2018-12-14Add missing libnss_testX.so requirement for tst-nss-test3.Stefan Liebler
Sometimes tst-nss-test3 fails with: error: test-container.c:386: unable to open .../nss/libnss_test1.so for reading The test tst-nss-test3 which runs in a container needs libnss_test[12].so. (see e.g. tst-nss-test3.script). Before this test was moved from tests to tests-container variable, the requirement was met. Thus this patch adds this requirement also for tests in tests-container. ChangeLog: * nss/Makefile (tst-nss-test3.out): New rule.
2018-10-09Increase timeout of nss/tst-nss-files-hosts-multiSzabolcs Nagy
Increase timeout from the default 20s to 40s. This test makes close to 2 million syscalls with distribution: 1180249 connect 297952 getsockname 144040 lseek 143734 read 14466 close ... connect can be slow, so the default timeout was not enough on slow systems.

2018-08-14nss_files: Fix file stream leak in aliases lookup [BZ #23521]Florian Weimer
In order to get a clean test case, it was necessary to fix partially fixed bug 23522 as well.

2018-07-06nss_files: Fix re-reading of long lines [BZ #18991]Florian Weimer
Use the new __libc_readline_unlocked function to pick up reading at the same line in case the buffer needs to be enlarged.

2018-06-25getgrent_next_nss (compat-initgroups): Remove alloca fallback [BZ #18023]Florian Weimer
If the caller-supplied buffer is not large enough, fall back directly malloc. The previous __libc_use_alloca check was incorrect because it did not take into account that extend_alloca may fail to merge allocations, so it would underestimate the stack space being used by roughly a factor of two.

2018-02-15Fix -Os feof_unlocked linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers
Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for feof_unlocked. The usual approach is followed of adding __feof_unlocked (inlined when feof_unlocked is), making calls use it when required for namespace reasons, and using libc_hidden_proto / libc_hidden_weak for the feof_unlocked weak alias when only localplt but not namespace issues are involved. In the case of getaddrinfo.c, use of __feof_unlocked needs to be conditional since that code is also used in nscd (where __feof_unlocked is not available). Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.

2017-08-14NSS: Replace exported NSS lookup functions with stubs [BZ #21962]Florian Weimer
Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to nss/XXX-lookup.c: +#ifndef NO_COMPAT +int +internal_function attribute_compat_text_section +DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp) +{ + return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp); +} +#endif That is, it adds a pseudo-compat function with an internal_function attribute. The function it was supposed to replace did not have the attribute: extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name, - void **fctp) internal_function; + const char *fct2_name, void **fctp) + internal_function; This changed the calling convention on i386 for the following functions in the public ABI: __nss_passwd_lookup __nss_group_lookup __nss_hosts_lookup This commit replaces the functions with always-failing stubs, with true compat symbols. Due to a happy accident, the calling convention of the stub is identical for the internal_function and non-internal_function case on i386. In addition, this commit auto-generates the __nss_*_lookup2 function declarations as part of <nsswitch.h>.

2017-08-07Consistently use uintN_t not u_intN_t everywhere.Joseph Myers
This patch changes the remaining uses of the old nonstandard u_intN_t types in glibc to use the C99 uintN_t instead, except for the definitions of those typedefs and the tests of them in the c++-types test. This follows the previous such fix for libm, and being consistent in using uintN_t makes sense as a global cleanup.

2017-07-03resolv: Introduce struct resolv_context [BZ #21668]Florian Weimer
struct resolv_context objects provide a temporary resolver context which does not change during a name lookup operation. Only when the outmost context is created, the stub resolver configuration is verified to be current (at present, only against previous res_init calls). Subsequent attempts to obtain the context will reuse the result of the initial verification operation. struct resolv_context can also be extended in the future to store data which needs to be deallocated during thread cancellation.
2017-06-27resolv: Call _res_hconf_init from __res_vinitFlorian Weimer
Many callers of __res_maybe_init also call _res_hconf_init. Additional calls to the latter do not hurt because the function does its work only once. (/etc/hosts.conf is not reloaded or even checked for changes.) This means that we can simplify the code by calling _res_hconf_init directly from __res_vinit.
2017-05-11Suppress internal declarations for most of the testsuite.Zack Weinberg
This patch adds a new build module called 'testsuite'. IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus (which means several ad-hoc tests for __cplusplus can go away). libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is defined; in particular, _ISOMAC mode does not get config.h automatically anymore. There are still quite a few tests that need to see internal gunk of one variety or another. For them, we now have 'tests-internal' and 'test-internal-extras'; files in this category will still be compiled with MODULE_NAME=nonlib, and everything proceeds as it always has. The bulk of this patch is moving tests from 'tests' to 'tests-internal'. There is also 'tests-static-internal', which has the same effect on files in 'tests-static', and 'modules-names-tests', which has the *inverse* effect on files in 'modules-names' (it's inverted because most of the things in modules-names are *not* tests). For both of these, the file must appear in *both* the new variable and the old one. There is also now a special case for when libc-symbols.h is included without MODULE_NAME being defined at all. (This happens during the creation of libc-modules.h, and also when preprocessing Versions files.) When this happens, IS_IN is set to be always false and _ISOMAC is *not* defined, which was the status quo, but now it's explicit. The remaining changes to C source files in this patch seemed likely to cause problems in the absence of the main change. They should be relatively self-explanatory. In a few cases I duplicated a definition from an internal header rather than move the test to tests-internal; this was a judgement call each time and I'm happy to change those however reviewers feel is more appropriate. * Makerules: New subdir configuration variables 'tests-internal' and 'test-internal-extras'. Test files in these categories will still be compiled with MODULE_NAME=nonlib. Test files in the existing categories (tests, xtests, test-srcs, test-extras) are now compiled with MODULE_NAME=testsuite. New subdir configuration variable 'modules-names-tests'. Files which are in both 'modules-names' and 'modules-names-tests' will be compiled with MODULE_NAME=testsuite instead of MODULE_NAME=extramodules. (gen-as-const-headers): Move to tests-internal. (do-tests-clean, common-mostlyclean): Support tests-internal. * Makeconfig (built-modules): Add testsuite. * Makefile: Change libof-check-installed-headers-c and libof-check-installed-headers-cxx to 'testsuite'. * Rules: Likewise. Support tests-internal. * benchtests/strcoll-inputs/filelist#en_US.UTF-8: Remove extra-modules.mk. * config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here. * include/libc-symbols.h: Move definitions of _GNU_SOURCE, PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the very top of the file and rationalize their order. If MODULE_NAME is not defined at all, define IS_IN to always be false, and don't define _ISOMAC. If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are true, define _ISOMAC and suppress everything else in this file, starting with the inclusion of config.h. Do check for inappropriate definitions of __OPTIMIZE__ and __FAST_MATH__ here, but only if _ISOMAC is not defined. Correct some out-of-date commentary. * include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE and _Mlong_double_ before including math.h. * include/string.h: If _ISOMAC is defined, don't expose _STRING_ARCH_unaligned. Move a comment to a more appropriate location. * include/errno.h, include/stdio.h, include/stdlib.h, include/string.h * include/time.h, include/unistd.h, include/wchar.h: No need to check __cplusplus nor use __BEGIN_DECLS/__END_DECLS. * misc/sys/cdefs.h (__NTHNL): New macro. * sysdeps/m68k/m680x0/fpu/bits/mathinline.h (__m81_defun): Use __NTHNL to avoid errors with GCC 6. * elf/tst-env-setuid-tunables.c: Include config.h with _LIBC defined, for HAVE_TUNABLES. * inet/tst-checks-posix.c: No need to define _ISOMAC. * intl/tst-gettext2.c: Provide own definition of N_. * math/test-signgam-finite-c99.c: No need to define _ISOMAC. * math/test-signgam-main.c: No need to define _ISOMAC. * stdlib/tst-strtod.c: Convert to test-driver.

2017-03-01Miscellaneous low-risk changes preparing for _ISOMAC testsuite.Zack Weinberg
These are a grab bag of changes where the testsuite was using internal symbols of some variety, but this was straightforward to fix, and the fixed code should work with or without the change to compile the testsuite under _ISOMAC. Four of these are just more #include adjustments, but I want to highlight sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been written before the advent of sys/auxv.h. I think a big chunk of this file could be replaced by a simple call to getauxval, but I'll let someone who actually has a powerpc machine to test on do that. dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos, I have removed this. math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal configuration macro, to decide whether to do certain tests involving 'long double'. I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG instead, which uses only public float.h macros and is equivalent on all supported platforms. (Note that NO_LONG_DOUBLE doesn't mean 'the compiler doesn't support long double', it means 'long double is the same as double'.) tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile was using the internal __getpagesize in the definition; changed to sysconf(_SC_PAGESIZE) which is the POSIX equivalent. ia64-linux doesn't supply 'clone', only '__clone2', which is not defined in the public headers(!) All the other clone tests have local extern declarations of __clone2, but tst-clone.c doesn't; it was getting away with this because include/sched.h does declare __clone2. * nss/tst-cancel-getpwuid_r.c: Include nss.h. * string/strcasestr.c: No need to include config.h. * sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include sys/auxv.h. Don't include sysdep.h. * sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h. * dlfcn/tst-dladdr.c: Don't include ldsodefs.h. Don't use DL_LOOKUP_ADDRESS. * math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether LDBL_MANT_DIG is greater than DBL_MANT_DIG. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use sysconf (_SC_PAGESIZE) instead of __getpagesize in definition of ARTIFICIAL_LIMIT. * sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern declaration of __clone2.
2017-01-05Increase some test timeouts.Joseph Myers
This patch increases timeouts on some tests I've observed timing out. elf/tst-tls13 and iconvdata/tst-loading both dynamically load many objects and so are slow when testing over NFS. They had timeouts set from before the default changed from 2 to 20 seconds; this patch removes those old settings, so effectively increasing the timeout to 20 seconds (from 3 and 10 seconds respectively). malloc/tst-malloc-thread-fail.c and malloc/tst-mallocfork2.c are slow on slow systems and so I set a fairly arbitrary 100 second timeout, which seems to suffice on the system where I saw them timing out. nss/tst-cancel-getpwuid_r.c and nss/tst-nss-getpwent.c are slow on systems with a large passwd file; I set timeouts that empirically worked for me. (It seems tst-cancel-getpwuid_r.c is hitting the 100000 getpwuid_r call limit in my testing, with each call taking a bit over 0.007 seconds, so 700 seconds for the test.) * elf/tst-tls13.c (TIMEOUT): Remove. * iconvdata/tst-loading.c (TIMEOUT): Likewise. * malloc/tst-malloc-thread-fail.c (TIMEOUT): Increase to 100. * malloc/tst-mallocfork2.c (TIMEOUT): Define to 100. * nss/tst-cancel-getpwuid_r.c (TIMEOUT): Define to 900. * nss/tst-nss-getpwent.c (TIMEOUT): Define to 300.

2016-12-23Add deferred cancellation regression test for getpwuid_r.Carlos O'Donell
The fix in commit 312be3f9f5eab1643d7dcc7728c76d413d4f2640 resolved several cancellation issues in several APIs. This regression test is designed to double check that at least getpwuid_r remainds correctly implemented and does not provide additional unintended cancellation points that may leave locks in an inconsistent state.
2016-08-18Fix incorrect double-checked locking related to _res_hconf.initialized.Torvald Riegel
_res_hconf.initialized was not suitable for use in a multi-threaded environment due to the lack of atomics and memory barriers. Use of it was also unnecessary because _res_hconf_init did the right thing by using __libc_once. This patch fixes the glibc-internal uses by just calling _res_hconf_init unconditionally, and switches to a release MO atomic store for _res_hconf.initialized to fix the glibc side of the synchronization problem (which will maintain backward compatibility, but cannot fix the lack of acquire MO on any glibc-external loads). [BZ #20477] * resolv/res_hconf.c (do_init): Use atomic access. * resolv/res_hconf.h: Add comments. * nscd/aicache.c (addhstaiX): Call _res_hconf_init unconditionally. * nss/getXXbyYY_r.c (REENTRANT_NAME): Likewise. * sysdeps/posix/getaddrinfo.c (gaih_inet): Likewise.
2016-06-11nss_db: Fix initialization of iteration position [BZ #20237]Florian Weimer
When get*ent is called without a preceding set*ent, we need to set the initial iteration position in get*ent. Reproducer: Add “services: db files” to /etc/nsswitch.conf, then run “perl -e getservent”. It will segfault before this change, and exit silently after it.
