[ Upstream commit 76a4c8b82938bc5020b67663db41f451684bf327 ]
Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional
digits, therefore leading zeros are meaningful.
This patch changes the format strings to "%lld.%09u" in order to add
leading zeros to the nanosecond value.

Partially backport v6.3 commit 11f75a01448f ("selftests/memfd: add tests
for MFD_NOEXEC_SEAL MFD_EXEC") to fix an unknown type name build error.
In some systems, the __u64 typedef is not present due to differences in
system headers, causing compilation errors like this one:
fuse_test.c:64:8: error: unknown type name '__u64'
64 | static __u64 mfd_assert_get_seals(int fd)
This header includes the __u64 typedef which increases the likelihood
of successful compilation on a wider variety of systems.

[ Upstream commit 05107edc910135d27fe557267dc45be9630bf3dd ]
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).

commit 4e7d2a8f0b52abf23b1dc13b3d88bc0923383cd5 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.

commit e8bf9b98d40dbdf4e39362e3b85a70c61da68cb7 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.

grub2 has submenus where to use grub-reboot, it requires:
grub-reboot X>Y
where X is the main index and Y is the submenu. Thus if you have:
menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ...
[...]
}
submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ...
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ...
[...]
}
menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ...
[...]
}
And wanted to boot to the "Linux test" kernel, you need to run:
# grub-reboot 1>2
As 1 is the second top menu (the submenu) and 2 is the third of the sub
menu entries.
Have the grub.cfg parsing for grub2 handle such cases.

This issue was first noticed when I was testing different kernels on
Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a
kernel entry was added successfully and the index of that kernel entry was
retrieved correctly, ktest still wouldn't reboot the system into
user-specified kernel.
The bug was spotted in subroutine reboot_to where the if-statement never
checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be
set for the next boot.
Add a check for "grub2bls" so that $grub_reboot $grub_number can
be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to
the correct kernel.

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.

The first commit cited below attempts to fix the off-by-one error that
appeared in some comparisons with an open range. Due to this error,
arithmetically equivalent pieces of code could get different verdicts
from the verifier, for example (pseudocode):
// 1. Passes the verifier:
if (data + 8 > data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
// 2. Rejected by the verifier (should still pass):
if (data + 7 >= data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
The attempted fix, however, shifts the range by one in a wrong
direction, so the bug not only remains, but also such piece of code
starts failing in the verifier:
// 3. Rejected by the verifier, but the check is stricter than in #1.
if (data + 8 >= data_end)
return early
read *(u64 *)data, i.e. [data; data+7]
The change performed by that fix converted an off-by-one bug into
off-by-two. The second commit cited below added the BPF selftests
written to ensure than code chunks like #3 are rejected, however,
they should be accepted.
This commit fixes the off-by-two error by adjusting new_range in the
right direction and fixes the tests by changing the range into the
one that should actually fail.

The first host interface has by default no interest in receiving packets
MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc
filter and this might confuse the selftest.
Enable promiscuous mode such that the filter properly counts received
packets.

[ Upstream commit b8e629b05f5d23f9649c901bef09fab8b0c2e4b9 ]
As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

commit 3122257c02afd9f199a8fc84ae981e1fc4958532 upstream.
In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.
When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.
Fix this by taking br1 down and bringing it back up when it is fully
configured.
With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

CPU set. This cpu set is used further in pthread_attr_setaffinity_np
and by pthread_create in the code. But in current code, allocated
cpu set is not freed.
Fix this issue by adding CPU_FREE in the "shutdown" function which
is called in most of the error/exit path for the cleanup. There are
few error paths which exit without using shutdown. Add a common goto
error path with CPU_FREE for these cases.

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

need to cleanup zram twice if fails.
