math between map_value pointer and 4294967294 is not allowed
Before this series we did not trip the "math between map_value pointer..."
error because check_reg_sane_offset is never called in
adjust_ptr_min_max_vals(). Instead we have a register state that looks
like this at line 11*,
11: R0_w=map_value(id=0,off=0,ks=8,vs=8,
smin_value=0,smax_value=0,
umin_value=0,umax_value=0,
var_off=(0x0; 0x0))
R1_w=invP(id=0,
smin_value=0,smax_value=4294967295,
umin_value=0,umax_value=4294967295,
var_off=(0xfffffffe; 0x0))
R10=fp(id=0,off=0,
smin_value=0,smax_value=0,
umin_value=0,umax_value=0,
var_off=(0x0; 0x0)) fp-8_w=mmmmmmmm
11: (0f) r0 += r1
In R1 'smin_val != smax_val' yet we have a tnum_const as seen
by 'var_off(0xfffffffe; 0x0))' with a 0x0 mask. So we hit this check
in adjust_ptr_min_max_vals()
if ((known && (smin_val != smax_val || umin_val != umax_val)) ||
smin_val > smax_val || umin_val > umax_val) {
/* Taint dst register if offset had invalid bounds derived from
* e.g. dead branches.
*/
__mark_reg_unknown(env, dst_reg);
return 0;
}
So we don't throw an error here and instead only throw an error
later in the verification when the memory access is made.
The root cause in verifier without alu32 bounds tracking is having
'umin_value = 0' and 'umax_value = U64_MAX' from BPF_SUB which we set
when 'umin_value < umax_val' here,
if (dst_reg->umin_value < umax_val) {
/* Overflow possible, we know nothing */
dst_reg->umin_value = 0;
dst_reg->umax_value = U64_MAX;
} else { ...}
Later in adjust_calar_min_max_vals we previously did a
coerce_reg_to_size() which will clamp the U64_MAX to U32_MAX by
truncating to 32bits. But either way without a call to update_reg_bounds
the less precise bounds tracking will fall out of the alu op
verification.
After latest changes we now exit adjust_scalar_min_max_vals with the
more precise umin value, due to zero extension propogating bounds from
alu32 bounds into alu64 bounds and then calling update_reg_bounds.
This then causes the verifier to trigger an earlier error and we get
the error in the output above.
This patch updates tests to reflect new error message.
* I have a local patch to print entire verifier state regardless if we
believe it is a constant so we can get a full picture of the state.
Usually if tnum_is_const() then bounds are also smin=smax, etc. but
this is not always true and is a bit subtle. Being able to see these
states helps understand dataflow imo. Let me know if we want something
similar upstream.

Rework kunit_tool in order to allow .kunitconfig files to better enforce
that disabled items in .kunitconfig are disabled in the generated
.config.
Previously, kunit_tool simply enforced that any line present in
.kunitconfig was also present in .config, but this could cause problems
if a config option was disabled in .kunitconfig, but not listed in .config
due to (for example) having disabled dependencies.
To fix this, re-work the parser to track config names and values, and
require values to match unless they are explicitly disabled with the
"CONFIG_x is not set" comment (or by setting its value to 'n'). Those
"disabled" values will pass validation if omitted from the .config, but
not if they have a different value.

The test case tm-signal-context-force-tm expects a segfault to happen
on returning from signal handler, and then does a setcontext() to run
the test again. However, the test doesn't always segfault, causing the
test to run a single time.
This patch fixes the test by putting it within a loop and jumping, via
setcontext, just prior to the loop in case it segfaults. This way we
get the desired behavior (run the test COUNT_MAX times) regardless if
it segfaults or not. This also reduces the use of setcontext for
control flow logic, keeping it only in the segfault handler.
Also, since 'count' is changed within the signal handler, it is
declared as volatile to prevent any compiler optimization getting
confused with asynchronous changes.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) A new selftest for nf_queue, from Florian Westphal. This test
covers two recent fixes: 07f8e4d0fddb ("tcp: also NULL skb->dev
when copy was needed") and b738a185beaa ("tcp: ensure skb->dev is
NULL before leaving TCP stack").
2) The fwd action breaks with ifb. For safety in next extensions,
make sure the fwd action only runs from ingress until it is extended
to be used from a different hook.
3) The pipapo set type now reports EEXIST in case of subrange overlaps.
Update the rbtree set to validate range overlaps, so far this
validation is only done only from userspace. From Stefano Brivio.

Add a test case to check nf queue infrastructure.
Could be extended in the future to also cover serialization of
conntrack, uid and secctx attributes in nfqueue.
For now, this checks that 'queue bypass' works, that a queue rule with
no bypass option blocks traffic and that userspace receives the expected
number of packets.
For this we add two queues and hook all of
prerouting/input/forward/output/postrouting.
Packets get queued twice with a dummy base chain in between:
This passes with current nf tree, but reverting
commit 946c0d8e6ed4 ("netfilter: nf_queue: fix reinject verdict handling")
makes this trip (it processes 30 instead of expected 20 packets).
v2: update config file with queue and other options missing/needed for
other tests.
v3: also test with tcp, this reveals problem with commit
28f8bfd1ac94 ("netfilter: Support iif matches in POSTROUTING"), due to
skb->dev pointing at another skb in the retransmit rbtree (skb->dev
aliases to rbnode child).

libc
Many systems build/test up-to-date kernels with older libcs, and
an older glibc (2.17) lacks the definition of SOL_DCCP in
/usr/include/bits/socket.h (it was added in the 4.6 timeframe).
Adding the definition to the test program avoids a compilation
failure that gets in the way of building tools/testing/selftests/net.
The test itself will work once the definition is added; either
skipping due to DCCP not being configured in the kernel under test
or passing, so there are no other more up-to-date glibc dependencies
here it seems beyond that missing definition.

Implemented the functionality to run all KUnit tests through kunit_tool
by specifying an --alltests flag, which builds UML with allyesconfig
enabled, and consequently runs every KUnit test. A new function was
added to kunit_kernel: make_allyesconfig.
Firstly, if --alltests is specified, kunit.py triggers build_um_kernel
which call make_allyesconfig. This function calls the make command,
disables the broken configs that would otherwise prevent UML from
building, then starts the kernel with all possible configurations
enabled. All stdout and stderr is sent to test.log and read from there
then fed through kunit_parser to parse the tests to the user. Also added
a signal_handler in case kunit is interrupted while running.
Tested: Run under different conditions such as testing with
--raw_output, testing program interrupt then immediately running kunit
again without --alltests and making sure to clean the console.

Previously, kunit_parser did not properly handle kunit TAP output that
- had any prefixes (generated from different configs e.g.
CONFIG_PRINTK_TIME)
- had unrelated kernel output mixed in the middle of
it, which has shown up when testing with allyesconfig
To remove prefixes, the parser looks for the first line that includes
TAP output, "TAP version 14". It then determines the length of the
string before this sequence, and strips that number of characters off
the beginning of the following lines until the last KUnit output line is
reached.
These fixes have been tested with additional tests in the
KUnitParseTest and their associated logs have also been added.

test_vdso would try to call a NULL pointer if the vDSO was missing.
vdso_restorer_32 hit a genuine failure: trying to use the
kernel-provided signal restorer doesn't work if the vDSO is missing.
Skip the test if the vDSO is missing, since the test adds no particular
value in that case.
