2016-12-05scsi: hpsa: use %phN for short hex dumpsRasmus Villemoes
Passing one instead of 8 or 16 arguments reduces the size of the generated code somewhat: add/remove: 2/3 grow/shrink: 1/4 up/down: 1772/-2137 (-365) There's one more candidate, unique_id_show, but that uses %02X, and I'm not sure it would be ok to start using lowercase there, so I've left it alone for now.

This patch addresses 4 problems in the module probe/remove: - When hisi_sas_shost_alloc() fails after we alloc shost memory, we should free shost memory before the function returns. - When hisi_sas_probe() fails after we alloc the HBA memories, we should also free the HBA memories. - We should free shost memory at the end of hisi_sas_remove(). - sha->core.shost is set twice, so remove extra set.

2016-12-05net: ep93xx_eth: Do not crash unloading moduleFlorian Fainelli
When we unload the ep93xx_eth, whether we have opened the network interface or not, we will either hit a kernel paging request error, or a simple NULL pointer de-reference because: - if ep93xx_open has been called, we have created a valid DMA mapping for ep->descs, when we call ep93xx_stop, we also call ep93xx_free_buffers, ep->descs now has a stale value - if ep93xx_open has not been called, we have a NULL pointer for ep->descs, so performing any operation against that address just won't work Fix this by adding a NULL pointer check for ep->descs which means that ep93xx_free_buffers() was able to successfully tear down the descriptors and free the DMA cookie as well.

2016-12-05bpf: add prog_digest and expose it via fdinfo/netlinkDaniel Borkmann
When loading a BPF program via bpf(2), calculate the digest over the program's instruction stream and store it in struct bpf_prog's digest member. This is done at a point in time before any instructions are rewritten by the verifier. Any unstable map file descriptor number part of the imm field will be zeroed for the hash. fdinfo example output for progs: # cat /proc/1590/fdinfo/5 pos: 0 flags: 02000002 mnt_id: 11 prog_type: 1 prog_jited: 1 prog_digest: b27e8b06da22707513aa97363dfb11c7c3675d28 memlock: 4096 When programs are pinned and retrieved by an ELF loader, the loader can check the program's digest through fdinfo and compare it against one that was generated over the ELF file's program section to see if the program needs to be reloaded. Furthermore, this can also be exposed through other means such as netlink in case of a tc cls/act dump (or xdp in future), but also through tracepoints or other facilities to identify the program. Other than that, the digest can also serve as a base name for the work in progress kallsyms support of programs. The digest doesn't depend/select the crypto layer, since we need to keep dependencies to a minimum. iproute2 will get support for this facility.

Commit 18cdb37ebf4c ("net: sched: do not use tcf_proto 'tp' argument from call_rcu") removed the last usage of tp from cls_bpf_delete_prog(), so also remove it from the function as argument to not give a wrong impression. tp is illegal to access from this callback, since it could already have been freed. Refactor the deletion code a bit, so that cls_bpf_destroy() can call into the same code for prog deletion as cls_bpf_delete() op, instead of having it unnecessarily duplicated.

2016-12-05net_sched: gen_estimator: complete rewrite of rate estimatorsEric Dumazet
1) Old code was hard to maintain, due to complex lock chains. (We probably will be able to remove some kfree_rcu() in callers) 2) Using a single timer to update all estimators does not scale. 3) Code was buggy on 32bit kernel (WRITE_ONCE() on 64bit quantity is not supposed to work well) In this rewrite : - I removed the RB tree that had to be scanned in gen_estimator_active(). qdisc dumps should be much faster. - Each estimator has its own timer. - Estimations are maintained in net_rate_estimator structure, instead of dirtying the qdisc. Minor, but part of the simplification. - Reading the estimator uses RCU and a seqcount to provide proper support for 32bit kernels. - We reduce memory need when estimators are not used, since we store a pointer, instead of the bytes/packets counters. - xt_rateest_mt() no longer has to grab a spinlock.

2016-12-05bnx2x: Prevent tunnel config for 577xxMintz, Yuval
Only the 578xx adapters are capable of configuring UDP ports for the purpose of tunnelling - doing the same on 577xx might lead to a firmware assertion. We're already not claiming support for any related feature for such devices, but we also need to prevent the configuration of the UDP ports to the device in this case.

2016-12-05bnx2x: Correct ringparam estimate when DOWNMintz, Yuval
Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface.

2016-12-05net/sched: cls_flower: Set the filter Hardware device for all use-casesHadar Hen Zion
Check if the returned device from tcf_exts_get_dev function supports tc offload and in case the rule can't be offloaded, set the filter hw_dev parameter to the original device given by the user. The filter hw_device parameter should always be set by fl_hw_replace_filter function, since this pointer is used by dump stats and destroy filter for each flower rule (offloaded or not).
