sunvnet: only use connected ports when sending

2014-07-29T00:29:53+00:00

The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.

This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

bnx2x: fix crash during TSO tunneling

2014-07-25T06:43:57+00:00

When TSO packet is transmitted additional BD w/o mapping is used
to describe the packed. The BD needs special handling in tx
completion.

net: bcmgenet: correctly pad short packets

2014-07-23T02:59:19+00:00

Packets shorter than ETH_ZLEN were not padded with zeroes, hence leaking
potentially sensitive information. This bug has been present since the
driver got accepted in commit 1c1008c793fa46703a2fee469f4235e1c7984333
("net: bcmgenet: add main driver file").

 1) Null termination fix in dns_resolver got the pointer dereferncing
    wrong, fix from Ben Hutchings.

 2) ip_options_compile() has a benign but real buffer overflow when
    parsing options.  From Eric Dumazet.

 3) Table updates can crash in netfilter's nftables if none of the state
    flags indicate an actual change, from Pablo Neira Ayuso.

 4) Fix race in nf_tables dumping, also from Pablo.

 5) GRE-GRO support broke the forwarding path because the segmentation
    state was not fully initialized in these paths, from Jerry Chu.

 6) sunvnet driver leaks objects and potentially crashes on module
    unload, from Sowmini Varadhan.

 7) We can accidently generate the same handle for several u32
    classifier filters, fix from Cong Wang.

 8) Several edge case bug fixes in fragment handling in xen-netback,
    from Zoltan Kiss.

net/mlx4_en: cq->irq_desc wasn't set in legacy EQ's

Fix a regression introduced by commit 35f6f45 ("net/mlx4_en: Don't use
irq_affinity_notifier to track changes in IRQ affinity map").
When core is started in legacy EQ's (number of IRQ's < rx rings), cq->irq_desc
was NULL.  This caused a kernel crash under heavy traffic - when having more
than rx NAPI budget completions.
Fixed to have it set for both EQ modes.

sunvnet: clean up objects created in vnet_new() on vnet_exit()

2014-07-17T05:44:07+00:00

Nothing cleans up the objects created by
vnet_new(), they are completely leaked.

vnet_exit(), after doing the vio_unregister_driver() to clean
up ports, should call a helper function that iterates over vnet_list
and cleans up those objects. This includes unregister_netdevice()
as well as free_netdev().

r8169: Enable RX_MULTI_EN for RTL_GIGA_MAC_VER_40

2014-07-17T05:23:55+00:00

The ethernet port on my ASUS A88X Pro mainboard stopped working
several times a day, with messages like these in dmesg:

AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x001e address=0x0000000000003000 flags=0x0050]

Searching the web for these messages led me to similar reports about
different hardware supported by r8169, and eventually to commits
3ced8c955e74d319f3e3997f7169c79d524dfd06 ('r8169: enforce RX_MULTI_EN
for the 8168f.') and eb2dc35d99028b698cdedba4f5522bc43e576bd2 ('r8169:
RxConfig hack for the 8168evl'). So I tried this change, and it fixes
the problem for me.
