2025-05-14vhost-user: return failure if backend crash when live migrationHaoqian He1-1/+2
Live migration should be terminated if the vhost-user backend crashes before the migration completes. Specifically, since the vhost device will be stopped when VM is stopped before the end of the live migration, in current implementation if the backend crashes, vhost-user device set_status() won't return failure, live migration won't perceive the disconnection between QEMU and the backend. When the VM is migrated to the destination, the inflight IO will be resubmitted, and if the IO was completed out of order before, it will cause IO error. To fix this issue: 1. Add the return value to set_status() for VirtioDeviceClass. a. For the vhost-user device, return failure when the backend crashes. b. For other virtio devices, always return 0. 2. Return failure if vhost_dev_stop() failed for vhost-user device. If QEMU loses connection with the vhost-user backend, virtio set_status() can return failure to the upper layer, migration_completion() can handle the error, terminate the live migration, and restore the VM, so that inflight IO can be completed normally.

On Emscripten, function pointer casts can result in runtime failures due to strict function signature checks. This affects the use of g_list_sort and g_slist_sort, which internally perform function pointer casts that are not supported by Emscripten. To avoid these issues, g_list_sort_with_data and g_slist_sort_with_data should be used instead, as they do not rely on function pointer casting.

This reverts commit 7987d2be5a8bc3a502f89ba8cf3ac3e09f64d1ce. The goal was to remove the need to patch the (const) input buffer with a recomputed UDP checksum by copying headers to a RW region and inject the checksum there. The patch computed the checksum only from the header fields (missing the rest of the payload) producing an invalid one and making guests fail to acquire a DHCP lease.

2025-03-11hw/net/smc91c111: Don't allow data register access to overrun bufferPeter Maydell1-12/+53
For accesses to the 91c111 data register, the address within the packet's data frame is determined by a combination of the pointer register and the offset used to access the data register, so that you can access data at effectively wider than byte width. The pointer register's pointer field is 11 bits wide, which is exactly the size to index a 2048-byte data frame. We weren't quite getting the logic right for ensuring that we end up with a pointer value to use in the s->data[][] array that isn't out of bounds: * we correctly mask when getting the initial pointer value * for the "autoincrement the pointer register" case, we correctly mask after adding 1 so that the pointer register wraps back around at the 2048 byte mark * but for the non-autoincrement case where we have to add the low 2 bits of the data register offset, we don't account for the possibility that the pointer register is 0x7ff and the addition should wrap Fix this bug by factoring out the "get the p value to use as an array index" into a function, making it use FIELD macro names rather than hard-coded constants, and having a utility function that does "add a value and wrap it" that we can use both for the "autoincrement" and "add the offset bits" codepaths.

2025-03-11hw/net/smc91c111: Sanitize packet length on txPeter Maydell1-5/+29
When the smc91c111 transmits a packet, it must read a control byte which is at the end of the data area and CRC. However, we don't sanitize the length field in the packet buffer, so if the guest sets the length field to something large we will try to read past the end of the packet data buffer when we access the control byte. As usual, the datasheet says nothing about the behaviour of the hardware if the guest misprograms it in this way. It says only that the maximum valid length is 2048 bytes. We choose to log the guest error and silently drop the packet. This requires us to factor out the "mark the tx packet as complete" logic, so we can call it for this "drop packet" case as well as at the end of the loop when we send a valid packet.

2025-03-11hw/net/smc91c111: Sanitize packet numbersPeter Maydell1-0/+45
The smc91c111 uses packet numbers as an index into its internal s->data[][] array. Valid packet numbers are between 0 and 3, but the code does not generally check this, and there are various places where the guest can hand us an arbitrary packet number and cause an out-of-bounds access to the data array. Add validation of packet numbers. The datasheet is not very helpful about how guest errors like this should be handled: it says nothing on the subject, and none of the documented error conditions are relevant. We choose to log the situation with LOG_GUEST_ERROR and silently ignore the attempted operation. In the places where we are about to access the data[][] array using a packet number and we know the number is valid because we got it from somewhere that has already validated, we add an assert() to document that belief.

2025-02-16hw/net/smc91c111: Ignore attempt to pop from empty RX fifoPeter Maydell1-0/+9
The SMC91C111 includes an MMU Command register which permits the guest to remove entries from the RX FIFO. The datasheet does not specify what happens if the guest tries to do this when the FIFO is already empty; there are no status registers containing error bits which might be applicable. Currently we don't guard at all against pop of an empty RX FIFO, with the result that we allow the guest to drive the rx_fifo_len index to negative values, which will cause smc91c111_receive() to write to the rx_fifo[] array out of bounds when we receive the next packet. Instead ignore attempts to pop an empty RX FIFO.

This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there.

Correct these bugs: * in the !disable_mask codepath, use lduw_le_p() so we correctly load a 16-bit value for comparison * in the disable_mask codepath, we load a full 4-byte value from rx_buf for the comparison, set the compare value to the whole of the cr0 register (i.e. the concatenation of the mask and compare fields), and set mask to 0xffffffff to force a 32-bit comparison Signed-off-by: Andrew Yuan <andrew.yuan@jaguarmicro.com> Message-id: 20241219061658.805-1-andrew.yuan@jaguarmicro.com Suggested-by: Philippe Mathieu-Daudé <philmd@linaro.org> [PMM: Expand commit message and comment] Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.
