From 8864cde3495dbfd6b476c1b77a8bde035e1cf000 Mon Sep 17 00:00:00 2001 From: ngie Date: Fri, 10 Feb 2017 01:13:12 +0000 Subject: MFC r305358,r305449,r305451,r306367,r306397,r309474: This also contains a merge of ^/projects/netbsd-tests-update-12@r304035 . This change never hit ^/head because bin/cat's behavior was changed (on ^/head) to match NetBSD. PR: 210607 r305358: Update contrib/netbsd-tests with new content from NetBSD This updates the snapshot from 09/30/2014 to 08/11/2016 This brings in a number of new testcases from upstream, most notably: - bin/cat - lib/libc - lib/msun - lib/libthr - usr.bin/sort lib/libc/tests/stdio/open_memstream_test.c was moved to lib/libc/tests/stdio/open_memstream2_test.c to accomodate the new open_memstream test from NetBSD. Tested on: amd64 (VMware fusion VM; various bare metal platforms); i386 (VMware fusion VM); make tinderbox r305449: Install h_db to unbreak some of the lib/libc/db testcases after r305358 r305451: Fix lib/libc/rpc test assumptions added in r305358 - Require root in the tcp/udp subtests (it's needed on FreeBSD when registering services). - Skip the tests if service registration fails. r306367 (by br): Allow up to 6 arguments only on MIPS. r306397 (by br): Use right piece of code for FreeBSD. r309474: Don't build :strvis_locale if VIS_NOLOCALE is undefined The copy of contrib/libc-vis on ^/stable/10 doesn't contain all of the features in the ^/stable/11 // ^/head version, including VIS_NOLOCALE. The risk is lower in conditionally running the test instead of backporting the newer version of libc-vis --- contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c | 155 ++++++++++++++++++++++++- 1 file changed, 150 insertions(+), 5 deletions(-) (limited to 'contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c') diff --git a/contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c b/contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c index 6686f02..e911d42 100644 --- a/contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c +++ b/contrib/netbsd-tests/lib/libc/sys/t_sigqueue.c @@ -1,4 +1,4 @@ -/* $NetBSD: t_sigqueue.c,v 1.4 2011/07/07 16:31:11 jruoho Exp $ */ +/* $NetBSD: t_sigqueue.c,v 1.6 2016/08/04 06:43:43 christos Exp $ */ /*- * Copyright (c) 2011 The NetBSD Foundation, Inc. @@ -30,8 +30,7 @@ */ #include -__RCSID("$NetBSD: t_sigqueue.c,v 1.4 2011/07/07 16:31:11 jruoho Exp $"); - +__RCSID("$NetBSD: t_sigqueue.c,v 1.6 2016/08/04 06:43:43 christos Exp $"); #include #include @@ -40,6 +39,11 @@ __RCSID("$NetBSD: t_sigqueue.c,v 1.4 2011/07/07 16:31:11 jruoho Exp $"); #include #include +#ifdef __FreeBSD__ +#include +#include +#endif + static void handler(int, siginfo_t *, void *); #define VALUE (int)0xc001dad1 @@ -77,7 +81,7 @@ ATF_TC_BODY(sigqueue_basic, tc) sv.sival_int = VALUE; #ifdef __FreeBSD__ - /* + /* * From kern_sig.c: * Specification says sigqueue can only send signal to single process. */ @@ -99,17 +103,158 @@ ATF_TC_HEAD(sigqueue_err, tc) ATF_TC_BODY(sigqueue_err, tc) { - union sigval sv; + static union sigval sv; errno = 0; ATF_REQUIRE_ERRNO(EINVAL, sigqueue(getpid(), -1, sv) == -1); } +static int signals[] = { + SIGINT, SIGRTMIN + 1, SIGINT, SIGRTMIN + 0, SIGRTMIN + 2, + SIGQUIT, SIGRTMIN + 1 +}; +#ifdef __arraycount +#define CNT __arraycount(signals) +#else +#define CNT (sizeof(signals) / sizeof(signals[0])) +#endif + +static sig_atomic_t count = 0; +static int delivered[CNT]; + +static void +myhandler(int signo, siginfo_t *info, void *context) +{ + delivered[count++] = signo; +#ifdef __FreeBSD__ + printf("Signal #%zu: signo: %d\n", (size_t)count, signo); +#endif +} + +static int +asc(const void *a, const void *b) +{ + const int *ia = a, *ib = b; + return *ib - *ia; +} + +/* + * given a array of signals to be delivered in tosend of size len + * place in ordered the signals to be delivered in delivery order + * and return the number of signals that should be delivered + */ +static size_t +sigorder(int *ordered, const int *tosend, size_t len) +{ + memcpy(ordered, tosend, len * sizeof(*tosend)); + qsort(ordered, len, sizeof(*ordered), asc); + if (len == 1) + return len; + +#ifdef __FreeBSD__ + /* + * Don't dedupe signal numbers (bug 212173) + * + * Per kib's comment.. + * + * " + * OTOH, FreeBSD behaviour is to treat all signals as realtime while + * there is no mem shortage and siginfo can be allocated.
