Some qemu updates for IPMI and I2C Move some ADC file to where they belong and move some sensors to a sensor directory, since with new BMCs coming in lots of different sensors should be coming in. Keep from cluttering things up. Add support for I2C PMBus devices. Replace the confusing and error-prone i2c_send_recv and i2c_transfer with specific send and receive functions. Several errors have already been made with these, avoid any new errors. Fix the watchdog_expired field in the IPMI watchdog, it's not a bool, it's a u8. After a vmstate transfer, the new value could be wrong. # gpg: Signature made Fri 09 Jul 2021 17:25:04 BST # gpg: using RSA key FD0D5CE67CE0F59A6688268661F38C90919BFF81 # gpg: Good signature from "Corey Minyard <cminyard@mvista.com>" [unknown] # gpg: aka "Corey Minyard <minyard@acm.org>" [unknown] # gpg: aka "Corey Minyard <corey@minyard.net>" [unknown] # gpg: aka "Corey Minyard <minyard@mvista.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: FD0D 5CE6 7CE0 F59A 6688 2686 61F3 8C90 919B FF81 * remotes/cminyard/tags/for-qemu-6.1-2: (24 commits) tests/qtest: add tests for MAX34451 device model hw/misc: add MAX34451 device tests/qtest: add tests for ADM1272 device model hw/misc: add ADM1272 device hw/i2c: add support for PMBus ipmi/sim: fix watchdog_expired data type error in IPMIBmcSim struct hw/i2c: Introduce i2c_start_recv() and i2c_start_send() hw/i2c: Extract i2c_do_start_transfer() from i2c_start_transfer() hw/i2c: Make i2c_start_transfer() direction argument a boolean hw/i2c: Rename i2c_set_slave_address() -> i2c_slave_set_address() hw/i2c: Remove confusing i2c_send_recv() hw/misc/auxbus: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/misc/auxbus: Replace 'is_write' boolean by its value hw/misc/auxbus: Explode READ_I2C / WRITE_I2C_MOT cases hw/misc/auxbus: Fix MOT/classic I2C mode hw/i2c/ppc4xx_i2c: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/i2c/ppc4xx_i2c: Add reference to datasheet hw/display/sm501: Replace i2c_send_recv() by i2c_recv() & i2c_send() hw/display/sm501: Simplify sm501_i2c_write() logic hw/input/lm832x: Define TYPE_LM8323 in public header ...

Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F), we deprecated the ability to create a file with a backing image that requires qemu to perform format probing. Qemu can still probe older files for backwards compatibility, but it is time to finish off the ability to create such images, due to the potential security risk they present.

2021-07-09export/fuse: Add allow-other optionMax Reitz
Without the allow_other mount option, no user (not even root) but the one who started qemu/the storage daemon can access the export. Allow users to configure the export such that such accesses are possible. While allow_other is probably what users want, we cannot make it an unconditional default, because passing it is only possible (for non-root users) if the global fuse.conf configuration file allows it. Thus, the default is an 'auto' mode, in which we first try with allow_other, and then fall back to without. FuseExport.allow_other reports whether allow_other was actually used as a mount option or not. Currently, this information is not used, but a future patch will let this field decide whether e.g. an export's UID and GID can be changed through chmod. One notable thing about 'auto' mode is that libfuse may print error messages directly to stderr, and so may fusermount (which it executes). Our export code cannot really filter or hide them. Therefore, if 'auto' fails its first attempt and has to fall back, fusermount will print an error message that mounting with allow_other failed. This behavior necessitates a change to iotest 308, namely we need to filter out this error message (because if the first attempt at mounting with allow_other succeeds, there will be no such message). Furthermore, common.rc's _make_test_img should use allow-other=off for FUSE exports, because iotests generally do not need to access images from other users, so allow-other=on or allow-other=auto have no advantage. OTOH, allow-other=on will not work on systems where user_allow_other is disabled, and with allow-other=auto, we get said error message that we would need to filter out again. Just disabling allow-other is simplest. Signed-off-by: Max Reitz <mreitz@redhat.com> Message-Id: <20210625142317.271673-3-mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2021-07-09export/fuse: Pass default_permissions for mountMax Reitz
We do not do any permission checks in fuse_open(), so let the kernel do them. We already let fuse_getattr() report the proper UNIX permissions, so this should work the way we want. This causes a change in 308's reference output, because now opening a non-writable export with O_RDWR fails already, instead of only actually attempting to write to it. (That is an improvement.)

2021-07-09spapr: Implement Open Firmware client interfaceAlexey Kardashevskiy
The PAPR platform describes an OS environment that's presented by a combination of a hypervisor and firmware. The features it specifies require collaboration between the firmware and the hypervisor. Since the beginning, the runtime component of the firmware (RTAS) has been implemented as a 20 byte shim which simply forwards it to a hypercall implemented in qemu. The boot time firmware component is SLOF - but a build that's specific to qemu, and has always needed to be updated in sync with it. Even though we've managed to limit the amount of runtime communication we need between qemu and SLOF, there's some, and it has become increasingly awkward to handle as we've implemented new features. This implements a boot time OF client interface (CI) which is enabled by a new "x-vof" pseries machine option (stands for "Virtual Open Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall which implements Open Firmware Client Interface (OF CI). This allows using a smaller stateless firmware which does not have to manage the device tree. The new "vof.bin" firmware image is included with source code under pc-bios/. It also includes RTAS blob. This implements a handful of CI methods just to get -kernel/-initrd working. In particular, this implements the device tree fetching and simple memory allocator - "claim" (an OF CI memory allocator) and updates "/memory@0/available" to report the client about available memory. This implements changing some device tree properties which we know how to deal with, the rest is ignored. To allow changes, this skips fdt_pack() when x-vof=on as not packing the blob leaves some room for appending. In absence of SLOF, this assigns phandles to device tree nodes to make device tree traversing work. When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree. This adds basic instances support which are managed by a hash map ihandle -> [phandle]. Before the guest started, the used memory is: 0..e60 - the initial firmware 8000..10000 - stack 400000.. - kernel 3ea0000.. - initramdisk This OF CI does not implement "interpret". Unlike SLOF, this does not format uninitialized nvram. Instead, this includes a disk image with pre-formatted nvram. With this basic support, this can only boot into kernel directly. However this is just enough for the petitboot kernel and initradmdisk to boot from any possible source. Note this requires reasonably recent guest kernel with: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=df5be5be8735 The immediate benefit is much faster booting time which especially crucial with fully emulated early CPU bring up environments. Also this may come handy when/if GRUB-in-the-userspace sees light of the day. This separates VOF and sPAPR in a hope that VOF bits may be reused by other POWERPC boards which do not support pSeries. This assumes potential support for booting from QEMU backends such as blockdev or netdev without devices/drivers used.

2021-07-06block: Add backend_defaults propertyAkihiko Odaki
backend_defaults property allow users to control if default block properties should be decided with backend information. If it is off, any backend information will be discarded, which is suitable if you plan to perform live migration to a different disk backend.

By default, it is auto, which uses backend information for block sizes and ignores the others, which is consistent with the older versions.

2021-07-05util/async: add a human-readable name to BHs for debuggingStefan Hajnoczi
It can be difficult to debug issues with BHs in production environments. Although BHs can usually be identified by looking up their ->cb() function pointer, this requires debug information for the program. It is also not possible to print human-readable diagnostics about BHs because they have no identifier. This patch adds a name to each BH. The name is not unique per instance but differentiates between cb() functions, which is usually enough. It's done by changing aio_bh_new() and friends to macros that stringify cb. The next patch will use the name field when reporting leaked BHs.

When the x-blockdev-reopen was added it allowed reconfiguring the graph by replacing backing files, but changing the 'file' option was forbidden. Because of this restriction some operations are not possible, notably inserting and removing block filters. This patch adds support for replacing the 'file' option. This is similar to replacing the backing file and the user is likewise responsible for the correctness of the resulting graph, otherwise this can lead to data corruption.

2021-06-29block: BDRV_O_NO_IO for backing file on creationMax Reitz
When creating an image file with a backing file, we generally try to open the backing file (unless -u was specified), mostly to verify that it is there, but also to get the file size if none was specified for the new image. For neither of these things do we need data I/O, and so we can pass BDRV_O_NO_IO when opening the backing file. This allows us to open even encrypted backing images without requiring the user to provide a secret. This makes the -u switch in iotests 189 and 198 unnecessary (and the $size parameter), so drop it, because this way we get regression tests for this patch here.
