Use memslot '0' for all vm_vaddr_alloc() calls when loading the test

Commit 22f232d134e1 ("KVM: selftests: x86: Set supported CPUIDs on
default VM") moved vcpu_set_cpuid into vm_create_with_vcpus, but
dirty_log_test doesn't use it to create vm. So vcpu's CPUIDs is
not set, the guest's pa_bits in kvm would be smaller than the
value queried by userspace.
However, the dirty track memory slot is in the highest GPA, the
reserved bits in gpte would be set with wrong pa_bits.
For shadow paging, page fault would fail in permission_fault and
be injected into guest. Since guest doesn't have idt, it finally
leads to vm_exit for triple fault.
Move vcpu_set_cpuid into vm_vcpu_add_default to set supported
CPUIDs on default vcpu, since almost all tests need it.

The SGX selftests can fail for a bunch of non-obvious reasons
like 'noexec' permissions on /dev (which is the default *EVERYWHERE*
it seems).
A new test mistakenly also looked for +x permission on the
/dev/sgx_enclave. File execute permissions really only apply to
the ability of execve() to work on a file, *NOT* on the ability
for an application to map the file with PROT_EXEC. SGX needs to
mmap(PROT_EXEC), but doesn't need to execve() the device file.
Remove the check.

The following pull-request contains BPF updates for your *net* tree.
We've added 14 non-merge commits during the last 6 day(s) which contain
a total of 13 files changed, 137 insertions(+), 64 deletions(-).
Note that when you merge net into net-next, there is a small merge conflict
between 9f2470fbc4cb ("skmsg: Improve udp_bpf_recvmsg() accuracy") from bpf
with c49661aa6f70 ("skmsg: Remove unused parameters of sk_msg_wait_data()")
from net-next. Resolution is to: i) net/ipv4/udp_bpf.c: take udp_msg_wait_data()
and remove err parameter from the function, ii) net/ipv4/tcp_bpf.c: take
tcp_msg_wait_data() and remove err parameter from the function, iii) for
net/core/skmsg.c and include/linux/skmsg.h: remove the sk_msg_wait_data()
implementation and its prototype in header.
The main changes are:
1) Fix BPF poke descriptor adjustments after insn rewrite, from John Fastabend.
2) Fix regression when using BPF_OBJ_GET with non-O_RDWR flags, from Maciej Żenczykowski.
3) Various bug and error handling fixes for UDP-related sock_map, from Cong Wang.

According to a comment in commit 99513cfa16c6 ("selftest: Fixes for
icmp_redirect test") the test "IPv6: mtu exception plus redirect" is
expected to fail, because of a bug in the IPv6 logic that hasn't been
fixed yet apparently.
We should probably consider this failure as an "expected failure",
therefore change the script to return XFAIL for that particular test and
also report the total amount of expected failures at the end of the run.

There are three different strategies to uniquely identify a futex in the
kernel:
- Private futexes: uses the pointer to mm_struct and the page address
- Shared futexes: checks if the page containing the address is a PageAnon:
- If it is, uses the same data as a private futexes
- If it isn't, uses an inode sequence number from struct inode and
the page's index
Create a selftest to check those three paths and basic wait/wake
mechanism.

Selftest updates from Andrew Jones, fixing the sysgreg list
expectations by dealing with multiple configurations, such
as with or without a PMU.
* kvm-arm64/selftest/sysreg-list-fix:
KVM: arm64: Update MAINTAINERS to include selftests
KVM: arm64: selftests: get-reg-list: Split base and pmu registers

KVM: arm64: selftests: get-reg-list: Prepare to run multiple configs at once
KVM: arm64: selftests: get-reg-list: Introduce vcpu configs
Since KVM commit 11663111cd49 ("KVM: arm64: Hide PMU registers from
userspace when not available") the get-reg-list* tests have been
failing with
...
... There are 74 missing registers.
The following lines are missing registers:
...
where the 74 missing registers are all PMU registers. This isn't a
bug in KVM that the selftest found, even though it's true that a
KVM userspace that wasn't setting the KVM_ARM_VCPU_PMU_V3 VCPU
flag, but still expecting the PMU registers to be in the reg-list,
would suddenly no longer have their expectations met. In that case,
the expectations were wrong, though, so that KVM userspace needs to
be fixed, and so does this selftest. The fix for this selftest is to
pull the PMU registers out of the base register sublist into their
own sublist and then create new, pmu-enabled vcpu configs which can
be tested.

otherwise.

We already break register lists into sublists that get selected based
on vcpu config. However, since we only had two configs (vregs and sve),
we didn't structure the code very well to manage them. Restructure it
now to more cleanly handle register sublists that are dependent on the
vcpu config.
This patch has no intended functional change (except for the vcpu
config name now being prepended to all output).

We use non-blocking sockets for testing sockmap redirections,
and got some random EAGAIN errors from UDP tests.
There is no guarantee the packet would be immediately available
to receive as soon as it is sent out, even on the local host.
For UDP, this is especially true because it does not lock the
sock during BH (unlike the TCP path). This is probably why we
only saw this error in UDP cases.
No matter how hard we try to make the queue empty check accurate,
it is always possible for recvmsg() to beat ->sk_data_ready().
Therefore, we should just retry in case of EAGAIN.

This adds a new icmp.sh selftest for testing that the kernel will respond
correctly with an ICMP unreachable message with the dummy (192.0.0.8)
source address when there are no IPv4 addresses configured to use as source
addresses.

This patch added a new argument "-C" for the mptcp_join.sh script to set
the sysctl checksum_enabled to 1 in ns1 and ns2 to enable the data
checksum.
In chk_join_nr, check the counter of the mib for the data checksum.
Also added a new argument "-S" for the mptcp_join.sh script to start the
test cases that verify the checksum handshake:
* Sender and listener both have checksums off
* Sender and listener both have checksums on
* Sender checksums off, listener checksums on
* Sender checksums on, listener checksums off
The output looks like this:
01 checksum test 0 0 sum[ ok ] - csum [ ok ]
02 checksum test 1 1 sum[ ok ] - csum [ ok ]
03 checksum test 0 1 sum[ ok ] - csum [ ok ]
04 checksum test 1 0 sum[ ok ] - csum [ ok ]
05 no JOIN syn[ ok ] - synack[ ok ] - ack[ ok ]
sum[ ok ] - csum [ ok ]
06 single subflow, limited by client syn[ ok ] - synack[ ok ] - ack[ ok ]
sum[ ok ] - csum [ ok ]

migrate_reuseport.c selftest relies on having TCP_FASTOPEN_CONNECT defined in
system-wide netinet/tcp.h. Selftests can use up-to-date uapi/linux/tcp.h, but
that one doesn't have SOL_TCP. So instead of switching everything to uapi
header, add #define for TCP_FASTOPEN_CONNECT to fix the build.

Somehow test_progs.h was being included by the existing rule:
/test_progs*
This is bad because:
1) test_progs.h is a checked in file
2) grep-like tools like ripgrep[0] respect gitignore and
test_progs.h was being hidden from searches

that doesn't support such operators.
