1/* 2 * See i386-fbsd.c for copyright and license terms. 3 * 4 * System call arguments come in several flavours: 5 * Hex -- values that should be printed in hex (addresses) 6 * Octal -- Same as above, but octal 7 * Int -- normal integer values (file descriptors, for example) 8 * LongHex -- long value that should be printed in hex 9 * Name -- pointer to a NULL-terminated string. 10 * BinString -- pointer to an array of chars, printed via strvisx(). 11 * Ptr -- pointer to some unspecified structure. Just print as hex for now. 12 * Stat -- a pointer to a stat buffer. Prints a couple fields. 13 * StatFs -- a pointer to a statfs buffer. Prints a few fields. 14 * Ioctl -- an ioctl command. Woefully limited. 15 * Quad -- a double-word value. e.g., lseek(int, offset_t, int) 16 * Signal -- a signal number. Prints the signal name (SIGxxx) 17 * Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port 18 * StringArray -- a pointer to an array of string pointers. 19 * Timespec -- a pointer to a struct timespec. Prints both elements. 20 * Timeval -- a pointer to a struct timeval. Prints both elements. 21 * Timeval2 -- a pointer to two struct timevals. Prints both elements of both. 22 * Itimerval -- a pointer to a struct itimerval. Prints all elements. 23 * Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events. 24 * Fd_set -- a pointer to an array of fd_set. Prints the fds that are set. 25 * Sigaction -- a pointer to a struct sigaction. Prints all elements. 26 * Umtx -- a pointer to a struct umtx. Prints the value of owner. 27 * Sigset -- a pointer to a sigset_t. Prints the signals that are set. 28 * Sigprocmask -- the first argument to sigprocmask(). Prints the name. 29 * Kevent -- a pointer to an array of struct kevents. Prints all elements. 30 * Pathconf -- the 2nd argument of pathconf(). 31 * 32 * In addition, the pointer types (String, Ptr) may have OUT masked in -- 33 * this means that the data is set on *return* from the system call -- or 34 * IN (meaning that the data is passed *into* the system call). 35 */ 36/* 37 * $FreeBSD: stable/10/usr.bin/truss/syscall.h 294033 2016-01-14 19:47:52Z jhb $ 38 */ 39 40enum Argtype { None = 1, Hex, Octal, Int, LongHex, Name, Ptr, Stat, Ioctl, Quad, 41 Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, Pollfd, 42 Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 43 Umtx, Sigset, Sigprocmask, StatFs, Kevent, Sockdomain, Socktype, Open, 44 Fcntlflag, Rusage, BinString, Shutdown, Resource, Rlimit, Timeval2, 45 Pathconf, Rforkflags, ExitStatus, Waitoptions, Idtype, Procctl, 46 LinuxSockArgs, Umtxop, Atfd, Atflags, Timespec2, Accessmode, Long, 47 Sysarch, ExecArgs, ExecEnv, PipeFds, QuadHex }; 48 49#define ARG_MASK 0xff 50#define OUT 0x100 51#define IN /*0x20*/0 52 53struct syscall_args { 54 enum Argtype type; 55 int offset; 56}; 57 58struct syscall { 59 STAILQ_ENTRY(syscall) entries; 60 const char *name; 61 u_int ret_type; /* 0, 1, or 2 return values */ 62 u_int nargs; /* actual number of meaningful arguments */ 63 /* Hopefully, no syscalls with > 10 args */ 64 struct syscall_args args[10]; 65 struct timespec time; /* Time spent for this call */ 66 int ncalls; /* Number of calls */ 67 int nerror; /* Number of calls that returned with error */ 68}; 69 70struct syscall *get_syscall(const char *, int nargs); 71char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 72 73/* 74 * Linux Socket defines 75 */ 76#define LINUX_SOCKET 1 77#define LINUX_BIND 2 78#define LINUX_CONNECT 3 79#define LINUX_LISTEN 4 80#define LINUX_ACCEPT 5 81#define LINUX_GETSOCKNAME 6 82#define LINUX_GETPEERNAME 7 83#define LINUX_SOCKETPAIR 8 84#define LINUX_SEND 9 85#define LINUX_RECV 10 86#define LINUX_SENDTO 11 87#define LINUX_RECVFROM 12 88#define LINUX_SHUTDOWN 13 89#define LINUX_SETSOCKOPT 14 90#define LINUX_GETSOCKOPT 15 91#define LINUX_SENDMSG 16 92#define LINUX_RECVMSG 17 93 94#define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 95 0 : sizeof(register_t) - sizeof(t)) 96 97#if BYTE_ORDER == LITTLE_ENDIAN 98#define PADL_(t) 0 99#define PADR_(t) PAD_(t) 100#else 101#define PADL_(t) PAD_(t) 102#define PADR_(t) 0 103#endif 104 105typedef int l_int; 106typedef uint32_t l_ulong; 107 108struct linux_socketcall_args { 109 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 110 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 111}; 112 113void init_syscalls(void); 114void print_syscall(struct trussinfo *, const char *, int, char **); 115void print_syscall_ret(struct trussinfo *, const char *, int, char **, int, 116 long *, struct syscall *); 117void print_summary(struct trussinfo *trussinfo); 118
