2013-10-17tty/serial: at91: fix uart/usart selection for older productsNicolas Ferre
Since commit 055560b04a8cd063aea916fd083b7aec02c2adb8 (serial: at91: distinguish usart and uart) the older products which do not have a name field in their register map are unable to use their serial output. As the main console output is usually the serial interface (aka DBGU) it is pretty unfortunate. So, instead of failing during probe() we just silently configure the serial peripheral as an uart. It allows us to use these serial outputs. The proper solution is proposed in another patch.

2013-10-17bridge: Correctly clamp MAX forward_delay when enabling STPVlad Yasevich
Commit be4f154d5ef0ca147ab6bcd38857a774133f5450 bridge: Clamp forward_delay when enabling STP had a typo when attempting to clamp maximum forward delay. It is possible to set bridge_forward_delay to be higher then permitted maximum when STP is off. When turning STP on, the higher then allowed delay has to be clamed down to max value.

2013-10-17tcp: remove the sk_can_gso() check from tcp_set_skb_tso_segs()Eric Dumazet
sk_can_gso() should only be used as a hint in tcp_sendmsg() to build GSO packets in the first place. (As a performance hint) Once we have GSO packets in write queue, we can not decide they are no longer GSO only because flow now uses a route which doesn't handle TSO/GSO. Core networking stack handles the case very well for us, all we need is keeping track of packet counts in MSS terms, regardless of segmentation done later (in GSO or hardware) Right now, if tcp_fragment() splits a GSO packet in two parts, @left and @right, and route changed through a non GSO device, both @left and @right have pcount set to 1, which is wrong, and leads to incorrect packet_count tracking.

2013-10-17tcp: must unclone packets before mangling themEric Dumazet
TCP stack should make sure it owns skbs before mangling them. We had various crashes using bnx2x, and it turned out gso_size was cleared right before bnx2x driver was populating TC descriptor of the _previous_ packet send. TCP stack can sometime retransmit packets that are still in Qdisc. Of course we could make bnx2x driver more robust (using ACCESS_ONCE(shinfo->gso_size) for example), but the bug is TCP stack. We have identified two points where skb_unclone() was needed. This patch adds a WARN_ON_ONCE() to warn us if we missed another fix of this kind. Kudos to Neal for finding the root cause of this bug.

2013-10-17tcp: fix incorrect ca_state in tail loss probeYuchung Cheng
On receiving an ACK that covers the loss probe sequence, TLP immediately sets the congestion state to Open, even though some packets are not recovered and retransmisssion are on the way. The later ACks may trigger a WARN_ON check in step D of tcp_fastretrans_alert(), e.g., https://bugzilla.redhat.com/show_bug.cgi?id=989251 The fix is to follow the similar procedure in recovery by calling tcp_try_keep_open(). The sender switches to Open state if no packets are retransmissted. Otherwise it goes to Disorder and let subsequent ACKs move the state to Recovery or Open.

For now, we disable the extended MMAP record support (MMAP2). We have identified cases where it would not report the correct mapping information, clone(VM_CLONE) but with separate pids. We will revisit the support once we find a solution for this case. The patch changes the kernel to return EINVAL if attr->mmap2 is set. The patch also modifies the perf tool to use regular PERF_RECORD_MMAP for synthetic events and it also prevents the tool from requesting attr->mmap2 mode because the kernel would reject it. The support will be revisited once the kenrel interface is updated. In V2, we reduce the patch to the strict minimum. In V3, we avoid calling perf_event_open() with mmap2 set because we know it will fail and require fallback retry.

git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nftables Pablo Neira Ayuso says: ==================== netfilter updates: nf_tables pull request The following patchset contains the current original nf_tables tree condensed in 17 patches. I have organized them by chronogical order since the original nf_tables code was released in 2009 and by dependencies between the different patches. The patches are: 1) Adapt all existing hooks in the tree to pass hook ops to the hook callback function, required by nf_tables, from Patrick McHardy. 2) Move alloc_null_binding to nf_nat_core, as it is now also needed by nf_tables and ip_tables, original patch from Patrick McHardy but required major changes to adapt it to the current tree that I made. 3) Add nf_tables core, including the netlink API, the packet filtering engine, expressions and built-in tables, from Patrick McHardy. This patch includes accumulated fixes since 2009 and minor enhancements. The patch description contains a list of references to the original patches for the record. For those that are not familiar to the original work, see [1], [2] and [3]. 4) Add netlink set API, this replaces the original set infrastructure to introduce a netlink API to add/delete sets and to add/delete set elements. This includes two set types: the hash and the rb-tree sets (used for interval based matching). The main difference with ipset is that this infrastructure is data type agnostic. Patch from Patrick McHardy. 5) Allow expression operation overload, this API change allows us to provide define expression subtypes depending on the configuration that is received from user-space via Netlink. It is used by follow up patches to provide optimized versions of the payload and cmp expressions and the x_tables compatibility layer, from Patrick McHardy. 6) Add optimized data comparison operation, it requires the previous patch, from Patrick McHardy. 7) Add optimized payload implementation, it requires patch 5, from Patrick McHardy. 8) Convert built-in tables to chain types. Each chain type have special semantics (filter, route and nat) that are used by userspace to configure the chain behaviour. The main chain regarding iptables is that tables become containers of chain, with no specific semantics. However, you may still configure your tables and chains to retain iptables like semantics, patch from me. 9) Add compatibility layer for x_tables. This patch adds support to use all existing x_tables extensions from nf_tables, this is used to provide a userspace utility that accepts iptables syntax but used internally the nf_tables kernel core. This patch includes missing features in the nf_tables core such as the per-chain stats, default chain policy and number of chain references, which are required by the iptables compatibility userspace tool. Patch from me. 10) Fix transport protocol matching, this fix is a side effect of the x_tables compatibility layer, which now provides a pointer to the transport header, from me. 11) Add support for dormant tables, this feature allows you to disable all chains and rules that are contained in one table, from me. 12) Add IPv6 NAT support. At the time nf_tables was made, there was no NAT IPv6 support yet, from Tomasz Bursztyka. 13) Complete net namespace support. This patch register the protocol family per net namespace, so tables (thus, other objects contained in tables such as sets, chains and rules) are only visible from the corresponding net namespace, from me. 14) Add the insert operation to the nf_tables netlink API, this requires adding a new position attribute that allow us to locate where in the ruleset a rule needs to be inserted, from Eric Leblond. 15) Add rule batching support, including atomic rule-set updates by using rule-set generations. This patch includes a change to nfnetlink to include two new control messages to indicate the beginning and the end of a batch. The end message is interpreted as the commit message, if it's missing, then the rule-set updates contained in the batch are aborted, from me. 16) Add trace support to the nf_tables packet filtering core, from me. 17) Add ARP filtering support, original patch from Patrick McHardy, but adapted to fit into the chain type infrastructure. This was recovered to be used by nft userspace tool and our compatibility arptables userspace tool. There is still work to do to fully replace x_tables [4] [5] but that can be done incrementally by extending our netlink API. Moreover, looking at netfilter-devel and the amount of contributions to nf_tables we've been getting, I think it would be good to have it mainstream to avoid accumulating large patchsets skip continuous rebases. I tried to provide a reasonable patchset, we have more than 100 accumulated patches in the original nf_tables tree, so I collapsed many of the small fixes to the main patch we had since 2009 and provide a small batch for review to netdev, while trying to retain part of the history. For those who didn't give a try to nf_tables yet, there's a quick howto available from Eric Leblond that describes how to get things working [6]. Comments/reviews welcome. Thanks!

Mellanox ConnectX architecture is: mlx4_core is the lower level PCI driver which register on the PCI id, and protocol specific drivers are depended on it: mlx4_en - for Ethernet and mlx4_ib for Infiniband. NIC could have multiple ports which can change their type dynamically. We use the request_module() call to load the relevant protocol driver when needed: on loading time or at port type change event.
