* Fix csqrt missing underflows (bug 18370).Joseph Myers2015-08-191-2/+2
| | | | | | | | | | | | | | | | | | | The csqrt implementations in glibc can miss underflow exceptions when the real or imaginary part of the result becomes tiny in the course of scaling down (in particular, multiplication by 0.5) and that scaling is exact although the relevant part of the mathematical result isn't. This patch forces the exception in a similar way to previous fixes. Tested for x86_64 and x86.

* Fix csqrt spurious underflows (bug 18823).Joseph Myers2015-08-171-1/+1
| | | | | | | | | | | | | | | | | | The csqrt functions scale up small arguments to avoid underflows when calling hypot functions. However, even when hypot does not underflow, a subsequent calculation of 0.5 * hypot can underflow. This patch duly increases the threshold and scale factor to avoid such underflows as well. Tested for x86_64, x86 and mips64.

* stpncpy: fix size checking [BZ #18975]Zack Weinberg2015-08-141-2/+2
| | | | | | | | | | I think the last clause of the conditional, || __n <= __bos (__dest) may be backward. The code should call the runtime-checking function if __n is not constant, or if __n is known to be LARGER than the size of the destination.
* Fix fma spurious underflows (bug 18824).Joseph Myers2015-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various fma implementations have logic that, when computing fma (x, y, z) where z is large (so care needs taking to avoid internal overflow) but x * y is small, scale x * y up instead of down to avoid internal underflows resulting from scaling down. (In these cases, x * y is small enough that only its sign actually matters rather than the exact value.) The threshold for scaling up instead of down was correct for "if the unscaled values were multiplied, the low part of the multiplication could underflow", and the scaling was sufficient to ensure that the low part of the multiplication did not underflow (given that cases of very small x * y - less than half the least subnormal - were previously dealt with). However, the choice in the functions wasn't between scaling up or no scaling, but between scaling up and scaling down (scaling down actually being needed when x * y isn't so small compared to z and so the exact value does matter). Thus a larger threshold is needed to ensure that scaling down doesn't produce values the multiplication of whose low parts underflows. This patch increases the thresholds accordingly. Tested for x86_64, x86 and mips64 (with the MIPS version of s_fmal.c removed so that the ldbl-128 version gets tested instead of the soft-fp one).

* Deprecate the use of regexp.hZack Weinberg2015-08-011-0/+8
| | | | | | | | | | | | | | | | | | <regexp.h> (not to be confused with <regex.h>) is an obsolete and frankly horrible regular expression-matching API. It was part of SVID but was withdrawn in Issue 5 (for reference, we're on Issue 7 now). It doesn't do anything you can't do with <regex.h>, and using it involves defining a bunch of macros before including the header. Moreover, the code in regexp.h that uses those macros has been buggy since its creation (in 1996) and no one has noticed, which indicates to me that there are no users. (Specifically, RETURN() is used in a whole bunch of cases where it should have been ERROR().) The header is given a warning and marked deprecated for 2.22. See: https://sourceware.org/ml/libc-alpha/2015-07/msg00862.html and https://sourceware.org/ml/libc-alpha/2015-07/msg00871.html.

* Use IE model for static variables in libc.so, libpthread.so and rtldSiddhesh Poyarekar2015-07-241-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recently introduced TLS variables in the thread-local destructor implementation (__cxa_thread_atexit_impl) used the default GD access model, resulting in a call to __tls_get_addr. This causes a deadlock with recent changes to the way TLS is initialized because DTV allocations are delayed and hence despite knowing the offset to the variable inside its TLS block, the thread has to take the global rtld lock to safely update the TLS offset. This causes deadlocks when a thread is instantiated and joined inside a destructor of a dlopen'd DSO. The correct long term fix is to somehow not take the lock, but that will need a lot deeper change set to alter the way in which the big rtld lock is used. Instead, this patch just eliminates the call to __tls_get_addr for the thread-local variables inside libc.so, libpthread.so and rtld by building all of their units with -mtls-model=initial-exec. There were concerns that the static storage for TLS is limited and hence we should not be using it. Additionally, dynamically loaded modules may result in libc.so looking for this static storage pretty late in static binaries. Both concerns are valid when using TLSDESC since that is where one may attempt to allocate a TLS block from static storage for even those variables that are not IE. They're not very strong arguments for the traditional TLS model though, since it assumes that the static storage would be used sparingly and definitely not by default. Hence, for now this would only theoretically affect ARM architectures. The impact is hence limited to statically linked binaries that dlopen modules that in turn load libc.so, all that on arm hardware. It seems like a small enough impact to justify fixing the larger problem that currently affects everything everywhere. This still does not solve the original problem completely. That is, it is still possible to deadlock on the big rtld lock with a small tweak to the test case attached to this patch. That problem is however not a regression in 2.22 and hence could be tackled as a separate project. The test case is picked up as is from Alex's patch. This change has been tested to verify that it does not cause any issues on x86_64. ChangeLog: [BZ #18457] * nptl/Makefile (tests): New test case tst-join7. (modules-names): New test case module tst-join7mod. * nptl/tst-join7.c: New file. * nptl/tst-join7mod.c: New file. * Makeconfig (tls-model): Pass -ftls-model=initial-exec for all translation units in libc.so, libpthread.so and rtld.
* Also use l_tls_dtor_count to decide on object unload (BZ #18657)Siddhesh Poyarekar2015-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an TLS destructor is registered, we set the DF_1_NODELETE flag to signal that the object should not be destroyed. We then clear the DF_1_NODELETE flag when all destructors are called, which is wrong - the flag could have been set by other means too. This patch replaces this use of the flag by using l_tls_dtor_count directly to determine whether it is safe to unload the object. This change has the added advantage of eliminating the lock taking when calling the destructors, which could result in a deadlock. The patch also fixes the test case tst-tls-atexit - it was making an invalid dlclose call, which would just return an error silently. I have also added a detailed note on concurrency which also aims to justify why I chose the semantics I chose for accesses to l_tls_dtor_count. Thanks to Torvald for his help in getting me started on this and (literally) teaching my how to approach the problem. Change verified on x86_64; the test suite does not show any regressions due to the patch. ChangeLog: [BZ #18657] * elf/dl-close.c (_dl_close_worker): Don't unload DSO if there are pending TLS destructor calls. * include/link.h (struct link_map): Add concurrency note for L_TLS_DTOR_COUNT. * stdlib/cxa_thread_atexit_impl.c (__cxa_thread_atexit_impl): Don't touch the link map flag.

* sparc: fix sigaction for 32bit builds [BZ #18694]Mike Frysinger2015-07-201-1/+5
| | | | | | | | | | | Commit a059d359d86130b5fa74e04a978c8523a0293f77 changed the sigaction struct to pass conform tests, but it ended up also changing the ABI for 32 bit builds. For 64 bit builds, changing the long to two ints works, but for 32 bit builds, it inserts 4 extra bytes. This leads to many packages randomly failing like bash that spews things like: configure: line 471: wait_for: No record of process 0 Bracket the new member by a wordsize check to fix the ABI for 32bit.

* Preserve bound registers for pointer pass/returnIgor Zamyatin2015-07-091-7/+7
| | | | | | | | | | | | | | | | | | | | | | | We need to save/restore bound registers and add a BND prefix before branches in _dl_runtime_profile so that bound registers for pointer pass and return are preserved when LD_AUDIT is used. [BZ #18134] * sysdeps/i386/configure.ac: Set HAVE_MPX_SUPPORT. * sysdeps/i386/configure: Regenerated. * sysdeps/i386/dl-trampoline.S (PRESERVE_BND_REGS_PREFIX): New. (_dl_runtime_profile): Save and restore Intel MPX return bound registers when calling _dl_call_pltexit. Add PRESERVE_BND_REGS_PREFIX before return. * sysdeps/i386/link-defines.sym (LRV_BND0_OFFSET): New. (LRV_BND1_OFFSET): Likewise. * sysdeps/x86/bits/link.h (La_i86_retval): Add lrv_bnd0 and lrv_bnd1. * sysdeps/x86_64/dl-trampoline.S (_dl_runtime_profile): Fix typo in bndmov encoding. * sysdeps/x86_64/dl-trampoline.h: Properly save and restore Intel MPX bound registers. Add PRESERVE_BND_REGS_PREFIX before branch instructions to preserve bounds.
