Remove Intel compiler support
include/linux/compiler-intel.h had no update in the past 3 years.
We often forget about the third C compiler to build the kernel.

kasan: treat meminstrinsic as builtins in uninstrumented files
Where the compiler instruments meminstrinsics by generating calls to
__asan/__hwasan_ prefixed functions, let the compiler consider
memintrinsics as builtin again.
To do so, never override memset/memmove/memcpy if the compiler does the
correct instrumentation - even on !GENERIC_ENTRY architectures.
[elver@google.com: powerpc: don't rename memintrinsics if compiler adds prefixes]

kasan: emit different calls for instrumentable memintrinsics
Clang 15 provides an option to prefix memcpy/memset/memmove calls with
__asan_/__hwasan_ in instrumented functions:
https://reviews.llvm.org/D122724
GCC will add support in future:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108777
Use it to regain KASAN instrumentation of memcpy/memset/memmove on
architectures that require noinstr to be really free from instrumented
mem*() functions (all GENERIC_ENTRY architectures).

kbuild: deb-pkg: improve the usability of source package
Improve the source package support in case the dpkg-buildpackage is directly used to build binary packages. For cross-compiling, you can set CROSS_COMPILE via the environment variable, but it is better to set it automatically - set it to ${DEB_HOST_GNU_TYPE}- if we are cross-compiling but not from the top Makefile. The generated source package may be carried to a different build environment, which may have a different compiler installed. Run olddefconfig first to set new CONFIG options to their default values without prompting. Take KERNELRELEASE and KBUILD_BUILD_VERSION from the version field of debian/changelog in case it is updated afterwards. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

kbuild: deb-pkg: fix binary-arch and clean in debian/rules
The clean target needs ARCH=${ARCH} to clean up the tree for the correct architecture. 'make (bin)deb-pkg' skips cleaning, but the preclean hook may be executed if dpkg-buildpackage is directly used. The binary-arch target does not need KERNELRELEASE because it is not updated during the installation. KBUILD_BUILD_VERSION is not needed either because binary-arch does not build vmlinux.

kbuild: make perf-tar*-src-pkg work without relying on git
Currently, perf-tar*-src-pkg only uses 'git archive', but it is better to make it work without relying on git. The file, HEAD, which saves the commit hash, will be included in the tarball only when the source tree is managed by git. The git tree is more precisely checked; it has been copied from scripts/setlocalversion. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

kbuild: deb-pkg: switch over to source format 3.0 (quilt)
Change the source format from "1.0" to "3.0 (quilt)" because it works more cleanly. All files except .config and debian/ go into the orig tarball. Add a single patch, debian/patches/config, and delete the ugly extend-diff-ignore patterns. The debian tarball will be compressed into *.debian.tar.xz by default. If you like to use a different compression mode, you can pass the command line option, DPKG_FLAGS=-Zgzip, for example. The orig tarball only supports gzip for now. The combination of gzip and xz is somewhat clumsy, but it is not a practical problem. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu> |

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall.

modules-6.3-rc1
Nothing exciting at all for modules for v6.3. The biggest change is
just the change of INSTALL_MOD_DIR from "extra" to "updates" which
I found lingered for ages for no good reason while testing the CXL
mock driver [0]. The CXL mock driver has no kconfig integration and requires
building an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash. All this crap can obviously be fixed by integrating kconfig
semantics into such test module, however that's not desirable by
the maintainer, and so sensible defaults must be used to ensure a
default "make modules_install" will suffice for most distros which
do not have a file like /etc/depmod.d/dist.conf with something like
`search updates extra built-in`. Since most distros rely on kmod and
since its inception the "updates" directory is always in the search
path it makes more sense to use that than the "extra" which only
*some* RH based systems rely on. All this stuff has been on linux-next
for a while.
For v6.4 I already have queued some initial work by Song Liu which gets
us slowly going to a place where we *may* see a generic allocator for
huge pages for module text to avoid direct map fragmentation *and*
reduce iTLB pressure. That work is in its initial stages, no allocator
work is done yet. This is all just prep work. Fortunately Thomas Gleixner
has helped convince Song that modules *need* to be *requirement* if we
are going to see any special allocator touch x86. So who knows... maybe
around v6.5 we'll start seeing some *real* performance numbers of the
effect of using huge pages for something other than eBPF toys.
For v6.4 also, you may start seeing patches from Nick Alcock on different
trees and modules-next which aims at extending kallsyms *eventually* to provide
clearer address to symbol lookups. The claim is that this is a *great* *feature*
tracing tools are dying to have so they can for instance disambiguate symbols as
coming from modules or from other parts of the kernel. I'm still waiting to see
proper too usage of such stuff, but *how* we lay this out is still being ironed
out. Part of the initial work I've been pushing for is to help upkeep our
modules build optimizations, so being mindful about the work by Masahiro Yamada

Networking changes for 6.3.
Core ---- - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols --------- - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF --- - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter --------- - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt. races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API ---------- - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

scripts/decodecode: Add support for RISC-V
RISC-V has some GNU disassembly quirks, e.g. it requires '-D' to properly disassemble .2byte directives similar to Arm [1]. Further, GNU objdump groups RISC-V instruction by 2 or 4 byte chunks, instead doing byte-for-byte. Add the required switches, and translate from short/word to bytes when ARCH is "riscv". An example how to invoke decodecode for RISC-V: $ echo 'Code: bf45 f793 1007 f7d9 50ef 37af d541 b7d9 7097 00c8 (80e7) 6140' | AFLAGS="-march=rv64imac_zicbom_zihintpause" \ ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- ./scripts/decodecode Code: bf45 f793 1007 f7d9 50ef 37af d541 b7d9 7097 00c8 (80e7) 6140 All code ======== 0: bf45 c.j 0xffffffffffffffb0 2: 1007f793 andi a5,a5,256 6: f7d9 c.bnez a5,0xffffffffffffff94 8: 37af50ef jal ra,0xf5382 c: d541 c.beqz a0,0xffffffffffffff94 e: b7d9 c.j 0xffffffffffffffd4 10: 00c87097 auipc ra,0xc87 14:* 614080e7 jalr ra,1556(ra) # 0xc87624 <-- trapping instruction Code starting with the faulting instruction =========================================== 0: 614080e7 jalr ra,1556(ra) [1] https://sourceware.org/bugzilla/show_bug.cgi?id=10263 Signed-off-by: Björn Töpel <bjorn@rivosinc.com> Tested-by: Alexandre Ghiti <alexghiti@rivosinc.com> Link: https://lore.kernel.org/r/20230119074738.708301-3-bjorn@kernel.org Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

tracing: Always use canonical ftrace path
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing Many comments and Kconfig help messages in the tracing code still refer to this older debugfs path, so let's update them to avoid confusion.

kbuild: add a tool to list files ignored by git
In short, the motivation of this commit is to build a source package without cleaning the source tree. The deb-pkg and (src)rpm-pkg targets first run 'make clean' before creating a source tarball. Otherwise build artifacts such as *.o, *.a, etc. would be included in the tarball. Yet, the tarball ends up containing several garbage files since 'make clean' does not clean everything. Cleaning the tree every time is annoying since it makes the incremental build impossible. It is desirable to create a source tarball without cleaning the tree. In fact, there are some ways to achieve this. The easiest solution is 'git archive'. 'make perf-tar*-src-pkg' uses it, but I do not like it because it works only when the source tree is managed by git, and all files you want in the tarball must be committed in advance. I want to make it work without relying on git. We can do this. Files that are ignored by git are generated files, so should be excluded from the source tarball. We can list them out by parsing the .gitignore files. Of course, .gitignore does not cover all the cases, but it works well enough. tar(1) claims to support it: --exclude-vcs-ignores Exclude files that match patterns read from VCS-specific ignore files. Supported files are: .cvsignore, .gitignore, .bzrignore, and .hgignore. The best scenario would be to use 'tar --exclude-vcs-ignores', but this option does not work. --exclude-vcs-ignore does not understand any of the negation (!), preceding slash, following slash, etc.. So, this option is just useless. Hence, I wrote this gitignore parser. The previous version [1], written in Python, was so slow. This version is implemented in C, so it works much faster. I imported the code from git (commit: 23c56f7bd5f1), so we get the same result. This tool traverses the source tree, parsing all .gitignore files, and prints file paths that are ignored by git. The output is similar to 'git ls-files --ignored --directory --others --exclude-per-directory=.gitignore', except [1] Not sorted [2] No trailing slash for directories [2] is intentional because tar's --exclude-from option cannot handle trailing slashes. [How to test this tool] $ git clean -dfx $ make -s -j$(nproc) defconfig all # or allmodconifg or whatever $ git archive -o ../linux1.tar --prefix=./ HEAD $ tar tf ../linux1.tar | LANG=C sort > ../file-list1 # files emitted by 'git archive' $ make scripts_package HOSTCC scripts/list-gitignored $ scripts/list-gitignored --prefix=./ -o ../exclude-list $ tar cf ../linux2.tar --exclude-from=../exclude-list . $ tar tf ../linux2.tar | LANG=C sort > ../file-list2 # files emitted by 'tar' $ diff ../file-list1 ../file-list2 | grep -E '^(<|>)' < ./Documentation/devicetree/bindings/.yamllint < ./drivers/clk/.kunitconfig < ./drivers/gpu/drm/tests/.kunitconfig < ./drivers/hid/.kunitconfig < ./fs/ext4/.kunitconfig < ./fs/fat/.kunitconfig < ./kernel/kcsan/.kunitconfig < ./lib/kunit/.kunitconfig < ./mm/kfence/.kunitconfig < ./tools/testing/selftests/arm64/tags/ < ./tools/testing/selftests/arm64/tags/.gitignore < ./tools/testing/selftests/arm64/tags/Makefile < ./tools/testing/selftests/arm64/tags/run_tags_test.sh < ./tools/testing/selftests/arm64/tags/tags_test.c < ./tools/testing/selftests/kvm/.gitignore < ./tools/testing/selftests/kvm/Makefile < ./tools/testing/selftests/kvm/config < ./tools/testing/selftests/kvm/settings The source tarball contains most of files that are tracked by git.

setlocalversion: use only the correct release tag for git-describe
Currently, setlocalversion uses any annotated tag for git-describe. If we are at a tagged commit, it will not append the commit hash. $ git checkout v6.2-rc1^ $ make -s defconfig kernelrelease 6.1.0-14595-g292a089d78d3 $ git tag -a foo -m foo $ make -s kernelrelease 6.1.0 If a local tag 'foo' exists, it pretends to be a released version '6.1.0', while there are many commits on top of it. The output should be consistent irrespective of such a local tag. Pass the correct release tag to --match option of git-describe. In the mainline kernel, the SUBLEVEL is always '0', which is omitted from the tag. KERNELVERSION annotated tag 6.1.0 -> v6.1 (mainline) 6.2.0-rc5 -> v6.2-rc5 (mainline, release candidate) 6.1.7 -> v6.1.7 (stable) To preserve the behavior in linux-next, use the tag derived from localversion* files if exists. In linux-next, the local version is specified by the localversion-next file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

kbuild: Provide a version of merge_into_defconfig without override warnings
While warning on overridden Kconfig options is a good default for merging config fragements sometimes that is our explicit intent and the warnings are unhelpful, add a new merge_into_defconfig_override which does the merge but with warnings suppressed. Since merge_into_defconfig accepts any number of fragments it is difficult to allow it to accept the flag.

scripts: merge_config: Add option to suppress warning on overrides
Currently merge_config.sh will unconditionally warn if a fragment overrides any already set symbol. This is generally desirable but is inconvenient in cases where we want to create a fragment which disables unwanted options in the base configuration, for example when attempting to produce a smaller version of another configuration. Add an option -Q which will suppress these warnings.

kbuild: do not automatically add -w option to modpost
When there is a missing input file (vmlinux.o or Module.symvers), you are likely to get a ton of unresolved symbols. Currently, Kbuild automatically adds the -w option to allow module builds to continue with warnings instead of errors. This may not be what the user expects because it is generally more useful to catch all possible issues at build time instead of at run time. Let's not do what the user did not ask. If you still want to build modules anyway, you can proceed by explicitly setting KBUILD_MODPOST_WARN=1. Since you may miss a real issue, you need to be aware of what you are doing.
