In <https://sourceware.org/ml/libc-alpha/2016-01/msg00885.html> I proposed a minimum Linux kernel version of 3.2 for glibc 2.24, since Linux 2.6.32 has reached EOL. In the discussion in February, some concerns were expressed about compatibility with OpenVZ containers. It's not clear that these are real issues, given OpenVZ backporting kernel features and faking the kernel version for guest software, as discussed in <https://sourceware.org/ml/libc-alpha/2016-02/msg00278.html>. It's also not clear that supporting running GNU/Linux distributions from late 2016 (at the earliest) on a kernel series from 2009 is a sensible expectation. However, as an interim step, this patch increases the requirement everywhere except x86 / x86_64 (since the controversy was only about those architectures); the special caveats and settings can easily be removed later when we're ready to increase the requirements on x86 / x86_64 (and if someone would like to raise the issue on LWN as suggested in the previous discussion, that would be welcome). 3.2 kernel headers are required everywhere by this patch. (x32 already requires 3.4 or later, so is unaffected by this patch.) As usual for such a change, this patch only changes the configure scripts and associated documentation. The intent is to follow up with removal of dead __LINUX_KERNEL_VERSION conditionals. Each __ASSUME_* or other macro that becomes dead can then be removed independently. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Define to 3.2.0. (arch_minimum_kernel): Likewise. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Define to 2.6.32. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Define to 2.6.32. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Document Linux 3.2 requirement. * manual/install.texi (Linux): Document Linux 3.2 headers requirement. * INSTALL: Regenerated. |
