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 CapFcntlRights, Fadvice, FileFlags, Flockop, Getfsstatmode, Kldsymcmd, 49 Kldunloadflags, Sizet, Madvice, 50 51 CloudABIAdvice, CloudABIClockID, ClouduABIFDSFlags, 52 CloudABIFDStat, CloudABIFileStat, CloudABIFileType, 53 CloudABIFSFlags, CloudABILookup, CloudABIMFlags, CloudABIMProt, 54 CloudABIMSFlags, CloudABIOFlags, CloudABISDFlags, 55 CloudABISignal, CloudABISockStat, CloudABISSFlags, 56 CloudABITimestamp, CloudABIULFlags, CloudABIWhence }; 57 58 #define ARG_MASK 0xff 59 #define OUT 0x100 60 #define IN /*0x20*/0 61 62 struct syscall_args { 63 enum Argtype type; 64 int offset; 65 }; 66 67 struct syscall { 68 STAILQ_ENTRY(syscall) entries; 69 const char *name; 70 u_int ret_type; /* 0, 1, or 2 return values */ 71 u_int nargs; /* actual number of meaningful arguments */ 72 /* Hopefully, no syscalls with > 10 args */ 73 struct syscall_args args[10]; 74 struct timespec time; /* Time spent for this call */ 75 int ncalls; /* Number of calls */ 76 int nerror; /* Number of calls that returned with error */ 77 bool unknown; /* Unknown system call */ 78 }; 79 80 struct syscall *get_syscall(struct threadinfo *, u_int, u_int); 81 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 82 83 /* 84 * Linux Socket defines 85 */ 86 #define LINUX_SOCKET 1 87 #define LINUX_BIND 2 88 #define LINUX_CONNECT 3 89 #define LINUX_LISTEN 4 90 #define LINUX_ACCEPT 5 91 #define LINUX_GETSOCKNAME 6 92 #define LINUX_GETPEERNAME 7 93 #define LINUX_SOCKETPAIR 8 94 #define LINUX_SEND 9 95 #define LINUX_RECV 10 96 #define LINUX_SENDTO 11 97 #define LINUX_RECVFROM 12 98 #define LINUX_SHUTDOWN 13 99 #define LINUX_SETSOCKOPT 14 100 #define LINUX_GETSOCKOPT 15 101 #define LINUX_SENDMSG 16 102 #define LINUX_RECVMSG 17 103 104 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 105 0 : sizeof(register_t) - sizeof(t)) 106 107 #if BYTE_ORDER == LITTLE_ENDIAN 108 #define PADL_(t) 0 109 #define PADR_(t) PAD_(t) 110 #else 111 #define PADL_(t) PAD_(t) 112 #define PADR_(t) 0 113 #endif 114 115 typedef int l_int; 116 typedef uint32_t l_ulong; 117 118 struct linux_socketcall_args { 119 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 120 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 121 }; 122 123 void init_syscalls(void); 124 void print_syscall(struct trussinfo *); 125 void print_syscall_ret(struct trussinfo *, int, long *); 126 void print_summary(struct trussinfo *trussinfo); 127
