ld.so cleanup
by Waldemar Brodkorb 29 Jun '17

29 Jun '17

Hi, I would suggest following patch, which removes the special communication between ld.so and gdb. While debugging a ld.so issue with gdb 8.0 on alpha, I recognized that the debugger stalled when trying to execute this code. It thought this code was added to help debugging ld.so, but it seems nowadays it prevents to do so. May be bitrotted? Does anyone found it useful while debugging ld.so with gdb in the past? best regards Waldemar

[PATCH] include/features.h: add _DEFAULT_SOURCE macro
by Anthony G. Basile 22 Jun '17

22 Jun '17

From: "Anthony G. Basile" <blueness(a)gentoo.org> man feature_test_macros(7) specifies that _BSD_SOURCE and _SVID_SOURCE have been deprecated in favor of _DEFAULT_SOURCE since libc 2.20. Specifying either of the former is now equivalent to specifying just the latter. We add this macro to conform to this standard, but do not add the compiler warning to maintain full backwards compatibility with earlier version of glibc and uclibc. Signed-off-by: Anthony G.

[PATCH] Fix mkostemp64 creation mode.
by Ignacy Gawędzki 11 Jun '17

11 Jun '17

All flavors of mkstemp create files with mode S_IRUSR | S_IWUSR, as per POSIX.1-2008. Make mkostemp64 follow that too instead of creating files with mode S_IRUSR | S_IWUSR | S_IXUSR.

mkostemp64 creates files with mode 0700
by Ignacy Gawedzki 08 Jun '17

08 Jun '17

Hi, I just noticed today that mkostemp64 calls __gen_tempname with mode S_IRUSR | S_IWUSR | S_IXUSR, while all other flavors call it with mode S_IRUSR | S_IWUSR, as per POSIX.1-2008. See libc/stdlib/mkostemp64.c. I assume I don't need to send a patch for that. Cheers, Ignacy -- Ignacy Gawędzki R&D Engineer Green Communications
