The RDMA stack allows for applications to create IB_QPT_RAW_PACKET
QPs, which receive plain Ethernet packets, specifically packets that
don't carry any QPN to be matched by the receiving side. Applications
using these QPs must be provided with a method to program some
steering rule with the HW so packets arriving at the local port can be
routed to them.This patch adds ib_create_flow(), which allow providing a flow
specification for a QP. When there's a match between the
specification and a received packet, the packet is forwarded to that
QP, in a the same way one uses ib_attach_multicast() for IB UD
multicast handling.Flow specifications are provided as instances of struct ib_flow_spec_yyy,
which describe L2, L3 and L4 headers. Currently specs for Ethernet, IPv4,
TCP and UDP are defined. Flow specs are made of values and masks.The input to ib_create_flow() is a struct ib_flow_attr, which contains
a few mandatory control elements and optional flow specs.struct ib_flow_attr {
enum ib_flow_attr_type type;
u16 size;
u16 priority;
u32 flags;
u8 num_of_specs;
u8 port;
/* Following are the optional layers according to user request
* struct ib_flow_spec_yyy
* struct ib_flow_spec_zzz
*/
};As these specs are eventually coming from user space, they are defined and
used in a way which allows adding new spec types without kernel/user ABI
change, just with a little API enhancement which defines the newly added spec.The flow spec structures are defined with TLV (Type-Length-Value)
entries, which allows calling ib_create_flow() with a list of variable
length of optional specs.For the actual processing of ib_flow_attr the driver uses the number
of specs and the size mandatory fields along with the TLV nature of
the specs.Steering rules processing order is according to the domain over which
the rule is set and the rule priority. All rules set by user space
applicatations fall into the IB_FLOW_DOMAIN_USER domain, other domains
could be used by future IPoIB RFS and Ethetool flow-steering interface
implementation. Lower numerical value for the priority field means
higher priority.The returned value from ib_create_flow() is a struct ib_flow, which
contains a database pointer (handle) provided by the HW driver to be
used when calling ib_destroy_flow().Applications that offload TCP/IP traffic can also be written over IB
UD QPs. The ib_create_flow() / ib_destroy_flow() API is designed to
support UD QPs too. A HW driver can set IB_DEVICE_MANAGED_FLOW_STEERING
to denote support for flow steering.The ib_flow_attr enum type supports usage of flow steering for promiscuous
and sniffer purposes:IB_FLOW_ATTR_NORMAL - "regular" rule, steering according to rule specification
IB_FLOW_ATTR_ALL_DEFAULT - default unicast and multicast rule, receive
all Ethernet traffic which isn't steered to any QPIB_FLOW_ATTR_MC_DEFAULT - same as IB_FLOW_ATTR_ALL_DEFAULT but only for multicast
IB_FLOW_ATTR_SNIFFER - sniffer rule, receive all port traffic
ALL_DEFAULT and MC_DEFAULT rules options are valid only for Ethernet link type.

NetLabel has the ability to selectively assign network security labels
to outbound traffic based on either the LSM's "domain" (different for
each LSM), the network destination, or a combination of both. Depending
on the type of traffic, local or forwarded, and the type of traffic
selector, domain or address based, different hooks are used to label the
traffic; the goal being minimal overhead.Unfortunately, there is a bug such that a system using NetLabel domain
based traffic selectors does not correctly label outbound local traffic
that is not assigned to a socket. The issue is that in these cases
the associated NetLabel hook only looks at the address based selectors
and not the domain based selectors. This patch corrects this by
checking both the domain and address based selectors so that the correct
labeling is applied, regardless of the configuration type.In order to acomplish this fix, this patch also simplifies some of the
NetLabel domainhash structures to use a more common outbound traffic
mapping type: struct netlbl_dommap_def. This simplifies some of the code
in this patch and paves the way for further simplifications in the
future.Signed-off-by: Paul Moore

It's possible to assign an invalid value to the net.core.somaxconn
sysctl variable, because there is no checks at all.The sk_max_ack_backlog field of the sock structure is defined as
unsigned short. Therefore, the backlog argument in inet_listen()
shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
is truncated to the somaxconn value. So, the somaxconn value shouldn't
exceed 65535 (USHRT_MAX).
Also, negative values of somaxconn are meaningless.before:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
net.core.somaxconn = 65536
$ sysctl -w net.core.somaxconn=-100
net.core.somaxconn = -100after:
$ sysctl -w net.core.somaxconn=256
net.core.somaxconn = 256
$ sysctl -w net.core.somaxconn=65536
error: "Invalid argument" setting key "net.core.somaxconn"
$ sysctl -w net.core.somaxconn=-100

Pull PCI fixes from Bjorn Helgaas:
"Yinghai fixed a couple regressions: one resource assignment problem
introduced in v3.10 that showed up with SR-IOV on powerpc, and another
SR-IOV hot-remove issue related to refcounting changes we merged for
v3.11.Yinghai is still working on another SR-IOV-related fix or two, which
will be simpler if pciehp is non-modular, so I included the Kconfig
changes now to get them in earlier.Finally, a minor fix for the ARM Marvell EBU host bridge driver that
was merged for v3.11Hotplug:
PCI: pciehp: Fix null pointer deref when hot-removing SR-IOV device

Pull ACPI and power management fixes from Rafael Wysocki:
- Revert two cpuidle commits added during the 3.8 development cycle
that turn out to have introduced a significant performance regression
as requested by Jeremy Eder.- The recent patches that made the freezer less heavy-weight introduced
a regression causing user-space-driven hibernation using the ioctl()
interface to block indefinitely when the hibernate process executes
try_to_freeze(). Fix from Colin Cross addresses this by adding a
process flag to mark the hibernate/suspend process to inform the
freezer that that process should be ignored.- One of the recent cpufreq reverts uncovered a problem in the core
causing the cpufreq driver module refcount to become negative after a
system suspend-resume cycle. Fix from Rafael J Wysocki.- The evaluation of the ACPI battery _BIX method has never worked
correctly, because the commit that added support for it forgot to
take the "Revision" field in the return package into account. As a
result, the reading of battery info doesn't work at all on some
systems, which is addressed by a fix from Lan Tianyu.* tag 'pm+acpi-3.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
freezer: set PF_SUSPEND_TASK flag on tasks that call freeze_processes
ACPI / battery: Fix parsing _BIX return value
cpufreq: Fix cpufreq driver module refcount balance after suspend/resume
