Fenner - - CO-PILOT : Bill Roske - - DATE STARTED : 06/06/90 - - This module may be linked with c-modules requiring unexpected - signal handling. The parameters to tst_sig are as follows: - - fork_flag - set to FORK or NOFORK depending upon whether the - calling program executes a fork() system call. It - is normally the case that the calling program treats - SIGCLD as an expected signal if fork() is being used. - - handler - a pointer to the unexpected signal handler to - be executed after an unexpected signal has been - detected. If handler is set to DEF_HANDLER, a - default handler is used. This routine should be - declared as function returning an int. - - cleanup - a pointer to a cleanup routine to be executed - by the unexpected signal handler before tst_exit is - called. This parameter is set to NULL if no cleanup - routine is required. An external variable, T_cleanup - is set so that other user-defined handlers have - access to the cleanup routine. This routine should be - declared as returning type void. - -***************************************************************************/ - -#ifndef CRAY -#define _BSD_SIGNALS 1 /* Specify that we are using BSD signal interface */ -#endif - -#include <errno.h> -#include <string.h> -#include <signal.h> -#include "test.h" - -#define MAXMESG 150 /* size of mesg string sent to tst_res */ - -void (*T_cleanup)(); /* pointer to cleanup function */ - -extern int errno; -static void def_handler(); /* default signal handler */ - -/**************************************************************************** - * tst_sig() : set-up to catch unexpected signals. fork_flag is set to NOFORK - * if SIGCLD is to be an "unexpected signal", otherwise it is set to - * FORK. cleanup points to a cleanup routine to be executed before - * tst_exit is called (cleanup is set to NULL if no cleanup is desired). - * handler is a pointer to the signal handling routine (if handler is - * set to NULL, a default handler is used). - ***************************************************************************/ - -void -tst_sig(int fork_flag, void (*handler)(), void (*cleanup)()) -{ - char mesg[MAXMESG]; /* message buffer for tst_res */ - int sig; - - /* - * save T_cleanup and handler function pointers - */ - T_cleanup = cleanup; /* used by default handler */ - - if (handler == DEF_HANDLER) { - /* use default handler */ - handler = def_handler; - } - - /* - * now loop through all signals and set the handlers - */ - - for (sig = 1; sig < NSIG; sig++) { - /* - * SIGKILL is never unexpected. - * SIGCLD is only unexpected when - * no forking is being done. - * SIGINFO is used for file quotas and should be expected - */ - - switch (sig) { - case SIGKILL: - case SIGSTOP: - case SIGCONT: -#ifdef CRAY - case SIGINFO: - case SIGRECOVERY: /* allow chkpnt/restart */ -#endif /* CRAY */ - -#ifdef SIGSWAP - case SIGSWAP: -#endif /* SIGSWAP */ - -#ifdef SIGCKPT - case SIGCKPT: -#endif -#ifdef SIGRESTART - case SIGRESTART: -#endif - /* - * pthread-private signals SIGPTINTR and SIGPTRESCHED. - * Setting a handler for these signals is disallowed when - * the binary is linked against libpthread. - */ -#ifdef SIGPTINTR - case SIGPTINTR: -#endif /* SIGPTINTR */ -#ifdef SIGPTRESCHED - case SIGPTRESCHED: -#endif /* SIGPTRESCHED */ -#ifdef __CYGWIN__ - case SIGILL: - case SIGTRAP: - case SIGABRT: - case SIGEMT: - case SIGFPE: - case SIGBUS: -#endif - break; - - case SIGCLD: - if ( fork_flag == FORK ) - continue; - - default: - if (signal(sig, handler) == SIG_ERR) { - (void) sprintf(mesg, - "signal() failed for signal %d. error:%d %s.", - sig, errno, strerror(errno)); - tst_resm(TWARN, mesg); - } - break; - } -#ifdef __sgi - /* On irix (07/96), signal() fails when signo is 33 or higher */ - if ( sig+1 >= 33 ) - break; -#endif /* __sgi */ - - } /* endfor */ -} - - - -/**************************************************************************** - * def_handler() : default signal handler that is invoked when - * an unexpected signal is caught. - ***************************************************************************/ - -static void -def_handler(int sig) -{ - char mesg[MAXMESG]; /* holds tst_res message */ - - /* first reset trap for this signal (except SIGCLD - its weird) */ - if ((sig != SIGCLD) && (sig != SIGSTOP) && (sig != SIGCONT)) { - if (signal(sig, def_handler) == SIG_ERR) { - (void) sprintf(mesg, - "def_handler: signal() failed for signal %d. error:%d %s.", - sig, errno, strerror(errno)); - tst_resm(TWARN, mesg); - } - } - - (void) sprintf(mesg, "Unexpected signal %d received.", sig); - - /* - * Break remaining test cases, do any cleanup, then exit - */ - tst_brkm(TBROK, 0, mesg); - - /* now cleanup and exit */ - if (T_cleanup) { - (*T_cleanup)(); - } - - tst_exit(); -} |
