This commit is same in nature as v2.6.37-rc1-755-g3654654f; the network namespace itself is not modified when calling net_generic, so the parameter can be const. Signed-off-by:

Add multiqueue support to vmxnet3 driver This change adds multiqueue and thus receive side scaling support to vmxnet3 device driver. Number of rx queues is limited to 1 in cases where MSI is not configured or one MSIx vector is not available per rx queue 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:

GCC (rightfully) complains that: drivers/atm/fore200e.c:614:5: warning: operation on 'cmdq->head' may be undefined This is due to the FORE200E_NEXT_ENTRY macro, which essentially evaluates to: i = ++i % m Make it what's explicitly intended here which is: i = (i + 1) % m and the warning goes away.

IFLA_PROTINFO exposes timer related per device settings in jiffies. Change it to expose these values in msecs like the sysctl interface does. I did not find any users of IFLA_PROTINFO which rely on any of these values and even if there are, they are likely already broken because there is no way for them to reliably convert such a value to another time format.

Since repeating u16 value to u8 value conversion using switch() clause's case statement is wasteful, this patch introduces u16 to u8 mapping table and removes most of case statements. As a result, the size of net/core/filter.o is reduced by about 29% on x86. Signed-off-by:

netif_set_real_num_rx_queues() can decrement and increment the number of rx queues. For example ixgbe does this as features and offloads are toggled. Presumably this could also happen across down/up on most devices if the available resources changed (cpu offlined). The kobject needs to be zero'd in this case so that the state is not preserved across kobject_put()/kobject_init_and_add(). This resolves the following error report. ixgbe 0000:03:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX kobject (ffff880324b83210): tried to init an initialized object, something is seriously wrong.

RCU conversion in IGMP code done in net-next-2.6 raised a race in __bond_resend_igmp_join_requests(). It iterates in_dev->mc_list without appropriate protection (RTNL, or read_lock on in_dev->mc_list_lock). Another cpu might delete an entry while we use it and trigger a fault. Signed-off-by:

snprintf() returns number of bytes that were copied if there is no overflow. This code uses return value as number of copied bytes. Theoretically format string '%lu.%09lu %pI4:%u %pI4:%u %d %#x %#x %u %u %u %u\n' may be expanded up to 163 bytes. In reality tv.tv_sec is just few bytes instead of 20, 2 ports are just 5 bytes each instead of 10, length is 5 bytes instead of 10. The rest is an unstrusted input. Theoretically if tv_sec is big then copy_to_user() would overflow tbuf. tbuf was increased to fit in 163 bytes. snprintf() is used to follow return value semantic. Signed-off-by:
