These people are interested in contents and further revisions tagged on the branch:

The general policies for release branches apply to this branch. Do you think a certain bugfix should be included in this branch?

  1. Is the fix committed in master? It has to be, unless it's not applicable to master (e.g. code has been rewritten meantime).
  2. Do you have commit permissions? If so, go ahead if you think it's reasonably safe. break;
  3. Can you handle Git yourself? Then you can clone the glibc repository, cherry-pick the appropriate fixes, push your branch out and send a pull request at libc-alpha. break;
  4. Add the glibc_2.17 keyword to the appropriate bug report.
  5. If there is no appropriate bug report, send a request for the fix to be included to libc-alpha.

A revision release is tagged either when some critical bug-fix appears, or after some period of real-world testing, usually mainly in some SUSE distribution branch (but other distributions are welcome to run latest release/2.17/master as well, more so if they tell me about it!).

This is a kernel race, where it is unable to reap the exiting thread fast enough. This is seen regularly on x86_64, but the root cause is not necessarily architecture specific.

Packaging Changes

Due to changes in the installed headers and the libraries itself, userland applications might not build anymore. The following problems have been noticed while rebuilding distributions like openSUSE:
