* Fix linknamespace expectations for in6addr_any, in6addr_loopback.Joseph Myers2015-06-141-3/+4
| | | | | | | | | | | | | | | | | | | | Some linknamespace test failures turned out to be because the variables in6addr_any and in6addr_loopback weren't listed in the lists of extra reserved symbols for the relevant standards (only functions are handled automatically through -aux-info, data symbols need listing manually in list-header-symbols.pl). This patch duly adds those symbols to those lists (there are still failures for older standards because of references to those symbols being brought in for standards that didn't reserve them: bug 18532, to be fixed separately). Tested for x86_64. * conform/list-header-symbols.pl (%extra_syms): Add in6addr_any and in6addr_loopback for XOPEN2K, XOPEN2K8 and POSIX2008. * conform/Makefile (test-xfail-XOPEN2K/netdb.h/linknamespace): Remove variable.

* Fix linknamespace h_errno handling.Joseph Myers2014-12-041-3/+4
| | | | | | | | | | | | | | | | | | | | Some linknamespace tests were failing because of references to h_errno. References to this symbol should be allowed for XPG4, UNIX98 and XOPEN2K; this patch adds it to the list of allowed data symbols for those standards. (h_errno was removed in the 2008 edition of POSIX, so POSIX2008 and XOPEN2K8 references to it are genuine bugs; fortunately it's not a public data symbol - __h_errno_location is public, TLS h_errno is GLIBC_PRIVATE - so the symbol can simply be renamed to __h_errno to fix those bugs without the ABI complications normally associated with namespace issues for data symbols.) Tested for x86_64. * conform/list-header-symbols.pl (%extra_syms): Add h_errno for XPG4, UNIX98 and XOPEN2K. * conform/Makefile (test-xfail-XOPEN2K/grp.h/linknamespace): Remove variable.

* Fix linknamespace getdate_err handling.Joseph Myers2014-12-031-4/+4
| | | | | | | | | | | | | | | | | Some linknamespace tests were failing because of references to getdate_err. References to this symbol should be allowed for XPG4 and later XSI standards; it was missing from the whitelist of data symbols. This patch adds it to that list. Tested for x86_64. * conform/list-header-symbols.pl (%extra_syms): Add getdate_err for XPG4, UNIX98, XOPEN2K and XOPEN2K8. * conform/Makefile (test-xfail-XOPEN2K/pthread.h/linknamespace): Remove variable.

* Add tests for namespace for static linking.Joseph Myers2014-11-121-0/+81
One thing we currently try to ensure manually is that glibc is namespace-clean for static linking; that is, if you only use features from a particular standard (including the set of features exposed by headers given feature test macros such as _DEFAULT_SOURCE that don't correspond to any written standard), the library objects brought in by the static linker will not define or use (strong) names that are reserved to the user in that standard. This patch implements automatic tests for this, using the same set of standards as for the header conformance tests (it would, however, be easy to add more standards for this testing, without them needing to have the definitions of expected header contents for the header tests). The tests are based on the functions declared in each header, as extracted using GCC's -aux-info option. The following comment from linknamespace.pl explains the caveats around this approach: Here's an example of the output for ISO (C90) assert.h, from before my recent fixes and whitelisting of cases that seem more complicated to fix: [initial] __assert_fail -> [libc.a(assert.o)] free -> [libc.a(malloc.o)] __get_nprocs -> [libc.a(getsysstats.o)] fgets_unlocked [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __libc_setlocale_lock -> [libc.a(setlocale.o)] _nl_archive_subfreeres -> [libc.a(loadarchive.o)] __sysconf -> [libc.a(sysconf.o)] __tzname_max -> [libc.a(tzset.o)] __tzfile_compute -> [libc.a(tzfile.o)] fileno [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __libc_setlocale_lock -> [libc.a(setlocale.o)] _nl_archive_subfreeres -> [libc.a(loadarchive.o)] __sysconf -> [libc.a(sysconf.o)] __tzname_max -> [libc.a(tzset.o)] __tzfile_compute -> [libc.a(tzfile.o)] fread_unlocked [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __libc_setlocale_lock -> [libc.a(setlocale.o)] _nl_archive_subfreeres -> [libc.a(loadarchive.o)] __sysconf -> [libc.a(sysconf.o)] __tzname_max -> [libc.a(tzset.o)] __tzfile_compute -> [libc.a(tzfile.o)] ftello [initial] __assert_fail -> [libc.a(assert.o)] free -> [libc.a(malloc.o)] malloc_info [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __libc_setlocale_lock -> [libc.a(setlocale.o)] _nl_default_locale_path -> [libc.a(findlocale.o)] memmem [initial] __assert_perror_fail -> [libc.a(assert-perr.o)] __strerror_r -> [libc.a(_strerror.o)] mempcpy [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] _nl_find_domain -> [libc.a(finddomain.o)] _nl_expand_alias -> [libc.a(localealias.o)] qsort -> [libc.a(msort.o)] qsort_r [initial] __assert_fail -> [libc.a(assert.o)] _dl_pagesize -> [libc.a(dl-support.o)] __rawmemchr -> [libc.a(rawmemchr.o)] rawmemchr [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __getcwd -> [libc.a(getcwd.o)] rewinddir [initial] __assert_fail -> [libc.a(assert.o)] stderr [initial] __assert_fail -> [libc.a(assert.o)] stderr -> [libc.a(stdio.o)] stdin [initial] __assert_fail -> [libc.a(assert.o)] stderr -> [libc.a(stdio.o)] stdout [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] stpcpy [initial] __assert_fail -> [libc.a(assert.o)] __fxprintf -> [libc.a(fxprintf.o)] _IO_vfprintf -> [libc.a(vfprintf.o)] __printf_fp -> [libc.a(printf_fp.o)] wmemset Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h failures; I think the remaining 154 mostly represent genuine bugs in glibc that should mostly be straightforward to fix (probably rather fewer than 154 bugs - issues generally affect multiple headers, for multiple standards). (When fixing, of course you need to file a bug in Bugzilla, and check for the possibility that the header conditionals are what's incorrect - that the first listed symbol shouldn't have been declared, or that the symbol finally brought in should have been declared.) * conform/GlibcConform.pm: New file. * conform/conformtest.pl: Use GlibcConform module. * conform/linknamespace.pl: New file. * conform/list-header-symbols.pl: Likewise. * conform/Makefile (linknamespace-symlists-base): New variable.
