[ Upstream commit 59ed76fe2f981bccde37bdddb465f260a96a2404 ]
Kernel function urandom_read is replaced with urandom_read_iter.
Therefore, kprobe on urandom_read is not working any more:
[root@eth50-1 bpf]# ./test_progs -n 161
test_stacktrace_build_id:PASS:skel_open_and_load 0 nsec

libbpf: prog 'oncpu': failed to auto-attach: -2
test_stacktrace_build_id:FAIL:attach_tp err -2
161 stacktrace_build_id:FAIL
Fix this by replacing urandom_read with urandom_read_iter in the test.

commit 8ba0005ff418ec356e176b26eaa04a6ac755d05b upstream.
The original behavior was to check if the full set of requested accesses
was allowed by at least a rule of every relevant layer. This didn't
take into account requests for multiple accesses and same-layer rules
allowing the union of these accesses in a complementary way. As a
result, multiple accesses requested on a file hierarchy matching rules
that, together, allowed these accesses, but without a unique rule
allowing all of them, was illegitimately denied. This case should be
rare in practice and it can only be triggered by the path_rename or
file_open hook implementations.
For instance, if, for the same layer, a rule allows execution
beneath /a/b and another rule allows read beneath /a, requesting access
to read and execute at the same time for /a/b should be allowed for this
layer.
This was an inconsistency because the union of same-layer rule accesses
was already allowed if requested once at a time anyway.
This fix changes the way allowed accesses are gathered over a path walk.
To take into account all these rule accesses, we store in a matrix all
layer granting the set of requested accesses, according to the handled
accesses. To avoid heap allocation, we use an array on the stack which
is 2*13 bytes. A following commit bringing the LANDLOCK_ACCESS_FS_REFER
access right will increase this size to reach 112 bytes (2*14*4) in case
of link or rename actions.
Add a new layout1.layer_rule_unions test to check that accesses from
different rules pertaining to the same layer are ORed in a file
hierarchy. Also test that it is not the case for rules from different
layers.

commit 75c542d6c6cc48720376862d5496d51509160dfd upstream.
The maximum number of nested Landlock domains is currently 64. Because
of the following fix and to help reduce the stack size, let's reduce it
to 16. This seems large enough for a lot of use cases (e.g. sandboxed
init service, spawning a sandboxed SSH service, in nested sandboxed
containers). Reducing the number of nested domains may also help to
discover misuse of Landlock (e.g. creating a domain per rule).
Add and use a dedicated layer_mask_t typedef to fit with the number of
layers. This might be useful when changing it and to keep it consistent
with the maximum number of layers.

commit ead165fa1042247b033afad7be4be9b815d04ade upstream.
Nathan reported objtool failing with the following messages:
warning: objtool: no non-local symbols !?
warning: objtool: gelf_update_symshndx: invalid section index
The problem is due to commit 4abff6d48dbc ("objtool: Fix code relocs
vs weak symbols") failing to consider the case where an object would
have no non-local symbols.
The problem that commit tries to address is adding a STB_LOCAL symbol
to the symbol table in light of the ELF spec's requirement that:
In each symbol table, all symbols with STB_LOCAL binding preced the
weak and global symbols. As ``Sections'' above describes, a symbol
table section's sh_info section header member holds the symbol table
index for the first non-local symbol.
The approach taken is to find this first non-local symbol, move that
to the end and then re-use the freed spot to insert a new local symbol
and increment sh_info.
Except it never considered the case of object files without global
symbols and got a whole bunch of details wrong -- so many in fact that
it is a wonder it ever worked :/
Specifically:
- It failed to re-hash the symbol on the new index, so a subsequent
find_symbol_by_index() would not find it at the new location and a
query for the old location would now return a non-deterministic
choice between the old and new symbol.
- It failed to appreciate that the GElf wrappers are not a valid disk
format (it works because GElf is basically Elf64 and we only
support x86_64 atm.)
- It failed to fully appreciate how horrible the libelf API really is
and got the gelf_update_symshndx() call pretty much completely
wrong; with the direct consequence that if inserting a second
STB_LOCAL symbol would require moving the same STB_GLOBAL symbol
again it would completely come unstuck.
Write a new elf_update_symbol() function that wraps all the magic
required to update or create a new symbol at a given index.
Specifically, gelf_update_sym*() require an @ndx argument that is
relative to the @data argument; this means you have to manually
iterate the section data descriptor list and update @ndx.

In the origin code, when "ExtSel" is 1, the eventcode will change to

its "ExtSel" is "1", its eventcode will change from 0x1E to 0x20001E,
but in fact the eventcode should <=0x1FF, so this will cause the parse
fail:

event syntax error: '.._RxL_CREDITS_CONSUMED_VN0.DRS'
\___ value too big for format, maximum is 511
On the perf kernel side, the kernel assumes the valid bits are continuous.
It will adjust the 0x100 (bit 8 for perf tool) to bit 21 in HW.
DEFINE_UNCORE_FORMAT_ATTR(event_ext, event, "config:0-7,21");
So the perf tool follows the kernel side and just set bit8 other than bit21.

The "bti" selftests are built with -nostdlib, which apparently
automatically creates a statically linked binary, which is what we want
and need for BTI (to avoid interactions with the dynamic linker).
However this is not true when building a PIE binary, which some
toolchains (Ubuntu) configure as the default.
When compiling btitest with such a toolchain, it will create a
dynamically linked binary, which will probably fail some tests, as the
dynamic linker might not support BTI:
===================
TAP version 13
1..18
not ok 1 nohint_func/call_using_br_x0
not ok 2 nohint_func/call_using_br_x16
not ok 3 nohint_func/call_using_blr
....
===================
To make sure we create static binaries, add an explicit -static on the
linker command line. This forces static linking even if the toolchain
defaults to PIE builds, and fixes btitest runs on BTI enabled machines.

-config is stripped to find the Python runtime.

[ Upstream commit e299bcd4d16ff86f46c48df1062c8aae0eca1ed8 ]
Since commit 6521f89170 ("namei: prepare for idmapped mounts")
vfs_link's prototype was changed, the kprobe definition in
profiler selftest in turn wasn't updated. The result is that all
argument after the first are now stored in different registers. This
means that self-test has been broken ever since. Fix it by updating the
kprobe definition accordingly.

[ Upstream commit e71b7f1f44d3d88c677769c85ef0171caf9fc89f ]
The 'ping' utility is able to manage two kind of sockets (raw or icmp),
depending on the sysctl ping_group_range. By default, ping_group_range is
set to '1 0', which forces ping to use an ip raw socket.
Let's replay the ping tests by allowing 'ping' to use the ip icmp socket.
After the previous patch, ipv4 tests results are the same with both kinds
of socket. For ipv6, there are a lot a new failures (the previous patch
fixes only two cases).

[ Upstream commit 01b28e4a58152e8906eeb5f1b55a0c404c48c7c8 ]
The X86 specific arch__intr_reg_mask() is to check whether the kernel
and hardware can collect XMM registers. But it doesn't work on some
hybrid platform.
Without the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15
The config of the test event doesn't contain the PMU information. The
kernel may fail to initialize it on the correct hybrid PMU and return
the wrong non-supported information.
Add the PMU information into the config for the hybrid platform. The
same register set is supported among different hybrid PMUs. Checking
the first available one is good enough.
With the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15 XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 XMM8 XMM9

[ Upstream commit 0ae065a5d265bc5ada13e350015458e0c5e5c351 ]
Avi Kivity reported a problem where the __weak
btf__load_from_kernel_by_id() in tools/perf/util/bpf-event.c was being
used and it called btf__get_from_id() in tools/lib/bpf/btf.c that in
turn called back to btf__load_from_kernel_by_id(), resulting in an
endless loop.
Fix this by adding a feature test to check if
btf__load_from_kernel_by_id() is available when building perf with
LIBBPF_DYNAMIC=1, and if not then provide the fallback to the old
btf__get_from_id(), that doesn't call back to btf__load_from_kernel_by_id()
since at that time it didn't exist at all.
Tested on Fedora 35 where we have libbpf-devel 0.4.0 with LIBBPF_DYNAMIC
where we don't have btf__load_from_kernel_by_id() and thus its feature
test fail, not defining HAVE_LIBBPF_BTF__LOAD_FROM_KERNEL_BY_ID:

[ Upstream commit 41c240099fe09377b6b9f8272e45d2267c843d3e ]
The tools/testing/selftests/vm/Makefile uses the variable TARGETS
internally to generate a list of platform-specific binary build targets
suffixed with _{32,64}. When building the selftests using its own
Makefile directly, such as via the following command run in a kernel tree:
One receives an error such as the following:
make: Entering directory '/root/linux/tools/testing/selftests'
make --no-builtin-rules ARCH=x86 -C ../../.. headers_install
make[1]: Entering directory '/root/linux'
INSTALL ./usr/include
make[1]: Leaving directory '/root/linux'
make[1]: Entering directory '/root/linux/tools/testing/selftests/vm'
make[1]: *** No rule to make target 'vm.c', needed by '/root/linux/tools/testing/selftests/vm/vm_64'. Stop.
make[1]: Leaving directory '/root/linux/tools/testing/selftests/vm'
make: *** [Makefile:175: all] Error 2
make: Leaving directory '/root/linux/tools/testing/selftests'
The TARGETS variable passed to tools/testing/selftests/Makefile collides
with the TARGETS used in tools/testing/selftests/vm/Makefile, so rename
the latter to VMTARGETS, eliminating the collision with no functional
