Make the transmit section reserve one descriptor for issuing a
command at all times. If either transmit descriptors run out, or
header/buffer software descriptors run out, set IFF_OACTIVE and
get out of ipw_start, rather than re-using a descriptor or trying
to use a NULL descriptor that comes off the front of an empty
descriptor tailqueue.
This ought to fix port-i386/27439 and kern/28683.
create and queue a new one that carries the new BSSID. I mined
net80211 in FreeBSD for the solution, which is to make an
IEEE80211_S_RUN->IEEE80211_S_RUN state transition---ath_newstate
discards the old beacon packet creates a new one by calling
ath_beacon_alloc.
I tested the merge as follows. Starting at my desk on the second
floor of the building where I work:
soekris% ifconfig ath0 mediaopt adhoc ssid zzz chan 11 down
powerbook% ifconfig rtw0 mediaopt adhoc ssid zzz chan 11 up
soekris% sleep 25; ifconfig ath0 up
I raced to the elevator with my Powerbook, pressed the "Down"
button, got in, and pressed "Floor 1." At the first floor:
powerbook% ifconfig rtw0 | grep bssid
bssid 02:p:p:p:p:p chan 11
I waited 25 seconds. I pressed "Floor 2." At Floor 2, I returned to my desk.
I checked to make sure that the Soekris console read:
soekris% ath0: creating bss 02:s:s:s:s:s
ath0: bss merge 02:s:s:s:s:s -> 02:p:p:p:p:p
0:s:s:s:s:s is the Soekris' WLAN MAC. 0:p:p:p:p:p is the Powerbook's
WLAN MAC. Each created an ad hoc-mode BSSID from its WLAN MAC by
OR'ing 0x2 with the first octet.
My Powerbook created a network while the Soekris radio was off.
The Soekris radio turned on while I was in the 802.11-impervious
elevator with my Powerbook. When I returned to the second floor,
the Soekris "heard" beacons from my Powerbook as the elevator door
opened. Since the Powerbook's network was approximately 25 seconds
older than the Soekris', and since it had the same SSID (zzz) as
the Soekris', the Soekris merged with the Powerbook's network (by
setting its BSSID) as it should.
and collapse the two variations of obio into one. use the remaining locator
("addr") to differentiate the two possible esp and sbc devices (instead of
using the unit number).
${MAKE} ${CRUNCHENV} ...
instead of
${CRUNCHENV} ${MAKE} ...
so that CRUNCHENV overrides any user-provided command-line make(1) variables.
This fixes /rescue build problems for people who pass settings such
as MKKERBEROS=yes in via the make(1) command-line.
