2016-06-05bnx2x: allow adding VLANs while interface is downMichal Schmidt1-89/+62
Since implementing VLAN filtering in commit 05cc5a39ddb74 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load.

2016-06-03net-next: mediatek: properly handle RGMII modesJohn Crispin1-0/+3
If an external Gigabit PHY is connected to either of the MACs we need to be able to tell the PHY to use a delay. Not doing so will result in heavy packet loss and/or data corruption when using PHYs such as the IC+ IP1001. We tell the PHY which MII delay mode to use via the devictree. The ethernet driver needs to be adapted to handle all 3 rgmii-*id modes in the same way as normal rgmii when setting up the MAC.

2016-06-03net-next: mediatek: add fixed-phy supportJohn Crispin1-0/+3
The MT7623 SoC has a builtin gigabit switch. If we want to use it, GMAC1 needs to be configured using a fixed link speed and flow control settings. The easiest way to do this is to used the fixed-phy driver, allowing us to reuse the existing mdio polling code to setup the MAC.

The rx-usecs shouldn't be changed while interface down/up. Currently, for instance, if it's set to 100us, after interface down/up it's 500us.

2016-06-02stmmac: do not sleep in atomic context for mdio_resetVincent Palatin1-2/+4
stmmac_mdio_reset() has been updated to use msleep rather udelay (as some PHY requires a one second delay there). It called from stmmac_resume() within the spin_lock_irqsave block atomic context triggering 'scheduling while atomic'. The stmmac_priv lock usage is not fully documented, but it seems to protect the access to the MAC registers / DMA structures rather than the MDIO bus or the PHY (which have separate locking), so we can push the spin_lock after the stmmac_mdio_reset call.

gcc warns about qed_fill_link possibly accessing uninitialized data: drivers/net/ethernet/qlogic/qed/qed_main.c: In function 'qed_fill_link': drivers/net/ethernet/qlogic/qed/qed_main.c:1170:35: error: 'link_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized] While this warning is only about the specific case of CONFIG_QED_SRIOV being disabled but the function getting called for a VF (which should never happen), another possibility is that qed_mcp_get_*() fails without returning data. This rearranges the code so we bail out in either of the two cases and print a warning instead of accessing the uninitialized data. The qed_link_output structure remains untouched in this case, but all callers first call memset() on it, so at least we are not leaking stack data then. As discussed, we also use a compile-time check to ensure we never use any of the VF code if CONFIG_QED_SRIOV is disabled, and the PCI device table is updated to no longer bind to virtual functions in that configuration.

Make sure to re-read the direction setting if we have the .get_direction() callback enabled for the chip. Else we get problems like this: iio iio:device2: interrupts on the rising edge gpio gpiochip2: (8012e080.gpio): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ gpio gpiochip2: (8012e080.gpio): unable to lock HW IRQ 0 for IRQ genirq: Failed to request resources for l3g4200d-trigger (irq 111) on irqchip nmk1-32-63 iio iio:device2: failed to request trigger IRQ. st-gyro-i2c: probe of 2-0068 failed with error -22 Fixes: 72d320006177 ("gpio: set up initial state from .get_direction()") Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-05-30gpio: lpc32xx: disable broken to_irq supportSylvain Lemieux1-47/+1
The "to_irq" functionality is broken inside this driver since commit 76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler"). The addition of the new lpc32xx irqchip driver in 4.7, fixed the lpc32xx platform interrupt issue. When switching to the new lpc32xx irqchip driver, a warning appear in the lpc32xx gpio driver: warning: "NR_IRQS" redefined. To remove this warning (temporary solution), this patch disables the broken "to_irq" mapping functionality support.

2016-05-29net: nps_enet: Disable interrupts before napi rescheduleElad Kanfi1-1/+3
Since NAPI works by shutting down event interrupts when theres work and turning them on when theres none, the net driver must make sure that interrupts are disabled when it reschedules polling. By calling napi_reschedule, the driver switches to polling mode, therefor there should be no interrupt interference. Any received packets will be handled in nps_enet_poll by polling the HW indication of received packet until all packets are handled.

Pull string hash improvements from George Spelvin: "This series does several related things: - Makes the dcache hash (fs/namei.c) useful for general kernel use. (Thanks to Bruce for noticing the zero-length corner case) - Converts the string hashes in <linux/sunrpc/svcauth.h> to use the above. - Avoids 64-bit multiplies in hash_64() on 32-bit platforms. Two 32-bit multiplies will do well enough. - Rids the world of the bad hash multipliers in hash_32. This finishes the job started in commit 689de1d6ca95 ("Minimal fix-up of bad hashing behavior of hash_64()") The vast majority of Linux architectures have hardware support for 32x32-bit multiply and so derive no benefit from "simplified" multipliers. The few processors that do not (68000, h8/300 and some models of Microblaze) have arch-specific implementations added. Those patches are last in the series. - Overhauls the dcache hash mixing. The patch in commit 0fed3ac866ea ("namei: Improve hash mixing if CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion. Replaced with a much more careful design that's simultaneously faster and better. (My own invention, as there was noting suitable in the literature I could find. Comments welcome!) - Modify the hash_name() loop to skip the initial HASH_MIX(). This would let us salt the hash if we ever wanted to. - Sort out partial_name_hash(). The hash function is declared as using a long state, even though it's truncated to 32 bits at the end and the extra internal state contributes nothing to the result. And some callers do odd things: - fs/hfs/string.c only allocates 32 bits of state - fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes - Modify bytemask_from_count to handle inputs of 1..sizeof(long) rather than 0..sizeof(long)-1. This would simplify users other than full_name_hash" Special thanks to Bruce Fields for testing and finding bugs in v1. (I learned some humbling lessons about "obviously correct" code.) On the arch-specific front, the m68k assembly has been tested in a standalone test harness, I've been in contact with the Microblaze maintainers who mostly don't care, as the hardware multiplier is never omitted in real-world applications, and I haven't heard anything from the H8/300 world" * 'hash' of git://ftp.sciencehorizons.net/linux: h8300: Add <asm/hash.h> microblaze: Add <asm/hash.h> m68k: Add <asm/hash.h> <linux/hash.h>: Add support for architecture-specific functions fs/namei.c: Improve dcache hash function Eliminate bad hash multipliers from hash_32() and hash_64() Change hash_64() return value to 32 bits <linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string() fs/namei.c: Add hashlen_string() function Pull out string hash to <linux/stringhash.h>
2016-05-28Eliminate bad hash multipliers from hash_32() and hash_64()George Spelvin1-0/+2
The "simplified" prime multipliers made very bad hash functions, so get rid of them. This completes the work of 689de1d6ca. To avoid the inefficiency which was the motivation for the "simplified" multipliers, hash_64() on 32-bit systems is changed to use a different algorithm. It makes two calls to hash_32() instead. drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32 for some horrible reason, so it inherits a copy of the old definition.

It looks large, but only in one sense. I'll get to that in a minute. The list of changes here breaks down as follows: - Dynamic counter infrastructure in the IB drivers This is a sysfs based code to allow free form access to the hardware counters RDMA devices might support so drivers don't need to code this up repeatedly themselves - SendOnlyFullMember multicast support - IB router support - A couple misc fixes - The big item on the list: hfi1 driver updates, plus moving the hfi1 driver out of staging There was a group of 15 patches in the hfi1 list that I thought I had in the first pull request but they weren't. So that added to the length of the hfi1 section here. As far as these go, everything but the hfi1 is pretty straight forward. The hfi1 is, if you recall, the driver that Al had complaints about how it used the write/writev interfaces in an overloaded fashion. The write portion of their interface behaved like the write handler in the IB stack proper and did bi-directional communications. The writev interface, on the other hand, only accepts SDMA request structures. The completions for those structures are sent back via an entirely different event mechanism. With the security patch, we put security checks on the write interface, however, we also knew they would be going away soon. Now, we've converted the write handler in the hfi1 driver to use ioctls from the IB reserved magic area for its bidirectional communications. With that change, Intel has addressed all of the items originally on their TODO when they went into staging (as well as many items added to the list later). As such, I moved them out, and since they were the last item in the staging/rdma directory, and I don't have immediate plans to use the staging area again, I removed the staging/rdma area. Because of the move out of staging, as well as a series of 5 patches in the hfi1 driver that removed code people thought should be done in a different way and was optional to begin with (a snoop debug interface, an eeprom driver for an eeprom connected directory to their hfi1 chip and not via an i2c bus, and a few other things like that), the line count, especially the removal count, is high" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (56 commits) staging/rdma: Remove the entire rdma subdirectory of staging IB/core: Make device counter infrastructure dynamic IB/hfi1: Fix pio map initialization IB/hfi1: Correct 8051 link parameter settings IB/hfi1: Update pkey table properly after link down or FM start IB/rdamvt: Fix rdmavt s_ack_queue sizing IB/rdmavt: Max atomic value should be a u8 IB/hfi1: Fix hard lockup due to not using save/restore spin lock IB/hfi1: Add tracing support for send with invalidate opcode IB/hfi1, qib: Add ieth to the packet header definitions IB/hfi1: Move driver out of staging IB/hfi1: Do not free hfi1 cdev parent structure early IB/hfi1: Add trace message in user IOCTL handling IB/hfi1: Remove write(), use ioctl() for user cmds IB/hfi1: Add ioctl() interface for user commands IB/hfi1: Remove unused user command IB/hfi1: Remove snoop/diag interface IB/hfi1: Remove EPROM functionality from data device IB/hfi1: Remove UI char device IB/hfi1: Remove multiple device cdev ...
