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. 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: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

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.

2010-11-18net: zero kobject in rx_queue_releaseJohn Fastabend1-2/+8
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().

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.

2010-11-178139cp: fix checksum brokenShan Wei1-6/+4
I am not family with RealTek RTL-8139C+ series 10/100 PCI Ethernet driver. I try to guess the meaning of RxProtoIP and IPFail. RxProtoIP stands for received IPv4 packet that upper protocol is not tcp and udp. !(status & IPFail) is true means that driver correctly to check checksum in IPv4 header. If these are right, driver will set ip_summed with CHECKSUM_UNNECESSARY for other upper protocol, e.g. sctp, igmp protocol. This will cause protocol stack ignores checksum check for packets with invalid checksum. This patch is only compile-test. Signed-off-by: Shan Wei <shanwei@cn.fujitsu.com> Signed-off-by: David S.
