Filip Bozuta	9a5a5a0552	linux-user: Add support for btrfs ioctls used to scrub a filesystem 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.

Filip Bozuta	53906f689d	linux-user: Add support for btrfs ioctls used to manage quota 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'.

Filip Bozuta	784c08c8c4	linux-user: Add support for two btrfs ioctls used for subvolume This patch implements functionality for following ioctl: BTRFS_IOC_DEFAULT_SUBVOL - Setting a default subvolume Set a default subvolume for a btrfs filesystem. The third ioctl's argument is a '__u64' (unsigned long long) which represents the id of a subvolume that is to be set as the default. BTRFS_IOC_GET_SUBVOL_ROOTREF - Getting tree and directory id of subvolumes Read tree and directory id of subvolumes from a btrfs filesystem. The tree and directory id's are returned in the ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_get_subvol_rootref_args { /* in/out, minimum id of rootref's treeid to be searched / __u64 min_treeid; / out / struct { __u64 treeid; __u64 dirid; } rootref[BTRFS_MAX_ROOTREF_BUFFER_NUM]; / out, number of found items */ __u8 num_items; __u8 align[7]; }; Before calling this ioctl, 'min_treeid' field should be filled with value that represent the minimum value for the tree id. Implementation notes: Ioctl BTRFS_IOC_GET_SUBVOL_ROOTREF uses the above mentioned structure type as third argument. That is the reason why a aproppriate thunk structure definition is added in file 'syscall_types.h'. Signed-off-by: Filip Bozuta <Filip.Bozuta@syrmia.com> Tested-by: Daniel P.

Filip Bozuta	0ff496a05f	linux-user: Add support for a group of btrfs inode ioctls This patch implements functionality of following ioctls: BTRFS_IOC_INO_LOOKUP - Reading tree root id and path Read tree root id and path for a given file or directory. The name and tree root id are returned in an ioctl's third argument that represents a pointer to a following type: struct btrfs_ioctl_ino_lookup_args { __u64 treeid; __u64 objectid; char name[BTRFS_INO_LOOKUP_PATH_MAX]; }; Before calling this ioctl, field 'objectid' should be filled with the object id value for which the tree id and path are to be read. Value 'BTRFS_FIRST_FREE_OBJECTID' represents the object id for the first available btrfs object (directory or file). BTRFS_IOC_INO_PATHS - Reading paths to all files Read path to all files with a certain inode number. The paths are returned in the ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_ino_path_args { __u64 inum; /* in / __u64 size; / in / __u64 reserved[4]; / struct btrfs_data_container fspath; out / __u64 fspath; /* out / }; Before calling this ioctl, the 'inum' and 'size' field should be filled with the aproppriate inode number and size of the directory where file paths should be looked for. For now, the paths are returned in an '__u64' (unsigned long long) value 'fspath'. BTRFS_IOC_LOGICAL_INO - Reading inode numbers Read inode numbers for files on a certain logical adress. The inode numbers are returned in the ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_logical_ino_args { __u64 logical; / in / __u64 size; / in / __u64 reserved[3]; / must be 0 for now / __u64 flags; / in, v2 only / / struct btrfs_data_container inodes; out / __u64 inodes; }; Before calling this ioctl, the 'logical' and 'size' field should be filled with the aproppriate logical adress and size of where the inode numbers of files should be looked for. For now, the inode numbers are returned in an '__u64' (unsigned long long) value 'inodes'. BTRFS_IOC_LOGICAL_INO_V2 - Reading inode numbers Same as the above mentioned ioctl except that it allows passing a flags 'BTRFS_LOGICAL_INO_ARGS_IGNORE_OFFSET'. BTRFS_IOC_INO_LOOKUP_USER - Reading subvolume name and path Read name and path of a subvolume. The tree root id and path are read in an ioctl's third argument which represents a pointer to a following type: struct btrfs_ioctl_ino_lookup_user_args { /* in, inode number containing the subvolume of 'subvolid' / __u64 dirid; / in / __u64 treeid; / out, name of the subvolume of 'treeid' / char name[BTRFS_VOL_NAME_MAX + 1]; / * out, constructed path from the directory with which the ioctl is * called to dirid */ char path[BTRFS_INO_LOOKUP_USER_PATH_MAX]; }; Before calling this ioctl, the 'dirid' and 'treeid' field should be filled with aproppriate values which represent the inode number of the directory that contains the subvolume and treeid of the subvolume. Implementation notes: 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'.

Filip Bozuta	49b422a8c5	linux-user: Add support for btrfs ioctls used to get/set features This patch implements functionality for following ioctls: BTRFS_IOC_GET_FEATURES - Getting feature flags Read feature flags for a btrfs filesystem. The feature flags are returned inside the ioctl's third argument which represents a pointer to a following structure type: struct btrfs_ioctl_feature_flags { __u64 compat_flags; __u64 compat_ro_flags; __u64 incompat_flags; }; All of the structure field represent bit masks that can be composed of values which can be found on: https://elixir.bootlin.com/linux/latest/source/fs/btrfs/ctree.h#L282 BTRFS_IOC_SET_FEATURES - Setting feature flags Set and clear feature flags for a btrfs filesystem. The feature flags are set using the ioctl's third argument which represents a 'struct btrfs_ioctl_feature_flags[2]' array. The first element of the array represent flags which are to be cleared and the second element of the array represent flags which are to be set. The second element has the priority over the first, which means that if there are matching flags in the elements, they will be set in the filesystem. If the flag values in the third argument aren't correctly set to be composed of the available predefined flag values, errno ENOPERM ("Operation not permitted") is returned. BTRFS_IOC_GET_SUPPORTED_FEATURES - Getting supported feature flags Read supported feature flags for a btrfs filesystem. The supported feature flags are read using the ioctl's third argument which represents a 'struct btrfs_ioctl_feature_flags[3]' array. The first element of this array represents all of the supported flags in the btrfs filesystem. The second element represents flags that can be safely set and third element represent flags that can be safely clearead. Implementation notes: All of the implemented ioctls use 'struct btrfs_ioctl_feature_flags' as third argument. That is the reason why a corresponding defintion was added in file 'linux-user/syscall_types.h'. Signed-off-by: Filip Bozuta <Filip.Bozuta@syrmia.com> Tested-by: Daniel P.

Filip Bozuta	9bbd60e7f7	linux-user: Add support for btrfs ioctls used to manipulate with devices This patch implements functionality for following ioctls: BTRFS_IOC_SCAN_DEV - Scanning device for a btrfs filesystem Scan a device for a btrfs filesystem. The device that is to be scanned is passed in the ioctl's third argument which represents a pointer to a 'struct ioc_vol_args' (which was mentioned in a previous patch). Before calling this ioctl, the name field of this structure should be filled with the aproppriate name value which represents a path for the device. If the device contains a btrfs filesystem, the ioctl returns 0, otherwise a negative value is returned. BTRFS_IOC_ADD_DEV - Adding a device to a btrfs filesystem Add a device to a btrfs filesystem. The device that is to be added is passed in the ioctl's third argument which represents a pointer to a 'struct ioc_vol_args' (which was mentioned in a previous patch). Before calling this ioctl, the name field of this structure should be filled with the aproppriate name value which represents a path for the device. BTRFS_IOC_RM_DEV - Removing a device from a btrfs filesystem Remove a device from a btrfs filesystem. The device that is to be removed is passed in the ioctl's third argument which represents a pointer to a 'struct ioc_vol_args' (which was mentioned in a previous patch). Before calling this ioctl, the name field of this structure should be filled with the aproppriate name value which represents a path for the device. BTRFS_IOC_DEV_INFO - Getting information about a device Obtain information for device in a btrfs filesystem. The information is gathered in the ioctl's third argument which represents a pointer to a following structure type: struct btrfs_ioctl_dev_info_args { __u64 devid; /* in/out / __u8 uuid[BTRFS_UUID_SIZE]; / in/out / __u64 bytes_used; / out / __u64 total_bytes; / out / __u64 unused[379]; / pad to 4k / __u8 path[BTRFS_DEVICE_PATH_NAME_MAX]; / out / }; Before calling this ioctl, field "devid" should be set with the id value for the device for which the information is to be obtained. If this field is not aproppriately set, the errno ENODEV ("No such device") is returned. BTRFS_IOC_GET_DEV_STATS - Getting device statistics Obtain stats informatin for device in a btrfs filesystem. The information is gathered in the ioctl's third argument which represents a pointer to a following structure type: struct btrfs_ioctl_get_dev_stats { __u64 devid; / in / __u64 nr_items; / in/out / __u64 flags; / in/out / / out values: / __u64 values[BTRFS_DEV_STAT_VALUES_MAX]; / * This pads the struct to 1032 bytes. It was originally meant to pad to * 1024 bytes, but when adding the flags field, the padding calculation * was not adjusted. */ __u64 unused[128 - 2 - BTRFS_DEV_STAT_VALUES_MAX]; }; Before calling this ioctl, field "devid" should be set with the id value for the device for which the information is to be obtained. If this field is not aproppriately set, the errno ENODEV ("No such device") is returned. BTRFS_IOC_FORGET_DEV - Remove unmounted devices Search and remove all stale devices (devices which are not mounted). The third ioctl argument is a pointer to a 'struct btrfs_ioctl_vol_args'. The ioctl call will release all unmounted devices which match the path which is specified in the "name" field of the structure. If an empty path ("") is specified, all unmounted devices will be released. Implementation notes: Ioctls BTRFS_IOC_DEV_INFO and BTRFS_IOC_GET_DEV_STATS use types 'struct btrfs_ioctl_dev_info_args' and ' struct btrfs_ioctl_get_dev_stats' as third argument types. That is the reason why corresponding structure definitions were added in file 'linux-user/syscall_types.h'. Since the thunk type for 'struct ioc_vol_args' was already added in a previous patch, the rest of the implementation was straightforward.

Filip Bozuta	527e8d8fe0	linux-user: Add support for a group of btrfs ioctls used for snapshots This patch implements functionality for following ioctls: BTRFS_IOC_SNAP_CREATE - Creating a subvolume snapshot Create a snapshot of a btrfs subvolume. The snapshot is created using the ioctl's third argument that is a pointer to a 'struct btrfs_ioctl_vol_args' (which was mentioned in the previous patch). Before calling this ioctl, the fields of the structure should be filled with aproppriate values for the file descriptor and path of the subvolume for which the snapshot is to be created. BTRFS_IOC_SNAP_DESTROY - Removing a subvolume snapshot Delete a snapshot of a btrfs subvolume. The snapshot is deleted using the ioctl's third argument that is a pointer to a 'struct btrfs_ioctl_vol_args' (which was mentioned in the previous patch). Before calling this ioctl, the fields of the structure should be filled with aproppriate values for the file descriptor and path of the subvolume for which the snapshot is to be deleted. Implementation notes: Since the thunk type 'struct btrfs_ioctl_vol_args' is defined in the previous patch, the implementation for these ioctls was straightforward.

Filip Bozuta	d6092e085d	linux-user: Add support for a group of btrfs ioctls used for subvolumes This patch implements functionality of following ioctls: BTRFS_IOC_SUBVOL_CREATE - Creating a btrfs subvolume Create a btrfs subvolume. The subvolume is created using the ioctl's third argument which represents a pointer to a following structure type: struct btrfs_ioctl_vol_args { __s64 fd; char name[BTRFS_PATH_NAME_MAX + 1]; }; Before calling this ioctl, the fields of this structure should be filled with aproppriate values. The fd field represents the file descriptor value of the subvolume and the name field represents the subvolume path. BTRFS_IOC_SUBVOL_GETFLAGS - Getting subvolume flags Read the flags of the btrfs subvolume. The flags are read using the ioctl's third argument that is a pointer of __u64 (unsigned long). The third argument represents a bit mask that can be composed of following values: BTRFS_SUBVOL_RDONLY (1ULL << 1) BTRFS_SUBVOL_QGROUP_INHERIT (1ULL << 2) BTRFS_DEVICE_SPEC_BY_ID (1ULL << 3) BTRFS_SUBVOL_SPEC_BY_ID (1ULL << 4) BTRFS_IOC_SUBVOL_SETFLAGS - Setting subvolume flags Set the flags of the btrfs subvolume. The flags are set using the ioctl's third argument that is a pointer of __u64 (unsigned long). The third argument represents a bit mask that can be composed of same values as in the case of previous ioctl (BTRFS_IOC_SUBVOL_GETFLAGS). BTRFS_IOC_SUBVOL_GETINFO - Getting subvolume information Read information about the subvolume. The subvolume information is returned in the ioctl's third argument which represents a pointer to a following structure type: struct btrfs_ioctl_get_subvol_info_args { /* Id of this subvolume / __u64 treeid; / Name of this subvolume, used to get the real name at mount point / char name[BTRFS_VOL_NAME_MAX + 1]; / * Id of the subvolume which contains this subvolume. * Zero for top-level subvolume or a deleted subvolume. / __u64 parent_id; / * Inode number of the directory which contains this subvolume. * Zero for top-level subvolume or a deleted subvolume / __u64 dirid; / Latest transaction id of this subvolume / __u64 generation; / Flags of this subvolume / __u64 flags; / UUID of this subvolume / __u8 uuid[BTRFS_UUID_SIZE]; / * UUID of the subvolume of which this subvolume is a snapshot. * All zero for a non-snapshot subvolume. / __u8 parent_uuid[BTRFS_UUID_SIZE]; / * UUID of the subvolume from which this subvolume was received. * All zero for non-received subvolume. / __u8 received_uuid[BTRFS_UUID_SIZE]; / Transaction id indicating when change/create/send/receive happened / __u64 ctransid; __u64 otransid; __u64 stransid; __u64 rtransid; / Time corresponding to c/o/s/rtransid / struct btrfs_ioctl_timespec ctime; struct btrfs_ioctl_timespec otime; struct btrfs_ioctl_timespec stime; struct btrfs_ioctl_timespec rtime; / Must be zero */ __u64 reserved[8]; }; All of the fields of this structure are filled after the ioctl call. Implementation notes: Ioctls BTRFS_IOC_SUBVOL_CREATE and BTRFS_IOC_SUBVOL_GETINFO have structure types as third arguments. That is the reason why a corresponding definition are added in file 'linux-user/syscall_types.h'. The line '#include <linux/btrfs.h>' is added in file 'linux-user/syscall.c' to recognise preprocessor definitions for these ioctls. Since the file "linux/btrfs.h" was added in the kernel version 3.9, it is enwrapped in an #ifdef statement with parameter CONFIG_BTRFS which is defined in 'configure' if the header file is present.

Filip Bozuta	a20a7c2640	linux-user: Add thunk argument types for SIOCGSTAMP and SIOCGSTAMPNS Socket ioctls SIOCGSTAMP and SIOCGSTAMPNS, used for timestamping the socket connection, are defined in file "ioctls.h" differently from other ioctls. The reason for this difference is explained in the comments above their definition. These ioctls didn't have defined thunk argument types before changes from this patch. They have special handling functions ("do_ioctl_SIOCGSTAMP" and "do_ioctl_SIOCGSTAMPNS") that take care of setting values for approppriate argument types (struct timeval and struct timespec) and thus no thunk argument types were needed for their implementation. But this patch adds those argument type definitions in file "syscall_types.h" and "ioctls.h" as it is needed for printing arguments of these ioctls with strace. Implementation notes: There are two variants of these ioctls: SIOCGSTAMP_OLD/SIOCGSTAM_NEW and SIOCGSTAMPNS_OLD/SIOCGSTAMPNS_NEW. One is the old existing definition and the other is the 2038 safe variant used for 32-bit architectures. Corresponding structure definitions STRUCT_timespec/STRUCT__kernel_timespec and STRUCT_timeval/STRUCT__kernel_sock_timeval were added for these variants. STRUCT_timeval definition was already inside the file as it is used by another implemented ioctl. Two cases were added for definitions STRUCT_timeval/STRUCT__kernel_sock_timeval to manage the case when the "u_sec" field of the timeval structure is of type int.

Filip Bozuta	fe333025c6	linux-user: Add support for getting/setting selected alsa timer parameters using ioctls This patch implements functionalities of following ioctls: SNDRV_TIMER_IOCTL_INFO - Getting information about selected timer Read information about the selected timer. The information is returned in the following structure: struct snd_timer_info { unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* / int card; / card number / unsigned char id[64]; / timer identificator / unsigned char name[80]; / timer name / unsigned long reserved0; / reserved for future use / unsigned long resolution; / average period resolution in ns / unsigned char reserved[64]; / reserved for future use / }; A pointer to this structure should be passed as the third ioctl's argument. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer which information is to be obtained. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. SNDRV_TIMER_IOCTL_PARAMS - Setting parameters for selected timer Sets parameters for the selected timer.

Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer which parameters are to be set. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. SNDRV_TIMER_IOCTL_STATUS - Getting status of selected timer Read status of the selected timer. The status of the timer is returned in the following structure: struct snd_timer_status { struct timespec tstamp; / Timestamp - last update / unsigned int resolution; / current period resolution in ns / unsigned int lost; / counter of master tick lost / unsigned int overrun; / count of read queue overruns / unsigned int queue; / used queue size / unsigned char reserved[64]; / reserved */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer which status is to be obtained.

Implementation notes: All ioctls in this patch have pointer to some kind of a structure as their third argument. That is the reason why corresponding definitions were added in 'linux-user/syscall_types.h'. Structure 'snd_timer_status' has field of type 'struct timespec' which is why a corresponding definition of that structure was also added in 'linux-user/syscall_types.h'. All of these strucutures have some fields that are of type 'unsigned long'. That is the reason why separate target structures were defined in 'linux-user/syscall_defs.h'. Structure 'struct timespec' already had a separate target definition so that definition was used to define a target structure for 'snd_timer_status'. The rest of the implementation was straightforward.

Filip Bozuta	1c4c6fcd1a	linux-user: Add support for getting alsa timer version and id This patch implements functionalities of following ioctls: SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version Read the sound timer version. The third ioctl's argument is a pointer to an int in which the specified timers version is returned. SNDRV_TIMER_IOCTL_NEXT_DEVICE - Getting id information about next timer Read id information about the next timer device from the sound timer device list. The id infomration is returned in the following structure: struct snd_timer_id { int dev_class; /* timer device class number / int dev_sclass; / slave device class number (unused) / int card; / card number / int device; / device number / int subdevice; / sub-device number */ }; The devices in the sound timer device list are arranged by the fields of this structure respectively (first by dev_class number, then by card number, ...). A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the parameters of this structure should be initialized in relation to the next timer device which information is to be obtained. For example, if a wanted timer device has the device class number equal to or bigger then 2, the field dev_class should be initialized to 2. After the ioctl call, the structure fields are filled with values from the next device in the sound timer device list. If there is no next device in the list, the structure is filled with "zero" id values (in that case all fields are filled with value -1). Implementation notes: The ioctl 'SNDRV_TIMER_IOCTL_NEXT_DEVICE' has a pointer to a 'struct snd_timer_id' as its third argument. That is the reason why corresponding definition is added in 'linux-user/syscall_types.h'. Since all elements of this structure are of type 'int', the rest of the implementation was straightforward. The line '#include <linux/rtc.h>' was added to recognize preprocessor definitions for these ioctls. This needs to be done only once in this series of commits. Also, the content of this file (with respect to ioctl definitions) remained unchanged for a long time, therefore there is no need to worry about supporting older Linux kernel version.

The pending flag is used by RTC_WKALM_RD to report a pending interrupt (so it's mostly useless on Linux, except when talking to the RTC managed by EFI firmware). The time field is as used with RTC_ALM_READ and RTC_ALM_SET except that the tm_mday, tm_mon, and tm_year fields are also valid. A pointer to this structure should be passed as the third ioctl's argument. Implementation notes: All ioctls in this patch have a pointer to a structure rtc_wkalrm as their third argument.

Daniel P. Berrangé	6d5d5dde9a	linux-user: fix to handle variably sized SIOCGSTAMP with new kernels The SIOCGSTAMP symbol was previously defined in the asm-generic/sockios.h header file. QEMU sees that header indirectly via sys/socket.h In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115 the asm-generic/sockios.h header no longer defines SIOCGSTAMP. Instead it provides only SIOCGSTAMP_OLD, which only uses a 32-bit time_t on 32-bit architectures. The linux/sockios.h header then defines SIOCGSTAMP using either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even on 32-bit architectures To cope with this we must now convert the old and new type from the target to the host one.
