Description Flags
backport of 'fragment_size' config option from 0.5.9 none

Description Dan Williams 2008-01-07 19:47:45 UTC 
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
Cisco AIR-AP-1131AG.

Comment 2 RHEL Program Management 2008-01-07 19:55:18 UTC 
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
release.
Comment 3 Dan Williams 2008-01-07 20:53:01 UTC 
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.
