2015-03-13brcmfmac: Fix oops when SDIO device is removed.Hante Meuleman
On removal of SDIO card both functions of card will be getting a remove call. When the first is hanging in ctrl frame xmit then the second will cause oops. This patch fixes the xmit ctrl handling in case of serious errors and also limits the handling for remove to function 1 only.

2015-03-13ath5k: fix reset raceSergey Ryazanov
To prepare for reset ath5k should finish all asynchronous tasks. At first, it disables the interrupt generation, then it waits for the interrupt handler and tasklets completion, and then proceeds to the HW configuration update. But it does not consider that the interrupt handler or tasklet re-enables the interrupt generation. And we fall in a situation when ath5k assumes that interrupts are disabled, but it is not. This can lead to different consequences, such as reception of the frame, when we do not expect it. Under certain circumstances, this can lead to the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c Fix this issue by adding a new status flag, which forbids to re-enable the interrupt generation until the HW configuration is completed.

2015-03-13ath5k: channel change fixSergey Ryazanov
ath5k updates the channel pointer and after that it stops the Rx logic and apply channel to HW. In case of channel switch, such sequence creates a small window when a frame, which is received on the old channel is considered as a frame received on the new one. The most notable consequence of this situation occurs during the switch from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received with CCK rate, e.g. beacon received at the 1mbps, causes the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c The easiest way to reproduce this warning is to run scan with dualband NIC in noisy environments, when the channel 11 runs multiple APs. In my tests if the APs num >= 12, the warning appears in the first few seconds of scanning. In order to fix this, the Rx disable code moved to a higher level and placed before the channel pointer update. This is also makes the code a bit more symmetrical, since we disable and enable the Rx in the same function. In fact, at the pointer update time new frames should not appear, because interrupt generation at this point should already be disabled. The next patch should address this issue.

2015-03-12net/macb: Only adjust tx_clk on link changeJaeden Amero
The PHY state machine (in drivers/net/phy/phy.c) will unconditionally call phydev->adjust_link (macb_handle_link_change) when polling in the PHY_CHANGELINK state. As currently written, macb always ends up requesting a new tx_clk frequency in macb_handle_link_change. It is a waste of time to request a new tx_clk frequency if the link state hasn't changed, as the tx_clk will already be configured properly. Let's only request a new tx_clk clock frequency when necessary.

2015-03-12rhashtable: kill ht->shift atomic operationsDaniel Borkmann
Commit c0c09bfdc415 ("rhashtable: avoid unnecessary wakeup for worker queue") changed ht->shift to be atomic, which is actually unnecessary. Instead of leaving the current shift in the core rhashtable structure, it can be cached inside the individual bucket tables. There, it will only be initialized once during a new table allocation in the shrink/expansion slow path, and from then onward it stays immutable for the rest of the bucket table liftime. That allows shift to be non-atomic. The patch also moves hash_rnd management into the table setup. The rhashtable structure now consumes 3 instead of 4 cachelines.

2015-03-12cls_bpf: do eBPF invocation under non-bh RCU lock variant for mapsDaniel Borkmann
Currently, it is possible in cls_bpf to access eBPF maps only under rcu_read_lock_bh() variants: while on ingress side, that is, handle_ing(), the classifier would be called from __netif_receive_skb_core() under rcu_read_lock(); on egress side, however, it's rcu_read_lock_bh() via __dev_queue_xmit(). This rcu/rcu_bh mix doesn't work together with eBPF maps as they require soley to be called under rcu_read_lock(). eBPF maps could also be shared among various other eBPF programs (possibly even with other eBPF program types, f.e. tracing) and user space processes, so any context is assumed. Therefore, a possible fix for cls_bpf is to wrap/nest eBPF program invocation under non-bh RCU lock variant.

Miller <davem@davemloft.net>
2015-03-12fib_trie: Provide a deterministic order for fib_alias w/ tables mergedAlexander Duyck
This change makes it so that we should always have a deterministic ordering for the main and local aliases within the merged table when two leaves overlap. So for example if we have a leaf with a key of 192.168.254.0. If we previously added two aliases with a prefix length of 24 from both local and main the first entry would be first and the second would be second. When I was coding this I had added a WARN_ON should such a situation occur as I wasn't sure how likely it would be. However this WARN_ON has been triggered so this is something that should be addressed. With this patch the ordering of the aliases is as follows. First they are sorted on prefix length, then on their table ID, then tos, and finally priority. This way what we end up doing is essentially interleaving the two tables on what used to be leaf_info structure boundaries.

2015-03-12ebpf: verifier: check that call reg with ARG_ANYTHING is initializedDaniel Borkmann
I noticed that a helper function with argument type ARG_ANYTHING does not need to have an initialized value (register). This can worst case lead to unintented stack memory leakage in future helper functions if they are not carefully designed, or unintended application behaviour in case the application developer was not careful enough to match a correct helper function signature in the API. The underlying issue is that ARG_ANYTHING should actually be split into two different semantics: 1) ARG_DONTCARE for function arguments that the helper function does not care about (in other words: the default for unused function arguments), and 2) ARG_ANYTHING that is an argument actually being used by a helper function and *guaranteed* to be an initialized register. The current risk is low: ARG_ANYTHING is only used for the 'flags' argument (r4) in bpf_map_update_elem() that internally does strict checking.

Aka less work and safer for the same effect. I kill hold_net and release_net first as are they are haven't been used since 2008 and are noise at the points where write_pnet and read_pnet are used.

Instead it is possible to say: > typedef struct { > #ifdef CONFIG_NET_NS > struct net *net; > #endif > } possible_net_t; And then in a header say: > possible_net_t net; Which is cleaner and easier to use and easier to test, as the possible_net_t is always there no matter what the compile options. Further this allows read_pnet and write_pnet to be functions in all cases which is better at catching typos. This change adds possible_net_t, updates the definitions of read_pnet and write_pnet, updates optional struct net * variables that write_pnet uses on to have the type possible_net_t, and finally fixes up the b0rked users of read_pnet and write_pnet.

The newer devices will enable a new register for this (DEVICE_SET_NMI_8000B_REG), but the interrupt handler isn't wired yet. Keep the old register for now. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: mvm: freeze the non-shared queues when a station goes to sleepEmmanuel Grumbach
When a station goes to sleep, we can't transmit any frame to it. This means that until that station will wake up, a queue that is dedicated to this station won't progress at all. Take this into account when monitoring stuck queues and don't account for the time the station was asleep. This allows to mask false positives where the queues are stuck not because of a bug, but because of the station being asleep. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: pcie: allow the op_mode to freeze the stuck queue timerEmmanuel Grumbach
This allows the op_mode to let the transport know that a queue is currently frozen and that its timer should be stopped. When the queue is unfrozen, its timer should be set to expire after the remainder of the timeout has elapsed. This can be used when stations go to sleep. When a station goes to sleep, the op_mode can freeze the timer so that the queue will never be considered as stuck. When the station wakes up, the queue will be unfrozen. This is meant to avoid false positives that would happen if a buggy station goes to sleep for a very long time. In case we have a dedicated queue for this station (BA agreement) and it goes to sleep for a very long time, the queue would rightfully be stopped during all that time. In this case, the stuck queue timer could fire and that would be a false positive. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

The Tx statistics weren't updated when using fixed rate for debugging. Fix this as Tx statistics are useful in this use case. Signed-off-by: Eyal Shapira <eyalx.shapira@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: mvm: don't init MCC during CT-killArik Nemtsov
RTNL is not taken during CT-kill so regulatory APIs cannot be invoked. That's fine, since the HW is only brought up to check the temperature during CT-kill. We don't expect Tx or scanning.

When using IBSS, it's easily possible to exhaust the number of available stations in the driver, so don't warn on it. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2015-03-12iwlwifi: trans: Take ownership on secure machine before FW loadEran Harary
When we load the firmware for the 8000 B step device, it'll verify its signature. In the current version of the hardware, there can be a race between the WiFi firmware being loaded and the Bluetooth firmware being loaded. Check that WiFi is authenticated, if not, take ownership on the authentication machine to make sure that the WiFi firmware will be authenticated.
