* nptl: Change type of __default_pthread_attrFlorian Weimer2020-06-028-15/+14
| | | | | | | | | | | | union pthread_attr_transparent has always the correct size, even if pthread_attr_t has padding that is not present in struct pthread_attr. This should not result in an observable behavioral change. The existing code appears to have been correct, but it was brittle because it was not clear which functions were allowed to write to an entire pthread_attr_t argument (e.g., by copying it).

* mbstowcs: Document, test, and fix null pointer dst semantics (Bug 25219)Carlos O'Donell2020-06-014-6/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function mbstowcs, by an XSI extension to POSIX, accepts a null pointer for the destination wchar_t array. This API behaviour allows you to use the function to compute the length of the required wchar_t array i.e. does the conversion without storing it and returns the number of wide characters required. We remove the __write_only__ markup for the first argument because it is not true since the destination may be a null pointer, and so the length argument may not apply. We remove the markup otherwise the new test case cannot be compiled with -Werror=nonnull. We add a new test case for mbstowcs which exercises the destination is a null pointer behaviour which we have now explicitly documented. The mbsrtowcs and mbsnrtowcs behave similarly, and mbsrtowcs is documented as doing this in C11, even if the standard doesn't come out and call out this specific use case. We add one note to each of mbsrtowcs and mbsnrtowcs to call out that they support a null pointer for the destination. The wcsrtombs function behaves similarly but in the other way around and allows you to use a null destination pointer to compute how many bytes you would need to convert the wide character input. We document this particular case also, but leave wcsnrtombs as a references to wcsrtombs, so the reader must still read the details of the semantics for wcsrtombs.

* elf: Remove extra hwcap mechanism from ldconfigFlorian Weimer2020-05-281-71/+16
| | | | | | | | | | | | | | Historically, this mechanism was used to process "nosegneg" subdirectories, and it is still used to include the "tls" subdirectories. With nosegneg support gone from ld.so, this is part no longer useful. The entire mechanism is not well-designed because it causes the meaning of hwcap bits in ld.so.cache to depend on the kernel version that was used to generate the cache, which makes it difficult to use this mechanism for anything else in the future.
