#7249 Changes/glibc 2.27, gcc 8.0, binutils 2.30
Closed: Fixed 7 months ago Opened a year ago by codonell.

All Fedora releases must be released using a released and supported version of the core toolchain involving glibc, gcc, and binutils.

The Fedora toolchain team is responsible for ensuring that Fedora Rawhide stabilizes static linking, code generation, and library ABI, before a Fedora release, or that after the branch that the Fedora release is rebased (a very small rebase) to the final released version. This is a requirement for Fedora to inherit the ABI and API guarantees provided by upstream. If a mass rebuild is required by binutils, gcc, glibc or other components, the Fedora toolcahin team will ensure coordination with release engineering such that a mass rebuild uses the released version of all components and fix any last minute ABI or code-generation changes.

As of 2018-01-08 the Fedora toolchain team is requesting a mass rebuild for the Fedora 28 release.

Reasons given:

  • Enable Intel CET for current and all future revisions of Fedora (compile with CET turned on).
  • Hardening flags injection for security purposes.
  • Test coverage of flags injection for Annobin, getting as much of the distribution built with annotated binaries for security hardening checking.

RelEng acknowledges the change and we will include this in the mass rebuild.

I believe the subject is in error, we will use binutils 2.29.1 for the Fedora 28 mass rebuild.

Note however that there are some open issues with the build flags.

The subject is indeed in error, I wrote 2.30 when I should have written 2.29.1

My apologies for the confusion.

@fweimer and @codonell with that all cleared up - are all of these pieces ready to go now?

Just want to clarify so I know I am not misinterpreting the comments from the other open rebuild ticket for gcc.

@kellin Everything is clear from my perspective, but please wait for the sign-off from @jakub as well if possible (there are many pending gcc fixes to arrive soon from upstream, but no Fedora build is current running).
