All map types and prog types are registered to the BPF core through bpf_register_map_type() and bpf_register_prog_type() during init and remain unchanged thereafter. As by design we don't (and never will) have any pluggable code that can register to that at any later point in time, lets mark all the existing bpf_{map,prog}_type_list objects in the tree as __ro_after_init, so they can be moved to read-only section from then onwards.

After commit 34a5102c ("net: bgmac: allocate struct bgmac just once & don't copy it") the mac_addr member of struct bgmac is no longer necessary to pass the MAC address to bgmac_enet_probe(). Instead it can directly be stored in netdev->dev_addr. Also use eth_hw_addr_random() instead of eth_random_addr() in case a random MAC is nedded. This will make sure netdev->addr_assign_type will be properly set. Signed-off-by: NTobias Klauser <tklauser@distanz.ch> Acked-by: NJon Mason <jon.mason@broadcom.com> Signed-off-by: NDavid S.

Herbert Xu says: ==================== rhashtable: Handle table allocation failure during insertion v2 - Added Ack to patch 2. Fixed RCU annotation in code path executed by rehasher by using rht_dereference_bucket. v1 - This series tackles the problem of table allocation failures during insertion. The issue is that we cannot vmalloc during insertion. This series deals with this by introducing nested tables. The first two patches removes manual hash table walks which cannot work on a nested table. The final patch introduces nested tables. I've tested this with test_rhashtable and it appears to work. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds code that handles GFP_ATOMIC kmalloc failure on insertion. As we cannot use vmalloc, we solve it by making our hash table nested. That is, we allocate single pages at each level and reach our desired table size by nesting them. When a nested table is created, only a single page is allocated at the top-level. Lower levels are allocated on demand during insertion. Therefore for each insertion to succeed, only two (non-consecutive) pages are needed. After a nested table is created, a rehash will be scheduled in order to switch to a vmalloced table as soon as possible. Also, the rehash code will never rehash into a nested table. If we detect a nested table during a rehash, the rehash will be aborted and a new rehash will be scheduled. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

There are two problems with the function tipc_sk_reinit. Firstly it's doing a manual walk over an rhashtable. This is broken as an rhashtable can be resized and if you manually walk over it during a resize then you may miss entries. Secondly it's missing memory barriers as previously the code used spinlocks which provide the barriers implicitly. This patch fixes both problems.

The function glock_hash_walk walks the rhashtable by hand. This is broken because if it catches the hash table in the middle of a rehash, then it will miss entries.

Or Gerlitz says: ==================== net/sched: Reflect HW offload status in classifiers Currently there is no way of querying whether a filter is offloaded to HW or not when using "both" policy (where none of skip_sw or skip_hw flags are set by user-space). Added two new flags, "in hw" and "not in hw" such that user space can determine if a filter is actually offloaded to hw. The "in hw" UAPI semantics was chosen so it's similar to the "skip hw" flag logic. If none of these two flags are set, this signals running over older kernel. As an example, add one vlan push + fwd rule, one matchall rule and one u32 rule without any flags, and another vlan + fwd skip_sw rule, such that the different TC classifier attempt to offload all of them -- all over mlx5 SRIOV VF rep: flower skip_sw indev eth2_0 src_mac e4:11:22:33:44:50 dst_mac e4:1d:2d:a5:f3:9d action vlan push id 52 action mirred egress redirect dev eth2 flower indev eth2_0 src_mac e4:11:22:33:44:50 dst_mac e4:11:22:33:44:51 action vlan push id 53 action mirred egress redirect dev eth2 u32 ht 800: flowid 800:1 match ip src 192.168.1.0/24 action drop Since that VF rep doesn't offload matchall/u32 and can currently offload only one vlan push rule we expect three of the rules not to be offloaded: filter protocol ip pref 99 u32 filter protocol ip pref 99 u32 fh 800: ht divisor 1 filter protocol ip pref 99 u32 fh 800::1 order 1 key ht 800 bkt 0 flowid 800:1 not in_hw match c0a80100/ffffff00 at 12 action order 1: gact action drop random type none pass val 0 index 8 ref 1 bind 1 filter protocol all pref 49150 matchall filter protocol all pref 49150 matchall handle 0x1 not in_hw action order 1: mirred (Egress Mirror to device veth1) pipe index 27 ref 1 bind 1 filter protocol ip pref 49151 flower filter protocol ip pref 49151 flower handle 0x1 indev eth2_0 dst_mac e4:11:22:33:44:51 src_mac e4:11:22:33:44:50 eth_type ipv4 not in_hw action order 1: vlan push id 53 protocol 802.1Q priority 0 pipe index 20 ref 1 bind 1 action order 2: mirred (Egress Redirect to device eth2) stolen index 26 ref 1 bind 1 filter protocol ip pref 49152 flower filter protocol ip pref 49152 flower handle 0x1 indev eth2_0 dst_mac e4:1d:2d:a5:f3:9d src_mac e4:11:22:33:44:50 eth_type ipv4 skip_sw in_hw action order 1: vlan push id 52 protocol 802.1Q priority 0 pipe index 19 ref 1 bind 1 action order 2: mirred (Egress Redirect to device eth2) stolen index 25 ref 1 bind 1 v3 --> v4 changes: - removed extra parenthesis (Dave) v2 --> v3 changes: - fixed the matchall dump flags patch to do proper checks (Jakub) - added the same proper checks to flower where they were missing - that flower patch was added as #1 and hence all the other patches are offed-by-one v1 --> v2 changes: - applied feedback from Jakub and Dave -- where none of the skip flags were set, the suggested approach didn't allow user space to distringuish between old kernel to a case when offloading to HW worked fine. ==================== Signed-off-by: NDavid S.

All rx and rx netdev interrupts are handled by respectively by mlx4_en_rx_irq() and mlx4_en_tx_irq() which simply schedule a NAPI. But mlx4_eq_int() also fires a tasklet to service all items that were queued via mlx4_add_cq_to_tasklet(), but this handler was not called unless user cqe was handled. This is very confusing, as "mpstat -I SCPU ..." show huge number of tasklet invocations. This patch saves this overhead, by carefully firing the tasklet directly from mlx4_add_cq_to_tasklet(), removing four atomic operations per IRQ.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-02-16 This series contains updates to ixgbe only. Tony updates the driver to advertise 2.5Gb and 5.0Gb if the adapter supports it. Stephen Hemminger renames our dcbnl_ops since it is global to ixgbe_dcbnl_ops to avoid namespace issues. Mark updates the driver version based on the recent changes. Alex has the remainder of the changes, starting with consolidating functions that represent logical steps in the receive process so we can later update them more easily (and align with igb). Modify the receive path to only synchronize the length of the frame versus the entire buffer. Provided performance improvements by adding support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. Also made additional performance gains by batching the page count updates instead of doing them one at a time. Adjusted the receive path to use 3k buffers with 8k backing them in order to support build_skb with jumbo frames. Made additional driver improvements by using the length of the packet instead of the DD status to determine if a new descriptor is ready to be processed, which cuts down on reads. To reduce code duplication, pulled apart the receive path into separate functions. Added support for providing a buffer with headroom and tailroom to allow for shared info for NET_SKB_PAD and NET_IP_ALIGN. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
