5cd5548 KVM: x86: fix TRACE_INCLUDE_PATH and remove -I. header search paths The header search path -I. in kernel Makefiles is very suspicious; it allows the compiler to search for headers in the top of $(srctree), where obviously no header file exists. The reason of having -I. here is to make the incorrectly set TRACE_INCLUDE_PATH working. As the comment block in include/trace/define_trace.h says, TRACE_INCLUDE_PATH should be a relative path to the define_trace.h Fix the TRACE_INCLUDE_PATH, and remove the iffy include paths.

5ad6ece KVM: VMX: Move vmx_vcpu_run()'s VM-Enter asm blob to a helper function ...along with the function's STACK_FRAME_NON_STANDARD tag. Moving the asm blob results in a significantly smaller amount of code that is marked with STACK_FRAME_NON_STANDARD, which makes it far less likely that gcc will split the function and trigger a spurious objtool warning. As a bonus, removing STACK_FRAME_NON_STANDARD from vmx_vcpu_run() allows the bulk of code to be properly checked by objtool. Because %rbp is not loaded via VMCS fields, vmx_vcpu_run() must manually save/restore the host's RBP and load the guest's RBP prior to calling vmx_vmenter(). Modifying %rbp triggers objtool's stack validation code, and so vmx_vcpu_run() is tagged with STACK_FRAME_NON_STANDARD since it's impossible to avoid modifying %rbp. Unfortunately, vmx_vcpu_run() is also a gigantic function that gcc will split into separate functions, e.g. so that pieces of the function can be inlined. Splitting the function means that the compiled Elf file will contain one or more vmx_vcpu_run.part.* functions in addition to a vmx_vcpu_run function. Depending on where the function is split, objtool may warn about a "call without frame pointer save/setup" in vmx_vcpu_run.part.* since objtool's stack validation looks for exact names when whitelisting functions tagged with STACK_FRAME_NON_STANDARD. Up until recently, the undesirable function splitting was effectively blocked because vmx_vcpu_run() was tagged with __noclone. At the time, __noclone had an unintended side effect that put vmx_vcpu_run() into a separate optimization unit, which in turn prevented gcc from inlining the function (or any of its own function calls) and thus eliminated gcc's motivation to split the function. Removing the __noclone attribute allowed gcc to optimize vmx_vcpu_run(), exposing the objtool warning. Kudos to Qian Cai for root causing that the fnsplit optimization is what caused objtool to complain.

619ad84 KVM: nSVM: clear events pending from svm_complete_interrupts() when exiting to L1 kvm-unit-tests' eventinj "NMI failing on IDT" test results in NMI being delivered to the host (L1) when it's running nested. The problem seems to be: svm_complete_interrupts() raises 'nmi_injected' flag but later we decide to reflect EXIT_NPF to L1. The flag remains pending and we do NMI injection upon entry so it got delivered to L1 instead of L2. It seems that VMX code solves the same issue in prepare_vmcs12(), this was introduced with code refactoring in commit 5f3d5799974b ("KVM: nVMX: Rework event injection and recovery").

ffe4cfc net/mlx4_core: Fix error handling when initializing CQ bufs in the driver Procedure mlx4_init_user_cqes() handles returns by copy_to_user incorrectly. copy_to_user() returns the number of bytes not copied. Thus, a non-zero return should be treated as a -EFAULT error (as is done elsewhere in the kernel). However, mlx4_init_user_cqes() error handling simply returns the number of bytes not copied (instead of -EFAULT). Note, though, that this is a harmless bug: procedure mlx4_alloc_cq() (which is the only caller of mlx4_init_user_cqes()) treats any non-zero return as an error, but that returned error value is processed internally, and not passed further up the call stack. In addition, fixes the following sparse warning: warning: incorrect type in argument 1 (different address spaces) expected void [noderef] <asn:1>*to got void *buf Fixes: e45678973dcb ("{net, IB}/mlx4: Initialize CQ buffers in the driver when possible") Reported by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

ecf938f sctp: set flow sport from saddr only when it's 0 Now sctp_transport_pmtu() passes transport->saddr into .get_dst() to set flow sport from 'saddr'. However, transport->saddr is set only when transport->dst exists in sctp_transport_route(). If sctp_transport_pmtu() is called without transport->saddr set, like when transport->dst doesn't exists, the flow sport will be set to 0 from transport->saddr, which will cause a wrong route to be got. Commit 6e91b578bf3f ("sctp: re-use sctp_transport_pmtu in sctp_transport_route") made the issue be triggered more easily since sctp_transport_pmtu() would be called in sctp_transport_route() after that. In gerneral, fl4->fl4_sport should always be set to htons(asoc->base.bind_addr.port), unless transport->asoc doesn't exist in sctp_v4/6_get_dst(), which is the case: sctp_ootb_pkt_new() -> sctp_transport_route() For that, we can simply handle it by setting flow sport from saddr only when it's 0 in sctp_v4/6_get_dst().

However, 'retval' transport belong to the new asoc, which is a different one from 'chunk' transport's asoc. It will cause that the 'retval' chunk gets set with a wrong transport. Later when sending it and because of Commit b9fd683982c9 ("sctp: add sctp_packet_singleton"), sctp_packet_singleton() will set some fields, like vtag to 'retval' chunk from that wrong transport's asoc.

a3c5e2c drm/msm: Fix A6XX support for opp-level The bindings for Qualcomm opp levels changed after being Acked but before landing. Thus the code in the GPU driver that was relying on the old bindings is now broken. Let's change the code to match the new bindings by adjusting the old string 'qcom,level' to the new string 'opp-level'. See the patch ("dt-bindings: opp: Introduce opp-level bindings"). NOTE: we will do additional cleanup to totally remove the string from the code and use the new dev_pm_opp_get_level() but we'll do it in a future patch. This will facilitate getting the important code fix in sooner without having to deal with cross-maintainer dependencies. This patch needs to land before the patch ("arm64: dts: sdm845: Add gpu and gmu device nodes") since if a tree contains the device tree patch but not this one you'll get a crash at bootup.

acc58d0 CIFS: Fix possible hang during async MTU reads and writes When doing MTU i/o we need to leave some credits for possible reopen requests and other operations happening in parallel. Currently we leave 1 credit which is not enough even for reopen only: we need at least 2 credits if durable handle reconnect fails. Also there may be other operations at the same time including compounding ones which require 3 credits at a time each. Fix this by leaving 8 credits which is big enough to cover most scenarios. Was able to reproduce this when server was configured to give out fewer credits than usual. The proper fix would be to reconnect a file handle first and then obtain credits for an MTU request but this leads to bigger code changes and should happen in other patches.

73aaf92 cifs: fix memory leak of an allocated cifs_ntsd structure The call to SMB2_queary_acl can allocate memory to pntsd and also return a failure via a call to SMB2_query_acl (and then query_info). This occurs when query_info allocates the structure and then in query_info the call to smb2_validate_and_copy_iov fails. Currently the failure just returns without kfree'ing pntsd hence causing a memory leak. Currently, *data is allocated if it's not already pointing to a buffer, so it needs to be kfree'd only if was allocated in query_info, so the fix adds an allocated flag to track this. Also set *dlen to zero on an error just to be safe since *data is kfree'd. Also set errno to -ENOMEM if the allocation of *data fails.

78a61cd nvme-multipath: drop optimization for static ANA group IDs Bit 6 in the ANACAP field is used to indicate that the ANA group ID doesn't change while the namespace is attached to the controller. There is an optimisation in the code to only allocate space for the ANA group header, as the namespace list won't change and hence would not need to be refreshed. However, this optimisation was never carried over to the actual workflow, which always assumes that the buffer is large enough to hold the ANA header _and_ the namespace list.

Instead, keep track of how many default/read/poll queues we actually allocated (rather than asked by the user) and use that to assign our queue mappings.
