Pull networking fixes from Jakub Kicinski: "Including fixes from IPSec, netfilter and Bluetooth.

Pull driver core and debugfs updates from Greg KH: "Here is the big set of driver core and debugfs updates for 6.14-rc1. Included in here is a bunch of driver core, PCI, OF, and platform rust bindings (all acked by the different subsystem maintainers), hence the merge conflict with the rust tree, and some driver core api updates to mark things as const, which will also require some fixups due to new stuff coming in through other trees in this merge window. There are also a bunch of debugfs updates from Al, and there is at least one user that does have a regression with these, but Al is working on tracking down the fix for it. In my use (and everyone else's linux-next use), it does not seem like a big issue at the moment. Here's a short list of the things in here: - driver core rust bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do. - misc device rust bindings and a sample driver to show how to use them - debugfs cleanups in the fs as well as the users of the fs api for places where drivers got it wrong or were unnecessarily doing things in complex ways. - driver core const work, making more of the api take const * for different parameters to make the rust bindings easier overall. - other small fixes and updates All of these have been in linux-next with all of the aforementioned merge conflicts, and the one debugfs issue, which looks to be resolved "soon"" * tag 'driver-core-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (95 commits) rust: device: Use as_char_ptr() to avoid explicit cast rust: device: Replace CString with CStr in property_present() devcoredump: Constify 'struct bin_attribute' devcoredump: Define 'struct bin_attribute' through macro rust: device: Add property_present() saner replacement for debugfs_rename() orangefs-debugfs: don't mess with ->d_name octeontx2: don't mess with ->d_parent or ->d_parent->d_name arm_scmi: don't mess with ->d_parent->d_name slub: don't mess with ->d_name sof-client-ipc-flood-test: don't mess with ->d_name qat: don't mess with ->d_name xhci: don't mess with ->d_iname mtu3: don't mess wiht ->d_iname greybus/camera - stop messing with ->d_iname mediatek: stop messing with ->d_iname netdevsim: don't embed file_operations into your structs b43legacy: make use of debugfs_get_aux() b43: stop embedding struct file_operations into their objects carl9170: stop embedding file_operations into their objects ...

wifi: mt76: move napi_enable() from under BH

2025-01-27T22:30:50Z

mt76 does a lot of: local_bh_disable(); napi_enable(...napi); napi_schedule(...napi); local_bh_enable(); local_bh_disable() is not a real lock, its most likely taken because napi_schedule() requires that we invoke softirqs at some point. napi_enable() needs to take a mutex, so move it from under the BH protection.

Pull pci updates from Bjorn Helgaas: "Enumeration: - Batch sizing of multiple BARs while memory decoding is disabled instead of disabling/enabling decoding for each BAR individually; this optimizes virtualized environments where toggling decoding enable is expensive (Alex Williamson) - Add host bridge .enable_device() and .disable_device() hooks for bridges that need to configure things like Requester ID to StreamID mapping when enabling devices (Frank Li) - Extend struct pci_ecam_ops with .enable_device() and .disable_device() hooks so drivers that use pci_host_common_probe() instead of their own .probe() have a way to set the .enable_device() callbacks (Marc Zyngier) - Drop 'No bus range found' message so we don't complain when DTs don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas) - Rename the drivers/pci/of_property.c struct of_pci_range to of_pci_range_entry to avoid confusion with the global of_pci_range in include/linux/of_address.h (Bjorn Helgaas) Driver binding: - Update resource request API documentation to encourage callers to supply a driver name when requesting resources (Philipp Stanner) - Export pci_intx_unmanaged() and pcim_intx() (always managed) so callers of pci_intx() (which is sometimes managed) can explicitly choose the one they need (Philipp Stanner) -

Remove pci_intx_unmanaged() since pci_intx() is now always unmanaged and pcim_intx() is always managed (Philipp Stanner) Error handling: - Unexport pcie_read_tlp_log() to encourage drivers to use PCI core logging rather than building their own (Ilpo Järvinen) -

Write BAR_MASK before iATU registers in pci_epc_set_bar() so we don't depend on the BAR_MASK reset value being larger than the requested BAR size (Niklas Cassel) - Prevent changing BAR size/flags in pci_epc_set_bar() to prevent reads from bypassing the iATU if we reduced the BAR size (Niklas Cassel) - Verify address alignment when programming iATU so we don't attempt to write bits that are read-only because of the BAR size, which could lead to directing accesses to the wrong address (Niklas Cassel) -

wifi: qtnfmac: use always-managed version of pcim_intx()

2025-01-18T20:38:49Z

pci_intx() is a hybrid function which can sometimes be managed through devres. To remove this hybrid nature from pci_intx(), it is necessary to port users to either an always-managed or a never-managed version. qtnfmac enables its PCI device with pcim_enable_device(). Thus, it needs the always-managed version. Replace pci_intx() with pcim_intx().

wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize()

2025-01-16T19:26:30Z

On removal of the device or unloading of the kernel module a potential NULL pointer dereference occurs. The following sequence deletes the interface: brcmf_detach() brcmf_remove_interface() brcmf_del_if() Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches. After brcmf_remove_interface() call the brcmf_proto_detach() function is called providing the following sequence: brcmf_detach() brcmf_proto_detach() brcmf_proto_msgbuf_detach() brcmf_flowring_detach() brcmf_msgbuf_delete_flowring() brcmf_msgbuf_remove_flowring() brcmf_flowring_delete() brcmf_get_ifp() brcmf_txfinalize() Since brcmf_get_ip() can and actually will return NULL in this case the call to brcmf_txfinalize() will result in a NULL pointer dereference inside brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors. This will only happen if a flowring still has an skb. Although the NULL pointer dereference has only been seen when trying to update the tx statistic, all other uses of the ifp pointer have been guarded as well with an early return if ifp is NULL.

wiphy_unregister()/wiphy_free() has been recently decoupled from wilc_netdev_cleanup() to fix a faulty error path in sdio/spi probe functions. However this change introduced a new failure when simply loading then unloading the driver: $ modprobe wilc1000-sdio; modprobe -r wilc1000-sdio WARNING: CPU: 0 PID: 115 at net/wireless/core.c:1145 wiphy_unregister+0x904/0xc40 [cfg80211] Modules linked in: wilc1000_sdio(-) wilc1000 cfg80211 bluetooth ecdh_generic ecc CPU: 0 UID: 0 PID: 115 Comm: modprobe Not tainted 6.13.0-rc6+ #45 Hardware name: Atmel SAMA5 Call trace: unwind_backtrace from show_stack+0x18/0x1c show_stack from dump_stack_lvl+0x44/0x70 dump_stack_lvl from __warn+0x118/0x27c __warn from warn_slowpath_fmt+0xcc/0x140 warn_slowpath_fmt from wiphy_unregister+0x904/0xc40 [cfg80211] wiphy_unregister [cfg80211] from wilc_sdio_remove+0xb0/0x15c [wilc1000_sdio] wilc_sdio_remove [wilc1000_sdio] from sdio_bus_remove+0x104/0x3f0 sdio_bus_remove from device_release_driver_internal+0x424/0x5dc device_release_driver_internal from driver_detach+0x120/0x224 driver_detach from bus_remove_driver+0x17c/0x314 bus_remove_driver from sys_delete_module+0x310/0x46c sys_delete_module from ret_fast_syscall+0x0/0x1c Exception stack(0xd0acbfa8 to 0xd0acbff0) bfa0: 0044b210 0044b210 0044b24c 00000800 00000000 00000000 bfc0: 0044b210 0044b210 00000000 00000081 00000000 0044b210 00000000 00000000 bfe0: 00448e24 b6af99c4 0043ea0d aea2e12c irq event stamp: 0 hardirqs last enabled at (0): [<00000000>] 0x0 hardirqs last disabled at (0): [] copy_process+0x1c4c/0x7bec softirqs last enabled at (0): [] copy_process+0x1ca0/0x7bec softirqs last disabled at (0): [<00000000>] 0x0 The warning is triggered by the fact that there is still a wireless_device linked to the wiphy we are unregistering, due to wiphy_unregister() now being called after net device unregister (performed in wilc_netdev_cleanup()). Fix this warning by moving wiphy_unregister() after wilc_netdev_cleanup() is nominal paths (ie: driver removal). wilc_netdev_cleanup() ordering is left untouched in error paths in probe function because net device is not registered in those paths (so the warning can not trigger), yet the wiphy can still be registered, and we still some cleanup steps from wilc_netdev_cleanup().
