* net: Use skb accessors in network coreMatthew Wilcox (Oracle)2019-07-226-32/+38
| | | | | | | | | In preparation for unifying the skb_frag and bio_vec, use the fine accessors which already exist and use skb_frag_t instead of struct skb_frag_struct. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* r8169: improve rtl_rxHeiner Kallweit2019-07-221-28/+15
| | | | | | | | | | | | | | This patch improves few aspects of rtl_rx, no functional change intended. 1. inline rtl8169_try_rx_copy 2. make pkt_size unsigned 3. use constant ETH_FCS_LEN instead of value 4 4. We just created the skb, so we don't need the checks in skb_put. Also we don't need the return value of skb_put. Set skb->tail and skb->len directly.

| | | | | | | | | | | | | | | | | | | | | | | This is trivial since we already have support for the entirely identical (from the kernel's point of view) RDNSS and DNSSL that also contain opaque data that needs to be passed down to userspace. As specified in RFC7710, Captive Portal option contains a URL. 8-bit identifier of the option type as assigned by the IANA is 37. This option should also be treated as userland. Hence, treat ND option 37 as userland (Captive Portal support) See: https://tools.ietf.org/html/rfc7710 https://www.iana.org/assignments/icmpv6-parameters/icmpv6-parameters.xhtml Fixes: e35f30c131a56 Signed-off-by: Maciej Żenczykowski <maze@google.com> Cc: Lorenzo Colitti <lorenzo@google.com> Cc: Remin Nguyen Van <reminv@google.com> Cc: Alexey I.

| * sched/rt, Kconfig: Unbreak def/oldconfig with CONFIG_PREEMPT=yThomas Gleixner2019-07-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on the preemption mode choice wich defaults to NONE. This also affects oldconfig builds. So rather than changing 114 defconfig files and being an annoyance to users, revert the rename and select a new config symbol PREEMPTION. That keeps everything working smoothly and the revelant ifdef's are going to be fixed up step by step.

Expected sequence of events is: CPU 0 CPU 1 ------------------------------------------------ exit_notify do_notify_parent do_notify_pidfd tsk->exit_state = EXIT_DEAD pidfd_poll if (tsk->exit_state) However nothing prevents the following sequence: CPU 0 CPU 1 ------------------------------------------------ exit_notify do_notify_parent do_notify_pidfd pidfd_poll if (tsk->exit_state) tsk->exit_state = EXIT_DEAD This causes a polling task to wait forever, since poll blocks because exit_state is 0 and the waiting task is not notified again. A stress test continuously doing pidfd poll and process exits uncovered this bug. To fix it, we make sure that the task's exit_state is always set before calling do_notify_pidfd.

If NODATASUM or NODATACOW set, we should not compress the extent. Normally NODATACOW is detected properly in run_delalloc_range() so compression won't happen for NODATACOW. However for NODATASUM we don't have any check, and it can cause compressed extent without csum pretty easily, just by: mkfs.btrfs -f $dev mount $dev $mnt -o nodatasum touch $mnt/foobar mount -o remount,datasum,compress $mnt xfs_io -f -c "pwrite 0 128K" $mnt/foobar And in fact, we have a bug report about corrupted compressed extent without proper data checksum so even RAID1 can't recover the corruption. (https://bugzilla.kernel.org/show_bug.cgi?id=199707) Running compression without proper checksum could cause more damage when corruption happens, as compressed data could make the whole extent unreadable, so there is no need to allow compression for NODATACSUM. The fix will refactor the inode compression check into two parts: - inode_can_compress() As the hard requirement, checked at btrfs_run_delalloc_range(), so no compression will happen for NODATASUM inode at all. - inode_need_compress() As the soft requirement, checked at btrfs_run_delalloc_range() and compress_file_range().

This patch allows the first and last skb in retransmit queue to be split even if memory limits are hit. It also adds the some room due to the fact that tcp_sendmsg() and tcp_sendpage() might overshoot sk_wmem_queued by about one full TSO skb (64KB size).

Case: 1) igb driver from intel. 2) Packet size is greater then 255. 3) MPLS forwards to VRF device. So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound() functions.

Add some synchronization between the two.

Both the flow_offload infrastructure and OVS define the flow_stats structure. Patch 3/4 in this batch indirectly pulls in the flow_stats definition from include/net/flow_offload.h into OVS, leading to structure redefinition compile-time errors. 2) Remove netns parameter from flow_block_cb_alloc(), this is not required as Jiri suggests. The flow_block_cb_is_busy() function uses the per-driver block list to check for used blocks which was the original intention for this parameter. 3) Rename tc_setup_cb_t to flow_setup_cb_t. This callback is not exclusive of tc anymore, this might confuse the reader as Jiri suggests, fix this semantic inconsistency. Add #include <linux/list.h> to include/net/netfilter/nf_tables_offload.h to avoid a compile break with CONFIG_HEADER_TEST=y. 4) Fix block sharing feature: Add flow_block structure and use it, update flow_block_cb_lookup() to use this flow_block object. ==================== Signed-off-by: David S.

This breaks compilation since OVS codebase includes net/sock.h which pulls in linux/filter.h which includes net/sch_generic.h. In file included from ./include/net/sch_generic.h:18:0, from ./include/linux/filter.h:25, from ./include/net/sock.h:59, from ./include/linux/tcp.h:19, from net/openvswitch/datapath.c:24 This definition takes precedence on OVS since it is placed in the networking core, so rename flow_stats in OVS to sw_flow_stats since this structure is contained in sw_flow.
