1) If we're dumping the elements, then we have to check if the element

udp reuseport: fix packet of same flow hashed to different socket

There is a corner case in which udp packets belonging to a same
flow are hashed to different socket when hslot->count changes from 10
to 11:

1) When hslot->count <= 10, __udp_lib_lookup() searches udp_table->hash,
and always passes 'daddr' to udp_ehashfn().

2) When hslot->count > 10, __udp_lib_lookup() searches udp_table->hash2,
but may pass 'INADDR_ANY' to udp_ehashfn() if the sockets are bound to
INADDR_ANY instead of some specific addr.

That means when hslot->count changes from 10 to 11, the hash calculated by
udp_ehashfn() is also changed, and the udp packets belonging to a same
flow will be hashed to different socket.

This is easily reproduced:
1) Create 10 udp sockets and bind all of them to 0.0.0.0:40000.
2) From the same host send udp packets to 127.0.0.1:40000, record the
socket index which receives the packets.
3) Create 1 more udp socket and bind it to 0.0.0.0:44096. The number 44096
is 40000 + UDP_HASH_SIZE(4096), this makes the new socket put into the
same hslot as the aformentioned 10 sockets, and makes the hslot->count
change from 10 to 11.
4) From the same host send udp packets to 127.0.0.1:40000, and the socket
index which receives the packets will be different from the one received
in step 2.
This should not happen as the socket bound to 0.0.0.0:44096 should not
change the behavior of the sockets bound to 0.0.0.0:40000.

It's the same case for IPv6, and this patch also fixes that.

net: alx: Work around the DMA RX overflow issue

Commit 26c5f03 uses a new skb allocator to avoid the RFD overflow
issue.

But from debugging without datasheet, we found the error always
happen when the DMA RX address is set to 0x....fc0, which is very
likely to be a HW/silicon problem.

So one idea is instead of adding a new allocator, why not just
hitting the right target by avaiding the error-prone DMA address?

This patch will actually
* Remove the commit 26c5f03
* Apply rx skb with 64 bytes longer space, and if the allocated skb
  has a 0x...fc0 address, it will use skb_resever(skb, 64) to
  advance the address, so that the RX overflow can be avoided.

In theory this method should also apply to atl1c driver, which
I can't find anyone who can help to test on real devices.

net: mediatek: remove superfluous queue wake up call

The code checks if the queue should be stopped because we are below the
threshold of free descriptors only to check if it should be started again.
If we do end up in a state where we are at the threshold limit, it makes
more sense to just stop the queue and wait for the next IRQ to trigger the
TX housekeeping again. There is no rush in enqueuing the next packet, it
needs to wait for all the others in the queue to be dispatched first
anyway.

bridge: Fix incorrect re-injection of STP packets

Commit 8626c56c8279 ("bridge: fix potential use-after-free when hook
returns QUEUE or STOLEN verdict") fixed incorrect usage of NF_HOOK's
return value by consuming packets in okfn via br_pass_frame_up().

However, this function re-injects packets to the Rx path with skb->dev
set to the bridge device, which breaks kernel's STP, as all STP packets
appear to originate from the bridge device itself.

Instead, if STP is enabled and bridge isn't a 802.1ad bridge, then learn
packet's SMAC and inject it back to the Rx path for further processing
by the packet handlers.

The patch also makes netfilter's behavior consistent with regards to
packets destined to the Bridge Group Address, as no hook registered at
LOCAL_IN will ever be called, regardless if STP is enabled or not.

====================
Mellanox 100G mlx5 fixes for 4.7-rc

The following series provides some small fixes for mlx5 driver.

Two small fixes for the mlx5e netdev, the 1st is for the blue flame
quota accounting and the 2nd is a small refactoring in shutdown flow.

Five trivial fixes for mlx5 E-Switch.
- Allmulti mc_promisc flag was not set in a specific flow.
- Modify VF node guid when admin mac is changed.
- Race in vport enable flow.
- Misc code fixes (kvfree when needed and error pointers checking).

Three in mlx5 steering area.  Correct capabilities checking and root flow table update.

Three misc fixes in mlx5 commands enum and layouts.

8 years agonet/mlx5e: Fix blue flame quota logic
Eli Cohen [Thu, 9 Jun 2016 21:07:40 +0000 (00:07 +0300)]
net/mlx5e: Fix blue flame quota logic

Blue flame is a latency enhancement feature that allows the driver to
write the packet data directly to the NIC's registers thus making the
read of the packet data from host memory redundant.

We maintain a quota for the blue flame which is reloaded whenever we
identify that the hardware is processing send requests and processes
them fast enough so by the time we post the next send request it was
able to process all the pending ones. This indicates that the hardware
is capable of processing more blue flame requests efficiently. The blue
flame quota is decremented whenever we send using blue flame.

The current code erroneously clears the budget if we did not use blue
flame for the current post send operation and we fix it here.

8 years agomm: thp: broken page count after commit aa88b68c3b1d
Gerald Schaefer [Wed, 8 Jun 2016 22:33:50 +0000 (15:33 -0700)]
mm: thp: broken page count after commit aa88b68c3b1d

Christian Borntraeger reported a kernel panic after corrupt page counts,
and it turned out to be a regression introduced with commit aa88b68c3b1d
("thp: keep huge zero page pinned until tlb flush"), at least on s390.

put_huge_zero_page() was moved over from zap_huge_pmd() to
release_pages(), and it was replaced by tlb_remove_page().  However,
release_pages() might not always be triggered by (the arch-specific)
tlb_remove_page().

On s390 we call free_page_and_swap_cache() from tlb_remove_page(), and
not tlb_flush_mmu() -> free_pages_and_swap_cache() like the generic
version, because we don't use the MMU-gather logic.  Although both
functions have very similar names, they are doing very unsimilar things,
in particular free_page_xxx is just doing a put_page(), while
free_pages_xxx calls release_pages().

This of course results in very harmful put_page()s on the huge zero
page, on architectures where tlb_remove_page() is implemented in this
way.  It seems to affect only s390 and sh, but sh doesn't have THP
support, so the problem (currently) probably only exists on s390.

The following quick hack fixed the issue:

8 years agomm/hugetlb: fix huge page reserve accounting for private mappings
Mike Kravetz [Wed, 8 Jun 2016 22:33:42 +0000 (15:33 -0700)]
mm/hugetlb: fix huge page reserve accounting for private mappings

When creating a private mapping of a hugetlbfs file, it is possible to
unmap pages via ftruncate or fallocate hole punch.  If subsequent faults
repopulate these mappings, the reserve counts will go negative.  This is
because the code currently assumes all faults to private mappings will
consume reserves.  The problem can be recreated as follows:

 - mmap(MAP_PRIVATE) a file in hugetlbfs filesystem
 - write fault in pages in the mapping
 - fallocate(FALLOC_FL_PUNCH_HOLE) some pages in the mapping
 - write fault in pages in the hole

This will result in negative huge page reserve counts and negative
subpool usage counts for the hugetlbfs.  Note that this can also be
recreated with ftruncate, but fallocate is more straight forward.

This patch modifies the routines vma_needs_reserves and vma_has_reserves
to examine the reserve map associated with private mappings similar to
that for shared mappings.  However, the reserve map semantics for
private and shared mappings are very different.  This results in subtly
different code that is explained in the comments.
