However if the firmware limit isn't changed (MEGASAS_MAX_SGE = 128), the code ends doing the same check twice. Per the maintainer [*]: > The original code assumed that one could change MFI_PASS_FRAME_SIZE, > but it turned out not to be possible as it's being hardcoded in the > drivers themselves (even though the interface provides mechanisms to > query it).

2023-06-13riscv/virt: Support using pflash via -blockdev optionSunil V L
Currently, pflash devices can be configured only via -pflash or -drive options. This is the legacy way and the better way is to use -blockdev as in other architectures. libvirt also has moved to use -blockdev method. To support -blockdev option, pflash devices need to be created in instance_init itself. So, update the code to move the virt_flash_create() to instance_init. Also, use standard interfaces to detect whether pflash0 is configured or not.

2023-06-13hw/riscv: virt: Assume M-mode FW in pflash0 only when "-bios none"Sunil V L
Currently, virt machine supports two pflash instances each with 32MB size. However, the first pflash is always assumed to contain M-mode firmware and reset vector is set to this if enabled. Hence, for S-mode payloads like EDK2, only one pflash instance is available for use. This means both code and NV variables of EDK2 will need to use the same pflash. The OS distros keep the EDK2 FW code as readonly. When non-volatile variables also need to share the same pflash, it is not possible to keep it as readonly since variables need write access. To resolve this issue, the code and NV variables need to be separated. But in that case we need an extra flash. Hence, modify the convention for non-KVM guests such that, pflash0 will contain the M-mode FW only when "-bios none" option is used. Otherwise, pflash0 will contain the S-mode payload FW. This enables both pflash instances available for EDK2 use. When KVM is enabled, pflash0 is always assumed to contain the S-mode payload firmware only. Example usage: 1) pflash0 containing M-mode FW qemu-system-riscv64 -bios none -pflash <mmode_fw> -machine virt or qemu-system-riscv64 -bios none \ -drive file=<mmode_fw>,if=pflash,format=raw,unit=0 -machine virt 2) pflash0 containing S-mode payload like EDK2 qemu-system-riscv64 -pflash <smode_fw_code> -pflash <smode_vars> -machine virt or qemu-system-riscv64 -bios <opensbi_fw> \ -pflash <smode_fw_code> \ -pflash <smode_vars> \ -machine virt or qemu-system-riscv64 -bios <opensbi_fw> \ -drive file=<smode_fw_code>,if=pflash,format=raw,unit=0,readonly=on \ -drive file=<smode_fw_vars>,if=pflash,format=raw,unit=1 \ -machine virt Signed-off-by: Sunil V L <sunilvl@ventanamicro.com> Reported-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Tested-by: Andrea Bolognani <abologna@redhat.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-Id: <20230601045910.18646-2-sunilvl@ventanamicro.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>

2023-06-10target/ppc: Decrementer fix BookE semanticsNicholas Piggin
The decrementer store function has logic that short-cuts the timer if a very small value is stored (0, 1, or 2) and raises an interrupt directly. There are two problem with this on BookE. First is that BookE says a decrementer interrupt should not be raised on a store of 0, only of a decrement from 1. Second is that raising the irq directly will bypass the auto-reload logic in the booke decr timer function, breaking autoreload when 1 or 2 is stored. Fix this by removing that small-value special case. It makes this tricky logic even more difficult to reason about, and it hardly matters for performance.

2023-06-10target/ppc: Fix decrementer time underflow and infinite timer loopNicholas Piggin
It is possible to store a very large value to the decrementer that it does not raise the decrementer exception so the timer is scheduled, but the next time value wraps and is treated as in the past. This can occur if (u64)-1 is stored on a zero-triggered exception, or (u64)-1 is stored twice on an underflow-triggered exception, for example. If such a value is set in DECAR, it gets stored to the decrementer by the timer function, which then immediately causes another timer, which hangs QEMU. Clamp the decrementer to the implemented width, and use that as the value for the timer calculation, effectively preventing this overflow.

2023-06-10pnv/xive2: Quiet down some error messagesFrederic Barrat
When dumping the END and NVP tables ("info pic" from the HMP) on the P10 model, we're likely to be flooded with error messages such as: XIVE[0] - VST: invalid NVPT entry f33800 !? The error is printed when finding an empty VSD in an indirect table (thus END and NVP tables with skiboot), which is going to happen when dumping the xive state. So let's tune down those messages. They can be re-enabled easily with a macro if needed. Those errors were already hidden on xive/P9, for the same reason.

2023-06-10pnv/xive2: Handle TIMA access through all portsFrederic Barrat
The Thread Interrupt Management Area (TIMA) can be accessed through 4 ports, targeted by the address. The base address of a TIMA is using port 0 and the other ports are 0x80 apart. Using one port or another can be useful to balance the load on the snoop buses. With skiboot and linux, we currently use port 0, but as it tends to be busy, another hypervisor is using port 1 for TIMA access. The port address bits fall in between the special op indication bits (the 2 MSBs) and the register offset bits (the 6 LSBs). They are "don't care" for the hardware when processing a TIMA operation. This patch filters out those port address bits so that a TIMA operation can be triggered using any port. It is also true for indirect access (through the IC BAR) and it's actually nothing new, it was already the case on P9. Which helps here, as the TIMA handling code is common between P9 (xive) and P10 (xive2).

Fix what was probably a silly mistake and allow to write the Physical Thread enable registers 0 and 1. Skiboot prefers to use the ENx_SET variant so it went unnoticed, but there's no reason to discard a write to the full register, it is Read-Write.

2023-06-089pfs: prevent opening special files (CVE-2023-2861)Christian Schoenebeck
The 9p protocol does not specifically define how server shall behave when client tries to open a special file, however from security POV it does make sense for 9p server to prohibit opening any special file on host side in general. A sane Linux 9p client for instance would never attempt to open a special file on host side, it would always handle those exclusively on its guest side. A malicious client however could potentially escape from the exported 9p tree by creating and opening a device file on host side. With QEMU this could only be exploited in the following unsafe setups: - Running QEMU binary as root AND 9p 'local' fs driver AND 'passthrough' security model. or - Using 9p 'proxy' fs driver (which is running its helper daemon as root). These setups were already discouraged for safety reasons before, however for obvious reasons we are now tightening behaviour on this.

2023-06-07hw/xen: Simplify emulated Xen platform initDavid Woodhouse
I initially put the basic platform init (overlay pages, grant tables, event channels) into mc->kvm_type because that was the earliest place that could sensibly test for xen_mode==XEN_EMULATE. The intent was to do this early enough that we could then initialise the XenBus and other parts which would have depended on them, from a generic location for both Xen and KVM/Xen in the PC-specific code, as seen in https://lore.kernel.org/qemu-devel/20230116221919.1124201-16-dwmw2@infradead.org/ However, then the Xen on Arm patches came along, and *they* wanted to do the XenBus init from a 'generic' Xen-specific location instead: https://lore.kernel.org/qemu-devel/20230210222729.957168-4-sstabellini@kernel.org/ Since there's no generic location that covers all three, I conceded to do it for XEN_EMULATE mode in pc_basic_devices_init(). And now there's absolutely no point in having some of the platform init done from pc_machine_kvm_type(); we can move it all up to live in a single place in pc_basic_devices_init(). This has the added benefit that we can drop the separate xen_evtchn_connect_gsis() function completely, and pass just the system GSIs in directly to xen_evtchn_create(). While I'm at it, it does no harm to explicitly pass in the *number* of said GSIs, because it does make me twitch a bit to pass an array of impicit size. During the lifetime of the KVM/Xen patchset, that had already changed (albeit just cosmetically) from GSI_NUM_PINS to IOAPIC_NUM_PINS. And document a bit better that this is for the *output* GSI for raising CPU0's events when the per-CPU vector isn't available. The fact that we create a whole set of them and then only waggle the one we're told to, instead of having a single output and only *connecting* it to the GSI that it should be connected to, is still non-intuitive for me.
