This is part of an effort [1] to assign a section in MAINTAINERS to header files that relate to Networking. In this case the files with "net" in their name. [1] https://lore.kernel.org/netdev/20240821-net-mnt-v2-0-59a5af38e69d@kernel.org/ It seems that net-cw1200.h is part of the CW1200 WLAN driver and this it is appropriate to add it to the section for that driver.

ath.git patches for v6.11-rc7 We have three patch which address two issues in the ath11k driver which should be addressed for 6.11-rc7: One patch fixes a NULL pointer dereference while parsing transmit power envelope (TPE) information, and the other two patches revert the hibernation support since it is interfering with suspend on some platforms. Note the cause of the suspend wakeups is still being investigated, and it is hoped this can be addressed and hibernation support can be restored in the near future.

When the firmware crashes, we first told the op_mode and only then, changed the transport's state. This is a problem if the op_mode's nic_error() handler needs to send a host command: it'll see that the transport's state still reflects that the firmware is alive. Today, this has no consequences since we set the STATUS_FW_ERROR bit and that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording looks at this bit to know not to send a host command for example. To fix the hibernation, we needed to reset the firmware without having an error and checking STATUS_FW_ERROR to see whether the firmware is alive will no longer hold, so this change is necessary as well. Change the flow a bit. Change trans->state before calling the op_mode's nic_error() method and check trans->state instead of STATUS_FW_ERROR. This will keep the current behavior of iwl_fw_dbg_stop_restart_recording upon firmware error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not alive.

There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was recently converted from just a message), that can be hit if we wait for TX queues to become empty after firmware died. Clearly, we can't expect anything from the firmware after it's declared dead. Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could be a good idea to stop the flow earlier, the flush functions do some maintenance work that is not related to the firmware, so keep that part of the code running even when the firmware is not running.

Fast resume is a feature that was recently introduced to speed up the resume time. It basically keeps the firmware alive while the system is suspended and that avoids starting again the whole device. This flow can't work for hibernation, since when the system boots, before the frozen image is loaded, the kernel may touch the device. As a result, we can't assume the device is in the exact same state as before the hibernation. Detect that we are resuming from hibernation through the PCI device and forbid the fast resume flow. We also need to shut down the device cleanly when that happens. In addition, in case the device is power gated during S3, we won't be able to keep the device alive. Detect this situation with BE200 at least with the help of the CSR_FUNC_SCRATCH register and reset the device upon resume if it was power gated during S3.

Commit 39dc8b8e ("wifi: mac80211: pass parsed TPE data to drivers") breaks ath11k, leading to kernel crash: BUG: kernel NULL pointer dereference, address: 0000000000000018 RIP: 0010:ath11k_mac_get_eirp_power.isra.0+0x5b/0x80 [ath11k] Call Trace: <TASK> ath11k_mac_fill_reg_tpc_info+0x3d6/0x800 [ath11k] ath11k_mac_vdev_start_restart+0x412/0x4d0 [ath11k] ath11k_mac_op_sta_state+0x7bc/0xbb0 [ath11k] drv_sta_state+0xf1/0x5f0 [mac80211] sta_info_insert_rcu+0x28d/0x530 [mac80211] sta_info_insert+0xf/0x20 [mac80211] ieee80211_prep_connection+0x3b4/0x4c0 [mac80211] ieee80211_mgd_auth+0x363/0x600 [mac80211] The issue scenario is, AP advertises power spectral density (PSD) values in its transmit power envelope (TPE) IE and supports 160 MHz bandwidth in 6 GHz. When connecting to this AP, in ath11k_mac_parse_tx_pwr_env(), the local variable psd is true and then reg_tpc_info.num_pwr_levels is set to 8 due to 160 MHz bandwidth. Note here ath11k fails to set reg_tpc_info.is_psd_power as TRUE due to above commit. Then in ath11k_mac_fill_reg_tpc_info(), for each of the 8 power levels, for a PSD channel, ath11k_mac_get_psd_channel() is expected to be called to get required information. However due to invalid reg_tpc_info.is_psd_power, it is ath11k_mac_get_eirp_power() that gets called and passed with pwr_lvl_idx as one of the arguments. Note this function implicitly requires pwr_lvl_idx to be no more than 3. So when pwr_lvl_idx is larger than that ath11k_mac_get_seg_freq() returns invalid center frequency, with which as the input ieee80211_get_channel() returns NULL, then kernel crashes due to NULL pointer dereference. Fix it by setting reg_tpc_info.is_psd_power properly.

The code to lookup the scatter gather table entry assumed that it was possible to use sg_virt() in order to lookup the DMA address in a mapped scatter gather table. However, this assumption is incorrect as the DMA mapping code may merge multiple entries into one. In that case, the DMA address space may have e.g. two consecutive pages which is correctly represented by the scatter gather list entry, however the virtual addresses for these two pages may differ and the relationship cannot be resolved anymore. Avoid this problem entirely by working with the offset into the mapped area instead of using virtual addresses. With that we only use the DMA length and DMA address from the scatter gather list entries. The underlying DMA/IOMMU code is therefore free to merge two entries into one even if the virtual addresses space for the area is not continuous.

In transmit path, it is likely that the iova is not aligned to PCIe TLP max payload size, which is 128 for WCN7850. Normally in such cases hardware is expected to split the packet into several parts in a manner such that they, other than the first one, have aligned iova. However due to hardware limitations, WCN7850 does not behave like that properly with some specific unaligned iova in transmit path. This easily results in target hang in a KPI transmit test: packet send/receive failure, WMI command send timeout etc. Also fatal error seen in PCIe level: ... Capabilities: ... ... DevSta: ... FatalErr+ ... ... ... Work around this by manually moving/reallocating payload buffer such that we can map it to a 128 bytes aligned iova. The moving requires sufficient head room or tail room in skb: for the former we can do ourselves a favor by asking some extra bytes when registering with mac80211, while for the latter we can do nothing. Moving/reallocating buffer consumes additional CPU cycles, but the good news is that an aligned iova increases PCIe efficiency. In my tests on some X86 platforms the KPI results are almost consistent. Since this is seen only with WCN7850, add a new hardware parameter to differentiate from others.

Pull x86 fixes from Thomas Gleixner: - Prevent a deadlock on cpu_hotplug_lock in the aperf/mperf driver. A recent change in the ACPI code which consolidated code pathes moved the invocation of init_freq_invariance_cppc() to be moved to a CPU hotplug handler. The first invocation on AMD CPUs ends up enabling a static branch which dead locks because the static branch enable tries to acquire cpu_hotplug_lock but that lock is already held write by the hotplug machinery. Use static_branch_enable_cpuslocked() instead and take the hotplug lock read for the Intel code path which is invoked from the architecture code outside of the CPU hotplug operations. - Fix the number of reserved bits in the sev_config structure bit field so that the bitfield does not exceed 64 bit. - Add missing Zen5 model numbers - Fix the alignment assumptions of pti_clone_pgtable() and clone_entry_text() on 32-bit: The code assumes PMD aligned code sections, but on 32-bit the kernel entry text is not PMD aligned. So depending on the code size and location, which is configuration and compiler dependent, entry text can cross a PMD boundary. As the start is not PMD aligned adding PMD size to the start address is larger than the end address which results in partially mapped entry code for user space. That causes endless recursion on the first entry from userspace (usually #PF). Cure this by aligning the start address in the addition so it ends up at the next PMD start address. clone_entry_text() enforces PMD mapping, but on 32-bit the tail might eventually be PTE mapped, which causes a map fail because the PMD for the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for the clone() invocation which resolves to PTE on 32-bit and PMD on 64-bit. - Zero the 8-byte case for get_user() on range check failure on 32-bit The recend consolidation of the 8-byte get_user() case broke the zeroing in the failure case again. Establish it by clearing ECX before the range check and not afterwards as that obvioulsy can't be reached when the range check fails * tag 'x86-urgent-2024-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/uaccess: Zero the 8-byte get_range case on failure on 32-bit x86/mm: Fix pti_clone_entry_text() for i386 x86/mm: Fix pti_clone_pgtable() alignment assumption x86/setup: Parse the builtin command line before merging x86/CPU/AMD: Add models 0x60-0x6f to the Zen5 range x86/sev: Fix __reserved field in sev_config x86/aperfmperf: Fix deadlock on cpu_hotplug_lock

Pull locking fixes from Thomas Gleixner: "Two fixes for locking and jump labels: - Ensure that the atomic_cmpxchg() conditions are correct and evaluating to true on any non-zero value except 1. The missing check of the return value leads to inconsisted state of the jump label counter. - Add a missing type conversion in the paravirt spinlock code which makes loongson build again" * tag 'locking-urgent-2024-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: jump_label: Fix the fix, brown paper bags galore locking/pvqspinlock: Correct the type of "old" variable in pv_kick_node() -

Commit 04f08ef2 ("arm/arm64: dts: arm: Use generic clock and regulator nodenames") renamed nodes and created 2 "clock-24000000" nodes (at different paths). The kernel can't handle these duplicate names even though they are at different paths. Fix this by renaming one of the nodes to "clock-pclk". This name is aligned with other Arm boards (those didn't have a known frequency to use in the node name). Fixes: 04f08ef2 ("arm/arm64: dts: arm: Use generic clock and regulator nodenames") Reported-by:

The runtime constants linker script depended on documented linker behavior [1]: "If an output section’s name is the same as the input section’s name and is representable as a C identifier, then the linker will automatically PROVIDE two symbols: __start_SECNAME and __stop_SECNAME, where SECNAME is the name of the section. These indicate the start address and end address of the output section respectively" to just automatically define the symbol names for the bounds of the runtime constant arrays. It turns out that this isn't actually something we can rely on, with old linkers not generating these automatic symbols. It looks to have been introduced in binutils-2.29 back in 2017, and we still support building with versions all the way back to binutils-2.25 (from 2015). And yes, Oleg actually seems to be using such ancient versions of binutils. So instead of depending on the implicit symbols from "section names match and are representable C identifiers", just do this all manually. It's not like it causes us any extra pain, we already have to do that for all the other sections that we use that often have special characters in them. Reported-and-tested-by:
