Char/Misc and other Driver changes for 6.8-rc1
Here is the big set of char/misc and other driver subsystem changes for 6.8-rc1. Lots of stuff in here, but first off, you will get a merge conflict in drivers/android/binder_alloc.c when merging this tree due to changing coming in through the -mm tree. The resolution of the merge issue can be found here: https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au or in a simpler patch form in that thread: https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com If there are issues with the merge of this file, please let me know. Other than lots of binder driver changes (as you can see by the merge conflicts) included in here are: - lots of iio driver updates and additions - spmi driver updates - eeprom driver updates - firmware driver updates - ocxl driver updates - mhi driver updates - w1 driver updates - nvmem driver updates - coresight driver updates - platform driver remove callback api changes - tags.sh script updates - bus_type constant marking cleanups - lots of other small driver updates All of these have been in linux-next for a while with no reported issues (other than the binder merge conflict.)

scripts/decode_stacktrace.sh: optionally use LLVM utilities
GNU's addr2line can have problems parsing a vmlinux built with LLVM, particularly when LTO was used. In order to decode the traces correctly this patch adds the ability to switch to LLVM's utilities readelf and addr2line. The same approach is followed by Will in [1]. Before: $ scripts/decode_stacktrace.sh vmlinux < kernel.log [17716.240635] Call trace: [17716.240646] skb_cow_data (??:?) [17716.240654] esp6_input (ld-temp.o:?) [17716.240666] xfrm_input (ld-temp.o:?) [17716.240674] xfrm6_rcv (??:?) [...] After: $ LLVM=1 scripts/decode_stacktrace.sh vmlinux < kernel.log [17716.240635] Call trace: [17716.240646] skb_cow_data (include/linux/skbuff.h:2172 net/core/skbuff.c:4503) [17716.240654] esp6_input (net/ipv6/esp6.c:977) [17716.240666] xfrm_input (net/xfrm/xfrm_input.c:659) [17716.240674] xfrm6_rcv (net/ipv6/xfrm6_input.c:172) [...] Note that one could set CROSS_COMPILE=llvm- instead to hack around this issue. However, doing so can break the decodecode routine as it will force the selection of other LLVM utilities down the line e.g. llvm-as.

Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
warning that was added in 6.2.
- Some reworking of the Documentation/process front page to, hopefully,
make it more useful.
- Various kernel-doc tweaks to, for example, make it deal properly with
__counted_by annotations.
- We have also restored a warning for documentation of nonexistent
structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained
effort by Randy, Vegard, and myself has addressed almost all of those,
bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.
- Various improvements to the HTML rendered docs, including automatic links
to Git revisions and a nice new pulldown to make translations easy to
access.
- Speaking of translations, more of those for Spanish and Chinese.
...plus the usual stream of documentation updates and typo fixes.

Rust changes for v6.8
Another routine one in terms of features. In terms of lines, this time
the 'alloc' version upgrade is less prominent, given that it was fairly
small (and we did not have two upgrades).
Toolchain and infrastructure:
- Upgrade to Rust 1.74.1.
The patch release includes a fix for an ICE that the Apple AGX GPU
driver was hitting.
- Support 'srctree'-relative links in Rust code documentation.
- Automate part of the manual constants handling (i.e. the ones not
recognised by 'bindgen').
- Suppress searching builtin sysroot to avoid confusion with installed
sysroots, needed for the to-be-merged arm64 support which uses
a builtin target.
- Ignore '__preserve_most' functions for 'bindgen'.
- Reduce header inclusion bloat in exports.
'kernel' crate:
- Implement 'Debug' for 'CString'.
- Make 'CondVar::wait()' an uninterruptible wait.
'macros' crate:
- Update 'paste!' to accept string literals.
- Improve '#[vtable]' documentation.
Documentation:
- Add testing section (KUnit and 'rusttest' target).
- Remove 'CC=clang' mentions.
- Clarify that 'rustup override' applies to build directory.

Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances.
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host.
- Add support for ethtool symmetric-xor RSS hash.
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform.
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute.
- Convert older drivers to platform remove callback returning void.
- Add support for PHY package MMD read/write.

usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter
- Support for VLAN tag in XDP hints
- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)
Misc:
- Support for parellel TC self-tests execution
- Increase MPTCP self-tests coverage
- Updated the bridge documentation, including several so-far
undocumented features
- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs
- Add TCP-AO self-tests
- Add kunit tests for both cfg80211 and mac80211
- Autogenerate Netlink families documentation from YAML spec
- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs
- A bunch of additional module descriptions fixes
- Catch incorrect freeing of pages belonging to a page pool
Driver API:
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host
- Add support for ethtool symmetric-xor RSS hash
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute

asm-generic cleanups for 6.8
A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems.

kernel-doc: handle a void function without producing a warning
Currently a void function can produce a warning:
main.c:469: warning: contents before sections
This one is from arch/x86/kernel/cpu/sgx/main.c (which is not included
in any produced kernel documentation output).
Handle this by setting $in_doc_sect to 1 whenever any recognized
document section name is processed.

scripts/get_abi: fix source path leak
The code currently leaks the absolute path of the ABI files into the rendered documentation. There exists code to prevent this, but it is not effective when an absolute path is passed, which it is when $srctree is used. I consider this to be a minimal, stop-gap fix; a better fix would strip off the actual prefix instead of hacking it off with a regex.

get_maintainer: remove stray punctuation when cleaning file emails
When parsing emails from .yaml files in particular, stray punctuation
such as a leading '-' can end up in the name. For example, consider a
common YAML section such as:
maintainers:
- devicetree@vger.kernel.org
This would previously be processed by get_maintainer.pl as:
- <devicetree@vger.kernel.org>
Make the logic in clean_file_emails more robust by deleting any
sub-names which consist of common single punctuation marks before
proceeding to the best-effort name extraction logic. The output is then
correct:
devicetree@vger.kernel.org
Some additional comments are added to the function to make things
clearer to future readers.

get_maintainer: correctly parse UTF-8 encoded names in files
While the script correctly extracts UTF-8 encoded names from the
MAINTAINERS file, the regular expressions damage my name when parsing
from .yaml files. Fix this by replacing the Latin-1-compatible regular
expressions with the unicode property matcher \p{L}, which matches on
any letter according to the Unicode General Category of letters.
The proposed solution only works if the script uses proper string
encoding from the outset, so instruct Perl to unconditionally open all
files with UTF-8 encoding. This should be safe, as the entire source
tree is either UTF-8 or ASCII encoded anyway. See [1] for a detailed
analysis.
Furthermore, to prevent the \w expression from matching non-ASCII when
checking for whether a name should be escaped with quotes, add the /a
flag to the regular expression. The escaping logic was duplicated in
two places, so it has been factored out into its own function.
The original issue was also identified on the tools mailing list [2].
This should solve the observed side effects there as well.

scripts/decode_stacktrace.sh: strip unexpected CR from lines
When the kernel log is acquired over a serial cable it is not uncommon for the log to contain carriage return characters, in addition to the expected line feeds. When this output is feed into decode_stacktrace.sh, handle_line() fails to strip the trailing ']' off the module name, which results in find_module() not being able to find the referred to kernel module. This is reported to the user as: WARNING! Modules path isn't set, but is needed to parse this symbol The solution is to reconfigure the serial port, or to strip the carriage returns from the log, but this isn't obvious from the error reported by the script. Instead, make decode_stacktrace.sh more user friendly by stripping the trailing carriage return.

scripts/checkstack.pl: change min_stack to 512 by default
According to Documentation/process/submit-checklist.rst, checkstack does not point out problems explicitly, but any one function that uses more than 512 bytes on the stack is a candidate for change, hence it is better to omit any stack frame sizes smaller than 512 bytes, just change min_stack to 512 by default.

scripts/checkstack.pl: match all stack sizes for some archs
For some unknown reason the regular expression for checkstack only matches
three digit numbers starting with the number "3", or any higher number.
Which means that it skips any stack sizes smaller than 304 bytes. This
makes the checkstack script a bit less useful than it could be.
Change the script to match any number. To be filtered out stack sizes can
be configured with the min_stack variable, which omits any stack frame
sizes smaller than 100 bytes by default.
This is similar with commit

gen_compile_commands.py: fix path resolve with symlinks in it
When a path contains relative symbolic links, os.path.abspath() might
not follow the symlinks and instead return the absolute path with just
the relative paths resolved, resulting in an incorrect path.
1. Say "drivers/hdf/" has some symlinks:
# ls -l drivers/hdf/
total 364
drwxrwxr-x 2 ... 4096 ... evdev
lrwxrwxrwx 1 ... 44 ... framework -> ../../../../../../drivers/hdf_core/framework
-rw-rw-r-- 1 ... 359010 ... hdf_macro_test.h
lrwxrwxrwx 1 ... 55 ... inner_api -> ../../../../../../drivers/hdf_core/interfaces/inner_api
lrwxrwxrwx 1 ... 53 ... khdf -> ../../../../../../drivers/hdf_core/adapter/khdf/linux
-rw-r--r-- 1 ... 74 ... Makefile
drwxrwxr-x 3 ... 4096 ... wifi
2. One .cmd file records that:
# head -1 ./framework/core/manager/src/.devmgr_service.o.cmd
cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \
/path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c
3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct:
# ./scripts/clang-tools/gen_compile_commands.py
INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \
/path/to/src/framework/core/manager/src/devmgr_service.c not found
Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly.
# cat compile_commands.json
...
{
"command": ...
"directory": ...
"file": "/path/to/bla/drivers/hdf_core/framework/core/manager/src/devmgr_service.c"
},
...
Also fix it in parse_arguments().

Makefile.extrawarn: turn on missing-prototypes globally
Over the years we went from > 1000 of warnings to under 100 earlier this year, and I sent patches to address all the ones that I saw with compile testing randcom configs on arm64, arm and x86 kernels. This is a really useful warning, as it catches real bugs when there are mismatched prototypes. In particular with kernel control flow integrity enabled, those are no longer allowed. I have done extensive testing to ensure that there are no new build errors or warnings on any configuration of x86, arm and arm64 builds. I also made sure that at least both the normal defconfig and an allmodconfig build is clean for arc, csky, loongarch, m68k, microblaze, openrisc, parisc, powerpc, riscv, s390, and xtensa, with the respective maintainers doing most of the patches. At this point, there are five architectures with a number of known regressions: alpha, nios2, mips, sh and sparc. In the previous version of this patch, I had turned off the missing prototype warnings for the 15 architectures that still had issues, but since there are only five left, I think we can leave the rest to the maintainers (Cc'd here) as well.

* Use fwnode_property_string_array_count() inside
fwnode_property_match_string() instead of open coding the same.
checkpatch.pl
* Add exclusion of __aligned() from a warning reducing false positives
on IIO drivers (and hopefully beyond)
IIO Features
------------
core
* New light channel modifiers for UVA and UVB.
* Add IIO_CHAN_INFO_TROUGH as counterpart to IIO_CHAN_INFO_PEAK so that
we can support device that keep running track of the lowest value they
have seen in similar fashion to the existing peak tracking.
adi,adis library
* Use spi cs inactive delay even when a burst reading is performed.
As it's now used every time, can centralize the handling in the SPI
setup code in the driver.

pins are hard wired to config mode in which case position and config
must be read from appropriate config registers.
* Support reset GPIO if present.
adi,ad5791

if default delays are not quite enough for a specific board.
bosch,bmp280
* Enable multiple chip IDs per family of devices.

Cleanup
-------
Minor white space, typos and tidy up not explicitly called out.
Core
* Check that the available_scan_masks array passed to the IIO core
by a driver is sensible by ensuring the entries are ordered so the
minimum number of channels is enabled in the earlier entries (as they
will be selected if sufficient for the requested channels).
* Document that the available_scan_masks infrastructure doesn't currently
handle masks that don't fit in a long int.
* Improve intensity documentation to reflect that there is no expectation
of sensible units (it's dependent on a frequency sensitivity curve)
Various
* Use new device_property_match_property_string() to replace open coded
versions of the same thing.
* Fix a few MAINTAINERS filenames.
* i2c_get_match_data() and spi_get_device_match_data() pushed into
more drivers reducing boilerplate handling.
* Some unnecessary headers removed.
* ACPI_PTR() removals. It's rarely worth using this.
adi,ad7091r (early part of a series adding device support - useful in
their own right)
* Pass iio_dev directly an event handler rather than relying
on broken use of dev_get_drvdata() as drvdata is never set in this driver.
* Make sure alert is turned on.
adi,ad9467 (general driver fixing up as precursor to iio-backend proposal
which is under review for 6.9)
* Fix reset gpio handling to match expected polarity.

pascals.
invensense,mpu6050
* Don't eat a potentially useful return value from regmap_bulk_write()
invensense,icm42600
* Use max macro to improve code readability and save a few lines.
liteon,ltrf216a
* Improve prevision of light intensity.

kernel-doc: Align quick help and the code
The update to the quick help mentions -Wshort-description, but
code never supported for that. Align that with the code by allowing
both: -Wshort-description and -Wshort-desc.

docs: ignore __counted_by attribute in structure definitions
kernel-doc appeared to ignore __counted_by, but appearances can be deceiving; it caused member names to not be recognized, which manifested as a number of spurious "Excess struct member" warnings. Filter that attribute out and reduce the warning onslaught slightly. Signed-off-by: Jonathan Corbet <corbet@lwn.net> |

scripts: checkpatch: Add __aligned to the list of attribute notes
Checkpatch presumes attributes marked with __aligned(alignment) are part of a function declaration and throws a warning stating that those compiler attributes should have an identifier name which is not correct. Add __aligned compiler attributes to the list of attribute notes so they don't cause warnings anymore.

scripts/kernel-doc: restore warning for Excess struct/union
The warning for Excess struct or union member description was
removed when the $nested parameter of check_sections() was removed.
This causes some kernel-doc notation warnings to be missed.
Recently the kernel test robot somehow reported an Excess member. The
code in kernel-doc has not issued that warning since kernel v4.16, so I
don't know how the robot did it. (See the Link for the report.)
drivers/net/wireless/intel/iwlwifi/fw/dbg.c:86: warning: Excess struct/union/enum/typedef member 'trans_len' description in 'iwl_fw_dump_ptrs'
I patched that warning away even though I could not reproduce the
warning from kernel-doc. The warning should be issued for extraneous
struct member or union member description, so restore it.

rust: Suppress searching builtin sysroot
By default, if Rust is passed `--target=foo` rather than a target.json file, it will infer a default sysroot if that component is installed. As the proposed aarch64 support [1] uses `aarch64-unknown-none` rather than a target.json file, this is needed [2] to prevent rustc from being confused between the custom kernel sysroot and the pre-installed one. [ Miguel: Applied Boqun's extra case (for `rusttest`) and reworded to add links to the arm64 patch series discussion. In addition, fixed the `rustdoc` target too (which requires a conditional since `cmd_rustdoc` is also used for host crates like `macros`). ] Signed-off-by: Matthew Maurer <mmaurer@google.com> Tested-by: Boqun Feng <boqun.feng@gmail.com> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Link: https://lore.kernel.org/rust-for-linux/20231020155056.3495121-1-Jamie.Cunliffe@arm.com/ [1] Link: https://lore.kernel.org/rust-for-linux/CAGSQo01pOixiPXkW867h4vPUaAjtKtHGKhkV-rpifJvKxAf4Ww@mail.gmail.com/ [2] Link: https://lore.kernel.org/r/20231031201752.1189213-1-mmaurer@google.com Signed-off-by: Miguel Ojeda <ojeda@kernel.org> |

sign-file: Fix incorrect return values check
There are some wrong return values check in sign-file when call OpenSSL
API. The ERR() check cond is wrong because of the program only check the
return value is < 0 which ignored the return val is 0. For example:
1. CMS_final() return 1 for success or 0 for failure.
2. i2d_CMS_bio_stream() returns 1 for success or 0 for failure.
3. i2d_TYPEbio() return 1 for success and 0 for failure.
4. BIO_free() return 1 for success and 0 for failure.

checkpatch: add ethtool_sprintf rules
Add some warnings for using ethtool_sprintf() where a simple ethtool_puts() would suffice. The two cases are: 1) Use ethtool_sprintf() with just two arguments: | ethtool_sprintf(&data, driver[i].name); or 2) Use ethtool_sprintf() with a standalone "%s" fmt string: | ethtool_sprintf(&data, "%s", driver[i].name); The former may cause -Wformat-security warnings while the latter is just not preferred. Both are safely in the category of warnings, not errors. Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Signed-off-by: David S.
