The last field of this structure "result" represents the calling function that prints the return values. This field was extended in this patch so that this function takes all syscalls arguments beside the return value. In this way, it enables "-strace" to print arguments of syscalls that have changed after the syscall execution. This extension will be useful as there are many syscalls that return values inside their arguments (i.e. listxattr() that returns the list of extended attributes inside the "list" argument). Implementation notes: Since there are already three existing "print_syscall_ret*" functions inside "strace.c" ("print_syscall_ret_addr()", "print_syscall_ret_adjtimex()", "print_syscall_ret_newselect()"), they were changed to have all syscall arguments beside the return value. This was done so that these functions don't cause build errors (even though syscall arguments are not used in these functions). There is code repetition in these functions for checking the return value and printing the approppriate error message (this code is also located in print_syscall_ret() at the end of "strace.c"). That is the reason why a function "syscall_print_err()" was added for this code and put inside these functions. Functions "print_newselect()" and "print_syscall_ret_newselect()" were changed to use this new implemented functionality and not store the syscall argument values in separate static variables.

This function is defined and implemented in "strace.c" by using an existing function used to print string arguments: "print_string()". All 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".

All of these printing functions were defined in "strace.c" using existing printing functions for appropriate argument types: "print_string()" - for (const char*) type "print_pointer()" - for (char*) and (void *) type "print_raw_param()" for (int) and (size_t) type Syscalls "getxattr()" and "lgetxattr()" have the same number and type of arguments and thus their print functions ("print_getxattr", "print_lgetxattr") share a same definition. The same statement applies to syscalls "listxattr()" and "llistxattr()". Function "print_syscall_ret_listxattr()" was added to print the returned list of extended attributes for syscalls "print_listxattr(), print_llistxattr() and print_flistxattr()".

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.

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.

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.

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()".
