This patch implements strace argument printing functionality for following syscalls:
*getxattr, lgetxattr, fgetxattr - retrieve an extended attribute value
ssize_t getxattr(const char *path, const char *name, void *value, size_t size)
ssize_t lgetxattr(const char *path, const char *name, void *value, size_t size)
ssize_t fgetxattr(int fd, const char *name, void *value, size_t size)
man page: https://www.man7.org/linux/man-pages/man2/getxattr.2.html
*listxattr, llistxattr, flistxattr - list extended attribute names
ssize_t listxattr(const char *path, char *list, size_t size)
ssize_t llistxattr(const char *path, char *list, size_t size)
ssize_t flistxattr(int fd, char *list, size_t size)
man page: https://www.man7.org/linux/man-pages/man2/listxattr.2.html
*removexattr, lremovexattr, fremovexattr - remove an extended attribute
int removexattr(const char *path, const char *name)
int lremovexattr(const char *path, const char *name)
int fremovexattr(int fd, const char *name)
man page: https://www.man7.org/linux/man-pages/man2/removexattr.2.html
Implementation notes:
All of the syscalls have strings as argument types and thus a separate
printing function was stated in file "strace.list" for every one of them.
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()".
