rekeying of GTK and PTK completely broken under network load

[Andreas Hartmann]

Hello!

Could you please take a look at this bugreport:

http://w1.fi/bugz/show_bug.cgi?id=402


I'm not really sure, if this really is a hostapd bug or a bug somewhere
else!


The tests I did where done with the following hardware:

hostapd:

03:07.0 Network controller: RaLink RT2800 802.11n PCI
        Subsystem: Linksys Device 0067
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx-
        Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 32 (500ns min, 1000ns max), Cache Line Size: 4 bytes
        Interrupt: pin A routed to IRQ 21
        Region 0: Memory at fdce0000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [40] Power Management version 3
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA
PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME-
        Kernel driver in use: rt2800pci


-> this is a Linksys WMP600N with a ralink RT2860 / RT2850 chip (see

The supplicants in use where:

wext-driver with rt3572sta (Linksys WUSB600Nv2 rt3572

nl80211-driver with AR9285 (PCIE-device of a laptop)


Thank you,
