2025-07-21functional: always enable all python warningsDaniel P. Berrangé1-0/+4
Of most importance is that this gives us a heads-up if anything we rely on has been deprecated. The default python behaviour only emits a warning if triggered from __main__ which is very limited.

2025-07-21hw/net/npcm_gmac.c: Drop 'buf' local variablePeter Maydell1-8/+4
We use the local variable 'buf' only when we call dma_memory_read(), and it is always set to &tx_send_buffer[prev_buf_size] immediately before both of those calls. So remove the variable and pass tx_send_buffer + prev_buf_size to dma_memory_read(). This fixes in passing a place where we set buf = tx_send_buffer but never used that value because we always updated buf to something else later before using it.

2025-07-21hw/net/npcm_gmac.c: Correct test for when to reallocate packet bufferPeter Maydell1-2/+2
In gmac_try_send_next_packet() we have code that does "if this block of data won't fit in the buffer, reallocate it". However, the condition it uses is if ((prev_buf_size + tx_buf_len) > sizeof(buf)) where buf is a uint8_t *. This means that sizeof(buf) is always 8 bytes, and the condition will almost always be true, so we will reallocate the buffer more often than we need to. Correct the condition to test against tx_buffer_size, which is where we track how big the allocated buffer is.

2025-07-21hw/net/npcm_gmac.c: Unify length and prev_buf_size variablesPeter Maydell1-4/+5
After the bug fix in the previous commit, the length and prev_buf_size variables are identical, except that prev_buf_size is uint32_t and length is uint16_t. We can therefore unify them. The only place where the type makes a difference is that we will truncate the packet at 64K when sending it; this commit preserves that behaviour by using a local variable when doing the packet send.

2025-07-21hw/net/npcm_gmac.c: Send the right data for second packet in a rowPeter Maydell1-0/+1
The transmit loop in gmac_try_send_next_packet() is constructed in a way that means it will send incorrect data if it it sends more than one packet. The function assembles the outbound data in a dynamically allocated block of memory which is pointed to by tx_send_buffer. We track the first point in this block of memory which is not yet used with the prev_buf_size offset, initially zero. We track the size of the packet we're sending with the length variable, also initially zero. As we read chunks of data out of guest memory, we write them to tx_send_buffer[prev_buf_size], and then increment both prev_buf_size and length. (We might dynamically reallocate the buffer if needed.) When we send a packet, we checksum and send length bytes, starting at tx_send_buffer, and then we reset length to 0. This gives the right data for the first packet. But we don't reset prev_buf_size. This means that if we process more descriptors with further data for the next packet, that data will continue to accumulate at offset prev_buf_size, i.e. after the data for the first packet. But when we transmit that second packet, we send length bytes from tx_send_buffer, so we will send a packet which has the length of the second packet but the data of the first one. The fix for this is to also clear prev_buf_size after the packet has been sent -- we never need the data from packet one after we've sent it, so we can write packet two's data starting at the beginning of the buffer.

2025-07-21tap: fix net_init_tap() return codeSteve Sistare1-2/+2
net_init_tap intends to return 0 for success and -1 on error. However, when net_init_tap() succeeds for a multi-queue device, it returns 1, because of this code where ret becomes 1 when g_unix_set_fd_nonblocking succeeds: ret = g_unix_set_fd_nonblocking(fd, true, NULL); if (!ret) { ... error ... free_fail: ... return ret; Luckily, the only current call site checks for negative, rather than non-zero: net_client_init1() if (net_client_init_fun[](...) < 0) Also, in the unlikely case that g_unix_set_fd_nonblocking fails and returns false, ret=0 is returned, and net_client_init1 will use a broken interface. Fix it to be future proof. Signed-off-by: Steve Sistare <steven.sistare@oracle.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

2025-07-17target/i386: do not expose ARCH_CAPABILITIES on AMD CPUPaolo Bonzini1-1/+5
KVM emulates the ARCH_CAPABILITIES on x86 for both Intel and AMD cpus, although the IA32_ARCH_CAPABILITIES MSR is an Intel-specific MSR and it makes no sense to emulate it on AMD. As a consequence, VMs created on AMD with qemu -cpu host and using KVM will advertise the ARCH_CAPABILITIES feature and provide the IA32_ARCH_CAPABILITIES MSR. This can cause issues (like Windows BSOD) as the guest OS might not expect this MSR to exist on such cpus (the AMD documentation specifies that ARCH_CAPABILITIES feature and MSR are not defined on the AMD architecture). A fix was proposed in KVM code, however KVM maintainers don't want to change this behavior that exists for 6+ years and suggest changes to be done in QEMU instead. Therefore, hide the bit from "-cpu host": migration of -cpu host guests is only possible between identical host kernel and QEMU versions, therefore this is not a problematic breakage. If a future AMD machine does include the MSR, that would re-expose the Windows guest bug; but it would not be KVM/QEMU's problem at that point, as we'd be following a genuine physical CPU impl.

2025-07-16python: fix editable installs for modern pip/setuptoolsJohn Snow1-2/+2
The way editable installs work has changed at some point since Fedora 40 was released. Generally, we should be opting to use pyproject.toml installs (PEP517/518) - but those are not fully supported until v61 of setuptools, and CentOS Stream 9 ships v53. Until that time, we can make use of a transitional feature in pip/setuptools to use "legacy" editable installs, which is enough to fix "make check-dev" on modern local workstations for now. By using the environment variable approach to configure pip, we avoid any problems for older versions of pip that don't recognize this option, so it's harmless. The config-settings option first appeared in v23 of pip. editable_mode was first supported by setuptools in v64. (I'm not currently precisely aware of when the default behavior of '-e' switched away from 'compat', but it appears to be a joint effect between setuptools and pip versions.)

Using qom-list and qom-get to get all the nodes and property values in a QOM tree can take multiple seconds because it requires 1000's of individual QOM requests. Some managers fetch the entire tree or a large subset of it when starting a new VM, and this cost is a substantial fraction of start up time. Define the qom-list-get command, which fetches all the properties and values for a list of paths. This can be much faster than qom-list plus qom-get.

cvtnum() expects input string to specify some sort of size (optionally with KMG... suffix). However, there are a lot of other number conversions in there (using qemu_strtol &Co), also, not all conversions which use cvtnum, actually expects size, - like dd count=nn. Add bool is_size argument to cvtnum() to specify if it should treat the argument as a size or something else, - this changes conversion routine in use and error text. Use the new cvtnum() in more places (like where strtol were used), since it never return negative number in successful conversion. When it makes sense, also specify upper or lower bounds at the same time. This simplifies option processing in multiple places, removing the need of local temporary variables and longer error reporting code. While at it, fix errors, like depth in measure must be >= 1, while the previous code allowed it to be 0. In a few places, change unsigned variables (like of type size_t) to be signed instead, - to avoid the need of temporary conversion variable. All these variables are okay to be signed, we never assign <0 value to them except of the cases of conversion error, where we return immediately. While at it, remove allowed size suffixes from the error message as it makes no sense most of the time (should be in help instead).

2025-07-15qemu-img: implement short --help, remove global help() functionMichael Tokarev1-141/+73
now once all individual subcommands has --help support, remove the large unreadable help() thing and replace it with small global --help, which refers to individual command --help for more info. While at it, also line-wrap list of formats after 75 chars. Since missing_argument() and unrecognized_option() are now unused, remove them.

2025-07-15qemu-img: resize: do not always eat last argumentMichael Tokarev1-14/+27
'qemu-img resize --help' does not work, since it wants more arguments. Also -size is only recognized as a very last argument, but it is common for tools to handle other options after positional arguments too. Tell getopt_long() to return non-options together with options, and process filename and size in the loop, and check if there's an argument right after filename which looks like -N (number), and treat it as size (decrement). This way we can handle --help, and we can also have options after filename and size, and `--' will be handled fine too. The only case which is not handled right is when there's an option between filename and size, and size is given as decrement, - in this case -size will be treated as option, not as size.
