  • 9f7f78b47   mac802154: Keep track of the channel when changed ... Browse Code »

    Two sections checked whether the current channel != the new channel
    without ever setting the current channel variables.

    1. net/mac802154/tx.c: Prevent set_channel() from getting called every
    time a packet is sent.

    2. net/mac802154/mib.c: Lock (pib_lock) accesses to current_channel and
    current_page and make sure they are updated when the channel has been
    changed.

  • e937f583e   mac802154: Increase tx_buffer_len ... Browse Code »

    Increase the buffer length from 10 to 300 packets. Consider that traffic on
    mac802154 devices will often be 6LoWPAN, and a full-length (1280 octet)
    IPv6 packet will fragment into 15 6LoWPAN fragments (because the MTU of
    IEEE 802.15.4 is 127). A 300-packet queue is really 20 full-length IPv6
    packets.

    With a queue length of 10, an entire IPv6 packet was unable to get queued
    at one time, causing fragments to be dropped, and making reassembly
    impossible.

  • b5992fe96   mac802154: Use netif flow control ... Browse Code »

    Use netif_stop_queue() and netif_wake_queue() to control the flow of
    packets to mac802154 devices. Since many IEEE 802.15.4 devices have no
    output buffer, and since the mac802154 xmit() function is designed to
    block, netif_stop_queue() is called after each packet.

  • 7dd43d356   mac802154: Do not try to resend failed packets ... Browse Code »

    When ops->xmit() fails, drop the packet. Devices which support hardware
    ack and retry (which include all devices currently supported by mainline),
    will automatically retry sending the packet (in the hardware) up to 3
    times, per the 802.15.4 spec. There is no need, and it is incorrect to
    try to do it in mac802154.

  • 06991c28f   Merge tag 'driver-core-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core ... Browse Code »

    Pull driver core patches from Greg Kroah-Hartman:
    "Here is the big driver core merge for 3.9-rc1

    There are two major series here, both of which touch lots of drivers
    all over the kernel, and will cause you some merge conflicts:

    - add a new function called devm_ioremap_resource() to properly be
    able to check return values.

    - remove CONFIG_EXPERIMENTAL

    Other than those patches, there's not much here, some minor fixes and
    updates"

    Fix up trivial conflicts

  • e5a2f6e3c   net/mac802154: remove depends on CONFIG_EXPERIMENTAL ... Browse Code »

    The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
    while now and is almost always enabled by default. As agreed during the
    Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

  • 5ff3fec6d   mac802154: fix NOHZ local_softirq_pending 08 warning ... Browse Code »

    When using nanosleep() in an userspace application we get a
    ratelimit warning

    NOHZ: local_softirq_pending 08

    for 10 times.

    This patch replaces netif_rx() with netif_rx_ni() which has
    to be used from process/softirq context.
    The process/softirq context will be called from fakelb driver.

    See linux-kernel commit 481a819 for similar fix.

    mutex_destroy() must be called before wpan_phy_free(), because it puts the last
    reference and frees memory. Catched as overwritten poison in kmalloc-2048.

    Conflicts:
    drivers/net/caif/caif_hsi.c
    drivers/net/usb/qmi_wwan.c

    The qmi_wwan merge was trivial.

    The caif_hsi.c, on the other hand, was not. It's a conflict between
    1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform
    device with ops structure.") in the net-next tree and commit
    39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of
    HIS until open()") in the net tree.

    I did my best with that one and will ask Sjur to check it out.
