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 * CapRights -- a pointer to a cap_rights_t. Prints all set capabilities. 32 * 33 * In addition, the pointer types (String, Ptr) may have OUT masked in -- 34 * this means that the data is set on *return* from the system call -- or 35 * IN (meaning that the data is passed *into* the system call). 36 */ 37 /* 38 * $FreeBSD$ 39 */ 40 41 enum Argtype { None = 1, Hex, Octal, Int, UInt, LongHex, Name, Ptr, Stat, Ioctl, 42 Quad, Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, 43 Pollfd, Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 44 Sigset, Sigprocmask, StatFs, Kevent, Sockdomain, Socktype, Open, 45 Fcntlflag, Rusage, BinString, Shutdown, Resource, Rlimit, Timeval2, 46 Pathconf, Rforkflags, ExitStatus, Waitoptions, Idtype, Procctl, 47 LinuxSockArgs, Umtxop, Atfd, Atflags, Timespec2, Accessmode, Long, 48 Sysarch, ExecArgs, ExecEnv, PipeFds, QuadHex, Utrace, IntArray, Pipe2, 49 CapFcntlRights, Fadvice, FileFlags, Flockop, Getfsstatmode, Kldsymcmd, 50 Kldunloadflags, Sizet, Madvice, Socklent, Sockprotocol, Sockoptlevel, 51 Sockoptname, Msgflags, CapRights, PUInt, 52 53 CloudABIAdvice, CloudABIClockID, ClouduABIFDSFlags, 54 CloudABIFDStat, CloudABIFileStat, CloudABIFileType, 55 CloudABIFSFlags, CloudABILookup, CloudABIMFlags, CloudABIMProt, 56 CloudABIMSFlags, CloudABIOFlags, CloudABISDFlags, 57 CloudABISignal, CloudABISockStat, CloudABISSFlags, 58 CloudABITimestamp, CloudABIULFlags, CloudABIWhence }; 59 60 #define ARG_MASK 0xff 61 #define OUT 0x100 62 #define IN /*0x20*/0 63 64 struct syscall_args { 65 enum Argtype type; 66 int offset; 67 }; 68 69 struct syscall { 70 STAILQ_ENTRY(syscall) entries; 71 const char *name; 72 u_int ret_type; /* 0, 1, or 2 return values */ 73 u_int nargs; /* actual number of meaningful arguments */ 74 /* Hopefully, no syscalls with > 10 args */ 75 struct syscall_args args[10]; 76 struct timespec time; /* Time spent for this call */ 77 int ncalls; /* Number of calls */ 78 int nerror; /* Number of calls that returned with error */ 79 bool unknown; /* Unknown system call */ 80 }; 81 82 struct syscall *get_syscall(struct threadinfo *, u_int, u_int); 83 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 84 85 /* 86 * Linux Socket defines 87 */ 88 #define LINUX_SOCKET 1 89 #define LINUX_BIND 2 90 #define LINUX_CONNECT 3 91 #define LINUX_LISTEN 4 92 #define LINUX_ACCEPT 5 93 #define LINUX_GETSOCKNAME 6 94 #define LINUX_GETPEERNAME 7 95 #define LINUX_SOCKETPAIR 8 96 #define LINUX_SEND 9 97 #define LINUX_RECV 10 98 #define LINUX_SENDTO 11 99 #define LINUX_RECVFROM 12 100 #define LINUX_SHUTDOWN 13 101 #define LINUX_SETSOCKOPT 14 102 #define LINUX_GETSOCKOPT 15 103 #define LINUX_SENDMSG 16 104 #define LINUX_RECVMSG 17 105 106 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 107 0 : sizeof(register_t) - sizeof(t)) 108 109 #if BYTE_ORDER == LITTLE_ENDIAN 110 #define PADL_(t) 0 111 #define PADR_(t) PAD_(t) 112 #else 113 #define PADL_(t) PAD_(t) 114 #define PADR_(t) 0 115 #endif 116 117 typedef int l_int; 118 typedef uint32_t l_ulong; 119 120 struct linux_socketcall_args { 121 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 122 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 123 }; 124 125 void init_syscalls(void); 126 void print_syscall(struct trussinfo *); 127 void print_syscall_ret(struct trussinfo *, int, long *); 128 void print_summary(struct trussinfo *trussinfo); 129
