This number is either - * the number of bytes requested or smaller, if the EGD pool is - * drained and the daemon signals that the pool is empty. - * This routine does not touch any RAND_status(). This is necessary, since - * PRNG functions may call it during initialization. - * - * RAND_egd_bytes(path, bytes) will query "bytes" bytes and have them - * used to seed the PRNG. - * RAND_egd_bytes() is a wrapper for RAND_query_egd_bytes() with buf=NULL. - * Unlike RAND_query_egd_bytes(), RAND_status() is used to test the - * seed status so that the return value can reflect the seed state: - * -1 if an error occured during connection or communication _or_ - * if the PRNG has still not received the required seeding. - * num the number of bytes read from the EGD socket. This number is either - * the number of bytes requested or smaller, if the EGD pool is - * drained and the daemon signals that the pool is empty. - * - * RAND_egd(path) will query 255 bytes and use the bytes retreived to seed - * the PRNG. - * RAND_egd() is a wrapper for RAND_egd_bytes() with numbytes=255. - */ - -#if defined(OPENSSL_SYS_WIN32) || defined(OPENSSL_SYS_VMS) || defined(OPENSSL_SYS_MSDOS) || defined(OPENSSL_SYS_VXWORKS) || defined(OPENSSL_SYS_NETWARE) || defined(OPENSSL_SYS_VOS) || defined(OPENSSL_SYS_BEOS) -int RAND_query_egd_bytes(const char *path, unsigned char *buf, int bytes) - { - return(-1); - } -int RAND_egd(const char *path) - { - return(-1); - } - -int RAND_egd_bytes(const char *path,int bytes) - { - return(-1); - } -#else -#include <openssl/opensslconf.h> -#include OPENSSL_UNISTD -#include <sys/types.h> -#include <sys/socket.h> -#ifndef NO_SYS_UN_H -# ifdef OPENSSL_SYS_VXWORKS -# include <streams/un.h> -# else -# include <sys/un.h> -# endif -#else -struct sockaddr_un { - short sun_family; /* AF_UNIX */ - char sun_path[108]; /* path name (gag) */ -}; -#endif /* NO_SYS_UN_H */ -#include <string.h> -#include <errno.h> - -#ifndef offsetof -# define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER) -#endif - -int RAND_query_egd_bytes(const char *path, unsigned char *buf, int bytes) - { - int ret = 0; - struct sockaddr_un addr; - int len, num, numbytes; - int fd = -1; - int success; - unsigned char egdbuf[2], tempbuf[255], *retrievebuf; - - memset(&addr, 0, sizeof(addr)); - addr.sun_family = AF_UNIX; - if (strlen(path) >= sizeof(addr.sun_path)) - return (-1); - BUF_strlcpy(addr.sun_path,path,sizeof addr.sun_path); - len = offsetof(struct sockaddr_un, sun_path) + strlen(path); - fd = socket(AF_UNIX, SOCK_STREAM, 0); - if (fd == -1) return (-1); - success = 0; - while (!success) - { - if (connect(fd, (struct sockaddr *)&addr, len) == 0) - success = 1; - else - { - switch (errno) - { -#ifdef EINTR - case EINTR: -#endif -#ifdef EAGAIN - case EAGAIN: -#endif -#ifdef EINPROGRESS - case EINPROGRESS: -#endif -#ifdef EALREADY - case EALREADY: -#endif - /* No error, try again */ - break; -#ifdef EISCONN - case EISCONN: - success = 1; - break; -#endif - default: - goto err; /* failure */ - } - } - } - - while(bytes > 0) - { - egdbuf[0] = 1; - egdbuf[1] = bytes < 255 ? bytes : 255; - numbytes = 0; - while (numbytes != 2) - { - num = write(fd, egdbuf + numbytes, 2 - numbytes); - if (num >= 0) - numbytes += num; - else - { - switch (errno) - { -#ifdef EINTR - case EINTR: -#endif -#ifdef EAGAIN - case EAGAIN: -#endif - /* No error, try again */ - break; - default: - ret = -1; - goto err; /* failure */ - } - } - } - numbytes = 0; - while (numbytes != 1) - { - num = read(fd, egdbuf, 1); - if (num == 0) - goto err; /* descriptor closed */ - else if (num > 0) - numbytes += num; - else - { - switch (errno) - { -#ifdef EINTR - case EINTR: -#endif -#ifdef EAGAIN - case EAGAIN: -#endif - /* No error, try again */ - break; - default: - ret = -1; - goto err; /* failure */ - } - } - } - if(egdbuf[0] == 0) - goto err; - if (buf) - retrievebuf = buf + ret; - else - retrievebuf = tempbuf; - numbytes = 0; - while (numbytes != egdbuf[0]) - { - num = read(fd, retrievebuf + numbytes, egdbuf[0] - numbytes); - if (num == 0) - goto err; /* descriptor closed */ - else if (num > 0) - numbytes += num; - else - { - switch (errno) - { -#ifdef EINTR - case EINTR: -#endif -#ifdef EAGAIN - case EAGAIN: -#endif - /* No error, try again */ - break; - default: - ret = -1; - goto err; /* failure */ - } - } - } - ret += egdbuf[0]; - bytes -= egdbuf[0]; - if (!buf) - RAND_seed(tempbuf, egdbuf[0]); - } - err: - if (fd != -1) close(fd); - return(ret); - } - - -int RAND_egd_bytes(const char *path, int bytes) - { - int num, ret = 0; - - num = RAND_query_egd_bytes(path, NULL, bytes); - if (num < 1) goto err; - if (RAND_status() == 1) - ret = num; - err: - return(ret); - } - - -int RAND_egd(const char *path) - { - return (RAND_egd_bytes(path, 255)); - } - - -#endif |
