| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 7a0496056064 ("kbuild: fix DT binding schema rule to detect command line changes"), this rule is every time re-run even if you change nothing. cmd_dtc takes one additional parameter to pass to the -O option of dtc. We need to pass 'yaml' to if_changed_rule. Otherwise, cmd-check invoked from if_changed_rule is false positive.

For instance: long work_on_cpu(int cpu, long (*fn) (void *, void * arg) in driver-api/basics.html is missing a ')' separating the "void *" of the 'fn' arguments from the ", void * arg" which is an argument to work_on_cpu(). Add the missing close-paren, so that we render the prototype correctly: long work_on_cpu(int cpu, long (*fn)(void *), void * arg) (Note that Sphinx stops rendering a space between the '(fn*)' and the '(void *)' once it gets something that's syntactically valid.)

* kbuild: add dummy toolchains to enable all cc-option etc. in KconfigMasahiro Yamada2020-04-094-0/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Staring v4.18, Kconfig evaluates compiler capabilities, and hides CONFIG options your compiler does not support. This works well if you configure and build the kernel on the same host machine. It is inconvenient if you prepare the .config that is carried to a different build environment (typically this happens when you package the kernel for distros) because using a different compiler potentially produces different CONFIG options than the real build environment. So, you probably want to make as many options visible as possible. In other words, you need to create a super-set of CONFIG options that cover any build environment. If some of the CONFIG options turned out to be unsupported on the build machine, they are automatically disabled by the nature of Kconfig. However, it is not feasible to get a full-featured compiler for every arch. This issue was discussed here: https://lkml.org/lkml/2019/12/9/620 Other than distros, savedefconfig is also a problem. Some arch sub-systems periodically resync defconfig files. If you use a less-capable compiler for savedefconfig, options that do not meet 'depends on $(cc-option,...)' will be forcibly disabled. So, 'make defconfig && make savedefconfig' may silently change the behavior. This commit adds a set of dummy toolchains that pretend to support any feature. Most of compiler features are tested by cc-option, which simply checks the exit code of $(CC). The dummy tools are shell scripts that always exit with 0. So, $(cc-option, ...) is evaluated as 'y'. There are more complicated checks such as: scripts/gcc-x86_{32,64}-has-stack-protector.sh scripts/gcc-plugin.sh scripts/tools-support-relr.sh scripts/dummy-tools/gcc passes all checks. From the top directory of the source tree, you can do: $ make CROSS_COMPILE=scripts/dummy-tools/ oldconfig Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Philipp Rudo <prudo@linux.ibm.com> Tested-by: Jeremy Cline <jcline@redhat.com>
* kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=yMasahiro Yamada2020-04-091-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kbuild supports not only obj-y but also lib-y to list objects linked to vmlinux. The difference between them is that all the objects from obj-y are forcibly linked to vmlinux, whereas the objects from lib-y are linked as needed; if there is no user of a lib-y object, it is not linked. lib-y is intended to list utility functions that may be called from all over the place (and may be unused at all), but it is a problem for EXPORT_SYMBOL(). Even if there is no call-site in the vmlinux, we need to keep exported symbols for the use from loadable modules. Commit 7f2084fa55e6 ("[kbuild] handle exports in lib-y objects reliably") worked around it by linking a dummy object, lib-ksyms.o, which contains references to all the symbols exported from lib.a in that directory. It uses the linker script command, EXTERN. Unfortunately, the meaning of EXTERN of ld.lld is different from that of ld.bfd. Therefore, this does not work with LD=ld.lld (CBL issue #515). Anyway, the build rule of lib-ksyms.o is somewhat tricky. So, I want to get rid of it. At first, I was thinking of accumulating lib-y objects into obj-y (or even replacing lib-y with obj-y entirely), but the lib-y syntax is used beyond the ordinary use in lib/ and arch/*/lib/. Examples: - drivers/firmware/efi/libstub/Makefile builds lib.a, which is linked into vmlinux in the own way (arm64), or linked to the decompressor (arm, x86). - arch/alpha/lib/Makefile builds lib.a which is linked not only to vmlinux, but also to bootloaders in arch/alpha/boot/Makefile. - arch/xtensa/boot/lib/Makefile builds lib.a for use from arch/xtensa/boot/boot-redboot/Makefile. One more thing, adding everything to obj-y would increase the vmlinux size of allnoconfig (or tinyconfig). For less impact, I tweaked the destination of lib.a at the top Makefile; when CONFIG_MODULES=y, lib.a goes to KBUILD_VMLINUX_OBJS, which is forcibly linked to vmlinux, otherwise lib.a goes to KBUILD_VMLINUX_LIBS as before. The size impact for normal usecases is quite small since at lease one symbol in every lib-y object is eventually called by someone. In case you are intrested, here are the figures. x86_64_defconfig: text data bss dec hex filename 19566602 5422072 1589328 26578002 1958c52 vmlinux.before 19566932 5422104 1589328 26578364 1958dbc vmlinux.after The case with the biggest impact is allnoconfig + CONFIG_MODULES=y. ARCH=x86 allnoconfig + CONFIG_MODULES=y: text data bss dec hex filename 1175162 254740 1220608 2650510 28718e vmlinux.before 1177974 254836 1220608 2653418 287cea vmlinux.after Hopefully this is still not a big deal. The per-file trimming with the static library is not so effective after all. If fine-grained optimization is desired, some architectures support CONFIG_LD_DEAD_CODE_DATA_ELIMINATION, which trims dead code per-symbol basis. When LTO is supported in mainline, even better optimization will be possible.

* kbuild: Enable -Wtautological-compareNathan Chancellor2020-04-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently, we disable -Wtautological-compare, which in turn disables a bunch of more specific tautological comparison warnings that are useful for the kernel such as -Wtautological-bitwise-compare. See clang's documentation below for the other warnings that are suppressed by -Wtautological-compare. Now that all of the major/noisy warnings have been fixed, enable -Wtautological-compare so that more issues can be caught at build time by various continuous integration setups. -Wtautological-constant-out-of-range-compare is kept disabled under a normal build but visible at W=1 because there are places in the kernel where a constant or variable size can change based on the kernel configuration. These are not fixed in a clean/concise way and the ones I have audited so far appear to be harmless. It is not a subgroup but rather just one warning so we do not lose out on much coverage by default.

* ubsan: split "bounds" checker from other optionsKees Cook2020-04-071-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to do kernel builds with the bounds checker individually available, introduce CONFIG_UBSAN_BOUNDS, with the remaining options under CONFIG_UBSAN_MISC. For example, using this, we can start to expand the coverage syzkaller is providing. Right now, all of UBSan is disabled for syzbot builds because taken as a whole, it is too noisy. This will let us focus on one feature at a time. For the bounds checker specifically, this provides a mechanism to eliminate an entire class of array overflows with close to zero performance overhead (I cannot measure a difference). In my (mostly) defconfig, enabling bounds checking adds ~4200 checks to the kernel. Performance changes are in the noise, likely due to the branch predictors optimizing for the non-fail path. Some notes on the bounds checker: - it does not instrument {mem,str}*()-family functions, it only instruments direct indexed accesses (e.g. "foo[i]"). Dealing with the {mem,str}*()-family functions is a work-in-progress around CONFIG_FORTIFY_SOURCE[1]. - it ignores flexible array members, including the very old single byte (e.g. "int foo[1];") declarations. (Note that GCC's implementation appears to ignore _all_ trailing arrays, but Clang only ignores empty, 0, and 1 byte arrays[2].)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch series "ubsan: Split out bounds checker", v5. This splits out the bounds checker so it can be individually used. This is enabled in Android and hopefully for syzbot. Includes LKDTM tests for behavioral corner-cases (beyond just the bounds checker), and adjusts ubsan and kasan slightly for correct panic handling. This patch (of 6): The Undefined Behavior Sanitizer can operate in two modes: warning reporting mode via lib/ubsan.c handler calls, or trap mode, which uses __builtin_trap() as the handler. Using lib/ubsan.c means the kernel image is about 5% larger (due to all the debugging text and reporting structures to capture details about the warning conditions). Using the trap mode, the image size changes are much smaller, though at the loss of the "warning only" mode. In order to give greater flexibility to system builders that want minimal changes to image size and are prepared to deal with kernel code being aborted and potentially destabilizing the system, this introduces CONFIG_UBSAN_TRAP.

* checkpatch: add command-line option for TAB sizeAntonio Borneo2020-04-071-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel coding style requires a size of 8 characters for both TAB and indentation, and such value is embedded as magic value allover the checkpatch script. This makes hard to reuse the script by other projects with different requirements in their coding style (e.g. OpenOCD [1] requires TAB size of 4 characters [2]). Replace the magic value 8 with a variable. Add a command-line option "--tab-size" to let the user select a TAB size value other than 8.

* checkpatch: fix multiple const * typesAntonio Borneo2020-04-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1574a29f8e76 ("checkpatch: allow multiple const * types") claims to support repetition of pattern "const *", but it actually allows only one extra instance. Check the following lines int a(char const * const x[]); int b(char const * const *x); int c(char const * const * const x[]); int d(char const * const * const *x); with command ./scripts/checkpatch.pl --show-types -f filename to find that only the first line passes the test, while a warning is triggered by the other 3 lines: WARNING:FUNCTION_ARGUMENTS: function definition argument 'char const * const' should also have an identifier name The reason is that the pattern match halts at the second asterisk in the line, thus the remaining text starting with asterisk fails to match a valid name for a variable. Fixed by replacing "?" (Match 1 or 0 times) with "{0,4}" (Match no more than 4 times) in the regular expression. Fix also the similar test for types in unusual order.

* checkpatch: support "base-commit:" formatJohn Hubbard2020-04-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support the get-lore-mbox.py tool described in [1], I ran: git format-patch --base=<commit> --cover-letter <revrange> ... which generated a "base-commit: <commit-hash>" tag at the end of the cover letter. However, checkpatch.pl generated an error upon encounting "base-commit:" in the cover letter: "ERROR: Please use git commit description style..." ... because it found the "commit" keyword, and failed to recognize that it was part of the "base-commit" phrase, and as such, should not be subjected to the same commit description style rules. Update checkpatch.pl to include a special case for "base-commit:" (at the start of the line, possibly with some leading whitespace) so that that tag no longer generates a checkpatch error.

R. Silva. 7) Align XDP statistics names across several drivers for consistency, from Lorenzo Bianconi. 8) Add various pieces of infrastructure for offloading conntrack, and make use of it in mlx5 driver, from Paul Blakey. 9) Allow using listening sockets in BPF sockmap, from Jakub Sitnicki. 10) Lots of parallelization improvements during configuration changes in mlxsw driver, from Ido Schimmel. 11) Add support to devlink for generic packet traps, which report packets dropped during ACL processing. And use them in mlxsw driver. From Jiri Pirko. 12) Support bcmgenet on ACPI, from Jeremy Linton. 13) Make BPF compatible with RT, from Thomas Gleixnet, Alexei Starovoitov, and your's truly. 14) Support XDP meta-data in virtio_net, from Yuya Kusakabe. 15) Fix sysfs permissions when network devices change namespaces, from Christian Brauner. 16) Add a flags element to ethtool_ops so that drivers can more simply indicate which coalescing parameters they actually support, and therefore the generic layer can validate the user's ethtool request. Use this in all drivers, from Jakub Kicinski. 17) Offload FIFO qdisc in mlxsw, from Petr Machata. 18) Support UDP sockets in sockmap, from Lorenz Bauer. 19) Fix stretch ACK bugs in several TCP congestion control modules, from Pengcheng Yang. 20) Support virtual functiosn in octeontx2 driver, from Tomasz Duszynski. 21) Add region operations for devlink and use it in ice driver to dump NVM contents, from Jacob Keller. 22) Add support for hw offload of MACSEC, from Antoine Tenart. 23) Add support for BPF programs that can be attached to LSM hooks, from KP Singh. 24) Support for multiple paths, path managers, and counters in MPTCP. From Peter Krystad, Paolo Abeni, Florian Westphal, Davide Caratti, and others. 25) More progress on adding the netlink interface to ethtool, from Michal Kubecek" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2121 commits) net: ipv6: rpl_iptunnel: Fix potential memory leak in rpl_do_srh_inline cxgb4/chcr: nic-tls stats in ethtool net: dsa: fix oops while probing Marvell DSA switches net/bpfilter: remove superfluous testing message net: macb: Fix handling of fixed-link node net: dsa: ksz: Select KSZ protocol tag netdevsim: dev: Fix memory leak in nsim_dev_take_snapshot_write net: stmmac: add EHL 2.5Gbps PCI info and PCI ID net: stmmac: add EHL PSE0 & PSE1 1Gbps PCI info and PCI ID net: stmmac: create dwmac-intel.c to contain all Intel platform net: dsa: bcm_sf2: Support specifying VLAN tag egress rule net: dsa: bcm_sf2: Add support for matching VLAN TCI net: dsa: bcm_sf2: Move writing of CFP_DATA(5) into slicing functions net: dsa: bcm_sf2: Check earlier for FLOW_EXT and FLOW_MAC_EXT net: dsa: bcm_sf2: Disable learning for ASP port net: dsa: b53: Deny enslaving port 7 for 7278 into a bridge net: dsa: b53: Prevent tagged VLAN on port 7 for 7278 net: dsa: b53: Restore VLAN entries upon (re)configuration net: dsa: bcm_sf2: Fix overflow checks hv_netvsc: Remove unnecessary round_up for recv_completion_cnt ...
