2024-03-10PCI: hv: Fix ring buffer size calculationMichael Kelley1-1/+2
For a physical PCI device that is passed through to a Hyper-V guest VM, current code specifies the VMBus ring buffer size as 4 pages. But this is an inappropriate dependency, since the amount of ring buffer space needed is unrelated to PAGE_SIZE. For example, on x86 the ring buffer size ends up as 16 Kbytes, while on ARM64 with 64 Kbyte pages, the ring size bloats to 256 Kbytes. The ring buffer for PCI pass-thru devices is used for only a few messages during device setup and removal, so any space above a few Kbytes is wasted. Fix this by declaring the ring buffer size to be a fixed 16 Kbytes. Furthermore, use the VMBUS_RING_SIZE() macro so that the ring buffer header is properly accounted for, and so the size is rounded up to a page boundary, using the page size for which the kernel is built. While w/64 Kbyte pages this results in a 64 Kbyte ring buffer header plus a 64 Kbyte ring buffer, that's the smallest possible with that page size. It's still 128 Kbytes better than the current code.

The commit message in commit fc9a77040b04 ("PCI: designware-ep: Configure Resizable BAR cap to advertise the smallest size") claims that it modifies the Resizable BAR capability to only advertise support for 1 MB size BARs. However, the commit writes all zeroes to PCI_REBAR_CAP (the register which contains the possible BAR sizes that a BAR be resized to). According to the spec, it is illegal to not have a bit set in PCI_REBAR_CAP, and 1 MB is the smallest size allowed. Set bit 4 in PCI_REBAR_CAP, so that we actually advertise support for a 1 MB BAR size.

2024-03-10PCI: qcom: Enable BDF to SID translation properlyManivannan Sadhasivam1-0/+10
Qcom SoCs making use of ARM SMMU require BDF to SID translation table in the driver to properly map the SID for the PCIe devices based on their BDF identifier. This is currently achieved with the help of qcom_pcie_config_sid_1_9_0() function for SoCs supporting the 1_9_0 config. But With newer Qcom SoCs starting from SM8450, BDF to SID translation is set to bypass mode by default in hardware. Due to this, the translation table that is set in the qcom_pcie_config_sid_1_9_0() is essentially unused and the default SID is used for all endpoints in SoCs starting from SM8450. This is a security concern and also warrants swapping the DeviceID in DT while using the GIC ITS to handle MSIs from endpoints. The swapping is currently done like below in DT when using GIC ITS: /* * MSIs for BDF (1:0.0) only works with Device ID 0x5980. * Hence, the IDs are swapped. */ msi-map = <0x0 &gic_its 0x5981 0x1>, <0x100 &gic_its 0x5980 0x1>; Here, swapping of the DeviceIDs ensure that the endpoint with BDF (1:0.0) gets the DeviceID 0x5980 which is associated with the default SID as per the iommu mapping in DT. So MSIs were delivered with IDs swapped so far. But this also means the Root Port (0:0.0) won't receive any MSIs (for PME, AER etc...) So let's fix these issues by clearing the BDF to SID bypass mode for all SoCs making use of the 1_9_0 config. This allows the PCIe devices to use the correct SID, thus avoiding the DeviceID swapping hack in DT and also achieving the isolation between devices.

2024-03-09virt: efi_secret: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-03-09x86/efistub: Remap kernel text read-only before dropping NX attributeArd Biesheuvel1-1/+10
Currently, the EFI stub invokes the EFI memory attributes protocol to strip any NX restrictions from the entire loaded kernel, resulting in all code and data being mapped read-write-execute. The point of the EFI memory attributes protocol is to remove the need for all memory allocations to be mapped with both write and execute permissions by default, and make it the OS loader's responsibility to transition data mappings to code mappings where appropriate. Even though the UEFI specification does not appear to leave room for denying memory attribute changes based on security policy, let's be cautious and avoid relying on the ability to create read-write-execute mappings. This is trivially achievable, given that the amount of kernel code executing via the firmware's 1:1 mapping is rather small and limited to the .head.text region. So let's drop the NX restrictions only on that subregion, but not before remapping it as read-only first. Signed-off-by: Ard Biesheuvel <[email protected]>

Our efi_tcg2_tagged_event is not defined in the EFI spec, but it is not a local invention either: it was taken from the TCG PC Client spec, where it is called TCG_PCClientTaggedEvent. Note that this spec also contains some guidance on how to populate it, which is not being followed closely at the moment; it claims that the event size should cover the TCG_PCClientTaggedEvent and its payload only, but it currently covers the preceding efi_tcg2_event too. However, this directly contradicts the TCG EFI protocol specification, which states very clearly that the event size should cover the entire data structure, including the leading efi_tcg2_event_t struct. So rename the struct and document its provenance, but retain the existing logic to populate the size field.

The kmalloc() in zynq_clk_setup() will return null if the physical memory has run out. As a result, if we use snprintf() to write data to the null address, the null pointer dereference bug will happen. This patch uses a stack variable to replace the kmalloc().

2024-03-08clk: Fix clk_core_get NULL dereferenceBryan O'Donoghue1-0/+3
It is possible for clk_core_get to dereference a NULL in the following sequence: clk_core_get() of_clk_get_hw_from_clkspec() __of_clk_get_hw_from_provider() __clk_get_hw() __clk_get_hw() can return NULL which is dereferenced by clk_core_get() at hw->core. Prior to commit dde4eff47c82 ("clk: Look for parents with clkdev based clk_lookups") the check IS_ERR_OR_NULL() was performed which would have caught the NULL. Reading the description of this function it talks about returning NULL but that cannot be so at the moment. Update the function to check for hw before dereferencing it and return NULL if hw is NULL.

2024-03-08x86/hyperv: Use per cpu initial stack for vtl contextSaurabh Sengar1-0/+1
Currently, the secondary CPUs in Hyper-V VTL context lack support for parallel startup. Therefore, relying on the single initial_stack fetched from the current task structure suffices for all vCPUs. However, common initial_stack risks stack corruption when parallel startup is enabled. In order to facilitate parallel startup, use the initial_stack from the per CPU idle thread instead of the current task.

2024-03-08clk: starfive: jh7110-vout: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Both AER and DPC RP PIO provide TLP Header Log registers (PCIe r6.1 secs 7.8.4 & 7.9.14) to convey error diagnostics but the struct is named after AER as the struct aer_header_log_regs. Also, not all places that handle TLP Header Log use the struct and the struct members are named individually. Generalize the struct name and members, and use it consistently where TLP Header Log is being handled so that a pcie_read_tlp_log() helper can be easily added.
