2024-09-03wifi: iwlwifi: mvm: properly set the rates in link cmdMiri Korenblit
When a channel ctx is assigned to a link, we set the LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now valid. But then we always take the rates of 2.4 GHz regardless of actual used band. This is because we are getting the band from bss_conf->chanctx_conf, but this is assigned only after drv_assign_vif_chanctx returns, so we take the bands of 2.4 GHz. Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead, as this has already assigned in this point.

2024-09-03wifi: iwlwifi: mvm: tell the firmware about CSA with mode=1Emmanuel Grumbach
When we de-activate a link because it started a CSA with mode=1, we want to tell the firmware it can no longer transmit any frame for that link. The firmware will do that on its own if the CSA indication (beacon / action frame) was received on that same link, but with MLO, things got more complex and the firmware can't track cross link CSA. Tell the firmware if we de-activate a link because of CSA with mode=1 to prevent it from transmitting, even if it is only an NDP PM=1 frame that is part of the de-activation flow.

2024-09-03Merge branch 'netdev_features-start-cleaning-netdev_features_t-up'Paolo Abeni
Alexander Lobakin says: ==================== netdev_features: start cleaning netdev_features_t up NETDEV_FEATURE_COUNT is currently 64, which means we can't add any new features as netdev_features_t is u64. As per several discussions, instead of converting netdev_features_t to a bitmap, which would mean A LOT of changes, we can try cleaning up netdev feature bits. There's a bunch of bits which don't really mean features, rather device attributes/properties that can't be changed via Ethtool in any of the drivers. Such attributes can be moved to netdev private flags without losing any functionality. Start converting some read-only netdev features to private flags from the ones that are most obvious, like lockless Tx, inability to change network namespace etc. I was able to reduce NETDEV_FEATURE_COUNT from 64 to 60, which mean 4 free slots for new features. There are obviously more read-only features to convert, such as highDMA, "challenged VLAN", HSR (4 bits) - this will be done in subsequent series. Please note that currently netdev features are not uAPI/ABI by any means. Ethtool passes their names and bits to the userspace separately and there are no hardcoded names/bits in the userspace, so that new Ethtool could work on older kernels and vice versa. This, however, isn't true for Ethtools < 3.4. I haven't changed the bit positions of the already existing features and instead replaced the freed bits with stubs. But it's anyway theoretically possible that Ethtools older than 2011 will break. I hope no currently supported distros supply such an ancient version. Shell scripts also most likely won't break since the removed bits were always read-only, meaning nobody would try touching them from a script. ==================== Link: https://patch.msgid.link/20240829123340.789395-1-aleksander.lobakin@intel.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2024-09-03netdev_features: convert NETIF_F_FCOE_MTU to dev->fcoe_mtuAlexander Lobakin

2024-09-03netdevice: convert private flags > BIT(31) to bitfieldsAlexander Lobakin
Make dev->priv_flags `u32` back and define bits higher than 31 as bitfield booleans as per Jakub's suggestion. This simplifies code which accesses these bits with no optimization loss (testb both before/after), allows to not extend &netdev_priv_flags each time, but also scales better as bits > 63 in the future would only add a new u64 to the structure with no complications, comparing to that extending ::priv_flags would require converting it to a bitmap. Note that I picked `unsigned long :1` to not lose any potential optimizations comparing to `bool :1` etc. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Alexander Lobakin <aleksander.lobakin@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2024-09-03x86/cpu/intel: Replace PAT erratum model/family magic numbers with symbolic ↵Dave Hansen
IFM references There's an erratum that prevents the PAT from working correctly: https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/pentium-dual-core-specification-update.pdf # Document 316515 Version 010 The kernel currently disables PAT support on those CPUs, but it does it with some magic numbers. Replace the magic numbers with the new "IFM" macros. Make the check refer to the last affected CPU (INTEL_CORE_YONAH) rather than the first fixed one. This makes it easier to find the documentation of the erratum since Intel documents where it is broken and not where it is fixed. I don't think the Pentium Pro (or Pentium II) is actually affected. But the old check included them, so it can't hurt to keep doing the same. I'm also not completely sure about the "Pentium M" CPUs (models 0x9 and 0xd). But, again, they were included in in the old checks and were close Pentium III derivatives, so are likely affected. While we're at it, revise the comment referring to the erratum name and making sure it is a quote of the language from the actual errata doc. That should make it easier to find in the future when the URL inevitably changes. Why bother with this in the first place? It actually gets rid of one of the very few remaining direct references to c->x86{,_model}. No change in functionality intended.

2024-09-03netfilter: nft_counter: Use u64_stats_t for statistic.Sebastian Andrzej Siewior
The nft_counter uses two s64 counters for statistics. Those two are protected by a seqcount to ensure that the 64bit variable is always properly seen during updates even on 32bit architectures where the store is performed by two writes. A side effect is that the two counter (bytes and packet) are written and read together in the same window. This can be replaced with u64_stats_t. write_seqcount_begin()/ end() is replaced with u64_stats_update_begin()/ end() and behaves the same way as with seqcount_t on 32bit architectures. Additionally there is a preempt_disable on PREEMPT_RT to ensure that a reader does not preempt a writer. On 64bit architectures the macros are removed and the reads happen without any retries. This also means that the reader can observe one counter (bytes) from before the update and the other counter (packets) but that is okay since there is no requirement to have both counter from the same update window. Convert the statistic to u64_stats_t. There is one optimisation: nft_counter_do_init() and nft_counter_clone() allocate a new per-CPU counter and assign a value to it. During this assignment preemption is disabled which is not needed because the counter is not yet exposed to the system so there can not be another writer or reader. Therefore disabling preemption is omitted and raw_cpu_ptr() is used to obtain a pointer to a counter for the assignment.

In ucsi_check_connector_capability() the version was assumed to be 2.0, and in ucsi_register_partner() the field is accessed completely unconditionally. Fixing the version in ucsi_check_connector_capability(), and replacing the unconditional pd_revision assignment with a direct call to ucsi_check_connector_capability() in ucsi_register_port(). After this the revision is also checked only if there is a PD contract.

2024-09-03usb: dwc3: core: update LC timer as per USB Spec V3.2Faisal Hassan
This fix addresses STAR 9001285599, which only affects DWC_usb3 version 3.20a. The timer value for PM_LC_TIMER in DWC_usb3 3.20a for the Link ECN changes is incorrect. If the PM TIMER ECN is enabled via GUCTL2[19], the link compliance test (TD7.21) may fail. If the ECN is not enabled (GUCTL2[19] = 0), the controller will use the old timer value (5us), which is still acceptable for the link compliance test. Therefore, clear GUCTL2[19] to pass the USB link compliance test: TD 7.21.

2024-09-03usb: dwc3: Avoid waking up gadget during startxferPrashanth K
When operating in High-Speed, it is observed that DSTS[USBLNKST] doesn't update link state immediately after receiving the wakeup interrupt. Since wakeup event handler calls the resume callbacks, there is a chance that function drivers can perform an ep queue, which in turn tries to perform remote wakeup from send_gadget_ep_cmd(STARTXFER). This happens because DSTS[[21:18] wasn't updated to U0 yet, it's observed that the latency of DSTS can be in order of milli-seconds. Hence avoid calling gadget_wakeup during startxfer to prevent unnecessarily issuing remote wakeup to host.

Currently there is no way to apply quirk on device only if certain panel model is installed. This patch implements such mechanism by adding new quirk type intel_dpcd_quirk which contains also sink_oui and sink_device_id fields and using also them to figure out if applying quirk is needed. New intel_init_dpcd_quirks is added and called after drm_dp_read_desc with proper sink device identity read from dpcdc. v3: - !mem_is_zero fixed to mem_is_zero v2: - instead of using struct intel_quirk add new struct intel_dpcd_quirk Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240902064241.1020965-2-jouni.hogander@intel.com (cherry picked from commit b3b91369908ac63be6f64905448b8ba5cd151875) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

2024-09-02btrfs: zoned: handle broken write pointer on zonesNaohiro Aota
Btrfs rejects to mount a FS if it finds a block group with a broken write pointer (e.g, unequal write pointers on two zones of RAID1 block group). Since such case can happen easily with a power-loss or crash of a system, we need to handle the case more gently. Handle such block group by making it unallocatable, so that there will be no writes into it. That can be done by setting the allocation pointer at the end of allocating region (= block_group->zone_capacity). Then, existing code handle zone_unusable properly. Having proper zone_capacity is necessary for the change. So, set it as fast as possible. We cannot handle RAID0 and RAID10 case like this. But, they are anyway unable to read because of a missing stripe.

The 32-bit arm build system will complain: tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type 75 | struct perf_sample sample; However, arm64 build system doesn't complain this. The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in tools/perf/arch/arm64/Makefile, but arm arch doesn't define this. This will lead to kvm-stat.h include other header files on arm64 build system, especially "util/sample.h" for util/python.c.

2024-09-02perf lock contention: Fix spinlock and rwlock accountingNamhyung Kim
The spinlock and rwlock use a single-element per-cpu array to track current locks due to performance reason. But this means the key is always available and it cannot simply account lock stats in the array because some of them are invalid. In fact, the contention_end() program in the BPF invalidates the entry by setting the 'lock' value to 0 instead of deleting the entry for the hashmap. So it should skip entries with the lock value of 0 in the account_end_timestamp(). Otherwise, it'd have spurious high contention on an idle machine: $ sudo perf lock con -ab -Y spinlock sleep 3 contended total wait max wait avg wait type caller 8 4.72 s 1.84 s 590.46 ms spinlock rcu_core+0xc7 8 1.87 s 1.87 s 233.48 ms spinlock process_one_work+0x1b5 2 1.87 s 1.87 s 933.92 ms spinlock worker_thread+0x1a2 3 1.81 s 1.81 s 603.93 ms spinlock tmigr_update_events+0x13c 2 1.72 s 1.72 s 861.98 ms spinlock tick_do_update_jiffies64+0x25 6 42.48 us 13.02 us 7.08 us spinlock futex_q_lock+0x2a 1 13.03 us 13.03 us 13.03 us spinlock futex_wake+0xce 1 11.61 us 11.61 us 11.61 us spinlock rcu_core+0xc7 I don't believe it has contention on a spinlock longer than 1 second.
