Firmware, kernel module or userspace? :)

No clue on firmware, I'm not exactly sure how to check which is being
loaded...
Did you mention an exact hardware in question?
02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235
(rev
24)
Subsystem: Intel Corporation Centrino Advanced-N 6235 AGN

Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
BTW how are you sure RF environment ain't changed?
Nothing new has come in or left the house since the problem...
Thanks,
Richard
- KERNEL:
$ curl -s https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.6
| grep iwlwifi
So pick up kernel-3.14.6-200.fc20.x86_64.rpm
http://koji.fedoraproject.org/koji/buildinfo?buildID=531773
You can also try with kernel-core-3.15.0-1.fc21.x86_64.rpm
http://alt.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/x86_64/
- FIRMWARE:
$ modinfo -F firmware iwlwifi
# yum --enablerepo updates-testing install iwl6000g2b-firmware
$ rpm -qf /usr/lib/firmware/iwlwifi-6000g2b-6.ucode
iwl6000g2b-firmware-17.168.5.2-38.fc20.noarch
According to
http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
Intel® Centrino® Advanced-N 6235 goes with
iwlwifi-6000g2b-ucode-18.168.6.1.tgz
i.e. iwlwifi-6000g2b-6.ucode
also stated within firmware itself:
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-6000g2b-6.ucode
"IWL.6000g2b.fw.v18.168.6.1.build.0"
However in Fedora it is packaged as "17" i.e.
iwl6000g2b-firmware-17.168.5.2-38.fc20.noarch
Probably because I forgot to increment the version number.
Josh, do these two firmwares should be in their own packages as "18"?
No.
Intel® Centrino® Advanced-N 6235 - iwlwifi-6000g2b-ucode-18.168.6.1
i.e. iwlwifi-6000g2b-6.ucode - "IWL.6000g2b fw v18.168.6.1 build 0"
in iwl6000g2b-firmware-18.168.6.1-1.f$releasever.noarch.rpm
and
Intel® Centrino® Advanced-N 6205 - iwlwifi-6000g2a-ucode-18.168.6.1
i.e. iwlwifi-6000g2a-6.ucode - "IWL.6000g2a fw v18.168.6.1 build 0"
in iwl6000g2a-firmware-18.168.6.1-1.f$releasever.noarch.rpm
e.g.
- Intel® Centrino® Advanced-N 6235
1. Rename
iwl6000g2b-firmware-17.168.5.2-38.fc20.noarch
to
iwl6000g2b5-firmware-17.168.5.2-38.fc20.noarch
/usr/lib/firmware/iwlwifi-6000g2b-5.ucode
2. Create
iwl6000g2b6-firmware-18.168.6.1-1.f20.noarch.rpm
/usr/lib/firmware/iwlwifi-6000g2b-6.ucode
- Intel® Centrino® Advanced-N 6205
3. Rename
iwl6000g2a-firmware-17.168.5.3-38.fc20.noarch
to
iwl6000g2a5-firmware-17.168.5.3-38.fc20.noarch
/usr/lib/firmware/iwlwifi-6000g2a-5.ucode
4. Create
iwl6000g2a6-firmware-18.168.6.1-1.f20.noarch.rpm
/usr/lib/firmware/iwlwifi-6000g2a-6.ucode
No. That's really pointless work and makes the linux-firmware package
even more complicated that it already is.
The firmware is getting installed and it's correct. Most times people
don't need to worry about which firmware they have, and if they do they
can consult the WHENCE file installed in /usr/share/doc/linux-firmware/.

IF I correctly understood
http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
Fedora is shipping at least one unnecessary firmware version compared to the
kernels used,
e.g. for
Intel® Centrino® Advanced-N 6205
IS required only iwlwifi-6000g2a-6.ucode - kernel 3.2+
and NOT iwlwifi-6000g2a-5.ucode - kernel 2.6.35+
Fedora ships whatever is in the upstream linux-firmware git repo in
the linux-firmware package. It's stand-alone. We don't tie it to the
kernel versions in Fedora. People do strange things like running
their own kernels on top of a Fedora OS install all the time.
josh
Someone's always talking about how to reduce the burden on the packages, but it seems that this is not the case.
These people should be able to download a firmware tarball for themselves when they are already using ancient kernels. :)
Sugway!
