mdiobus_free"
This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e.
As pointed out by Ben Hutchings, this change is not correct.
mdiobus_unregister() can't be called if the bus isn't registered yet,
however this change can result in situations which cause that to
happen.
Part of the confusion here revolves around the fact that the
callers of this module control registration/unregistration,
rather than the module itself.

The chip ready check added by the commit 3ac3546e [Always wait for
the chip to be ready] does not work when the register read/write
is word swapped. This check has been added before the WORD_SWAP
register is programmed, so we need to check for swapped register
value as well.
Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning
<steve@shawell.net> checked with SMSC and wrote:
The chip architects have concluded we should be reading PMT_CTRL
until we see any of bits 0, 8, 16 or 24 set. Then we should read
BYTE_TEST to check the byte order is correct (as we already do).
The rationale behind this is that some of the chip variants have
word order swapping features too, so the READY bit could actually
be in any of the 4 possible locations. The architects have confirmed
that if any of these 4 positions is set the chip is ready. The other
3 locations will either never be set or can only go high after READY
does (so also indicate the device is ready).
This change will check for the READY bit at the 16th position. We do
not check the other two cases (bit 8 and 24) since the driver does not
support byte-swapped register read/write.

In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet
on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable
in the driver init code, then tasklet_enable when it is opened. This makes
tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally,
drivers should use tasklet_init/tasklet_kill on device open/remove, and use
tasklet_disable/tasklet_enable on device suspend/resume.

With the latest kernel there are two things that must be done post decryption
so that the packet are forwarded.
1. Remove the mark from the packet. This will cause the packet to not match
the ipsec-policy again. However doing this causes the post-decryption check to
fail also and the packet will get dropped. (cat /proc/net/xfrm_stat).
2. Remove the sp association in the skbuff so that no policy check is done on
the packet for VTI tunnels.
Due to #2 above we must now do a security-policy check in the vti rcv path
prior to resetting the mark in the skbuff.

In the event of a VXLAN device being linked to a device that has a
hard_header_len greater than that of standard ethernet we could end up with
the hard_header_len not being large enough for outgoing frames. In order to
prevent this we should update the length when a lowerdev is provided.

This change fixes an issue I found where VXLAN frames were fragmented when
they were up to the VXLAN MTU size. I root caused the issue to the fact that
the headroom was 4 + 20 + 8 + 8. This math doesn't appear to be correct
because we are not inserting a VLAN header, but instead a 2nd Ethernet header.
As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the
extra headers that are inserted for VXLAN.

We added support for RFC 5961 in latest kernels but TCP fails
to perform exhaustive check of ACK sequence.
We can update our view of peer tsval from a frame that is
later discarded by tcp_ack()
This makes timestamps enabled sessions vulnerable to injection of
a high tsval : peers start an ACK storm, since the victim
sends a dupack each time it receives an ACK from the other peer.
As tcp_validate_incoming() is called before tcp_ack(), we should
not peform tcp_replace_ts_recent() from it, and let callers do it
at the right time.

A number of Huawei 3G and LTE modems implement a CDC NCM function,
including the necessary functional descriptors, but using a non
standard interface layout and class/subclass/protocol codes.
These devices can be handled by this driver with only a minor
change to the probing logic, allowing a single combined control
and data interface. This works because the devices
- include a CDC Union descriptor labelling the combined
interface as both master and slave, and
- have an alternate setting #1 for the bulk endpoints on the
combined interface.
The 3G/LTE network connection is managed by vendor specific AT
commands on a serial function in the same composite device.
Handling the managment function is out of the scope of this
driver. It will be handled by an appropriate USB serial
driver.

If the set_mac_address() function of qeth is invoked, qeth deletes
the old mac address first on OSA. Only if deletion returns
successfully the new mac address is set on OSA. Deletion may return
with a return value "MAC not found on OSA". In this case qeth
should continue setting the new mac address.
When the OSA cable is pulled, OSA forgets any set mac address. If
the OSA network interface acts as a slave to a bonding master
interface, bonding can invoke the set_mac_address function for
failover purposes and depends on successful setting of the new mac
address even though the old mac address could no longer be deleted.

(1<<optname) is undefined behavior in C with a negative optname or
optname larger than 31. In those cases the result of the shift is
not necessarily zero (e.g., on x86).

Pull networking fixes from David Miller:
"Bug fixes galore, mostly in drivers as is often the case:
1) USB gadget and cdc_eem drivers need adjustments to their frame size
lengths in order to handle VLANs correctly. From Ian Coolidge.
2) TIPC and several network drivers erroneously call tasklet_disable
before tasklet_kill, fix from Xiaotian Feng.
3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
fix from Cyril Brulebois.
4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
Nathan Walp.
5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
zero. From John Fastabend.
6) Fix smsc95xx tx checksum offload on big-endian, from Steve
Glendinning.
7) __inet_diag_dump() needs to repsect and report the error value
returned from inet_diag_lock_handler() rather than ignore it.
Otherwise if an inet diag handler is not available for a particular
protocol, we essentially report success instead of giving an error
indication. Fix from Cyrill Gorcunov.
8) When the QFQ packet scheduler sees TSO/GSO packets it does not
handle things properly, and in fact ends up corrupting it's
datastructures as well as mis-schedule packets. Fix from Paolo
Valente.
9) Fix oopser in skb_loop_sk(), from Eric Leblond.
10) CXGB4 passes partially uninitialized datastructures in to FW
commands, fix from Vipul Pandya.
11) When we send unsolicited ipv6 neighbour advertisements, we should
send them to the link-local allnodes multicast address, as per
RFC4861. Fix from Hannes Frederic Sowa.
12) There is some kind of bug in the usbnet's kevent deferral
mechanism, but more immediately when it triggers an uncontrolled
stream of kernel messages spam the log. Rate limit the error log
message triggered when this problem occurs, as sending thousands
of error messages into the kernel log doesn't help matters at all,
and in fact makes further diagnosis more difficult.

13) Fix gianfar restore from hibernation, from Wang Dongsheng.

for sparc again
This bug-fix makes sure that of_address_to_resource is defined extern for sparc
so that the sparc-specific implementation of of_address_to_resource() is once
again used when including include/linux/of_address.h in a sparc context. A
number of drivers in mainline relies on this function working for sparc.
The bug was introduced in a850a7554442f08d3e910c6eeb4ee216868dda1e, "of/address:
add empty static inlines for !CONFIG_OF". Contrary to that commit title, the
static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never
defined for sparc. This is good behavior for the other functions in
include/linux/of_address.h, as the extern functions defined in
drivers/of/address.c only gets linked when OF_ADDRESS is configured. However,
for of_address_to_resource there exists a sparc-specific implementation in
arch/sparc/arch/sparc/kernel/of_device_common.c

This adds sparc support for platform_get_irq that in the normal case use
platform_get_resource() to get an irq. This standard approach fails for sparc as
there are no resources of type IORESOURCE_IRQ for irqs for sparc.

sparc instead of having to have a special case for sparc.

If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.
For example:
~# ifconfig eth0 down
~# echo disk > /sys/power/state
<trigger a restore from hibernation>
~# ifconfig eth0 up
SIOCSIFFLAGS: No such device
This happens because the restore function bails out early upon
finding devices that were not up at hibernation. In doing so,
it never gets to the netif_device_attach call at the end of
the restore function. Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

In kswapd(), set current->reclaim_state to NULL before returning, as
current->reclaim_state holds reference to variable on kswapd()'s stack.
In rare cases, while returning from kswapd() during memory offlining,
__free_slab() and freepages() can access the dangling pointer of
current->reclaim_state.

Anders Blomdell noted in 2010 that Fanotify lost events and provided a
test case. Eric Paris confirmed it was a bug and posted a fix to the
list
https://groups.google.com/forum/?fromgroups=#!topic/linux.kernel/RrJfTfyW2BE
but never applied it. Repeated attempts over time to actually get him
to apply it have never had a reply from anyone who has raised it
So apply it anyway

Revert commit 03a7beb55b9f ("epoll: support for disabling items, and a
self-test app") pending resolution of the issues identified by Michael
Kerrisk, copied below.
We'll revisit this for 3.8.
: I've taken a look at this patch as it currently stands in 3.7-rc1, and
: done a bit of testing. (By the way, the test program
: tools/testing/selftests/epoll/test_epoll.c does not compile...)
:
: There are one or two places where the behavior seems a little strange,
: so I have a question or two at the end of this mail. But other than
: that, I want to check my understanding so that the interface can be
: correctly documented.
:
: Just to go though my understanding, the problem is the following
: scenario in a multithreaded application:
:
: 1. Multiple threads are performing epoll_wait() operations,
: and maintaining a user-space cache that contains information
: corresponding to each file descriptor being monitored by
: epoll_wait().
:
: 2. At some point, a thread wants to delete (EPOLL_CTL_DEL)
: a file descriptor from the epoll interest list, and
: delete the corresponding record from the user-space cache.
:
: 3. The problem with (2) is that some other thread may have
: previously done an epoll_wait() that retrieved information
: about the fd in question, and may be in the middle of using
: information in the cache that relates to that fd. Thus,
: there is a potential race.
:
: 4. The race can't solved purely in user space, because doing
: so would require applying a mutex across the epoll_wait()
: call, which would of course blow thread concurrency.
:
: Right?
:
: Your solution is the EPOLL_CTL_DISABLE operation. I want to
: confirm my understanding about how to use this flag, since
: the description that has accompanied the patches so far
: has been a bit sparse
:
: 0. In the scenario you're concerned about, deleting a file
: descriptor means (safely) doing the following:
: (a) Deleting the file descriptor from the epoll interest list
: using EPOLL_CTL_DEL
: (b) Deleting the corresponding record in the user-space cache
:
: 1. It's only meaningful to use this EPOLL_CTL_DISABLE in
: conjunction with EPOLLONESHOT.
:
: 2. Using EPOLL_CTL_DISABLE without using EPOLLONESHOT in
: conjunction is a logical error.
:
: 3. The correct way to code multithreaded applications using
: EPOLL_CTL_DISABLE and EPOLLONESHOT is as follows:
:
: a. All EPOLL_CTL_ADD and EPOLL_CTL_MOD operations should
: should EPOLLONESHOT.
:
: b. When a thread wants to delete a file descriptor, it
: should do the following:
:
: [1] Call epoll_ctl(EPOLL_CTL_DISABLE)
: [2] If the return status from epoll_ctl(EPOLL_CTL_DISABLE)
: was zero, then the file descriptor can be safely
: deleted by the thread that made this call.
: [3] If the epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY,
: then the descriptor is in use. In this case, the calling
: thread should set a flag in the user-space cache to
: indicate that the thread that is using the descriptor
: should perform the deletion operation.
:
: Is all of the above correct?
:
: The implementation depends on checking on whether
: (events & ~EP_PRIVATE_BITS) == 0
: This replies on the fact that EPOLL_CTL_AD and EPOLL_CTL_MOD always
: set EPOLLHUP and EPOLLERR in the 'events' mask, and EPOLLONESHOT
: causes those flags (as well as all others in ~EP_PRIVATE_BITS) to be
: cleared.
:
: A corollary to the previous paragraph is that using EPOLL_CTL_DISABLE
: is only useful in conjunction with EPOLLONESHOT. However, as things
: stand, one can use EPOLL_CTL_DISABLE on a file descriptor that does
: not have EPOLLONESHOT set in 'events' This results in the following
: (slightly surprising) behavior:
:
: (a) The first call to epoll_ctl(EPOLL_CTL_DISABLE) returns 0
: (the indicator that the file descriptor can be safely deleted).
: (b) The next call to epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY.
:
: This doesn't seem particularly useful, and in fact is probably an
: indication that the user made a logic error: they should only be using
: epoll_ctl(EPOLL_CTL_DISABLE) on a file descriptor for which
: EPOLLONESHOT was set in 'events'. If that is correct, then would it
: not make sense to return an error to user space for this case?
