2021-11-02util: Make some iova_tree parameters constEugenio Pérez1-6/+6
As qemu guidelines: Unless a pointer is used to modify the pointed-to storage, give it the "const" attribute. In the particular case of iova_tree_find it allows to enforce what is requested by its comment, since the compiler would shout in case of modifying or freeing the const-qualified returned pointer.

2021-09-27qapi: Convert simple union SocketAddressLegacy to flat oneMarkus Armbruster1-4/+4
Simple unions predate flat unions. Having both complicates the QAPI schema language and the QAPI generator. We haven't been using simple unions in new code for a long time, because they are less flexible and somewhat awkward on the wire. To prepare for their removal, convert simple union SocketAddressLegacy to an equivalent flat one, with existing enum SocketAddressType replacing implicit enum type SocketAddressLegacyKind. Adds some boilerplate to the schema, which is a bit ugly, but a lot easier to maintain than the simple union feature. Cc: "Daniel P.

2021-09-15util: Remove redundant checks in the openpty()AlexChen1-4/+3
As we can see from the following function call stack, amaster and aslave can not be NULL: char_pty_open() -> qemu_openpty_raw() -> openpty(). In addition, according to the API specification for openpty(): https://www.gnu.org/software/libc/manual/html_node/Pseudo_002dTerminal-Pairs.html, the arguments name, termp and winp can all be NULL, but arguments amaster or aslave can not be NULL. Finally, amaster and aslave has been dereferenced at the beginning of the openpty(). So the checks on amaster and aslave in the openpty() are redundant. Remove them.

2021-09-06qemu-sockets: fix unix socket path copy (again)Michael Tokarev1-8/+5
Commit 4cfd970ec188558daa6214f26203fe553fb1e01f added an assert which ensures the path within an address of a unix socket returned from the kernel is at least one byte and does not exceed sun_path buffer. Both of this constraints are wrong: A unix socket can be unnamed, in this case the path is completely empty (not even \0) And some implementations (notable linux) can add extra trailing byte (\0) _after_ the sun_path buffer if we passed buffer larger than it (and we do). So remove the assertion (since it causes real-life breakage) but at the same time fix the usage of sun_path. Namely, we should not access sun_path[0] if kernel did not return it at all (this is the case for unnamed sockets), and use the returned salen when copyig actual path as an upper constraint for the amount of bytes to copy - this will ensure we wont exceed the information provided by the kernel, regardless whenever there is a trailing \0 or not. This also helps with unnamed sockets. Note the case of abstract socket, the sun_path is actually a blob and can contain \0 characters, - it should not be passed to g_strndup and the like, it should be accessed by memcpy-like functions.

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.

When there are in queue a number of requests equal to `aio-max-batch`, the engine invokes the system call to forward the requests to the kernel. This parameter allows us to control the maximum batch size to reduce the latency that requests might accumulate while queued in the AIO engine queue.

2021-07-09meson: fix missing preprocessor symbolsPaolo Bonzini1-1/+1
While most libraries do not need a CONFIG_* symbol because the "when:" clauses are enough, some do. Add them back or stop using them if possible. In the case of libpmem, the statement to add the CONFIG_* symbol was still in configure, but could not be triggered because it checked for "no" instead of "disabled" (and it would be wrong anyway since the test for the library has not been done yet).

2021-07-06Deprecate pmem=on with non-DAX capable backend fileIgor Mammedov1-0/+2
It is not safe to pretend that emulated NVDIMM supports persistence while backend actually failed to enable it and used non-persistent mapping as fall back. Instead of falling-back, QEMU should be more strict and error out with clear message that it's not supported. So if user asks for persistence (pmem=on), they should store backing file on NVDIMM.
