10 years agonetfilter: nft_hash: bug fixes and resizing
Patrick McHardy [Tue, 4 Mar 2014 15:21:51 +0000 (16:21 +0100)]
netfilter: nft_hash: bug fixes and resizing

The hash set type is very broken and was never meant to be merged in this
state. Missing RCU synchronization on element removal, leaking chain
refcounts when used as a verdict map, races during lookups, a fixed table
size are probably just some of the problems. Luckily it is currently
never chosen by the kernel when the rbtree type is also available.

Rewrite it to be usable.

The new implementation supports automatic hash table resizing using RCU,
based on Paul McKenney's and Josh Triplett's algorithm "Optimized Resizing
For RCU-Protected Hash Tables" described in [1].

Resizing doesn't require a second list head in the elements, it works by
chosing a hash function that remaps elements to a predictable set of buckets,
only resizing by integral factors and

- during expansion: linking new buckets to the old bucket that contains
  elements for any of the new buckets, thereby creating imprecise chains,
  then incrementally seperating the elements until the new buckets only
  contain elements that hash directly to them.

- during shrinking: linking the hash chains of all old buckets that hash
  to the same new bucket to form a single chain.

Expansion requires at most the number of elements in the longest hash chain
grace periods, shrinking requires a single grace period.

Due to the requirement of having hash chains/elements linked to multiple
buckets during resizing, homemade single linked lists are used instead of
the existing list helpers, that don't support this in a clean fashion.
As a side effect, the amount of memory required per element is reduced by
one pointer.

Expansion is triggered when the load factors exceeds 75%, shrinking when
the load factor goes below 30%. Both operations are allowed to fail and
will be retried on the next insertion or removal if their respective
conditions still hold.

netfilter: conntrack: remove central spinlock nf_conntrack_lock

nf_conntrack_lock is a monolithic lock and suffers from huge contention
on current generation servers (8 or more core/threads).

Perf locking congestion is clear on base kernel:

-  72.56%  ksoftirqd/6  [kernel.kallsyms]    [k] _raw_spin_lock_bh
   - _raw_spin_lock_bh
      + 25.33% init_conntrack

+   0.55%  ksoftirqd/6  [ip_tables]          [k] ipt_do_table

This patch change conntrack locking and provides a huge performance
improvement.  SYN-flood attack tested on a 24-core E5-2695v2(ES) with
10Gbit/s ixgbe (with tool trafgen):

 Base kernel:   810.405 new conntrack/sec
 After patch: 2.233.876 new conntrack/sec

Notice other floods attack (SYN+ACK or ACK) can easily be deflected using:
 # iptables -A INPUT -m state --state INVALID -j DROP
 # sysctl -w net/netfilter/nf_conntrack_tcp_loose=0

Use an array of hashed spinlocks to protect insertions/deletions of
conntracks into the hash table. 1024 spinlocks seem to give good
results, at minimal cost (4KB memory). Due to lockdep max depth,
1024 becomes 8 if CONFIG_LOCKDEP=y

The hash resize is a bit tricky, because we need to take all locks in
the array. A seqcount_t is used to synchronize the hash table users
with the resizing process.

netfilter: ipset: Follow manual page behavior for SET target on list:set

ipset(8) for list:set says:
  The match will try to find a matching entry in the sets and the
  target will try to add an entry to the first set to which it can
  be added.

However real behavior is bit differ from described. Consider example:

 # ipset create test-1-v4 hash:ip family inet
 # ipset create test-1-v6 hash:ip family inet6
 # ipset create test-1 list:set
 # ipset add test-1 test-1-v4
 # ipset add test-1 test-1-v6

 # iptables  -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src
 # ip6tables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src

And then when iptables/ip6tables rule matches packet IPSET target
tries to add src from packet to the list:set test-1 where first
entry is test-1-v4 and the second one is test-1-v6.

For IPv4, as it first entry in test-1 src added to test-1-v4
correctly, but for IPv6 src not added!

Placing test-1-v6 to the first element of list:set makes behavior
correct for IPv6, but brokes for IPv4.

This is due to result, returned from ip_set_add() and ip_set_del() from
net/netfilter/ipset/ip_set_core.c when set in list:set equires more
parameters than given or address families do not match (which is this
case).

It seems wrong returning 0 from ip_set_add() and ip_set_del() in
this case, as 0 should be returned only when an element successfuly
added/deleted to/from the set, contrary to ip_set_test() which
returns 0 when no entry exists and >0 when entry found in set.

of_mdio: fix phy interrupt passing

The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.

Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:

- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above

Please pull this batch of fixes intended for the 3.14 stream...

For the iwlwifi one, Emmanuel says:

"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."

On top of that...

Dan Carpenter fixes a typo/thinko in ath5k.

Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),

Merge branch 'bonding'

Veaceslav Falico says:

====================
bonding: add an option to rely on unvalidated arp packets

v4 -> v5:
Again per Nik's advise correct the bond_opts restrictions for arp_validate
- set it the same as arp_interval.

v3 -> v4:
Per Nikolay's advise, remove the new bond_opts restriction on modes setting
for arp_validate.

v2 -> v3:
Per Jay's advise, use the 'filter' keyword instead of 'arp' one, and use
his text for documentation. Also, rebase on the latest net-next. Sorry for
the delay, didn't manage to send it before net-next was closed.

v1 -> v2:
Don't remove the 'all traffic' functionality - rather, add new arp_validate
options to specify that we want *only* unvalidated arps.

Currently, if arp_validate is off (0), slave_last_rx() returns the
slave->dev->last_rx, which is always updated on *any* packet received by
slave, and not only arps. This means that, if the validation of arps is
off, we're treating *any* incoming packet as a proof of slave being up, and
not only arps.

This might seem logical at the first glance, however it can cause a lot of
troubles and false-positives, one example would be:

The arp_ip_target is NOT accessible, however someone in the broadcast domain
spams with any broadcast traffic. This way bonding will be tricked that the
slave is still up (as in - can access arp_ip_target), while it's not.

The net_device->last_rx is already used in a lot of drivers (even though the
comment states to NOT do it :)), and it's also ugly to modify it from bonding.

However, some loadbalance setups might rely on the fact that even non-arp
traffic is a sign of slave being up - and we definitely can't break anyones
config - so an extension to arp_validate is needed.

So, to fix this, add an option for the user to specify if he wants to
filter out non-arp traffic on unvalidated slaves, remove the last_rx from
bonding, *always* call bond_arp_rcv() in slave's rx_handler (which is
bond_handle_frame), and if we spot an arp there with this option on - update
the slave->last_arp_rx - and use it instead of net_device->last_rx. Finally,
rename last_arp_rx to last_rx to reflect the changes.

Also rename slave->jiffies to ->last_link_up, to reflect better its
meaning, add the new option's documentation and update the arp_validate one
to be a bit more descriptive.

10 years agonet: sctp: fix sctp_connectx abi for ia32 emulation/compat mode
Daniel Borkmann [Mon, 17 Feb 2014 11:11:11 +0000 (12:11 +0100)]
net: sctp: fix sctp_connectx abi for ia32 emulation/compat mode

SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit
emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of
'struct sctp_getaddrs_old' which includes a struct sockaddr pointer,
sizeof(param) check will always fail in kernel as the structure in
64bit kernel space is 4bytes larger than for user binaries compiled
in 32bit mode. Thus, applications making use of sctp_connectx() won't
be able to run under such circumstances.

Introduce a compat interface in the kernel to deal with such
situations by using a 'struct compat_sctp_getaddrs_old' structure
where user data is copied into it, and then sucessively transformed
into a 'struct sctp_getaddrs_old' structure with the help of
compat_ptr(). That fixes sctp_connectx() abi without any changes
needed in user space, and lets the SCTP test suite pass when compiled
in 32bit and run on 64bit kernels.
