[PATCH] include/sys/personality.h: resync with glibc

by Thomas Petazzoni

The trigger for this resync was ADDR_NO_RANDOMIZE, which was not defined in uClibc-ng, but is used for example by the uftrace project.

[PATCH] libpthread/nptl: create timer thread with sufficiant stack size (account for TLS)

by Peter Seiderer

Create timer thread with sufficiant stack size (take into account allocated space for thread-local-storage), for this backport glibc commit 'Create internal threads with sufficient stack size' ([1], [2]) introducing __pthread_get_minstack() and use it in __start_helper_thread(). Fixes timer_create() in case of linking with library using large TLS area (e.g openblas, see [3]).

[PATCH] open: Add support for O_TMPFILE

by Nicolas Cavallari

Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY) to make it fail on old kernels. Copying definitions from glibc for O_TMPFILE is not enough to support O_TMPFILE; The open() wrapper also need to pass the mode when the flag contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed but yield unexpected results. openat() is curiously not affected since it passes the mode unconditionally..
