[correct would have been howmany(...), use IEEE80211_CHAN_BYTES,
which is used in the other ioctl method. While here s/u_char/u_int8_t/
for chanlist to match the rest of the uses.
ic->ic_bss, but it uses the rateset in its new ieee80211_node
argument, instead. If the rate is fixed by ic->ic_fixed_rate, but
the fixed rate is not in the node's rateset, choose a reasonable
default: prefer the lowest basic rate or, if there is no basic
rate, prefer the lowest rate, period.
Change a printf complaint to a debug message.
Adapt drivers to suit new ieee80211_get_rate calling convention.
XXX I really need to replace ieee80211_get_rate with a bitrate
XXX adaptation algorithm. Soon, soon....
sam@ and various open source repositories:
ath(4):
Ignore "phantom" beacon misses: should stabilize connections
to access points (no more ceaseless link-UP/DOWN indications).
Also, re-synchronize beacon timer using the TSF in the
first beacon received after joining a BSS---this should
also help suppress spurious beacon misses. I am hopeful
that this will help ath(4) lossage reported by perry@ and
smb@.
Add new configuration through sysctl.
Use a shorter calibration interval until IQ calibration
finishes.
Report antenna noise through radiotap.
Rudiments of Radar Detection / Dynamic Frequency Selection.
Update to HAL version 0.9.16.13.
Update open sources for changes to the HAL API.
Add HALs for additional architectures: add big-endian ELF
HALs for sparc64 and for PowerPC. Also add a Alpha HAL.
These new HALs are untested under NetBSD.
ath(4) + net80211:
Make the multicast transmit rate configurable by ioctl.
Miscellaneous bug fixes.
set the mgt frame tx timer before dispatching the frame to the
driver; this closes a race where a response could be processed
before the timer was started and cause a RUN->SCAN state change
when operating in station mode
lenght calculation phase instead of just growing the buffer like the older
patch did. I am leaving the bigger buffer too for now since it does not hurt.
Change -1 to named constant IEEE80211_FIXED_RATE_NONE. ic_fixed_rate
is an index into the ic_sup_rates table, so lookup a fixed rate
there and search the ni->ni_rates table for it.
Duration and PLCP Length fields, and delete the abominable
atw_frame_setdurs() subroutine.
Make rtw(4) use the new ieee80211_compute_duration() calling
convention.
Add an ieee80211_key argument to ieee80211_compute_duration() and
lightly constify arguments. Get the crypto header length from the
key argument instead of blithely assuming a WEP header. Add some
inline documentation. Account for data padding (IEEE80211_F_DATAPAD).
ieee80211_recv_mgmt(). ieee80211_update_adhoc_node() updates IBSS
nodes based on received beacons and probe responses. I extract a
subroutine to maintain a tolerable indentation level.
BSSID is set.
In IBSS mode, if the BSS node's BSSID changes, and a desired BSSID
is *not* set, make a RUN->RUN transition to give the driver an
opportunity to reprogram its BSSID filter. This fixes a bug where
both wlanctl(8) and ifconfig(8) indicated that an interface had
joined a new BSS, but no packets would get through, except in
promiscuous mode, because the hardware still filtered packets based
on the old BSSID.
If the operator did not configure a "desired BSSID," then we simply
adopt the BSS node's new BSSID. If the operator configured a
"desired BSSID," the new BSSID is (probably) not the desired one,
so start scanning for it.
Note that a change of BSSID will occur as two ad hoc networks merge.
node. It's the right thing to do, but it is of pressing importance
because SampleRate's ath_rate_ctl_reset() will convert an unsupported
rate to an invalid rate-index of 0xff, and pass the index to
ath_hal_computetxtime(). ath_hal_computetxtime() does not tolerate
an invalid index; the CPU traps a divide-by-zero fault in
ath_hal_computetxtime().
to 0x1 instead of 0xffff, so the kernel will trap accidental
dereferences. I don't set IEEE80211_CHAN_ANYC to NULL because it
may have a distinct meaning in net80211. Thanks to Steve Woodford
for pointing out that 0xffff may be a valid kernel memory address
on x86.
1 Complete initialization of "faked up" ieee80211_nodes,
whose capabilities and other fields are wrong, when we
first receive a beacon or probe response from the
corresponding neighbor. This entails factoring
ieee80211_init_neighbor out of ieee80211_add_neighbor.
2 In adhoc mode, ic->ic_bss is present in the neighbors
table, ic->ic_sta, and it is not necessarily the wrong
node on which to mark statistics for a rx'd packet. Do
not reject ic->ic_bss and fake-up a new node without
comparing its MAC address with the address of the sender
in the rx'd packet. This fixes a memory leak.
