2016-03-02net/mlx5e: Remove wrong poll CQ optimizationTariq Toukan4-22/+1
With the MLX5E_CQ_HAS_CQES optimization flag, the following buggy flow might occur: - Suppose RX is always busy, TX has a single packet every second. - We poll a single TX cqe and clear its flag. - We never arm it again as RX is always busy. - TX CQ flag is never changed, and new TX cqes are not polled. We revert this optimization.

2016-03-02bnx2x: fix sending VF->PF messages on big-endianMichal Schmidt1-6/+0
When a VF is sending a message to the PF, it needs to trigger the PF to tell it the message is ready. The trigger did not work on ppc64. No interrupt appeared in the PF. The bug is due to confusion about the layout of struct trigger_vf_zone. In bnx2x_send_msg2pf() the trigger is written using writeb(), not writel(), so the attempt to define the struct with a reversed layout on big-endian is counter-productive.

2016-03-01phy: micrel: Disable auto negotiation on startupAlexandre Belloni1-0/+11
Disable auto negotiation on init to properly detect an already plugged cable at boot. At boot, when the phy is started, it is in the PHY_UP state. However, if a cable is plugged at boot, because auto negociation is already enabled at the time we get the first interrupt, the phy is already running. But the state machine then switches from PHY_UP to PHY_AN and calls phy_start_aneg(). phy_start_aneg() will not do anything because aneg is already enabled on the phy. It will then wait for a interrupt before going further. This interrupt will never happen unless the cable is unplugged and then replugged. It was working properly before 321beec5047a (net: phy: Use interrupts when available in NOLINK state) because switching to NOLINK meant starting polling the phy, even if IRQ were enabled.

2016-03-01ppp: lock ppp->flags in ppp_read() and ppp_poll()Guillaume Nault1-1/+9
ppp_read() and ppp_poll() can be called concurrently with ppp_ioctl(). In this case, ppp_ioctl() might call ppp_ccp_closed(), which may update ppp->flags while ppp_read() or ppp_poll() is reading it. The update done by ppp_ccp_closed() isn't atomic due to the bit mask operation ('ppp->flags &= ~(SC_CCP_OPEN | SC_CCP_UP)'), so concurrent readers might get transient values. Reading incorrect ppp->flags may disturb the 'ppp->flags & SC_LOOP_TRAFFIC' test in ppp_read() and ppp_poll(), which in turn can lead to improper decision on whether the PPP unit file is ready for reading or not. Since ppp_ccp_closed() is protected by the Rx and Tx locks (with ppp_lock()), taking the Rx lock is enough for ppp_read() and ppp_poll() to guarantee that ppp_ccp_closed() won't update ppp->flags concurrently. The same reasoning applies to ppp->n_channels. The 'n_channels' field can also be written to concurrently by ppp_ioctl() (through ppp_connect_channel() or ppp_disconnect_channel()). These writes aren't atomic (simple increment/decrement), but are protected by both the Rx and Tx locks (like in the ppp->flags case). So holding the Rx lock before reading ppp->n_channels also prevents concurrent writes. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-03-01mac80211: Fix Public Action frame RX in AP modeJouni Malinen1-0/+1
Public Action frames use special rules for how the BSSID field (Address 3) is set. A wildcard BSSID is used in cases where the transmitter and recipient are not members of the same BSS. As such, we need to accept Public Action frames with wildcard BSSID. Commit db8e17324553 ("mac80211: ignore frames between TDLS peers when operating as AP") added a rule that drops Action frames to TDLS-peers based on an Action frame having different DA (Address 1) and BSSID (Address 3) values. This is not correct since it misses the possibility of BSSID being a wildcard BSSID in which case the Address 1 would not necessarily match. Fix this by allowing mac80211 to accept wildcard BSSID in an Action frame when in AP mode.

2016-02-293c59x: mask LAST_FRAG bit from length field in ringNeil Horman1-1/+1
Recently, I fixed a bug in 3c59x: commit 6e144419e4da11a9a4977c8d899d7247d94ca338 Author: Neil Horman <nhorman@tuxdriver.com> Date: Wed Jan 13 12:43:54 2016 -0500 3c59x: fix another page map/single unmap imbalance Which correctly rebalanced dma mapping and unmapping types. Unfortunately it introduced a new bug which causes oopses on older systems. When mapping dma regions, the last entry for a packet in the 3c59x tx ring encodes a LAST_FRAG bit, which is encoded as the high order bit of the buffers length field. When it is unmapped the LAST_FRAG bit is cleared prior to being passed to the unmap function. Unfortunately the commit above fails to do that masking. It was missed in testing because the system on which I tested it had an intel iommu, the driver for which ignores the size field, using only the DMA address as the token to identify the mapping to be released. However, on older systems that rely on swiotlb (or other dma drivers that key off that length field), not masking off that LAST_FRAG high order bit results in parsing a huge size to be release, leading to all sorts of odd corruptions and the like. Fix is easy, just mask the length with 0xFFF. It should really be &(LAST_FRAG-1), but 0xFFF is the style of the file, and I'd like to make this fix minimal and correct before making it prettier. Appies to the net tree cleanly.

There will be a log spam when there is no cable plugged. Please refer to following links. https://bugzilla.kernel.org/show_bug.cgi?id=104351 https://bugzilla.kernel.org/show_bug.cgi?id=107421 This issue is caused by runtime power management. When there is no cable plugged, the driver will be suspend (runtime suspend) by OS and NIC will be put into the D3 state. During this time, if OS call rtl8169_get_stats64() to dump tally counter, because NIC is in D3 state, the register value read by driver will return all 0xff. This will let driver think tally counter flag is not toggled and then sends the warning message "rtl_counters_cond == 1 (loop: 1000, delay: 10)" to kernel log. For fixing this issue, 1.add checking driver's pm runtime status in rtl8169_get_stats64(). 2.dump tally counter before going runtime suspend for counter accuracy in runtime suspend.

2016-02-23tunnel: Clear IPCB(skb)->opt before dst_link_failure calledBernie Harris4-1/+8
IPCB may contain data from previous layers (in the observed case the qdisc layer). In the observed scenario, the data was misinterpreted as ip header options, which later caused the ihl to be set to an invalid value (<5). This resulted in an infinite loop in the mips implementation of ip_fast_csum. This patch clears IPCB(skb)->opt before dst_link_failure can be called for various types of tunnels. This change only applies to encapsulated ipv4 packets. The code introduced in 11c21a30 which clears all of IPCB has been removed to be consistent with these changes, and instead the opt field is cleared unconditionally in ip_tunnel_xmit. The change in ip_tunnel_xmit applies to SIT, GRE, and IPIP tunnels. The relevant vti, l2tp, and pptp functions already contain similar code for clearing the IPCB.

2016-02-23cfg80211: stop critical protocol session upon disconnect eventArend van Spriel1-0/+6
When user-space has started a critical protocol session and a disconnect event occurs, the rdev::crit_prot_nlportid remains set. This caused a subsequent NL80211_CMD_CRIT_PROTO_START to fail (-EBUSY). Fix this by clearing the rdev attribute and call .crit_proto_stop() callback upon disconnect event.

2016-02-23mac80211: minstrel_ht: set default tx aggregation timeout to 0Felix Fietkau1-1/+1
The value 5000 was put here with the addition of the timeout field to ieee80211_start_tx_ba_session. It was originally added in mac80211 to save resources for drivers like iwlwifi, which only supports a limited number of concurrent aggregation sessions. Since iwlwifi does not use minstrel_ht and other drivers don't need this, 0 is a better default - especially since there have been recent reports of aggregation setup related issues reproduced with ath9k. This should improve stability without causing any adverse effects.

2016-02-21net: ethernet: davicom: fix devicetree irq resourceRobert Jarzmik1-17/+17
The dm9000 driver doesn't work in at least one device-tree configuration, spitting an error message on irq resource : [    1.062495] dm9000 8000000.ethernet: insufficient resources [    1.068439] dm9000 8000000.ethernet: not found (-2). [    1.073451] dm9000: probe of 8000000.ethernet failed with error -2 The reason behind is that the interrupt might be provided by a gpio controller, not probed when dm9000 is probed, and needing the probe deferral mechanism to apply. Currently, the interrupt is directly taken from resources. This patch changes this to use the more generic platform_get_irq(), which handles the deferral. Moreover, since commit Fixes: 7085a7401ba5 ("drivers: platform: parse IRQ flags from resources"), the interrupt trigger flags are honored in platform_get_irq(), so remove the needless code in dm9000.

SW data field in descriptor can be used by software to hold private data for the driver. As there are 4 words available for this purpose, use separate macros to place it or retrieve the same to/from descriptors. Also do type cast of data types accordingly.

2016-02-21soc: ti: knav_dma: rename pad in struct knav_dma_desc to sw_dataKaricheri, Muralidharan2-20/+24
Rename the pad to sw_data as per description of this field in the hardware spec(refer sprugr9 from www.ti.com). Latest version of the document is at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1 Host Packet Descriptor describes this field. Define and use a constant for the size of sw_data field similar to other fields in the struct for desc and document the sw_data field in the header. As the sw_data is not touched by hw, it's type can be changed to u32. Rename the helpers to match with the updated dma desc field sw_data.
