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 ]

veth.sh is a shell script that uses /bin/sh; some distro (Ubuntu for

following error:
# ./veth.sh: 21: local: -r: bad variable name
# ./veth.sh: 21: local: -r: bad variable name
This happens because dash doesn't support the option "-r" with local.
Moreover, in case of missing bpf object, the script is exiting -1, that
is an illegal number for dash:

With the MMCR0 control bit (PMCCEXT) in ISA v3.1, read access to
group B registers is restricted when MMCR0 PMCC=0b00. In other
platforms (like power9), the older behaviour works where group B
PMU SPRs are readable.
Patch creates a selftest which verifies that the test takes a
SIGILL when attempting to read PMU registers via helper function
"dump_ebb_state" for ISA v3.1.

The "no_handler_test" in ebb selftests attempts to read the PMU
registers twice via helper function "dump_ebb_state". First dump is
just before closing of event and the second invocation is done after
closing of the event. The original intention of second
dump_ebb_state was to dump the state of registers at the end of
the test when the counters are frozen. But this will be achieved
with the first call itself since sample period is set to low value
and PMU will be frozen by then. Hence patch removes the
dump which was done before closing of the event.

Migrate to kselftest harness. Use a fixture test with enclave initialized
and de-initialized for each of the existing three tests, in other words:
1. One FIXTURE() for managing the enclave life-cycle.
2. Three TEST_F()'s, one for each test case.
Dump lines of /proc/self/maps matching "sgx" in FIXTURE_SETUP() as this
can be very useful debugging information later on.
Amended commit log:
This migration changes the output of this test. Instead of skipping
the tests if open /dev/sgx_enclave fails, it will run all the tests
and report failures on all of them.

In almost all cases from test_verifier that have been changed in here, we've
had an unreachable path with a load from a register which has an invalid
address on purpose. This was basically to make sure that we never walk this
path and to have the verifier complain if it would otherwise. Change it to
match on the right error for unprivileged given we now test these paths
under speculative execution.
There's one case where we match on exact # of insns_processed. Due to the
extra path, this will of course mismatch on unprivileged. Thus, restrict the
test->insn_processed check to privileged-only.
In one other case, we result in a 'pointer comparison prohibited' error. This
is similarly due to verifying an 'invalid' branch where we end up with a value
pointer on one side of the comparison.

Oliver reported a use case where deleting a VRF device can hang
waiting for the refcnt to drop to 0. The root cause is that the dst
is allocated against the VRF device but cached on the loopback
device.
The use case (added to the selftests) has an implicit VRF crossing
due to the ordering of the FIB rules (lookup local is before the
l3mdev rule, but the problem occurs even if the FIB rules are
re-ordered with local after l3mdev because the VRF table does not
have a default route to terminate the lookup). The end result is
is that the FIB lookup returns the loopback device as the nexthop,
but the ingress device is in a VRF. The mismatch causes the dst
alloc against the VRF device but then cached on the loopback.
The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu):
pick the dst alloc device based the fib lookup result but with checks
that the result has a nexthop device (e.g., not an unreachable or
prohibit entry).

Add the infrastructure needed to enable exception handling in aarch64

handler which aborts the test, just like x86. These handlers can be
overridden by calling vm_install_exception_handler(vector) or
vm_install_sync_handler(vector, ec). The unhandled exception reporting
from the guest is done using the ucall type introduced in a previous

x86, the only arch implementing exception handling, reports unhandled

ucall already does.

reporting to use it instead of port IO. This new ucall type will be

The guest in sync_regs_test does raw ucalls by directly accessing the
ucall IO port. It makes these ucalls without setting %rdi to a `struct
ucall`, which is what a ucall uses to pass messages. The issue is that
if the host did a get_ucall (the receiver side), it would try to access
the `struct ucall` at %rdi=0 which would lead to an error ("No mapping
for vm virtual address, gva: 0x0").
This issue is currently benign as there is no get_ucall in
sync_regs_test; however, that will change in the next commit as it
changes the unhandled exception reporting mechanism to use ucalls. In
that case, every vcpu_run is followed by a get_ucall to check if the
guest is trying to report an unhandled exception.
Fix this in advance by setting %rdi to a UCALL_NONE struct ucall for the
sync_regs_test guest.
