Whilst not strictly a NM problem, am posting here as (a) Dan's follows
this list and (b) I'd expect this to hit other NM users.
After upgrading from FC6 to F7, I noticed that I was unable to connect
to my office WPA2 network. With some digging, I traced the problem to
wpa_supplicant segfaulting as when it tries to hexdump a large RX EAPOL
frame.
This is caused by the redhat wpa_supplicant-0.5.7-use-syslog.patch
overflowing a 2KBoutput buffer. The frame that's causing the error for
me is 1400 bytes. When displayed in a "RX EAPOL - hexdump(len=1400): 00
00 00" string, this requires a little over 4KB. This patch in this mail
just increases the buffer size to 8KB, however I suspect there ought to
be some boundary checking going on.
Dan, is reporting here sufficient, or would a bugzilla entry help get
this fixed?
Regards,
Jon.
