To accommodate for legacy devices, we rely on the last state of a
transition to be valid:
for example when we test PEN_IS_OUT_OF_RANGE to PEN_IS_IN_CONTACT,
any "normal" device that reports an InRange bit would insert a
PEN_IS_IN_RANGE state between the 2.
This is of course valid, but this solution prevents to detect false
releases emitted by some firmware:
when pressing an "eraser mode" button, they might send an extra
PEN_IS_OUT_OF_RANGE that we may want to filter.
So define 2 sets of transitions: one that is the ideal behavior, and
one that is OK, it won't break user space, but we have serious doubts
if we are doing the right thing. And depending on the test, either
ask only for valid transitions, or tolerate weird ones.

We get more descriptive in what we are doing, and also get more
information of what is actually being tested. Instead of having a non
exhaustive button changes that are semi-randomly done, we can describe
all the states we want to test.

Turns out that there are transitions that are unlikely to happen:
for example, having both the tip switch and a button being changed
at the same time (in the same report) would require either a very talented
and precise user or a very bad hardware with a very low sampling rate.
So instead of manually building the button test by hand and forgetting
about some cases, let's reuse the state machine and transitions we have.
This patch only adds the states and the valid transitions. The actual
tests will be replaced later.

Those transitions have nothing to do with `Pen`, so migrate them to
`PenState`.
The hidden agenda is to remove `Pen` and integrate it into `PenDigitizer`
so that we can tweak the events in each state to emulate firmware bugs.

Commit 05f1edac8009 ("selftests/mm: run all tests from run_vmtests.sh")
fixed the inconsistency caused by tests being defined as TEST_GEN_PROGS.
This issue was leading to tests not being executed via run_vmtests.sh and
furthermore some tests running twice due to the kselftests wrapper also
executing them.
Fix the definition of two tests (soft-dirty and pagemap_ioctl) that are
still incorrectly defined.

To stay consistent with the naming pattern used for similar cases in BPF
UAPI (__MAX_BPF_ATTACH_TYPE, etc), rename MAX_BPF_LINK_TYPE into
__MAX_BPF_LINK_TYPE.
Also similar to MAX_BPF_ATTACH_TYPE and MAX_BPF_REG, add:
#define MAX_BPF_LINK_TYPE __MAX_BPF_LINK_TYPE
Not all __MAX_xxx enums have such #define, so I'm not sure if we should
add it or not, but I figured I'll start with a completely backwards
compatible way, and we can drop that, if necessary.
Also adjust a selftest that used MAX_BPF_LINK_TYPE enum.

Adding test that tries to trigger the BUG_IN during early map update
in prog_array_map_poke_run function.
The idea is to share prog array map between thread that constantly
updates it and another one loading a program that uses that prog
array.
Eventually we will hit a place where the program is ok to be updated
(poke->tailcall_target_stable check) but the address is still not
registered in kallsyms, so the bpf_arch_text_poke returns -EINVAL
and cause imbalance for the next tail call update check, which will
fail with -EBUSY in bpf_arch_text_poke as described in previous fix.

Add a selftest that attempts to conceptually replicate intended BPF
token use cases inside user namespaced container.
Child process is forked. It is then put into its own userns and mountns.
Child creates BPF FS context object. This ensures child userns is
captured as the owning userns for this instance of BPF FS. Given setting
delegation mount options is privileged operation, we ensure that child
cannot set them.
This context is passed back to privileged parent process through Unix
socket, where parent sets up delegation options, creates, and mounts it
as a detached mount. This mount FD is passed back to the child to be
used for BPF token creation, which allows otherwise privileged BPF
operations to succeed inside userns.
We validate that all of token-enabled privileged commands (BPF_BTF_LOAD,
BPF_MAP_CREATE, and BPF_PROG_LOAD) work as intended. They should only
succeed inside the userns if a) BPF token is provided with proper
allowed sets of commands and types; and b) namespaces CAP_BPF and other
privileges are set. Lacking a) or b) should lead to -EPERM failures.
Based on suggested workflow by Christian Brauner ([0]).

Add a new selftests that validates precision tracking for stack access
instruction, using both r10-based and non-r10-based accesses. For
non-r10 ones we also make sure to have non-zero var_off to validate that

Use instruction (jump) history to record instructions that performed
register spill/fill to/from stack, regardless if this was done through
read-only r10 register, or any other register after copying r10 into it
*and* potentially adjusting offset.
To make this work reliably, we push extra per-instruction flags into
instruction history, encoding stack slot index (spi) and stack frame
number in extra 10 bit flags we take away from prev_idx in instruction
history. We don't touch idx field for maximum performance, as it's
checked most frequently during backtracking.
This change removes basically the last remaining practical limitation of
precision backtracking logic in BPF verifier. It fixes known
deficiencies, but also opens up new opportunities to reduce number of
verified states, explored in the subsequent patches.
There are only three differences in selftests' BPF object files
according to veristat, all in the positive direction (less states).
File Program Insns (A) Insns (B) Insns (DIFF) States (A) States (B) States (DIFF)
-------------------------------------- ------------- --------- --------- ------------- ---------- ---------- -------------
test_cls_redirect_dynptr.bpf.linked3.o cls_redirect 2987 2864 -123 (-4.12%) 240 231 -9 (-3.75%)
xdp_synproxy_kern.bpf.linked3.o syncookie_tc 82848 82661 -187 (-0.23%) 5107 5073 -34 (-0.67%)
xdp_synproxy_kern.bpf.linked3.o syncookie_xdp 85116 84964 -152 (-0.18%) 5162 5130 -32 (-0.62%)
Note, I avoided renaming jmp_history to more generic insn_hist to
minimize number of lines changed and potential merge conflicts between
bpf and bpf-next trees.
Notice also cur_hist_entry pointer reset to NULL at the beginning of
instruction verification loop. This pointer avoids the problem of
relying on last jump history entry's insn_idx to determine whether we
already have entry for current instruction or not. It can happen that we
added jump history entry because current instruction is_jmp_point(), but
also we need to add instruction flags for stack access. In this case, we
don't want to entries, so we need to reuse last added entry, if it is
present.
Relying on insn_idx comparison has the same ambiguity problem as the one
that was fixed recently in [0], so we avoid that.

xdp_metadata test is flaky sometimes:
verify_xsk_metadata:FAIL:rx_hash_type unexpected rx_hash_type: actual 8 != expected 0
Where 8 means XDP_RSS_TYPE_L4_ANY and is exported from veth driver only when
'skb->l4_hash' condition is met. This makes me think that the program is
triggering again for some other packet.
Let's have a filter, similar to xdp_hw_metadata, where we trigger XDP kfuncs
only for UDP packets destined to port 8080.

There was some confusion amongst Meta sched_ext folks regarding whether
stashing bpf_rb_root - the tree itself, rather than a single node - was
supported. This patch adds a small test which demonstrates this
functionality: a local kptr with rb_root is created, a node is created
and added to the tree, then the tree is kptr_xchg'd into a mapval.

When do arping, the interface need to be specified. Or we will
get error: Interface "lo" is not ARPable. And the test failed.

Add a lib.sh for net selftests. This file can be used to define commonly
used variables and functions. Some commonly used functions can be moved
from forwarding/lib.sh to this lib file. e.g. busywait().
Add function setup_ns() for user to create unique namespaces with given
prefix name.

Syscall program is running with rcu_read_lock_trace being held, so if
bpf_map_update_elem() or bpf_map_delete_elem() invokes
synchronize_rcu_tasks_trace() when operating on an outer map, there will
be dead-lock, so add a test to guarantee that it is dead-lock free.

Add test cases to test the race between the destroy of inner map due to
map-in-map update and the access of inner map in bpf program. The
following 4 combinations are added:
(1) array map in map array + bpf program
(2) array map in map array + sleepable bpf program
(3) array map in map htab + bpf program
(4) array map in map htab + sleepable bpf program
Before applying the fixes, when running `./test_prog -a map_in_map`, the
following error was reported:

Commit 458ba8189cb4 ("cxl: Add cxl_decoders_committed() helper") missed the

replace the open coding.
