2017-08-16Fix sigval namespace (bug 21944).Joseph Myers
XPG4.2 defines the siginfo_t type, but not union sigval or its contents (which were added in the 1993 edition of POSIX.1), resulting in namespace violations for sigval, sival_int and sival_ptr for signal.h and sys/wait.h for that standard because those headers incorrectly expose those names in that case. This patch fixes this problem. The public type in this case is union sigval, but various places in the headers use the sigval_t name for it; direct uses of union sigval are already properly guarded or in headers not in XPG4.2. Now, sigval_t, although not a standard name, does seem to be widely used outside glibc. The approach taken by this patch is to make installed headers use the name __sigval_t instead. __sigval_t is then defined to either union sigval or union __sigval (where union __sigval has __-prefixed member names as well), depending on whether there are any namespace issues with the union sigval name and its members. In the case where union __sigval is used, sigval_t is not defined at all, to avoid the problem of sigval_t having a C++ mangled name that depends on feature test macros. sigval_t is still defined by signal.h if __USE_MISC (reflecting the nonstandard nature of that name). Tested for x86_64. [BZ #21944] * signal/bits/types/__sigval_t.h: New file. * signal/Makefile (headers): Add bits/types/__sigval_t.h. * signal/bits/types/sigval_t.h: Include <bits/types/__sigval_t.h> and define sigval_t using __sigval_t. * include/bits/types/__sigval_t.h: New file. * bits/types/sigevent_t.h: Include <bits/types/__sigval_t.h> instead of <bits/types/__sigval_t.h>.

2017-08-16Allow abort PLT references in libc.so for SH.Joseph Myers
Given my patch <https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the ICEs building a glibc string function test for SH, the testsuite can build completely for SH with GCC 7 and mainline. However, there is a test failure that does not appear for GCC 6: check-localplt fails because of an abort PLT reference in libc.so. Given the lack of a trap insn pattern for SH, it seems unavoidable that the compiler might sometimes generate abort calls, and such abort calls (generated from __builtin_trap when there is no trap insn pattern) will be unaffected by the normal mapping to __GI_abort for calls within glibc. Thus, this patch allows (but does not require) an abort PLT reference in libc.so for SH. Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my patch applied). * sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in libc.so.

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>.

2017-08-14posix: Fix mmap for m68k and ia64 (BZ#21908)Adhemerval Zanella
Default semantic for mmap2 syscall is to take the offset in 4096-byte units. However m68k and ia64 mmap2 implementation take in the configured pageunit units and for both architecture it can be different values. This patch fixes the m68k runtime discover of mmap2 offset unit and adds the ia64 definition to find it at runtime. Checked the basic tst-mmap and tst-mmap-offset on m68k (the system is configured with 4k, so current code is already passing on this system) and a sanity check on x86_64-linux-gnu (which should not be affected by this change). Sergei also states that ia64 loader now work correctly with this change. Adhemerval Zanella <adhemerval.zanella@linaro.org> Sergei Trofimovich <slyfox@inbox.ru> * sysdeps/unix/sysv/linux/m68k/mmap_internal.h (MMAP2_PAGE_SHIFT): Rename to MMAP2_PAGE_UNIT. * sysdeps/unix/sysv/linux/mmap.c: Include mmap_internal iff __OFF_T_MATCHES_OFF64_T is not defined. * sysdeps/unix/sysv/linux/mmap_internal.h (page_unit): Declare as uint64_t. (MMAP2_PAGE_UNIT) [MMAP2_PAGE_UNIT == -1]: Redefine to page_unit. (page_unit) [MMAP2_PAGE_UNIT != -1]: Remove definition.
2017-08-14i386: Do not set internal_functionFlorian Weimer
All calls to functions with the internal_function attribute have been removed from assembler implementations, which means that the definition of internal_function can be changed at the C level without causing ABI issues with assembler code. _dl_fixup still uses a regparm calling convention on i386, but this is controlled through ARCH_FIXUP_ATTRIBUTE, not internal_function.
2017-08-14_dl_init: Remove internal_function attributeFlorian Weimer
The function is called from the i386 startup code, which needs minor adjustments due to the changed ABI.
2017-08-14_dl_start: Remove internal_function attributeFlorian Weimer
The i386 startup code needs adjusting because it calls the function and the ABI has changed.
2017-08-14_dl_fini: Remove internal_function attributeFlorian Weimer
Assembler code passes the address of _dl_fini to __libc_start_main, whose function pointer argument lacks the attribute. This means that calls could use the wrong ABI. Fortunately, for zero-parameter void-returning functions, internal_function does not change ABI on i386 (the only architecture which uses internal_function), so this inconsistency was harmless (which is why it had not been noticed so far).

2017-08-12Locales: Use Unicode wise thousands separatorStanislav Brabec
Many languages use small gap as thousands separator. Thousands separator should not be a plain space, but a narrow space. And additionally, it is not allowed to wrap line in the middle of the number. Locale data were created in a deep age of 8-bit encodings, so most of them use space (incorrect: it allows wrapping the line in the middle of the number), or NBSP (better, but typographically incorrect: space between groups is too wide). Now UNICODE is widely supported, so we should leave legacy characters in favor of correct UNICODE character. UNICODE has a dedicated character for this purpose: NNBSP U+202F NARROW NO-BREAK SPACE: a narrow form of a no-break space, typically the width of a thin space or a mid space The NNBSP exists since Unicode 3.0. Use of NNBSP will prevent line wrapping in the midle of number and improve readability of numbers.
