Convert ebtables to copying entries, matches and targets one by one. The solution is analogous to that of generic xt_(match|target)_to_user helpers, but is applied to different structs. Convert existing helpers ebt_make_XXXname helpers that overwrite fields of an already copy_to_user'd struct with ebt_XXX_to_user helpers that copy all relevant fields of the struct from scratch.

xt_entry_target, xt_entry_match and their private data may contain kernel data. Introduce helper functions xt_match_to_user, xt_target_to_user and xt_data_to_user that copy only the expected fields. These replace existing logic that calls copy_to_user on entire structs, then overwrites select fields. Private data is defined in xt_match and xt_target. All matches and targets that maintain kernel data store this at the tail of their private structure. Extend xt_match and xt_target with .usersize to limit how many bytes of data are copied. The remainder is cleared. If compatsize is specified, usersize can only safely be used if all fields up to usersize use platform-independent types. Otherwise, the compat_to_user callback must be defined. This patch does not yet enable the support logic. Signed-off-by:

implement sctp_error to let nf_conntrack_in validate crc32c on the packet transport header. Assign skb->ip_summed to CHECKSUM_UNNECESSARY and return NF_ACCEPT in case of successful validation; otherwise, return -NF_ACCEPT to let netfilter skip connection tracking, like other protocols do. Besides preventing corrupted packets from matching conntrack entries, this fixes functionality of REJECT target: it was not generating any ICMP upon reception of SCTP packets, because it was computing RFC 1624 checksum on the packet and systematically mismatching crc32c in the SCTP header.

nf_conntrack needs to compute crc32c when dealing with SCTP packets. Moreover, NF_NAT_PROTO_SCTP (currently selecting LIBCRC32C) can be enabled only if conntrack support for SCTP is enabled. Therefore, move enabling of kernel support for crc32c so that it is selected when NF_CT_PROTO_SCTP=y. Signed-off-by:

udplite was copied from udp, they are virtually 100% identical. This adds udplite tracker to udp instead, removes udplite module, and then makes the udplite tracker builtin. udplite will then simply re-use udp timeout settings. It makes little sense to add separate sysctls, nowadays we have fine-grained timeout policy support via the CT target. old: text data bss dec hex filename 1633 672 0 2305 901 nf_conntrack_proto_udp.o 1756 672 0 2428 97c nf_conntrack_proto_udplite.o 69526 17937 268 87731 156b3 nf_conntrack.ko new: text data bss dec hex filename 2442 1184 0 3626 e2a nf_conntrack_proto_udp.o 68565 17721 268 86554 1521a nf_conntrack.ko Signed-off-by:

Saeed Mahameed says: ==================== Mellanox mlx5 core and ODP updates 2017-01-01 The following eleven patches mainly come from Artemy Kovalyov who expanded mlx5 on-demand-paging (ODP) support. In addition there are three cleanup patches which don't change any functionality, but are needed to align codebase prior accepting other patches. Memory region (MR) in IB can be huge and ODP (on-demand paging) technique allows to use unpinned memory, which can be consumed and released on demand. This allows to applications do not pin down the underlying physical pages of the address space, and save from them need to track the validity of the mappings. Rather, the HCA requests the latest translations from the OS when pages are not present, and the OS invalidates translations which are no longer valid due to either non-present pages or mapping changes. In existing ODP implementation applications is needed to register memory buffers for communication, though registered memory regions need not have valid mappings at registration time. This patch set performs the following steps to expand current ODP implementation: 1. It refactors UMR to support large regions, by introducing generic function to perform HCA translation table modifications. This function supports both atomic and process contexts and is not limited by number of modified entries. This function allows to enable reallocated memory regions of arbitrary size, so adding MR cache buckets to support up to 16GB MRs. 2. It changes page fault event format and refactor page faults logic together with addition of atomic support. 3. It prepares mlx5 core code to support implicit registration with simplified and relaxed semantics. Implicit ODP semantics allows to applications provide special memory key that represents their complete address space. Thus all IO accesses referencing to this key (with proper access rights associated with the key) wouldn't need not register any virtual address range.

Update PAGE_FAULT_RESUME command layout. Three bit fields describing page fault: rdma, rdma_write, req_res gave 8 possible combinations, while only a few were legal. Now they are interpreted as three-bit type field, where former legal combinations turns into corresponding types and unused were added as new types. Signed-off-by:

* Update struct mlx5_wqe_umr_ctrl_seg. * Currenlty UMR send_flags aim only certain use cases: enabled/disable cached MR, modifying XLT for ODP. By making flags independent make UMR more flexible allowing arbitrary manipulations. * Since different UMR formats have different entry sizes UMR request should receive exact size of translation table update instead of number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr and update relevant code accordingly. * Add support of length64 bit. Signed-off-by:

This patch adds the following items to IFC file. 1. MLX5_MKC_ACCESS_MODE_KSM enum value for creating KSM memory keys. KSM access mode used when indirect MKey associated with fixed memory size entries. 2. null_mkey field that is used to indicate non-present KLM/KSM entries, where it causes the device to generate page fault event when trying to access it. 3. struct mlx5_ifc_cmd_hca_cap_bits capability bits indicating related value/field is supported: * fixed_buffer_size - MLX5_MKC_ACCESS_MODE_KSM * umr_extended_translation_offset - translation_offset_42_16 in UMR ctrl segment * null_mkey - null_mkey in QUERY_SPECIAL_CONTEXTS Signed-off-by: -

The order of features exposed by private mlx5-abi.h file is CQE zipping, packet pacing and multi-packet WQE. The internal order implemented in mlx5_ib_query_device() is multi-packet WQE, CQE zipping and packet pacing. Such difference hurts code readability, so let's sync, while mlx5-abi.h (exposed to userspace) is the primary order. This commit doesn't change any functionality. Signed-off-by:

For core revision 3.x Address-Aligned Beats is available in two registers. The DT property snps,aal was created for AAL in the DMA bus register, which is a read/write bit. The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode register, which is a read only bit that reflects the value of AAL in the DMA bus register. Since the value of snps,axi_all is never used in the driver, and since the property was created for a bit that is read only, it should be safe to remove the property. Acked-by:
