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 * Utrace -- utrace(2) buffer. 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 * $FreeBSD$ 38 */ 39 40 enum Argtype { None = 1, Hex, Octal, Int, UInt, LongHex, Name, Ptr, Stat, Ioctl, 41 Quad, Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, 42 Pollfd, Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 43 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, Utrace, IntArray, Pipe2, 48 49 CloudABIAdvice, CloudABIClockID, ClouduABIFDSFlags, 50 CloudABIFDStat, CloudABIFileStat, CloudABIFileType, 51 CloudABIFSFlags, CloudABILookup, CloudABIMFlags, CloudABIMProt, 52 CloudABIMSFlags, CloudABIOFlags, CloudABISDFlags, 53 CloudABISignal, CloudABISockStat, CloudABISSFlags, 54 CloudABITimestamp, CloudABIULFlags, CloudABIWhence }; 55 56 #define ARG_MASK 0xff 57 #define OUT 0x100 58 #define IN /*0x20*/0 59 60 struct syscall_args { 61 enum Argtype type; 62 int offset; 63 }; 64 65 struct syscall { 66 STAILQ_ENTRY(syscall) entries; 67 const char *name; 68 u_int ret_type; /* 0, 1, or 2 return values */ 69 u_int nargs; /* actual number of meaningful arguments */ 70 /* Hopefully, no syscalls with > 10 args */ 71 struct syscall_args args[10]; 72 struct timespec time; /* Time spent for this call */ 73 int ncalls; /* Number of calls */ 74 int nerror; /* Number of calls that returned with error */ 75 bool unknown; /* Unknown system call */ 76 }; 77 78 struct syscall *get_syscall(struct threadinfo *, u_int, u_int); 79 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 80 81 /* 82 * Linux Socket defines 83 */ 84 #define LINUX_SOCKET 1 85 #define LINUX_BIND 2 86 #define LINUX_CONNECT 3 87 #define LINUX_LISTEN 4 88 #define LINUX_ACCEPT 5 89 #define LINUX_GETSOCKNAME 6 90 #define LINUX_GETPEERNAME 7 91 #define LINUX_SOCKETPAIR 8 92 #define LINUX_SEND 9 93 #define LINUX_RECV 10 94 #define LINUX_SENDTO 11 95 #define LINUX_RECVFROM 12 96 #define LINUX_SHUTDOWN 13 97 #define LINUX_SETSOCKOPT 14 98 #define LINUX_GETSOCKOPT 15 99 #define LINUX_SENDMSG 16 100 #define LINUX_RECVMSG 17 101 102 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 103 0 : sizeof(register_t) - sizeof(t)) 104 105 #if BYTE_ORDER == LITTLE_ENDIAN 106 #define PADL_(t) 0 107 #define PADR_(t) PAD_(t) 108 #else 109 #define PADL_(t) PAD_(t) 110 #define PADR_(t) 0 111 #endif 112 113 typedef int l_int; 114 typedef uint32_t l_ulong; 115 116 struct linux_socketcall_args { 117 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 118 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 119 }; 120 121 void init_syscalls(void); 122 void print_syscall(struct trussinfo *); 123 void print_syscall_ret(struct trussinfo *, int, long *); 124 void print_summary(struct trussinfo *trussinfo); 125
