of: address: Report error on resource bounds overflow
The members "start" and "end" of struct resource are of type "resource_size_t" which can be 32bit wide. Values read from OF however are always 64bit wide. Avoid silently truncating the value and instead return an error value. This can happen on real systems when the DT was created for a PAE-enabled kernel and a non-PAE kernel is actually running. For example with an arm defconfig and "qemu-system-arm -M virt".

video/aperture: optionally match the device in sysfb_disable()
In aperture_remove_conflicting_pci_devices(), we currently only
call sysfb_disable() on vga class devices. This leads to the
following problem when the pimary device is not VGA compatible:
1. A PCI device with a non-VGA class is the boot display
2. That device is probed first and it is not a VGA device so
sysfb_disable() is not called, but the device resources
are freed by aperture_detach_platform_device()
3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()
4. NULL pointer dereference via sysfb_disable() since the resources
have already been freed by aperture_detach_platform_device() when
it was called by the other device.
Fix this by passing a device pointer to sysfb_disable() and checking
the device to determine if we should execute it or not.
v2: Fix build when CONFIG_SCREEN_INFO is not set
v3: Move device check into the mutex
Drop primary variable in aperture_remove_conflicting_pci_devices()
Drop __init on pci sysfb_pci_dev_is_enabled()
Fixes:

OF: Simplify of_iommu_configure()
We no longer have a notion of partially-initialised fwspecs existing, and we also no longer need to use an iommu_ops pointer to return status to of_dma_configure(). Clean up the remains of those, which lends itself to clarifying the logic around the dma_range_map allocation as well.

of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()
Factor out the parsing of interrupt-map interrupt parent phandle and its arg cells to a separate function, of_irq_parse_imap_parent(), so that it can be used in other parsing scenarios (e.g. fw_devlink). There was a refcount leak on non-matching entries when iterating thru "interrupt-map" which is fixed.

Networking changes for 6.10.
Core & protocols ---------------- - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked, and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code -------------------------------------------- - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter --------- - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step.

AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().

of: property: Add fw_devlink support for interrupt-map property
Some of the PCI host controllers (such as generic PCI host controller) use "interrupt-map" DT property to describe the mapping between PCI endpoints and PCI interrupt pins. This is the only case where the interrupts are not described in DT. Currently, there is no fw_devlink created based on "interrupt-map" DT property so interrupt controller is not guaranteed to be probed before the PCI host controller. This affects every platform where both PCI host controller and interrupt controllers are probed as regular platform devices. This creates fw_devlink between consumers (PCI host controller) and supplier (interrupt controller) based on "interrupt-map" DT property.

of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).
Fixes:

of: reserved_mem: Remove the use of phandle from the reserved_mem APIs
The __find_rmem() function is the only place that references the phandle field of the reserved_mem struct. __find_rmem() is used to match a device_node object to its corresponding entry in the reserved_mem array using its phandle value. But, there is already a function called of_reserved_mem_lookup() which carries out the same action using the name of the node. Using the of_reserved_mem_lookup() function is more reliable because every node is guaranteed to have a name, but not all nodes will have a phandle. Nodes are only assigned a phandle if they are explicitly defined in the DT using "phandle = <phandle_number>", or if they are referenced by another node in the DT. Hence, If the phandle field is empty, then __find_rmem() will return a false negative. Hence, delete the __find_rmem() function and switch to using the of_reserved_mem_lookup() function to find the corresponding entry of a device_node in the reserved_mem array. Since the phandle field of the reserved_mem struct is now unused, delete that as well.

STM32 Firewall bus for v6.10, round 1
Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. -----BEGIN PGP SIGNATURE----- iQJRBAABCgA7FiEEctl9+nxzUSUqdELdf5rJavIecIUFAmYqUUkdHGFsZXhhbmRy ZS50b3JndWVAZm9zcy5zdC5jb20ACgkQf5rJavIecIWolxAAqUHuLzXyrsCGfPG9 L5J8dUIeRk6lsQgO62EtS/hsUL5NhlwSiShtNilGw0t2TDCj0LpSMccwDjHoC1DE 9ks6aj0lO4dBl/d6fQm+4Vn85KiKfKYXW3J9w+6ZtG7pRly9jbmlrELqBIbL+MjU /mmPdKM5y/l9KO6vxiua+EtDdd0pZksZLFtms23VoiFgkQ+2heoJ297QGfrWwxzv UZg/UnWpQYB10dp93WL97vTdBZR4iUwEJNcip7xM65iBwSkuc9Y3gz0TZTO0ivZJ BRsNc/9BJYEV3kNxRJGyf7JeufsaG3meHVxw9sOYi2hMe75pDAANYxvsCYt6NHjL i+zugtcM5v//Ksw+HbD1rvRuhEWjFUotCeXJb+RaiY0Sy3HVlKG0WJm2Ybgzlbf+ vahskAHJxG0NFhPVpktQ/+gh8IU8Gy0PwyErdihhWKCiYBp8xHxW7IF7JtqlXQQS KQ4r0Ez/fgGmLQqDobskE+OgaFIuI5QrjH7S/VvxYh0xxZOBK89EmxK7pO3fki0v EFcTE/82HWfJo/bRCoq2Yzrh2omjR9ICsxDtVe4nILzjhaLChBz5lITyRO+/+Lr3 6u/oO09tlQYEK4YzH2Kw0xGtpY7Xfmm4wC+zDTRXKBM3Vp1IoTchHssLS4nZbScq ZHJHRPMCX98FdVH3BLX7OSexJys= =/Cu0 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmYwAI4ACgkQYKtH/8kJ UicByw//VzXycIdrOzZeInbrhs0D/7pmb31U1NaAwtK3Y90lxBi5AlB4MKUrM+oq x/cxqmmW1RsBc2m1iEuJWkqXS+XJHGptHKAHUqVhI9bIuBZqmGddvcP93Ml9egcN OL/Kd/OS4Q07EYc/Md6XrRBo2zJcHT57jGH8fKBmX4eAKfPYo7xgbq5k/0LoCq/i cgfQdKeDsR6tTrHyJI0p/+EgS5uglUnIJBm1aLDk883UKH4/EQSR+dpvYsogBcbd UnH78QeUymCOYzWylHJHeWFgDnn9NiJy/oCQx7wMc6PVUhcd0l1FXvM7XUeDy7iW aNJpgYU8cTx9IYPGBbZJ13NX0+X4QACKpDjJZG90/y4Q4YEn5l/Di9rmv4HYhZgr gwYD4EHewKB3PVtmCCUQpurSblshoo9bPWEaR3NFD1mSu46Jb11/zgIQ4oBagixV MjiaaP3+Rpz1X0Zo5HSq9F0k4A/SddOo2zjMn3af/77nENsR3yEmPWgL20T+nv9P deJ/LqE6mGVFI0c4E2K03Y85wldN6xXyhvCEqlHtK2X4l5JMe+0Vnak+VICZ0jQw K/ihBRbifMH7g4GQUjpJUoUAvoyeSJ2jhMF8QV7bk76b6HeRFRYKOpQLnj29v/nd MF2rKJwFYqJDF3d2a90I3E8c7huKnqWHQWinKu2Y2NkmH/tqtcI= =mgY+ -----END PGP SIGNATURE----- Merge tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/drivers STM32 Firewall bus for v6.10, round 1 Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms.

The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. * tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32: bus: stm32_firewall: fix off by one in stm32_firewall_get_firewall() bus: etzpc: introduce ETZPC firewall controller driver bus: rifsc: introduce RIFSC firewall controller driver of: property: fw_devlink: Add support for "access-controller" firewall: introduce stm32_firewall framework dt-bindings: bus: document ETZPC dt-bindings: bus: document RIFSC dt-bindings: treewide: add access-controllers description dt-bindings: document generic access controllers Link: https://lore.kernel.org/r/7dc64226-5429-4ab7-a8c8-6053b12e3cf5@foss.st.com Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

dma-mapping: Simplify arch_setup_dma_ops()
The dma_base, size and iommu arguments are only used by ARM, and can now easily be deduced from the device itself, so there's no need to pass them through the callchain as well.

dma-mapping: Add helpers for dma_range_map bounds
Several places want to compute the lower and/or upper bounds of a dma_range_map, so let's factor that out into reusable helpers.

OF: Simplify DMA range calculations
Juggling start, end, and size values for a range is somewhat redundant and a little hard to follow. Consolidate down to just using inclusive start and end, which saves us worrying about size overflows for full 64-bit ranges (note that passing a potentially-overflowed value through to arch_setup_dma_ops() is benign for all current implementations, and this is working towards removing that anyway).

OF: Retire dma-ranges mask workaround
The fixup adding 1 to the dma-ranges size may have been for the benefit of some early AMD Seattle DTs, or may have merely been a just-in-case, but either way anyone who might have deserved to get the message has hopefully seen the warning in the 9 years we've had it there. The modern dma_range_map mechanism should happily handle odd-sized ranges with no ill effect, so there's little need to care anyway now. Clean it up.
