commit eda0cf1202acf1ef47f93d8f92d4839213431424 upstream.
Add a specific test for the reload issue fixed with
commit 23c54263efd7cb ("netfilter: nft_set_pipapo: allocate pcpu scratch maps on clone").
Add to set, then flush set content + restore without other add/remove in
the transaction.
On kernels before the fix, this test case fails:

commit 87c01d57fa23de82fff593a7d070933d08755801 upstream.
hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.
To make hmm_range_fault() more closely match get_user_pages() remove
this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte(). Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.
Also add a test to hmm selftest to verify functionality.

commit 4624f199327a704dd1069aca1c3cadb8f2a28c6f upstream.
Because of commit bf794bf52a80c627 ("powerpc/kprobes: Fix kallsyms
lookup across powerpc ABIv1 and ABIv2"), in ppc64 ABIv1, our perf
command eliminates the need to use the prefix "." at the symbol name.
But when the command "perf probe -a schedule" is executed on ppc64
ABIv1, it obtains two symbol address information through /proc/kallsyms,
for example:
cat /proc/kallsyms | grep -w schedule
c000000000657020 T .schedule
c000000000d4fdb8 D schedule
The symbol "D schedule" is not a function symbol, and perf will print:
"p:probe/schedule _text+13958584"Failed to write event: Invalid argument
Therefore, when searching symbols from map and adding probe point for
them, a symbol type check is added. If the type of symbol is not a
function, skip it.

commit 3606c0e1a1050d397ad759a62607e419fd8b0ccb upstream.
A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.

commit de0244ae40ae91145faaf164a4252347607c3711 upstream.
Ammar Faizi reported that our exit code handling is wrong. We truncate
it to the lowest 8 bits but the syscall itself is expected to take a
regular 32-bit signed integer, not an unsigned char. It's the kernel
that later truncates it to the lowest 8 bits. The difference is visible
in strace, where the program below used to show exit(255) instead of
exit(-1):
int main(void)
{
return -1;
}
This patch applies the fix to all archs. x86_64, i386, arm64, armv7 and
mips were all tested and confirmed to work fine now. Risc-v was not
tested but the change is trivial and exactly the same as for other archs.

After re-checking in the spec and comparing stack offsets with glibc,
The last pushed argument must be 16-byte aligned (i.e. aligned before the
call) so that in the callee esp+4 is multiple of 16, so the principle is
the 32-bit equivalent to what Ammar fixed for x86_64. It's possible that
32-bit code using SSE2 or MMX could have been affected. In addition the
frame pointer ought to be zero at the deepest level.

commit 937ed91c712273131de6d2a02caafd3ee84e0c72 upstream.
Before this patch, the `_start` function looks like this:
```
0000000000001170 <_start>:
1170: pop %rdi
1171: mov %rsp,%rsi
1174: lea 0x8(%rsi,%rdi,8),%rdx
1179: and $0xfffffffffffffff0,%rsp
117d: sub $0x8,%rsp
1181: call 1000 <main>
1186: movzbq %al,%rdi
118a: mov $0x3c,%rax
1191: syscall
1193: hlt
1194: data16 cs nopw 0x0(%rax,%rax,1)
119f: nop
```
Note the "and" to %rsp with $-16, it makes the %rsp be 16-byte aligned,
but then there is a "sub" with $0x8 which makes the %rsp no longer
16-byte aligned, then it calls main. That's the bug!
What actually the x86-64 System V ABI mandates is that right before the
"call", the %rsp must be 16-byte aligned, not after the "call". So the
"sub" with $0x8 here breaks the alignment. Remove it.
An example where this rule matters is when the callee needs to align
its stack at 16-byte for aligned move instruction, like `movdqa` and
`movaps`. If the callee can't align its stack properly, it will result
in segmentation fault.
x86-64 System V ABI also mandates the deepest stack frame should be
zero. Just to be safe, let's zero the %rbp on startup as the content
of %rbp may be unspecified when the program starts. Now it looks like
this:
```
0000000000001170 <_start>:
1170: pop %rdi
1171: mov %rsp,%rsi
1174: lea 0x8(%rsi,%rdi,8),%rdx
1179: xor %ebp,%ebp # zero the %rbp
117b: and $0xfffffffffffffff0,%rsp # align the %rsp
117f: call 1000 <main>
1184: movzbq %al,%rdi
1188: mov $0x3c,%rax
118f: syscall
1191: hlt
1192: data16 cs nopw 0x0(%rax,%rax,1)
119d: nopl (%rax)

test_syncookie:FAIL:Unexpected syncookie states gen_cookie:80326634 recv_cookie:0
bpf prog error at line 97
"error at line 97" means the bpf prog cannot find the listening socket
when the final ack is received. It then skipped processing
the syncookie in the final ack which then led to "recv_cookie:0".
The problem is the userspace program did not do accept() and went
ahead to close(listen_fd) before the kernel (and the bpf prog) had
a chance to process the final ack.
The fix is to add accept() call so that the userspace will wait for
the kernel to finish processing the final ack first before close()-ing
everything.

An overflow (OVF packet) is treated as an error because it represents a
loss of trace data, but there is no loss of synchronization, so the packet
state should be INTEL_PT_STATE_IN_SYNC not INTEL_PT_STATE_ERR_RESYNC.
To support that, some additional variables must be reset, and the FUP
packet that may follow OVF is treated as an FUP event.

commit b560b21f71eb4ef9dfc7c8ec1d0e4d7f9aa54b51 upstream.
This commit adds BPF verifier selftests that cover all corner cases by
packet boundary checks. Specifically, 8-byte packet reads are tested at
the beginning of data and at the beginning of data_meta, using all kinds
of boundary checks (all comparison operators: <, >, <=, >=; both
permutations of operands: data + length compared to end, end compared to
data + length). For each case there are three tests:
1. Length is just enough for an 8-byte read. Length is either 7 or 8,
depending on the comparison.
2. Length is increased by 1 - should still pass the verifier. These
cases are useful, because they failed before commit 2fa7d94afc1a
("bpf: Fix the off-by-two error in range markings").
3. Length is decreased by 1 - should be rejected by the verifier.
Some existing tests are just renamed to avoid duplication.

commit f6071e5e3961eeb5300bd0901c9e128598730ae3 upstream.
Currently rp_filter tests in fib_tests.sh:fib_rp_filter_test() are
failing. ping sockets are bound to dummy1 using the "-I" option
(SO_BINDTODEVICE), but socket lookup is failing when receiving ping
replies, since the routing table thinks they belong to dummy0.
For example, suppose ping is using a SOCK_RAW socket for ICMP messages.
When receiving ping replies, in __raw_v4_lookup(), sk->sk_bound_dev_if
is 3 (dummy1), but dif (skb_rtable(skb)->rt_iif) says 2 (dummy0), so the
raw_sk_bound_dev_eq() check fails. Similar things happen in
ping_lookup() for SOCK_DGRAM sockets.
These tests used to pass due to a bug [1] in iputils, where "ping -I"
actually did not bind ICMP message sockets to device. The bug has been
fixed by iputils commit f455fee41c07 ("ping: also bind the ICMP socket
to the specific device") in 2016, which is why our rp_filter tests
started to fail. See [2] .
Fixing the tests while keeping everything in one netns turns out to be
nontrivial. Rework the tests and build the following topology:
┌─────────────────────────────┐ ┌─────────────────────────────┐
│ network namespace 1 (ns1) │ │ network namespace 2 (ns2) │
│ │ │ │
│ ┌────┐ ┌─────┐ │ │ ┌─────┐ ┌────┐ │
│ │ lo │<───>│veth1│<────────┼────┼─>│veth2│<──────────>│ lo │ │
│ └────┘ ├─────┴──────┐ │ │ ├─────┴──────┐ └────┘ │
│ │192.0.2.1/24│ │ │ │192.0.2.1/24│ │
│ └────────────┘ │ │ └────────────┘ │
└─────────────────────────────┘ └─────────────────────────────┘
Consider sending an ICMP_ECHO packet A in ns2. Both source and
destination IP addresses are 192.0.2.1, and we use strict mode rp_filter
in both ns1 and ns2:
1. A is routed to lo since its destination IP address is one of ns2's
local addresses (veth2);
2. A is redirected from lo's egress to veth2's egress using mirred;
3. A arrives at veth1's ingress in ns1;
4. A is redirected from veth1's ingress to lo's ingress, again, using
mirred;
5. In __fib_validate_source(), fib_info_nh_uses_dev() returns false,
since A was received on lo, but reverse path lookup says veth1;
6. However A is not dropped since we have relaxed this check for lo in
commit 66f8209547cc ("fib: relax source validation check for loopback
packets");
Making sure A is not dropped here in this corner case is the whole point
of having this test.
7. As A reaches the ICMP layer, an ICMP_ECHOREPLY packet, B, is
generated;
8. Similarly, B is redirected from lo's egress to veth1's egress (in
ns1), then redirected once again from veth2's ingress to lo's
ingress (in ns2), using mirred.
Also test "ping 127.0.0.1" from ns2. It does not trigger the relaxed
check in __fib_validate_source(), but just to make sure the topology
works with loopback addresses.

commit 3d1d57debee2d342a47615707588b96658fabb85 upstream.
Since 66dfdff03d196e51 ("perf tools: Add Python 3 support") we don't use
the tools/build/feature/test-libpython-version.c version in any Makefile
feature check:
$ find tools/ -type f | xargs grep feature-libpython-version
$
The only place where this was used was removed in 66dfdff03d196e51:
- ifneq ($(feature-libpython-version), 1)
- $(warning Python 3 is not yet supported; please set)
- $(warning PYTHON and/or PYTHON_CONFIG appropriately.)
- $(warning If you also have Python 2 installed, then)
- $(warning try something like:)
- $(warning $(and ,))
- $(warning $(and ,) make PYTHON=python2)
- $(warning $(and ,))
- $(warning Otherwise, disable Python support entirely:)
- $(warning $(and ,))
- $(warning $(and ,) make NO_LIBPYTHON=1)
- $(warning $(and ,))
- $(error $(and ,))
- else
- LDFLAGS += $(PYTHON_EMBED_LDFLAGS)
- EXTLIBS += $(PYTHON_EMBED_LIBADD)
- LANG_BINDINGS += $(obj-perf)python/perf.so
- $(call detected,CONFIG_LIBPYTHON)
- endif
And nowadays we either build with PYTHON=python3 or just install the
python3 devel packages and perf will build against it.
But the leftover feature-libpython-version check made the fast path
feature detection to break in all cases except when python2 devel files
were installed:
$ rpm -qa | grep python.*devel
python3-devel-3.9.7-1.fc34.x86_64
$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ;
$ make -C tools/perf O=/tmp/build/perf install-bin

$
As python3 is the norm these days, fix this by just removing the unused
feature-libpython-version feature check, making the test-all fast path
to work with the common case.
With this:
$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ;

commit 2fa7d94afc1afbb4d702760c058dc2d7ed30f226 upstream.
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.

commit d43b75fbc23f0ac1ef9c14a5a166d3ccb761a451 upstream.
After the below patch, the conntrack attached to skb is set to "notrack" in
the context of vrf device, for locally generated packets.
But this is true only when the default qdisc is set to the vrf device. When
changing the qdisc, notrack is not set anymore.
In fact, there is a shortcut in the vrf driver, when the default qdisc is
set, see commit dcdd43c41e60 ("net: vrf: performance improvements for
IPv4") for more details.
This patch ensures that the behavior is always the same, whatever the qdisc
is.
To demonstrate the difference, a new test is added in conntrack_vrf.sh.

commit 20ae1d6aa159eb91a9bf09ff92ccaa94dbea92c2 upstream.
Each peer's endpoint contains a dst_cache entry that takes a reference
to another netdev. When the containing namespace exits, we take down the
socket and prevent future sockets from being created (by setting
creating_net to NULL), which removes that potential reference on the
netns. However, it doesn't release references to the netns that a netdev
cached in dst_cache might be taking, so the netns still might fail to
exit. Since the socket is gimped anyway, we can simply clear all the
dst_caches (by way of clearing the endpoint src), which will release all
references.
However, the current dst_cache_reset function only releases those
references lazily. But it turns out that all of our usages of
wg_socket_clear_peer_endpoint_src are called from contexts that are not
exactly high-speed or bottle-necked. For example, when there's
connection difficulty, or when userspace is reconfiguring the interface.
And in particular for this patch, when the netns is exiting. So for
those cases, it makes more sense to call dst_release immediately. For
that, we add a small helper function to dst_cache.
This patch also adds a test to netns.sh from Hangbin Liu to ensure this
doesn't regress.
