This patch adds a selftest simulating a GRE sender and receiver using

This patch allows to remove TUNNEL_KEY from the tunnel flags bitmap
when using bpf_skb_set_tunnel_key by providing a BPF_F_NO_TUNNEL_KEY
flag. On egress, the resulting tunnel header will not contain a tunnel
key if the protocol and implementation supports it.

At the moment bpf_tunnel_key wants a user to specify a numeric tunnel
key. This will wrap the inner packet into a tunnel header with the key
bit and value set accordingly. This is problematic when using a tunnel
protocol that supports optional tunnel keys and a receiving tunnel
device that is not expecting packets with the key bit set. The receiver
won't decapsulate and drop the packet.

RFC 2890 and RFC 2784 GRE tunnels are examples where this flag is
useful. It allows for generating packets, that can be decapsulated by
a GRE tunnel device not operating in collect metadata mode or not
expecting the key bit set.

Both bpf_trace_printk and bpf_trace_vprintk helpers use static buffer guarded
with trace_printk_lock spin lock.

The spin lock contention causes issues with bpf programs attached to
contention_begin tracepoint [1][2].

Andrii suggested we could get rid of the contention by using trylock, but we
could actually get rid of the spinlock completely by using percpu buffers the
same way as for bin_args in bpf_bprintf_prepare function.

Adding new return 'buf' argument to struct bpf_bprintf_data and making
bpf_bprintf_prepare to return also the buffer for printk helpers.

Currently we always cleanup/decrement bpf_bprintf_nest_level variable
in bpf_bprintf_cleanup if it's > 0.

There's possible scenario where this could cause a problem, when
bpf_bprintf_prepare does not get bin_args buffer (because num_args is 0)
and following bpf_bprintf_cleanup call decrements bpf_bprintf_nest_level
variable, like:

  in task context:
    bpf_bprintf_prepare(num_args != 0) increments 'bpf_bprintf_nest_level = 1'
    -> first irq :
       bpf_bprintf_prepare(num_args == 0)
       bpf_bprintf_cleanup decrements 'bpf_bprintf_nest_level = 0'
    -> second irq:
       bpf_bprintf_prepare(num_args != 0) bpf_bprintf_nest_level = 1
       gets same buffer as task context above

Fix bug in btf_dump's logic of determining if a given struct type is
packed or not. The notion of "natural alignment" is not needed and is
even harmful in this case, so drop it altogether. The biggest difference
in btf_is_struct_packed() compared to its original implementation is
that we don't really use btf__align_of() to determine overall alignment
of a struct type (because it could be 1 for both packed and non-packed
struct, depending on specifci field definitions), and just use field's
actual alignment to calculate whether any field is requiring packing or
struct's size overall necessitates packing.

Add two simple test cases that demonstrate the difference this change
would make.

Turns out that btf_dump API doesn't handle a bunch of tricky corner
cases, as reported by Per, and further discovered using his testing
Python script ([0]).

This patch revamps btf_dump's padding logic significantly, making it
more correct and also avoiding unnecessary explicit padding, where
compiler would pad naturally. This overall topic turned out to be very
tricky and subtle, there are lots of subtle corner cases. The comments
in the code tries to give some clues, but comments themselves are
supposed to be paired with good understanding of C alignment and padding
rules. Plus some experimentation to figure out subtle things like
whether `long :0;` means that struct is now forced to be long-aligned
(no, it's not, turns out).

Anyways, Per's script, while not completely correct in some known
situations, doesn't show any obvious cases where this logic breaks, so
this is a nice improvement over the previous state of this logic.

Some selftests had to be adjusted to accommodate better use of natural
alignment rules, eliminating some unnecessary padding, or changing it to
`type: 0;` alignment markers.

Note also that for when we are in between bitfields, we emit explicit
bit size, while otherwise we use `: 0`, this feels much more natural in
practice.

Next patch will add few more test cases, found through randomized Per's
script.

btf__align_of() is supposed to be return alignment requirement of
a requested BTF type. For STRUCT/UNION it doesn't always return correct
value, because it calculates alignment only based on field types. But
for packed structs this is not enough, we need to also check field
offsets and struct size. If field offset isn't aligned according to
field type's natural alignment, then struct must be packed. Similarly,
if struct size is not a multiple of struct's natural alignment, then
struct must be packed as well.

This patch fixes this issue precisely by additionally checking these
conditions.

Turns out C allows to force enum to be 1-byte or 8-byte explicitly using
mode(byte) or mode(word), respecticely. Linux sources are using this in
some cases. This is imporant to handle correctly, as enum size
determines corresponding fields in a struct that use that enum type. And
if enum size is incorrect, this will lead to invalid struct layout. So
add mode(byte) and mode(word) attribute support to btf_dump APIs.

This is a small improvement in libbpf_strerror. When libbpf_strerror
is used to obtain the system error description, if the length of the
buf is insufficient, libbpf_sterror returns ERANGE and sets errno to
ERANGE.

However, this processing is not performed when the error code
customized by libbpf is obtained. Make some minor improvements here,
return -ERANGE and set errno to ERANGE when buf is not enough for
custom description.

Pull EFI updates from Ard Biesheuvel:
 "Another fairly sizable pull request, by EFI subsystem standards.

  Most of the work was done by me, some of it in collaboration with the
  distro and bootloader folks (GRUB, systemd-boot), where the main focus
  has been on removing pointless per-arch differences in the way EFI
  boots a Linux kernel.

   - Refactor the zboot code so that it incorporates all the EFI stub
     logic, rather than calling the decompressed kernel as a EFI app.

   - Add support for initrd= command line option to x86 mixed mode.

   - Allow initrd= to be used with arbitrary EFI accessible file systems
     instead of just the one the kernel itself was loaded from.

   - Move some x86-only handling and manipulation of the EFI memory map
     into arch/x86, as it is not used anywhere else.

   - More flexible handling of any random seeds provided by the boot
     environment (i.e., systemd-boot) so that it becomes available much
     earlier during the boot.

   - Allow improved arch-agnostic EFI support in loaders, by setting a
     uniform baseline of supported features, and adding a generic magic
     number to the DOS/PE header. This should allow loaders such as GRUB
     or systemd-boot to reduce the amount of arch-specific handling
     substantially.

   - (arm64) Run EFI runtime services from a dedicated stack, and use it
     to recover from synchronous exceptions that might occur in the
     firmware code.

   - (arm64) Ensure that we don't allocate memory outside of the 48-bit
     addressable physical range.

   - Make EFI pstore record size configurable

   - Add support for decoding CXL specific CPER records"

 "Tux gets for xmas an improvement to the average lookup performance of
  kallsyms_lookup_name() by 715x thanks to the work by Zhen Lei, which
  upgraded our old implementation from being O(n) to O(log(n)), while
  also retaining the old implementation support on /proc/kallsyms.

  The only penalty was increasing the memory footprint by 3 *
  kallsyms_num_syms. Folks who want to improve this further now also
  have a dedicated selftest facility through KALLSYMS_SELFTEST.

  Stephen Boyd added zstd in-kernel decompression support, but the only
  users of this would be folks using the load-pin LSM because otherwise
  we do module decompression in userspace.

  The only other thing with mentioning is a minor boot time optimization
  by Rasmus Villemoes which deferes param_sysfs_init() to late init. The
  rest is cleanups and minor fixes"

Pull clk driver updates from Stephen Boyd:
 "A pile of clk driver updates with a small tracepoint patch to the clk
  core this time around.

  The core framework is effectively unchanged, with the majority of the
  diff going to the Qualcomm clk driver directory because they added two
  3k line files that are almost all clk data (Abel Vesa from Linaro
  tried to shrink the number of lines down, but it doesn't seem to be
  possible without sacrificing readability).

  The second big driver this time around is the Rockchip rk3588 clk and
  reset unit, at _only_ 2.5k lines.

  Ignoring the big clk drivers from the familiar SoC vendors, there's
  just a bunch of little clk driver updates and fixes throughout here.

  It's the usual set of clk data fixups to describe proper parents, or
  add frequencies to frequency tables, or plug memory leaks when
  function calls fail. Also, some drivers are converted to use modern
  clk_hw APIs, which is always nice to see. And data is deduplicated,
  leading to a smaller kernel Image.

  Overall this batch has a larger collection of cleanups than it
  typically does. Maybe that means there are less new SoCs right now
  that need supporting, and the focus has shifted to quality and
  reliability. I can dream.

  New Drivers:
   - Frequency hopping controller hardware on MediaTek MT8186
   - Global clock controller for Qualcomm SM8550
   - Display clock controller for Qualcomm SC8280XP
   - RPMh clock controller for Qualcomm QDU1000 and QRU1000 SoCs

Pull devicetree updates from Rob Herring:
 "DT Bindings:

   - Various LED binding conversions and clean-ups. Convert the
     ir-spi-led, pwm-ir-tx, and gpio-ir-tx LED bindings to schemas.
     Consistently reference LED common.yaml or multi-led schemas and
     disallow undefined properties.

   - Convert IDT 89HPESx, pwm-clock, st,stmipid02, Xilinx PCIe hosts,
     and fsl,imx-fb bindings to schema

   - Add ata-generic, Broadcom u-boot environment, and dynamic MTD
     sub-partitions bindings.

   - Make all SPI based displays reference spi-peripheral-props.yaml

   - Fix some schema property regex's which should be fixed strings or
     were missing start/end anchors

   - Remove 'status' in examples, again...

  DT Core:

   - Fix a possible NULL dereference in overlay functions

   - Fix kexec reading 32-bit "linux,initrd-{start,end}" values (which
     never worked)

   - Add of_address_count() helper to count number of 'reg' entries

   - Support .dtso extension for DT overlay source files. Rename staging
     and unittest overlay files.

   - Update dtc to upstream v1.6.1-63-g55778a03df61"
