* net: add __pskb_copy_fclone and pskb_copy_for_cloneOctavian Purdila2014-06-111-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several instances where a pskb_copy or __pskb_copy is immediately followed by an skb_clone. Add a couple of new functions to allow the copy skb to be allocated from the fclone cache and thus speed up subsequent skb_clone calls.

* cpumask: Utility function to set n'th cpu - local cpu firstAmir Vadai2014-06-111-0/+8
| | | | | | | | | | | | | | | | | | | | | This function sets the n'th cpu - local cpu's first. For example: in a 16 cores server with even cpu's local, will get the following values: cpumask_set_cpu_local_first(0, numa, cpumask) => cpu 0 is set cpumask_set_cpu_local_first(1, numa, cpumask) => cpu 2 is set ... cpumask_set_cpu_local_first(7, numa, cpumask) => cpu 14 is set cpumask_set_cpu_local_first(8, numa, cpumask) => cpu 1 is set cpumask_set_cpu_local_first(9, numa, cpumask) => cpu 3 is set ... cpumask_set_cpu_local_first(15, numa, cpumask) => cpu 15 is set Curently this function will be used by multi queue networking devices to calculate the irq affinity mask, such that as many local cpu's as possible will be utilized to handle the mq device irq's.

* net: sctp: migrate most recently used transport to ktimeDaniel Borkmann2014-06-111-3/+3
| | | | | | | | | | | Be more precise in transport path selection and use ktime helpers instead of jiffies to compare and pick the better primary and secondary recently used transports. This also avoids any side-effects during a possible roll-over, and could lead to better path decision-making. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S.

* net: filter: cleanup A/X name usageAlexei Starovoitov2014-06-111-72/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The macro 'A' used in internal BPF interpreter: #define A regs[insn->a_reg] was easily confused with the name of classic BPF register 'A', since 'A' would mean two different things depending on context. This patch is trying to clean up the naming and clarify its usage in the following way: - A and X are names of two classic BPF registers - BPF_REG_A denotes internal BPF register R0 used to map classic register A in internal BPF programs generated from classic - BPF_REG_X denotes internal BPF register R7 used to map classic register X in internal BPF programs generated from classic - internal BPF instruction format: struct sock_filter_int { __u8 code; /* opcode */ __u8 dst_reg:4; /* dest register */ __u8 src_reg:4; /* source register */ __s16 off; /* signed offset */ __s32 imm; /* signed immediate constant */ }; - BPF_X/BPF_K is 1 bit used to encode source operand of instruction In classic: BPF_X - means use register X as source operand BPF_K - means use 32-bit immediate as source operand In internal: BPF_X - means use 'src_reg' register as source operand BPF_K - means use 32-bit immediate as source operand Suggested-by: Chema Gonzalez <chema@google.com> Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Acked-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Chema Gonzalez <chema@google.com> Signed-off-by: David S.

* net: Support for multiple checksums with gsoTom Herbert2014-06-041-1/+25
| | | | | | | | | | | | | | | | | | | | | | When creating a GSO packet segment we may need to set more than one checksum in the packet (for instance a TCP checksum and UDP checksum for VXLAN encapsulation). To be efficient, we want to do checksum calculation for any part of the packet at most once. This patch adds csum_start offset to skb_gso_cb. This tracks the starting offset for skb->csum which is initially set in skb_segment. When a protocol needs to compute a transport checksum it calls gso_make_checksum which computes the checksum value from the start of transport header to csum_start and then adds in skb->csum to get the full checksum. skb->csum and csum_start are then updated to reflect the checksum of the resultant packet starting from the transport header. This patch also adds a flag to skbuff, encap_hdr_csum, which is set in *gso_segment fucntions to indicate that a tunnel protocol needs checksum calculation Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

| | * netlink: Only check file credentials for implicit destinationsEric W. Biederman2014-06-021-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was possible to get a setuid root or setcap executable to write to it's stdout or stderr (which has been set made a netlink socket) and inadvertently reconfigure the networking stack. To prevent this we check that both the creator of the socket and the currentl applications has permission to reconfigure the network stack. Unfortunately this breaks Zebra which always uses sendto/sendmsg and creates it's socket without any privileges. To keep Zebra working don't bother checking if the creator of the socket has privilege when a destination address is specified. Instead rely exclusively on the privileges of the sender of the socket. Note from Andy: This is exactly Eric's code except for some comment clarifications and formatting fixes. Neither I nor, I think, anyone else is thrilled with this approach, but I'm hesitant to wait on a better fix since 3.15 is almost here. Note to stable maintainers: This is a mess. An earlier series of patches in 3.15 fix a rather serious security issue (CVE-2014-0181), but they did so in a way that breaks Zebra. The offending series includes: commit aa4cf9452f469f16cea8c96283b641b4576d4a7b Author: Eric W. Biederman <ebiederm@xmission.com> Date: Wed Apr 23 14:28:03 2014 -0700 net: Add variants of capable for use on netlink messages If a given kernel version is missing that series of fixes, it's probably worth backporting it and this patch. if that series is present, then this fix is critical if you care about Zebra.

The reason is that when team_change_mtu() calls dev_set_mtu() for port device, notificator for NETDEV_PRECHANGEMTU event is called and team_device_event() returns NOTIFY_BAD forbidding the change. So fix this by returning NOTIFY_DONE here in case team is changing mtu in team_change_mtu().

This provides only the dummy alternative if the function is referenced by a built-in driver to allow a successful build. The filter function is only required by ATAGS based platforms, which will continue to be broken after this change for the bogus configuration. When booting from DT, with the dma channels correctly listed there, it will work fine.

And adds NDA_MASTER to bridge fdb notify msgs. Today bridge fdb notifications dont contain bridge information. Userspace can derive it from the port information in the fdb notification. However this is tricky in some scenarious. Example, bridge port delete notification comes before bridge fdb delete notifications. And we have seen problems in userspace when using libnl where, the bridge fdb delete notification handling code does not understand which bridge this fdb entry is part of because the bridge and port association has already been deleted. And these notifications (port membership and fdb) are generated on separate rtnl groups. Fixing the order of notifications could possibly solve the problem for some cases (I can submit a separate patch for that). This patch chooses to add NDA_MASTER to bridge fdb notify msgs because it not only solves the problem described above, but also helps userspace avoid another lookup into link msgs to derive the master index.

For the mac80211 bits, Johannes says: "The remainder for -next right now is mostly fixes, and a handful of small new things like some CSA infrastructure, the regdb script mW/dBm conversion change and sending wiphy notifications." For the bluetooth bits, Gustavo says: "Some more patches for 3.16. There is nothing really special here, just a bunch of clean ups, fixes plus some small improvements. Please pull." For the nfc bits, Samuel says: "We have: - Felica (Type3) tags support for trf7970a - Type 4b tags support for port100 - st21nfca DTS typo fix - A few sparse warning fixes" For the atheros bits, Kalle says: "Ben added support for setting antenna configurations. Michal improved warm reset so that we would not need to fall back to cold reset that often, an issue where ath10k stripped protected flag while in monitor mode and made module initialisation asynchronous to fix the problems with firmware loading when the driver is linked to the kernel. Luca removed unused channel_switch_beacon callbacks both from ath9k and ath10k. Marek fixed Protected Management Frames (PMF) when using Action Frames. Also we had other small fixes everywhere in the driver." Along with that, there are a handful of updates to a variety of drivers. This includes updates to at76c50x-usb, ath9k, b43, brcmfmac, mwifiex, rsi, rtlwifi, and wil6210. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
