This patch supersedes my previous patch "sky2: Avoid transmitting during sky2_restart". I have reworked the patch to avoid crashes during both sky2_restart() and sky2_set_ringparam(). Without this patch, the sky2 driver can be crashed by doing: # pktgen eth1 & (transmit many packets on eth1) # ethtool -G eth1 tx 510 I am aware you object to storing extra state, but I can't see a way around this. Without remembering that we're restarting, netif_wake_queue() is called in the ISR from sky2_tx_complete(), and netif_tx_lock() is used in sky2_tx_done().

2009-08-03cfg80211: fix regression on beacon world roaming featureLuis R. Rodriguez
A regression was added through patch a4ed90d6: "cfg80211: respect API on orig_flags on channel for beacon hint" We did indeed respect _orig flags but the intention was not clearly stated in the commit log. This patch fixes firmware issues picked up by iwlwifi when we lift passive scan of beaconing restrictions on channels its EEPROM has been configured to always enable. By doing so though we also disallowed beacon hints on devices registering their wiphy with custom world regulatory domains enabled, this happens to be currently ath5k, ath9k and ar9170. The passive scan and beacon restrictions on those devices would never be lifted even if we did find a beacon and the hardware did support such enhancements when world roaming. Since Johannes indicates iwlwifi firmware cannot be changed to allow beacon hinting we set up a flag now to specifically allow drivers to disable beacon hints for devices which cannot use them. We enable the flag on iwlwifi to disable beacon hints and by default enable it for all other drivers. It should be noted beacon hints lift passive scan flags and beacon restrictions when we receive a beacon from an AP on any 5 GHz non-DFS channels, and channels 12-14 on the 2.4 GHz band. We don't bother with channels 1-11 as those channels are allowed world wide. This should fix world roaming for ath5k, ath9k and ar9170, thereby improving scan time when we receive the first beacon from any AP, and also enabling beaconing operation (AP/IBSS/Mesh) on cards which would otherwise not be allowed to do so. Drivers not using custom regulatory stuff (wiphy_apply_custom_regulatory()) were not affected by this as the orig_flags for the channels would have been cleared upon wiphy registration. I tested this with a world roaming ath5k card. Cc: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: Luis R.

2009-08-02ppp: fix lost fragments in ppp_mp_explode() (resubmit)Ben McKeegan
This patch fixes the corner cases where the sum of MTU of the free channels (adjusted for fragmentation overheads) is less than the MTU of PPP link. There are at least 3 situations where this case might arise: - some of the channels are busy - the multilink session is running in a degraded state (i.e. with less than its full complement of active channels) - by design, where multilink protocol is being used to artificially increase the effective link MTU of a single link. Without this patch, at most 1 fragment is ever sent per free channel for a given PPP frame and any remaining part of the PPP frame that does not fit into those fragments is silently discarded. This patch restores the original behaviour which was broken by commit 9c705260feea6ae329bc6b6d5f6d2ef0227eda0a 'ppp:ppp_mp_explode() redesign'. Once all 'free' channels have been given a fragment, an additional fragment is queued to each available channel in turn, as many times as necessary, until the entire PPP frame has been consumed.

The RSC completions in hardware don't complete before the next ITR event tries to fire, so the ITR timer never gets re-armed.

2009-07-29mac80211: fix suspendJohannes Berg
Jan reported that his b43-based laptop hangs during suspend. The problem turned out to be mac80211 asking the driver to stop the hardware before removing interfaces, and interface removal caused b43 to touch the hardware (while down, which causes the hang). This patch fixes mac80211 to do reorder these operations to have them in the correct order -- first remove interfaces and then stop the hardware. Some more code is necessary to be able to do so in a race-free manner, in particular it is necessary to not process frames received during quiescing.

2009-07-29libertas: Read buffer overflowRoel Kluin
Several arrays were read before checking whether the index was within bounds. ARRAY_SIZE() should be used to determine the size of arrays. rates->rates has an arraysize of 1, so calling get_common_rates() with a rates_size of MAX_RATES (14) was causing reads out of bounds. tmp_size can increment at most to (ARRAY_SIZE(lbs_bg_rates) - 1) * (*rates_size - 1), so that should be the number of elements of tmp[]. A goto can be eliminated: ret was already set upon its declaration. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
