Release/2.25

1. Current status

The release branch of glibc-2.25 is maintained by Siddhesh Poyarekar and was released on 2017-02-05. There are no immediate plans for the next release.

The ref structure of this branch is:

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_2.25 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/2.25/master as well, more so if they tell me about it!).

2. Planning

3. Known Issues

3.1. Build and test issues

Describe build and test issues for each architecture, or confirm a clean build with no testsuite failures. The list below is not a complete list of ABI variants; testing should try to cover the different ABI variants as far as possible.

GCCs >= 4.9 and <= 5.3 saves r15 in a floating-point register in do_sigwait() and emits false cfi information. If a thread is cancelled while sigwait blocks, unwinding has already stopped before the function with the cleanup-handler. See gcc commits "S/390: Fix cfi for GPR 2 FPR saves" in gcc 4.9 branch, gcc 5 branch and gcc 6 branch. This occures if built with -O2. With -O3, r15 is not saved in fpr here and the test passes.

3.1.25. x86 (32-bit, Hurd)

3.2. Packaging Changes

3.2.1. sys/types.h and sys/sysmacros.h

The inclusion of sys/sysmacros.h by sys/types.h is deprecated. Using the macros major, minor, or makedev without having directly included sys/sysmacros.h will trigger compiler warnings.

These macros are not part of POSIX nor XSI, and their names frequently collide with user code; see for instance glibc bug 19239 and Red Hat bug 130601. stdlib.h includes sys/types.h under _GNU_SOURCE, and C++ code presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the problem.

Most programs do not need these macros. Programs that wish to use their names for their own purposes should #undef all three after including all system headers:

   1 #include <sys/types.h>
   2 #include <stdio.h>
   3 /* ... more headers ... */
   4 
   5 /* Some systems provide macros 'major', 'minor', 'makedev' in <sys/types.h>, which we don't want.  */
   6 #undef major
   7 #undef minor
   8 #undef makedev
   9 

Programs that do need these macros should arrange to get them either from sys/types.h or sys/sysmacros.h, because on BSD-derived systems, sys/sysmacros.h does not exist:

   1 #include <sys/types.h>
   2 #ifdef __GLIBC__
   3 #include <sys/sysmacros.h>
   4 #endif
   5 

In order to decide when sys/types.h can stop providing these macros altogether, we would appreciate reports of software affected by this deprecation.

Applications wishing to be compatible with older pre-2.25 glibc's may safely include sys/sysmacros.h starting with glibc 2.0 from 1997, when the header first appeared.

3.2.2. res_gethostbyaddr etc. compat symbols

glibc 2.25 turns res_gethostbyaddr, res_gethostbyname and other functions returning struct hostent results into compatibility symbols. These functions have not been included in the installed <resolv.h> header for a very long time, so applications should not access them. There implementations are also not updated for new DNS developments. There seem to be bogus autoconf checks for these functions (in ekiga, for example). If applications use these functions to avoid endless loops in host name lookups, they need to use __nss_configure_lookup instead.

None: Release/2.25 (last edited 2017-02-17 07:56:39 by FlorianWeimer)
