Nick Desaulniers 4f4ef354f9 selftests: sigaltstack: fix -Wuninitialized
[ Upstream commit 05107edc91 ]

Building sigaltstack with clang via:
$ ARCH=x86 make LLVM=1 -C tools/testing/selftests/sigaltstack/

produces the following warning:
  warning: variable 'sp' is uninitialized when used here [-Wuninitialized]
  if (sp < (unsigned long)sstack ||
      ^~

Clang expects these to be declared at global scope; we've fixed this in
the kernel proper by using the macro `current_stack_pointer`. This is
defined in different headers for different target architectures, so just
create a new header that defines the arch-specific register names for
the stack pointer register, and define it for more targets (at least the
ones that support current_stack_pointer/ARCH_HAS_CURRENT_STACK_POINTER).

Hangbin Liu e4e5006c13 selftests: nft_nat: ensuring the listening side is up before starting the client
[ Upstream commit 2067e7a00a ]

The test_local_dnat_portonly() function initiates the client-side as
soon as it sets the listening side to the background. This could lead to
a race condition where the server may not be ready to listen. To ensure
that the server-side is up and running before initiating the
client-side, a delay is introduced to the test_local_dnat_portonly()
function.

Before the fix:
  # ./nft_nat.sh
  PASS: netns routing/connectivity: ns0-rthlYrBU can reach ns1-rthlYrBU and ns2-rthlYrBU
  PASS: ping to ns1-rthlYrBU was ip NATted to ns2-rthlYrBU

Steven Rostedt 18d347d1b0 ktest.pl: Add RUN_TIMEOUT option with default unlimited
commit 4e7d2a8f0b upstream.

There is a disconnect between the run_command function and the
wait_for_input. The wait_for_input has a default timeout of 2 minutes. But
if that happens, the run_command loop will exit out to the waitpid() of
the executing command. This fails in that it no longer monitors the
command, and also, the ssh to the test box can hang when its finished, as
it's waiting for the pipe it's writing to to flush, but the loop that
reads that pipe has already exited, leaving the command stuck, and the
test hangs.

Instead, make the default "wait_for_input" of the run_command infinite,
and allow the user to override it if they want with a default timeout
option "RUN_TIMEOUT".

But this fixes the hang that happens when the pipe is full and the ssh
session never exits.

Steven Rostedt 150ee1fc90 ktest.pl: Fix missing "end_monitor" when machine check fails
commit e8bf9b98d4 upstream.

In the "reboot" command, it does a check of the machine to see if it is
still alive with a simple "ssh echo" command. If it fails, it will assume
that a normal "ssh reboot" is not possible and force a power cycle.

In this case, the "start_monitor" is executed, but the "end_monitor" is
not, and this causes the screen will not be given back to the console. That
is, after the test, a "reset" command needs to be performed, as "echo" is
turned off.

Roxana Nicolescu c82ca67ca0 selftest: fib_tests: Always cleanup before exit
[ Upstream commit b60417a9f2 ]

Usage of `set -e` before executing a command causes immediate exit
on failure, without cleanup up the resources allocated at setup.
This can affect the next tests that use the same resources,
leading to a chain of failures.

A simple fix is to always call cleanup function when the script exists.
This approach is already used by other existing tests.

Jakub Sitnicki c31985922e selftests/net: Interpret UDP_GRO cmsg data as an int value
[ Upstream commit 436864095a ]

Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:

  recvmsg(8, {msg_name=...,
              msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
              msg_iovlen=1,
              msg_control=[{cmsg_len=20,         <-- sizeof(cmsghdr) + 4
                            cmsg_level=SOL_UDP,
                            cmsg_type=0x68}],    <-- UDP_GRO
                            msg_controllen=24,
                            msg_flags=0}, 0) = 11200

Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

Andrei Gherzan aed972fbf6 selftests: net: udpgso_bench_tx: Cater for pending datagrams zerocopy benchmarking
[ Upstream commit 329c9cd769 ]

The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).

This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).

Andrei Gherzan df1213a267 selftests: net: udpgso_bench: Fix racing bug between the rx/tx programs
[ Upstream commit dafe93b9ee ]

"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs
subsequently and while doing so, there is a chance that the rx one is not
ready to accept socket connections. This racing bug could fail the test
with at least one of the following:

./udpgso_bench_tx: connect: Connection refused
./udpgso_bench_tx: sendmsg: Connection refused
./udpgso_bench_tx: write: Connection refused

This change addresses this by making udpgro_bench.sh wait for the rx
program to be ready before firing off the tx one - up to a 10s timeout.

Steven Rostedt 3de2c36283 ktest.pl minconfig: Unset configs instead of just removing them
commit ef784eebb5 upstream.

After a full run of a make_min_config test, I noticed there were a lot of
CONFIGs still enabled that really should not be. Looking at them, I
noticed they were all defined as "default y". The issue is that the test
simple removes the config and re-runs make oldconfig, which enables it
again because it is set to default 'y'. Instead, explicitly disable the
config with writing "# CONFIG_FOO is not set" to the file to keep it from
being set again.

With this change, one of my box's minconfigs went from 768 configs set,
down to 521 configs set.

Florian Westphal d4145d028a netfilter: conntrack: set icmpv6 redirects as RELATED
[ Upstream commit 7d7cfb48d8 ]

icmp conntrack will set icmp redirects as RELATED, but icmpv6 will not
do this.

For icmpv6, only icmp errors (code <= 128) are examined for RELATED state.
ICMPV6 Redirects are part of neighbour discovery mechanism, those are
handled by marking a selected subset (e.g.  neighbour solicitations) as
UNTRACKED, but not REDIRECT -- they will thus be flagged as INVALID.

Add minimal support for REDIRECTs.  No parsing of neighbour options is
added for simplicity, so this will only check that we have the embeeded
original header (ND_OPT_REDIRECT_HDR), and then attempt to do a flow
lookup for this tuple.

Also extend the existing test case to cover redirects.

Ido Schimmel 2537b637ea ipv4: Fix incorrect route flushing when source address is deleted
[ Upstream commit f96a3d7455 ]

Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is
deleted from a different VRF.

Fix by taking the table ID into account when looking for a matching FIB
info. This is already done for FIB info structures backed by a nexthop
object in fib_find_info_nh().

Add test cases that fail before the fix:

 # ./fib_tests.sh -t ipv4_del_addr

 IPv4 delete address route tests
     Regular FIB info
     TEST: Route removed from VRF when source address deleted            [ OK ]

     TEST: Route in VRF is not removed by address delete                 [ OK ]

     TEST: Route removed from VRF when source address deleted            [FAIL]

     TEST: Route removed in default VRF when source address deleted      [ OK ]
     TEST: Route in VRF is not removed by address delete                 [FAIL]

 Tests passed:   6
 Tests failed:   2

And pass after:

Ido Schimmel 899e148171 ipv4: Fix route deletion when nexthop info is not specified
[ Upstream commit d5082d386e ]

When the kernel receives a route deletion request from user space it
tries to delete a route that matches the route attributes specified in
the request.

If only prefix information is specified in the request, the kernel
should delete the first matching FIB alias regardless of its associated
FIB info. However, an error is currently returned when the FIB info is
backed by a nexthop object:

 # ip nexthop add id 1 via 192.0.2.2 dev dummy10
 # ip route add 198.51.100.0/24 nhid 1
 # ip route del 198.51.100.0/24
 RTNETLINK answers: No such process

Fix by matching on such a FIB info when legacy nexthop attributes are
not specified in the request. An earlier check already covers the case
where a nexthop ID is specified in the request.

Add tests that cover these flows. Before the fix:

 # ./fib_nexthops.sh -t ipv4_fcnal
 ...
 TEST: Delete route when not specifying nexthop attributes           [FAIL]

 Tests passed:  11
 Tests failed:   1

After the fix:

 # ./fib_nexthops.sh -t ipv4_fcnal
 ...
 TEST: Delete route when not specifying nexthop attributes           [ OK ]

 Tests passed:  12
 Tests failed:   0

[ Upstream commit 392baa339c ]

Add a test which causes a WARNING on kernels which treat a
nexthop route like a normal route when comparing for deletion and a
device is specified. That is, a route is found but we hit a warning while
matching it. The warning is from fib_info_nh() in include/net/nexthop.h
because we run it on a fib_info with nexthop object. The call chain is:
 inet_rtm_delroute -> fib_table_delete -> fib_nh_match (called with a
nexthop fib_info and also with fc_oif set thus calling fib_info_nh on
the fib_info and triggering the warning).

Repro steps:
 $ ip nexthop add id 12 via 172.16.1.3 dev veth1
 $ ip route add 172.16.101.1/32 nhid 12
 $ ip route delete 172.16.101.1/32 dev veth1

A new feature is added where kprobes (and other probes) do not need to

come from what is being attached.

That is:

  # echo 'p:foo/ vfs_read' > kprobe_events

Will no longer error, but instead create an event:

  # cat kprobe_events
 p:foo/p_vfs_read_0 vfs_read

This should not be tested as an error case anymore. Remove it from the
selftest as now this feature "breaks" the selftest as it no longer fails

The selftests, when built with newer versions of clang, is found
to have over optimized guests' ucall() function, and eliminating
the stores for uc.cmd (perhaps due to no immediate readers). This
resulted in the userspace side always reading a value of '0', and
causing multiple test failures.

As a result, prevent the compiler from optimizing the stores in
ucall() with WRITE_ONCE().
