When testing GRE tunnel, I got: # ip tunnel show get tunnel gre0 failed: Invalid argument get tunnel gre1 failed: Invalid argument This is a regression introduced by commit c5441932 ("GRE: Refactor GRE tunneling code.") because previously we only check the parameters for SIOCADDTUNNEL and SIOCCHGTUNNEL, after that commit, the check is moved for all commands. So, just check for SIOCADDTUNNEL and SIOCCHGTUNNEL. After this patch I got: # ip tunnel show gre0: gre/ip remote any local any ttl inherit nopmtudisc gre1: gre/ip remote 192.168.122.101 local 192.168.122.45 ttl inherit Cc: Pravin B Shelar <pshelar@nicira.com> Cc: "David S.

We should get rid of all own SCTP debug printk macros and use the ones that the kernel offers anyway instead. This makes the code more readable and conform to the kernel code, and offers all the features of dynamic debbuging that pr_debug() et al has, such as only turning on/off portions of debug messages at runtime through debugfs. The runtime cost of having CONFIG_DYNAMIC_DEBUG enabled, but none of the debug statements printing, is negligible [1]. If kernel debugging is completly turned off, then these statements will also compile into "empty" functions. While we're at it, we also need to change the Kconfig option as it /now/ only refers to the ifdef'ed code portions in outqueue.c that enable further debugging/tracing of SCTP transaction fields. Also, since SCTP_ASSERT code was enabled with this Kconfig option and has now been removed, we transform those code parts into WARNs resp. where appropriate BUG_ONs so that those bugs can be more easily detected as probably not many people have SCTP debugging permanently turned on. To turn on all SCTP debugging, the following steps are needed: # mount -t debugfs none /sys/kernel/debug # echo -n 'module sctp +p' > /sys/kernel/debug/dynamic_debug/control This can be done more fine-grained on a per file, per line basis and others as described in [2].

In order to avoid making code that deals with printing both, IPv4 and IPv6 addresses, unnecessary complicated as for example ... if (sa.sa_family == AF_INET6) printk("... %pI6 ...", ..sin6_addr); else printk("... %pI4 ...", ..sin_addr.s_addr); ... it would be better to introduce a format specifier that can deal with those kind of situations internally; just as we have a "struct sockaddr" for generic mapping into "struct sockaddr_in" or "struct sockaddr_in6" as e.g. done in "union sctp_addr". Then, we could reduce the above statement into something like: printk("... %pIS ..", &sockaddr); In case our pointer is NULL, pointer() then deals with that already at an earlier point in time internally. While we're at it, support for both %piS/%pIS, where 'S' stands for sockaddr, comes (almost) for free. Additionally to that, postfix specifiers 'p', 'f' and 's' are supported as suggested and initially implemented in 2009 by Joe Perches [1]. Handling of those additional specifiers orientate on the initial RFC that was proposed. Also we support IPv6 compressed format specified by 'c' and various other IPv4 extensions as stated in the documentation part. Likely, there are many other areas than just SCTP in the kernel to make use of this extension as well.

The MC8305 module got an additional entry added based solely on information from a Windows driver *.inf file. We now have the actual descriptor layout from one of these modules, and it consists of two alternate configurations where cfg #1 is a normal Gobi 2k layout and cfg #2 is MBIM only, using interface numbers 5 and 6 for MBIM control and data.

John W. Linville says: ==================== Yet one more pull request for wireless updates intended for 3.11... For the mac80211 bits, Johannes says: "Here we have a few memory leak fixes related to BSS struct handling mostly from Ben, including a fix for a more theoretical problem (associating while a BSS struct times out) from myself, a compilation warning fix from Arend, mesh fixes from Thomas, tracking the beacon bitrate (Alex), a bandwidth change event fix (Ilan) and some initial work for 5/10 MHz channels from Simon." Regarding the iwlwifi bits, Johannes says: "Emmanuel removed some unneeded/unsupported module parameters and adds a Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have an older patch to add low-power receive support, this depended on a mac80211 commit that only just came in with the merge from wireless-next I did. Ilan made beacon timings better, and Eytan added some debug statements for thermal throttling. I have a few cleanups, a fix for a long-standing but rare warning, and, arguably the most important patch here, the firmware API version bump for the 7260/3160 devices." Also included is a Bluetooth pull -- Gustavo says: "Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes on the move of the Discovery to use the new request framework. Other than that Johan provided a bunch of fixes to the L2CAP code. The rest are just small fixes and clean ups." On top of all that, there are a variety of updates and fixes to brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and there. This also includes a pull of the wireless tree, in order to prevent some merge conflicts. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Within VST mode, enable modifying the vlan and/or qos for a VF without requiring unbind/rebind. This requires firmware which supports the UPDATE_QP command. (If the command is not available, we fall back to requiring unbind/bind to activate these changes). To avoid race conditions with modify-qp on QPs that are affected by update-qp, this operation is performed on the comm_wq. If the update operation succeeds for all the necessary QPs, a vlan_unregister is performed for the abandoned vlan id.

The common case is that TCP/IP checksums have already been verified, e.g. by hardware (rx checksum offload), or conntrack. Userspace can use this flag to determine when the checksum has not been validated yet. If the flag is set, this doesn't necessarily mean that the packet has an invalid checksum, e.g. if NIC doesn't support rx checksum. Userspace that sucessfully enabled NFQA_CFG_F_GSO queue feature flag can infer that IP/TCP checksum has already been validated if either the SKB_INFO attribute is not present or the NFQA_SKB_CSUM_NOTVERIFIED flag is unset.
