Paging contains 3 sections in the fw. The first for the paging separator, The second for the CSS block, the third with the paging data. Currently if the driver finds the paging separator, and there is only section left (CSS), once reading the CSS section, the driver will attempt to read the paging data and will go out of the arrays bounds. Make sure that the FW image contains the right amount of sections for paging. Signed-off-by: NMatti Gottlieb <matti.gottlieb@intel.com> Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

Currently the driver has 2 buffers for paging: 1. paging db - this contains all of the pages that were in the FW image, that the driver stores for the FW. This is allocated for each block separately (not contiguous). 2. download buffer - we need to provide this empty buffer for the iwl_sdio_load_fw_chunk function to copy the requested pages to the shared memory. This is one big buffer of contiguous memory whose size is the size of all the blocks that the fw paging section can contain. This download buffer size is too big, and causes the allocation to fail sometimes. Since the driver allocates memory for each block separately, it is not possible for the FW to request all of the pages in one request (the FW gives an address and size, so blocks need to be contiguous for this to happen), therefore the FW is limited to request only one block. Decrease the size of the paging download buffer to be the size of a paging block.

Pull networking updates from David Miller: "Highlights: 1) Support more Realtek wireless chips, from Jes Sorenson. 2) New BPF types for per-cpu hash and arrap maps, from Alexei Starovoitov. 3) Make several TCP sysctls per-namespace, from Nikolay Borisov. 4) Allow the use of SO_REUSEPORT in order to do per-thread processing of incoming TCP/UDP connections. The muxing can be done using a BPF program which hashes the incoming packet. From Craig Gallek. 5) Add a multiplexer for TCP streams, to provide a messaged based interface. BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported. From David Decotigny. 12) Introduce devlink, which can be used to configure port link types (ethernet vs Infiniband, etc.), port splitting, and switch device level attributes as a whole. From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload". Basically, for a tunneled packet the checksum of the outer header is 'constant' (because with the checksum field filled into the inner protocol header, the payload of the outer frame checksums to 'zero'), and we can take advantage of that in various ways.

Pull cgroup updates from Tejun Heo: "cgroup changes for v4.6-rc1. No userland visible behavior changes in this pull request. I'll send out a separate pull request for the addition of cgroup namespace support. - The biggest change is the revamping of cgroup core task migration and controller handling logic. There are quite a few places where controllers and tasks are manipulated. Previously, many of those places implemented custom operations for each specific use case assuming specific starting conditions. While this worked, it makes the code fragile and difficult to follow. The bulk of this pull request restructures these operations so that most related operations are performed through common helpers which implement recursive (subtrees are always processed consistently) and idempotent (they make cgroup hierarchy converge to the target state rather than performing operations assuming specific starting conditions). This makes the code a lot easier to understand, verify and extend. - Implicit controller support is added. This is primarily for using perf_event on the v2 hierarchy so that perf can match cgroup v2 path without requiring the user to do anything special. The kernel portion of perf_event changes is acked but userland changes are still pending review. - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in certain environments. - There is a regression introduced during v4.4 devel cycle where attempts to migrate zombie tasks can mess up internal object management.

bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73 ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem. Given that RTNL is not always held, we need to use bond_for_each_slave_rcu().

MVNETA_BM has a dependency on MVNETA, so we can only select the former if the latter is enabled. However, the code dependency is the reverse: The mvneta module can call into the mvneta_bm module, so mvneta cannot be a built-in if mvneta_bm is a module, or we get a link error: drivers/net/built-in.o: In function `mvneta_remove': drivers/net/ethernet/marvell/mvneta.c:4211: undefined reference to `mvneta_bm_pool_destroy' drivers/net/built-in.o: In function `mvneta_bm_update_mtu': drivers/net/ethernet/marvell/mvneta.c:1034: undefined reference to `mvneta_bm_bufs_free' This avoids the problem by further clarifying the dependency so that MVNETA_BM is a silent Kconfig option that gets turned on by the new MVNETA_BM_ENABLE option.

There are two issues with the current code. First one is that we need to set res->class to 0 in case we use non-default classid matching. This is important for the case where cls_bpf was initially set up with an optional binding to a default class with tcf_bind_filter(), where the underlying qdisc implements bind_tcf() that fills res->class and tests for it later on when doing the classification. Convention for these cases is that after tc_classify() was called, such qdiscs (atm, drr, qfq, cbq, hfsc, htb) first test class, and if 0, then they lookup based on classid. Second, there's a bug with da mode, where res->classid is only assigned a 16 bit minor, but it needs to expand to the full 32 bit major/minor combination instead, therefore we need to expand with the bound major. This is fine as classes belonging to a classful qdisc must share the same major.

Aaron Young says: ==================== ldmvsw: Add ldmvsw driver This series adds a new Logical Domains vSwitch (ldmvsw) driver. The ldmvsw driver code will live in the drivers/net/ethernet/sun/ directory and will operate on Oracle systems running SPARC Linux in a Logical Domains environment (typically in the control domain). The ldmvsw driver is very similar in function to the existing sunvnet driver. Ldmvsw creates a network interface for each "vsw-port" node found in the Machine Description (MD) of a service domain. These nodes correspond to ports on a vswitch created by the logical domains manager. The created network interface(s) can be used by bridge/vswitch software (such as the Linux bridge or Open vSwitch) to provide guest domain(s) with network interconnectivity or connectivity to a physical network. Here is a example diagram of ldmvsw driver usage in a logical domain environment to provide a guest domain with network connectivity to a physical NIC on the service domain: +----------------+ +----------------- | Service Domain | | Guest domain | | | | | | LinuxBridge | | | | | | | | | | NIC Ldmvsw | | Sunvnet | +----------------+ +----------------+ | | LDC | LAN ------------------------------ As stated, the sunvnet and ldmvsw drivers are _very_ similar in function. They both create network interface(s) to receive/transmit network traffic across LDC network channel(s). Since the driver is so similar in function to sunvnet, the approach will be as follows to integrate the driver and take advantage of common code: Patch #1: Split sunvnet.c driver into sunvnet.c and sunvnet_common.c Patch #2: Modify the sunvnet_common code and data structures to be compatible with both the sunvnet and ldmvsw drivers. Patch #3: Add the new ldmvsw.c driver code Patch #4: Checkpatch cleanup of the sunvnet/sunvnet_common code. NOTE - Patch#1 renames a file (sunvnet.h -> sunvnet_common.h). When generating the patches (using git format-patch), I had to use the --no-renames option otherwise patch#1 would NOT apply using 'patch -p1' - which as I understand is a requirement for patch acceptance. I wasn't sure if this is proper thing to do. Please advise if not. Thanks. v2 changes: * change all EXPORT_SYMBOL declarations to EXPORT_SYMBOL_GPL * remove inline attribute for external function port_is_up_common() * Give all exported/global funcs in sunvnet_common.c a 'sunvnet_' prefix to avoid kernel global namespace pollution/collisions * ldmvsw.c: Order local variable declarations from longest to shortest line * ldmvsw.c: register the netdevice after all supporting state is ready/setup. NOTE: The consensus at Oracle is that the following functions must be done AFTER register_netdev() - this is the same ordering currently used in the sunvnet driver: 1. sunvnet_port_add_txq_common() - needs registered netdev 2. napi_enable() - requires registered netdev 3. vio_port_up() - as soon as this function is called LDC handshake messages will come in which must be handled by the napi code. ==================== Signed-off-by: NDavid S.

Add ldmvsw.c driver Details: The ldmvsw driver very closely follows the sunvnet.c code and makes use of the sunvnet_common.c code for core functionality. A significant difference between sunvnet and ldmvsw driver is sunvnet creates a network interface for each vnet-port *parent* node in the MD while the ldmvsw driver creates a network interface for every vsw-port node in the Machine Description (MD). Therefore the netdev_priv() for sunvnet is a vnet structure while the netdev_priv() for ldmvsw is a vnet_port structure. Vnet_port structures allocated by ldmvsw have the vsw bit set. When finding the net_device associated with a port, the common code keys off this bit to use either the net_device found in the vnet_port or the net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in sunvnet_common.h). This scheme allows the common code to work with both drivers with minimal changes. Similar to Xen, network interfaces created by the ldmvsw driver will always have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and <port_id> are a unique handle/port pair assigned to the associated vsw-port node in the MD.

Modify sunvnet common code and data structures to be compatible with both sunvnet and ldmvsw drivers. Details: Sunvnet operates on "vnet-port" nodes which appear in the Machine Description (MD) in a guest domain. Ldmvsw operates on "vsw-port" nodes which appear in the MD of a service domain. A difference between the sunvnet driver and the ldmvsw driver is the sunvnet driver creates a network interface (i.e. a struct net_device) for every vnet-port *parent* "network" node. Several vnet-ports may appear under this common parent network node - each corresponding to a common parent network interface. Conversely, since bridge/vswitch software will need to interface with every vsw-port in a system, the ldmvsw driver creates a network interface (i.e. a struct net_device) for every vsw-port - not every parent node as with sunvnet. This difference required some special handling in the common code as explained below. There are 2 key data structures used by the sunvnet and ldmvsw drivers (which are now found in sunvnet_common.h): 1. struct vnet_port This structure represents a vnet-port node in sunvnet and a vsw-port in the ldmvsw driver. 2. struct vnet This structure represents a parent "network" node in sunvnet and a parent "virtual-network-switch" node in ldmvsw. Since the sunvnet driver allocates a net_device for every parent "network" node, a net_device member appears in the struct vnet. Since the ldmvsw driver allocates a net_device for every port, a net_device member was added to the vnet_port. The common code distinguishes which structure net_device member to use by checking a 'vsw' bit that was added to the vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in sunvnet_common.h. The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv() in ldmvsw is a vnet_port. Therefore, any place in the common code where a netdev_priv() call was made, a wrapper function was implemented in each driver to first get the vnet and/or vnet_port (in a driver specific way) and pass them as newly added parameters to the common functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()). Since these wrapper functions call __tx_port_find(), __tx_port_find() was moved from the common code back into sunvnet.c. Note - ldmvsw.c does not require this function. These changes also required that port_is_up() be made into a common function and thus it was given a _common suffix and exported like the other common functions. A wrapper function was also added for vnet_start_xmit_common() to pass a driver-specific function arg to return the port associated with a given struct sk_buff and struct net_device. This was required because vnet_start_xmit_common() grabs a lock prior to getting the associated port. Using a function pointer arg allowed the code to work unchanged without risking changes to the non-trivial locking logic in vnet_start_xmit_common().

Split sunvnet.c into sunvnet.c and sunvnet_common.c. Details: Since the sunvnet and ldmvsw drivers will both use common sunvnet code, move the functions (and support functions) anticipated to be common code from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to sunvnet_common.h. The sunvnet_common.c code will be compiled into the kernel and act as a library of functions that are linked by either (or both) drivers when loaded. Function names for external functions in sunvnet_common.c (to be called by both the sunvnet and ldmvsw drivers) were tagged with a "_common" suffix to clearly designate them as common functions. No functional changes as of yet... just moved code verbatim to the new sunvnet_common.c/h files. Makefile/Kconfig support added to build sunvnet_common.c file. The code is included in the kernel if SUN_LDOMS is defined/selected. NOTE - per the SubmittingPatches documentation, since the code was just moved from one file another, the code was NOT checkpatch'd in this commit to aid in review.

Not all adapters have FC-NPIV configured. If bnx2fc is used with such an adapter, driver would read irrelevant data from the the nvram and log "FC-NPIV table with bad length..." In system logs. Simply accept that reading '0' as the feature offset in nvram indicates the feature isn't there and return.
