2018-07-16net: convert gro_count to bitmaskLi RongQing
gro_hash size is 192 bytes, and uses 3 cache lines, if there is few flows, gro_hash may be not fully used, so it is unnecessary to iterate all gro_hash in napi_gro_flush(), to occupy unnecessary cacheline. convert gro_count to a bitmask, and rename it as gro_bitmask, each bit represents a element of gro_hash, only flush a gro_hash element if the related bit is set, to speed up napi_gro_flush(). and update gro_bitmask only if it will be changed, to reduce cache update Suggested-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Li RongQing <lirongqing@baidu.com> Cc: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: David S.

2018-07-16ipv4/igmp: init group mode as INCLUDE when join source groupHangbin Liu
Based on RFC3376 5.1 If no interface state existed for that multicast address before the change (i.e., the change consisted of creating a new per-interface record), or if no state exists after the change (i.e., the change consisted of deleting a per-interface record), then the "non-existent" state is considered to have a filter mode of INCLUDE and an empty source list. Which means a new multicast group should start with state IN(). Function ip_mc_join_group() works correctly for IGMP ASM(Any-Source Multicast) mode. It adds a group with state EX() and inits crcount to mc_qrv, so the kernel will send a TO_EX() report message after adding group. But for IGMPv3 SSM(Source-specific multicast) JOIN_SOURCE_GROUP mode, we split the group joining into two steps. First we join the group like ASM, i.e. via ip_mc_join_group(). So the state changes from IN() to EX(). Then we add the source-specific address with INCLUDE mode. So the state changes from EX() to IN(A). Before the first step sends a group change record, we finished the second step. So we will only send the second change record. i.e. TO_IN(A). Regarding the RFC stands, we should actually send an ALLOW(A) message for SSM JOIN_SOURCE_GROUP as the state should mimic the 'IN() to IN(A)' transition. The issue was exposed by commit a052517a8ff65 ("net/multicast: should not send source list records when have filter mode change"). Before this change, we used to send both ALLOW(A) and TO_IN(A). After this change we only send TO_IN(A). Fix it by adding a new parameter to init group mode. Also add new wrapper functions so we don't need to change too much code. v1 -> v2: In my first version I only cleared the group change record. But this is not enough. Because when a new group join, it will init as EXCLUDE and trigger an filter mode change in ip/ip6_mc_add_src(), which will clear all source addresses' sf_crcount. This will prevent early joined address sending state change records if multi source addressed joined at the same time. In v2 patch, I fixed it by directly initializing the mode to INCLUDE for SSM JOIN_SOURCE_GROUP. I also split the original patch into two separated patches for IPv4 and IPv6.

2018-07-16mm: don't do zero_resv_unavail if memmap is not allocatedPavel Tatashin
Moving zero_resv_unavail before memmap_init_zone(), caused a regression on x86-32. The cause is that we access struct pages before they are allocated when CONFIG_FLAT_NODE_MEM_MAP is used. free_area_init_nodes() zero_resv_unavail() mm_zero_struct_page(pfn_to_page(pfn)); <- struct page is not alloced free_area_init_node() if CONFIG_FLAT_NODE_MEM_MAP alloc_node_mem_map() memblock_virt_alloc_node_nopanic() <- struct page alloced here On the other hand memblock_virt_alloc_node_nopanic() zeroes all the memory that it returns, so we do not need to do zero_resv_unavail() here.

2018-07-16drivers: core: Remove glue dirs from sysfs earlierBenjamin Herrenschmidt
For devices with a class, we create a "glue" directory between the parent device and the new device with the class name. This directory is never "explicitely" removed when empty however, this is left to the implicit sysfs removal done by kobject_release() when the object loses its last reference via kobject_put(). This is problematic because as long as it's not been removed from sysfs, it is still present in the class kset and in sysfs directory structure. The presence in the class kset exposes a use after free bug fixed by the previous patch, but the presence in sysfs means that until the kobject is released, which can take a while (especially with kobject debugging), any attempt at re-creating such as binding a new device for that class/parent pair, will result in a sysfs duplicate file name error. This fixes it by instead doing an explicit kobject_del() when the glue dir is empty, by keeping track of the number of child devices of the gluedir. This is made easy by the fact that all glue dir operations are done with a global mutex, and there's already a function (cleanup_glue_dir) called in all the right places taking that mutex that can be enhanced for this. It appears that this was in fact the intent of the function, but the implementation was wrong.

Disabling SCC before selecting to HS if selection of HS400 has occurred. This can be done in an implementation of prepare_hs400_tuning_downgrade 2. Updating registers after switching to HS400 This can be done in an implementation of complete_hs400_tuning If hs400_downgrade or hs400_complete are not implemented then they are not called.

2018-07-16mmc: core: Adjust and reuse the macro of R1_STATUS(x)Shawn Lin
R1_STATUS(x) now is only used by ioctl_rpmb_card_status_poll(), which checks all bits as possible. But according to the spec, bit 17 and bit 18 should be ignored, as well bit 14 which is reserved(must be set to 0) quoting from the spec and these rule apply to all places checking the device status. So change its checking from 0xFFFFE000 to 0xFFF9A000. As a bonus, we reuse it for mmc_do_erase() as well as mmc_switch_status_error(). (1) Currently mmc_switch_status_error() doesn't check bit 25, but it means device is locked but not unlocked by CMD42 prior to any operations which need check busy, which is also not allowed. (2) mmc_do_erase() also forgot to to check bit 15, WP_ERASE_SKIP. The spec says "Only partial address space was erased due to existing write protected blocks.", which obviously means we should fail this I/O. Otherwise, the partial erased data stored in nonvalatile flash violates the data integrity from the view of I/O owner, which probably confuse it when further used. So reusing R1_STATUS for them not only improve the readability but also slove real problems. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2018-07-16efi: Use a work queue to invoke EFI Runtime ServicesSai Praneeth
Presently, when a user process requests the kernel to execute any UEFI runtime service, the kernel temporarily switches to a separate set of page tables that describe the virtual mapping of the UEFI runtime services regions in memory. Since UEFI runtime services are typically invoked with interrupts enabled, any code that may be called during this time, will have an incorrect view of the process's address space. Although it is unusual for code running in interrupt context to make assumptions about the process context it runs in, there are cases (such as the perf subsystem taking samples) where this causes problems. So let's set up a work queue for calling UEFI runtime services, so that the actual calls are made when the work queue items are dispatched by a work queue worker running in a separate kernel thread. Such threads are not expected to have userland mappings in the first place, and so the additional mappings created for the UEFI runtime services can never clash with any. The ResetSystem() runtime service is not covered by the work queue handling, since it is not expected to return, and may be called at a time when the kernel is torn down to the point where we cannot expect work queues to still be operational. The non-blocking variants of SetVariable() and QueryVariableInfo() are also excluded: these are intended to be used from atomic context, which obviously rules out waiting for a completion to be signalled by another thread. Note that these variants are currently only used for UEFI runtime services calls that occur very early in the boot, and for ones that occur in critical conditions, e.g., to flush kernel logs to UEFI variables via efi-pstore.

Add the initial support for Coresight Address Translation Unit, which augments the TMC in Coresight SoC-600 by providing an improved Scatter Gather mechanism.

Add a new coresight device type, which do not belong to any of the existing types, i.e, source, sink, link etc. A helper device could be connected to a coresight device, which could augment the functionality of the coresight device. This is intended to cover Coresight Address Translation Unit (CATU) devices, which provide improved Scatter Gather mechanism for TMC ETR. The idea is that the helper device could be controlled by the driver of the device it is attached to (in this case ETR), transparent to the generic coresight driver (and paths). The operations include enable(), disable(), both of which could accept a device specific "data" which the driving device and the helper device could share. Since they don't appear in the coresight "path" tracked by software, we have to ensure that they are powered up/down whenever the master device is turned on.

For the latter in particular, it uses the reciprocal algorithm to emulate it, from Jiong. 4) Add BTF pretty print functionality to bpftool in plain and JSON output format, from Okash. 5) Add build and installation to the BPF helper man page into bpftool, from Quentin. 6) Add a TCP BPF callback for listening sockets which is triggered right after the socket transitions to TCP_LISTEN state, from Andrey. 7) Add a new cgroup tree command to bpftool which iterates over the whole cgroup tree and prints all attached programs, from Roman. 8) Improve xdp_redirect_cpu sample to support parsing of double VLAN tagged packets, from Jesper. ==================== Signed-off-by: David S.

2018-07-13net: ipmr: add support for passing full packet on wrong vifNikolay Aleksandrov
This patch adds support for IGMPMSG_WRVIFWHOLE which is used to pass full packet and real vif id when the incoming interface is wrong. While the RP and FHR are setting up state we need to be sending the registers encapsulated with all the data inside otherwise we lose it. The RP then decapsulates it and forwards it to the interested parties. Currently with WRONGVIF we can only be sending empty register packets and will lose that data. This behaviour can be enabled by using MRT_PIM with val == IGMPMSG_WRVIFWHOLE. This doesn't prevent IGMPMSG_WRONGVIF from happening, it happens in addition to it, also it is controlled by the same throttling parameters as WRONGVIF (i.e. 1 packet per 3 seconds currently). Both messages are generated to keep backwards compatibily and avoid breaking someone who was enabling MRT_PIM with val == 4, since any positive val is accepted and treated the same.

2018-07-13xdp: support simultaneous driver and hw XDP attachmentJakub Kicinski
Split the query of HW-attached program from the software one. Introduce new .ndo_bpf command to query HW-attached program. This will allow drivers to install different programs in HW and SW at the same time. Netlink can now also carry multiple programs on dump (in which case mode will be set to XDP_ATTACHED_MULTI and user has to check per-attachment point attributes, IFLA_XDP_PROG_ID will not be present). We reuse IFLA_XDP_PROG_ID skb space for second mode, so rtnl_xdp_size() doesn't need to be updated. Note that the installation side is still not there, since all drivers currently reject installing more than one program at the time.

2018-07-13xdp: don't make drivers report attachment modeJakub Kicinski
prog_attached of struct netdev_bpf should have been superseded by simply setting prog_id long time ago, but we kept it around to allow offloading drivers to communicate attachment mode (drv vs hw). Subsequently drivers were also allowed to report back attachment flags (prog_flags), and since nowadays only programs attached will XDP_FLAGS_HW_MODE can get offloaded, we can tell the attachment mode from the flags driver reports. Remove prog_attached member.

2018-07-13cpu/hotplug: Set CPU_SMT_NOT_SUPPORTED earlyThomas Gleixner
The CPU_SMT_NOT_SUPPORTED state is set (if the processor does not support SMT) when the sysfs SMT control file is initialized. That was fine so far as this was only required to make the output of the control file correct and to prevent writes in that case. With the upcoming l1tf command line parameter, this needs to be set up before the L1TF mitigation selection and command line parsing happens.
