It extends the old 25 * epoll_create syscall by one parameter which is meant to hold a flag value. 26 * In this patch the only flag support is EPOLL_CLOEXEC which causes the 27 * close-on-exec flag for the returned file descriptor to be set. A new name 28 * EPOLL_CLOEXEC is introduced which in this implementation must have the same 29 * value as O_CLOEXEC. 30 */ 31 #include <errno.h> 32 #include <sys/epoll.h> 33 #include "tst_test.h" 34 #include "lapi/epoll.h" 35 #include "linux_syscall_numbers.h" 36 37 static void verify_epoll_create1(void) 38 { 39 int fd, coe; 40 41 fd = tst_syscall(__NR_epoll_create1, 0); 42 if (fd == -1) 43 tst_brk(TFAIL | TERRNO, "epoll_create1(0) failed"); 44 45 coe = SAFE_FCNTL(fd, F_GETFD); 46 if (coe & FD_CLOEXEC) 47 tst_brk(TFAIL, "flags=0 set close-on-exec flag"); 48 49 SAFE_CLOSE(fd); 50 51 fd = tst_syscall(__NR_epoll_create1, EPOLL_CLOEXEC); 52 if (fd == -1) 53 tst_brk(TFAIL | TERRNO, "epoll_create1(EPOLL_CLOEXEC) failed"); 54 55 coe = SAFE_FCNTL(fd, F_GETFD); 56 if ((coe & FD_CLOEXEC) == 0) 57 tst_brk(TFAIL, "flags=EPOLL_CLOEXEC didn't set close-on-exec"); 58 59 SAFE_CLOSE(fd); 60 61 tst_res(TPASS, "epoll_create1(EPOLL_CLOEXEC) PASSED"); 62 } 63 64 static struct tst_test test = { 65 .tid = "epoll_create1_01", 66 .min_kver = "2.6.27", 67 .test_all = verify_epoll_create1, 68 }; 69
