Description Nicolas Chauvet (kwizart) 2026-02-03 08:44:23 UTC

When building some i686 asm code in fedora and 3rd part, there are many occurence of the following errors.

/usr/bin/ld.bfd: common/x86/dct-a-8.o: warning: relocation in read-only section `.text'
/usr/bin/ld.bfd: error: read-only segment has dynamic relocations


Affected packages so far in Fedora:
ffmpeg (free)
xvidcore
patchelf

3rd part:
ffmpeg
x265
x264
...

Reproduced with current binutils in f44 and newer (still in testing) binutils-2.45.90-1.fc44

Reproducible: Always

Current workaround is to use LDFLAGS+="-Wl,-z,notext"

Hi Nicolas,

This change is a result of this ticket.

https://bugzilla.redhat.com/show_bug.cgi?id=2428281

Allowing relocations against read-only segments is a potential security vulnerability, which is why the change was made.  As you have mentioned using "-W,-z,notext" will work around this problem, although if this is done it would be useful to include a comment explaining why the vulnerability is not important.

I would like to close this ticket as NOT-A-BUG or possibly as a DUPLICATE.  Do you agree to this ?

Cheers
  Nick

Comment 3 Nicolas Chauvet (kwizart) 2026-02-03 15:51:51 UTC

Thanks for the infos on this.
This seems a duplicate of your mentioned bug.

That said xvidcore (or others) obviously always had this issue on i686, and none bothered. (or not loud enough).
If now making the build fails and it's only detected by the mass-rebuild, then this leave very few time for a better fix.

And having a build failing means some underlying dependencies might fail to land in-time for f44.

I will try to do by best to land the appropriate fix though.
Thanks again for the answer.
