Main purpose of this API is to get rid of error prone individual array deallocation pathes in user code, i.e. turning something like this: void doSomething(size_t n) { Foo *foos = malloc(n * sizeof(Foo)); for (...) { foos[i].s = malloc(...); if (...) { goto out; } } out: if (...) { for (...) { /* deep deallocation */ free(foos[i].s); } /* array deallocation */ free(foos); } } into something more simple and safer like: void doSomething(size_t n) { P9ARRAY_REF(Foo) foos = NULL; P9ARRAY_NEW(Foo, foos, n); for (...) { foos[i].s = malloc(...); if (...) { return; /* array auto freed here */ } } /* array auto freed here */ } Unlike GArray, P9Array does not require special macros, function calls or struct member dereferencing to access the individual array elements: C-array = P9Array: vs. GArray: for (...) { | for (...) { ... = arr[i].m; | ... = g_array_index(arr, Foo, i).m; arr[i].m = ... ; | g_array_index(arr, Foo, i).m = ... ; } | } So existing C-style array code can be retained with only very little changes; basically limited to replacing array allocation call and of course removing individual array deallocation pathes. In this initial version P9Array only supports the concept of unique pointers, i.e. it does not support reference counting. The array (and all dynamically allocated memory of individual array elements) is auto freed once execution leaves the scope of the reference variable (unique pointer) associated with the array. Internally a flex array struct is used in combination with macros spanned over a continuous memory space for both the array's meta data (private) and the actual C-array user data (public): struct P9Array##scalar_type { size_t len; /* private, hidden from user code */ scalar_type first[]; /* public, directly exposed to user code */ }; Which has the advantage that the compiler automatically takes care about correct padding, alignment and overall size for all scalar data types on all systems and that the user space exposed pointer can directly be translated back and forth between user space C-array pointer and internal P9Array struct whenever needed, in a type-safe manner. This header file is released under MIT license, to allow this file being used in other C-projects as well. The common QEMU license GPL2+ might have construed a conflict for other projects.

| * 9pfs: fix wrong I/O block size in RgetattrChristian Schoenebeck2021-10-271-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When client sent a 9p Tgetattr request then the wrong I/O block size value was returned by 9p server; instead of host file system's I/O block size it should rather return an I/O block size according to 9p session's 'msize' value, because the value returned to client should be an "optimum" block size for I/O (i.e. to maximize performance), it should not reflect the actual physical block size of the underlying storage media. The I/O block size of a host filesystem is typically 4k, so the value returned was far too low for good 9p I/O performance. This patch adds stat_to_iounit() with a similar approach as the existing get_iounit() function.

There's a problem, though: query-qmp-schema shows an enum type's members as an array of member names (SchemaInfoEnum member @values). If it showed an array of objects with a name member, we could simply add more members to these objects. Since it's just strings, we can't. I can see three ways to correct this design mistake: 1. Do it the way we should have done it, plus compatibility goo. We want a ['SchemaInfoEnumMember'] member in SchemaInfoEnum. Since changing @values would be a compatibility break, add a new member @members instead. @values is now redundant. In my testing, output of qemu-system-x86_64's query-qmp-schema grows by 11% (18.5KiB). We can deprecate @values now and drop it later. This will break outmoded clients. Well-behaved clients such as libvirt are expected to break cleanly. 2. Like 1, but omit "boring" elements of @member, and empty @member. @values does not become redundant. @members augments it. Somewhat cumbersome, but output of query-qmp-schema grows only as we make enum members non-boring. There is nothing to deprecate here. 3. Versioned query-qmp-schema. query-qmp-schema provides either @values or @members. The QMP client can select which version it wants. There is no redundant output. We can deprecate old versions and eventually drop them. This will break outmoded clients. Breaking cleanly is easier than for 1. While 1 and 2 operate within the common rules for compatible evolution apply (section "Compatibility considerations" in docs/devel/qapi-code-gen.rst), 3 bypasses them. Attractive when operating within the rules is just too awkward. Not the case here. This commit implements 1. Libvirt developers prefer it. Deprecate @values in favour of @members. Since query-qmp-schema compatibility is pretty fundamental for management applications, an extended grace period is advised.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | Right now for xattr remapping, we support types of "prefix", "ok" or "bad". Type "bad" returns -EPERM on setxattr and hides xattr in listxattr. For getxattr, mapping code returns -EPERM but getxattr code converts it to -ENODATA. I need a new semantics where if an xattr is unsupported, then getxattr()/setxattr() return -ENOTSUP and listxattr() should hide the xattr. This is needed to simulate that security.selinux is not supported by virtiofs filesystem and in that case client falls back to some default label specified by policy. So add a new type "unsupported" which returns -ENOTSUP on getxattr() and setxattr() and hides xattrs in listxattr(). For example, one can use following mapping rule to not support security.selinux xattr and allow others.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the comment to match what the code is doing, as explained in the changelog of commit 86cf9e154632cb28d749db0ea47946fba8cf3f09 that introduced the change: Commit 9458a9a1df1a4c719e24512394d548c1fc7abd22 added synchronization of vCPU and migration operations through calling run_on_cpu operation. However, in replay mode this synchronization is unneeded, because I/O and vCPU threads are already synchronized. This patch disables such synchronization for record/replay mode.
