There are possible HW configurations in which PFs will have SR-IOV capability
but will have Max VFs set to 0 - this happens when there are Multi-Function
devices where the VFs are allocated to only some of the PFs.
DMAE is configured to support VFs only if the configuring PF has supported VFs.
In case the first PF to be loaded will be one without supported VFs, it will
not configure DMAE to the VF-supporting mode. When VFs of other PFs will be
loaded later on, they will not be able to communicate with their PF.
This changes the requirement for configuring DMAE for VF-supporting mode;
If the device has SR-IOV capabilities there must be some PF that has
max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

Since SR-IOV can be activated dynamically and iproute2 can be called
asynchronously, the various callbacks need a robust sanity check before
attempting to access the SR-IOV database and members since there are numerous
states in which it can find the driver (e.g., PF is down, sriov was not enabled
yet, VF is down, etc.).
In many of the states the callback result will be null pointer dereference.

After notification that DCBX configuration has ended arrived to the driver,
the driver configured the FW/HW in sleepless context.
As a result, it was possible to reach a race (mostly with CNIC registration)
in which the configuration will return a timeout, failing to set the DCBX
results correctly.
This patch moves the configuration following the DCBX end into the slowpath
RTNL task (i.e., sleepless context protected by the RTNL lock), allowing the
configuration to cope with such races.

Since commit 3deb816 "bnx2x: Add a periodic task for link PHY events"
link state changes can be detected not only via the attention flow but also
from the periodic task.
If the link state will change in such a manner (i.e., via the periodic task),
dropless flow-control will not be configured.
This patch remedies the issue, adding the missing configuration to all required
flows.

It is not allowed for an ipv6 packet to contain multiple fragmentation
headers. So discard packets which were already reassembled by
fragmentation logic and send back a parameter problem icmp.
The updates for RFC 6980 will come in later, I have to do a bit more
research here.

Because of the max_addresses check attackers were able to disable privacy
extensions on an interface by creating enough autoconfigured addresses:
<http://seclists.org/oss-sec/2012/q4/292>
But the check is not actually needed: max_addresses protects the
kernel to install too many ipv6 addresses on an interface and guards
addrconf_prefix_rcv to install further addresses as soon as this limit
is reached. We only generate temporary addresses in direct response of
a new address showing up. As soon as we filled up the maximum number of
addresses of an interface, we stop installing more addresses and thus
also stop generating more temp addresses.
Even if the attacker tries to generate a lot of temporary addresses
by announcing a prefix and removing it again (lifetime == 0) we won't
install more temp addresses, because the temporary addresses do count
to the maximum number of addresses, thus we would stop installing new
autoconfigured addresses when the limit is reached.
This patch fixes CVE-2013-0343 (but other layer-2 attacks are still
possible).
Thanks to Ding Tianhong to bring this topic up again.

In the previous commit, Richard Genoud fixed proc_root_readdir(), which
had lost the check for whether all of the non-process /proc entries had
been returned or not.
But that in turn exposed _another_ bug, namely that the original readdir
conversion patch had yet another problem: it had lost the return value
of proc_readdir_de(), so now checking whether it had completed
successfully or not didn't actually work right anyway.
This reinstates the non-zero return for the "end of base entries" that
had also gotten lost in commit f0c3b5093add ("[readdir] convert
procfs"). So now you get all the base entries *and* you get all the
process entries, regardless of getdents buffer size.
(Side note: the Linux "getdents" manual page actually has a nice example
application for testing getdents, which can be easily modified to use
different buffers. Who knew? Man-pages can be useful)

are relaxed in machine_crash_nonpanic_core() SMP function

machine_kexec() checks for number of cpus online.
If more than one cpu is online machine_kexec() fails to load
with below error

Commit f0c3b5093add ("[readdir] convert procfs") introduced a bug on the
listing of the proc file-system. The return value of proc_readdir()
isn't tested anymore in the proc_root_readdir function.
This lead to an "interesting" behaviour when we are using the getdents()
system call with a buffer too small: instead of failing, it returns the
first entries of /proc (enough to fill the given buffer), plus the PID
directories.
This is not triggered on glibc (as getdents is called with a 32KB
buffer), but on uclibc, the buffer size is only 1KB, thus some proc
entries are missing.
See https://lkml.org/lkml/2013/8/12/288 for more background.
