2020-09-06linux-user: Protect btrfs ioctl target definitionsFilip Bozuta
Target definitions of btrfs ioctls in 'syscall_defs.h' use the value BTRFS_IOCTL_MAGIC that is defined header 'btrfs.h'. This header is not available in kernel versions before 3.9. For that reason, these target ioctl definitions should be enwrapped in an #ifdef directive to check whether the 'btrfs.h' header is available as to not cause build errors on older Linux systems.

2020-09-05linux-user: Add support for ppoll_time64() and pselect6_time64()Filip Bozuta
This patch introduces functionality for following time64 syscalls: *ppoll_time64 This is a year 2038 safe variant of: int poll(struct pollfd *fds, nfds_t nfds, int timeout) -- wait for some event on a file descriptor -- man page: https://man7.org/linux/man-pages/man2/ppoll.2.html *pselect6_time64 This is a year 2038 safe variant of: int pselect6(int nfds, fd_set *readfds, fd_set *writefds, fd_set *exceptfds, const struct timespec *timeout, const sigset_t *sigmask); -- synchronous I/O multiplexing -- man page: https://man7.org/linux/man-pages/man2/pselect6.2.html Implementation notes: Year 2038 safe syscalls in this patch were implemented with the same code as their regular variants (ppoll() and pselect()). This code was moved to new functions ('do_ppoll()' and 'do_pselect6()') that take a 'bool time64' from which a right 'struct timespec' converting function is called. (target_to_host/host_to_target_timespec() for regular and target_to_host/host_to_target_timespec64() for time64 variants) Signed-off-by: Filip Bozuta <Filip.Bozuta@syrmia.com> Reviewed-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <20200824223050.92032-2-Filip.Bozuta@syrmia.com> [lv: rebase and fix do_pselect6()] Signed-off-by: Laurent Vivier <laurent@vivier.eu>

2020-09-04ui/gtk: Update refresh interval after widget is realizedPhilippe Mathieu-Daudé
Nikola reported on Windows when gd_vc_gfx_init() is called, the window is not yet realized, so we run gd_refresh_rate_millihz(NULL) which returns 0 milli-Hertz. When a Widget is realized, it fires a 'realized' event. We already have the gd_draw_event() handler registered for this even, so simply move the gd_refresh_rate_millihz() there. When the event fires, the window is known to exist. This completes commit c4c00922cc original intention.

2020-09-04ui: Add more mouse buttons to SPICEFrediano Ziglio
Add support for SIDE and EXTRA buttons. The constants for buttons in both SPICE and QEMU are defined as LEFT MIDDLE RIGHT UP DOWN SIDE EXTRA (same order). "button_mask" contains for each bit the state of a button. Qemu currently uses bits 0, 1, 2 respectively as LEFT, RIGHT, MIDDLE; also add bits 4 and 5 as UP and DOWN (using wheel movements). SPICE protocol uses a bitmask based on the order above where LEFT is bit 0, MIDDLE is bit 1 and so on till EXTRA being bit 6. To avoid clash with Qemu usage SPICE bitmask from SIDE are move a bit more resulting respectively in 0x40 and 0x80 values.

2020-09-03tcg: Fix tcg gen for vectorized absolute valueStephen Long
The fallback inline expansion for vectorized absolute value, when the host doesn't support such an insn was flawed. E.g. when a vector of bytes has all elements negative, mask will be 0xffff_ffff_ffff_ffff. Subtracting mask only adds 1 to the low element instead of all elements becase -mask is 1 and not 0x0101_0101_0101_0101.

2020-09-03cputlb: Make store_helper less fragile to compiler optimizationsRichard Henderson
This has no functional change. The current function structure is: inline QEMU_ALWAYSINLINE store_memop() { switch () { ... default: qemu_build_not_reached(); } } inline QEMU_ALWAYSINLINE store_helper() { ... if (span_two_pages_or_io) { ... helper_ret_stb_mmu(); } store_memop(); } helper_ret_stb_mmu() { store_helper(); } Whereas GCC will generate an error at compile-time when an always_inline function is not inlined, Clang does not. Nor does Clang prioritize the inlining of always_inline functions. Both of these are arguably bugs. Both `store_memop` and `store_helper` need to be inlined and allow constant propogations to eliminate the `qemu_build_not_reached` call. However, if the compiler instead chooses to inline helper_ret_stb_mmu into store_helper, then store_helper is now self-recursive and the compiler is no longer able to propagate the constant in the same way. This does not produce at current QEMU head, but was reproducible at v4.2.0 with `clang-10 -O2 -fexperimental-new-pass-manager`. The inline recursion problem can be fixed solely by marking helper_ret_stb_mmu as noinline, so the compiler does not make an incorrect decision about which functions to inline. In addition, extract store_helper_unaligned as a noinline subroutine that can be shared by all of the helpers. This saves about 6k code size in an optimized x86_64 build.

The default expiration time for artifacts seems to be very high (30 days?).

2020-09-03meson: fix keymaps without qemu-keymapGerd Hoffmann
In case the qemu-keymap tool generating them is neither installed on the system nor built from sources (due to xkbcommon not being available) qemu will not find the keymaps when started directly from the build tree, This happens because commit ddcf607fa3d6 ("meson: drop keymaps symlink") removed the symlink to the source tree, and the special handling for install doesn't help in case we do not install qemu. Lets fix that by simply copying over the file from the source tree as fallback.

2020-09-03cirrus.yml: Split FreeBSD job into two partsThomas Huth
The FreeBSD jobs currently hit the 1h time limit in the Cirrus-CI. We have to split the build targets here to make sure that the job finishes in time again. According to the Cirrus-CI docs and some tests that I did, it also seems like the total amount of CPUs that can be used for FreeBSD jobs is limited to 8, so each job now only gets 4 CPUs. That increases the compilation time of each job a little bit, but it still seems to be better to run two jobs with 4 CPUs each in parallel than to run two jobs with 8 CPUs sequentially.

When using --enable-werror for the macOS builders in the Cirrus-CI, the atomic64 test is currently failing, and config.log shows a bunch of error messages like this: config-temp/qemu-conf.c:6:7: error: implicit declaration of function '__atomic_load_8' is invalid in C99 [-Werror,-Wimplicit-function-declaration] y = __atomic_load_8(&x, 0); ^ config-temp/qemu-conf.c:6:7: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes] Seems like these __atomic_*_8 functions are available in one of the libraries there, so that the test links and passes there when not using --enable-werror. But there does not seem to be a valid prototype for them in any of the header files, so that the test fails when using --enable-werror. Fix it by using the "official" built-in functions instead (see e.g. https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html). We are not using the *_8 variants in QEMU anyway.

This was different in the very first versions of the patches to add blockdev-add and we probably just forgot to update the documentation after removing it. So remove the stale bits. And the requirement for 'node-name' is already mentioned in the documentation of @BlockdevOptions: [...] # @node-name: the node name of the new node (Since 2.0). # This option is required on the top level of blockdev-add. # Valid node names start with an alphabetic character and may # contain only alphanumeric characters, '-', '.' and '_'.

2020-09-03qapi: enable use of g_autoptr with QAPI typesDaniel P. Berrangé
Currently QAPI generates a type and function for free'ing it: typedef struct QCryptoBlockCreateOptions QCryptoBlockCreateOptions; void qapi_free_QCryptoBlockCreateOptions(QCryptoBlockCreateOptions *obj); This is used in the traditional manner: QCryptoBlockCreateOptions *opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... qapi_free_QCryptoBlockCreateOptions(opts); Since bumping the min glib to 2.48, QEMU has incrementally adopted the use of g_auto/g_autoptr. This allows the compiler to run a function to free a variable when it goes out of scope, the benefit being the compiler can guarantee it is freed in all possible code ptahs. This benefit is applicable to QAPI types too, and given the seriously long method names for some qapi_free_XXXX() functions, is much less typing. This change thus makes the code generator emit: G_DEFINE_AUTOPTR_CLEANUP_FUNC(QCryptoBlockCreateOptions, qapi_free_QCryptoBlockCreateOptions) The above code example now becomes g_autoptr(QCryptoBlockCreateOptions) opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... Note, if the local pointer needs to live beyond the scope holding the variable, then g_steal_pointer can be used. This is useful to return the pointer to the caller in the success codepath, while letting it be freed in all error codepaths. return g_steal_pointer(&opts); The crypto/block.h header needs updating to avoid symbol clash now that the g_autoptr support is a standard QAPI feature.

2020-09-03linux-user: Add support for btrfs ioctls used to scrub a filesystemFilip Bozuta
This patch implements functionality for following ioctls: BTRFS_IOC_SCRUB - Starting a btrfs filesystem scrub Start a btrfs filesystem scrub. The third ioctls argument is a pointer to a following type: struct btrfs_ioctl_scrub_args { __u64 devid; /* in */ __u64 start; /* in */ __u64 end; /* in */ __u64 flags; /* in */ struct btrfs_scrub_progress progress; /* out */ /* pad to 1k */ __u64 unused[(1024-32-sizeof(struct btrfs_scrub_progress))/8]; }; Before calling this ioctl, field 'devid' should be filled with value that represents the device id of the btrfs filesystem for which the scrub is to be started. BTRFS_IOC_SCRUB_CANCEL - Canceling scrub of a btrfs filesystem Cancel a btrfs filesystem scrub if it is running. The third ioctls argument is ignored. BTRFS_IOC_SCRUB_PROGRESS - Getting status of a running scrub Read the status of a running btrfs filesystem scrub. The third ioctls argument is a pointer to the above mentioned 'struct btrfs_ioctl_scrub_args'. Similarly as with 'BTRFS_IOC_SCRUB', the 'devid' field should be filled with value that represents the id of the btrfs device for which the scrub has started. The status of a running scrub is returned in the field 'progress' which is of type 'struct btrfs_scrub_progress' and its definition can be found at: https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/btrfs.h#L150 Implementation nots: Ioctls in this patch use type 'struct btrfs_ioctl_scrub_args' as their third argument.

2020-09-03linux-user: Add support for btrfs ioctls used to manage quotaFilip Bozuta
This patch implements functionality for following ioctls: BTRFS_IOC_QUOTA_CTL - Enabling/Disabling quota support Enable or disable quota support for a btrfs filesystem. Quota support is enabled or disabled using the ioctls third argument which represents a pointer to a following type: struct btrfs_ioctl_quota_ctl_args { __u64 cmd; __u64 status; }; Before calling this ioctl, the 'cmd' field should be filled with one of the values 'BTRFS_QUOTA_CTL_ENABLE' (enabling quota) 'BTRFS_QUOTA_CTL_DISABLE' (disabling quota). BTRFS_IOC_QGROUP_CREATE - Creating/Removing a subvolume quota group Create or remove a subvolume quota group. The subvolume quota group is created or removed using the ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_qgroup_create_args { __u64 create; __u64 qgroupid; }; Before calling this ioctl, the 'create' field should be filled with the aproppriate value depending on if the user wants to create or remove a quota group (0 for removing, everything else for creating). Also, the 'qgroupid' field should be filled with the value for the quota group id that is to be created. BTRFS_IOC_QGROUP_ASSIGN - Asigning or removing a quota group as child group Asign or remove a quota group as child quota group of another group in the btrfs filesystem. The asignment is done using the ioctl's third argument which represents a pointert to a following type: struct btrfs_ioctl_qgroup_assign_args { __u64 assign; __u64 src; __u64 dst; }; Before calling this ioctl, the 'assign' field should be filled with the aproppriate value depending on if the user wants to asign or remove a quota group as a child quota group of another group (0 for removing, everythin else for asigning). Also, the 'src' and 'dst' fields should be filled with the aproppriate quota group id values depending on which quota group needs to asigned or removed as child quota group of another group ('src' gets asigned or removed as child group of 'dst'). BTRFS_IOC_QGROUP_LIMIT - Limiting the size of a quota group Limit the size of a quota group. The size of the quota group is limited with the ioctls third argument which represents a pointer to a following type: struct btrfs_ioctl_qgroup_limit_args { __u64 qgroupid; struct btrfs_qgroup_limit lim; }; Before calling this ioctl, the 'qgroup' id field should be filled with aproppriate value of the quota group id for which the size is to be limited. The second field is of following type: struct btrfs_qgroup_limit { __u64 flags; __u64 max_rfer; __u64 max_excl; __u64 rsv_rfer; __u64 rsv_excl; }; The 'max_rfer' field should be filled with the size to which the quota group should be limited. The 'flags' field can be used for passing additional options and can have values which can be found on: https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/btrfs.h#L67 BTRFS_IOC_QUOTA_RESCAN_STATUS - Checking status of running rescan operation Check status of a running rescan operation. The status is checked using the ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_quota_rescan_args { __u64 flags; __u64 progress; __u64 reserved[6]; }; If there is a rescan operation running, 'flags' field is set to 1, and 'progress' field is set to aproppriate value which represents the progress of the operation. BTRFS_IOC_QUOTA_RESCAN - Starting a rescan operation Start ar rescan operation to Trash all quota groups and scan the metadata again with the current config. Before calling this ioctl, BTRFS_IOC_QUOTA_RESCAN_STATUS sould be run to check if there is already a rescan operation runing. After that ioctl call, the received 'struct btrfs_ioctl_quota_rescan_args' should be than passed as this ioctls third argument. BTRFS_IOC_QUOTA_RESCAN_WAIT - Waiting for a rescan operation to finish Wait until a rescan operation is finished (if there is a rescan operation running). The third ioctls argument is ignored. Implementation notes: Almost all of the ioctls in this patch use structure types as third arguments. That is the reason why aproppriate thunk definitions were added in file 'syscall_types.h'.
