2017-03-14qed: Fix interrupt flags on Rx LL2Ram Amrani
Before iterating over the the LL2 Rx ring, the ring's spinlock is taken via spin_lock_irqsave(). The actual processing of the packet [including handling by the protocol driver] is done without said lock, so qed releases the spinlock and re-claims it afterwards. Problem is that the final spin_lock_irqrestore() at the end of the iteration uses the original flags saved from the initial irqsave() instead of the flags from the most recent irqsave(). So it's possible that the interrupt status would be incorrect at the end of the processing.

Commit 653d2ffd6405 ("qed*: Fix link indication race") introduced another race - one of the inner functions called from the link-change flow is explicitly using the slowpath context dedicated PTT instead of gaining that PTT from the caller. Since this flow can now be called from a different context as well, we're in risk of the PTT breaking.

2017-02-27qed: Fix race with multiple VFsMintz, Yuval
A PF syncronizes all IOV activity relating to its VFs by using a single workqueue handling the work. The workqueue would reach a bitmask of pending VF events and act upon each in turn. Problem is that the indication of a VF message [which sets the 'vf event' bit for that VF] arrives and is set in the slowpath attention context, which isn't syncronized with the processing of the events. When multiple VFs are present, it's possible that PF would lose the indication of one of the VF's pending evens, leading that VF to later timeout. Instead of adding locks/barriers, simply move from a bitmask into a per-VF indication inside that VF entry in the PF database.

2017-02-20qed*: Fix link indication raceMintz, Yuval
Driver changes the link properties via communication with the management firmware, and re-reads the resulting link status when it receives an indication that the link has changed. However, there are certain scenarios where such indications might be missing, and so driver also re-reads the current link results without attention in several places. Specifically, it does so during load and when resetting the link. This creates a race where driver might reflect incorrect link status - e.g., when explicit reading of the link status is switched by attention with the changed configuration. Correct this flow by a lock syncronizing the handling of the link indications [both explicit requests and attention]. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-20qed: Don't allocate SBs using main PTTMintz, Yuval
Flows accessing registers require the flow to hold a PTT entry. To protect 'major' load/unload flows a main_ptt is pre-allocated to guarantee such flows wouldn't be blocked by PTT being unavailable. Status block initialization currently uses the main_ptt which is incorrect, as this flow might run concurrently to others [E.g., loading qedr while toggling qede]. That would have dire effects as it means registers' access to device breaks and further read/writes might access incorrect addresses. Instead, when initializing status blocks acquire/release a PTT as part of the flow. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2017-02-20qed: Reflect PF link when initializing VFMintz, Yuval
VF learns of the current link state via its bulletin board, which might reflect either the physical link state or some user-configured logical state. Whenever the physical link changes or whnever such a configuration is explicitly made by user the PF driver would update the bulletin that the VF reads. But if neither has happened - i.e., PF still hasn't got a physical link up and no additional configuration was done the VF wouldn't have a valid link information available. Simply reflect the physical link state whenever the VF is initialized. The user could then affect it however he wants. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.

2017-01-25bpf: add initial bpf tracepointsDaniel Borkmann
This work adds a number of tracepoints to paths that are either considered slow-path or exception-like states, where monitoring or inspecting them would be desirable. For bpf(2) syscall, tracepoints have been placed for main commands when they succeed. In XDP case, tracepoint is for exceptions, that is, f.e. on abnormal BPF program exit such as unknown or XDP_ABORTED return code, or when error occurs during XDP_TX action and the packet could not be forwarded. Both have been split into separate event headers, and can be further extended. Worst case, if they unexpectedly should get into our way in future, they can also removed [1]. Of course, these tracepoints (like any other) can be analyzed by eBPF itself, etc. Example output: # ./perf record -a -e bpf:* sleep 10 # ./perf script sock_example 6197 [005] 283.980322: bpf:bpf_map_create: map type=ARRAY ufd=4 key=4 val=8 max=256 flags=0 sock_example 6197 [005] 283.980721: bpf:bpf_prog_load: prog=a5ea8fa30ea6849c type=SOCKET_FILTER ufd=5 sock_example 6197 [005] 283.988423: bpf:bpf_prog_get_type: prog=a5ea8fa30ea6849c type=SOCKET_FILTER sock_example 6197 [005] 283.988443: bpf:bpf_map_lookup_elem: map type=ARRAY ufd=4 key=[06 00 00 00] val=[00 00 00 00 00 00 00 00] [...] sock_example 6197 [005] 288.990868: bpf:bpf_map_lookup_elem: map type=ARRAY ufd=4 key=[01 00 00 00] val=[14 00 00 00 00 00 00 00] swapper 0 [005] 289.338243: bpf:bpf_prog_put_rcu: prog=a5ea8fa30ea6849c type=SOCKET_FILTER [1] https://lwn.net/Articles/705270/ Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.

2017-01-08net: make ndo_get_stats64 a void functionstephen hemminger
The network device operation for reading statistics is only called in one place, and it ignores the return value. Having a structure return value is potentially confusing because some future driver could incorrectly assume that the return value was used. Fix all drivers with ndo_get_stats64 to have a void function. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
