2024-10-31target/i386/hvf: fix handling of XSAVE-related CPUID bitsPaolo Bonzini
The call to xgetbv() is passing the ecx value for cpuid function 0xD, index 0. The xgetbv call thus returns false (OSXSAVE is bit 27, which is well out of the range of CPUID[0xD,0].ECX) and eax is not modified. While fixing it, cache the whole computation of supported XCR0 bits since it will be used for more than just CPUID leaf 0xD. Furthermore, unsupported subleafs of CPUID 0xD (including all those corresponding to zero bits in host's XCR0) must be hidden; if OSXSAVE is not set at all, the whole of CPUID leaf 0xD plus the XSAVE bit must be hidden. Finally, unconditionally drop XSTATE_BNDREGS_MASK and XSTATE_BNDCSR_MASK; real hardware will only show them if the MPX bit is set in CPUID; this is never the case for hvf_get_supported_cpuid() because QEMU's Hypervisor.framework support does not handle the VMX fields related to MPX (even in the unlikely possibility that the host has MPX enabled). So hide those bits in the new cache_host_xcr0(). Cc: Phil Dennis-Jordan <lists@philjordan.eu> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2024-10-22util: Add RISC-V vector extension probe in cpuinfoTANG Tiancheng
Add support for probing RISC-V vector extension availability in the backend. This information will be used when deciding whether to use vector instructions in code generation. Cache lg2(vlenb) for the backend. The storing of lg2(vlenb) means we can convert all of the division into subtraction. While the compiler doesn't support RISCV_HWPROBE_EXT_ZVE64X, we use RISCV_HWPROBE_IMA_V instead. RISCV_HWPROBE_IMA_V is more strictly constrainted than RISCV_HWPROBE_EXT_ZVE64X. At least in current QEMU implemenation, the V vector extension depends on the zve64d extension.

2024-10-22util: don't set SO_REUSEADDR on client socketsDaniel P. Berrangé
Setting the SO_REUSEADDR property on a socket allows binding to a port number that is in the TIMED_WAIT state. This is usually done on listener sockets, to enable a server to restart itself without having to wait for the completion of TIMED_WAIT on the port. It is also possible, but highly unusual, to set it on client sockets. It is rare to explicitly bind() a client socket, since it is almost always fine to allow the kernel to auto-bind a client socket to a random free port. Most systems will have many 10's of 1000's of free ports that client sockets will be bound to. eg on Linux $ sysctl -a | grep local_port net.ipv4.ip_local_port_range = 32768 60999 eg on OpenBSD $ sysctl -a | grep net.inet.ip.port net.inet.ip.portfirst=1024 net.inet.ip.portlast=49151 net.inet.ip.porthifirst=49152 net.inet.ip.porthilast=65535 A connected socket must have a unique set of value for (protocol, localip, localport, remoteip, remoteport) otherwise it is liable to get EADDRINUSE. A client connection should trivially avoid EADDRINUSE if letting the kernel auto-assign the 'localport' value, which QEMU always does. When QEMU sets SO_REUSEADDR on a client socket on OpenBSD, however, it upsets this situation. The OpenBSD kernel appears to happily pick a 'localport' that is in the TIMED_WAIT state, even if there are many other available local ports available for use that are not in the TIMED_WAIT state. A test program that just loops opening client sockets will start seeing EADDRINUSE on OpenBSD when as few as 2000 ports are in TIMED_WAIT, despite 10's of 1000's ports still being unused. This contrasts with Linux which appears to avoid picking local ports in TIMED_WAIT state. This problem on OpenBSD exhibits itself periodically with the migration test failing with a message like[1]: qemu-system-ppc64: Failed to connect to '127.0.0.1:24109': Address already in use While I have not been able to reproduce the OpenBSD failure in my own testing, given the scope of what QEMU tests do, it is entirely possible that there could be a lot of ports in TIMED_WAIT state when the migration test runs. Removing SO_REUSEADDR from the client sockets should not affect normal QEMU usage, and should improve reliability on OpenBSD. This use of SO_REUSEADDR on client sockets is highly unusual, and appears to have been present since the very start of the QEMU socket helpers in 2008. The orignal commit has no comment about the use of SO_REUSEADDR on the client, so is most likely just an 16 year old copy+paste bug.

2024-10-18block: Improve errors about block sizesMarkus Armbruster
Block sizes need to be a power of two between 512 and an arbitrary limit, currently 2MiB. Commit 5937835ac4c factored block size checking out of set_blocksize() into new check_block_size(), for reuse in block/export/. Its two error messages are okay for the original purpose: $ qemu-system-x86_64 -device ide-hd,physical_block_size=1 qemu-system-x86_64: -device ide-hd,physical_block_size=1: Property .physical_block_size doesn't take value 1 (minimum: 512, maximum: 2097152) $ qemu-system-x86_64 -device ide-hd,physical_block_size=513 qemu-system-x86_64: -device ide-hd,physical_block_size=513: Property .physical_block_size doesn't take value '513', it's not a power of 2 They're mildly off for block exports: $ qemu-storage-daemon --blockdev node-name=nod0,driver=file,filename=foo.img --export type=vduse-blk,id=exp0,node-name=nod0,name=foo,logical-block-size=1 qemu-storage-daemon: --export type=vduse-blk,id=exp0,node-name=nod0,name=foo,logical-block-size=1: Property exp0.logical-block-size doesn't take value 1 (minimum: 512, maximum: 2097152) The error message talks about a property. CLI options like --export don't have properties, they have parameters. Replace the two error messages by a single one that's okay for both purposes. Looks like this: qemu-storage-daemon: --export type=vduse-blk,id=exp0,node-name=nod0,name=foo,logical-block-size=1: parameter logical-block-size must be a power of 2 between 512 and 2097152 Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-ID: <20241010150144.986655-3-armbru@redhat.com> Reviewed-by: Daniel P.

2024-10-15include: Move QemuLockCnt APIs to their own headerPeter Maydell
Currently the QemuLockCnt data structure and associated functions are in the include/qemu/thread.h header. Move them to their own qemu/lockcnt.h. The main reason for doing this is that it means we can autogenerate the documentation comments into the docs/devel documentation. The copyright/author in the new header is drawn from lockcnt.c, since the header changes were added in the same commit as lockcnt.c; since neither thread.h nor lockcnt.c state an explicit license, the standard default of GPL-2-or-later applies. We include the new header (and the .c file, which was accidentally omitted previously) in the "RCU" part of MAINTAINERS, since that is where the lockcnt.rst documentation is categorized.

2024-09-10qapi/crypto: Rename QCryptoHashAlgorithm to *Algo, and drop prefixMarkus Armbruster
QAPI's 'prefix' feature can make the connection between enumeration type and its constants less than obvious. It's best used with restraint. QCryptoHashAlgorithm has a 'prefix' that overrides the generated enumeration constants' prefix to QCRYPTO_HASH_ALG. We could simply drop 'prefix', but then the prefix becomes QCRYPTO_HASH_ALGORITHM, which is rather long. We could additionally rename the type to QCryptoHashAlg, but I think the abbreviation "alg" is less than clear. Rename the type to QCryptoHashAlgo instead. The prefix becomes to QCRYPTO_HASH_ALGO.

2024-07-25util/async.c: Forbid negative min/max in aio_context_set_thread_pool_params()Peter Maydell
aio_context_set_thread_pool_params() takes two int64_t arguments to set the minimum and maximum number of threads in the pool. We do some bounds checking on these, but we don't catch the case where the inputs are negative. This means that later in the function when we assign these inputs to the AioContext::thread_pool_min and ::thread_pool_max fields, which are of type int, the values might overflow the smaller type. A negative number of threads is meaningless, so make aio_context_set_thread_pool_params() return an error if either min or max are negative.

2024-07-23util/fifo8: Rename fifo8_peek_buf() -> fifo8_peek_bufptr()Philippe Mathieu-Daudé
Since fifo8_peek_buf() return a const buffer (which points directly into the FIFO backing store). Rename it using the 'bufptr' suffix to better reflect that it is a pointer to the internal buffer that is being returned. This will help differentiate with methods *copying* the FIFO data.
