Because we do make unaligned accesses past the filename, the

effectively depend on the fact that on x86 we don't really ever have the

12 years agovfs: get rid of batshit-insane pointless dentry hash calculations
Linus Torvalds [Mon, 19 Mar 2012 23:19:53 +0000 (16:19 -0700)]
vfs: get rid of batshit-insane pointless dentry hash calculations

For some odd historical reason, the final mixing round for the dentry
cache hash table lookup had an insane "xor with big constant" logic.  In
two places.

The big constant that is being xor'ed is GOLDEN_RATIO_PRIME, which is a
fairly random-looking number that is designed to be *multiplied* with so
that the bits get spread out over a whole long-word.

But xor'ing with it is insane.  It doesn't really even change the hash -
it really only shifts the hash around in the hash table.  To make
matters worse, the insane big constant is different on 32-bit and 64-bit
builds, even though the name hash bits we use are always 32-bit (and the
bits from the pointer we mix in effectively are too).

It's all total voodoo programming, in other words.

Now, some testing and analysis of the hash chains shows that the rest of
the hash function seems to be fairly good.  It does pick the right bits
of the parent dentry pointer, for example, and while it's generally a
bad idea to use an xor to mix down the upper bits (because if there is a
repeating pattern, the xor can cause "destructive interference"), it
seems to not have been a disaster.

For example, replacing the hash with the normal "hash_long()" code (that
uses the GOLDEN_RATIO_PRIME constant correctly, btw) actually just makes
the hash worse.  The hand-picked hash knew which bits of the pointer had
the highest entropy, and hash_long() ends up mixing bits less optimally
at least in some trivial tests.

So the hash function overall seems fine, it just has that really odd
"shift result around by a constant xor".

So get rid of the silly xor, and replace the down-mixing of the bits
with an add instead of an xor that tends to not have the same kind of
destructive interference issues.  Some stats on the resulting hash
chains shows that they look statistically identical before and after,
but the code is simpler and no longer makes you go "WTF?".

Also, the incoming hash really is just "unsigned int", not a long, and
there's no real point to worry about the high 26 bits of the dentry
pointer for the 64-bit case, because they are all going to be identical
anyway.

So also change the hashing to be done in the more natural 'unsigned int'
that is the real size of the actual hashed data anyway.

bonding: send igmp report for its master

Liang Zheng(lzheng@redhat.com) found that in the following topo,
bonding does not send igmp report when we trigger a fail-over of bonding.

eth0--
      |-- bond0 -- br0
eth1--

modprobe bonding mode=1 miimon=100 resend_igmp=10
ifconfig bond0 up
ifenslave bond0 eth0 eth1

brctl addbr br0
ifconfig br0 192.168.100.2/24 up
brctl addif br0 bond0

Add 192.168.100.2(br0) into a multicast group, like 224.10.10.10,
then trigger a fali-over in bonding.
You can see that parameter "resend_igmp" does not work.

The reason is that when we add br0 into a multicast group,
it does not propagate multicast knowledge down to its ports.

If we choose to propagate multicast knowledge down to all ports for bridge,
then we have to track every change that is done to bridge, and keep a backup
for all ports. It is hard to track, I think.

Instead I choose to modify bonding to send igmp report for its master.

Changelog:
V2: correct comments
V3: move this check into bond_resend_igmp_join_requests()
V4: only send igmp reports if bond is enslaved to a bridge

ixgbe: Fix issues with SR-IOV loopback when flow control is disabled

This patch allows us to avoid a Tx hang when SR-IOV is enabled.  This hang
can be triggered by sending small packets at a rate that was triggering Rx
missed errors from the adapter while the internal Tx switch and at least
one VF are enabled.

This was all due to the fact that under heavy stress the Rx FIFO never
drained below the flow control high water mark.  This resulted in the Tx
FIFO being head of line blocked due to the fact that it relies on the flow
control high water mark to determine when it is acceptable for the Tx to
place a packet in the Rx FIFO.

The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so
that even if the ring is almost completely full we can still place Tx
packets on the Rx ring and drop incoming Rx traffic if we do not have
sufficient space available in the Rx FIFO.

net/hyperv: Fix the code handling tx busy

Instead of dropping the packet, we keep the skb buffer, and return
NETDEV_TX_BUSY to let upper layer retry send. This will not cause
endless loop, because the host is taking data away from ring buffer,
and we have called the stop_queue before returning NETDEV_TX_BUSY.

The stop_queue was called in the function netvsc_send() in file
netvsc.c, then it returns to rndis_filter_send(), which returns to
netvsc_start_xmit() in file netvsc_drv.c. So the NETDEV_TX_BUSY is
indeed returned AFTER queue is stopped.

Resolve namespace issues when FCoE or DCB is not enabled.
The issue is with certain configurations we end up with namespace
problems. A simple example:

ixgbe_main.c
 - defines func A()
 - uses func A()

ixgbe_fcoe.c
 - uses func A()

ixgbe.h
 - has prototype for func A()

For default (FCoE included) all is good.  But when it isn't the namespace
checker complains about how func A() could be static.

To resolve this, created a ixgbe_lib file to contain functions used
by DCB/FCoE and their helper functions so that they are always in
namespace whether or not DCB/FCoE is enabled.

tcp: reduce out_of_order memory use

With increasing receive window sizes, but speed of light not improved
that much, out of order queue can contain a huge number of skbs, waiting
to be moved to receive_queue when missing packets can fill the holes.

Some devices happen to use fat skbs (truesize of 4096 + sizeof(struct
sk_buff)) to store regular (MTU <= 1500) frames. This makes highly
probable sk_rmem_alloc hits sk_rcvbuf limit, which can be 4Mbytes in
many cases.

When limit is hit, tcp stack calls tcp_collapse_ofo_queue(), a true
latency killer and cpu cache blower.

Doing the coalescing attempt each time we add a frame in ofo queue
permits to keep memory use tight and in many cases avoid the
tcp_collapse() thing later.

Tested on various wireless setups (b43, ath9k, ...) known to use big skb
truesize, this patch removed the "packets collapsed in receive queue due
to low socket buffer" I had before.

This also reduced average memory used by tcp sockets.

ixgbe: Correct flag values set by ixgbe_fix_features

This patch replaces the variable name data with the variable name features
for ixgbe_fix_features and ixgbe_set_features.  This helps to make some
issues more obvious such as the fact that we were disabling Rx VLAN tag
stripping when we should have been forcing it to be enabled when DCB is
enabled.

In addition there was deprecated code present that was disabling the LRO
flag if we had the itr value set too low.  I have updated this logic so
that we will now allow the LRO flag to be set, but will not enable RSC
until the rx-usecs value is high enough to allow enough time for Rx packet
coalescing.
