vfio-pci: Fault mmaps to enable vma tracking
Rather than calling remap_pfn_range() when a region is mmap'd, setup a vm_ops handler to support dynamic faulting of the range on access. This allows us to manage a list of vmas actively mapping the area that we can later use to invalidate those mappings. The open callback invalidates the vma range so that all tracking is inserted in the fault handler and removed in the close handler.

vfio/type1: Support faulting PFNMAP vmas
With conversion to follow_pfn(), DMA mapping a PFNMAP range depends on the range being faulted into the vma. Add support to manually provide that, in the same way as done on KVM with hva_to_pfn_remapped().

Convert i2c_new_device() to i2c_new_client_device()
Wolfram Sang has asked to have this included in 5.7 so the deprecated API can be removed next release. There should be no functional difference. I think that entire this section of code can be removed; it is leftover from other things that have since changed, but this is the safer thing to do for now. The full removal can happen next release.

Some more clk driver fixes for the merge window and one core framework
fix:
- A handful of TI driver fixes for bad of_node_put() and incorrect
parent names
- Rockchip rk3228 aclk_gpu* creation was interfering with lima GPU work
so we use a composite clk now
- Resuming from suspend on Tegra Jetson TK1 was broken because an audio
PLL calculated an incorrect rate
- A fix for devicetree probing on IM-PD1 by actually specifying a clk
name which is required to pass clk registration
- Avoid list corruption if registration fails for a critical clk

exec: Move would_dump into flush_old_exec
I goofed when I added mm->user_ns support to would_dump. I missed the
fact that in the case of binfmt_loader, binfmt_em86, binfmt_misc, and
binfmt_script bprm->file is reassigned. Which made the move of
would_dump from setup_new_exec to __do_execve_file before exec_binprm
incorrect as it can result in would_dump running on the script instead
of the interpreter of the script.
The net result is that the code stopped making unreadable interpreters
undumpable. Which allows them to be ptraced and written to disk
without special permissions. Oops.
The move was necessary because the call in set_new_exec was after
bprm->mm was no longer valid.
To correct this mistake move the misplaced would_dump from
__do_execve_file into flos_old_exec, before exec_mmap is called.
I tested and confirmed that without this fix I can attach with gdb to
a script with an unreadable interpreter, and with this fix I can not.

powerpc fixes for 5.7 #4
A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the recent rewrite of interrupt exit in C. Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit. These are all fairly minor with the exception of the change to evaluate the get/put_user() arguments before we enable user access, which reduces the amount of code we run with user access enabled. A fix for our secure boot IMA rules, if enforcement of module signatures is enabled at runtime rather than build time. A fix to our 32-bit VDSO clock_getres() which wasn't falling back to the syscall for unknown clocks. A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another for 40x.

ARM: SoC/dt fixes for v5.7
This round of fixes is almost exclusively device tree changes,
with trivial defconfig fixes and one compiler warning fix
added in.
A number of patches are to fix dtc warnings, in particular on
Amlogic, i.MX and Rockchips.
Other notable changes include:
Renesas:
- Fix a wrong clock configuration on R-Mobile A1,
- Fix IOMMU support on R-Car V3H
Allwinner
- Multiple audio fixes
Qualcomm
- Use a safe CPU voltage on MSM8996
- Fixes to match a late audio driver change
Rockchip:
- Some fixes for the newly added Pinebook Pro
NXP i.MX:
- Fix I2C1 pinctrl configuration for i.MX27 phytec-phycard board.
- Fix imx6dl-yapp4-ursa board Ethernet connection.
OMAP:
- A regression fix for non-existing can device on am534x-idk
- Fix flakey wlan on droid4 where some devices would not connect
at all because of internal pull being used with an external pull
- Fix occasional missed wake-up events on droid4 modem uart

RISC-V Fixes for 5.7-rc6

None of these patches should have any functional impact on kernels that build, and they're mostly related to various features intermingling with !MMU.

dpaa2-eth: properly handle buffer size restrictions
Depending on the WRIOP version, the buffer size on the RX path must by a
multiple of 64 or 256. Handle this restriction properly by aligning down
the buffer size to the necessary value. Also, use the new buffer size
dynamically computed instead of the compile time one.

USB: gadget: fix illegal array access in binding with UDC
FuzzUSB (a variant of syzkaller) found an illegal array access using an incorrect index while binding a gadget with UDC. Reference: https://www.spinics.net/lists/linux-usb/msg194331.html This bug occurs when a size variable used for a buffer is misused to access its strcpy-ed buffer. Given a buffer along with its size variable (taken from user input), from which, a new buffer is created using kstrdup(). Due to the original buffer containing 0 value in the middle, the size of the kstrdup-ed buffer becomes smaller than that of the original. So accessing the kstrdup-ed buffer with the same size variable triggers memory access violation. The fix makes sure no zero value in the buffer, by comparing the strlen() of the orignal buffer with the size variable, so that the access to the kstrdup-ed buffer is safe.

USB: fixes for v5.7-rc6
The main part here are the important fixes for the raw-gadget before it becomes an ABI. We're adding support for stall/halt/wedge which is actually pretty important in many situations. There's also a NULL pointer deref fix. Apart from raw-gadget, I've included some recent sparse fixes to a few drivers.

x86: Fix early boot crash on gcc-10, third try
... or the odyssey of trying to disable the stack protector for the function which generates the stack canary value. The whole story started with Sergei reporting a boot crash with a kernel built with gcc-10: Kernel panic — not syncing: stack-protector: Kernel stack is corrupted in: start_secondary CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.6.0-rc5—00235—gfffb08b37df9 #139 Hardware name: Gigabyte Technology Co., Ltd. To be filled by O.E.M./H77M—D3H, BIOS F12 11/14/2013 Call Trace: dump_stack panic ? start_secondary __stack_chk_fail start_secondary secondary_startup_64 -—-[ end Kernel panic — not syncing: stack—protector: Kernel stack is corrupted in: start_secondary This happens because gcc-10 tail-call optimizes the last function call in start_secondary() - cpu_startup_entry() - and thus emits a stack canary check which fails because the canary value changes after the boot_init_stack_canary() call. To fix that, the initial attempt was to mark the one function which generates the stack canary with: __attribute__((optimize("-fno-stack-protector"))) ... start_secondary(void *unused) however, using the optimize attribute doesn't work cumulatively as the attribute does not add to but rather replaces previously supplied optimization options - roughly all -fxxx options. The key one among them being -fno-omit-frame-pointer and thus leading to not present frame pointer - frame pointer which the kernel needs. The next attempt to prevent compilers from tail-call optimizing the last function call cpu_startup_entry(), shy of carving out start_secondary() into a separate compilation unit and building it with -fno-stack-protector, was to add an empty asm(""). This current solution was short and sweet, and reportedly, is supported by both compilers but we didn't get very far this time: future (LTO?) optimization passes could potentially eliminate this, which leads us to the third attempt: having an actual memory barrier there which the compiler cannot ignore or move around etc. That should hold for a long time, but hey we said that about the other two solutions too so...

x86/unwind/orc: Fix error handling in __unwind_start()
The unwind_state 'error' field is used to inform the reliable unwinding code that the stack trace can't be trusted. Set this field for all errors in __unwind_start(). Also, move the zeroing out of the unwind_state struct to before the ORC table initialization check, to prevent the caller from reading uninitialized data if the ORC table is corrupted. Fixes: |
