From 3a06f6a3cfad62da6dd8878d3446003f8293c3ae Mon Sep 17 00:00:00 2001 From: Greg Hudson Date: Sat, 29 Apr 2017 17:30:36 -0400 Subject: [PATCH] Add timestamp tests Add a test program for krb5int_validate_times() covering cases before and across the y2038 boundary. Add a GSSAPI test program to exercise lifetime queries, and tests using it in t_gssapi.py for ticket end times after y2038. Add a new test script t_y2038.py which only runs on platforms with 64-bit time_t to exercise end-user operations across and after y2038. Add an LDAP test case to test storage of post-y2038 timestamps. ticket: 8352 (cherry picked from commit 8ca62e54e89e2fbd6a089e8ab20b4e374a486003) [rharwood@redhat.com: prune gitignore] --- src/Makefile.in | 1 + src/config/pre.in | 2 + src/configure.in | 3 + src/lib/krb5/krb/Makefile.in | 14 ++-- src/lib/krb5/krb/t_valid_times.c | 109 ++++++++++++++++++++++++++++++ src/tests/Makefile.in | 1 + src/tests/gssapi/Makefile.in | 27 ++++---- src/tests/gssapi/t_gssapi.py | 32 +++++++++ src/tests/gssapi/t_lifetime.c | 140 +++++++++++++++++++++++++++++++++++++++ src/tests/t_kdb.py | 7 ++ src/tests/t_y2038.py | 75 +++++++++++++++++++++ 11 files changed, 395 insertions(+), 16 deletions(-) create mode 100644 src/lib/krb5/krb/t_valid_times.c create mode 100644 src/tests/gssapi/t_lifetime.c create mode 100644 src/tests/t_y2038.py diff --git a/src/Makefile.in b/src/Makefile.in index b0249778c..ad8565056 100644 --- a/src/Makefile.in +++ b/src/Makefile.in @@ -521,6 +521,7 @@ pyrunenv.vals: Makefile done > $@ echo "tls_impl = '$(TLS_IMPL)'" >> $@ echo "have_sasl = '$(HAVE_SASL)'" >> $@ + echo "sizeof_time_t = $(SIZEOF_TIME_T)" >> $@ runenv.py: pyrunenv.vals echo 'env = {}' > $@ diff --git a/src/config/pre.in b/src/config/pre.in index d961b5621..f23c07d9d 100644 --- a/src/config/pre.in +++ b/src/config/pre.in @@ -452,6 +452,8 @@ HAVE_SASL = @HAVE_SASL@ # Whether we have libresolv 1.1.5 for URI discovery tests HAVE_RESOLV_WRAPPER = @HAVE_RESOLV_WRAPPER@ +SIZEOF_TIME_T = @SIZEOF_TIME_T@ + # error table rules # ### /* these are invoked as $(...) foo.et, which works, but could be better */ diff --git a/src/configure.in b/src/configure.in index 24f653f0d..4ae2c07d5 100644 --- a/src/configure.in +++ b/src/configure.in @@ -744,6 +744,9 @@ fi AC_HEADER_TIME AC_CHECK_TYPE(time_t, long) +AC_CHECK_SIZEOF(time_t) +SIZEOF_TIME_T=$ac_cv_sizeof_time_t +AC_SUBST(SIZEOF_TIME_T) # Determine where to put the replay cache. diff --git a/src/lib/krb5/krb/Makefile.in b/src/lib/krb5/krb/Makefile.in index 0fe02a95d..55f82b147 100644 --- a/src/lib/krb5/krb/Makefile.in +++ b/src/lib/krb5/krb/Makefile.in @@ -364,6 +364,7 @@ SRCS= $(srcdir)/addr_comp.c \ $(srcdir)/t_in_ccache.c \ $(srcdir)/t_response_items.c \ $(srcdir)/t_sname_match.c \ + $(srcdir)/t_valid_times.c \ $(srcdir)/t_vfy_increds.c # Someday, when we have a "maintainer mode", do this right: @@ -457,9 +458,12 @@ t_response_items: t_response_items.o response_items.o $(KRB5_BASE_DEPLIBS) t_sname_match: t_sname_match.o sname_match.o $(KRB5_BASE_DEPLIBS) $(CC_LINK) -o $@ t_sname_match.o sname_match.o $(KRB5_BASE_LIBS) +t_valid_times: t_valid_times.o valid_times.o $(KRB5_BASE_DEPLIBS) + $(CC_LINK) -o $@ t_valid_times.o valid_times.o $(KRB5_BASE_LIBS) + TEST_PROGS= t_walk_rtree t_kerb t_ser t_deltat t_expand t_authdata t_pac \ - t_in_ccache t_cc_config t_copy_context \ - t_princ t_etypes t_vfy_increds t_response_items t_sname_match + t_in_ccache t_cc_config t_copy_context t_princ t_etypes t_vfy_increds \ + t_response_items t_sname_match t_valid_times check-unix: $(TEST_PROGS) $(RUN_TEST_LOCAL_CONF) ./t_kerb \ @@ -496,6 +500,7 @@ check-unix: $(TEST_PROGS) $(RUN_TEST) ./t_response_items $(RUN_TEST) ./t_copy_context $(RUN_TEST) ./t_sname_match + $(RUN_TEST) ./t_valid_times check-pytests: t_expire_warn t_vfy_increds $(RUNPYTEST) $(srcdir)/t_expire_warn.py $(PYTESTFLAGS) @@ -522,8 +527,9 @@ clean: $(OUTPRE)t_ad_fx_armor$(EXEEXT) $(OUTPRE)t_ad_fx_armor.$(OBJEXT) \ $(OUTPRE)t_vfy_increds$(EXEEXT) $(OUTPRE)t_vfy_increds.$(OBJEXT) \ $(OUTPRE)t_response_items$(EXEEXT) \ - $(OUTPRE)t_response_items.$(OBJEXT) $(OUTPRE)t_sname_match$(EXEEXT) \ - $(OUTPRE)t_sname_match.$(OBJEXT) \ + $(OUTPRE)t_response_items.$(OBJEXT) \ + $(OUTPRE)t_sname_match$(EXEEXT) $(OUTPRE)t_sname_match.$(OBJEXT) \ + $(OUTPRE)t_valid_times$(EXEEXT) $(OUTPRE)t_valid_times.$(OBJECT) \ $(OUTPRE)t_parse_host_string$(EXEEXT) \ $(OUTPRE)t_parse_host_string.$(OBJEXT) diff --git a/src/lib/krb5/krb/t_valid_times.c b/src/lib/krb5/krb/t_valid_times.c new file mode 100644 index 000000000..1b469ffc2 --- /dev/null +++ b/src/lib/krb5/krb/t_valid_times.c @@ -0,0 +1,109 @@ +/* -*- mode: c;
