2010-11-24ipv6: mcast: RCU conversionEric Dumazet3-33/+47
ipv6_sk_mc_lock rwlock becomes a spinlock. readers (inet6_mc_check()) now takes rcu_read_lock() instead of read lock. Writers dont need to disable BH anymore. struct ipv6_mc_socklist objects are reclaimed after one RCU grace period. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-11-24stmmac: add init/exit callback in plat_stmmacenet_data structGiuseppe CAVALLARO3-30/+16
This patch adds in the plat_stmmacenet_data the init and exit callbacks that can be used for invoking specific platform functions. For example, on ST targets, these call the PAD manager functions to set PIO lines and syscfg registers. The patch removes the stmmac_claim_resource only used on STM Kernels as well.

Using dma_alloc_coherent() permits to use GFP_KERNEL allocations instead of GFP_ATOMIC ones.

2010-11-22macvlan: Introduce 'passthru' mode to takeover the underlying deviceSridhar Samudrala2-1/+33
With the current default 'vepa' mode, a KVM guest using virtio with macvtap backend has the following limitations. - cannot change/add a mac address on the guest virtio-net - cannot create a vlan device on the guest virtio-net - cannot enable promiscuous mode on guest virtio-net To address these limitations, this patch introduces a new mode called 'passthru' when creating a macvlan device which allows takeover of the underlying device and passing it to a guest using virtio with macvtap backend. Only one macvlan device is allowed in passthru mode and it inherits the mac address from the underlying device and sets it in promiscuous mode to receive and forward all the packets.

2010-11-21pktgen: allow faster module unloadEric Dumazet1-5/+12
Unloading pktgen module needs ~6 seconds on a 64 cpus machine, to stop 64 kthreads. Add a pktgen_exiting variable to let kernel threads die faster, so that kthread_stop() doesnt have to wait too long for them. This variable is not tested in fast path.

2010-11-19filter: optimize sk_run_filterEric Dumazet6-64/+61
Remove pc variable to avoid arithmetic to compute fentry at each filter instruction. Jumps directly manipulate fentry pointer. As the last instruction of filter[] is guaranteed to be a RETURN, and all jumps are before the last instruction, we dont need to check filter bounds (number of instructions in filter array) at each iteration, so we remove it from sk_run_filter() params. On x86_32 remove f_k var introduced in commit 57fe93b374a6b871 (filter: make sure filters dont read uninitialized memory) Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to avoid too many ifdefs in this code. This helps compiler to use cpu registers to hold fentry and A accumulator. On x86_32, this saves 401 bytes, and more important, sk_run_filter() runs much faster because less register pressure (One less conditional branch per BPF instruction) # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 2948 0 0 2948 b84 net/core/filter.o 3349 0 0 3349 d15 net/core/filter_pre.o on x86_64 : # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 5173 0 0 5173 1435 net/core/filter.o 5224 0 0 5224 1468 net/core/filter_pre.o Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: David S.
