Preperatory patch for FRMR support. From connection info, we can retrieve cm_id which contains qp handled needed for work request posting. We also need to drop the RDS connection on QP error states where connection handle becomes useful. Signed-off-by:

RDS iWarp support code has become stale and non testable. As indicated earlier, am dropping the support for it. If new iWarp user(s) shows up in future, we can adapat the RDS IB transprt for the special RDMA READ sink case. iWarp needs an MR for the RDMA READ sink. Signed-off-by:

In case of problems when initializing the chip, the error flows aren't being properly done. Specifically, it's possible that the chip would be left in a configuration allowing it [internally] to access the host memory, causing fatal problems in the device that would require power cycle to overcome.

BB_A0 is a development model that is will not reach actual clients. In fact, future firmware would simply fail to initialize such chip. This changes the configuration into B0 instead of A0, and adds a safeguard against the slim chance someone would actually try this with an A0 adapter in which case probe would gracefully fail.

Use managed resource functions devm_kzalloc and pcim_enable_device to simplify error handling. Subsequently, remove unnecessary kfree, pci_disable_device and pci_release_regions. To be compatible with the change, various gotos are replaced with direct returns and unneeded labels are dropped. Also, `sc` was only being freed in the probe function and not the remove function before the change. By using devm_kzalloc this patch also fixes this memory leak. Signed-off-by:

Antonio Quartulli says: ==================== batman-adv 20160229 this is our (hopefully) latest batch of patches intended for net-next. With this patchset we finally introduce B.A.T.M.A.N. V: the latest version of our routing protocol. Technical documentation describing the protocol in more detail can be found in our wiki[1][2][3][4]. For what concerns this pull request, you can find the high level description right below. [1] https://www.open-mesh.org/projects/batman-adv/wiki/BATMAN_V [2] https://www.open-mesh.org/projects/batman-adv/wiki/OGMv2 [3] https://www.open-mesh.org/projects/batman-adv/wiki/ELP [4] https://www.open-mesh.org/projects/batman-adv/wiki/BATMAN_V_Tests ... With this patchset we finally introduce our new routing protocol: B.A.T.M.A.N. V. Its implementation started quite some years ago, but due to the big changes being introduced it took a while to be discussed, designed, worked, re-worked, tested and debugged (well, we're never done with the latest). The entire operation has basically been a team work involving all the core contributors together with other people interested in the project. The new protocol is divided into two main subcomponents, called respectively ELP and OGMv2. The former is in charge of dealing with the neighbour discovery and link quality estimation, while the latter implements the algorithm that spreads the metrics around the network and computes optimal paths. The biggest change introduced with B.A.T.M.A.N. V is the new metric: the protocol won't rely on packet loss anymore, but it will use the estimated throughput extracted directly from the wifi driver (when available) by querying cfg80211. Batman-adv will also send some unicast probing packets when an interface is not used for payload traffic to make sure that such values are current. The new protocol can be compiled-in or not like other features we have and when selected will pull in CFG80211 as dependency for the reason described above. Thanks to the big work brought up in the past by Marek Lindner, batman-adv can easily deal several protocol implementations, therefore compiling in this new version does not exclude the older. This means that the user is offered the option to choose the protocol when creating the mesh interface (default is the old one to keep backward compatibility). Along with the protocol there are some sysfs knobs that are introduced to fine tune some of its behaviours, but users are recommended to keep the default values unless they know what they are doing. The last patch is about advertising our own patchwork platform (thanks to Sven Eckelmann for having set that up!) in the MAINTAINERS file. ==================== Signed-off-by:

of_mdiobus_register() declares the 'paddr' variable to hold the result of the of_get_property() but only uses it once after that while the function can be called directly from the *if* statement. Remove that variable and switch to calling of_find_property() instead since we don't care about the "reg" property's value anyway... Signed-off-by:

Yuval Mintz says: ==================== qed: Attention support patch series Until now we've only enabled attention generation for the sake of management firmware indications [required for link notifications]. This series enables [almost] all the attention sources of the HW, currently for the sake of logging information relating to issues experienced by HW. In future, infrastructure laid here would also be used for the sake of the recovery process. The first patch in the series is a semantic alignemnt of the code. The later 3 patches incremently create said infrastructure and enrich the logged information. Notice #3 contains quite a bit of structures [consisting of ~1K lines] that will eventually be removed and incorporated in the binary fw file. ==================== Signed-off-by: -

This patch utilizes the attention infrastructure to log additional information that relates only to specific HW blocks. For some of those HW blocks, it also stops automatically disabling the attention generation as the attention is considered benign and thus should only be logged; No fear of it flooding the system.

HW is capable of generating attentnions for a multitude of reasons, but current driver is enabling attention generation only for management firmware [required for link notifications]. This patch enables almost all of the possible reasons for HW attentions, logging the HW block generating the attention and preventing further attentions from that source [to prevent possible attention flood]. It also lays the infrastructure for additional exploration of the various attentions. Signed-off-by:

Saeed Mahameed says: ==================== mlx5 driver updates This series includes some bug fixes and updates for the mlx5 core and ethernet driver. From Gal, two fixes that protects the update CQ moderation flows when it is not allowed. From Moshe, two fixes for the core and ethernet driver in non-cached(NC) and write combining(WC) buffers mappings, which prevents the driver from double memory mappings. From Or, reduce the firmware command completion timeout. From Tariq, several small trivial fixes. Changes from v0: - "Fix global UAR mapping" commit messages updated to explain ARCH_HAS_IOREMAP_WC usage. - rebased to commit 8d3f2806 'Merge branch ethtool-ksettings' Changes from v1: - Removed ARCH_HAS_IOREMAP_WC config flag from "Fix global UAR mapping" commit, as it was not accurate to use it. - Squashed "Fix global UAR mapping" and "net/mlx5: Avoid double mapping of io mapped memory" - Added more info for "Fix global UAR mapping" in commit message Changes from v2: - None. resubmission per Dave's request due to two parallel submissions to mlx5 driver. ==================== Signed-off-by:

Avoid double mapping of io mapped memory, Device page may be mapped to non-cached(NC) or to write-combining(WC). The code before this fix tries to map it both to WC and NC contrary to what stated in Intel's software developer manual. Here we remove the global WC mapping of all UARS "dev->priv.bf_mapping", since UAR mapping should be decided per UAR (e.g we want different mappings for EQs, CQs vs QPs). Caller will now have to choose whether to map via write-combining API or not. mlx5e SQs will choose write-combining in order to perform BlueFlame writes.

Commit f1705ec1 allows IPv6 addresses to be retained on a link down. The address can have a cached host route which can point to the wrong FIB table if the L3 enslavement is changed (e.g., route can point to local table instead of VRF table if device is added to an L3 domain). On link up check the table of the cached host route against the FIB table associated with the device and correct if needed. Signed-off-by:

All patches can be reviewed and merged independently. Socket timestamps and ioctl calls will be handled separately. Thanks to Arnd Bergmann for discussing solution options with me. Solution: Data type struct timespec is not y2038 safe. Replace timespec with struct timespec64 which is y2038 safe.
