2017-02-12bnxt_en: Do not setup PHY unless driving a single PF.Michael Chan1-0/+3

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree, most relevantly they are: 1) Extend nft_exthdr to allow to match TCP options bitfields, from Manuel Messner. 2) Allow to check if IPv6 extension header is present in nf_tables, from Phil Sutter. 3) Allow to set and match conntrack zone in nf_tables, patches from Florian Westphal. 4) Several patches for the nf_tables set infrastructure, this includes cleanup and preparatory patches to add the new bitmap set type. 5) Add optional ruleset generation ID check to nf_tables and allow to delete rules that got no public handle yet via NFTA_RULE_ID. These patches add the missing kernel infrastructure to support rule deletion by description from userspace. 6) Missing NFT_SET_OBJECT flag to select the right backend when sets stores an object map. 7) A couple of cleanups for the expectation and SIP helper, from Gao feng. ==================== Signed-off-by: David S.

2017-02-12netfilter: nf_tables: add NFTA_RULE_ID attributePablo Neira Ayuso3-0/+31
This new attribute allows us to uniquely identify a rule in transaction. Robots may trigger an insertion followed by deletion in a batch, in that scenario we still don't have a public rule handle that we can use to delete the rule. This is similar to the NFTA_SET_ID attribute that allows us to refer to an anonymous set from a batch. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-12netfilter: nf_tables: add check_genid to the nfnetlink subsystemPablo Neira Ayuso1-0/+6
This patch implements the check generation id as provided by nfnetlink. This allows us to reject ruleset updates against stale baseline, so userspace can retry update with a fresh ruleset cache. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-02-12netfilter: nfnetlink: allow to check for generation IDPablo Neira Ayuso3-4/+40
This patch allows userspace to specify the generation ID that has been used to build an incremental batch update. If userspace specifies the generation ID in the batch message as attribute, then nfnetlink compares it to the current generation ID so you make sure that you work against the right baseline. Otherwise, bail out with ERESTART so userspace knows that its changeset is stale and needs to respin. Userspace can do this transparently at the cost of taking slightly more time to refresh caches and rework the changeset. This check is optional, if there is no NFNL_BATCH_GENID attribute in the batch begin message, then no check is performed. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2017-02-11net_sched: fix error recovery at qdisc creationEric Dumazet5-23/+19
Dmitry reported uses after free in qdisc code [1] The problem here is that ops->init() can return an error. qdisc_create_dflt() then call ops->destroy(), while qdisc_create() does _not_ call it. Four qdisc chose to call their own ops->destroy(), assuming their caller would not. This patch makes sure qdisc_create() calls ops->destroy() and fixes the four qdisc to avoid double free.

2017-02-10l2tp: do not use udp_ioctl()Eric Dumazet3-2/+28
udp_ioctl(), as its name suggests, is used by UDP protocols, but is also used by L2TP :( L2TP should use its own handler, because it really does not look the same. SIOCINQ for instance should not assume UDP checksum or headers. Thanks to Andrey and syzkaller team for providing the report and a nice reproducer. While crashes only happen on recent kernels (after commit 7c13f97ffde6 ("udp: do fwd memory scheduling on dequeue")), this probably needs to be backported to older kernels.

2017-02-10Merge branch 'bpf-selftests-improve-and-use-library'David S. Miller11-300/+301
Mickaël Salaün says: ==================== Improve BPF selftests and use the library (net-next tree) This series brings some fixes to selftests, add the ability to test unprivileged BPF programs as root and replace bpf_sys.h with calls to the BPF library. This is intended for the net-next tree and apply on c0e4dadb3494 ("net: dsa: mv88e6xxx: Move forward declaration to where it is needed"). Changes since v4: * align text for function calls as requested by Daniel Borkmann (bpf_load_program and bpf_map_update_elem) * rebase Changes since v3: * keep the bzero() calls Changes since v2: * use the patches from two previous series (unprivileged tests and bpf_sys.h replacement) * include one more stdint.h * rebase on net-next * add this cover letter Changes since v1: * exclude patches not intended for the net-next tree ==================== Signed-off-by: David S.
