Alexei Starovoitov says: ==================== BPF testsuite and cleanup This patchset adds BPF testsuite and improves readability of classic to internal BPF converter. The testsuite helped to find 'negative offset bug' in x64 JIT that was fixed by commit fdfaf64e ("x86: bpf_jit: support negative offsets") It can be very useful for classic and internal JIT compiler developers. Also it serves as performance benchmark. x86_64/i386 pass all tests with and without JIT. arm32 JIT is failing negative offset tests which are unsupported. Internal BPF tests are much larger than classic tests to cover different combinations of registers. Negative tests check correctness of classic BPF verifier which must reject them. ==================== Signed-off-by:

The testsuite covers classic and internal BPF instructions. It is particularly useful for JIT compiler developers. Adds to "net" selftest target. The testsuite can be used as a set of micro-benchmarks. It measures execution time of each BPF program in nsec. This patch adds core framework. Signed-off-by:

Introduce BPF helper macros to define instructions (similar to old BPF_STMT/BPF_JUMP macros) Use them while converting classic BPF to internal and in BPF testsuite later. Signed-off-by:

This revert commit efb842c4("sctp: optimize the sctp_sysctl_net_register"), Since it doesn't kmemdup a sysctl_table for init_net, so the init_net->sctp.sysctl_header->ctl_table_arg points to sctp_net_table which is a static array pointer. So when doing sctp_sysctl_net_unregister, it will free sctp_net_table, then we will get a NULL pointer dereference like that: [ 262.948220] BUG: unable to handle kernel NULL pointer dereference at 000000000000006c [ 262.948232] IP: [<ffffffff81144b70>] kfree+0x80/0x420 [ 262.948260] PGD db80a067 PUD dae12067 PMD 0 [ 262.948268] Oops: 0000 [#1] SMP [ 262.948273] Modules linked in: sctp(-) crc32c_generic libcrc32c ...

commit 6d48f44b "mdio_bus: implement devm_mdiobus_alloc/devm_mdiobus_free" introduced a new function devm_mdiobus_alloc_size() but added an export for a different function devm_mdiobus_alloc(), which was obviously a simple mistake that leads to build error whenever this function is used from a loadable module: ERROR: "devm_mdiobus_alloc_size" [drivers/net/ethernet/ti/davinci_mdio.ko] undefined!

Introduce a generic option store function for sysfs and remove the specific ones. The attribute name is used to match against the option which is to be set. Also adjust the "name" of tlb_dynamic_lb option to match the sysfs entry and fix the comments and comment style in bond_sysfs.c The comments which showed obvious behaviour (i.e. behaviour that's seen in the option's entry) are removed, the ones that explained important points about the setting function have been moved above the respective set function in bond_options.c There's only 1 exception: num_unsol_na/num_grat_arp since it has 2 names CC: Jay Vosburgh <j.vosburgh@gmail.com> CC: Veaceslav Falico <vfalico@gmail.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: David S.

Sathya Perla says: ==================== be2net: patch set This patch set contains the following modificatons: * three patches (1/7 to 3/7) that fix indentation style issues * convert the u8 vlan[] array to a bit-map to reduce memory usage * use MCCQ instead of MBOX in be_cmd_rss_config() as the MCCQ is already created by that time * include rx-comp-error counter in ethtool stats * remove the unused promiscuous setting from be_cmd_vlan_config() Pls apply to net-next tree. Thanks! ==================== Signed-off-by: -

be_cmd_rss_config() is called after the MCCQ is created; so this cmd is now modified to use the MCCQ instead of MBOX. Also fixed some indentation problem in this routine. Signed-off-by:

Rajesh Borundia says: ==================== qlcnic: SR-IOV and FW-dump enhancements This patch series contain following enhancements. * SR-IOV enhancements: - Allow SR-IOV VF's to probe in hypervisor. SR-IOV VF can be uplinked to bridge/macvtap device with this change. - Commands from VF are processed in process context as it may sleep during PF-VF communication. Earlier we use to process qlcnic_sriov_vf_set_multi function in process context but now we process individual commands. - As SR-IOV VF's can be uplinked to bridge/macvtap device support mac-learning to allow communication through embedded switch. * FW-dump enhancement: - Support to collect RDMEM section of firmware dump using PEX DMA method for 82xx series adapter. * Changes in v2: - Removed unnecessary cast from void pointer to something else and verified this issue in entire patch series as per David Miller's suggestion. Please apply this series to net-next. ==================== Signed-off-by: -

We cannot take rtnl lock while enabling/disabling SR-IOV as VF probe will take an rtnl lock. o Disable spoofchk by default. Signed-off-by:

Ying Xue says: ==================== tipc: overhaul node action flags We currently have two problems with the node flags field: - The naming of the individual action flags is unclear and confusing - The flags are often not cleared individually, making it hard to follow where this happens. So the series aims to solve above two problems. ==================== Signed-off-by: -
Ying Xue authored
Each node action flag should be set or cleared separately, instead we now set the whole flags variable in one shot, and it's turned out to be hard to see which other flags are affected. Therefore, for instance, we explicitly clear TIPC_WAIT_OWN_LINKS_DOWN bit in node_lost_contact(). Signed-off-by:

Tom Herbert says: ==================== net: Checksum offload changes - Part II I am working on overhauling RX checksum offload. Goals of this effort are: - Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY - Preserve CHECKSUM_COMPLETE through encapsulation layers - Don't do skb_checksum more than once per packet - Unify GRO and non-GRO csum verification as much as possible - Unify the checksum functions (checksum_init) - Simply code What is in this second patch set: - Call common inet checksum validation functions in ICMP{4,6}, GRE{4,6}, and IGMP. - In UDP, verify checksum before handing off to encap_rcv. - Remove custom UDP checksum validation code in L2TP. Please review carefully and test if possible, mucking with basic checksum functions is always a little precarious :-) ==================== Signed-off-by: -

Validating the UDP checksum is now done in UDP before handing packets to the encapsulation layer. Note that this also eliminates the "feature" where L2TP can ignore a non-zero UDP checksum (doing this was contrary to RFC 1122). Signed-off-by:
