2017-01-13NFSv4: Fix client recovery when server reboots multiple timesTrond Myklebust1-1/+0
If the server reboots multiple times, the client should rely on the server to tell it that it cannot reclaim state as per section 9.6.3.4 in RFC7530 and section 8.4.2.1 in RFC5661. Currently, the client is being to conservative, and is assuming that if the server reboots while state recovery is in progress, then it must ignore state that was not recovered before the reboot.

The __bcm_sysport_tx_reclaim() function is used to reclaim transmit resources in different places within the driver. Most of them should not affect the state of the transit flow control. Introduce bcm_sysport_tx_clean() which cleans the ring, but does not re-enable flow control towards the networking stack, and make bcm_sysport_tx_reclaim() do the actual transmit queue flow control.

2017-01-13mac80211: prevent skb/txq mismatchMichal Kazior1-10/+7
Station structure is considered as not uploaded (to driver) until drv_sta_state() finishes. This call is however done after the structure is attached to mac80211 internal lists and hashes. This means mac80211 can lookup (and use) station structure before it is uploaded to a driver. If this happens (structure exists, but sta->uploaded is false) fast_tx path can still be taken. Deep in the fastpath call the sta->uploaded is checked against to derive "pubsta" argument for ieee80211_get_txq(). If sta->uploaded is false (and sta is actually non-NULL) ieee80211_get_txq() effectively downgraded to vif->txq. At first glance this may look innocent but coerces mac80211 into a state that is almost guaranteed (codel may drop offending skb) to crash because a station-oriented skb gets queued up on vif-oriented txq. The ieee80211_tx_dequeue() ends up looking at info->control.flags and tries to use txq->sta which in the fail case is NULL. It's probably pointless to pretend one can downgrade skb from sta-txq to vif-txq. Since downgrading unicast traffic to vif->txq must not be done there's no txq to put a frame on if sta->uploaded is false. Therefore the code is made to fall back to regular tx() op path if the described condition is hit. Only drivers using wake_tx_queue were affected.

2017-01-13cfg80211: Add support for randomizing TA of Public Action framesvamsi krishna2-2/+25
Add support to use a random local address (Address 2 = TA in transmit and the same address in receive functionality) for Public Action frames in order to improve privacy of WLAN clients. Applications fill the random transmit address in the frame buffer in the NL80211_CMD_FRAME command. This can be used only with the drivers that indicate support for random local address by setting the new NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA and/or NL80211_EXT_FEATURE_MGMT_TX_RANDOM_TA_CONNECTED in ext_features. The driver needs to configure receive behavior to accept frames to the specified random address during the time the frame exchange is pending and such frames need to be acknowledged similarly to frames sent to the local permanent address when this random address functionality is not used.

2017-01-13ipmr: improve hash scalabilityNikolay Aleksandrov2-130/+182
Recently we started using ipmr with thousands of entries and easily hit soft lockups on smaller devices. The reason is that the hash function uses the high order bits from the src and dst, but those don't change in many common cases, also the hash table is only 64 elements so with thousands it doesn't scale at all. This patch migrates the hash table to rhashtable, and in particular the rhl interface which allows for duplicate elements to be chained because of the MFC_PROXY support (*,G; *,*,oif cases) which allows for multiple duplicate entries to be added with different interfaces (IMO wrong, but it's been in for a long time). And here are some results from tests I've run in a VM: mr_table size (default, allocated for all namespaces): Before After 49304 bytes 2400 bytes Add 65000 routes (the diff is much larger on smaller devices): Before After 1m42s 58s Forwarding 256 byte packets with 65000 routes (test done in a VM): Before After 3 Mbps / ~1465 pps 122 Mbps / ~59000 pps As a bonus we no longer see the soft lockups on smaller devices which showed up even with 2000 entries before.

In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes svc_rdma_put_frmr() which in turn tries to unmap the same sg list through ib_dma_unmap_sg() again. This second unmap is invalid and could lead to problems when the iova being unmapped is subsequently reused. Remove the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr() handle it.

2017-01-12net: ipv4: fix table id in getroute responseDavid Ahern1-1/+1
rtm_table is an 8-bit field while table ids are allowed up to u32. Commit 709772e6e065 ("net: Fix routing tables with id > 255 for legacy software") added the preference to set rtm_table in dumps to RT_TABLE_COMPAT if the table id is > 255. The table id returned on get route requests should do the same.

Commit 6ffe1c4cd0a7 ("net: qcom/emac: fix of_node and phydev leaks") fixed the problem with reference leaks on phydev, but the fix is device-tree specific. When the driver unloads, the reference is dropped only on DT systems. Instead, it's cleaner if up grab an reference on ACPI systems. When the driver unloads, we can drop the reference without having to check whether we're on a DT system.

On AMD's SB800 and upwards, the SMBus is shared with the Integrated Micro Controller (IMC). The platform provides a hardware semaphore to avoid race conditions among them. (Check page 288 of the SB800-Series Southbridges Register Reference Guide http://support.amd.com/TechDocs/45482.pdf) Without this patch, many access to the SMBus end with an invalid transaction or even with the bus stalled.

2017-01-12i2c: do not enable fall back to Host Notify by defaultDmitry Torokhov3-9/+17
Falling back unconditionally to HostNotify as primary client's interrupt breaks some drivers which alter their functionality depending on whether interrupt is present or not, so let's introduce a board flag telling I2C core explicitly if we want wired interrupt or HostNotify-based one: I2C_CLIENT_HOST_NOTIFY. For DT-based systems we introduce "host-notify" property that we convert to I2C_CLIENT_HOST_NOTIFY board flag.
