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 * Stat11 -- a pointer to a freebsd 11 stat buffer. Prints a couple fields. 14 * StatFs -- a pointer to a statfs buffer. Prints a few fields. 15 * Ioctl -- an ioctl command. Woefully limited. 16 * Quad -- a double-word value. e.g., lseek(int, offset_t, int) 17 * Signal -- a signal number. Prints the signal name (SIGxxx) 18 * Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port 19 * StringArray -- a pointer to an array of string pointers. 20 * Timespec -- a pointer to a struct timespec. Prints both elements. 21 * Timeval -- a pointer to a struct timeval. Prints both elements. 22 * Timeval2 -- a pointer to two struct timevals. Prints both elements of both. 23 * Itimerval -- a pointer to a struct itimerval. Prints all elements. 24 * Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events. 25 * Fd_set -- a pointer to an array of fd_set. Prints the fds that are set. 26 * Sigaction -- a pointer to a struct sigaction. Prints all elements. 27 * Sigset -- a pointer to a sigset_t. Prints the signals that are set. 28 * Sigprocmask -- the first argument to sigprocmask(). Prints the name. 29 * Kevent -- a pointer to an array of struct kevents. Prints all elements. 30 * Pathconf -- the 2nd argument of pathconf(). 31 * Utrace -- utrace(2) buffer. 32 * CapRights -- a pointer to a cap_rights_t. Prints all set capabilities. 33 * 34 * In addition, the pointer types (String, Ptr) may have OUT masked in -- 35 * this means that the data is set on *return* from the system call -- or 36 * IN (meaning that the data is passed *into* the system call). 37 */ 38 /* 39 * $FreeBSD$ 40 */ 41 42 enum Argtype { None = 1, Hex, Octal, Int, UInt, LongHex, Name, Ptr, Stat, Stat11, Ioctl, 43 Quad, Signal, Sockaddr, StringArray, Timespec, Timeval, Itimerval, 44 Pollfd, Fd_set, Sigaction, Fcntl, Mprot, Mmapflags, Whence, Readlinkres, 45 Sigset, Sigprocmask, StatFs, Kevent, Sockdomain, Socktype, Open, 46 Fcntlflag, Rusage, RusageWho, BinString, Shutdown, Resource, Rlimit, 47 Timeval2, Pathconf, Rforkflags, ExitStatus, Waitoptions, Idtype, Procctl, 48 LinuxSockArgs, Umtxop, Atfd, Atflags, Timespec2, Accessmode, Long, 49 Sysarch, ExecArgs, ExecEnv, PipeFds, QuadHex, Utrace, IntArray, Pipe2, 50 CapFcntlRights, Fadvice, FileFlags, Flockop, Getfsstatmode, Kldsymcmd, 51 Kldunloadflags, Sizet, Madvice, Socklent, Sockprotocol, Sockoptlevel, 52 Sockoptname, Msgflags, CapRights, PUInt, PQuadHex, Acltype, 53 Extattrnamespace, Minherit, Mlockall, Mountflags, Msync, Priowhich, 54 Ptraceop, Quotactlcmd, Reboothowto, Rtpriofunc, Schedpolicy, Schedparam, 55 56 CloudABIAdvice, CloudABIClockID, ClouduABIFDSFlags, 57 CloudABIFDStat, CloudABIFileStat, CloudABIFileType, 58 CloudABIFSFlags, CloudABILookup, CloudABIMFlags, CloudABIMProt, 59 CloudABIMSFlags, CloudABIOFlags, CloudABISDFlags, 60 CloudABISignal, CloudABISockStat, CloudABISSFlags, 61 CloudABITimestamp, CloudABIULFlags, CloudABIWhence }; 62 63 #define ARG_MASK 0xff 64 #define OUT 0x100 65 #define IN /*0x20*/0 66 67 struct syscall_args { 68 enum Argtype type; 69 int offset; 70 }; 71 72 struct syscall { 73 STAILQ_ENTRY(syscall) entries; 74 const char *name; 75 u_int ret_type; /* 0, 1, or 2 return values */ 76 u_int nargs; /* actual number of meaningful arguments */ 77 /* Hopefully, no syscalls with > 10 args */ 78 struct syscall_args args[10]; 79 struct timespec time; /* Time spent for this call */ 80 int ncalls; /* Number of calls */ 81 int nerror; /* Number of calls that returned with error */ 82 bool unknown; /* Unknown system call */ 83 }; 84 85 struct syscall *get_syscall(struct threadinfo *, u_int, u_int); 86 char *print_arg(struct syscall_args *, unsigned long*, long *, struct trussinfo *); 87 88 /* 89 * Linux Socket defines 90 */ 91 #define LINUX_SOCKET 1 92 #define LINUX_BIND 2 93 #define LINUX_CONNECT 3 94 #define LINUX_LISTEN 4 95 #define LINUX_ACCEPT 5 96 #define LINUX_GETSOCKNAME 6 97 #define LINUX_GETPEERNAME 7 98 #define LINUX_SOCKETPAIR 8 99 #define LINUX_SEND 9 100 #define LINUX_RECV 10 101 #define LINUX_SENDTO 11 102 #define LINUX_RECVFROM 12 103 #define LINUX_SHUTDOWN 13 104 #define LINUX_SETSOCKOPT 14 105 #define LINUX_GETSOCKOPT 15 106 #define LINUX_SENDMSG 16 107 #define LINUX_RECVMSG 17 108 109 #define PAD_(t) (sizeof(register_t) <= sizeof(t) ? \ 110 0 : sizeof(register_t) - sizeof(t)) 111 112 #if BYTE_ORDER == LITTLE_ENDIAN 113 #define PADL_(t) 0 114 #define PADR_(t) PAD_(t) 115 #else 116 #define PADL_(t) PAD_(t) 117 #define PADR_(t) 0 118 #endif 119 120 typedef int l_int; 121 typedef uint32_t l_ulong; 122 123 struct linux_socketcall_args { 124 char what_l_[PADL_(l_int)]; l_int what; char what_r_[PADR_(l_int)]; 125 char args_l_[PADL_(l_ulong)]; l_ulong args; char args_r_[PADR_(l_ulong)]; 126 }; 127 128 void init_syscalls(void); 129 void print_syscall(struct trussinfo *); 130 void print_syscall_ret(struct trussinfo *, int, long *); 131 void print_summary(struct trussinfo *trussinfo); 132
