2010-03-04gianfar: Fix TX ring processing on SMP machinesAnton Vorontsov
Starting with commit a3bc1f11e9b867a4f49505 ("gianfar: Revive SKB recycling") gianfar driver sooner or later stops transmitting any packets on SMP machines. start_xmit() prepares new skb for transmitting, generally it does three things: 1. sets up all BDs (marks them ready to send), except the first one. 2. stores skb into tx_queue->tx_skbuff so that clean_tx_ring() would cleanup it later. 3. sets up the first BD, i.e. marks it ready. Here is what clean_tx_ring() does: 1. reads skbs from tx_queue->tx_skbuff 2. checks if the *last* BD is ready. If it's still ready [to send] then it it isn't transmitted, so clean_tx_ring() returns. Otherwise it actually cleanups BDs. All is OK. Now, if there is just one BD, code flow: - start_xmit(): stores skb into tx_skbuff. Note that the first BD (which is also the last one) isn't marked as ready, yet. - clean_tx_ring(): sees that skb is not null, *and* its lstatus says that it is NOT ready (like if BD was sent), so it cleans it up (bad!) - start_xmit(): marks BD as ready [to send], but it's too late. We can fix this simply by reordering lstatus/tx_skbuff writes.

2010-03-04r8169: use correct barrier between cacheable and non-cacheable memoryDavid Dillow
r8169 needs certain writes to be visible to other CPUs or the NIC before touching the hardware, but was using smp_wmb() which is only required to order cacheable memory access. Switch to wmb() which is required to order both cacheable and non-cacheable memory. Noticed by Catalin Marinas and Paul Mackerras.

There is nothing stopping a client from trying to send such a message however, and if that happens, we attempt to dereference tipc_net.zones while the pointer is still NULL, and explode. The fix is pretty straightforward. Since these oopses all arise from the dereference of global pointers prior to their assignment to allocated values, and since these allocations are small (about 2k total), lets convert these pointers to static arrays of the appropriate size. All the accesses to these bits consider 0/NULL to be a non match when searching, so all the lookups still work properly, and there is no longer a chance of a bad dererence anywhere. As a bonus, this lets us eliminate the setup/teardown routines for those pointers, and elimnates the need to preform any locking around them to prevent access while their being allocated/freed. I've updated the tipc_net structure to behave this way to fix the exact reported problem, and also fixed up the tipc_bearers and media_list arrays to fix an obvious simmilar problem that arises from issuing tipc-config commands to manipulate bearers/links prior to entering networked mode I've tested this for a few hours by running the sanity tests and stress test with the tipcutils suite, and nothing has fallen over. There have been a few lockdep warnings, but those were there before, and can be addressed later, as they didn't actually result in any deadlock.

2010-03-04gre: fix hard header destination address checkingTimo Teräs
ipgre_header() can be called with zero daddr when the gre device is configured as multipoint tunnel and still has the NOARP flag set (which is typically cleared by the userspace arp daemon). If the NOARP packets are not dropped, ipgre_tunnel_xmit() will take rt->rt_gateway (= NBMA IP) and use that for route look up (and may lead to bogus xfrm acquires). The multicast address check is removed as sending to multicast group should be ok. In fact, if gre device has a multicast address as destination ipgre_header is always called with multicast address.

2010-03-04IPv6: fix race between cleanup and add/delete addressstephen hemminger
This solves a potential race problem during the cleanup process. The issue is that addrconf_ifdown() needs to traverse address list, but then drop lock to call the notifier. The version in -next could get confused if add/delete happened during this window. Original code (2.6.32 and earlier) was okay because all addresses were always deleted.

2010-03-04IPv6: addrconf notify when address is unavailablestephen hemminger
My recent change in net-next to retain permanent addresses caused regression. Device refcount would not go to zero when device was unregistered because left over anycast reference would hold ipv6 dev reference which would hold device references... The correct procedure is to call notify chain when address is no longer available for use. When interface comes back DAD timer will notify back that address is available. Also, link local addresses should be purged when interface is brought down. The address might be changed. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2010-03-03mac80211: Fix HT rate control configurationSujith
Handling HT configuration changes involved setting the channel with the new HT parameters and then issuing a rate_update() notification to the driver. This behavior changed after the off-channel changes. Now, the channel is not updated with the new HT params in enable_ht() - instead, it is now done when the scan work terminates. This results in the driver depending on stale information, defaulting to non-HT mode always. Fix this by passing the new channel type to the driver.

My previous patch 914c8ad2d18b62ad1420f518c0cab0b0b90ab308 incorrectly changed the length check in packet_mc_add to be more strict.

2010-03-02iwlwifi: load firmware asynchronously before mac80211 registrationJohannes Berg
At the wireless summit in Portland we discussed a way of loading firmware asynchronously from ->probe() before registration to mac80211, in order to register with the wireless subsystems with complete information in cases where firmware is required to know parameters. This is not yet the case in iwlwifi, but for some new features we're working on it will be the case since those will only be supported by new firmware images. Hence, to start with, convert iwlwifi to load firmware asynchronously from probe, unbinding the device when firmware loading fails, and only registering with the wireless subsystems after firmware has been loaded successfully. Future patches will hook into this to register the new firmware capabilities, depending on the firmware API version.

2010-03-02mac80211: Fix reassociation processing (within ESS roaming)Jouni Malinen
Commit e1dd33f60ced091114e4aacf141e0d03b88d3e13 changed cfg80211 to allow association commands while in associated state to enable support for roaming within an ESS. However, this was not enough to resolve all cases with mac80211 which needs some additional handling of the reassociation case to clear internal state with the BSS that was in use previously. This patch makes ieee80211_mgd_assoc() accept a valid reassociation command and clean the association state with the previous BSS. This fixes roaming between BSSes in an ESS when using wpa_supplicant with -Dnl80211. Signed-off-by: Jouni Malinen <j@w1.fi> Cc: stable@kernel.org Signed-off-by: John W.

2010-03-01sata_via: Delay on vt6420 when starting ATAPI DMA writeBart Hartgers
When writing a disc on certain lite-on dvd-writers (also rebadged as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends up in the datastream and on the disc, causing silent corruption. Delaying between sending the CDB and starting DMA seems to prevent this. I do not know if there are burners that do not suffer from this, but the patch should be safe for those as well. There are many reports of this issue, but AFAICT no solution was found before.

2010-03-01ata: Detect Delkin Devices compact flashBen Gardner
I have a Delkin Devices compact flash card that isn't being recognized using the SATA/PATA drivers. The card is recognized and works with the deprecated ATA drivers. The error I am seeing is: ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0) I tracked it down to ata_id_is_cfa() in include/linux/ata.h. The Delkin card has id[0] set to 0x844a and id[83] set to 0. This isn't what the kernel expects and is probably incorrect. The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().
