* crypto: ctr - make rfc3686 asynchronous block cipherJussi Kivilinna2013-01-083-63/+115
| | | | | | | | | | | | | | Some hardware crypto drivers register asynchronous ctr(aes), which is left unused in IPSEC because rfc3686 template only supports synchronous block ciphers. Some other drivers register rfc3686(ctr(aes)) to workaround this limitation but not all. This patch changes rfc3686 to use asynchronous block ciphers, to allow async ctr(aes) algorithms to be utilized automatically by IPSEC.

* xfrm_algo: probe asynchronous block ciphers instead of synchronousJussi Kivilinna2013-01-081-2/+1
| | | | | | | | | | | | | IPSEC uses block ciphers asynchronous, but probes only for synchronous block ciphers and makes ealg entries only available if synchronous block cipher is found. So with setup, where hardware crypto driver registers asynchronous block ciphers and software crypto module is not build, ealg is not marked as being available. Use crypto_has_ablkcipher instead and remove ASYNC mask. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

* drivers/net: remove orphaned references to micro channelPaul Gortmaker2013-01-077-16/+12
| | | | | | | | | | | We threw away the microchannel support, but the removal wasn't completely trivial since there was namespace overlap with the machine check support, and hence some orphaned dependencies survived the deletion.

| | | | | | | | | | | | | | As per suggestion from Eric Dumazet this patch makes tcp_ecn sysctl namespace aware. The reason behind this patch is to ease the testing of ecn problems on the internet and allows applications to tune their own use of ecn.

* net: splice: avoid high order page splittingEric Dumazet2013-01-071-29/+9
| | | | | | | | | | | | | splice() can handle pages of any order, but network code tries hard to split them in PAGE_SIZE units. Not quite successfully anyway, as __splice_segment() assumed poff < PAGE_SIZE. This is true for the skb->data part, not necessarily for the fragments.

* ndisc: Remove unused space at tail of skb for ndisc messages. (TAKE 3)YOSHIFUJI Hideaki / 吉藤英明2013-01-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the size of skb allocated for NDISC is MAX_HEADER + LL_RESERVED_SPACE(dev) + packet length + dev->needed_tailroom, but only LL_RESERVED_SPACE(dev) bytes is "reserved" for headers. As a result, the skb looks like this (after construction of the message): head data tail end +--------------------------------------------------------------+ + | | | | +--------------------------------------------------------------+ |<-hlen---->|<---ipv6 packet------>|<--tlen-->|<--MAX_HEADER-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom As the name implies, "MAX_HEADER" is used for headers, and should be "reserved" in prior to packet construction. Or, if some space is really required at the tail of ther skb, it should be explicitly documented. We have several option after construction of NDISC message: Option 1: head data tail end +---------------------------------------------+ + | | | +---------------------------------------------+ |<-hlen---->|<---ipv6 packet------>|<--tlen-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom Option 2: head data tail end +--------------------------------------------------+ + | | | +--------------------------------------------------+ |<--MAX_HEADER-->|<---ipv6 packet------>|<--tlen-->| = dev ->needed_ tailroom Option 3: head data tail end +--------------------------------------------------------------+ + | | | | +--------------------------------------------------------------+ |<--MAX_HEADER-->|<-hlen---->|<---ipv6 packet------>|<--tlen-->| =LL_ = dev RESERVED_ ->needed_ SPACE(dev) tailroom Our tunnel drivers try expanding headroom and the space for tunnel encapsulation was not a mandatory space -- so we are not seeing bugs here --, but just for optimization for performance critial situations. Since NDISC messages are not performance critical unlike TCP, and as we know outgoing device, LL_RESERVED_SPACE(dev) should be just enough for the device in most (if not all) cases: LL_RESERVED_SPACE(dev) <= LL_MAX_HEADER <= MAX_HEADER Note that LL_RESERVED_SPACE(dev) is also enough for NDISC over SIT (e.g., ISATAP). So, I think Option 1 is just fine here. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patchset adds a possibility to record upper device linkage. All upper<->lower devices are converted to use this mechanism right after. That leads to dev->master removal because this info becomes redundant since "master links" have the same value. After all changes, there is no longer possible to do things as: "bond->someotherdevice->samebond" Also I think that drivers like cxgb3, qlcnic, qeth would benefit by this in future by being able to get more appropriate info about l3 addresses. v5->v6: - netdev_has_upper_dev() - added statement to comment that this is looking at the immediate upper devices only. - renamed "RTNL semaphore" -> "RTNL lock" in all comments - renamed __netdev_has_upper_dev() to __netdev_search_upper_dev() to emhasize the difference to netdev_has_upper_dev() v4->v5: - fixed missed typo in drivers/infiniband/hw/nes/nes_cm.c v3->v4: - comments in __netdev_upper_dev_link() squashed into one line - kfree_rcu used instead of call_rcu in netdev_upper_dev_unlink() v2->v3: - removed recursion in __netdev_has_upper_dev() - refreshed bits to be applicable on current net-next v1->v2: - s/unique/master/ better naming + stays closer to the past - fixed vlan err goto - original patch 15 (WARN_ON change) is squashed into the first patch ==================== Signed-off-by: David S.
