2017-01-12ath9k: ar9003_mac: kill off ACCESS_ONCE()Mark Rutland1-46/+46
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't currently harmful. However, for some new features (e.g. KTSAN / Kernel Thread Sanitizer), it is necessary to instrument reads and writes separately, which is not possible with ACCESS_ONCE(). This distinction is critical to correct operation. It's possible to transform the bulk of kernel code using the Coccinelle script below. However, for some files (including the ath9k ar9003 mac driver), this mangles the formatting. As a preparatory step, this patch converts the driver to use {READ,WRITE}_ONCE() without said mangling. ---- virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: ath9k-devel@qca.qualcomm.com Cc: Kalle Valo <kvalo@codeaurora.org> Cc: linux-wireless@vger.kernel.org Cc: ath9k-devel@lists.ath9k.org Cc: netdev@vger.kernel.org Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2017-01-11ipvlan: improvise dev_id generation logic in IPvlanMahesh Bandewar2-1/+13
The patch 009146d117b ("ipvlan: assign unique dev-id for each slave device.") used ida_simple_get() to generate dev_ids assigned to the slave devices. However (Eric has pointed out that) there is a shortcoming with that approach as it always uses the first available ID. This becomes a problem when a slave gets deleted and a new slave gets added. The ID gets reassigned causing the new slave to get the same link-local address. This side-effect is undesirable. This patch adds a per-port variable that keeps track of the IDs assigned and used as the stat-base for the IDR api. This base will be wrapped around when it reaches the MAX (0xFFFE) value possibly on a busy system where slaves are added and deleted routinely.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5 4K UAR The following series of patches optimizes the usage of the UAR area which is contained within the BAR 0-1. Previous versions of the firmware and the driver assumed each system page contains a single UAR. This patch set will query the firmware for a new capability that if published, means that the firmware can support UARs of fixed 4K regardless of system page size. In the case of powerpc, where page size equals 64KB, this means we can utilize 16 UARs per system page. Since user space processes by default consume eight UARs per context this means that with this change a process will need a single system page to fulfill that requirement and in fact make use of more UARs which is better in terms of performance. In addition to optimizing user-space processes, we introduce an allocator that can be used by kernel consumers to allocate blue flame registers (which are areas within a UAR that are used to write doorbells). This provides further optimization on using the UAR area since the Ethernet driver makes use of a single blue flame register per system page and now it will use two blue flame registers per 4K. The series also makes changes to naming conventions and now the terms used in the driver code match the terms used in the PRM (programmers reference manual). Thus, what used to be called UUAR (micro UAR) is now called BFREG (blue flame register). In order to support compatibility between different versions of library/driver/firmware, the library has now means to notify the kernel driver that it supports the new scheme and the kernel can notify the library if it supports this extension. So mixed versions of libraries can run concurrently without any issues. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-01-09sh_eth: add generic wake-on-lan support via magic packetNiklas Söderlund2-8/+109
Add generic functionality to support Wake-on-LAN using MagicPacket which are supported by at least a few versions of sh_eth. Only add functionality for WoL, no specific sh_eth versions are marked to support WoL yet. WoL is enabled in the suspend callback by setting MagicPacket detection and disabling all interrupts expect MagicPacket. In the resume path the driver needs to reset the hardware to rearm the WoL logic, this prevents the driver from simply restoring the registers and to take advantage of that sh_eth was not suspended to reduce resume time. To reset the hardware the driver closes and reopens the device just like it would do in a normal suspend/resume scenario without WoL enabled, but it both closes and opens the device in the resume callback since the device needs to be open for WoL to work. One quirk needed for WoL is that the module clock needs to be prevented from being switched off by Runtime PM. To keep the clock alive the suspend callback need to call clk_enable() directly to increase the usage count of the clock. Then when Runtime PM decreases the clock usage count it won't reach 0 and be switched off. Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Signed-off-by: David S.

2017-01-09phy state machine: failsafe leave invalid RUNNING stateZefir Kurtisi1-0/+9
While in RUNNING state, phy_state_machine() checks for link changes by comparing phydev->link before and after calling phy_read_status(). This works as long as it is guaranteed that phydev->link is never changed outside the phy_state_machine(). If in some setups this happens, it causes the state machine to miss a link loss and remain RUNNING despite phydev->link being 0. This has been observed running a dsa setup with a process continuously polling the link states over ethtool each second (SNMPD RFC-1213 agent). Disconnecting the link on a phy followed by a ETHTOOL_GSET causes dsa_slave_get_settings() / dsa_slave_get_link_ksettings() to call phy_read_status() and with that modify the link status - and with that bricking the phy state machine. This patch adds a fail-safe check while in RUNNING, which causes to move to CHANGELINK when the link is gone and we are still RUNNING.

This patch moves stmmac_clk, pclk, clk_ptp_ref and stmmac_rst to the plat_stmmacenet_data structure. It also moves these platform variables initialization to stmmac_platform. This was done for two reasons: a) If PCI is used, platform related code is being executed in stmmac_main resulting in warnings that have no sense and conceptually was not right b) stmmac as a synopsys reference ethernet driver stack will be hosting more and more drivers to its structure like synopsys/dwc_eth_qos.c. These drivers have their own DT bindings that are not compatible with stmmac's. One of the most important are the clock names, and so they need to be parsed in the glue logic and initialized there, and that is the main reason why the clocks were passed to the platform structure.

Add fields to structs to convey to kernel an indication whether the library supports multi UARs per page and return to the library the size of a UAR based on the queried value.

2017-01-09IB/mlx5: Allow future extension of libmlx5 input dataEli Cohen4-153/+198
Current check requests that new fields in struct mlx5_ib_alloc_ucontext_req_v2 that are not known to the driver be zero. This was introduced so new libraries passing additional information to the kernel through struct mlx5_ib_alloc_ucontext_req_v2 will be notified by old kernels that do not support their request by failing the operation. This schecme is problematic since it requires libmlx5 to issue the requests with descending input size for struct mlx5_ib_alloc_ucontext_req_v2. To avoid this, we require that new features that will obey the following rules: If the feature requires one or more fields in the response and the at least one of the fields can be encoded such that a zero value means the kernel ignored the request then this field will provide the indication to the library. If no response is required or if zero is a valid response, a new field should be added that indicates to the library whether its request was processed.

2017-01-09IB/mlx5: Use blue flame register allocator in mlx5_ibEli Cohen7-198/+54
Make use of the blue flame registers allocator at mlx5_ib. Since blue flame was not really supported we remove all the code that is related to blue flame and we let all consumers to use the same blue flame register. Once blue flame is supported we will add the code. As part of this patch we also move the definition of struct mlx5_bf to mlx5_ib.h as it is only used by mlx5_ib.

2017-01-09net/mlx5: Add interface to get reference to a UAREli Cohen3-13/+55
A reference to a UAR is required to generate CQ or EQ doorbells. Since CQ or EQ doorbells can all be generated using the same UAR area without any effect on performance, we are just getting a reference to any available UAR, If one is not available we allocate it but we don't waste the blue flame registers it can provide and we will use them for subsequent allocations. We get a reference to such UAR and put in mlx5_priv so any kernel consumer can make use of it.
