2012-04-02sky2: override for PCI legacy power managementstephen hemminger
[ Upstream commit 5676cc7bfe1e388e87843f71daa229610385b41e ] Some BIOS's don't setup power management correctly (what else is new) and don't allow use of PCI Express power control. Add a special exception module parameter to allow working around this issue. Based on slightly different patch by Knut Petersen.

2012-04-02rtlwifi: Convert to asynchronous firmware loadLarry Finger
commit b0302aba812bcc39291cdab9ad7e37008f352a91 upstream. This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2012-04-02usbnet: don't clear urb->dev in tx_completetom.leiming@gmail.com
commit 5d5440a835710d09f0ef18da5000541ec98b537a upstream. URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.

2012-04-02usbnet: increase URB reference count before usb_unlink_urbtom.leiming@gmail.com
commit 0956a8c20b23d429e79ff86d4325583fc06f9eb4 upstream. Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock, but it makes usb_unlink_urb racing with defer_bh, and the URB to being unlinked may be freed before or during calling usb_unlink_urb, so use-after-free problem may be triggerd inside usb_unlink_urb. The patch fixes the use-after-free problem by increasing URB reference count with skb queue lock held before calling usb_unlink_urb, so the URB won't be freed until return from usb_unlink_urb.

2012-04-02iwlwifi: always monitor for stuck queuesJohannes Berg
commit 342bbf3fee2fa9a18147e74b2e3c4229a4564912 upstream. If we only monitor while associated, the following can happen: - we're associated, and the queue stuck check runs, setting the queue "touch" time to X - we disassociate, stopping the monitoring, which leaves the time set to X - almost 2s later, we associate, and enqueue a frame - before the frame is transmitted, we monitor for stuck queues, and find the time set to X, although it is now later than X + 2000ms, so we decide that the queue is stuck and erroneously restart the device It happens more with P2P because there we can go between associated/unassociated frequently.

2012-04-02rtlwifi: rtl8192ce: Fix loss of receive performanceJingjun Wu
commit a9b89e2567c743483e6354f64d7a7e3a8c101e9e upstream. Driver rtl8192ce when used with the RTL8188CE device would start at about 20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the symptoms is that the AP would need to retransmit each packet 4 of 5 times before the driver would acknowledge it. Recovery is possible only by unloading and reloading the driver. This problem was reported at https://bugzilla.redhat.com/show_bug.cgi?id=770207. The problem is due to a missing update of the gain setting.

2012-04-02rtlwifi: rtl8192c: Prevent sleeping from invalid context in rtl8192cuLarry Finger
commit ebecdcc12fed5d3c81853dea61a0a78a5aefab52 upstream. When driver rtl8192cu is used with the debug level set to 3 or greater, the result is "sleeping function called from invalid context" due to an rcu_read_lock() call in the DM refresh routine in driver rtl8192c. This lock is not necessary as the USB driver does not use the struct being protected, thus the lock is set only when a PCI interface is active. This bug is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42775.

2012-03-16bnx2x: fix memory leak in bnx2x_init_firmware()Michal Schmidt
When cycling the interface down and up, bnx2x_init_firmware() knows that the firmware is already loaded, but nevertheless it allocates certain arrays anew (init_data, init_ops, init_ops_offsets, iro_arr). The old arrays are leaked. Fix the leaks by returning early if the firmware was already loaded. Because if the firmware is loaded, so are the arrays.

2012-03-12tun: don't hold network namespace by tun socketsStanislav Kinsbursky
v3: added previously removed sock_put() to the tun_release() callback, because sk_release_kernel() doesn't drop the socket reference. v2: sk_release_kernel() used for socket release. Dummy tun_release() is required for sk_release_kernel() ---> sock_release() ---> sock->ops->release() call. TUN was designed to destroy it's socket on network namesapce shutdown. But this will never happen for persistent device, because it's socket holds network namespace. This patch removes of holding network namespace by TUN socket and replaces it by creating socket in init_net and then changing it's net it to desired one. On shutdown socket is moved back to init_net prior to final put. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-03-12rt2x00: fix random stallsStanislaw Gruszka
Is possible that we stop queue and then do not wake up it again, especially when packets are transmitted fast. That can be easily reproduced with modified tx queue entry_num to some small value e.g. 16. If mac80211 already hold local->queue_stop_reason_lock, then we can wait on that lock in both rt2x00queue_pause_queue() and rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock is possible that __ieee80211_wake_queue() will be performed before __ieee80211_stop_queue(), hence we stop queue and newer wake up it again. Another race condition is possible when between rt2x00queue_threshold() check and rt2x00queue_pause_queue() we will process all pending tx buffers on different cpu. This might happen if for example interrupt will be triggered on cpu performing rt2x00mac_tx(). To prevent race conditions serialize pause/unpause by queue->tx_lock.

If the system is shutdown in this state, any register accesses in rtl_shutdown are dropped on the floor. As the device was programmed by .runtime_suspend() to wake on link changes, it is thus brought back up as soon as the link recovers.

Fix tg3 to use BQL multi queue related netdev interfaces since the device supports multi queue. Signed-off-by: Tom Herbert <therbert@google.com> Reported-by: Christoph Lameter <cl@gentwo.org> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-03-05qla3xxx: ethernet: Fix bogus interrupt state flag.Santosh Nayak
In 'ql_adapter_initialize' the first call for 'spin_unlock_irqrestore()' is with hw_flags = 0, which is as good as 'spin_unlock_irq()' (unconditional interrupt enabling). If this is intended, then for better performance 'spin_unlock_irqrestore()' can be replaced with 'spin_unlock_irq()' and 'spin_lock_irqsave()' can be replaced by 'spin_lock_irq() Signed-off-by: Santosh Nayak <santoshprasadnayak@gmail.com> Signed-off-by: David S.

This was broken by the commit 023ca58f1 "iwlwifi: Move the core suspend function to iwl-agn-lib" where for some reason the code changed while moving, from .len[0] = sizeof(*key_data.rsc_tsc), to .len[0] = sizeof(key_data.rsc_tsc), Cc: stable@kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

As part of the big network driver reorg, each vendor directory defaults to yes, so that older config's can migrate correctly. Looks like this one got missed. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-03-01enic: fix an endian bug in enic_probe()Dan Carpenter
"num_vfs" is a u32 but we only use the high 16 bits and the low 16bits are left as zero. That isn't a problem for little endian systems but it will break on big endian ones. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-03-01pch_gbe: memory corruption calling pch_gbe_validate_option()Dan Carpenter
pch_gbe_validate_option() modifies 32 bits of memory but we pass &hw->phy.autoneg_advertised which only has 16 bits and &hw->mac.fc which only has 8 bits. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-02-29tg3: Fix tg3_get_stats64 for 5700 / 5701 devsMatt Carlson
tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700 and bcm5701 devices. However, functions that call tg3_halt() have already acquired tp->lock. When tg3_get_stats64() is called in tg3_halt(), deadlock will occur. This patch fixes the problem by separating the stat gathering code into a new tg3_get_nstats() function. tg3_get_stats64() is recoded to call this function and take tp->lock. The code that takes tp->lock in tg3_calc_crc_errors() has been removed. Function signatures have been cleaned up too.

2012-02-29carl9170: fix frame delivery if sta is in powersave modeChristian Lamparter
Nicolas Cavallari discovered that carl9170 has some serious problems delivering data to sleeping stations. It turns out that the driver was not honoring two important flags (IEEE80211_TX_CTL_POLL_RESPONSE and IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on frames that should be sent although the receiving station is still in powersave mode.
