linux-user: Fix 'semop()' and 'semtimedop()' implementation The implementations of syscalls 'semop()' and 'semtimedop()' in file 'syscall.c' use function 'target_to_host_sembuf()' to convert values of 'struct sembuf' from host to target. However, before this conversion it should be check whether the number of semaphore operations 'nsops' is not bigger than maximum allowed semaphor operations per syscall: 'SEMOPM'. In these cases, errno 'E2BIG' ("Arg list too long") should be set. But the implementation will set errno 'EFAULT' ("Bad address") in this case since the conversion from target to host in this case fails. This was confirmed with the LTP test for 'semop()' ('ipc/semop/semop02') in test case where 'nsops' is greater than SEMOPM with unaproppriate errno EFAULT: semop02.c:130: FAIL: semop failed unexpectedly; expected: E2BIG: EFAULT (14) This patch changes this by adding a check whether 'nsops' is bigger than 'SEMOPM' before the conversion function 'target_to_host_sembuf()' is called. After the changes from this patch, the test works fine along with the other LTP testcases for 'semop()'): semop02.c:126: PASS: semop failed as expected: E2BIG (7) Implementation notes: A target value ('TARGET_SEMOPM') was added for 'SEMOPM' as to be sure in case the value is not available for some targets.

linux-user: Add support for a group of 2038 safe syscalls This patch implements functionality for following time64 syscalls: *clock_getres_time64 This a year 2038 safe variant of syscall: int clock_getres(clockid_t clockid, struct timespec *res) --finding the resoultion of a specified clock-- man page: https://man7.org/linux/man-pages/man2/clock_getres.2.html *timer_gettime64 *timer_settime64 These are year 2038 safe variants of syscalls: int timer_settime(timer_t timerid, int flags, const struct itimerspec *new_value, struct itimerspec *old_value) int timer_gettime(timer_t timerid, struct itimerspec *curr_value) --arming/dissarming and fetching state of POSIX per-process timer-- man page: https://man7.org/linux/man-pages/man2/timer_settime.2.html *timerfd_gettime64 *timerfd_settime64 These are year 2038 safe variants of syscalls: int timerfd_settime(int fd, int flags, const struct itimerspec *new_value, struct itimerspec *old_value) int timerfd_gettime(int fd, struct itimerspec *curr_value) --timers that notify via file descriptor-- man page: https://man7.org/linux/man-pages/man2/timerfd_settime.2.html Implementation notes: Syscall 'clock_getres_time64' was implemented similarly to 'clock_getres()'. The only difference was that for the conversion of 'struct timespec' from host to target, function 'host_to_target_timespec64()' was used instead of 'host_to_target_timespec()'. For other syscalls, new functions 'host_to_target_itimerspec64()' and 'target_to_host_itimerspec64()' were added to convert the value of the 'struct itimerspec' from host to target and vice versa. A new type 'struct target__kernel_itimerspec' was added in 'syscall_defs.h'. This type was defined with fields which are of the already defined type 'struct target_timespec'. This new 'struct target__kernel_itimerspec' type is used in these new converting functions. These new functions were defined similarly to 'host_to_target_itimerspec()' and 'target_to_host_itimerspec()' the only difference being that 'target_to_host_timespec64()' and 'host_to_target_timespec64()' were used.

For 'clock_adjtime64()' a 64-bit target kernel version of 'struct timex' was defined in 'syscall_defs.h': 'struct target__kernel_timex'. This type was used to convert the values of 64-bit timex type between host and target. For this purpose a 64-bit timex converting functions 'target_to_host_timex64()' and 'host_to_target_timex64()'. An existing function 'copy_to_user_timeval64()' was used to convert the field 'time' which if of type 'struct timeval' from host to target. Function 'copy_from_user_timveal64()' was added in this patch and used to convert the 'time' field from target to host.

linux-user: Add support for getting/setting RTC PLL correction using ioctls This patch implements functionalities of following ioctls: RTC_PLL_GET - Getting PLL correction Read the PLL correction for RTCs that support PLL. The PLL correction is returned in the following structure: struct rtc_pll_info { int pll_ctrl; /* placeholder for fancier control */ int pll_value; /* get/set correction value */ int pll_max; /* max +ve (faster) adjustment value */ int pll_min; /* max -ve (slower) adjustment value */ int pll_posmult; /* factor for +ve correction */ int pll_negmult; /* factor for -ve correction */ long pll_clock; /* base PLL frequency */ }; A pointer to this structure should be passed as the third ioctl's argument. RTC_PLL_SET - Setting PLL correction Sets the PLL correction for RTCs that support PLL. The PLL correction that is set is specified by the rtc_pll_info structure pointed to by the third ioctl's' argument. Implementation notes: All ioctls in this patch have a pointer to a structure rtc_pll_info as their third argument. All elements of this structure are of type 'int', except the last one that is of type 'long'. That is the reason why a separate target structure (target_rtc_pll_info) is defined in linux-user/syscall_defs. The rest of the implementation is straightforward.

linux-user: Add support for enabling/disabling RTC features using ioctls This patch implements functionalities of following ioctls: RTC_AIE_ON, RTC_AIE_OFF - Alarm interrupt enabling on/off Enable or disable the alarm interrupt, for RTCs that support alarms. The third ioctl's argument is ignored. RTC_UIE_ON, RTC_UIE_OFF - Update interrupt enabling on/off Enable or disable the interrupt on every clock update, for RTCs that support this once-per-second interrupt. The third ioctl's argument is ignored. RTC_PIE_ON, RTC_PIE_OFF - Periodic interrupt enabling on/off Enable or disable the periodic interrupt, for RTCs that sup‐ port these periodic interrupts. The third ioctl's argument is ignored. Only a privileged process (i.e., one having the CAP_SYS_RESOURCE capability) can enable the periodic interrupt if the frequency is currently set above the value specified in /proc/sys/dev/rtc/max-user-freq. RTC_WIE_ON, RTC_WIE_OFF - Watchdog interrupt enabling on/off Enable or disable the Watchdog interrupt, for RTCs that sup- port this Watchdog interrupt. The third ioctl's argument is ignored. Implementation notes: Since all of involved ioctls have NULL as their third argument, their 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.

A pointer to this structure should be passed as the third ioctl's argument. RTC_SET_TIME - Setting RTC time Sets this RTC's time to the time specified by the rtc_time structure pointed to by the third ioctl's argument. To set the RTC's time the process must be privileged (i.e., have the CAP_SYS_TIME capability). RTC_ALM_READ, RTC_ALM_SET - Getting/Setting alarm time Read and set the alarm time, for RTCs that support alarms. The alarm interrupt must be separately enabled or disabled using the RTC_AIE_ON, RTC_AIE_OFF requests. The third ioctl's argument is a pointer to a rtc_time structure. Only the tm_sec, tm_min, and tm_hour fields of this structure are used. Implementation notes: All ioctls in this patch have pointer to a structure rtc_time as their third argument.

linux-user: Add support for getting/setting RTC periodic interrupt and epoch using ioctls This patch implements functionalities of following ioctls: RTC_IRQP_READ, RTC_IRQP_SET - Getting/Setting IRQ rate Read and set the frequency for periodic interrupts, for RTCs that support periodic interrupts. The periodic interrupt must be separately enabled or disabled using the RTC_PIE_ON, RTC_PIE_OFF requests. The third ioctl's argument is an unsigned long * or an unsigned long, respectively. The value is the frequency in interrupts per second. The set of allow‐ able frequencies is the multiples of two in the range 2 to 8192. Only a privileged process (i.e., one having the CAP_SYS_RESOURCE capability) can set frequencies above the value specified in /proc/sys/dev/rtc/max-user-freq. (This file contains the value 64 by default.) RTC_EPOCH_READ, RTC_EPOCH_SET - Getting/Setting epoch Many RTCs encode the year in an 8-bit register which is either interpreted as an 8-bit binary number or as a BCD number. In both cases, the number is interpreted relative to this RTC's Epoch. The RTC's Epoch is initialized to 1900 on most systems but on Alpha and MIPS it might also be initialized to 1952, 1980, or 2000, depending on the value of an RTC register for the year. With some RTCs, these operations can be used to read or to set the RTC's Epoch, respectively. The third ioctl's argument is an unsigned long * or an unsigned long, respectively, and the value returned (or assigned) is the Epoch. To set the RTC's Epoch the process must be privileged (i.e., have the CAP_SYS_TIME capability). Implementation notes: All ioctls in this patch have a pointer to 'ulong' as their third argument. That is the reason why corresponding parts of added code in linux-user/syscall_defs.h contain special handling related to 'ulong' type: they use 'abi_ulong' type to make sure that ioctl's code is calculated correctly for both 32-bit and 64-bit targets. Also, 'MK_PTR(TYPE_ULONG)' is used for the similar reason in linux-user/ioctls.h.

linux-user: Add support for getting/setting RTC wakeup alarm using ioctls This patch implements functionalities of following ioctls: RTC_WKALM_SET, RTC_WKALM_GET - Getting/Setting wakeup alarm Some RTCs support a more powerful alarm interface, using these ioctls to read or write the RTC's alarm time (respectively) with this structure: struct rtc_wkalrm { unsigned char enabled; unsigned char pending; struct rtc_time time; }; The enabled flag is used to enable or disable the alarm interrupt, or to read its current status; when using these calls, RTC_AIE_ON and RTC_AIE_OFF are not used. 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. That is the reason why corresponding definition is added in linux-user/syscall_types.h. Since all elements of this structure are either of type 'unsigned char' or 'struct rtc_time' (that was covered in one of previous patches), the rest of the implementation is straightforward.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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'.

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.

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.

linux-user: Pass through nanosecond timestamp components for stat syscalls Since Linux 2.6 the stat syscalls have mostly supported nanosecond components for each of the file-related timestamps. QEMU user mode emulation currently does not pass through the nanosecond portion of the timestamp, even when the host system fills in the value. This results in a mismatch when run on subsecond resolution filesystems such as ext4 or XFS. An example of this leading to inconsistency is cross-debootstraping a full desktop root filesystem of Debian Buster. Recent versions of fontconfig store the full timestamp (instead of just the second portion) of the directory in its per-directory cache file, and checks this against the directory to see if the cache is up-to-date. With QEMU user mode emulation, the timestamp stored is incorrect, and upon booting the rootfs natively, fontconfig discovers the mismatch, and proceeds to rebuild the cache on the comparatively slow machine (low-power ARM vs x86). This stalls the first attempt to open whatever application that incorporates fontconfig. This patch renames the "unused" padding trailing each timestamp element to its nanosecond counterpart name if such an element exists in the kernel sources for the given platform. Not all do. Then have the syscall wrapper fill in the nanosecond portion if the host supports it, as specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros. Recent versions of glibc only use stat64 and newfstatat syscalls on 32-bit and 64-bit platforms respectively. The changes in this patch were tested by directly calling the stat, stat64 and newfstatat syscalls directly, in addition to the glibc wrapper, on arm and aarch64 little endian targets.

linux-user: Pass through nanosecond timestamp components for stat syscalls Since Linux 2.6 the stat syscalls have mostly supported nanosecond components for each of the file-related timestamps. QEMU user mode emulation currently does not pass through the nanosecond portion of the timestamp, even when the host system fills in the value. This results in a mismatch when run on subsecond resolution filesystems such as ext4 or XFS. An example of this leading to inconsistency is cross-debootstraping a full desktop root filesystem of Debian Buster. Recent versions of fontconfig store the full timestamp (instead of just the second portion) of the directory in its per-directory cache file, and checks this against the directory to see if the cache is up-to-date. With QEMU user mode emulation, the timestamp stored is incorrect, and upon booting the rootfs natively, fontconfig discovers the mismatch, and proceeds to rebuild the cache on the comparatively slow machine (low-power ARM vs x86). This stalls the first attempt to open whatever application that incorporates fontconfig. This patch renames the "unused" padding trailing each timestamp element to its nanosecond counterpart name if such an element exists in the kernel sources for the given platform. Not all do. Then have the syscall wrapper fill in the nanosecond portion if the host supports it, as specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros.

linux-user: Pass through nanosecond timestamp components for stat syscalls Since Linux 2.6 the stat syscalls have mostly supported nanosecond components for each of the file-related timestamps. QEMU user mode emulation currently does not pass through the nanosecond portion of the timestamp, even when the host system fills in the value. This results in a mismatch when run on subsecond resolution filesystems such as ext4 or XFS. An example of this leading to inconsistency is cross-debootstraping a full desktop root filesystem of Debian Buster. Recent versions of fontconfig store the full timestamp (instead of just the second portion) of the directory in its per-directory cache file, and checks this against the directory to see if the cache is up-to-date. With QEMU user mode emulation, the timestamp stored is incorrect, and upon booting the rootfs natively, fontconfig discovers the mismatch, and proceeds to rebuild the cache on the comparatively slow machine (low-power ARM vs x86). This stalls the first attempt to open whatever application that incorporates fontconfig. This patch renames the "unused" padding trailing each timestamp element to its nanosecond counterpart name if such an element exists in the kernel sources for the given platform. Not all do. Then have the syscall wrapper fill in the nanosecond portion if the host supports it, as specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros.

linux-user: Add support for getting/setting specified alsa timer parameters using ioctls This patch implements functionalities of following ioctls: SNDRV_TIMER_IOCTL_GINFO - Getting information about specified timer Read information about the specified timer. The information about the timer is returned in the following structure: struct snd_timer_ginfo { struct snd_timer_id tid; /* requested timer ID */ unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* */ int card; /* card number */ unsigned char id[64]; /* timer identification */ unsigned char name[80]; /* timer name */ unsigned long reserved0; /* reserved for future use */ unsigned long resolution; /* average period resolution in ns */ unsigned long resolution_min; /* minimal period resolution in ns */ unsigned long resolution_max; /* maximal period resolution in ns */ unsigned int clients; /* active timer clients */ unsigned char reserved[32]; /* reserved */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which information is to be obtained. After the ioctl call, the rest of the structure fields are filled with values from the timer device with the specified id. If there is no device with the specified id, the error ENODEV ("No such device") is returned. SNDRV_TIMER_IOCTL_GPARAMS - Setting precise period duration Sets timer precise period duration numerator and denominator in seconds. The period duration is set in the following structure: struct snd_timer_gparams { struct snd_timer_id tid; /* requested timer ID */ unsigned long period_num; /* period duration - numerator */ unsigned long period_den; /* period duration - denominator */ unsigned char reserved[32]; /* reserved */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which period duration is to be set. Also, the fileds "period_num" and "period_den" should be filled with the period duration numerator and denominator values that are to be set respectively. If there is no device with the specified id, the error ENODEV ("No such device") is returned. SNDRV_TIMER_IOCTL_GSTATUS - Getting current period resolution Read timer current period resolution in nanoseconds and period resolution numerator and denominator in seconds. The period resolution information is returned in the following structure: struct snd_timer_gstatus { struct snd_timer_id tid; /* requested timer ID */ unsigned long resolution; /* current period resolution in ns */ unsigned long resolution_num; /* period resolution - numerator */ unsigned long resolution_den; /* period resolution - denominator */ unsigned char reserved[32]; /* reserved for future use */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which period resolution is to be obtained. After the ioctl call, the rest of the structure fields are filled with values from the timer device with the specified id. If there is no device with the specified id, the error ENODEV ("No such device") is returned. 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'. All of these strcutures 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'. Also, all of the structures have a field with type 'struct snd_timer_id' which is the reason why a separate target structure 'struct target_snd_timer_id' was also defined. The rest of the implementation was straightforward.

Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer which information is to be obtained.

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.

Implementation notes: All ioctls in this patch have pointer to some kind of a structure as their third argument.

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 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.

Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which information is to be obtained. After the ioctl call, the rest of the structure fields are filled with values from the timer device with the specified id. If there is no device with the specified id, the error ENODEV ("No such device") is returned. SNDRV_TIMER_IOCTL_GPARAMS - Setting precise period duration Sets timer precise period duration numerator and denominator in seconds. The period duration is set in the following structure: struct snd_timer_gparams { struct snd_timer_id tid; /* requested timer ID */ unsigned long period_num; /* period duration - numerator */ unsigned long period_den; /* period duration - denominator */ unsigned char reserved[32]; /* reserved */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which period duration is to be set. Also, the fileds "period_num" and "period_den" should be filled with the period duration numerator and denominator values that are to be set respectively. If there is no device with the specified id, the error ENODEV ("No such device") is returned. SNDRV_TIMER_IOCTL_GSTATUS - Getting current period resolution Read timer current period resolution in nanoseconds and period resolution numerator and denominator in seconds. The period resolution information is returned in the following structure: struct snd_timer_gstatus { struct snd_timer_id tid; /* requested timer ID */ unsigned long resolution; /* current period resolution in ns */ unsigned long resolution_num; /* period resolution - numerator */ unsigned long resolution_den; /* period resolution - denominator */ unsigned char reserved[32]; /* reserved for future use */ }; A pointer to this structure should be passed as the third ioctl's argument. Before calling the ioctl, the field "tid" should be initialized with the id information for the timer which period resolution is to be obtained. After the ioctl call, the rest of the structure fields are filled with values from the timer device with the specified id.

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'. All of these strcutures 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'. Also, all of the structures have a field with type 'struct snd_timer_id' which is the reason why a separate target structure 'struct target_snd_timer_id' was also defined.

linux-user: Fix syslog() syscall support There are currently several problems related to syslog() support. For example, if the second argument "bufp" of target syslog() syscall is NULL, the current implementation always returns error code EFAULT. However, NULL is a perfectly valid value for the second argument for many use cases of this syscall. This is, for example, visible from this excerpt of man page for syslog(2): > EINVAL Bad arguments (e.g., bad type; or for type 2, 3, or 4, buf is > NULL, or len is less than zero; or for type 8, the level is > outside the range 1 to 8). Moreover, the argument "bufp" is ignored for all cases of values of the first argument, except 2, 3 and 4. This means that for such cases (the first argument is not 2, 3 or 4), there is no need to pass "buf" between host and target, and it can be set to NULL while calling host's syslog(), without loss of emulation accuracy. Note also that if "bufp" is NULL and the first argument is 2, 3 or 4, the correct returned error code is EINVAL, not EFAULT. All these details are reflected in this patch. "#ifdef TARGET_NR_syslog" is also proprerly inserted when needed. Support for Qemu's "-strace" switch for syslog() syscall is included too. LTP tests syslog11 and syslog12 pass with this patch (while fail without it), on any platform. Changes to original patch by Riku Voipio: fixed error paths in TARGET_SYSLOG_ACTION_READ_ALL to match http://lxr.free-electrons.com/source/kernel/printk/printk.c?v=4.7#L1335 Should fix also the build error in: https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg03721.html Signed-off-by: Aleksandar Markovic <aleksandar.markovic@imgtec.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

linux-user: Add support for translation of statx() syscall Implement support for translation of system call statx(). The implementation is based on "best effort" approach: if host is capable of executing statx(), host statx() is used. If not, the implementation includes invoking a more mature system call fstatat() on the host side to achieve as close as possible functionality. Support for statx() in kernel and glibc was, however, introduced at different points of time (the difference is more than a year): - kernel: Linux 4.11 (30 April 2017) - glibc: glibc 2.28 (1 Aug 2018) In this patch, the availability of statx() support is established via __NR_statx (if it is defined, statx() is considered available). This coincedes with statx() introduction in kernel. However, the structure statx definition may not be available in any header for hosts with glibc older than 2.28 (and it is, by design, to be defined in one of glibc headers), even though the full statx() functionality may be supported in kernel. Hence, a structure "target_statx" is defined in this patch, to remove that dependency on glibc headers, and to use statx() functionality as soon as the host kernel is capable of supporting it. Such statx structure definition is used for both target and host structures statx (of course, this doesn't mean the endian arrangement is the same on target and host - the endian conversion is done in all necessary cases).
