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 * Sigset -- a pointer to a sigset_t. Prints the signals that are set. 27 * Sigprocmask -- the first argument to sigprocmask(). Prints the name. 28 * Kevent -- a pointer to an array of struct kevents. Prints all elements. 29 * Pathconf -- the 2nd argument of pathconf(). 30 * 31 * In addition, the pointer types (String, Ptr) may have OUT masked in -- 32 * this means that the data is set on *return* from the system call -- or 33 * IN (meaning that the data is passed *into* the system call). 34 */ 35 /* 36 * $FreeBSD$ 37 */ 38 39 enum Argtype { None = 1, Hex, Octal, Int, LongHex, Name, Ptr, Stat, Ioctl, Quad, 40 Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, Pollfd, 41 Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 42 Sigset, Sigprocmask, StatFs, Kevent, Sockdomain, Socktype, Open, 43 Fcntlflag, Rusage, BinString, Shutdown, Resource, Rlimit, Timeval2, 44 Pathconf, Rforkflags, ExitStatus, Waitoptions, Idtype, Procctl, 45 LinuxSockArgs, Umtxop, Atfd, Atflags, Timespec2, Accessmode, Long, 46 Sysarch, ExecArgs, ExecEnv, PipeFds, QuadHex }; 47 48 #define ARG_MASK 0xff 49 #define OUT 0x100 50 #define IN /*0x20*/0 51 52 struct syscall_args { 53 enum Argtype type; 54 int offset; 55 }; 56 57 struct syscall { 58 STAILQ_ENTRY(syscall) entries; 59 const char *name; 60 u_int ret_type; /* 0, 1, or 2 return values */ 61 u_int nargs; /* actual number of meaningful arguments */ 62 /* Hopefully, no syscalls with > 10 args */ 63 struct syscall_args args[10]; 64 struct timespec time; /* Time spent for this call */ 65 int ncalls; /* Number of calls */ 66 int nerror; /* Number of calls that returned with error */ 67 }; 68 69 struct syscall *get_syscall(const char *, int nargs); 70 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 71 72 /* 73 * Linux Socket defines 74 */ 75 #define LINUX_SOCKET 1 76 #define LINUX_BIND 2 77 #define LINUX_CONNECT 3 78 #define LINUX_LISTEN 4 79 #define LINUX_ACCEPT 5 80 #define LINUX_GETSOCKNAME 6 81 #define LINUX_GETPEERNAME 7 82 #define LINUX_SOCKETPAIR 8 83 #define LINUX_SEND 9 84 #define LINUX_RECV 10 85 #define LINUX_SENDTO 11 86 #define LINUX_RECVFROM 12 87 #define LINUX_SHUTDOWN 13 88 #define LINUX_SETSOCKOPT 14 89 #define LINUX_GETSOCKOPT 15 90 #define LINUX_SENDMSG 16 91 #define LINUX_RECVMSG 17 92 93 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 94 0 : sizeof(register_t) - sizeof(t)) 95 96 #if BYTE_ORDER == LITTLE_ENDIAN 97 #define PADL_(t) 0 98 #define PADR_(t) PAD_(t) 99 #else 100 #define PADL_(t) PAD_(t) 101 #define PADR_(t) 0 102 #endif 103 104 typedef int l_int; 105 typedef uint32_t l_ulong; 106 107 struct linux_socketcall_args { 108 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 109 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 110 }; 111 112 void init_syscalls(void); 113 void print_syscall(struct trussinfo *, const char *, int, char **); 114 void print_syscall_ret(struct trussinfo *, const char *, int, char **, int, 115 long *, struct syscall *); 116 void print_summary(struct trussinfo *trussinfo); 117
