Just print as hex for now. 45 * Stat -- a pointer to a stat buffer. Prints a couple fields. 46 * Stat11 -- a pointer to a freebsd 11 stat buffer. Prints a couple fields. 47 * StatFs -- a pointer to a statfs buffer. Prints a few fields. 48 * Ioctl -- an ioctl command. Woefully limited. 49 * Quad -- a double-word value. e.g., lseek(int, offset_t, int) 50 * Signal -- a signal number. Prints the signal name (SIGxxx) 51 * Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port 52 * StringArray -- a pointer to an array of string pointers. 53 * Timespec -- a pointer to a struct timespec. Prints both elements. 54 * Timeval -- a pointer to a struct timeval. Prints both elements. 55 * Timeval2 -- a pointer to two struct timevals. Prints both elements of both. 56 * Itimerval -- a pointer to a struct itimerval. Prints all elements. 57 * Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events. 58 * Fd_set -- a pointer to an array of fd_set. Prints the fds that are set. 59 * Sigaction -- a pointer to a struct sigaction. Prints all elements. 60 * Sigset -- a pointer to a sigset_t. Prints the signals that are set. 61 * Sigprocmask -- the first argument to sigprocmask(). Prints the name. 62 * Kevent -- a pointer to an array of struct kevents. Prints all elements. 63 * Pathconf -- the 2nd argument of pathconf(). 64 * Utrace -- utrace(2) buffer. 65 * CapRights -- a pointer to a cap_rights_t. Prints all set capabilities. 66 * 67 * In addition, the pointer types (String, Ptr) may have OUT masked in -- 68 * this means that the data is set on *return* from the system call -- or 69 * IN (meaning that the data is passed *into* the system call). 70 */ 71 72 enum Argtype { None = 1, Hex, Octal, Int, UInt, LongHex, Name, Ptr, Stat, Stat11, Ioctl, 73 Quad, Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, 74 Pollfd, Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 75 Sigset, Sigprocmask, StatFs, Kevent, Sockdomain, Socktype, Open, 76 Fcntlflag, Rusage, RusageWho, BinString, Shutdown, Resource, Rlimit, 77 Timeval2, Pathconf, Rforkflags, ExitStatus, Waitoptions, Idtype, Procctl, 78 LinuxSockArgs, Umtxop, Atfd, Atflags, Timespec2, Accessmode, Long, 79 Sysarch, ExecArgs, ExecEnv, PipeFds, QuadHex, Utrace, IntArray, Pipe2, 80 CapFcntlRights, Fadvice, FileFlags, Flockop, Getfsstatmode, Kldsymcmd, 81 Kldunloadflags, Sizet, Madvice, Socklent, Sockprotocol, Sockoptlevel, 82 Sockoptname, Msgflags, CapRights, PUInt, PQuadHex, Acltype, 83 Extattrnamespace, Minherit, Mlockall, Mountflags, Msync, Priowhich, 84 Ptraceop, Quotactlcmd, Reboothowto, Rtpriofunc, Schedpolicy, Schedparam, 85 PSig, Siginfo, Kevent11, 86 87 CloudABIAdvice, CloudABIClockID, ClouduABIFDSFlags, 88 CloudABIFDStat, CloudABIFileStat, CloudABIFileType, 89 CloudABIFSFlags, CloudABILookup, CloudABIMFlags, CloudABIMProt, 90 CloudABIMSFlags, CloudABIOFlags, CloudABISDFlags, 91 CloudABISignal, CloudABISockStat, CloudABISSFlags, 92 CloudABITimestamp, CloudABIULFlags, CloudABIWhence }; 93 94 #define ARG_MASK 0xff 95 #define OUT 0x100 96 #define IN /*0x20*/0 97 98 struct syscall_args { 99 enum Argtype type; 100 int offset; 101 }; 102 103 struct syscall { 104 STAILQ_ENTRY(syscall) entries; 105 const char *name; 106 u_int ret_type; /* 0, 1, or 2 return values */ 107 u_int nargs; /* actual number of meaningful arguments */ 108 /* Hopefully, no syscalls with > 10 args */ 109 struct syscall_args args[10]; 110 struct timespec time; /* Time spent for this call */ 111 int ncalls; /* Number of calls */ 112 int nerror; /* Number of calls that returned with error */ 113 bool unknown; /* Unknown system call */ 114 }; 115 116 struct syscall *get_syscall(struct threadinfo *, u_int, u_int); 117 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 118 119 /* 120 * Linux Socket defines 121 */ 122 #define LINUX_SOCKET 1 123 #define LINUX_BIND 2 124 #define LINUX_CONNECT 3 125 #define LINUX_LISTEN 4 126 #define LINUX_ACCEPT 5 127 #define LINUX_GETSOCKNAME 6 128 #define LINUX_GETPEERNAME 7 129 #define LINUX_SOCKETPAIR 8 130 #define LINUX_SEND 9 131 #define LINUX_RECV 10 132 #define LINUX_SENDTO 11 133 #define LINUX_RECVFROM 12 134 #define LINUX_SHUTDOWN 13 135 #define LINUX_SETSOCKOPT 14 136 #define LINUX_GETSOCKOPT 15 137 #define LINUX_SENDMSG 16 138 #define LINUX_RECVMSG 17 139 140 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 141 0 : sizeof(register_t) - sizeof(t)) 142 143 #if BYTE_ORDER == LITTLE_ENDIAN 144 #define PADL_(t) 0 145 #define PADR_(t) PAD_(t) 146 #else 147 #define PADL_(t) PAD_(t) 148 #define PADR_(t) 0 149 #endif 150 151 typedef int l_int; 152 typedef uint32_t l_ulong; 153 154 struct linux_socketcall_args { 155 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 156 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 157 }; 158 159 void init_syscalls(void); 160 void print_syscall(struct trussinfo *); 161 void print_syscall_ret(struct trussinfo *, int, long *); 162 void print_summary(struct trussinfo *trussinfo); 163
