vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.
When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.
Fix vdso_test_abi verifying the return code of each test separately.

Report mincore.check_file_mmap as SKIP instead of FAIL if the underlying
filesystem lacks support of O_TMPFILE or fallocate since such failures
are not really related to mincore functionality.

Recursive make commands should always use the variable MAKE, not the
explicit command name ‘make’. This has benefits and removes the
following warning when multiple jobs are used for the build:
make[2]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.

If zram-generator package is installed and works, then we can not remove
zram module because zram swap is being used. This case needs a clean zram
environment, change this test by using hot_add/hot_remove interface. So
even zram device is being used, we still can add zram device and remove
them in cleanup.
The two interface was introduced since kernel commit 6566d1a32bf7("zram:
add dynamic device add/remove functionality") in v4.2-rc1. If kernel
supports these two interface, we use hot_add/hot_remove to slove this
problem, if not, just check whether zram is being used or built in, then
skip it on old kernel.

zram01 uses `free -m` to measure zram memory usage. The results are no
sense because they are polluted by all running processes on the system.
We Should only calculate the free memory delta for the current process.
So use the third field of /sys/block/zram<id>/mm_stat to measure memory
usage instead. The file is available since kernel 4.1.
orig_data_size(first): uncompressed size of data stored in this disk.
compr_data_size(second): compressed size of data stored in this disk
mem_used_total(third): the amount of memory allocated for this disk
Also remove useless zram cleanup call in zram_fill_fs and so we don't
need to cleanup zram twice if fails.

Since commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram
has switched to per-cpu streams. Even kernel still keep this interface for
some reasons, but writing to max_comp_stream doesn't take any effect. So
skip it on newer kernel ie 4.7.
The code that comparing kernel version is from xfstests testsuite ext4/053.

We have some many cases that will create child process as well, such as
pidfd_wait. Previously, we will signal/kill the parent process when it
is time out, but this signal will not be sent to its child process. In
such case, if child process doesn't terminate itself, ksefltest framework
will hang forever.
Here we group all its child processes so that kill() can signal all of
them in timeout.

Use 'tee' to send the test output to stdout in addition to the current
output file. This makes the output easier to handle in automated test
systems and is superior to only later dumping the output file contents
to stdout, since this way the test output can be interleaved with other
log messages, like from the kernel, so that chronology is preserved,
making it easier to detect issues.

The timeout setting for the rtc kselftest is currently 90 seconds. This
setting is used by the kselftest runner to stop running a test if it
takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are
set to the next beginning of the minute, so each of these test cases may
take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst
case, when using the kselftest runner, the timeout value should be
increased to at least 120. Set it to 180, so there's some additional
slack.
Correct operation can be tested by running the following command right
after the start of a minute (low second count), and checking that all
test cases run:
./run_kselftest.sh -c rtc

There is no need for tests other than amx_test to enable dynamic xsave
states. Remove the call to vm_xsave_req_perm from generic code,
and move it inside the test. While at it, allow customizing the bit
that is requested, so that future tests can use it differently.

Don't skip the vmcall() in l2_guest_code() prior to re-entering L2, doing
so will result in L2 running to completion, popping '0' off the stack for
RET, jumping to address '0', and ultimately dying with a triple fault
shutdown.
It's not at all obvious why the test re-enters L2 and re-executes VMCALL,
but presumably it serves a purpose. The VMX path doesn't skip vmcall(),
and the test can't possibly have passed on SVM, so just do what VMX does.

MPJ ipv6 selftests currently lack per link route to the server
net. Additionally, ipv6 subflows endpoints are created without any
interface specified. The end-result is that in ipv6 self-tests
subflows are created all on the same link, leading to expected delays
and sporadic self-tests failures.
Fix the issue by adding the missing setup bits.

Add a VMX specific test to verify that KVM doesn't explode if userspace
attempts KVM_RUN when emulation is required with a pending exception.
KVM VMX's emulation support for !unrestricted_guest punts exceptions to
userspace instead of attempting to synthesize the exception with all the
correct state (and stack switching, etc...).
Punting is acceptable as there's never been a request to support
injecting exceptions when emulating due to invalid state, but KVM has
historically assumed that userspace will do the right thing and either
clear the exception or kill the guest. Deliberately do the opposite and
attempt to re-enter the guest with a pending exception and emulation
required to verify KVM continues to punt the combination to userspace,
e.g. doesn't explode, WARN, etc...

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, bpf.
Quite a handful of old regression fixes but most of those are
pre-5.16.
Current release - regressions:
- fix memory leaks in the skb free deferral scheme if upper layer
protocols are used, i.e. in-kernel TCP readers like TLS
Current release - new code bugs:
- nf_tables: fix NULL check typo in _clone() functions
- change the default to y for Vertexcom vendor Kconfig
- a couple of fixes to incorrect uses of ref tracking
- two fixes for constifying netdev->dev_addr
Previous releases - regressions:
- bpf:
- various verifier fixes mainly around register offset handling
when passed to helper functions
- fix mount source displayed for bpffs (none -> bpffs)
- bonding:
- fix extraction of ports for connection hash calculation
- fix bond_xmit_broadcast return value when some devices are down
- phy: marvell: add Marvell specific PHY loopback
- sch_api: don't skip qdisc attach on ingress, prevent ref leak
- htb: restore minimal packet size handling in rate control
- sfp: fix high power modules without diagnostic monitoring
- mscc: ocelot:
- don't let phylink re-enable TX PAUSE on the NPI port
- don't dereference NULL pointers with shared tc filters
- smsc95xx: correct reset handling for LAN9514
- cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
- phy: micrel: use kszphy_suspend/_resume for irq aware devices,
avoid races with the interrupt
Previous releases - always broken:
- xdp: check prog type before updating BPF link
- smc: resolve various races around abnormal connection termination
- sit: allow encapsulated IPv6 traffic to be delivered locally
- axienet: fix init/reset handling, add missing barriers, read the
right status words, stop queues correctly
- add missing dev_put() in sock_timestamping_bind_phc()
Misc:
- ipv4: prevent accidentally passing RTO_ONLINK to
ip_route_output_key_hash() by sanitizing flags
- ipv4: avoid quadratic behavior in netns dismantle
- stmmac: dwmac-oxnas: add support for OX810SE
- fsl: xgmac_mdio: add workaround for erratum A-009885"

Add two tests, one which asserts that ring buffer memory can be passed to
other helpers for populating its entry area, and another one where verifier
rejects different type of memory passed to bpf_ringbuf_submit().

Add a check to the xdp_link selftest that the kernel rejects replacing an
XDP program with a different program type on link update.
v2:
- Split this out into its own patch.

Convert the selftest to use the preferred ASSERT_* macros instead of the
deprecated CHECK().
v2:
- Don't add if statements around checks if they weren't there before.

timeout in settings is used by each case under the same directory, so
it should adapt to the maximum runtime.
A normally running net/fib_nexthops.sh may be killed by this unsuitable
timeout. Furthermore, since the defect[1] of kselftests framework,
net/fib_nexthops.sh which might take at least (300 * 4) seconds would
block the whole kselftests framework previously.
$ git grep -w 'sleep 300' tools/testing/selftests/net
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
tools/testing/selftests/net/fib_nexthops.sh: sleep 300
Enlarge the timeout by plus 300 based on the obvious largest runtime
to avoid the blocking.
