The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes. Thanks to Stephen Rothwell and Antonio Quartulli for help with several of these merge resolutions. Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-22net: sctp: minor: remove dead code from sctp_packetDaniel Borkmann
struct sctp_packet is currently embedded into sctp_transport or sits on the stack as 'singleton' in sctp_outq_flush(). Therefore, its member 'malloced' is always 0, thus a kfree() is never called. Because of that, we can just remove this code. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-22xen-netback: coalesce slots in TX path and fix regressionsWei Liu
This patch tries to coalesce tx requests when constructing grant copy structures. It enables netback to deal with situation when frontend's MAX_SKB_FRAGS is larger than backend's MAX_SKB_FRAGS. With the help of coalescing, this patch tries to address two regressions avoid reopening the security hole in XSA-39. Regression 1. The reduction of the number of supported ring entries (slots) per packet (from 18 to 17). This regression has been around for some time but remains unnoticed until XSA-39 security fix. This is fixed by coalescing slots. Regression 2. The XSA-39 security fix turning "too many frags" errors from just dropping the packet to a fatal error and disabling the VIF. This is fixed by coalescing slots (handling 18 slots when backend's MAX_SKB_FRAGS is 17) which rules out false positive (using 18 slots is legit) and dropping packets using 19 to `max_skb_slots` slots. To avoid reopening security hole in XSA-39, frontend sending packet using more than max_skb_slots is considered malicious. The behavior of netback for packet is thus: 1-18 slots: valid 19-max_skb_slots slots: drop and respond with an error max_skb_slots+ slots: fatal error max_skb_slots is configurable by admin, default value is 20. Also change variable name from "frags" to "slots" in netbk_count_requests. Please note that RX path still has dependency on MAX_SKB_FRAGS. This will be fixed with separate patch.

2013-04-22xen-netfront: reduce gso_max_size to account for max TCP headerWei Liu
The maximum packet including header that can be handled by netfront / netback wire format is 65535. Reduce gso_max_size accordingly. Drop skb and print warning when skb->len > 65535. This can 1) save the effort to send malformed packet to netback, 2) help spotting misconfiguration of netfront in the future.

2013-04-20net: fix incorrect credentials passingLinus Torvalds
Commit 257b5358b32f ("scm: Capture the full credentials of the scm sender") changed the credentials passing code to pass in the effective uid/gid instead of the real uid/gid. Obviously this doesn't matter most of the time (since normally they are the same), but it results in differences for suid binaries when the wrong uid/gid ends up being used. This just undoes that (presumably unintentional) part of the commit. Reported-by: Andy Lutomirski <luto@amacapital.net> Cc: Eric W. Biederman <ebiederm@xmission.com> Cc: Serge E.

2013-04-19irda: small read past the end of array in debug codeDan Carpenter
The "reason" can come from skb->data[] and it hasn't been capped so it can be from 0-255 instead of just 0-6. For example in irlmp_state_dtr() the code does: reason = skb->data[3]; ... irlmp_disconnect_indication(self, reason, skb); Also LMREASON has a couple other values which don't have entries in the irlmp_reasons[] array. And 0xff is a valid reason as well which means "unknown". So far as I can see we don't actually care about "reason" except for in the debug code.

2013-04-19net: socket: move ktime2ts to ktime header apiDaniel Borkmann
Currently, ktime2ts is a small helper function that is only used in net/socket.c. Move this helper into the ktime API as a small inline function, so that i) it's maintained together with ktime routines, and ii) also other files can make use of it. The function is named ktime_to_timespec_cond() and placed into the generic part of ktime, since we internally make use of ktime_to_timespec(). ktime_to_timespec() itself does not check the ktime variable for zero, hence, we name this function ktime_to_timespec_cond() for only a conditional conversion, and adapt its users to it.

2013-04-19netlink: implement memory mapped recvmsg()Patrick McHardy
Add support for mmap'ed recvmsg(). To allow the kernel to construct messages into the mapped area, a dataless skb is allocated and the data pointer is set to point into the ring frame. This means frames will be delivered to userspace in order of allocation instead of order of transmission. This usually doesn't matter since the order is either not determinable by userspace or message creation/transmission is serialized. The only case where this can have a visible difference is nfnetlink_queue. Userspace can't assume mmap'ed messages have ordered IDs anymore and needs to check this if using batched verdicts. For non-mapped sockets, nothing changes. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-18tcp: introduce TCPSpuriousRtxHostQueues SNMP counterEric Dumazet
Host queues (Qdisc + NIC) can hold packets so long that TCP can eventually retransmit a packet before the first transmit even left the host. Its not clear right now if we could avoid this in the first place : - We could arm RTO timer not at the time we enqueue packets, but at the time we TX complete them (tcp_wfree()) - Cancel the sending of the new copy of the packet if prior one is still in queue. This patch adds instrumentation so that we can at least see how often this problem happens.

Chao said that kdump does does work well on his system on 3.8 without extra parameter, even iommu does not work with kdump. And now have to append crashkernel_low=Y in first kernel to make kdump work. We have now modified crashkernel=X to allocate memory beyong 4G (if available) and do not allocate low range for crashkernel if the user does not specify that with crashkernel_low=Y. This causes regression if iommu is not enabled. Without iommu, swiotlb needs to be setup in first 4G and there is no low memory available to second kernel. Set crashkernel_low automatically if the user does not specify that. For system that does support IOMMU with kdump properly, user could specify crashkernel_low=0 to save that 72M low ram. -v3: add swiotlb_size() according to Konrad. -v4: add comments what 8M is for according to hpa. also update more crashkernel_low= in kernel-parameters.txt -v5: update changelog according to Vivek. -v6: Change description about swiotlb referring according to HATAYAMA.

Pull networking fixes from David Miller: 1) Fix erroneous netfilter drop of SIP packets generated by some Cisco phones, from Patrick McHardy. 2) Fix netfilter IPSET refcounting in list_set_add(), from Jozsef Kadlecsik. 3) Fix TCP syncookies route lookup key, we don't use the same values we would use for the usual SYN receive processing, from Dmitry Popov. 4) Fix NULL deref in bond_slave_netdev_event(), from Nikolay Aleksandrov. 5) When bonding enslave fails, we can forget to clear the IFF_BONDING bit, fix also from Nikolay Aleksandrov. 6) skb->csum_start is 16-bits, which is almost always just fine. But if we reallocate the headroom of an SKB this can push the skb->csum_start value outside of it's valid range. This can easily happen when collapsing multiple SKBs from the retransmit queue together. Fix from Thomas Graf. 7) Fix NULL deref in be2net driver due to missing check of __vlan_put_tag() return value, from Ivan Vecera. 8) tun_set_iff() returns zero instead of error code on failure, fix from Wei Yongjun. 9) Like GARP, 802 MRP needs to hold the app->lock when adding MAD events and queueing PDUs. Fix from David Ward. 10) Build fix, MVMDIO needs PHYLIB, from Thomas Petazzoni.. 11) Fix mac80211 static with ipv6 modular build, from Cong Wang. 12) If userland specifies a path cost explicitly, do not override it when the carrier state changes. From Stephen Hemminger. 13) mvnets calculates the TX queue to use incorrectly resulting in garbage pointer derefs and crashes, fix from Willy Tarreau. 14) cdc_mbim does erroneous sizeof(ETH_HLEN). Fix from Bjorn Mork. 15) IP fragmentation can leak a refcount-less route out from an RCU protected section. This results in crashes and all sorts of hard to diagnose behavior. Fix from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (24 commits) qlcnic: fix beaconing test for 82xx adapter net: drop dst before queueing fragments net: fec: fix regression in link change accounting net: cdc_mbim: remove bogus sizeof() drivers: net: ethernet: cpsw: get slave VLAN id from slave node instead of cpsw node net: mvneta: fix improper tx queue usage in mvneta_tx() esp4: fix error return code in esp_output() bridge: make user modified path cost sticky ipv6: statically link register_inet6addr_notifier() net: mvmdio: add select PHYLIB net/802/mrp: fix possible race condition when calling mrp_pdu_queue() tuntap: fix error return code in tun_set_iff() be2net: take care of __vlan_put_tag return value can: sja1000: fix handling on dt properties on little endian systems can: mcp251x: add missing IRQF_ONESHOT to request_threaded_irq netfilter: nf_nat: fix race when unloading protocol modules tcp: Reallocate headroom if it would overflow csum_start stmmac: prevent interrupt loop with MMC RX IPC Counter bonding: IFF_BONDING is not stripped on enslave failure bonding: fix netdev event NULL pointer dereference ...
2013-04-17fuse: fix type definitions in uapi headerMiklos Szeredi
Commit 7e98d53086d18c877cb44e9065219335184024de (Synchronize fuse header with one used in library) added #ifdef __linux__ around defines if it is not set. The kernel build is self-contained and can be built on non-Linux toolchains. After the mentioned commit builds on non-Linux toolchains will try to include stdint.h and fail due to -nostdinc, and then fail with a bunch of undefined type errors. Fix by checking for __KERNEL__ instead of __linux__ and using the standard int types instead of the linux specific ones.

2013-04-16vm: add vm_iomap_memory() helper functionLinus Torvalds
Various drivers end up replicating the code to mmap() their memory buffers into user space, and our core memory remapping function may be very flexible but it is unnecessarily complicated for the common cases to use. Our internal VM uses pfn's ("page frame numbers") which simplifies things for the VM, and allows us to pass physical addresses around in a denser and more efficient format than passing a "phys_addr_t" around, and having to shift it up and down by the page size. But it just means that drivers end up doing that shifting instead at the interface level. It also means that drivers end up mucking around with internal VM things like the vma details (vm_pgoff, vm_start/end) way more than they really need to. So this just exports a function to map a certain physical memory range into user space (using a phys_addr_t based interface that is much more natural for a driver) and hides all the complexity from the driver. Some drivers will still end up tweaking the vm_page_prot details for things like prefetching or cacheability etc, but that's actually relevant to the driver, rather than caring about what the page offset of the mapping is into the particular IO memory region.

2013-04-16vxlan: Allow setting destination to unicast address.Atzm Watanabe
This patch allows setting VXLAN destination to unicast address. It allows that VXLAN can be used as peer-to-peer tunnel without multicast. v4: generalize struct vxlan_dev, "gaddr" is replaced with vxlan_rdst. "GROUP" attribute is replaced with "REMOTE". they are based by David Stevens's comments. v3: move a new attribute REMOTE into the last of an enum list based by Stephen Hemminger's comments. v2: use a new attribute REMOTE instead of GROUP based by Cong Wang's comments.

We want to be able to use the utf16 functions that are currently present in the EFI variables code in platform-specific code as well. Move them to the kernel core, and in the process rename them to accurately describe what they do - they don't handle UTF16, only UCS2.

2013-04-15net: add dev_uc_sync_multiple() and dev_mc_sync_multiple() apiVlad Yasevich
The current implementation of dev_uc_sync/unsync() assumes that there is a strict 1-to-1 relationship between the source and destination of the sync. In other words, once an address has been synced to a destination device, it will not be synced to any other device through the sync API. However, there are some virtual devices that aggreate a number of lower devices and need to sync addresses to all of them. The current API falls short there. This patch introduces a new dev_uc_sync_multiple() api that can be called in the above circumstances and allows sync to work for every invocation.

There is actually no need to keep this member in the structure, because after init it's always 1 anyway, thus always kfree called. This seems to be an ancient leftover from the very initial implementation from 2.5 times. Only in case the initialization of an association fails, we leave base.malloced as 0, but we nevertheless kfree it in the error path in sctp_association_new().

2013-04-14net: sock: make sock_tx_timestamp voidDaniel Borkmann
Currently, sock_tx_timestamp() always returns 0. The comment that describes the sock_tx_timestamp() function wrongly says that it returns an error when an invalid argument is passed (from commit 20d4947353be, ``net: socket infrastructure for SO_TIMESTAMPING''). Make the function void, so that we can also remove all the unneeded if conditions that check for such a _non-existant_ error case in the output path.
