If the process +# holding the current lock on the file then tries to call exec() on the file +# it has locked, it can fail with ETXTBUSY even though the advisory lock is +# preventing other threads from successfully completing a writable open(). +# +# The second change closes a race where a read-only open() with O_SHLOCK or +# O_EXLOCK may return successfully while the write count is non-zero due to +# another descriptor that had the advisory lock and was blocking the open() +# still being in the process of closing. If the process that completed the +# open() then attempts to call exec() on the file it locked, it can fail with +# ETXTBUSY even though the other process that held a write lock has closed +# the file and released the lock. + +# https://people.freebsd.org/~pho/stress/log/kostik859.txt +# https://people.freebsd.org/~pho/stress/log/kostik860.txt + +# Fixed by r294204. + +. ../default.cfg + +[ `id -u ` -ne 0 ] && echo "Must be root!" && exit 1 + +dir=/tmp +odir=`pwd` +cd $dir +sed '1,/^EOF/d' < $odir/$0 > $dir/advlock.c +mycc -o advlock -Wall -Wextra -O0 -g advlock.c || exit 1 +rm -f advlock.c + +mount | grep "on $mntpoint " | grep -q /dev/md && umount -f $mntpoint +mdconfig -l | grep -q md$mdstart && mdconfig -d -u $mdstart +mdconfig -a -t swap -s 512m -u $mdstart || exit 1 +bsdlabel -w md$mdstart auto +newfs $newfs_flags md${mdstart}$part > /dev/null +mount /dev/md${mdstart}$part $mntpoint + +cp /usr/bin/true $mntpoint +cd $mntpoint +/tmp/advlock +r=$? +cd $odir + +while mount | grep "on $mntpoint " | grep -q /dev/md; do + umount $mntpoint || sleep 1 +done +mdconfig -d -u $mdstart +rm -f /tmp/advlock +exit $r + +EOF +#include +#include +#include +#include + +#include + +#include +#include +#include +#include +#include +#include +#include +#include + +volatile u_int *share; +char *cmdline[] = { "./true", NULL }; +const char *tp; + +#define SYNC 0 +#define PARALLEL 2 + +#define RUNTIME (1 * 60) + +void +handler(int i __unused) { + + fprintf(stderr, "ALARM from %s.\n", tp); + _exit(1); +} + +void +slock(void) +{ + int fd; + + setproctitle("%s", __func__); + atomic_add_int(&share[SYNC], 1); + while (share[SYNC] != PARALLEL) + ; + + tp = __func__; + alarm(2); + if ((fd = open(cmdline[0], O_RDONLY | O_SHLOCK)) == -1) + err(1, "open(%s). %d", cmdline[0], __LINE__); + usleep(500); + close(fd); + + _exit(0); +} + +void +elock(void) +{ + int fd; + + setproctitle("%s", __func__); + atomic_add_int(&share[SYNC], 1); + while (share[SYNC] != PARALLEL) + ; + + tp = __func__; + alarm(2); + if ((fd = open(cmdline[0], O_WRONLY | O_EXLOCK)) == -1) { + if (errno != ETXTBSY) + err(1, "open(%s). %d", cmdline[0], __LINE__); + } else { + usleep(500); + close(fd); + } + + _exit(0); +} + +void +stest(void) +{ + int fd; + + setproctitle("%s", __func__); + atomic_add_int(&share[SYNC], 1); + while (share[SYNC] != PARALLEL) + ; + + tp = __func__; + alarm(2); + if ((fd = open(cmdline[0], O_RDONLY | O_SHLOCK)) == -1) + err(1, "open(%s). %d", cmdline[0], __LINE__); + + if (execve(cmdline[0], cmdline, NULL) == -1) + err(1, "execve(%s) @ %d", cmdline[0], __LINE__); + + _exit(0); +} + +void +etest(void) +{ + int fd; + + setproctitle("%s", __func__); + atomic_add_int(&share[SYNC], 1); + while (share[SYNC] != PARALLEL) + ; + + tp = __func__; + alarm(2); + if ((fd = open(cmdline[0], O_RDONLY | O_EXLOCK)) == -1) + err(1, "open(%s). %d", cmdline[0], __LINE__); + + if (execve(cmdline[0], cmdline, NULL) == -1) + err(1, "execve(%s) @ %d", cmdline[0], __LINE__); + + _exit(0); +} + +int +main(void) +{ + size_t len; + time_t start; + int i, n, r, s; + + len = PAGE_SIZE; + if ((share = mmap(NULL, len, PROT_READ | PROT_WRITE, MAP_ANON | MAP_SHARED, + -1, 0)) == MAP_FAILED) + err(1, "mmap"); + + signal(SIGALRM, handler); + n = r = 0; + start = time(NULL); + while ((time(NULL) - start) < RUNTIME) { + n++; + share[SYNC] = 0; + if (fork() == 0) + slock(); + if (fork() == 0) + stest(); + + for (i = 0; i < PARALLEL; i++) { + wait(&s); + r += s == 0 ? 0 : 1; + } + if (r != 0) + break; + + share[SYNC] = 0; + if (fork() == 0) + elock(); + if (fork() == 0) + etest(); + + for (i = 0; i < PARALLEL; i++) { + wait(&s); + r += s == 0 ? 0 : 1; + } + if (r != 0) + break; + } + if (r != 0) + fprintf(stderr, "FAIL @ %d\n", n); + + return (r); +} diff --git a/tools/test/stress2/misc/aesni.sh b/tools/test/stress2/misc/aesni.sh new file mode 100755 index 000000000000..c25694fa002a --- /dev/null +++ b/tools/test/stress2/misc/aesni.sh @@ -0,0 +1,38 @@ +#!/bin/sh + +# +# SPDX-License-Identifier: BSD-2-Clause-FreeBSD +# +# Copyright (c) 2018 Dell EMC Isilon +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# 1.
