| * netfilter: nf_tables: fix racy rule deletionPablo Neira Ayuso2014-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We may lost race if we flush the rule-set (which happens asynchronously via call_rcu) and we try to remove the table (that userspace assumes to be empty). Fix this by recovering synchronous rule and chain deletion. This was introduced time ago before we had no batch support, and synchronous rule deletion performance was not good. Now that we have the batch support, we can just postpone the purge of old rule in a second step in the commit phase. All object deletions are synchronous after this patch. As a side effect, we save memory as we don't need rcu_head per rule anymore.

Andrey Vagin reports that nf_conntrack_free can't be called for a conntrack with non-zero ref-counter, because it can race with nf_conntrack_find_get(). A conntrack slab is created with SLAB_DESTROY_BY_RCU. Non-zero ref-counter says that this conntrack is used. So when we release a conntrack with non-zero counter, we break this assumption.

* | net: ethoc: set up MII management bus clockMax Filippov2014-02-04
|/ | | | | | | | | | | | | | MII management bus clock is derived from the MAC clock by dividing it by MIIMODER register CLKDIV field value. This value may need to be set up in case it is undefined or its default value is too high (and communication with PHY is too slow) or too low (and communication with PHY is impossible). The value of CLKDIV is not specified directly, but is derived from the MAC clock for the default MII management bus frequency of 2.5MHz. The MAC clock may be specified in the platform data, or in the 'clocks' device tree attribute. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

So, when sending a datagram with ancillary data, the unicast and anycast addresses are handled in the same way. - Adds ipv6_chk_acast_addr_src() to check if an anycast address is link-local on given interface or is global. - Uses it in ip6_datagram_send_ctl().

| * reciprocal_divide: update/correction of the algorithmHannes Frederic Sowa2014-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jakub Zawadzki noticed that some divisions by reciprocal_divide() were not correct [1][2], which he could also show with BPF code after divisions are transformed into reciprocal_value() for runtime invariance which can be passed to reciprocal_divide() later on; reverse in BPF dump ended up with a different, off-by-one K in some situations. This has been fixed by Eric Dumazet in commit aee636c4809fa5 ("bpf: do not use reciprocal divide"). This follow-up patch improves reciprocal_value() and reciprocal_divide() to work in all cases by using Granlund and Montgomery method, so that also future use is safe and without any non-obvious side-effects. Known problems with the old implementation were that division by 1 always returned 0 and some off-by-ones when the dividend and divisor where very large. This seemed to not be problematic with its current users, as far as we can tell. Eric Dumazet checked for the slab usage, we cannot surely say so in the case of flex_array. Still, in order to fix that, we propose an extension from the original implementation from commit 6a2d7a955d8d resp. [3][4], by using the algorithm proposed in "Division by Invariant Integers Using Multiplication" [5], Torbjörn Granlund and Peter L. Montgomery, that is, pseudocode for q = n/d where q, n, d is in u32 universe: 1) Initialization: int l = ceil(log_2 d) uword m' = floor((1<<32)*((1<<l)-d)/d)+1 int sh_1 = min(l,1) int sh_2 = max(l-1,0) 2) For q = n/d, all uword: uword t = (n*m')>>32 q = (t+((n-t)>>sh_1))>>sh_2 The assembler implementation from Agner Fog [6] also helped a lot while implementing. We have tested the implementation on x86_64, ppc64, i686, s390x; on x86_64/haswell we're still half the latency compared to normal divide. Joint work with Daniel Borkmann.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add GRO handlers for protocols that do UDP encapsulation, with the intent of being able to coalesce packets which encapsulate packets belonging to the same TCP session. For GRO purposes, the destination UDP port takes the role of the ether type field in the ethernet header or the next protocol in the IP header. The UDP GRO handler will only attempt to coalesce packets whose destination port is registered to have gro handler. Use a mark on the skb GRO CB data to disallow (flush) running the udp gro receive code twice on a packet. This solves the problem of udp encapsulated packets whose inner VM packet is udp and happen to carry a port which has registered offloads.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data for IPv4 datagrams on IPv6 sockets. This patch splits the ip6_datagram_recv_ctl into two functions, one which handles both protocol families, AF_INET and AF_INET6, while the ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data. ip6_datagram_recv_*_ctl never reported back any errors, so we can make them return void. Also provide a helper for protocols which don't offer dual personality to further use ip6_datagram_recv_ctl, which is exported to modules. I needed to shuffle the code for ping around a bit to make it easier to implement dual personality for ping ipv6 sockets in future.
