of/fdt: Don't calculate initrd size from DT if start > end
If the properties 'linux,initrd-start' and 'linux,initrd-end' of
the chosen node populated from the bootloader, eg. U-Boot, are so that
start > end, then the phys_initrd_size calculated from end - start is
negative that subsequently gets converted to a high positive value for
being unsigned long long. Then, the memory region with the (invalid)
size is added to the bootmem and attempted being paged in paging_init()
that results in the kernel fault.
For example, on the FVP ARM64 system I'm running, the U-Boot populates
the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0.
The phys_initrd_size calculated is then ffff_ffff_7800_0000
(= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then
attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es
as below.
It should be stressed, it is generally a fault of the bootloader's with
the kernel relying on it, however we should not allow the bootloader's
misconfiguration to lead to the kernel oops. Not only the kernel should be
bullet proof against it but also finding the root cause of the paging
fault spanning over the bootloader, DT, and kernel may happen is not so
easy.

of: irq: Report individual failures in of_irq_init()
New pr_err(), a copy of preceeding pr_debug(), faciliates debugging. This change was inspired by a long lasting debugging of the octeon_irq_init_ciu() which fails completely silently and leaves the interrupt controller half-way configured which in turn had very non-obvious effects.

of: unittest: taint the kernel when of unittest runs
Make OF unittest trigger the new TAINT_TEST taint when OF unittest runs. Due to OF unittest not being intended to run on production systems, and potentially causing problems (or security issues like leaking kernel addresses), the kernel's state should not be considered safe for production use after OF unittest runs.

RISC-V Patches for the 5.20 Merge Window, Part 2
There's still a handful of new features in here, but there are a lot of
fixes/cleanups as well:
* Support for the Zicbom for explicit cache-block management, along with
the necessary bits to make the non-standard cache management ops on
the Allwinner D1 function.
* Support for the Zihintpause extension, which codifies a go-slow
instruction used for cpu_relax().
* Support for the Sstc extension for supervisor-mode timer/counter
management.
* Many device tree fixes and cleanups, including a large set for the
Canaan device trees.
* A handful of fixes and cleanups for the PMU driver.

riscv: implement Zicbom-based CMO instructions + the t-head variant
This series is based on the alternatives changes done in my svpbmt series and thus also depends on Atish's isa-extension parsing series. It implements using the cache-management instructions from the Zicbom- extension to handle cache flush, etc actions on platforms needing them. SoCs using cpu cores from T-Head like the Allwinne D1 implement a different set of cache instructions. But while they are different, instructions they provide the same functionality, so a variant can easly hook into the existing alternatives mechanism on those. [Palmer: Some minor fixups, including a RISCV_ISA_ZICBOM dependency on MMU that's probably not strictly necessary. The Zicbom support will trip up sparse for users that have new toolchains, I just sent a patch.] Link: https://lore.kernel.org/all/20220706231536.2041855-1-heiko@sntech.de/ Link: https://lore.kernel.org/linux-sparse/20220811033138.20676-1-palmer@rivosinc.com/T/#u * palmer/riscv-zicbom: riscv: implement cache-management errata for T-Head SoCs riscv: Add support for non-coherent devices using zicbom extension dt-bindings: riscv: document cbom-block-size of: also handle dma-noncoherent in of_dma_is_coherent() |

TTY / Serial driver changes for 6.0-rc1
Here is the big set of tty and serial driver changes for 6.0-rc1. It was delayed from last week as I wanted to make sure the last commit here got some good testing in linux-next and elsewhere as it seemed to show up only late in testing for some reason. Nothing major here, just lots of cleanups from Jiri and Ilpo to make the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo). Also included in here is the obligatory n_gsm updates from Daniel Starke and lots of tiny driver updates and minor fixes and tweaks for other smaller serial drivers. Full details are in the shortlog.

Driver core / kernfs changes for 6.0-rc1
Here is the set of driver core and kernfs changes for 6.0-rc1.
"biggest" thing in here is some scalability improvements for kernfs for
large systems. Other than that, included in here are:
- arch topology and cache info changes that have been reviewed
and discussed a lot.
- potential error path cleanup fixes
- deferred driver probe cleanups
- firmware loader cleanups and tweaks
- documentation updates
- other small things
All of these have been in the linux-next tree for a while with no
reported problems.

of: also handle dma-noncoherent in of_dma_is_coherent()
of_dma_is_coherent() currently expects the architecture to be non-coherent and some devices being coherent getting marked as such with the dma-coherent devicetree property. For PowerPC CONFIG_OF_DMA_DEFAULT_COHERENT was added which currently makes of_dma_is_coherent() always return true but doesn't handle the case of the architecture being coherent but some devices not. So modify the function to also check for dma-noncoherent and set a suitable default return value. If CONFIG_OF_DMA_DEFAULT_COHERENT is set the value starts with true and finding dma-noncoherent will set it to false and without CONFIG_OF_DMA_DEFAULT_COHERENT, the behaviour is reversed.

x86/kexec: Carry forward IMA measurement log on kexec
On kexec file load, the Integrity Measurement Architecture (IMA) subsystem may verify the IMA signature of the kernel and initramfs, and measure it. The command line parameters passed to the kernel in the kexec call may also be measured by IMA. A remote attestation service can verify a TPM quote based on the TPM event log, the IMA measurement list and the TPM PCR data. This can be achieved only if the IMA measurement log is carried over from the current kernel to the next kernel across the kexec call. PowerPC and ARM64 both achieve this using device tree with a "linux,ima-kexec-buffer" node. x86 platforms generally don't make use of device tree, so use the setup_data mechanism to pass the IMA buffer to the new kernel.

earlycon: prevent multiple register_console()
If the earlycon parameter is given twice, the kernel will spit out a WARN() in register_console() because it was already registered. The non-dt variant setup_earlycon() already handles that gracefully. The dt variant of_setup_earlycon() doesn't. Add the check there and add the -EALREADY handling in early_init_dt_scan_chosen_stdout(). FWIW, this doesn't happen if CONFIG_ACPI_SPCR_TABLE is set. In that case the registration is delayed until after earlycon parameter(s) are parsed.

mm: kmemleak: remove kmemleak_not_leak_phys() and the min_count argument to kmemleak_alloc_phys()
Patch series "mm: kmemleak: store objects allocated with physical address separately and check when scan", v4. The kmemleak_*_phys() interface uses "min_low_pfn" and "max_low_pfn" to check address. But on some architectures, kmemleak_*_phys() is called before those two variables initialized. The following steps will be taken: 1) Add OBJECT_PHYS flag and rbtree for the objects allocated with physical address 2) Store physical address in objects if allocated with OBJECT_PHYS 3) Check the boundary when scan instead of in kmemleak_*_phys() This patch set will solve: https://lore.kernel.org/r/20220527032504.30341-1-yee.lee@mediatek.com https://lore.kernel.org/r/9dd08bb5-f39e-53d8-f88d-bec598a08c93@gmail.com v3: https://lore.kernel.org/r/20220609124950.1694394-1-patrick.wang.shcn@gmail.com v2: https://lore.kernel.org/r/20220603035415.1243913-1-patrick.wang.shcn@gmail.com v1: https://lore.kernel.org/r/20220531150823.1004101-1-patrick.wang.shcn@gmail.com This patch (of 4): Remove the unused kmemleak_not_leak_phys() function.

of: check previous kernel's ima-kexec-buffer against memory bounds
Presently ima_get_kexec_buffer() doesn't check if the previous kernel's
ima-kexec-buffer lies outside the addressable memory range. This can result
in a kernel panic if the new kernel is booted with 'mem=X' arg and the
ima-kexec-buffer was allocated beyond that range by the previous kernel.
The panic is usually of the form below:
$ sudo kexec --initrd initrd vmlinux --append='mem=16G'

of/fdt: Ignore disabled memory nodes
When we boot a machine using a devicetree, the generic DT code goes
through all nodes with a 'device_type = "memory"' property, and collects
all memory banks mentioned there. However it does not check for the
status property, so any nodes which are explicitly "disabled" will still
be added as a memblock.
This ends up badly for QEMU, when booting with secure firmware on
arm/arm64 machines, because QEMU adds a node describing secure-only
memory:
===================
secram@e000000 {
secure-status = "okay";
status = "disabled";
reg = <0x00 0xe000000 0x00 0x1000000>;
device_type = "memory";
};
===================
The kernel will eventually use that memory block (which is located below
the main DRAM bank), but accesses to that will be answered with an
SError:
===================
[ 0.000000] Internal error: synchronous external abort: 96000050 [#1] PREEMPT SMP
[ 0.000000] Modules linked in:
[ 0.000000] CPU: 0 PID: 0 Comm: swapper Not tainted 5.18.0-rc6-00014-g10c8acb8b679 #524
[ 0.000000] Hardware name: linux,dummy-virt (DT)
[ 0.000000] pstate: 200000c5 (nzCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--)
[ 0.000000] pc : new_slab+0x190/0x340
[ 0.000000] lr : new_slab+0x184/0x340
[ 0.000000] sp : ffff80000a4b3d10
....
==================
The actual crash location and call stack will be somewhat random, and
depend on the specific allocation of that physical memory range.
As the DT spec[1] explicitly mentions standard properties, add a simple
check to skip over disabled memory nodes, so that we only use memory
that is meant for non-secure code to use.
That fixes booting a QEMU arm64 VM with EL3 enabled ("secure=on"), when
not using UEFI. In this case the QEMU generated DT will be handed on
to the kernel, which will see the secram node.
This issue is reproducible when using TF-A together with U-Boot as
firmware, then booting with the "booti" command.
When using U-Boot as an UEFI provider, the code there [2] explicitly
filters for disabled nodes when generating the UEFI memory map, so we
are safe.
EDK/2 only reads the first bank of the first DT memory node [3] to learn
about memory, so we got lucky there.

When "crashkernel=X,high" is used, there may be two crash regions: high=crashk_res and low=crashk_low_res. But now the syscall kexec_file_load() only add crashk_res into "linux,usable-memory-range", this may cause the second kernel to have no available dma memory. Fix it like kexec-tools does for option -c, add both 'high' and 'low' regions into the dtb.

of: fdt: Add memory for devices by DT property "linux,usable-memory-range"
When reserving crashkernel in high memory, some low memory is reserved
for crash dump kernel devices and never mapped by the first kernel.
This memory range is advertised to crash dump kernel via DT property
under /chosen,
linux,usable-memory-range = <BASE1 SIZE1 [BASE2 SIZE2]>
We reused the DT property linux,usable-memory-range and made the low
memory region as the second range "BASE2 SIZE2", which keeps compatibility
with existing user-space and older kdump kernels.
Crash dump kernel reads this property at boot time and call memblock_add()
to add the low memory region after memblock_cap_memory_range() has been
called.

of: overlay: add entry to of_overlay_action_name[]
The values of enum of_overlay_notify_action are used to index into
array of_overlay_action_name. Add an entry to of_overlay_action_name
for the value recently added to of_overlay_notify_action.
Array of_overlay_action_name[] is moved into include/linux/of.h
adjacent to enum of_overlay_notify_action to make the connection
between the two more obvious if either is modified in the future.
The only use of of_overlay_action_name is for error reporting in
overlay_notify(). All callers of overlay_notify() report the same
error, but with fewer details. Remove the redundant error reports
in the callers.

of: overlay: rework overlay apply and remove kfree()s
Fix various kfree() issues related to of_overlay_apply().
- Double kfree() of fdt and tree when init_overlay_changeset()
returns an error.
- free_overlay_changeset() free the root of the unflattened
overlay (variable tree) instead of the memory that contains
the unflattened overlay.
- For the case of a failure during applying an overlay, move kfree()
of new_fdt and overlay_mem into free_overlay_changeset(), which
is called by the function that allocated them.
- For the case of removing an overlay, the kfree() of new_fdt and
overlay_mem remains in free_overlay_changeset().
- Check return value of of_fdt_unflatten_tree() for error instead
of checking the returned value of overlay_root.
- When storing pointers to allocated objects in ovcs, do so as
near to the allocation as possible instead of in deeply layered
function.
More clearly document policy related to lifetime of pointers into
overlay memory.

of: Create platform devices for OF framebuffers
Create a platform device for each OF-declared framebuffer and have offb bind to these devices. Allows for real hot-unplugging and other drivers besides offb. Originally, offb created framebuffer devices while initializing its module by parsing the OF device tree. No actual Linux device was set up. This tied OF framebuffers to offb and makes writing other drivers for the OF framebuffers complicated. The absence of a Linux device further prevented real hot-unplugging. Adding a distinct platform device for each OF framebuffer solves both problems. Specifically, a DRM driver can now provide graphics output for modern userspace. Some of the offb init code is now located in the OF initialization. There's now also an implementation of of_platform_default_populate_init(), which was missing before. The OF side creates different devices for either OF display nodes or BootX displays as they require different handling by the driver. The offb drivers picks up each type of device and runs the appropriate fbdev initialization. Tested with OF display nodes on qemu's ppc64le target. v3: * declare variable 'node' with function scope (Rob) v2: * run PPC code as part of existing initialization (Rob) * add a few more error warnings (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220419100405.12600-2-tzimmermann@suse.de |

If prop->length is zero, return -ENODATA.

of/irq: Use interrupts-extended to find parent
The RISC-V PLIC binding uses interrupts-extended to specify its parent
domain(s). That binding does not allow the interrupt-parent property to
appear in the irqchip node. This prevents of_irq_init from properly
detecting the irqchip hierarchy.
If no interrupt-parent property is present in the enclosing bus or root
node, then desc->interrupt_parent will be NULL for both the per-CPU
RISC-V INTC (the actual root domain) and the RISC-V PLIC. Similarly, if
the bus or root node specifies `interrupt-parent = <&plic>`, then
of_irq_init will hit the `desc->interrupt_parent == np` check, and again
all parents will be NULL. So things happen to work today for some boards
due to Makefile ordering.
However, things break when another irqchip ("foo") is stacked on top of
the PLIC. The bus or root node will have `interrupt-parent = <&foo>`,
since that is what all of the other peripherals need. When of_irq_init
runs, it will try to find the PLIC's parent domain. of_irq_find_parent
will fall back to using the interrupt-parent property of the PLIC's
parent node (i.e. the bus or root node), and of_irq_init will see "foo"
as the PLIC's parent domain. But this is wrong, because "foo" is
actually the PLIC's child domain!
So of_irq_init wrongly attempts to init the stacked irqchip before the
PLIC. This fails and breaks booting.
Fix this by using the first node referenced by interrupts-extended as
the parent when that property is present. This allows of_irq_init to see
the relationship between the PLIC and the per-CPU RISC-V INTC, and thus
only the RISC-V INTC is (correctly) considered a root domain.
