2018-06-04RISC-V: Preliminary Perf SupportPalmer Dabbelt
The RISC-V ISA defines a core set of performance counters that must exist on all processors along with a standard way to add more performance counters. This patch set adds preliminary perf support for RISC-V systems. Long term we'll move to model where all PMUs can be built into the kernel at the same time, detected at runtime (possibly via device tree), and provided to userspace. Since we currently only support the ISA-mandated performance counters there's no need to detect anything right now. Signed-off-by: Palmer Dabbelt <palmer@sifive.com>

This patch provide a basic PMU, riscv_base_pmu, which supports two general hardware event, instructions and cycles. Furthermore, this PMU serves as a reference implementation to ease the portings in the future. riscv_base_pmu should be able to run on any RISC-V machine that conforms to the Priv-Spec. Note that the latest qemu model hasn't fully support a proper behavior of Priv-Spec 1.10 yet, but work around should be easy with very small fixes.

2018-06-04MAINTAINERS: Add myself as a maintainer for SiFive's driversPalmer Dabbelt
There aren't actually any files in the tree that match these patterns right now, but we've just started submitting our drivers so I thought it would be good to make sure there's at least someone at SiFive who's listed as maintaining them. I'm leaving the RISC-V lists on here because: * As of today, all the RISC-V ASICs that people can actually buy are from SiFive -- though hopefully there'll be more soon! * The RTL for many of our devices is open source, so I anticipate these devices might make they way chips from other vendors. * We may standardize some of these devices as part of a RISC-V specification at some point in the future. I'm a bit swamped right now so I might not be the most active maintainer of these drivers, but I think it'd be good to make sure someone who has hardware access gets CC'd on updates to our drivers just as a sanity check. Hopefully that's an OK way to handle this. Signed-off-by: Palmer Dabbelt <palmer@sifive.com>

2018-06-04riscv: Fix the bug in memory access fixup codeAlan Kao
A piece of fixup code is currently shared by __copy_user and __clear_user. It first disables the access to user-space memory and then returns the "n" argument, which represents #(bytes not processed). However,__copy_user's "n" is in register a2, while __clear_user's in a1, and thus it causes errors for programs like setdomainname02 testcase in LTP. This patch fixes this issue by separating their fixup code and returning the right value for the kernel to handle a relative fault properly.

2018-06-04rxrpc: Fix handling of call quietly cancelled out on serverDavid Howells
Sometimes an in-progress call will stop responding on the fileserver when the fileserver quietly cancels the call with an internally marked abort (RX_CALL_DEAD), without sending an ABORT to the client. This causes the client's call to eventually expire from lack of incoming packets directed its way, which currently leads to it being cancelled locally with ETIME. Note that it's not currently clear as to why this happens as it's really hard to reproduce. The rotation policy implement by kAFS, however, doesn't differentiate between ETIME meaning we didn't get any response from the server and ETIME meaning the call got cancelled mid-flow. The latter leads to an oops when fetching data as the rotation partially resets the afs_read descriptor, which can result in a cleared page pointer being dereferenced because that page has already been filled. Handle this by the following means: (1) Set a flag on a call when we receive a packet for it. (2) Store the highest packet serial number so far received for a call (bearing in mind this may wrap). (3) If, when the "not received anything recently" timeout expires on a call, we've received at least one packet for a call and the connection as a whole has received packets more recently than that call, then cancel the call locally with ECONNRESET rather than ETIME. This indicates that the call was definitely in progress on the server. (4) In kAFS, if the rotation algorithm sees ECONNRESET rather than ETIME, don't try the next server, but rather abort the call. This avoids the oops as we don't try to reuse the afs_read struct. Rather, as-yet ungotten pages will be reread at a later data. Also: (5) Add an rxrpc tracepoint to log detection of the call being reset. Without this, I occasionally see an oops like the following: general protection fault: 0000 [#1] SMP PTI ...

Commit bf6fa2c893c5 ("bpf: implement bpf_get_current_cgroup_id() helper") introduced a new helper bpf_get_current_cgroup_id(). The helper has a dependency on CONFIG_CGROUPS. When CONFIG_CGROUPS is not defined, using the helper will result the following verifier error: kernel subsystem misconfigured func bpf_get_current_cgroup_id#80 which is hard for users to interpret. Guarding the reference to bpf_get_current_cgroup_id_proto with CONFIG_CGROUPS will result in below better message: unknown func bpf_get_current_cgroup_id#80 Fixes: bf6fa2c893c5 ("bpf: implement bpf_get_current_cgroup_id() helper") Suggested-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

Björn Töpel says: ==================== An issue with the current AF_XDP uapi raised by Mykyta Iziumtsev (see https://www.spinics.net/lists/netdev/msg503664.html) is that it does not support NICs that have a "type-writer" model in an efficient way. In this model, a memory window is passed to the hardware and multiple frames might be filled into that window, instead of just one that we have in the current fixed frame-size model. This patch set fixes two bugs in the current implementation and then changes the uapi so that the type-writer model can be supported efficiently by a possible future extension of AF_XDP. These are the uapi changes in this patch: * Change the "u32 idx" in the descriptors to "u64 addr". The current idx based format does NOT work for the type-writer model (as packets can start anywhere within a frame) but that a relative address pointer (the u64 addr) works well for both models in the prototype code we have that supports both models. We increased it from u32 to u64 to support umems larger than 4G. We have also removed the u16 offset when having a "u64 addr" since that information is already carried in the least significant bits of the address. * We want to use "u8 padding[5]" for something useful in the future (since we are not allowed to change its name), so we now call it just options so it can be extended for various purposes in the future. It is an u32 as that it what is left of the 16 byte descriptor. * We changed the name of frame_size in the UMEM_REG setsockopt to chunk_size since this naming also makes sense to the type-writer model. With these changes to the uapi, we believe the type-writer model can be supported without having to resort to a new descriptor format. The type-writer model could then be supported, from the uapi point of view, by setting a flag at bind time and providing a new flag bit in the options field of the descriptor that signals to user space that all packets have been written in a chunk. Or with a new chunk completion queue as suggested by Mykyta in his latest feedback mail on the list. We based this patch set on bpf-next commit bd3a08aaa9a3 ("bpf: flowlabel in bpf_fib_lookup should be flowinfo") The structure of the patch set is as follows: Patches 1-2: Fixes two bugs in the current implementation. Patches 3-4: Prepares the uapi for a "type-writer" model and modifies the sample application so that it works with the new uapi. Patch 5: Small performance improvement patch for the sample application.

2018-06-04IB/hfi1: Fix user context tail allocation for DMA_RTAILMike Marciniszyn
The following code fails to allocate a buffer for the tail address that the hardware DMAs into when the user context DMA_RTAIL is set. if (HFI1_CAP_KGET_MASK(rcd->flags, DMA_RTAIL)) { rcd->rcvhdrtail_kvaddr = dma_zalloc_coherent( &dd->pcidev->dev, PAGE_SIZE, &dma_hdrqtail, gfp_flags); if (!rcd->rcvhdrtail_kvaddr) goto bail_free; rcd->rcvhdrqtailaddr_dma = dma_hdrqtail; } So the rcvhdrtail_kvaddr would then be NULL. The mmap logic fails to check for a NULL rcvhdrtail_kvaddr. The fix is to test for both user and kernel DMA_TAIL options during the allocation as well as testing for a NULL rcvhdrtail_kvaddr during the mmap processing. Additionally, all downstream testing of the capmask for DMA_RTAIL have been eliminated in favor of testing rcvhdrtail_kvaddr. Cc: <stable@vger.kernel.org> # 4.9.x Reviewed-by: Michael J.

2018-06-04sh_eth: make sh_eth_soft_swap() work on ARMSergei Shtylyov
Browsing thru the driver disassembly, I noticed that ARM gcc generated no code whatsoever for sh_eth_soft_swap() while building a little-endian kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however it got implicitly #define'd when building with the SH gcc (I could only find the explicit #define __LITTLE_ENDIAN that was #include'd when building a little-endian kernel). Luckily, the Ether controller only doing big- endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we need to fix the #ifdef inside sh_eth_soft_swap() to something that would work on all architectures...

2018-06-04NFS: Filter cache invalidation when holding a delegationTrond Myklebust
If the client holds a delegation, then ensure we filter out attempts to invalidate the size, owner, group owner, or mode unless we made the change, in which case, check that NFS_INO_REVAL_FORCED is set by the caller. Always filter out attempts to invalidate the change attribute and size, since we are authoritative for those. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2018-06-04NFS: Ignore NFS_INO_REVAL_FORCED in nfs_check_inode_attributes()Trond Myklebust
If we hold a delegation, we should not need to call nfs_check_inode_attributes() since we already know which attributes are valid, and which ones may still need revalidation. The state of the NFS_INO_REVAL_FORCED flag is therefore irrelevant. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
