* i40e/i40evf: Refactor i40e_debug_aq and make some functions staticShannon Nelson2015-03-076-54/+54
| | | | | | | | | | | | A sparse complaint in i40e_debug_aq in a funky buffer write goes away by straightening out the code out to something less convoluted. Also fix some other sparse warnings while we are at it, making some functions static and using NULL instead of 0.

* ebpf: bpf_map_*: fix linker error on avr32 and openrisc archDaniel Borkmann2015-03-071-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: gro: remove obsolete code from skb_gro_receive()Eric Dumazet2015-03-071-44/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers use copybreak to copy tiny frames into smaller skb, and this smaller skb might not have skb->head_frag set for various reasons. skb_gro_receive() currently doesn't allow to aggregate the smaller skb into the previous GRO packet if this GRO packet has at least 2 MSS in it. Following workload easily demonstrates the problem. netperf -t TCP_RR -H target -- -r 3000,3000 (tcpdump shows one GRO packet with 2 MSS, plus one additional packet of 104 bytes that should have been appended.) It turns out that we can remove code from skb_gro_receive(), because commit 8a29111c7ca6 ("net: gro: allow to build full sized skb") and its followups removed the assumption that a GRO packet with a frag_list had to have an empty head. Removing this code allows the aggregation of the last (incomplete) frame in some RPC workloads. Note that tcp_gro_receive() already takes care of forcing a flush if necessary, including this case. If we want to avoid using frag_list in the first place (in forwarding workloads for example, as the outgoing NIC is generally not able to cope with skbs having a frag_list), we need to address this separately.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alexander Duyck says: ==================== The rest of the FIB patches (add key_vector to fib_table) This patch series is the rest of what I had originally planned for this kernel release. It adds a structure called key_vector which is embedded within every tnode, leaf, and the trie root itself. By doing this we can navigate from any point within the trie to any other point fairly quickly and avoiding NULL pointer checks in the case of a backtrace. As a result we can pipeline things a bit further since we don't have to worry about dereferencing NULL in a backtrace. This can amount to significant savings on a long backtrace. I decided to drop the up-level code as that conflicts with combining the main and local tries. I have one patch as an RFC that currently combines the tries however it still needs some work as we have to split the local and main tries in the event of custom rules being defined. As such we are probably going to be doing some more hacking on fib_table_flush_external as that will also need to flush the local entries from the main trie and place them back in the local trie. v2: Rebased on the switchdev FIB offload work ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | This change makes it so that the root of the trie contains a key_vector, by doing this we make room to essentially collapse the entire trie by at least one cache line as we can store the information about the tnode or leaf that is pointed to in the root.

| * | bcma: gpio: enable GPIO IRQ domain on BCM5301XRafał Miłecki2015-03-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just like on BCM47XX arch, BCM5301X also has ChipCommon with IRQ for GPIOs. Now we have interrupts working on BCM5301X we can finally make use of it. This has been successfully tested on 5 different devices (Buffalo, Luxul, Netgear).

| * | ssb: Silence warning for unknown backplane revisionLarry Finger2015-03-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a BCM4318 in a PCMCIA format, I get a startup message that the device uses backplane revision 0xF000000. Next a WARNING is logged. Despite the message, the device works fine, This patch silences the warning.

| * | wil6210: increase cmd buffer size to avoid sscanf buffer overflowColin Ian King2015-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cppcheck detected a buffer overflow: [drivers/net/wireless/ath/wil6210/debugfs.c:634]: (error) Width 8 given in format string (no. 1) is larger than destination buffer 'cmd[8]', use %7s to prevent overflowing it. For the current %8s sscanf we require cmd to be 9 chars long so increase it by 1 byte to prevent the sscan overflow (rather than reduce the %8s specifier to %7s as cppcheck recommends).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ath9k_mci_update_rssi() is required only for cards that use MCI scheme. Make sure that it is not called for 3-wire cards. * Call ath9k_ps_wakeup() early since register accesses are made in ath9k_mci_update_rssi(). * Fix usage of btcoex_lock to handle no_stomp_timer.
