2025-01-13wifi: mac80211: Support dynamic link addition and removalIlan Peer
Add support for adding and removing station links: - Adding links is done asynchronously, i.e., first an ML reconfiguration action frame is sent to the AP requesting to add links, and only when the AP replies, links which were added successfully by the AP are added locally. - Removing links is done synchronously, i.e., the links are removed before sending the ML reconfiguration action frame to the AP (to avoid using this links after the AP MLD removed them but before the station got the ML reconfiguration response). In case the AP replies with a status indicating that a link removal was not successful, disconnect (as this should not happen an is an indication that something might be wrong on the AP MLD).

2025-01-13wifi: mac80211: add some support for RX OMI power savingJohannes Berg
In order to save power, it can be desirable to change the RX operating mode using OMI to reduce the bandwidth. As the handshake must be done in the HTC+ field, it cannot be done by mac80211 directly, so expose functions to the driver to request and finalize the necessary updates. Note that RX OMI really only changes what the peer (AP) will transmit to us, but in order to use it to actually save some power (by reducing the listen bandwidth) we also update rate scaling and then the channel context's mindef accordingly. The updates are split into two in order to sequence them correctly, when reducing bandwidth first reduce the rate scaling and thus TX, then send OMI, then reduce the listen bandwidth (chandef); when increasing bandwidth this is the other way around. This also requires tracking in different variables which part is applicable already.

2025-01-13btrfs: zoned: reclaim unused zone by zone resettingNaohiro Aota
On the zoned mode, once used and freed region is still not reusable after the freeing. The underlying zone needs to be reset before reusing. Btrfs resets a zone when it removes a block group, and then new block group is allocated on the zones to reuse the zones. But, it is sometime too late to catch up with a write side. This commit introduces a new space-info reclaim method ZONE_RESET. That will pick a block group from the unused list and reset its zone to reuse the zone_unusable space. It is faster than removing the block group and re-creating a new block group on the same zones. For the first implementation, the ZONE_RESET is only applied to a block group whose region is fully zone_unusable. Reclaiming partial zone_unusable block group could be implemented later.

2025-01-13wifi: mac80211: change disassoc sequence a bitMiri Korenblit
Currently, the sequence goes like this (among others): 1. flush all stations (including the AP ones) -> this will tell the drivers to remove the stations 2. notify the driver the vif is not associated. Which means that in between 1 and 2, the state is that the vif is associated, but there is no AP station, which makes no sense, and may be problematic for some drivers (for example iwlwifi) Change the sequence to: 1. flush the TDLS stations 2. move the AP station to IEEE80211_STA_NONE 3. notify the driver about the vif being unassociated 4. flush the AP station In order to not break other drivers, add a vif flag to indicate whether the driver wants to new sequence or not. If the flag is not set, then things will be done in the old sequence.

2025-01-12delayacct: add delay max to record delay peakWang Yaxin
Introduce the use cases of delay max, which can help quickly detect potential abnormal delays in the system and record the types and specific details of delay spikes. Problem ======== Delay accounting can track the average delay of processes to show system workload. However, when a process experiences a significant delay, maybe a delay spike, which adversely affects performance, getdelays can only display the average system delay over a period of time. Yet, average delay is unhelpful for diagnosing delay peak. It is not even possible to determine which type of delay has spiked, as this information might be masked by the average delay. Solution ========= the 'delay max' can display delay peak since the system's startup, which can record potential abnormal delays over time, including the type of delay and the maximum delay. This is helpful for quickly identifying crash caused by delay. Use case ========= bash# ./getdelays -d -p 244 print delayacct stats ON PID 244 CPU count real total virtual total delay total delay average delay max 68 192000000 213676651 705643 0.010ms 0.306381ms IO count delay total delay average delay max 0 0 0.000ms 0.000000ms SWAP count delay total delay average delay max 0 0 0.000ms 0.000000ms RECLAIM count delay total delay average delay max 0 0 0.000ms 0.000000ms THRASHING count delay total delay average delay max 0 0 0.000ms 0.000000ms COMPACT count delay total delay average delay max 0 0 0.000ms 0.000000ms WPCOPY count delay total delay average delay max 235 15648284 0.067ms 0.263842ms IRQ count delay total delay average delay max 0 0 0.000ms 0.000000ms [wang.yaxin@zte.com.cn: update docs and fix some spelling errors] Link: https://lkml.kernel.org/r/20241213192700771XKZ8H30OtHSeziGqRVMs0@zte.com.cn Link: https://lkml.kernel.org/r/20241203164848805CS62CQPQWG9GLdQj2_BxS@zte.com.cn Co-developed-by: Wang Yong <wang.yong12@zte.com.cn> Signed-off-by: Wang Yong <wang.yong12@zte.com.cn> Co-developed-by: xu xin <xu.xin16@zte.com.cn> Signed-off-by: xu xin <xu.xin16@zte.com.cn> Co-developed-by: Wang Yaxin <wang.yaxin@zte.com.cn> Signed-off-by: Wang Yaxin <wang.yaxin@zte.com.cn> Signed-off-by: Kun Jiang <jiang.kun2@zte.com.cn> Cc: Balbir Singh <bsingharora@gmail.com> Cc: David Hildenbrand <david@redhat.com> Cc: Fan Yu <fan.yu9@zte.com.cn> Cc: Peilin He <he.peilin@zte.com.cn> Cc: tuqiang <tu.qiang35@zte.com.cn> Cc: Yang Yang <yang.yang29@zte.com.cn> Cc: ye xingchen <ye.xingchen@zte.com.cn> Cc: Yunkai Zhang <zhang.yunkai@zte.com.cn> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2025-01-12lib min_heap: improve type safety in min_heap macros by using container_ofKuan-Wei Chiu
Patch series "lib min_heap: Improve min_heap safety, testing, and documentation". Improve the min heap implementation by enhancing type safety with container_of, reducing the attack vector by replacing test function calls with inline variants, and adding a brief API introduction in min_heap.h. It also includes author information in Documentation/core-api/min_heap.rst. This patch (of 4): The current implementation of min_heap macros uses explicit casting to min_heap_char *, which prevents the compiler from detecting incorrect pointer types. This can lead to errors if non-min_heap pointers are passed inadvertently. To enhance safety, replace all explicit casts to min_heap_char * with the use of container_of(&(_heap)->nr, min_heap_char, nr). This approach ensures that the _heap parameter is indeed a min_heap_char-compatible structure, allowing the compiler to catch improper usages.

2025-01-12mm: clear uffd-wp PTE/PMD state on mremap()Ryan Roberts
When mremap()ing a memory region previously registered with userfaultfd as write-protected but without UFFD_FEATURE_EVENT_REMAP, an inconsistency in flag clearing leads to a mismatch between the vma flags (which have uffd-wp cleared) and the pte/pmd flags (which do not have uffd-wp cleared). This mismatch causes a subsequent mprotect(PROT_WRITE) to trigger a warning in page_table_check_pte_flags() due to setting the pte to writable while uffd-wp is still set. Fix this by always explicitly clearing the uffd-wp pte/pmd flags on any such mremap() so that the values are consistent with the existing clearing of VM_UFFD_WP. Be careful to clear the logical flag regardless of its physical form; a PTE bit, a swap PTE bit, or a PTE marker. Cover PTE, huge PMD and hugetlb paths.

2025-01-12module: fix writing of livepatch relocations in ROX textPetr Pavlu
A livepatch module can contain a special relocation section .klp.rela.<objname>.<secname> to apply its relocations at the appropriate time and to additionally access local and unexported symbols. When <objname> points to another module, such relocations are processed separately from the regular module relocation process. For instance, only when the target <objname> actually becomes loaded. With CONFIG_STRICT_MODULE_RWX, when the livepatch core decides to apply these relocations, their processing results in the following bug: [ 25.827238] BUG: unable to handle page fault for address: 00000000000012ba [ 25.827819] #PF: supervisor read access in kernel mode [ 25.828153] #PF: error_code(0x0000) - not-present page [ 25.828588] PGD 0 P4D 0 [ 25.829063] Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI [ 25.829742] CPU: 2 UID: 0 PID: 452 Comm: insmod Tainted: G O K 6.13.0-rc4-00078-g059dd502b263 #7820 [ 25.830417] Tainted: [O]=OOT_MODULE, [K]=LIVEPATCH [ 25.830768] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-20220807_005459-localhost 04/01/2014 [ 25.831651] RIP: 0010:memcmp+0x24/0x60 [ 25.832190] Code: [...] [ 25.833378] RSP: 0018:ffffa40b403a3ae8 EFLAGS: 00000246 [ 25.833637] RAX: 0000000000000000 RBX: ffff93bc81d8e700 RCX: ffffffffc0202000 [ 25.834072] RDX: 0000000000000000 RSI: 0000000000000004 RDI: 00000000000012ba [ 25.834548] RBP: ffffa40b403a3b68 R08: ffffa40b403a3b30 R09: 0000004a00000002 [ 25.835088] R10: ffffffffffffd222 R11: f000000000000000 R12: 0000000000000000 [ 25.835666] R13: ffffffffc02032ba R14: ffffffffc007d1e0 R15: 0000000000000004 [ 25.836139] FS: 00007fecef8c3080(0000) GS:ffff93bc8f900000(0000) knlGS:0000000000000000 [ 25.836519] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 25.836977] CR2: 00000000000012ba CR3: 0000000002f24000 CR4: 00000000000006f0 [ 25.837442] Call Trace: [ 25.838297] <TASK> [ 25.841083] __write_relocate_add.constprop.0+0xc7/0x2b0 [ 25.841701] apply_relocate_add+0x75/0xa0 [ 25.841973] klp_write_section_relocs+0x10e/0x140 [ 25.842304] klp_write_object_relocs+0x70/0xa0 [ 25.842682] klp_init_object_loaded+0x21/0xf0 [ 25.842972] klp_enable_patch+0x43d/0x900 [ 25.843572] do_one_initcall+0x4c/0x220 [ 25.844186] do_init_module+0x6a/0x260 [ 25.844423] init_module_from_file+0x9c/0xe0 [ 25.844702] idempotent_init_module+0x172/0x270 [ 25.845008] __x64_sys_finit_module+0x69/0xc0 [ 25.845253] do_syscall_64+0x9e/0x1a0 [ 25.845498] entry_SYSCALL_64_after_hwframe+0x77/0x7f [ 25.846056] RIP: 0033:0x7fecef9eb25d [ 25.846444] Code: [...] [ 25.847563] RSP: 002b:00007ffd0c5d6de8 EFLAGS: 00000246 ORIG_RAX: 0000000000000139 [ 25.848082] RAX: ffffffffffffffda RBX: 000055b03f05e470 RCX: 00007fecef9eb25d [ 25.848456] RDX: 0000000000000000 RSI: 000055b001e74e52 RDI: 0000000000000003 [ 25.848969] RBP: 00007ffd0c5d6ea0 R08: 0000000000000040 R09: 0000000000004100 [ 25.849411] R10: 00007fecefac7b20 R11: 0000000000000246 R12: 000055b001e74e52 [ 25.849905] R13: 0000000000000000 R14: 000055b03f05e440 R15: 0000000000000000 [ 25.850336] </TASK> [ 25.850553] Modules linked in: deku(OK+) uinput [ 25.851408] CR2: 00000000000012ba [ 25.852085] ---[ end trace 0000000000000000 ]--- The problem is that the .klp.rela.<objname>.<secname> relocations are processed after the module was already formed and mod->rw_copy was reset.

2025-01-12bitops: add generic parity calculation for u8Wolfram Sang
There are multiple open coded implementations for getting the parity of a byte in the kernel, even using different approaches. Take the pretty efficient version from SPD5118 driver and make it generally available by putting it into the bitops header. As long as there is just one parity calculation helper, the creation of a distinct 'parity.h' header was discarded. Also, the usage of hweight8() for architectures having a popcnt instruction is postponed until a use case within hot paths is desired. The motivation for this patch is the frequent use of odd parity in the I3C specification and to simplify drivers there. Changes compared to the original SPD5118 version are the addition of kernel documentation, switching the return type from bool to int, and renaming the argument of the function.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Pull IIO updaate from Jonathan: IIO: 1st set of new device support, features and cleanup for 6.14 Fairly quiet cycle. Usual mix of new drivers, device support in existing drivers, features and more general rework and cleanup. There are a few late breaking or long standing but complex fixes in here as well. There is one expected merge conflict due to an upstream fix touching neighboring code in ti-ads1119. The trivial resolution is the right one with the result ending up as: struct { s16 sample; aligned_s64 timestamp; } scan; New device support ================== adi,ad4000 - Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688, AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984, AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series but with lower sampling rates and no configuration registers. Includes addition of timestamp channels. adi,adis16480 - Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks to existing driver and addition of tables. kionix,kx022a - Add support for KX134ACR-LBZ accelerometer that is similar to the KX132ACR-LBZ but with a wider (+-64G) sensor range. - Add support for KX134-1211 accelerometer that is similar to the KX132-1211 but with a wider (+-16G) sensor range. nxp,fxls8962af - Add support for fxls8974cf and fxls8967af accelerometers, Both are compatible with fxls8962af but with different device IDs which are used in presence checks. renesas,rzg2l - Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors precede this to allow for chip differences). rohm,bd79704 - New driver for this 6 channel DAC. st,mpu6050 - Support he IAM20380 which is effectively a cut down IAM20608 IMU with only a gyroscope (no accelerometer). st,stm-timmer-trigger - Add support for ADC trigger use case for the STM32MP25 SOC. Do not support the counter functionality in this driver as that is handled by the counter subsystem. ti,opt4060 - New driver for this RGBW color sensor. Driver drop =========== rohm,bu20008 - Drop as decision was made to not mass produce this light sensor after Matti had done all the work to get a driver upstream. Features ======== adi,ad_sigma_delta library + ad7124 - Allow for GPIO to check interrupt status, enabling this device on more platforms that don't obey prior (non general) assumptions on how the interrupt chips work. - Allow variation in reset sequence length allowing chip specific optimizations rather than always using worst case. adi,ad7124 - Add temperature channel support. adi,ad7173 - Add support calibration modes for this family of ADCs. adi,adxl345 - Binding update to allow specification of which interrupt line is connected (or none). - Support interrupts and FIFO based data capture. bosch,bme680 - Add regulators support. Note this required a new binding doc rather than use of trivial-devices - Runtime PM support. microchip,pac1921 - Add ACPI support including _DSM for shunt value and label. renesas,rzg2l - Enable runtime autosuspend. - Add suspend and resume support. tyhx,hx9023s - Add loading of a firmware file used to set defaults for some configuration registers. vishay,veml6030 - Support triggered buffers allowing efficient data capture at higher speeds. - Add regmap cache to reduce access to device. Cleanup and minor fixes ======================= cross-tree - Another batch of conversions to devm_regulator_get_enable_read_voltage() helper and related conversions to full devm that this enables. - Various patches using guard() to allow early returns and simpler code flow. - Various conversions from s64 timestamp __aligned(8) to aligned_s64 type. Includes a few cleanups where this unsigned and it should have been signed. - Fix up some missing types for drive-open-drain in dt-binding docs. core - Add missing documentation for iio_dmaengine_buffer_setup_ext() - Add check that all buffers passed to iio_read_channel_ext_info() and iio_read_channel_label() are page sized and page aligned. Done this way because the callbacks are almost always only used to fill sysfs attributes. The check covers the tiny percentage of cases where use is made of this data in a consumer driver. - Mark scan_timestamp memory of struct iio_dev private ensuring no drivers change the value which belongs to the IIO core. documentation - Various missing ABI docs added. - ABI docs made to use Y consistently as the wildcard for channel number. - Combine duplicate in_currentY_raw entries in ABI docs. iio-mux - Fix alignment of buffers passed to iio_channel_read_ext_info(). adi,ad_sigma_delta library - Respect keep_cs_asserted flag in read path. - Close a race condition around irq enabling and disabling. - Use explicit unsigned int in place of unsigned. adi,ad6695 - Move dt-binding header under adc sub-directory and fix include path in dt example. adi,ad7124 - Check number of channels in DT doesn't exceed what the driver can handle. - Check input specified in DT are possible. - Improved error reporting during probe. adi,ad7173 - Drop unused structure element. adi,ad7293 - Ensure power is turned on before resetting. adi,adxl345 - Some documentation simplification and parameter renames. - Add a function than unifies handling of power up and power down. - Add defines to have a complete set of registers defined. - Add missing \n to end of error messages. amlogic,meson_saradc - Simplify handling of the REG11 register access. awinic,aw96104 - Constify iio_info structure. bosch,bmp085 - Add to dt-binding to indicate devices support SPI. bosch,bmp280 - Use sizeof() to replace a somewhat magic 2. - Rename sleep related variables so the unit is included and use fsleep() to replace usleep_range() calls. bosch,bno055 - Constify struct bin_attribute capella,cm3232 - Reset device before checking hardware ID inline with suggested flow from datasheet. diolan,dln2 - Simplify zeroing of structure used to gather up data by just clearing the whole thing before writing rather than trying to clear out he padding after write. freescale,vf610 - Use devm_ and dev_error_probe() to simplify code and allow dropping of explicit remove() callback. invensense,timestamp library - Use a cast to remove possibility of integer overflow. kionix,kx022a - Increase reset delay a little. maxim,max1363 - Use a buffer of sufficient size in iio_priv() rather than allocating variable sized buffer at use time. microchip,mcp4725 - Replace of_property_read_bool() with of_property_present() for detecting presence of regulator which is obviously not a bool. nxp,fxls8962af - Add wakeup-source property to the dt binding to allow these sensors to wake the system up from suspend. - Enable finer grained build when not all bus types need to be supported. renesas,rzg2l - Use dev_err_probe(), improving handling of probe errors and simplifying code. - Convert to devm_ based cleanup. - Remove unnecessary runtime PM complexity as clocks are managed through PM domains. - Switch pm_ptr() removing need for __maybe_unused markings. - use read_poll_timeout() to replace open coded equivalent. samsung, ssp_sensors - Simplify code by always providing timestamp whether or not it is enabled. st,lsm6dsx - Avoid need to include linux/i3c/master by using i3cdev_to_dev() to get to the contained struct device. st,stm32-timer-trigger - Check for clk_enable() fails. vishay,veml6030 - Use new gts-helper functions and fix the _scale attribute to take into account changes in gain and integration time.

2025-01-12ALSA: seq: Notify UMP EP and FB changesTakashi Iwai
So far we notify the sequencer client and port changes upon UMP FB changes, but those aren't really corresponding to the UMP updates. e.g. when a FB info gets updated, it's not notified but done only when some of sequencer port attribute is changed. This is no ideal behavior. This patch adds the two new sequencer event types for notifying the UMP EP and FB changes via the announce port. The new event takes snd_seq_ev_ump_notify type data, which is compatible with snd_seq_addr (where the port number is replaced with the block number). The events are sent when the EP and FB info gets updated explicitly via ioctl, or the backend UMP receives the corresponding UMP messages. The sequencer protocol version is bumped to 1.0.5 along with it. Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250110155943.31578-9-tiwai@suse.de

2025-01-11mm/slab: Move kvfree_rcu() into SLABUladzislau Rezki (Sony)
Move kvfree_rcu() functionality to the slab_common.c file. The reason to have kvfree_rcu() functionality as part of SLAB is that there is a clear trend and need of closer integration. One of the recent example is creating a barrier function for SLAB caches. Another reason is to prevent of having several implementations of RCU machinery for reclaiming objects after a GP. As future steps, it can be more integrated(easier) with SLAB internals.

2025-01-10nvmet: Implement host identifier set feature supportDamien Le Moal
The NVMe specifications mandate support for the host identifier set_features for controllers that also supports reservations. Satisfy this requirement by implementing handling of the NVME_FEAT_HOST_ID feature for the nvme_set_features command. This implementation is for now effective only for PCI target controllers. For other controller types, the set features command is failed with a NVME_SC_CMD_SEQ_ERROR status as before. As noted in the code, 128 bits host identifiers are supported since the NVMe base specifications version 2.1 indicate in section 5.1.25.1.28.1 that "The controller may support a 64-bit Host Identifier...". The RHII (Reservations and Host Identifier Interaction) bit of the controller attribute (ctratt) field of the identify controller data is also set to indicate that a host ID of "0" is supported but that the host ID must be a non-zero value to use reservations.

2025-01-10nvme: Add PCI transport typeDamien Le Moal
Define the transport type NVMF_TRTYPE_PCI for PCI endpoint targets. This transport type is defined using the value 0 which is reserved in the NVMe base specifications v2.1 (Figure 294). Given that struct nvmet_port are zeroed out on creation, to avoid having this transsport type becoming the new default, nvmet_referral_make() and nvmet_ports_make() are modified to initialize a port discovery address transport type field (disc_addr.trtype) to NVMF_TRTYPE_MAX. Any port using this transport type is also skipped and not reported in the discovery log page (nvmet_execute_disc_get_log_page()). The helper function nvmet_is_pci_ctrl() is also introduced to check if a target controller uses the PCI transport.
