[PATCH] include/sys/personality.h: resync with glibc
by Thomas Petazzoni 24 Apr '21

24 Apr '21

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 18 Apr '21

18 Apr '21

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 09 Apr '21

09 Apr '21

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..
