Under load, there an internal FIFO can overflow on the 5719. The fix is to scale back the PCIe maximum read request size based on the current link speed and width. Signed-off-by:

The APE needs certain bits in the mac_mode register to be enabled for traffic to flow correctly. This patch changes the code to always enable these bits in the presence of the APE. Signed-off-by:

The SELinux ip postroute code indicates when policy rejected a packet and passes the error back up the stack. The compat code does not. This patch sends the same kind of error back up the stack in the compat code. Based-on-patch-by:

Some of the SELinux netlink code returns a fatal error when the error might actually be transient. This patch just silently drops packets on potentially transient errors but continues to return a permanant error indicator when the denial was because of policy. Based-on-comments-by:

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. Signed-off-by:

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. Note : Before exiting from pktgen_thread_worker(), we must make sure kthread_stop() is waiting for this thread to be stopped, like its done in kernel/softirq.c Signed-off-by:

At compile time, we can replace the DIV_K instruction (divide by a constant value) by a reciprocal divide. At exec time, the expensive divide is replaced by a multiply, a less expensive operation on most processors. Signed-off-by:

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 57fe93b3 (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:
