2021-08-05chardev: fix qemu_chr_open_fd() with fd_in==fd_outMarc-André Lureau1-4/+15
The "serial" chardev calls qemu_chr_open_fd() with the same fd. This may lead to double-close as each QIOChannel owns the fd. Instead, share the reference to the same QIOChannel. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>
2021-08-05chardev: fix qemu_chr_open_fd() being called with fd=-1Marc-André Lureau1-9/+17
The "file" chardev may call qemu_chr_open_fd() with fd_in=-1. This may cause invalid system calls, as the QIOChannel is assumed to be properly initialized later on. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>

2021-08-05chardev: mark explicitly first argument as poisonedMarc-André Lureau12-13/+19
Since commit 9894dc0cdcc397ee5b26370bc53da6d360a363c2 "char: convert from GIOChannel to QIOChannel", the first argument to the watch callback can actually be a QIOChannel, which is not a GIOChannel (but a QEMU Object). Even though we never used that pointer, change the callback type to warn the users. Possibly a better fix later, we may want to store the callback and call it from intermediary functions.

2021-08-04util: fix abstract socket path copyMarc-André Lureau1-1/+4
Commit 776b97d360 "qemu-sockets: add abstract UNIX domain socket support" neglected to update socket_sockaddr_to_address_unix() and copied the whole sun_path without taking "salen" into account. Later, commit 3b14b4ec49 "sockets: Fix socket_sockaddr_to_address_unix() for abstract sockets" handled the abstract UNIX path, by stripping the leading \0 character and fixing address details, but didn't use salen either. Not taking "salen" into account may result in incorrect "path" being returned in monitors commands, as we read past the address which is not necessarily \0-terminated.

2021-08-03Revert "acpi/gpex: Inform os to keep firmware resource map"Michael S. Tsirkin1-18/+2
This reverts commit 0cf8882fd06ba0aeb1e90fa6f23fce85504d7e14. Which this commit, with aarch64 when using efi PCI devices with IO ports do not work. The reason is that EFI creates I/O port mappings below 0x1000 (in fact, at 0). However Linux, for legacy reasons, does not support I/O ports <= 0x1000 on PCI, so the I/O assignment created by EFI is rejected. EFI creates the mappings primarily for itself, and up until DSM #5 started to be enforced, all PCI resource allocations that existed at boot were ignored by Linux and recreated from scratch. Also, the commit in question looks dubious - it seems unlikely that Linux would fail to create a resource tree. What does happen is that BARs get moved around, which may cause trouble in some cases: for instance, Linux had to add special code to the EFI framebuffer driver to copy with framebuffer BARs being relocated. DSM #5 has a long history of debate and misinterpretation.

2021-08-03acpi: x86: pcihp: add support hotplug on multifunction bridgesIgor Mammedov1-14/+30
Commit [1] switched PCI hotplug from native to ACPI one by default.

Technically there is no reason not to describe cold-plugged bridges (root ports) on functions other then 0, as they similarly to bridge on function 0 are unpluggable. So since we need to describe multifunction devices iterate over fuctions as well. But describe only cold-plugged bridges[root ports] on functions other than 0 as well. 1) Fixes: 17858a169508609ca9063c544833e5a1adeb7b52 (hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reported-by: Laurent Vivier <lvivier@redhat.com> Message-Id: <20210723090424.2092226-1-imammedo@redhat.com> Fixes: 17858a169508609ca9063c544833e5a1adeb7b52 (hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35)<br> Signed-off-by: Igor Mammedov &lt;<a href="mailto:imammedo@redhat.com" target="_blank">imammedo@redhat.com</a>&gt;<br> Reported-by: Laurent Vivier &lt;<a href="mailto:lvivier@redhat.com" target="_blank">lvivier@redhat.com</a>&gt;<br> Reviewed-by: Michael S.

2021-08-03hw/pcie-root-port: Fix hotplug for PCI devices requiring IOMarcel Apfelbaum1-0/+5
Q35 has now ACPI hotplug enabled by default for PCI(e) devices. As opposed to native PCIe hotplug, guests like Fedora 34 will not assign IO range to pcie-root-ports not supporting native hotplug, resulting into a regression. Reproduce by: qemu-bin -M q35 -device pcie-root-port,id=p1 -monitor stdio device_add e1000,bus=p1 In the Guest OS the respective pcie-root-port will have the IO range disabled. Fix it by setting the "reserve-io" hint capability of the pcie-root-ports so the firmware will allocate the IO range instead.

2021-08-03block: Fix in_flight leak in request padding error pathKevin Wolf1-3/+4
When bdrv_pad_request() fails in bdrv_co_preadv_part(), bs->in_flight has been increased, but is never decreased again. This leads to a hang when trying to drain the block node. This bug was observed with Windows guests which issue a request that fully uses IOV_MAX during installation, so that when padding is necessary (O_DIRECT with a 4k sector size block device on the host), adding another entry causes failure. Call bdrv_dec_in_flight() to fix this. There is a larger problem to solve here because this request shouldn't even fail, but Windows doesn't seem to care and with this minimal fix the installation succeeds. So given that we're already in freeze, let's take this minimal fix for 6.1.

2021-08-03linux-user/s390x: signal with SIGFPE on compare-and-trapJonathan Albrecht1-20/+34
Currently when a compare-and-trap instruction is executed, qemu will always raise a SIGILL signal. On real hardware, a SIGFPE is raised. Change the PGM_DATA case in cpu_loop to follow the behavior in linux kernel /arch/s390/kernel/traps.c. * Only raise SIGILL if DXC == 0 * If DXC matches a non-simulated IEEE exception, raise SIGFPE with correct si_code * Raise SIGFPE with si_code == 0 for everything else When applied on 20210705210434.45824-2-iii@linux.ibm.com, this fixes crashes in the java jdk such as the linked bug.

For SIGILL, SIGFPE and SIGTRAP the PSW must point after the instruction, and at the instruction for other signals. Currently under qemu-user for SIGFILL and SIGFPE it points at the instruction. Fix by advancing psw.addr for these signals.

2021-08-03qga-win/msi: fix missing libstdc++-6 DLL in MSI installerMichael Roth1-0/+4
libstdc++ is required for the qga-vss.dll that provides fsfreeze functionality. Currently it is not provided by the MSI installer, resulting in fsfreeze being disabled in guest environments where it has not been installed by other means. In the future this would be better handled via gcc-cpp ComponentGroup provided by msitools, but that would be better handled with a general rework of DLL dependency handling in the installer build. Keep it simple for now to fix this regression. Tested with Fedora 34 mingw build environment.

2021-08-02hw/arm/boot: Report error if there is no fw_cfg device in the machinePeter Maydell2-7/+9
If the user provides both a BIOS/firmware image and also a guest kernel filename, arm_setup_firmware_boot() will pass the kernel image to the firmware via the fw_cfg device. However we weren't checking whether there really was a fw_cfg device present, and if there wasn't we would crash. This crash can be provoked with a command line such as qemu-system-aarch64 -M raspi3 -kernel /dev/null -bios /dev/null -display none It is currently only possible on the raspi3 machine, because unless the machine sets info->firmware_loaded we won't call arm_setup_firmware_boot(), and the only machines which set that are: * virt (has a fw-cfg device) * sbsa-ref (checks itself for kernel_filename && firmware_loaded) * raspi3 (crashes) But this is an unfortunate beartrap to leave for future machine model implementors, so we should handle this situation in boot.c. Check in arm_setup_firmware_boot() whether the fw-cfg device exists before trying to load files into it, and if it doesn't exist then exit with a hopefully helpful error message. Because we now handle this check in a machine-agnostic way, we can remove the check from sbsa-ref.

The default "role" if none is specified is "title_reference", intended for references to book or article titles, and it renders into the HTML as <cite>...</cite> (usually comes out as italics).
