We provide to sdbus_do_command() a pointer to a buffer to be filled with a varying number of bytes. By not providing the buffer size, the callee can not check the buffer is big enough. Pass the buffer size as argument to follow good practices. sdbus_do_command() doesn't return any error, only the size filled in the buffer. Convert the returned type to unsigned and remove the few unreachable lines in callers. This allow to check for possible overflow in sd_do_command().

2025-08-04scripts/make-release: Go back to cloning all the EDK2 submodulesPeter Maydell1-11/+9
In commit bd0da3a3d4f we changed make-release so that instead of cloning every git submodule of EDK2 we only cloned a fixed list. The original motivation for this was that one of the submodules: * was from a non-github repo * that repo had a "SSL certificate expired" failure * wasn't actually needed for the set of EDK2 binaries we build and at the time we were trying to build the EDK2 binaries in one of our CI jobs. Unfortunately this change meant that we were exposed to bugs where EDK2 adds a new submodule and the sources we ship in the release tarball won't build any more. In particular, in EDK2 commit c6bb7d54beb05 the MipiSysTLib submodule was added, causing failure of the ROM build in our tarball starting from QEMU release 8.2.0: /tmp/qemu-10.0.0/roms/edk2/MdePkg/MdePkg.dec(32): error 000E: File/directory not found in workspace Library/MipiSysTLib/mipisyst/library/include is not found in packages path: /tmp/qemu-10.0.0/roms/. /tmp/qemu-10.0.0/roms/edk2 (Building from a QEMU git checkout works fine.) In the intervening time EDK2 moved the submodule that had a problem to be one they mirrored themselves (and at time of writing all their submodules are hosted on github), and we stopped trying to build EDK2 binaries in our own CI jobs with commit 690ceb71936f9037f6. Go back to cloning every EDK2 submodule, so we don't have an untested explicit list of submodules which will break without our noticing it. This increases the size of the QEMU tarball .tar.xz file from 133M to 139M in my testing.

2025-08-04hw/ssi/aspeed_smc: Fix incorrect FMC_WDT2 register read on AST1030Jamin Lin1-1/+2
On AST1030, reading the FMC_WDT2 register always returns 0xFFFFFFFF. This issue is due to the aspeed_smc_read function, which checks for the ASPEED_SMC_FEATURE_WDT_CONTROL feature. Since AST1030 was missing this feature flag, the read operation fails and returns -1. To resolve this, add the WDT_CONTROL feature to AST1030's feature set so that FMC_WDT2 can be correctly accessed by firmware.

2025-08-01tests/tcg: Fix run for tests with specific pluginGustavo Romero4-6/+20
Commit 25aaf0cb7f (“tests/tcg: reduce the number of plugin test combinations”) added support for running tests with specific plugins passed via the EXTRA_RUNS variable. However, due to the optimization, the rules generated as a shuffled combination of tests and plugins might not cover the rules required to run the tests with a specific plugin passed via EXTRA_RUNS. This commit fixes it by correctly generating the rules for the tests that require a specific plugin to run, which are now passed via the EXTRA_RUNS_WITH_PLUGIN instead of via the EXTRA_RUNS variable. The fix essentially excludes the tests passed via EXTRA_RUNS_WITH_PLUGIN from the rules created by the shuffled combination of tests and plugins, to avoid running the tests twice, and generates the rules for the test/plugin combinations listed in the EXTRA_RUNS_WITH_PLUGIN variable.

2025-08-01target/arm: Fix handling of setting SVE registers from gdbVacha Bhavsar1-5/+12
The code to handle setting SVE registers via the gdbstub is broken: * it sets each pair of elements in the zregs[].d[] array in the wrong order for the most common (little endian) case: the least significant 64-bit value comes first * it makes no attempt to handle target_endian() * it does a simple copy out of the (target endian) gdbstub buffer into the (host endan) zregs data structure, which is wrong on big endian hosts Fix all these problems: * use ldq_p() to read from the gdbstub buffer * check target_big_endian() to see if we need to handle the 128-bit values the opposite way around Cc: qemu-stable@nongnu.org Signed-off-by: Vacha Bhavsar <vacha.bhavsar@oss.qualcomm.com> Message-id: 20250722173736.2332529-3-vacha.bhavsar@oss.qualcomm.com [PMM: adjusted commit message, fixed spacing] Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

In the code for allowing the gdbstub to set the value of an AArch64 FP/SIMD register, we weren't accounting for target_big_endian() being true.

In commit 655659a74a we fixed some bugs in the encoding of the Debug Communications Channel registers, including that we were incorrectly exposing an AArch32 register at p14, 3, c0, c5, 0. Unfortunately removing a register is a break of forwards migration compatibility for TCG, because we will fail the migration if the source QEMU passes us a cpreg which the destination QEMU does not have. We don't have a mechanism for saying "it's OK to ignore this sysreg in the inbound data", so for the 10.1 release reinstate the incorrect AArch32 register. (We probably have had other cases in the past of breaking migration compatibility like this, but we didn't notice because we didn't test and in any case not that many people care about TCG migration compatibility. KVM migration compat is not affected because for KVM we treat the kernel as the source of truth for what system registers are present.)

In framebuffer_update_display(), Coverity complains because we multiply two values of type 'int' (which will be done as a 32x32 multiply and so in theory might overflow) and then add the result to a ram_addr_t, which can be 64 bits. 4GB framebuffers are not plausible anyway, but keep Coverity happy by adding casts which force these multiplies to be done as 64x64.

2025-08-01hw/intc/arm_gicv3_kvm: Write all 1's to clear enable/activeZenghui Yu1-1/+1
KVM's userspace access interface to the GICD enable and active bits is via set/clear register pairs which implement the hardware's "write 1s to the clear register to clear the 0 bits, and write 1s to the set register to set the 1 bits" semantics. We didn't get this right, because we were writing 0 to the clear register. Writing 0 to GICD_IC{ENABLE,ACTIVE}R architecturally has no effect on interrupt status (all writes are simply ignored by KVM) and doesn't comply with the intention of "first write to the clear-reg to clear all bits". Write all 1's to actually clear the enable/active status. This didn't have any adverse effects on migration because there we start with a clean VM state; it would be guest-visible when doing a system reset, but since Linux always cleans up the register state of the GIC during bootup before it enables it most users won't have run into a problem here.

2025-08-01net/vdpa: fix potential fd leak in net_init_vhost_vdpa()Stefano Garzarella1-3/+2
Coverity reported a file descriptor leak (CID 1490785) that happens if `vhost_vdpa_get_max_queue_pairs()` returns 0, since in that case net_host_vdpa_init(), which should take ownership of the fd, is never called. vhost_vdpa_get_max_queue_pairs() returns 1 if VIRTIO_NET_F_MQ is not negotiated, or a negative error if the ioctl() fails, or the maximum number of queue pairs exposed by the device in the config space in the `max_virtqueue_pairs` field. In the VIRTIO spec we have: The device MUST set max_virtqueue_pairs to between 1 and 0x8000 inclusive, if it offers VIRTIO_NET_F_MQ. So, if `vhost_vdpa_get_max_queue_pairs()` returns 0, it's really an error since the device is violating the VIRTIO spec. Treat also `queue_pairs == 0` as an error, and jump to the `err` label, to return a negative value to the caller in any case.

2025-08-01hw/i386/amd_iommu: Fix event log generationSairaj Kodilkar2-9/+36
Current event logging code is broken, because of following issues 1. The code uses '|' instead of '&' to test the bit field, which causes vIOMMU to generate overflow interrupt for every log entry. 2. Code does not update the eventlog tail MMIO register after adding an entry to the buffer, because of which guest cannot process new entries (as head == tail means buffer is empty). 3. Compares eventlog tail (which is byte offset in the buffer) to eventlog length (which is number of maximum entries in the buffer). This causes vIOMMU to generate only fix number of event logs, after which it keeps on generating overflow interrupts, without actually resetting the log buffer. 4. Updates ComWaitInt instead of EventLogInt bitfield in Status register. Guest checks this field to see if there are new event log entries in the buffer. 5. Does not reset event log head and tail pointers when guest writes to eventlog base register. Fix above issues, so that guest can process event log entries.

2025-08-01pcie_sriov: Fix configuration and state synchronizationAkihiko Odaki1-19/+23
Fix issues in PCIe SR-IOV configuration register handling that caused inconsistent internal state due to improper write mask handling and incorrect migration behavior. Two main problems were identified: 1. VF Enable bit write mask handling: pcie_sriov_config_write() incorrectly assumed that its val parameter was already masked, causing it to ignore the actual write mask. This led to the VF Enable bit being processed even when masked, resulting in incorrect VF registration/unregistration. It is identified as CVE-2025-54567. 2. Migration state inconsistency: pcie_sriov_pf_post_load() unconditionally called register_vfs() regardless of the VF Enable bit state, creating inconsistent internal state when VFs should not be enabled. Additionally, it failed to properly update the NumVFs write mask based on the current configuration. It is identified as CVE-2025-54566. Root cause analysis revealed that both functions relied on incorrect special-case assumptions instead of properly reading and consuming the actual configuration values. This change introduces a unified consume_config() function that reads actual configuration values and synchronize the internal state without special-case assumptions. The solution only adds register read overhead in non-hot-path code while ensuring correct SR-IOV state management across configuration writes and migration scenarios.

2025-08-01virtio-net: Fix VLAN filter table reset timingAkihiko Odaki1-3/+4
Problem ------- The expected initial state of the table depends on feature negotiation: With VIRTIO_NET_F_CTRL_VLAN: The table must be empty in accordance with the specification. Without VIRTIO_NET_F_CTRL_VLAN: The table must be filled to permit all VLAN traffic. Prior to commit 06b636a1e2ad ("virtio-net: do not reset vlan filtering at set_features"), virtio_net_set_features() always reset the VLAN table. That commit changed the behavior to skip table reset when VIRTIO_NET_F_CTRL_VLAN was negotiated, assuming the table would be properly cleared during device reset and remain stable. However, this assumption breaks when a driver renegotiates features: 1. Initial negotiation without VIRTIO_NET_F_CTRL_VLAN (table filled) 2. Renegotiation with VIRTIO_NET_F_CTRL_VLAN (table will not be cleared) The problem was exacerbated by commit 0caed25cd171 ("virtio: Call set_features during reset"), which triggered virtio_net_set_features() during device reset, exposing the bug whenever VIRTIO_NET_F_CTRL_VLAN was negotiated after a device reset. Solution -------- Fix the issue by initializing the table when virtio_net_set_features() is called to change the VIRTIO_NET_F_CTRL_VLAN bit of vdev->guest_features. This approach ensures the correct table state regardless of feature negotiation sequence by performing initialization in virtio_net_set_features() as QEMU did prior to commit 06b636a1e2ad ("virtio-net: do not reset vlan filtering at set_features"). This change still preserves the goal of the commit, which was to avoid resetting the table during migration, by checking whether the VIRTIO_NET_F_CTRL_VLAN bit of vdev->guest_features is being changed; vdev->guest_features is set before virtio_net_set_features() gets called during migration. It also avoids resetting the table when the driver sets a feature bitmask with no change for the VIRTIO_NET_F_CTRL_VLAN bit, which makes the operation idempotent and its semantics cleaner. Additionally, this change ensures the table is initialized after feature negotiation and before the DRIVER_OK status bit being set for compatibility with the Linux driver before commit 50c0ada627f5 ("virtio-net: fix race between ndo_open() and virtio_device_ready()"), which did not ensure to set the DRIVER_OK status bit before modifying the table.

Without this change, the code would attempt to read invalid data at an index outside of our search range. * Incremented 'steps' using the next chain's ndescs instead of the current one. This patch corrects the loop bounds and synchronizes 'steps' and index increments. We also add a defensive sanity check against malicious or invalid descriptor counts to avoid a potential infinite loop and DoS.

2025-07-31target/arm: add support for 64-bit PMCCNTR in AArch32 modeAlex Richardson1-5/+24
In the PMUv3, a new AArch32 64-bit (MCRR/MRRC) accessor for the PMCCNTR was added. In QEMU we forgot to implement this, so only provide the 32-bit accessor. Since we have a 64-bit PMCCNTR sysreg for AArch64, adding the 64-bit AArch32 version is easy. We add the PMCCNTR to the v8_cp_reginfo because PMUv3 was added in the ARMv8 architecture. This is consistent with how we handle the existing PMCCNTR support, where we always implement it for all v7 CPUs. This is arguably something we should clean up so it is gated on ARM_FEATURE_PMU and/or an ID register check for the relevant PMU version, but we should do that as its own tidyup rather than being inconsistent between this PMCCNTR accessor and the others. Since the register name is the same as the 32-bit PMCCNTR, we set ARM_CP_NO_GDB on the 32-bit one to avoid generating an invalid GDB XML.

QEMU start failed when smp cpu < smp maxcpus , because qemu send a NULL cpu to KVM, this patch adds a check for kvm_ipi_access_regs() to fix it. run with '-smp 1,maxcpus=4,sockets=4,cores=1,threads=1' we got: Unexpected error in kvm_device_access() at ../accel/kvm/kvm-all.c:3477: qemu-system-loongarch64: KVM_SET_DEVICE_ATTR failed: Group 1073741825 attr 0x0000000000010000: Invalid argument Signed-off-by: Song Gao <gaosong@loongson.cn> Reviewed-by: Bibo Mao <maobibo@loongson.cn> Message-ID: <20250725081213.3867592-1-gaosong@loongson.cn>
2025-07-31target/loongarch: Fix valid virtual address checkingBibo Mao1-2/+2
On LoongArch64 system, the high 32 bit of 64 bit virtual address should be 0x00000[0-7]yyy or 0xffff8yyy. The bit from 47 to 63 should be all 0 or all 1. Function get_physical_address() only checks bit 48 to 63, there will be problem with the following test case. On physical machine, there is bus error report and program exits abnormally. However on qemu TCG system emulation mode, the program runs normally. The virtual address 0xffff000000000000ULL + addr and addr are treated the same on TLB entry checking. This patch fixes this issue. void main() { void *addr, *addr1; int val; addr = malloc(100); *(int *)addr = 1; addr1 = 0xffff000000000000ULL + addr; val = *(int *)addr1; printf("val %d \n", val); } Cc: qemu-stable@nongnu.org Signed-off-by: Bibo Mao <maobibo@loongson.cn> Acked-by: Song Gao <gaosong@loongson.cn> Reviewed-by: Song Gao <gaosong@loongson.cn> Message-ID: <20250714015446.746163-1-maobibo@loongson.cn> Signed-off-by: Song Gao <gaosong@loongson.cn>
