2024-03-05linux-user: Remove pgb_dynamic alignment assertionRichard Henderson
The assertion was never correct, because the alignment is a composite of the image alignment and SHMLBA. Even if the image alignment didn't match the image address, an assertion would not be correct -- more appropriate would be an error message about an ill formed image. But the image cannot be held to SHMLBA under any circumstances.

Commit 39fb3cfc28b ("configure: clean up plugin option handling", 2023-10-18) dropped the CONFIG_PLUGIN line from tests/tcg/config-host.mak, due to confusion caused by the shadowing of $config_host_mak. However, TCG tests were still expecting it. Oops. Put it back, in the meanwhile the shadowing is gone so it's clear that it goes in the tests/tcg configuration.

2024-03-01chardev/char-socket: Fix TLS io channels sending too much data to the backendThomas Huth
Commit ffda5db65a ("io/channel-tls: fix handling of bigger read buffers") changed the behavior of the TLS io channels to schedule a second reading attempt if there is still incoming data pending. This caused a regression with backends like the sclpconsole that check in their read function that the sender does not try to write more bytes to it than the device can currently handle. The problem can be reproduced like this: 1) In one terminal, do this: mkdir qemu-pki cd qemu-pki openssl genrsa 2048 > ca-key.pem openssl req -new -x509 -nodes -days 365000 -key ca-key.pem -out ca-cert.pem # enter some dummy value for the cert openssl genrsa 2048 > server-key.pem openssl req -new -x509 -nodes -days 365000 -key server-key.pem \ -out server-cert.pem # enter some other dummy values for the cert gnutls-serv --echo --x509cafile ca-cert.pem --x509keyfile server-key.pem \ --x509certfile server-cert.pem -p 8338 2) In another terminal, do this: wget https://download.fedoraproject.org/pub/fedora-secondary/releases/39/Cloud/s390x/images/Fedora-Cloud-Base-39-1.5.s390x.qcow2 qemu-system-s390x -nographic -nodefaults \ -hda Fedora-Cloud-Base-39-1.5.s390x.qcow2 \ -object tls-creds-x509,id=tls0,endpoint=client,verify-peer=false,dir=$PWD/qemu-pki \ -chardev socket,id=tls_chardev,host=localhost,port=8338,tls-creds=tls0 \ -device sclpconsole,chardev=tls_chardev,id=tls_serial QEMU then aborts after a second or two with: qemu-system-s390x: ../hw/char/sclpconsole.c:73: chr_read: Assertion `size <= SIZE_BUFFER_VT220 - scon->iov_data_len' failed. Aborted (core dumped) It looks like the second read does not trigger the chr_can_read() function to be called before the second read, which should normally always be done before sending bytes to a character device to see how much it can handle, so the s->max_size in tcp_chr_read() still contains the old value from the previous read. Let's make sure that we use the up-to-date value by calling tcp_chr_read_poll() again here.

2024-03-01hw/usb/bus.c: PCAP adding 0xA in Windows versionBenjamin David Lunt
Since Windows text files use CRLFs for all \n, the Windows version of QEMU inserts a CR in the PCAP stream when a LF is encountered when using USB PCAP files. This is due to the fact that the PCAP file is opened as TEXT instead of BINARY. To show an example, when using a very common protocol to USB disks, the BBB protocol uses a 10-byte command packet. For example, the READ_CAPACITY(10) command will have a command block length of 10 (0xA). When this 10-byte command (part of the 31-byte CBW) is placed into the PCAP file, the Windows file manager inserts a 0xD before the 0xA, turning the 31-byte CBW into a 32-byte CBW. Actual CBW: 0040 55 53 42 43 01 00 00 00 08 00 00 00 80 00 0a 25 USBC...........% 0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...............

Python is transitioning to a world where you're not allowed to use 'pip install' outside of a virutal env by default. The rationale is to stop use of pip clashing with distro provided python packages, which creates a major headache on distro upgrades.

2024-02-28tests/vm: avoid re-building the VM images all the timeAlex Bennée
The main problem is that "check-venv" is a .PHONY target will always evaluate and trigger a full re-build of the VM images. While its tempting to drop it from the dependencies that does introduce a breakage on freshly configured builds. Fortunately we do have the otherwise redundant --force flag for the script which up until now was always on. If we make the usage of --force conditional on dependencies other than check-venv triggering the update we can avoid the costly rebuild and still run cleanly on a fresh checkout.

2024-02-28target/i386: remove unnecessary/wrong application of the A20 maskPaolo Bonzini
If ptw_translate() does a MMU_PHYS_IDX access, the A20 mask is already applied in get_physical_address(), which is called via probe_access_full() and x86_cpu_tlb_fill(). If ptw_translate() on the other hand does a MMU_NESTED_IDX access, the A20 mask must not be applied to the address that is looked up in the nested page tables; it must be applied only to the addresses that hold the NPT entries (which is achieved via MMU_PHYS_IDX, per the previous paragraph). Therefore, we can remove A20 masking from the computation of the page table entry's address, and let get_physical_address() or mmu_translate() apply it when they know they are returning a host-physical address.

2024-02-28target/i386: Fix physical address truncationPaolo Bonzini
The address translation logic in get_physical_address() will currently truncate physical addresses to 32 bits unless long mode is enabled. This is incorrect when using physical address extensions (PAE) outside of long mode, with the result that a 32-bit operating system using PAE to access memory above 4G will experience undefined behaviour. The truncation code was originally introduced in commit 33dfdb5 ("x86: only allow real mode to access 32bit without LMA"), where it applied only to translations performed while paging is disabled (and so cannot affect guests using PAE). Commit 9828198 ("target/i386: Add MMU_PHYS_IDX and MMU_NESTED_IDX") rearranged the code such that the truncation also applied to the use of MMU_PHYS_IDX and MMU_NESTED_IDX. Commit 4a1e9d4 ("target/i386: Use atomic operations for pte updates") brought this truncation into scope for page table entry accesses, and is the first commit for which a Windows 10 32-bit guest will reliably fail to boot if memory above 4G is present. The truncation code however is not completely redundant. Even though the maximum address size for any executed instruction is 32 bits, helpers for operations such as BOUND, FSAVE or XSAVE may ask get_physical_address() to translate an address outside of the 32-bit range, if invoked with an argument that is close to the 4G boundary. Likewise for processor accesses, for example TSS or IDT accesses, when EFER.LMA==0. So, move the address truncation in get_physical_address() so that it applies to 32-bit MMU indexes, but not to MMU_PHYS_IDX and MMU_NESTED_IDX.

2024-02-22.gitlab-ci.d/windows.yml: Drop msys2-32bit jobPeter Maydell
MSYS2 is dropping support for 32-bit Windows. This shows up for us as various packages we were using in our CI job no longer being available to install, which causes the job to fail. In commit 8e31b744fdf we dropped the dependency on libusb and spice, but the dtc package has also now been removed. For us as QEMU upstream, "32 bit x86 hosts for system emulation" have already been deprecated as of QEMU 8.0, so we are ready to drop them anyway. Drop the msys2-32bit CI job, as the first step in doing this. This is cc'd to stable, because this job will also be broken for CI on the stable branches. We can't drop 32-bit support entirely there, but we will still be covering at least compilation for 32-bit Windows via the cross-win32-system job.

2024-02-20ui/console: Fix console resize with placeholder surfaceTianlan Zhou
In `qemu_console_resize()`, the old surface of the console is keeped if the new console size is the same as the old one. If the old surface is a placeholder, and the new size of console is the same as the placeholder surface (640*480), the surface won't be replace. In this situation, the surface's `QEMU_PLACEHOLDER_FLAG` flag is still set, so the console won't be displayed in SDL display mode. This patch fixes this problem by forcing a new surface if the old one is a placeholder.

2024-02-20ui/clipboard: mark type as not available when there is no dataFiona Ebner
With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT message with len=0. In qemu_clipboard_set_data(), the clipboard info will be updated setting data to NULL (because g_memdup(data, size) returns NULL when size is 0). If the client does not set the VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then the 'request' callback for the clipboard peer is not initialized. Later, because data is NULL, qemu_clipboard_request() can be reached via vdagent_chr_write() and vdagent_clipboard_recv_request() and there, the clipboard owner's 'request' callback will be attempted to be called, but that is a NULL pointer. In particular, this can happen when using the KRDC (22.12.3) VNC client. Another scenario leading to the same issue is with two clients (say noVNC and KRDC): The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and initializes its cbpeer. The KRDC client does not, but triggers a vnc_client_cut_text() (note it's not the _ext variant)). There, a new clipboard info with it as the 'owner' is created and via qemu_clipboard_set_data() is called, which in turn calls qemu_clipboard_update() with that info. In qemu_clipboard_update(), the notifier for the noVNC client will be called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the noVNC client. The 'owner' in that clipboard info is the clipboard peer for the KRDC client, which did not initialize the 'request' function. That sounds correct to me, it is the owner of that clipboard info. Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it passes), that clipboard info is passed to qemu_clipboard_request() and the original segfault still happens. Fix the issue by handling updates with size 0 differently. In particular, mark in the clipboard info that the type is not available. While at it, switch to g_memdup2(), because g_memdup() is deprecated.

When msys2 updated their libusb packages to libusb 1.0.27, they dropped support for building them for mingw32, leaving only mingw64 packages. This broke our CI job, as the 'pacman' package install now fails with: error: target not found: mingw-w64-i686-libusb error: target not found: mingw-w64-i686-usbredir (both these binary packages are from the libusb source package). Similarly, spice is now 64-bit only: error: target not found: mingw-w64-i686-spice Fix this by dropping these packages from the list we install for our msys2-32bit build. We do this with a simple mechanism for the msys2-64bit and msys2-32bit jobs to specify a list of extra packages to install on top of the common ones we install for both jobs.
