Kernel automatically creates a tp for each (kind, protocol, priority) tuple, which has handle 0, when we add a new filter, but it still is left there after we remove our own, unless we don't specify the handle (literally means all the filters under the tuple). For example this one is left: # tc filter show dev eth0 filter parent 8001: protocol arp pref 49152 basic The user-space is hard to clean up these for kernel because filters like u32 are organized in a complex way. So kernel is responsible to remove it after all filters are gone. Each type of filter has its own way to store the filters, so each type has to provide its way to check if all filters are gone.

According to RFC3032 section 2.4.2 packets with an outgoing ttl of 0 MUST NOT be forwarded. According to section 2.4.1 an outgoing TTL of 0 comes from an incomming TTL <= 1. Therefore any packets that is received with a ttl <= 1 should not have it's ttl decremented and forwarded. Signed-off-by:

Sparse was generating a lot of warnings mostly from missing annotations in the code. Add missing annotations and in a few cases tweak the code for performance by moving work before loops. This also fixes a problematic ommision of rcu_assign_pointer and rcu_dereference. Hopefully with complete rcu annotations any new rcu errors will stick out like a sore thumb. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-03-07 This series contains updates to i40e and i40evf only. Most notably, Greg provides the patch to remove the dreaded configfs changes in the driver. Shannon cleans up a sparse warning by simply straighting out the code so it is less convoluted. Fixes an issue where the vector allocation was trying too hard to save vectors for VMDq, to the point of not giving the PF enough when in a tight situation, such as an NPAR partition. Changed the driver to make sure that the PF will get all the queues and vectors it wants to fill out its destiny. Cleans up reporting to only print the port and VEB stats if it is the first partition of a multiplexed port. Catherine cleans up some duplicated code by simply removing the duplicate code. Kamil cleans up the driver by removing an un-needed endian conversion because it is already done by a register read function. Jesse fixes a variable width of a datatype, where a u16 should have been a u32. Also cleans up debug_read_register() to resolve some sparse warnings. Updates the driver to use prefetch() to get the next Tx descriptor, like in ixgbe, to improve performance. Akeem moves around code to enable/disable loopback so that other non-SRIOV supported driver functions can take advantage of the changes. Anjali cleans up the logging for adding/deleting FD-SB filters, since ethtool shows all the filters on an interface. Updates the driver to use l4_tunnel type generically to keep code flow simple. Simplifies the RSS code since the driver initializes the rss_size_max in sw_init. ==================== Signed-off-by: -

In preparation for supporting multiple Rx queues: 1. Move the initialization of priv->num_rx_bds, priv->rx_bds, and priv->rx_cbs from bcmgenet_init_rx_ring() to bcmgenet_init_dma() since they are not specific to a single Rx queue. Mimics the Tx init model where priv->num_tx_bds, priv->tx_bds, and priv->tx_cbs are initialized in bcmgenet_init_dma(). 2. Program DMA_MBUF_DONE_THRESH = 1 so that future Rx queues Q0-Q15 will get per-packet Rx interrupt. 3. Group DMA_START_ADDR, RDMA_READ_PTR, RDMA_WRITE_PTR, and DMA_END_ADDR initialization together. Mimics the Tx init model. 4. There is 1-to-1 mapping between RxCBs and RxBDs. Precalculate RxCB->bd_addr so that it can be used in the future. Signed-off-by:

Merge branch 'macb-next' Boris Brezillon says: ==================== net/macb: merge at91_ether driver into macb driver The rm9200 boards use the dedicated at91_ether driver instead of the regular macb driver. Both the macb and at91_ether drivers can be compiled as separated modules. Since the at91_ether driver uses code from the macb driver, at91_ether.ko depends on macb.ko. However the macb.ko module always fails to load on rm9200 boards: the macb_probe() function expects a hclk clock which doesn't exist on rm9200. Then the at91_ether.ko can't be loaded in turn due to unresolved dependencies. This series of patches fix this issue by merging at91_ether into macb. Patch 1 is fixing a problem that might happen when enabling ARM multi-platform suppot. Changes since v3: - move "net: macb: remove #if defined(CONFIG_ARCH_AT91) sections" patch into this series to avoid dependency on other patch series. Changes since v2: - rebase after changed brought by commit "net: macb: remove #if defined(CONFIG_ARCH_AT91) sections" Changes since v1: - rework probe functions to share common probing logic ==================== Signed-off-by: -
Cyrille Pitchen authored
macb and at91_ether drivers can be compiled as modules, but the at91_ether driver use some functions and variables defined in the macb one, thus creating a dependency on the macb driver. Since these drivers are sharing the same logic we can easily merge at91_ether into macb. In order to factorize common probing logic we've added an ->init() function to struct macb_config (the structure associated with the compatible string), and moved macb specific init code from macb_probe to macb_init.

Most of the functions from the Common Clk Framework handle NULL pointer as input argument. Since the TX clock is optional, we now set tx_clk to NULL value instead of ERR_PTR(-ENOENT) when this clock is not available. This simplifies the clock management and avoid the need to test tx_clk value. Signed-off-by:

With multi platform support those sections could lead to unexpected behavior if both ARCH_AT91 and another ARM SoC using the MACB IP are selected. Add two new capabilities to encode the default MII mode and the presence of a CLKEN bit in USRIO register. Then define the appropriate config for IPs embedded in at91 SoCs. Signed-off-by:

Since GLQF_FDCNT_0 register now has the right offset, use it to simplify our FD flush flow. If the filter add error happens to be for SB we just auto disable SB. If filter error happens to be for ATR, auto disable ATR and mark the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes. If we are entering flush too quickly (< 30 seconds) and we have quite a few SB rules, its time to disable ATR for good. Since SB + ATR rules is most likely making the FD table unstable. ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off) and will remain off after turning ntuple on till it gets unstable again.

It is not necessary to print FD filter add/delete log with normal debug settings because ethtool -n ethx shows all the FD-SB filters on an interface. The log can still be turned on through higher debug levels and it will continue to print a log if there was an error in the add/delete process.

The initial problem solved here is that the vector allocation was trying too hard to save vectors for VMDq, to the point of not giving the PF enough when in a tight situation such as an NPAR partition. This change makes sure that the PF will get all the queues and vectors it wants to fill out its destiny. Essentially, nothing is specially reserved for VMDq, it simply gets whatever is left after the PF, FCoE, and FD sideband get what they want. Additionally, the calculations for the reservations were harder to follow than necessary, so I've made it more straight forward. Change-ID: I99b384f104535b686c690b8ef0a787559485c8d4 Signed-off-by:

Fengguang reported, that on openrisc and avr32 architectures, we get the following linker errors on *_defconfig builds that have no bpf syscall support: net/built-in.o:(.rodata+0x1cd0): undefined reference to `bpf_map_lookup_elem_proto' net/built-in.o:(.rodata+0x1cd4): undefined reference to `bpf_map_update_elem_proto' net/built-in.o:(.rodata+0x1cd8): undefined reference to `bpf_map_delete_elem_proto' Fix it up by providing built-in weak definitions of the symbols, so they can be overridden when the syscall is enabled. I think the issue might be that gcc is not able to optimize all that away. This patch fixes the linker errors for me, tested with Fengguang's make.cross [1] script.
