In addition, many signal-related structures, such as + * sigset_ts, vary between Solaris and Linux. + * + * The simplest transformation that must be done when sending signals is to + * translate between Linux and Solaris signal numbers. + * + * These are the major signal number differences between Linux and Solaris: + * + * ==================================== + * | Number | Linux | Solaris | + * | ====== | ========= | ========== | + * | 7 | SIGBUS | SIGEMT | + * | 10 | SIGUSR1 | SIGBUS | + * | 12 | SIGUSR2 | SIGSYS | + * | 16 | SIGSTKFLT | SIGUSR1 | + * | 17 | SIGCHLD | SIGUSR2 | + * | 18 | SIGCONT | SIGCHLD | + * | 19 | SIGSTOP | SIGPWR | + * | 20 | SIGTSTP | SIGWINCH | + * | 21 | SIGTTIN | SIGURG | + * | 22 | SIGTTOU | SIGPOLL | + * | 23 | SIGURG | SIGSTOP | + * | 24 | SIGXCPU | SIGTSTP | + * | 25 | SIGXFSZ | SIGCONT | + * | 26 | SIGVTALARM | SIGTTIN | + * | 27 | SIGPROF | SIGTTOU | + * | 28 | SIGWINCH | SIGVTALARM | + * | 29 | SIGPOLL | SIGPROF | + * | 30 | SIGPWR | SIGXCPU | + * | 31 | SIGSYS | SIGXFSZ | + * ==================================== + * + * Not every Linux signal maps to a Solaris signal, nor does every Solaris + * signal map to a Linux counterpart. However, when signals do map, the + * mapping is unique. + * + * One mapping issue is that Linux supports 33 real time signals, with SIGRTMIN + * typically starting at or near 32 (SIGRTMIN) and proceeding to 64 (SIGRTMAX) + * (SIGRTMIN is "at or near" 32 because glibc usually "steals" one ore more of + * these signals for its own internal use, adjusting SIGRTMIN and SIGRTMAX as + * needed.) Conversely, Solaris actively uses signals 32-40 for other purposes + * and supports exactly 32 real time signals, in the range 41 (SIGRTMIN) + * to 72 (SIGRTMAX). + * + * At present, attempting to translate a Linux signal equal to 63 + * will generate an error (we allow SIGRTMAX because a program + * should be able to send SIGRTMAX without getting an EINVAL, though obviously + * anything that loops through the signals from SIGRTMIN to SIGRTMAX will + * fail.) + * + * Similarly, attempting to translate a native Solaris signal in the range + * 32-40 will also generate an error as we don't want to support the receipt of + * those signals from the Solaris global zone. + */ + +/* + * Linux to Solaris signal map + * + * Usage: solaris_signal = ltos_signum[lx_signal]; + */ +const int +ltos_signo[LX_NSIG + 1] = { + 0, + SIGHUP, + SIGINT, + SIGQUIT, + SIGILL, + SIGTRAP, + SIGABRT, + SIGBUS, + SIGFPE, + SIGKILL, + SIGUSR1, + SIGSEGV, + SIGUSR2, + SIGPIPE, + SIGALRM, + SIGTERM, + SIGEMT, /* 16: Linux SIGSTKFLT; use Solaris SIGEMT */ + SIGCHLD, + SIGCONT, + SIGSTOP, + SIGTSTP, + SIGTTIN, + SIGTTOU, + SIGURG, + SIGXCPU, + SIGXFSZ, + SIGVTALRM, + SIGPROF, + SIGWINCH, + SIGPOLL, + SIGPWR, + SIGSYS, + _SIGRTMIN, /* 32: Linux SIGRTMIN */ + _SIGRTMIN + 1, + _SIGRTMIN + 2, + _SIGRTMIN + 3, + _SIGRTMIN + 4, + _SIGRTMIN + 5, + _SIGRTMIN + 6, + _SIGRTMIN + 7, + _SIGRTMIN + 8, + _SIGRTMIN + 9, + _SIGRTMIN + 10, + _SIGRTMIN + 11, + _SIGRTMIN + 12, + _SIGRTMIN + 13, + _SIGRTMIN + 14, + _SIGRTMIN + 15, + _SIGRTMIN + 16, + _SIGRTMIN + 17, + _SIGRTMIN + 18, + _SIGRTMIN + 19, + _SIGRTMIN + 20, + _SIGRTMIN + 21, + _SIGRTMIN + 22, + _SIGRTMIN + 23, + _SIGRTMIN + 24, + _SIGRTMIN + 25, + _SIGRTMIN + 26, + _SIGRTMIN + 27, + _SIGRTMIN + 28, + _SIGRTMIN + 29, + _SIGRTMIN + 30, + _SIGRTMIN + 31, + _SIGRTMAX, /* 64: Linux SIGRTMAX */ +}; + +/* + * Solaris to Linux signal map + * + * Usage: lx_signal = stol_signo[solaris_signal]; + */ +const int +stol_signo[NSIG] = { + 0, + LX_SIGHUP, + LX_SIGINT, + LX_SIGQUIT, + LX_SIGILL, + LX_SIGTRAP, + LX_SIGABRT, + LX_SIGSTKFLT, /* 7: Solaris SIGEMT; use for LX_SIGSTKFLT */ + LX_SIGFPE, + LX_SIGKILL, + LX_SIGBUS, + LX_SIGSEGV, + LX_SIGSYS, + LX_SIGPIPE, + LX_SIGALRM, + LX_SIGTERM, + LX_SIGUSR1, + LX_SIGUSR2, + LX_SIGCHLD, + LX_SIGPWR, + LX_SIGWINCH, + LX_SIGURG, + LX_SIGPOLL, + LX_SIGSTOP, + LX_SIGTSTP, + LX_SIGCONT, + LX_SIGTTIN, + LX_SIGTTOU, + LX_SIGVTALRM, + LX_SIGPROF, + LX_SIGXCPU, + LX_SIGXFSZ, + -1, /* 32: Solaris SIGWAITING */ + -1, /* 33: Solaris SIGLWP */ + -1, /* 34: Solaris SIGFREEZE */ + -1, /* 35: Solaris SIGTHAW */ + -1, /* 36: Solaris SIGCANCEL */ + -1, /* 37: Solaris SIGLOST */ + -1, /* 38: Solaris SIGXRES */ + -1, /* 39: Solaris SIGJVM1 */ + -1, /* 40: Solaris SIGJVM2 */ + -1, /* 41: Solaris SIGINFO */ + LX_SIGRTMIN, /* 42: Solaris _SIGRTMIN */ + LX_SIGRTMIN + 1, + LX_SIGRTMIN + 2, + LX_SIGRTMIN + 3, + LX_SIGRTMIN + 4, + LX_SIGRTMIN + 5, + LX_SIGRTMIN + 6, + LX_SIGRTMIN + 7, + LX_SIGRTMIN + 8, + LX_SIGRTMIN + 9, + LX_SIGRTMIN + 10, + LX_SIGRTMIN + 11, + LX_SIGRTMIN + 12, + LX_SIGRTMIN + 13, + LX_SIGRTMIN + 14, + LX_SIGRTMIN + 15, + LX_SIGRTMIN + 16, + LX_SIGRTMIN + 17, + LX_SIGRTMIN + 18, + LX_SIGRTMIN + 19, + LX_SIGRTMIN + 20, + LX_SIGRTMIN + 21, + LX_SIGRTMIN + 22, + LX_SIGRTMIN + 23, + LX_SIGRTMIN + 24, + LX_SIGRTMIN + 25, + LX_SIGRTMIN + 26, + LX_SIGRTMIN + 27, + LX_SIGRTMIN + 28, + LX_SIGRTMIN + 29, + LX_SIGRTMIN + 30, + LX_SIGRTMIN + 31, + LX_SIGRTMAX, /* 74: Solaris _SIGRTMAX */ +}; + +/* + * Convert an illumos native signal number to a Linux signal number and return + * it.
