git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems" * tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (120 commits) device property: make device_property functions take const device * driver core: update comments in device_rename() driver core: Don't require dynamic_debug for initcall_debug probe timing firmware_loader: rework crypto dependencies firmware_loader: Strip off \n from customized path zram: fix up permission for the hot_add sysfs file cacheinfo: Add use_arch[|_cache]_info field/function arch_topology: Remove early cacheinfo error message if -ENOENT cacheinfo: Check cache properties are present in DT cacheinfo: Check sib_leaf in cache_leaves_are_shared() cacheinfo: Allow early level detection when DT/ACPI info is missing/broken cacheinfo: Add arm64 early level initializer implementation cacheinfo: Add arch specific early level initializer tty: make tty_class a static const structure driver core: class: remove struct class_interface * from callbacks driver core: class: mark the struct class in struct class_interface constant driver core: class: make class_register() take a const * driver core: class: mark class_release() as taking a const * driver core: remove incorrect comment for device_create* MIPS: vpe-cmp: remove module owner pointer from struct class usage. ...

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "A fairly standard release for SPI with the exception of a change to the API for specifying chip selects done in preparation for supporting devices with more than one chip select, this required some mechanical changes throughout the tree which have been cooking in -next happily for a while. There's also a new API to allow us to support TPM chips on half duplex controllers. Summary: - Refactoring in preparation for supporting multiple chip selects for a single device, needed by some flash devices, which required a change in the SPI device API visible throughout the tree - Support for hardware assisted interaction with SPI TPMs on half duplex controllers, implemented on nVidia Tedra210 QuadSPI - Optimisation for large transfers on fsl-cpm devices - Cleanups around device property use which fix some sisues with fwnode - Use of both void remove() and devm_platform_.*ioremap_resource() - Support for AMD Pensando Elba, Amlogic A1, Cadence device mode, Intel MetorLake-S and StarFive J7110 QuadSPI" * tag 'spi-v6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (185 commits) spi: bcm63xx: use macro DEFINE_SIMPLE_DEV_PM_OPS spi: tegra210-quad: Enable TPM wait polling spi: Add TPM HW flow flag spi: bcm63xx: remove PM_SLEEP based conditional compilation spi: cadence-quadspi: use macro DEFINE_SIMPLE_DEV_PM_OPS spi: spi-cadence: Add support for Slave mode spi: spi-cadence: Switch to spi_controller structure spi: cadence-quadspi: fix suspend-resume implementations spi: dw: Add support for AMD Pensando Elba SoC spi: dw: Add AMD Pensando Elba SoC SPI Controller spi: cadence-quadspi: Disable the SPI before reconfiguring spi: cadence-quadspi: Update the read timeout based on the length spi: spi-loopback-test: Add module param for iteration length spi: add support for Amlogic A1 SPI Flash Controller dt-bindings: spi: add Amlogic A1 SPI controller spi: fsl-spi: No need to check transfer length versus word size spi: fsl-spi: Change mspi_apply_cpu_mode_quirks() to void spi: fsl-cpm: Use 16 bit mode for large transfers with even size spi: fsl-spi: Re-organise transfer bits_per_word adaptation spi: fsl-spi: Fix CPM/QE mode Litte Endian ...

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the default value allows for better BIG TCP performances - Reduce compound page head access for zero-copy data transfers - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible - Threaded NAPI improvements, adding defer skb free support and unneeded softirq avoidance - Address dst_entry reference count scalability issues, via false sharing avoidance and optimize refcount tracking - Add lockless accesses annotation to sk_err[_soft] - Optimize again the skb struct layout - Extends the skb drop reasons to make it usable by multiple subsystems - Better const qualifier awareness for socket casts BPF: - Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses - Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward - Add more precise memory usage reporting for all BPF map types - Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params - Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton - Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps - Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps - Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree - Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them - Add ARM32 USDT support to libbpf - Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations Protocols: - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value indicates the provenance of the IP address - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition - Add the handshake upcall mechanism, allowing the user-space to implement generic TLS handshake on kernel's behalf - Bridge: support per-{Port, VLAN} neighbor suppression, increasing resilience to nodes failures - SCTP: add support for Fair Capacity and Weighted Fair Queueing schedulers - MPTCP: delay first subflow allocation up to its first usage. This will allow for later better LSM interaction - xfrm: Remove inner/outer modes from input/output path. These are not needed anymore - WiFi: - reduced neighbor report (RNR) handling for AP mode - HW timestamping support - support for randomized auth/deauth TA for PASN privacy - per-link debugfs for multi-link - TC offload support for mac80211 drivers - mac80211 mesh fast-xmit and fast-rx support - enable Wi-Fi 7 (EHT) mesh support Netfilter: - Add nf_tables 'brouting' support, to force a packet to be routed instead of being bridged - Update bridge netfilter and ovs conntrack helpers to handle IPv6 Jumbo packets properly, i.e. fetch the packet length from hop-by-hop extension header. This is needed for BIT TCP support - The iptables 32bit compat interface isn't compiled in by default anymore - Move ip(6)tables builtin icmp matches to the udptcp one. This has the advantage that icmp/icmpv6 match doesn't load the iptables/ip6tables modules anymore when iptables-nft is used - Extended netlink error report for netdevice in flowtables and netdev/chains. Allow for incrementally add/delete devices to netdev basechain. Allow to create netdev chain without device Driver API: - Remove redundant Device Control Error Reporting Enable, as PCI core has already error reporting enabled at enumeration time - Move Multicast DB netlink handlers to core, allowing devices other then bridge to use them - Allow the page_pool to directly recycle the pages from safely localized NAPI - Implement lockless TX queue stop/wake combo macros, allowing for further code de-duplication and sanitization - Add YNL support for user headers and struct attrs - Add partial YNL specification for devlink - Add partial YNL specification for ethtool - Add tc-mqprio and tc-taprio support for preemptible traffic classes - Add tx push buf len param to ethtool, specifies the maximum number of bytes of a transmitted packet a driver can push directly to the underlying device - Add basic LED support for switch/phy - Add NAPI documentation, stop relaying on external links - Convert dsa_master_ioctl() to netdev notifier.

2023-04-20wifi: ath9k: Don't mark channelmap stack variable read-only in ↵Toke Høiland-Jørgensen
ath9k_mci_update_wlan_channels() This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa. Turns out the channelmap variable is not actually read-only, it's modified through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function, so making it read-only causes page faults when that code is hit.

The goal of writing 0x6954341e / 0x6955341e to REG_OFDM0_XA_AGC_CORE1 appears to be setting the initial gain, which is stored in bits 0..6. Bits 7..31 are the same as what the phy init tables write. Modify only bits 0..6 so that we don't have to care about the values of the others. This way we don't have to add another "else if" for the RTL8192FU. Why we need to change the initial gain from the default 0x20 to 0x1e? Not sure. Some of the vendor drivers change it to 0x1e before scanning and then restore it to the original value after.

2023-04-20wifi: rtw88: rtw8821c: Fix rfe_option field widthSascha Hauer
On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the vendor driver suggests that the field width of rfe_option is 5 bit, so rfe_option should be masked with 0x1f. Without this the rfe_option comparisons with 2 further down the driver evaluate as false when they should really evaluate as true. The effect is that 2G channels do not work. rfe_option is also used as an array index into rtw8821c_rfe_defs[]. rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support, likely because rfe_option reads as 0x22. As this now becomes 0x2, rtw8821c_rfe_defs[34] is no longer used and can be removed. Note that this might not be the whole truth. In the vendor driver there are indeed places where the unmasked rfe_option value is used. However, the driver has several places where rfe_option is tested with the pattern if (rfe_option == 2 || rfe_option == 0x22) or if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5) has no influence on the code path taken. We therefore mask BIT(5) out from rfe_option entirely until this assumption is proved wrong by some chip variant we do not know yet.

2023-04-20wifi: iwlwifi: mvm: fix MIC removal confusionJohannes Berg
The RADA/firmware collaborate on MIC stripping in the following way: - the firmware fills the IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK value for how many words need to be removed at the end of the frame, CRC and, if decryption was done, MIC - if the RADA is active, it will - remove that much from the end of the frame - zero the value in IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK As a consequence, the only thing the driver should need to do is to - unconditionally tell mac80211 that the MIC was removed if decryption was already done - remove as much as IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK says at the end of the frame, since either RADA did it and then the value is 0, or RADA was disabled and then the value is whatever should be removed to strip both CRC & MIC However, all this code was historically grown and getting a bit confused. Originally, we were indicating that the MIC was not stripped, which is the version of the code upstreamed in commit 780e87c29e77 ("iwlwifi: mvm: add 9000 series RX processing") which indicated RX_FLAG_DECRYPTED in iwl_mvm_rx_crypto(). We later had a commit to change that to also indicate that the MIC was stripped, adding RX_FLAG_MIC_STRIPPED. However, this was then "fixed" later to only do that conditionally on RADA being enabled, since otherwise RADA didn't strip the MIC bytes yet. At the time, we were also always including the FCS if the RADA was not enabled, so that was still broken wrt. the FCS if the RADA isn't enabled - but that's a pretty rare case. Notably though, it does happen for management frames, where we do need to remove the MIC and CRC but the RADA is disabled. Later, in commit 40a0b38d7a7f ("iwlwifi: mvm: Fix calculation of frame length"), we changed this again, upstream this was just a single commit, but internally it was split into first the correct commit and then an additional fix that reduced the number of bytes that are removed by crypt_len. Note that this is clearly wrong since crypt_len indicates the length of the PN header (always 8), not the length of the MIC (8 or 16 depending on algorithm). However, this additional fix mostly canceled the other bugs, apart from the confusion about the size of the MIC. To fix this correctly, remove all those additional workarounds. We really should always indicate to mac80211 the MIC was stripped (it cannot use it anyway if decryption was already done), and also always actually remove it and the CRC regardless of the RADA being enabled or not. That's simple though, the value indicated in the metadata is zeroed by the RADA if it's enabled and used the value, so there's no need to check if it's enabled or not. Notably then, this fixes the MIC size confusion, letting us receive GCMP-256 encrypted management frames correctly that would otherwise be reported to mac80211 8 bytes too short since the RADA is turned off for them, crypt_len is 8, but the MIC size is 16, so when we do the adjustment based on IWL_RX_MPDU_MFLG1_MIC_CRC_LEN_MASK (which indicates 20 bytes to remove) we remove 12 bytes but indicate then to mac80211 the MIC is still present, so mac80211 again removes the MIC of 16 bytes, for an overall removal of 28 rather than 20 bytes.

ath9k_mci_update_wlan_channels() This partially reverts commit e161d4b60ae3a5356e07202e0bfedb5fad82c6aa. Turns out the channelmap variable is not actually read-only, it's modified through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function, so making it read-only causes page faults when that code is hit.

2023-04-19wifi: ath11k: Fix SKB corruption in REO destination ringNagarajan Maran
While running traffics for a long time, randomly an RX descriptor filled with value "0" from REO destination ring is received. This descriptor which is invalid causes the wrong SKB (SKB stored in the IDR lookup with buffer id "0") to be fetched which in turn causes SKB memory corruption issue and the same leads to crash after some time. Changed the start id for idr allocation to "1" and the buffer id "0" is reserved for error validation. Introduced Sanity check to validate the descriptor, before processing the SKB. Crash Signature : Unable to handle kernel paging request at virtual address 3f004900 PC points to "b15_dma_inv_range+0x30/0x50" LR points to "dma_cache_maint_page+0x8c/0x128".

2023-04-19wifi: ath11k: fix double free of peer rx_tid during reo cmd failureHarshitha Prem
Peer rx_tid is locally copied thrice during peer_rx_tid_cleanup to send REO_CMD_UPDATE_RX_QUEUE followed by REO_CMD_FLUSH_CACHE to flush all aged REO descriptors from HW cache. When sending REO_CMD_FLUSH_CACHE fails, we do dma unmap of already mapped rx_tid->vaddr and free it. This is not checked during reo_cmd_list_cleanup() and dp_reo_cmd_free() before trying to free and unmap again. Fix this by setting rx_tid->vaddr NULL in rx tid delete and also wherever freeing it to check in reo_cmd_list_cleanup() and reo_cmd_free() before trying to free again.
