Linus Torvalds c884d8ac7f SPDX update for 5.2-rc6
Another round of SPDX updates for 5.2-rc6
 
 Here is what I am guessing is going to be the last "big" SPDX update for
 5.2.  It contains all of the remaining GPLv2 and GPLv2+ updates that
 were "easy" to determine by pattern matching.  The ones after this are
 going to be a bit more difficult and the people on the spdx list will be
 discussing them on a case-by-case basis now.
 
 Another 5000+ files are fixed up, so our overall totals are:
 	Files checked:            64545
 	Files with SPDX:          45529
 
 Compared to the 5.1 kernel which was:
 	Files checked:            63848
 	Files with SPDX:          22576
 This is a huge improvement.
 
 Also, we deleted another 20000 lines of boilerplate license crud, always
 nice to see in a diffstat.

Paolo Bonzini 9fd5887726 KVM: nVMX: reorganize initial steps of vmx_set_nested_state
Commit 332d079735 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS
state before setting new state", 2019-05-02) broke evmcs_test because the
eVMCS setup must be performed even if there is no VMXON region defined,
as long as the eVMCS bit is set in the assist page.

While the simplest possible fix would be to add a check on
kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that
covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.

Instead, this patch moves checks earlier in the function and
conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that
vmx_set_nested_state always goes through vmx_leave_nested
and nested_enable_evmcs.

Aaron Lewis 9dba988edb tests: kvm: Check for a kernel warning
When running with /sys/module/kvm_intel/parameters/unrestricted_guest=N,
test that a kernel warning does not occur informing us that
vcpu->mmio_needed=1.  This can happen when KVM_RUN is called after a
triple fault.
This test was made to detect a bug that was reported by Syzkaller
(https://groups.google.com/forum/#!topic/syzkaller/lHfau8E3SOE) and
fixed with commit bbeac2830f ("KVM: X86: Fix residual mmio emulation

Liran Alon 6ca00dfafd KVM: x86: Modify struct kvm_nested_state to have explicit fields for data
Improve the KVM_{GET,SET}_NESTED_STATE structs by detailing the format
of VMX nested state data in a struct.

In order to avoid changing the ioctl values of
KVM_{GET,SET}_NESTED_STATE, there is a need to preserve
sizeof(struct kvm_nested_state). This is done by defining the data
struct as "data.vmx[0]". It was the most elegant way I found to
preserve struct size while still keeping struct readable and easy to
maintain. It does have a misfortunate side-effect that now it has to be
accessed as "data.vmx[0]" rather than just "data.vmx".

Because we are already modifying these structs, I also modified the
following:
* Define the "format" field values as macros.
* Rename vmcs_pa to vmcs12_pa for better readability.

Dan Williams 50f44ee724 mm/devm_memremap_pages: fix final page put race
Logan noticed that devm_memremap_pages_release() kills the percpu_ref
drops all the page references that were acquired at init and then
immediately proceeds to unplug, arch_remove_memory(), the backing pages
for the pagemap.  If for some reason device shutdown actually collides
with a busy / elevated-ref-count page then arch_remove_memory() should
be deferred until after that reference is dropped.

As it stands the "wait for last page ref drop" happens *after*
devm_memremap_pages_release() returns, which is obviously too late and
can lead to crashes.

Fix this situation by assigning the responsibility to wait for the
percpu_ref to go idle to devm_memremap_pages() with a new ->cleanup()
callback.  Implement the new cleanup callback for all
devm_memremap_pages() users: pmem, devdax, hmm, and p2pdma.

Jonathan Lemon da2577fdd0 bpf: lpm_trie: check left child of last leftmost node for NULL
If the leftmost parent node of the tree has does not have a child
on the left side, then trie_get_next_key (and bpftool map dump) will
not look at the child on the right.  This leads to the traversal
missing elements.

Lookup is not affected.

Update selftest to handle this case.

Reproducer:

 bpftool map create /sys/fs/bpf/lpm type lpm_trie key 6 \
     value 1 entries 256 name test_lpm flags 1
 bpftool map update pinned /sys/fs/bpf/lpm key  8 0 0 0  0   0 value 1
 bpftool map update pinned /sys/fs/bpf/lpm key 16 0 0 0  0 128 value 2
 bpftool map dump   pinned /sys/fs/bpf/lpm

Returns only 1 element. (2 expected)

1) Fix several bugs in riscv64 JIT code emission which forgot to clear high
   32-bits for alu32 ops, from Björn and Luke with selftests covering all
   relevant BPF alu ops from Björn and Jiong.

2) Two fixes for UDP BPF reuseport that avoid calling the program in case of
   __udp6_lib_err and UDP GRO which broke reuseport_select_sock() assumption
   that skb->data is pointing to transport header, from Martin.

3) Two fixes for BPF sockmap: a use-after-free from sleep in psock's backlog
   workqueue, and a missing restore of sk_write_space when psock gets dropped,
   from Jakub and John.

4) Fix unconnected UDP sendmsg hook API which is insufficient as-is since it
   breaks standard applications like DNS if reverse NAT is not performed upon
   receive, from Daniel.

5) Fix an out-of-bounds read in __bpf_skc_lookup which in case of AF_INET6
   fails to verify that the length of the tuple is long enough, from Lorenz.

6) Fix libbpf's libbpf__probe_raw_btf to return an fd instead of 0/1 (for
   {un,}successful probe) as that is expected to be propagated as an fd to
   load_sk_storage_btf() and thus closing the wrong descriptor otherwise,
   from Michal.

7) Fix bpftool's JSON output for the case when a lookup fails, from Krzesimir.

8) Minor misc fixes in docs, samples and selftests, from various others.

Krzesimir Nowak 1884c06657 tools: bpftool: Fix JSON output when lookup fails
In commit 9a5ab8bf1d ("tools: bpftool: turn err() and info() macros
into functions") one case of error reporting was special cased, so it
could report a lookup error for a specific key when dumping the map
element. What the code forgot to do is to wrap the key and value keys
into a JSON object, so an example output of pretty JSON dump of a
sockhash map (which does not support looking up its values) is:

[
    "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00"
    ],
    "value": {
        "error": "Operation not supported"
    },
    "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01"
    ],
    "value": {
        "error": "Operation not supported"
    }
]

Note the key-value pairs inside the toplevel array. They should be
wrapped inside a JSON object, otherwise it is an invalid JSON. This
commit fixes this, so the output now is:

[{
        "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00"
        ],
        "value": {
            "error": "Operation not supported"
        }
    },{
        "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01"
        ],
        "value": {
            "error": "Operation not supported"
        }
    }
]

Merge tag 'pidfd-fixes-v5.2-rc4' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux

Pull pidfd fixes from Christian Brauner:
 "The contains two small patches to the pidfd samples and test binaries
  respectively.

  They were lacking appropriate ifdefines for __NR_pidfd_send_signal and
  could hence lead to compilation errors when that was not defined.

  This was spotted on mips independently by Guenter Roeck (who was kind
  enough to send a fix for the samples binary) and Arnd who spotted it
  in linux-next.

  Apart from these two patches, there's also a patch to update the
  comments for the pidfd_send_signal() syscall which were slightly
  wrong/inconsistenly worded"
