* Fix profil_counter namespace (bug 17725).Joseph Myers2014-12-1716-21/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM, where profil_counter is not static, it is brought in by references to various standard functions, as noted in <https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although it is not a standard function itself. I don't know if this also causes test failures on SPARC, although I see no reason for it not to do so. This patch fixes this namespace issue. profil_counter is renamed to __profil_counter and made a weak alias on ARM and SPARC. Because of the uses in profil.c / sprofil.c it seems simplest to make the rename globally, including on the other architectures for which profil_counter was static and so the change is of no substance. The variant names profil_counter_* used in sprofil.c are also renamed to start with __ so that undesired function names do not get exported in static libc. As I noted in bug 17726, profil_counter should probably be a compat symbol on ARM and SPARC, so it wouldn't exist at all in static libc even as a weak alias. Since defining a compat symbol still requires an internal name as a target of an alias, this patch still seems reasonable as an intermediate step towards that goal: it wouldn't be possible for the function simply to be static profil_counter on ARM and SPARC with profil_counter also being the exported compat symbol name, so profil.c / sprofil.c would still need to be prepared to call the function under another name (here, __profil_counter). Tested for x86_64 (testsuite, and that stripped installed shared libraries are unchanged by the patch) and ARM (ABI and linknamespace tests - this patch reduces the number of linknamespace failures I see on ARM from 227 to 5, the residue being math.h failures for fe* functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases). 2014-12-17 Joseph Myers <joseph@codesourcery.com> [BZ #17725] * sysdeps/generic/profil-counter.h (profil_counter): Rename to __profil_counter. * sysdeps/unix/sysv/linux/hppa/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/i386/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/ia64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/sh/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/tile/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/x86_64/profil-counter.h (profil_counter): Likewise. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Likewise.

* Fix resolver inet_* namespace (bug 17722).Joseph Myers2014-12-178-12/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parts of the resolver brought in by pthreads (at least) use inet_* functions that aren't in the 1995/6 edition of POSIX that introduced pthreads (or in one case, use __inet_aton which is then defined in the same file as non-weak inet_addr). This patch fixes this by making the affected functions into weak alias for __inet_* and using those names in the problematic resolver code. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

* Fix x86_64 memrchr namespace (bug 17719).Joseph Myers2014-12-164-8/+14
| | | | | | | | | | | | | | | | | | | | | | | On x86_64, memrchr (not a standard function) is defined as a strong symbol, instead of a weak alias of __memrchr as on other architectures. This results in linknamespace test failures from the use of __memrchr from dirname. (Not a conformance issue because of the mem* reservation, but contrary to glibc conventions.) This patch makes x86_64 follow other architectures by defining memrchr as a weak alias. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17719] * sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and define as weak alias of __memrchr.

* Fix resolver if_* namespace (bug 17717).Joseph Myers2014-12-168-31/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolver code, brought in by pthreads (at least), uses if_* interfaces that weren't in POSIX before 2001, resulting in linknamespace failures. This patch changes those interfaces to be weak aliases of __if_* and makes the resolver use __if_* directly. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch).

* Fix the 'array subscript is above array bounds' warning correctlySiddhesh Poyarekar2014-12-162-1/+10

* Fix 'array subscript is above array bounds' warning in res_send.cSiddhesh Poyarekar2014-12-162-1/+6
| | | | | | | | | | I see this warning in my build on F21 x86_64, which seems to be due to a weak check for array bounds. Fixed by making the bounds check stronger. This is not an actual bug since nscount is never set to anything greater than MAXNS. The compiler however does not know this, so we need the stronger bounds check to quieten the compiler.

* Move semaphore.h to sysdeps/pthread/.Joseph Myers2014-12-113-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Carlos reported failures in conform/ tests in environments where the compiler used could only find headers in glibc's source and build trees, not any previously installed headers <https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>. This patch moves nptl/semaphore.h to sysdeps/pthread/semaphore.h so that it can be found by builds from all glibc subdirectories; it's not in any way NPTL-specific. (I left the Makefile setting to install this header in nptl/, but maybe it should move as well - it's just not clear to me what ifeq ($(subdir),...) conditional should be used to select the directory to associate the header with for installation purposes. The path in the toplevel Makefile used for begin-end-check also remains hardcoded; it's a known todo issue to rework that test to run in each subdirectory checking the headers installed from that subdirectory, rather than a separate hardcoded list.) Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). I did *not* test a configuration such as that in which Carlos saw failure. * nptl/semaphore.h: Move to ... * sysdeps/pthread/semaphore.h: ... here. * Makefile (installed-headers): Change nptl/semaphore.h to sysdeps/pthread/semaphore.h.

* Add more headers to include/ for conform tests.Joseph Myers2014-12-113-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Carlos reported failures in conform/ tests in environments where the compiler used could only find headers in glibc's source and build trees, not any previously installed headers <https://sourceware.org/ml/libc-alpha/2014-09/msg00040.html>. This patch adds wrappers for two of the affected headers to include/, which is the normal way to make headers visible when building or testing in directories other than the one containing the header (I suppose these headers weren't needed in any such directories except conform/, or other build or test failures would have resulted). I believe the same issue applies at least to regexp.h and re_comp.h - we don't currently have conform/ expectations for those, but when such expectations are added we'll also need to add header wrappers. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). I did *not* test a configuration such as that in which Carlos saw failure. * include/cpio.h: New file. * include/fmtmsg.h: Likewise.
