2020-03-24net/mlx5e: Fix ICOSQ recovery flow with Striding RQAya Levin3-8/+26
In striding RQ mode, the buffers of an RX WQE are first prepared and posted to the HW using a UMR WQEs via the ICOSQ. We maintain the state of these in-progress WQEs in the RQ SW struct. In the flow of ICOSQ recovery, the corresponding RQ is not in error state, hence: - The buffers of the in-progress WQEs must be released and the RQ metadata should reflect it. - Existing RX WQEs in the RQ should not be affected. For this, wrap the dealloc of the in-progress WQEs in a function, and use it in the ICOSQ recovery flow instead of mlx5e_free_rx_descs().

2020-03-24net/mlx5e: Fix missing reset of SW metadata in Striding RQ resetAya Levin1-2/+4
When resetting the RQ (moving RQ state from RST to RDY), the driver resets the WQ's SW metadata. In striding RQ mode, we maintain a field that reflects the actual expected WQ head (including in progress WQEs posted to the ICOSQ). It was mistakenly not reset together with the WQ. Fix this here.

2020-03-24net/mlx5e: Enhance ICOSQ WQE info fieldsAya Levin3-6/+7
Add number of WQEBBs (WQE's Basic Block) to WQE info struct. Set the number of WQEBBs on WQE post, and increment the consumer counter (cc) on completion. In case of error completions, the cc was mistakenly not incremented, keeping a gap between cc and pc (producer counter). This failed the recovery flow on the ICOSQ from a CQE error which timed-out waiting for the cc and pc to meet.

Nvidia card may come with a "phantom" UCSI device, and its driver gets stuck in probe routine, prevents any system PM operations like suspend. There's an unaccounted case that the target time can equal to jiffies in gpu_i2c_check_status(), let's solve that by using readl_poll_timeout() instead of jiffies comparison functions.

2020-03-24selftests: netfilter: add nfqueue test caseFlorian Westphal4-1/+695
Add a test case to check nf queue infrastructure. Could be extended in the future to also cover serialization of conntrack, uid and secctx attributes in nfqueue. For now, this checks that 'queue bypass' works, that a queue rule with no bypass option blocks traffic and that userspace receives the expected number of packets. For this we add two queues and hook all of prerouting/input/forward/output/postrouting. Packets get queued twice with a dummy base chain in between: This passes with current nf tree, but reverting commit 946c0d8e6ed4 ("netfilter: nf_queue: fix reinject verdict handling") makes this trip (it processes 30 instead of expected 20 packets). v2: update config file with queue and other options missing/needed for other tests. v3: also test with tcp, this reveals problem with commit 28f8bfd1ac94 ("netfilter: Support iif matches in POSTROUTING"), due to skb->dev pointing at another skb in the retransmit rbtree (skb->dev aliases to rbnode child).

2020-03-24netfilter: nft_set_rbtree: Detect partial overlaps on insertionStefano Brivio1-3/+67
...and return -ENOTEMPTY to the front-end in this case, instead of proceeding. Currently, nft takes care of checking for these cases and not sending them to the kernel, but if we drop the set_overlap() call in nft we can end up in situations like: # nft add table t # nft add set t s '{ type inet_service ; flags interval ; }' # nft add element t s '{ 1 - 5 }' # nft add element t s '{ 6 - 10 }' # nft add element t s '{ 4 - 7 }' # nft list set t s table ip t { set s { type inet_service flags interval elements = { 1-3, 4-5, 6-7 } } } This change has the primary purpose of making the behaviour consistent with nft_set_pipapo, but is also functional to avoid inconsistent behaviour if userspace sends overlapping elements for any reason. v2: When we meet the same key data in the tree, as start element while inserting an end element, or as end element while inserting a start element, actually check that the existing element is active, before resetting the overlap flag (Pablo Neira Ayuso) Signed-off-by: Stefano Brivio <[email protected]> Signed-off-by: Pablo Neira Ayuso <[email protected]>

2020-03-24netfilter: nf_tables: Allow set back-ends to report partial overlaps on ↵Pablo Neira Ayuso1-0/+5
insertion Currently, the -EEXIST return code of ->insert() callbacks is ambiguous: it might indicate that a given element (including intervals) already exists as such, or that the new element would clash with existing ones. If identical elements already exist, the front-end is ignoring this without returning error, in case NLM_F_EXCL is not set. However, if the new element can't be inserted due an overlap, we should report this to the user. To this purpose, allow set back-ends to return -ENOTEMPTY on collision with existing elements, translate that to -EEXIST, and return that to userspace, no matter if NLM_F_EXCL was set.

Unlike NL_SET_ERR_* macros, nl_set_extack_cookie_u64() and nl_set_extack_cookie_u32() helpers do not check extack argument for null and neither do their callers, as syzbot recently discovered for ethnl_parse_header(). Instead of fixing the callers and leaving the trap in place, add check of null extack to both helpers to make them consistent with NL_SET_ERR_* macros. v2: drop incorrect second Fixes tag Fixes: 2363d73a2f3e ("ethtool: reject unrecognized request flags") Reported-by: [email protected] Signed-off-by: Michal Kubecek <[email protected]> Signed-off-by: David S.
