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.

Make the default .kunitconfig (specified in
arch/um/configs/kunit_defconfig) specify CONFIG_KUNIT_ALL_TESTS by
default. KUNIT_ALL_TESTS runs all tests which have satisfied
dependencies in the current .config (which would be the architecture
defconfig).
Currently, the default .kunitconfig enables only the example tests and
KUnit's own tests. While this does provide a good example of what a
.kunitconfig for running a few individual tests should look like, it
does mean that kunit_tool runs a pretty paltry collection of tests by
default.
The example tests' config entry (CONFIG_KUNIT_EXAMPLE_TEST=y) continues
to be included -- despite now being redundant -- to provide an example
of how tests are enabled when KUNIT_ALL_TESTS is disabled.
A default run of ./tools/testing/kunit/kunit.py run now runs 70 tests
instead of 14.

Currently, the KUNIT_EXPECT_STREQ() and related macros assign both
string arguments to variables of their own type (via typeof()). This
seems to be to prevent the macro argument from being evaluated multiple
times.
However, this doesn't work if one of these is a fixed-length character
array, rather than a character pointer, as (for example) char[16] will
always allocate a new string.
By always using 'const char*' (the type strcmp expects), we're always
just taking a pointer to the string, which works even with character
arrays.

The use of typecheck() in KUNIT_EXPECT_EQ() and friends is causing more
problems than I think it's worth. Things like enums need to have their
values explicitly cast, and literals all need to be very precisely
typed, else a large warning will be printed.
While typechecking does have its uses, the additional overhead of having
lots of needless casts -- combined with the awkward error messages which
don't mention which types are involved -- makes tests less readable and
more difficult to write.
By removing the typecheck() call, the two arguments still need to be of
compatible types, but don't need to be of exactly the same time, which
seems a less confusing and more useful compromise.

There is no reason to do an extra XRSTOR from init_fpstate for feature
bits which have been cleared by user space in the FX magic xfeatures
storage.
Just clear them in the task's XSTATE header and do a full restore which
will put these cleared features into init state.
There is no real difference in performance because the current code
already does a full restore when the xfeatures bits are preserved as the
signal frame setup has stored them, which is the full UABI feature set.

pull-request: bpf 2021-06-23
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 9f2470fbc4 ("skmsg: Improve udp_bpf_recvmsg() accuracy") from bpf
with c49661aa6f ("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.

I see no reason why max_dst_opts_cnt and max_hbh_opts_cnt

The other sysctls (max_dst_opts_len & max_hbh_opts_len)

Note: it is not clear why ipv6_destopt_rcv() use two ways to
get to the netns :
1) dev_net(dst->dev)
Originally used to increment IPSTATS_MIB_INHDRERRORS
2) dev_net(skb->dev)

The Broadcom UniMAC MDIO bus from mdio-bcm-unimac module comes too late.
So, GENET cannot find the ethernet PHY on UniMAC MDIO bus. This leads
GENET fail to attach the PHY as following log:
bcmgenet fd580000.ethernet: GENET 5.0 EPHY: 0x0000
...
could not attach to PHY
bcmgenet fd580000.ethernet eth0: failed to connect to PHY
uart-pl011 fe201000.serial: no DMA platform data
libphy: bcmgenet MII bus: probed
...
unimac-mdio unimac-mdio.-19: Broadcom UniMAC MDIO bus
This patch adds the soft dependency to load mdio-bcm-unimac module
before genet module to avoid the issue.

The commit 3c9ef511b9 ("bonding: avoid adding slave device with
IFF_MASTER flag") fix a crash when add slave device with IFF_MASTER,
but it rejects the scenario of nested bonding device.
As Eric Dumazet described: since there indeed is a usage scenario about
nesting bonding, we should not break it.
So we add a new judgment condition to allow nesting of bonding device.

We'll be replacing :doc:`foo` references to
Documentation/foo.rst. Yet, here it happens inside a table.
Doing a search-and-replace would break it.
Yet, as there's no good reason to use a table there,
let's just convert it into a list.

This commit adds two stats for the socket migration feature to evaluate the
effectiveness: LINUX_MIB_TCPMIGRATEREQ(SUCCESS|FAILURE).
If the migration fails because of the own_req race in receiving ACK and
sending SYN+ACK paths, we do not increment the failure stat. Then another
CPU is responsible for the req.

TCP checksums on received packets may be set to NULL by the sender if CSO
is enabled. The hypervisor flags these packets as check-sum-ok and the
skb is then flagged CHECKSUM_UNNECESSARY. If these packets are then
forwarded the sender will not request CSO due to the CHECKSUM_UNNECESSARY
flag. The result is a TCP packet sent with a bad checksum. This change
sets up CHECKSUM_PARTIAL on these packets causing the sender to correctly
request CSUM offload.

According to a comment in commit 99513cfa16 ("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.

Some optimization for lockless qdisc
Patch 1: remove unnecessary seqcount operation.
Patch 2: implement TCQ_F_CAN_BYPASS.
Patch 3: remove qdisc->empty.
Performance data for pktgen in queue_xmit mode + dummy netdev
with pfifo_fast:
threads unpatched patched delta
1 2.60Mpps 3.21Mpps +23%
2 3.84Mpps 5.56Mpps +44%
4 5.52Mpps 5.58Mpps +1%
8 2.77Mpps 2.76Mpps -0.3%
16 2.24Mpps 2.23Mpps -0.4%
Performance for IP forward testing: 1.05Mpps increases to
1.16Mpps, about 10% improvement.
V3: Add 'Acked-by' from Jakub and 'Tested-by' from Vladimir,
and resend based on latest net-next.
V2: Adjust the comment and commit log according to discussion
in V1.
V1: Drop RFC tag, add nolock_qdisc_is_empty() and do the qdisc
empty checking without the protection of qdisc->seqlock to
aviod doing unnecessary spin_trylock() for contention case.
RFC v4: Use STATE_MISSED and STATE_DRAINING to indicate non-empty
qdisc, and add patch 1 and 3.
