bits and the _OSC/_PDC call will apply it. [ jandryuk: Mention Xen HWP's need.

Unfortunately xen_send_IPI_one() is using notify_remote_via_irq() today, which is using irq_get_chip_data() via info_for_irq(). And irq_get_chip_data() in turn is using a maple-tree lookup requiring RCU. Avoid this problem by caching the ipi event channels in another percpu variable, allowing the use notify_remote_via_evtchn() in xen_send_IPI_one().

2023-11-13xfs: recovery should not clear di_flushiter unconditionallyDave Chinner
Because on v3 inodes, di_flushiter doesn't exist. It overlaps with zero padding in the inode, except when NREXT64=1 configurations are in use and the zero padding is no longer padding but holds the 64 bit extent counter. This manifests obviously on big endian platforms (e.g. s390) because the log dinode is in host order and the overlap is the LSBs of the extent count field. It is not noticed on little endian machines because the overlap is at the MSB end of the extent count field and we need to get more than 2^^48 extents in the inode before it manifests. i.e. the heat death of the universe will occur before we see the problem in little endian machines. This is a zero-day issue for NREXT64=1 configuraitons on big endian machines. Fix it by only clearing di_flushiter on v2 inodes during recovery.

2023-11-13xfs: fix internal error from AGFL exhaustionOmar Sandoval
We've been seeing XFS errors like the following: XFS: Internal error i != 1 at line 3526 of file fs/xfs/libxfs/xfs_btree.c. Caller xfs_btree_insert+0x1ec/0x280 ...

This is the XFS_IS_CORRUPT() check in xfs_btree_insert() when xfs_btree_insrec() fails. After converting this into a panic and dissecting the core dump, I found that xfs_btree_insrec() is failing because it's trying to split a leaf node in the cntbt when the AG free list is empty. In particular, it's failing to get a block from the AGFL _while trying to refill the AGFL_. If a single operation splits every level of the bnobt and the cntbt (and the rmapbt if it is enabled) at once, the free list will be empty. Then, when the next operation tries to refill the free list, it allocates space. If the allocation does not use a full extent, it will need to insert records for the remaining space in the bnobt and cntbt. And if those new records go in full leaves, the leaves (and potentially more nodes up to the old root) need to be split. Fix it by accounting for the additional splits that may be required to refill the free list in the calculation for the minimum free list size. P.S. As far as I can tell, this bug has existed for a long time -- maybe back to xfs-history commit afdf80ae7405 ("Add XFS_AG_MAXLEVELS macros ...") in April 1994! It requires a very unlucky sequence of events, and in fact we didn't hit it until a particular sparse mmap workload updated from 5.12 to 5.19. But this bug existed in 5.12, so it must've been exposed by some other change in allocation or writeback patterns. It's also much less likely to be hit with the rmapbt enabled, since that increases the minimum free list size and is unlikely to split at the same time as the bnobt and cntbt.

2023-11-13xfs: only remap the written blocks in xfs_reflink_end_cow_extentChristoph Hellwig
xfs_reflink_end_cow_extent looks up the COW extent and the data fork extent at offset_fsb, and then proceeds to remap the common subset between the two. It does however not limit the remapped extent to the passed in [*offset_fsbm end_fsb] range and thus potentially remaps more blocks than the one handled by the current I/O completion. This means that with sufficiently large data and COW extents we could be remapping COW fork mappings that have not been written to, leading to a stale data exposure on a powerfail event. We use to have a xfs_trim_range to make the remap fit the I/O completion range, but that got (apparently accidentally) removed in commit df2fd88f8ac7 ("xfs: rewrite xfs_reflink_end_cow to use intents").

2023-11-12Revert "i2c: pxa: move to generic GPIO recovery"Robert Marko
This reverts commit 0b01392c18b9993a584f36ace1d61118772ad0ca. Conversion of PXA to generic I2C recovery, makes the I2C bus completely lock up if recovery pinctrl is present in the DT and I2C recovery is enabled. So, until the generic I2C recovery can also work with PXA lets revert to have working I2C and I2C recovery again.

2023-11-11hrtimers: Push pending hrtimers away from outgoing CPU earlierThomas Gleixner
2b8272ff4a70 ("cpu/hotplug: Prevent self deadlock on CPU hot-unplug") solved the straight forward CPU hotplug deadlock vs. the scheduler bandwidth timer. Yu discovered a more involved variant where a task which has a bandwidth timer started on the outgoing CPU holds a lock and then gets throttled. If the lock required by one of the CPU hotplug callbacks the hotplug operation deadlocks because the unthrottling timer event is not handled on the dying CPU and can only be recovered once the control CPU reaches the hotplug state which pulls the pending hrtimers from the dead CPU. Solve this by pushing the hrtimers away from the dying CPU in the dying callbacks. Nothing can queue a hrtimer on the dying CPU at that point because all other CPUs spin in stop_machine() with interrupts disabled and once the operation is finished the CPU is marked offline.
