  • Bug#1108270: linux: uname -r contains regex control character '+'

    Source: linux
    Version: 6.12.33-1

    Dear Maintainer(s),

    Since version 6.12.33-1 uname -r contains the regex control character
    '+'. This means any existing script passing the output of $(uname -r)
    to anything that can interpret it as a regex will start to fail.

    e.g. on unstable where uname -r is 6.12.33+deb13-amd64:

    $ [[ "My List Of Favourite Kernels: 6.1.31 3.2 2.6.31318231
    6.12.27-amd64 6.12.33+deb13-amd64" =~ $(uname -r) ]]; echo $?
    1

    On testing where uname -r is 6.12.27-amd64:

    $ [[ "My List Of Favourite Kernels: 6.1.31 3.2 2.6.31318231
    6.12.27-amd64 6.12.33+deb13-amd64" =~ $(uname -r) ]]; echo $?

    0

    I can fix my autopkgtest scripts that started failing due to this, but
    it seems to me it might affect more scripts out there, so filing a bug
    so that there's something indexed and searchable.

    It also contains the control character '.', multiple times.

    Sure, still closing as wontfix, as we have no other characters left.
