2023-12-29xfs: remove xfs_attr_shortform_lookupChristoph Hellwig
xfs_attr_shortform_lookup is only used by xfs_attr_shortform_addname, which is much better served by calling xfs_attr_sf_findname. Switch it over and remove xfs_attr_shortform_lookup.

2023-12-29xfs: simplify xfs_attr_sf_findnameChristoph Hellwig
xfs_attr_sf_findname has the simple job of finding a xfs_attr_sf_entry in the attr fork, but the convoluted calling convention obfuscates that. Return the found entry as the return value instead of an pointer argument, as the -ENOATTR/-EEXIST can be trivally derived from that, and remove the basep argument, as it is equivalent of the offset of sfe in the data for if an sfe was found, or an offset of totsize if not was found. To simplify the totsize computation add a xfs_attr_sf_endptr helper that returns the imaginative xfs_attr_sf_entry at the end of the current attrs.

2023-12-29xfs: make if_data a void pointerChristoph Hellwig
The xfs_ifork structure currently has a union of the if_root void pointer and the if_data char pointer. In either case it is an opaque pointer that depends on the fork format. Replace the union with a single if_data void pointer as that is what almost all callers want. Only the symlink NULL termination code in xfs_init_local_fork actually needs a new local variable now.

2023-12-28mm/slub: free KFENCE objects in slab_free_hook()Vlastimil Babka
When freeing an object that was allocated from KFENCE, we do that in the slowpath __slab_free(), relying on the fact that KFENCE "slab" cannot be the cpu slab, so the fastpath has to fallback to the slowpath. This optimization doesn't help much though, because is_kfence_address() is checked earlier anyway during the free hook processing or detached freelist building. Thus we can simplify the code by making the slab_free_hook() free the KFENCE object immediately, similarly to KASAN quarantine. In slab_free_hook() we can place kfence_free() above init processing, as callers have been making sure to set init to false for KFENCE objects. This simplifies slab_free(). This places it also above kasan_slab_free() which is ok as that skips KFENCE objects anyway. While at it also determine the init value in slab_free_freelist_hook() outside of the loop. This change will also make introducing per cpu array caches easier.

2023-12-28thermal: core: Resume thermal zones asynchronouslyRafael J. Wysocki
The resume of thermal zones in thermal_pm_notify() is carried out sequentially, which may be a problem if __thermal_zone_device_update() takes a significant time to run for some thermal zones, because some other thermal zones may need to wait for them to resume then and if any other PM notifiers are going to be invoked after the thermal one, they will need to wait for it either. To address this, make thermal_pm_notify() switch the poll_queue delayed work over to a one-shot thermal_zone_device_resume() work function that will restore the original one during the thermal zone resume and queue up poll_queue without a delay for each thermal zone.

In preparation for a subsequent change, move the initialization of the poll_queue delayed work from thermal_zone_device_register_with_trips() to thermal_zone_device_init() which is called by the former. However, because thermal_zone_device_init() is also called by thermal_pm_notify(), make the latter call cancel_delayed_work() on poll_queue before invoking the former, so as to allow the work item to be re-initialized safely. Also move thermal_zone_device_check() which needs to be defined before thermal_zone_device_init(), so the latter can pass it to the INIT_DELAYED_WORK() macro. Signed-off-by: Rafael J.

2023-12-28thermal: core: Fix thermal zone suspend-resume synchronizationRafael J. Wysocki
There are 3 synchronization issues with thermal zone suspend-resume during system-wide transitions: 1. The resume code runs in a PM notifier which is invoked after user space has been thawed, so it can run concurrently with user space which can trigger a thermal zone device removal. If that happens, the thermal zone resume code may use a stale pointer to the next list element and crash, because it does not hold thermal_list_lock while walking thermal_tz_list. 2. The thermal zone resume code calls thermal_zone_device_init() outside the zone lock, so user space or an update triggered by the platform firmware may see an inconsistent state of a thermal zone leading to unexpected behavior. 3. Clearing the in_suspend global variable in thermal_pm_notify() allows __thermal_zone_device_update() to continue for all thermal zones and it may as well run before the thermal_tz_list walk (or at any point during the list walk for that matter) and attempt to operate on a thermal zone that has not been resumed yet. It may also race destructively with thermal_zone_device_init(). To address these issues, add thermal_list_lock locking to thermal_pm_notify(), especially arount the thermal_tz_list, make it call thermal_zone_device_init() back-to-back with __thermal_zone_device_update() under the zone lock and replace in_suspend with per-zone bool "suspend" indicators set and unset under the given zone's lock.

2023-12-28firmware: coreboot: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-12-27igc: Check VLAN EtherType maskKurt Kanzenbach
Currently the driver accepts VLAN EtherType steering rules regardless of the configured mask. And things might fail silently or with confusing error messages to the user. The VLAN EtherType can only be matched by full mask. Therefore, add a check for that. For instance the following rule is invalid, but the driver accepts it and ignores the user specified mask: |root@host:~# ethtool -N enp3s0 flow-type ether vlan-etype 0x8100 \ | m 0x00ff action 0 |Added rule with ID 63 |root@host:~# ethtool --show-ntuple enp3s0 |4 RX rings available |Total 1 rules | |Filter: 63 | Flow Type: Raw Ethernet | Src MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF | Dest MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF | Ethertype: 0x0 mask: 0xFFFF | VLAN EtherType: 0x8100 mask: 0x0 | VLAN: 0x0 mask: 0xffff | User-defined: 0x0 mask: 0xffffffffffffffff | Action: Direct to queue 0 After: |root@host:~# ethtool -N enp3s0 flow-type ether vlan-etype 0x8100 \ | m 0x00ff action 0 |rmgr: Cannot insert RX class rule: Operation not supported Fixes: 2b477d057e33 ("igc: Integrate flex filter into ethtool ops") Suggested-by: Suman Ghosh <sumang@marvell.com> Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Acked-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2023-12-27igc: Check VLAN TCI maskKurt Kanzenbach
Currently the driver accepts VLAN TCI steering rules regardless of the configured mask. And things might fail silently or with confusing error messages to the user. There are two ways to handle the VLAN TCI mask: 1. Match on the PCP field using a VLAN prio filter 2. Match on complete TCI field using a flex filter Therefore, add checks and code for that. For instance the following rule is invalid and will be converted into a VLAN prio rule which is not correct: |root@host:~# ethtool -N enp3s0 flow-type ether vlan 0x0001 m 0xf000 \ | action 1 |Added rule with ID 61 |root@host:~# ethtool --show-ntuple enp3s0 |4 RX rings available |Total 1 rules | |Filter: 61 | Flow Type: Raw Ethernet | Src MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF | Dest MAC addr: 00:00:00:00:00:00 mask: FF:FF:FF:FF:FF:FF | Ethertype: 0x0 mask: 0xFFFF | VLAN EtherType: 0x0 mask: 0xffff | VLAN: 0x1 mask: 0x1fff | User-defined: 0x0 mask: 0xffffffffffffffff | Action: Direct to queue 1 After: |root@host:~# ethtool -N enp3s0 flow-type ether vlan 0x0001 m 0xf000 \ | action 1 |rmgr: Cannot insert RX class rule: Operation not supported Fixes: 7991487ecb2d ("igc: Allow for Flex Filters to be installed") Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de> Acked-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2023-12-27ice: dpll: fix phase offset valueArkadiusz Kubalewski
Stop dividing the phase_offset value received from firmware. This fault is present since the initial implementation. The phase_offset value received from firmware is in 0.01ps resolution. Dpll subsystem is using the value in 0.001ps, raw value is adjusted before providing it to the user. The user can observe the value of phase offset with response to `pin-get` netlink message of dpll subsystem for an active pin: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \ --do pin-get --json '{"id":2}' Where example of correct response would be: {'board-label': 'C827_0-RCLKA', 'capabilities': 6, 'clock-id': 4658613174691613800, 'frequency': 1953125, 'id': 2, 'module-name': 'ice', 'parent-device': [{'direction': 'input', 'parent-id': 6, 'phase-offset': -216839550, 'prio': 9, 'state': 'connected'}, {'direction': 'input', 'parent-id': 7, 'phase-offset': -42930, 'prio': 8, 'state': 'connected'}], 'phase-adjust': 0, 'phase-adjust-max': 16723, 'phase-adjust-min': -16723, 'type': 'mux'} Provided phase-offset value (-42930) shall be divided by the user with DPLL_PHASE_OFFSET_DIVIDER to get actual value of -42.930 ps.

2023-12-27gfs2: Fix freeze consistency check in log_write_headerAndreas Gruenbacher
Functions gfs2_freeze_super() and gfs2_thaw_super() are using the SDF_FROZEN flag to indicate when the filesystem is frozen, synchronized by sd_freeze_mutex. However, this doesn't prevent writes from happening between the point of calling thaw_super() and the point where the SDF_FROZEN flag is cleared, so the following assert can trigger in log_write_header(): gfs2_assert_withdraw(sdp, !test_bit(SDF_FROZEN, &sdp->sd_flags)); Fix that by checking for sb->s_writers.frozen != SB_FREEZE_COMPLETE in log_write_header() instead. To make sure that the filesystem-specific part of freezing happens before sb->s_writers.frozen is set to SB_FREEZE_COMPLETE, move that code from gfs2_freeze_locally() into gfs2_freeze_fs() and hook that up to the .freeze_fs operation.

2023-12-27gfs2: Refcounting fix in gfs2_thaw_superAndreas Gruenbacher
It turns out that the .freeze_super and .thaw_super operations require the filesystem to manage the superblock refcount itself. We are using the freeze_super() and thaw_super() helpers to mostly take care of that for us, but this means that the superblock may no longer be around by when thaw_super() returns, and gfs2_thaw_super() will then access freed memory. Take an extra superblock reference in gfs2_thaw_super() to fix that. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
