Red Hat Bugzilla – Bug 427843
Backport the 'fragment_size' option
Last modified: 2008-05-21 13:33:38 EDT
We need to backport the 'fragment_size' config option to RHEL5's wpa_supplicant
0.4.8. Without the ability to set the EAP fragment size to 1300 or less, we
cannot successfully negotiate WPA Enterprise connections with the Cisco test
hardware we have in-house; the authentication process just hangs. The change
won't affect the _default_ fragment size, so default behavior is the same as
before, but NetworkManager for example would set a lower fragment size than the
default to ensure success on a wider range of AP hardware.
Patch attached; tested with RHEL 5.1 on Dell Precision M6300 with ipw3945 and
Created attachment 291004 [details]
backport of 'fragment_size' config option from 0.5.9
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
QE: we've got all the hardware in-house and it's trivially easy to test as I've
already got everything set up for WPA Enterprise stuff. Testing is just trying
a wpa_supplicant config file with a network block for EAP-TLS both with and
without the 'fragment_size=1300' option against a WPA-EAP setup.
Changes committed to RHEL5 branch
Verified with new NM & new wpa_supplicant on Dell precision M6300.
