* linux-user: strace now handles unshare syscall args correctlyMatus Kysel2021-05-151-1/+1
| | | | | | | | | | Syscall unshare did not have custom print function for strace, but it's argument is same as flags in clone syscall, so it can be easily implemented. Also updated missing flags from clone_flags.

* linux-user: Add strace support for printing arguments of some clock and time ↵Filip Bozuta2020-08-271-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions This patch implements strace argument printing functionality for following syscalls: * clock_getres, clock_gettime, clock_settime - clock and time functions int clock_getres(clockid_t clockid, struct timespec *res) int clock_gettime(clockid_t clockid, struct timespec *tp) int clock_settime(clockid_t clockid, const struct timespec *tp) man page: https://man7.org/linux/man-pages/man2/clock_getres.2.html * gettimeofday - get time int gettimeofday(struct timeval *tv, struct timezone *tz) man page: https://man7.org/linux/man-pages/man2/gettimeofday.2.html * getitimer, setitimer - get or set value of an interval timer int getitimer(int which, struct itimerval *curr_value) int setitimer(int which, const struct itimerval *new_value, struct itimerval *old_value) man page: https://man7.org/linux/man-pages/man2/getitimer.2.html Implementation notes: All of the syscalls have some structue types as argument types and thus a separate printing function was stated in file "strace.list" for each of them. All of these functions use existing functions for their appropriate structure types ("print_timeval()" and "print_timezone()"). Functions "print_timespec()" and "print_itimerval()" were added in this patch so that they can be used to print types "struct timespec" and "struct itimerval" used by some of the syscalls. Function "print_itimerval()" uses the existing function "print_timeval()" to print fields of the structure "struct itimerval" that are of type "struct timeval". Function "print_enums()", which was introduced in the previous patch, is used to print the interval timer type which is the first argument of "getitimer()" and "setitimer()". Also, this function is used to print the clock id which is the first argument of "clock_getres()" and "clock_gettime()". For that reason, the existing function "print_clockid()" was removed in this patch. Existing function "print_clock_adjtime()" was also changed for this reason to use "print_enums()". The existing function "print_timeval()" was changed a little so that it prints the field names beside the values. Syscalls "clock_getres()" and "clock_gettime()" have the same number and types of arguments and thus their print functions "print_clock_getres" and "print_clock_gettime" share a common definition in file "strace.c".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lock and unlock memory This patch implements strace argument printing functionality for following syscalls: * mlock, munlock, mlockall, munlockall - lock and unlock memory int mlock(const void *addr, size_t len) int munlock(const void *addr, size_t len) int mlockall(int flags) int munlockall(void) man page: https://man7.org/linux/man-pages/man2/mlock.2.html Implementation notes: Syscall mlockall() takes an argument that is composed of predefined values which represent flags that determine the type of locking operation that is to be performed. For that reason, a printing function "print_mlockall" was stated in file "strace.list". This printing function uses an already existing function "print_flags()" to print the "flags" argument. These flags are stated inside an array "mlockall_flags" that contains values of type "struct flags". These values are instantiated using an existing macro "FLAG_TARGET()" that crates aproppriate target flag values based on those defined in files '/target_syscall.h'. These target flag values were changed from "TARGET_MLOCKALL_MCL*" to "TARGET_MCL_*" so that they can be aproppriately set and recognised in "strace.c" with "FLAG_TARGET()". Value for "MCL_ONFAULT" was added in this patch. This value was also added in "syscall.c" in function "target_to_host_mlockall_arg()". Because this flag value was added in kernel version 4.4, it is enwrapped in an #ifdef directive (both in "syscall.c" and in "strace.c") as to support older kernel versions. The other syscalls have only primitive argument types, so the rest of the implementation was handled by stating an appropriate printing format in file "strace.list". Syscall mlock2() is not implemented in "syscall.c" and thus it's argument printing is not implemented in this patch.

This function is defined and implemented in "strace.c" by using an existing function used to print string arguments: "print_string()". For syscall ftruncate64, a separate printing function was also stated in "strace.c" as it requires a special kind of handling. The other syscalls have only primitive argument types, so the rest of the implementation was handled by stating an appropriate printing format in file "strace.list". Function "regpairs_aligned()" was cut & pasted from "syscall.c" to "qemu.h" as it is used by functions "print_truncate64()" and "print_ftruncate64()" to print the offset arguments of "truncate64()" and "ftruncate64()".

* linux-user: Add strace support for printing arguments of ioctl()Filip Bozuta2020-07-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements functionality for strace argument printing for ioctls. When running ioctls through qemu with "-strace", they get printed in format: "ioctl(fd_num,0x*,0x*) = ret_value" where the request code an the ioctl's third argument get printed in a hexadicemal format. This patch changes that by enabling strace to print both the request code name and the contents of the third argument. For example, when running ioctl RTC_SET_TIME with "-strace", with changes from this patch, it gets printed in this way: "ioctl(3,RTC_SET_TIME,{12,13,15,20,10,119,0,0,0}) = 0" In case of IOC_R type ioctls, the contents of the third argument get printed after the return value, and the argument inside the ioctl call gets printed as pointer in hexadecimal format. For example, when running RTC_RD_TIME with "-strace", with changes from this patch, it gets printed in this way: "ioctl(3,RTC_RD_TIME,0x40800374) = 0 ({22,9,13,11,5,120,0,0,0})" In case of IOC_RW type ioctls, the contents of the third argument get printed both inside the ioctl call and after the return value. Implementation notes: Functions "print_ioctl()" and "print_syscall_ret_ioctl()", that are defined in "strace.c", are listed in file "strace.list" as "call" and "result" value for ioctl. Structure definition "IOCTLEntry" as well as predefined values for IOC_R, IOC_W and IOC_RW were cut and pasted from file "syscall.c" to file "qemu.h" so that they can be used by these functions to print the contents of the third ioctl argument. Also, the "static" identifier for array "ioctl_entries[]" was removed and this array was declared as "extern" in "qemu.h" so that it can also be used by these functions. To decode the structure type of the ioctl third argument, function "thunk_print()" was defined in file "thunk.c" and its definition is somewhat simillar to that of function "thunk_convert()".

* linux-user: Add strace support for printing arguments of fallocate()Filip Bozuta2020-06-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements strace argument printing functionality for following syscall: *fallocate - manipulate file space int fallocate(int fd, int mode, off_t offset, off_t len) man page: https://www.man7.org/linux/man-pages/man2/fallocate.2.html Implementation notes: This syscall's second argument "mode" is composed of predefined values which represent flags that determine the type of operation that is to be performed on the file space. For that reason, a printing function "print_fallocate" was stated in file "strace.list". This printing function uses an already existing function "print_flags()" to print flags of the "mode" argument. These flags are stated inside an array "falloc_flags" that contains values of type "struct flags". These values are instantiated using an existing macro "FLAG_GENERIC()". Most of these flags are defined after kernel version 3.0 which is why they are enwrapped in an #ifdef directive. The syscall's third ant fourth argument are of type "off_t" which can cause variations between 32/64-bit architectures. To handle this variation, function "target_offset64()" was copied from file "strace.c" and used in "print_fallocate" to print "off_t" arguments for 32-bit architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements strace argument printing functionality for syscalls: *chown, lchown - change ownership of a file int chown(const char *pathname, uid_t owner, gid_t group) int lchown(const char *pathname, uid_t owner, gid_t group) man page: https://www.man7.org/linux/man-pages/man2/lchown.2.html Implementation notes: Both syscalls use strings as arguments and thus a separate printing function was stated in "strace.list" for them. Both syscalls share the same number and types of arguments and thus share a same definition in file "syscall.c". This defintion uses existing functions "print_string()" to print the string argument and "print_raw_param()" to print other two arguments that are of basic types.

This function is defined in "strace.c" by using an existing function "print_raw_param()" to print the first and second argument and a switch(case) statement for the predefined values of the third argument. Values "SEEK_DATA" and "SEEK_HOLE" are defined in kernel version 3.1. That is the reason why case statements for these values are enwrapped in #ifdef directive.

* linux-user: Fix syslog() syscall supportAleksandar Markovic2016-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 adjtimex() syscallAleksandar Markovic2016-10-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements Qemu user mode adjtimex() syscall support. Syscall adjtimex() reads and optionally sets parameters for a clock adjustment algorithm used in network synchonization or similar scenarios. Its declaration is: int adjtimex(struct timex *buf); The correspondent source code in the Linux kernel is at kernel/time.c, line 206. The Qemu implementation is based on invocation of host's adjtimex(), and its key part is in the "TARGET_NR_adjtimex" case segment of the the main switch statement of the function do_syscall(), in linux-user/syscalls.c. All necessary conversions of the data structures from target to host and from host to target are covered. Two new functions, target_to_host_timex() and host_to_target_timex(), are provided for the purpose of such conversions. For that purpose, the support for related structure "timex" had tp be added to the file linux-user/syscall_defs.h, based on its definition in Linux kernel. Also, the relevant support for "-strace" Qemu option is included in files linux-user/strace.c and linux-user/strace.list. This patch also fixes failures of LTP tests adjtimex01 and adjtimex02, if executed in Qemu user mode.

| | | | | | | | | | | | | | | It has been pointed out on LKML that the alpha umount syscall numbers are named wrong, and a patch to rectify that has been posted for 3.11. Glibc works around this by treating NR_umount as NR_umount2 if NR_oldumount exists. That's more complicated than we need in QEMU, given that we control linux-user/*/syscall_nr.h. This is the last instance of TARGET_NR_oldumount, so delete that from the strace.list. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>

So move the four QEMU target architectures (arm, i386, sparc, unicore32) which were defining TARGET_NR_pread/pwrite to define TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite implementation code completely.
