It seems on 32 bit kernels page_address() can reutrn a NULL value in some circumstances, and the pci_map_single api isn't prepared to handle that (on this system it results in a bogus pointer deference in nommu_map_page. The fix is pretty easy, if we convert the 3c59x driver to use the more convieient skb_frag_dma_map api we don't need to find the virtual address of the page at all, and page gets mapped to the hardware properly.

* net-timestamp: only report sw timestamp if reporting bit is setWillem de Bruijn2014-09-062-5/+2
| | | | | | | | | | | | | | | | | | | The timestamping API has separate bits for generating and reporting timestamps. A software timestamp should only be reported for a packet when the packet has the relevant generation flag (SKBTX_..) set and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set. The second check was accidentally removed. Reinstitute the original behavior. Tested: Without this patch, Documentation/networking/txtimestamp reports timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set. After the patch, it only reports them when the flag is set.

Without this patch for Kconfig, there's a superfluous dependency between NAT and x_tables. 2) Allow to use 0 in the cgroup match, the kernel rejects with -EINVAL with no good reason. From Daniel Borkmann. 3) Select CONFIG_NF_NAT from the nf_tables NAT expression, this also resolves another NAT dependency with x_tables. 4) Use HAVE_JUMP_LABEL instead of CONFIG_JUMP_LABEL in the Netfilter hook code as elsewhere in the kernel to resolve toolchain problems, from Zhouyi Zhou. 5) Use iptunnel_handle_offloads() to set up tunnel encapsulation depending on the offload capabilities, reported by Alex Gartrell patch from Julian Anastasov. 6) Fix wrong family when registering the ip_vs_local_reply6() hook, also from Julian. 7) Select the NF_LOG_* symbols from NETFILTER_XT_TARGET_LOG. Rafał Miłecki reported that when jumping from 3.16 to 3.17-rc, his log target is not selected anymore due to changes in the previous development cycle to accomodate the full logging support for nf_tables. ==================== Signed-off-by: David S.

| * netfilter: move NAT Kconfig switches out of the iptables scopePablo Neira Ayuso2014-08-185-57/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the NAT configs depend on iptables and ip6tables. However, users should be capable of enabling NAT for nft without having to switch on iptables. Fix this by adding new specific IP_NF_NAT and IP6_NF_NAT config switches for iptables and ip6tables NAT support. I have also moved the original NF_NAT_IPV4 and NF_NAT_IPV6 configs out of the scope of iptables to make them independent of it. This patch also adds NETFILTER_XT_NAT which selects the xt_nat combo that provides snat/dnat for iptables. We cannot use NF_NAT anymore since nf_tables can select this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hosts can be both little and big endian. In certain scenarios a big endian kernel can kexec a little endian kernel. This patch fixes this case from both ends: 1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown). 2) Do not rely on HW reset values when loading driver in little endian kernel but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When qeth device is queried for ethtool data, hardware operation is performed to extract the necessary information from the card. If the card is not online at the moment (e.g. it is undergoing recovery), this operation produces undesired effects like temporarily freezing the system. This patch prevents execution of the hardware query operation when the card is not online. In such case, ioctl() operation returns error with errno ENODEV.

First, if ifup (tg3_open) is called between tg3_io_error_detected() and tg3_io_resume() then tp->timer is armed twice before expiry. Once during tg3_open() and again during tg3_io_resume(). This results in BUG at kernel/time/timer.c:945. Second, if ifdown (tg3_close) is called between tg3_io_error_detected() and tg3_io_resume() then tg3_napi_disable() is called twice without a tg3_napi_enable between. Once during tg3_io_error_detected() and again during tg3_close().
