2020-10-26treewide: Convert macro and uses of __section(foo) to __section("foo")Joe Perches1-2/+2
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

2020-10-22bpf: Fix bpf_redirect_neigh helper api to support supplying nexthopToke Høiland-Jørgensen1-0/+1
Based on the discussion in [0], update the bpf_redirect_neigh() helper to accept an optional parameter specifying the nexthop information. This makes it possible to combine bpf_fib_lookup() and bpf_redirect_neigh() without incurring a duplicate FIB lookup - since the FIB lookup helper will return the nexthop information even if no neighbour is present, this can simply be passed on to bpf_redirect_neigh() if bpf_fib_lookup() returns BPF_FIB_LKUP_RET_NO_NEIGH. Thus fix & extend it before helper API is frozen.

This isn't just a theoretical problem: on Arch Linux, `hostname` is provided by `inetutils`, which isn't part of the base distribution. ./scripts/mkcompile_h: line 38: hostname: command not found Use `uname -n` instead, which is more likely to be available (and mandated by standards).

2020-10-16ubsan: introduce CONFIG_UBSAN_LOCAL_BOUNDS for ClangGeorge Popescu1-1/+9
When the kernel is compiled with Clang, -fsanitize=bounds expands to -fsanitize=array-bounds and -fsanitize=local-bounds. Enabling -fsanitize=local-bounds with Clang has the unfortunate side-effect of inserting traps; this goes back to its original intent, which was as a hardening and not a debugging feature [1]. The same feature made its way into -fsanitize=bounds, but the traps remained. For that reason, -fsanitize=bounds was split into 'array-bounds' and 'local-bounds' [2]. Since 'local-bounds' doesn't behave like a normal sanitizer, enable it with Clang only if trapping behaviour was requested by CONFIG_UBSAN_TRAP=y. Add the UBSAN_BOUNDS_LOCAL config to Kconfig.ubsan to enable the 'local-bounds' option by default when UBSAN_TRAP is enabled.

2020-10-16checkpatch: add new warnings to author signoff checks.Dwaipayan Ray1-16/+77
The author signed-off-by checks are currently very vague. Cases like same name or same address are not handled separately. For example, running checkpatch on commit be6577af0cef ("parisc: Add atomic64_set_release() define to avoid CPU soft lockups"), gives: WARNING: Missing Signed-off-by: line by nominal patch author 'John David Anglin <dave.anglin@bell.net>' The signoff line was: "Signed-off-by: Dave Anglin <dave.anglin@bell.net>" Clearly the author has signed off but with a slightly different version of his name. A more appropriate warning would have been to point out at the name mismatch instead. Previously, the values assumed by $authorsignoff were either 0 or 1 to indicate whether a proper sign off by author is present. Extended the checks to handle four new cases. $authorsignoff values now denote the following: 0: Missing sign off by patch author. 1: Sign off present and identical. 2: Addresses and names match, but comments differ. "James Watson(JW) <james@gmail.com>", "James Watson <james@gmail.com>" 3: Addresses match, but names are different. "James Watson <james@gmail.com>", "James <james@gmail.com>" 4: Names match, but addresses are different. "James Watson <james@watson.com>", "James Watson <james@gmail.com>" 5: Names match, addresses excluding subaddress details (RFC 5233) match.

2020-10-16checkpatch: fix multi-statement macro checks for while blocks.Dwaipayan Ray1-3/+4
Checkpatch.pl doesn't have a check for excluding while (...) {...} blocks from MULTISTATEMENT_MACRO_USE_DO_WHILE error. For example, running checkpatch.pl on the file mm/maccess.c in the kernel generates the following error: ERROR: Macros with complex values should be enclosed in parentheses +#define copy_from_kernel_nofault_loop(dst, src, len, type, err_label) \ + while (len >= sizeof(type)) { \ + __get_kernel_nofault(dst, src, type, err_label); \ + dst += sizeof(type); \ + src += sizeof(type); \ + len -= sizeof(type); \ + } The error is misleading for this case. Enclosing it in parentheses doesn't make any sense. Checkpatch already has an exception list for such common macro types. Added a new exception for while (...) {...} style blocks to the same. In addition, the brace flatten logic was modified by changing the substitution characters from "1" to "1u". This was done to ensure that macros in the form "#define foo(bar) while(bar){bar--;}" were also correctly procecssed.

2020-10-16checkpatch: extend author Signed-off-by check for split From: headerDwaipayan Ray1-0/+4
Checkpatch did not handle cases where the author From: header was split into multiple lines. The author identity could not be resolved and checkpatch generated a false NO_AUTHOR_SIGN_OFF warning. A typical example is commit e33bcbab16d1 ("tee: add support for session's client UUID generation"). When checkpatch was run on this commit, it displayed: "WARNING:NO_AUTHOR_SIGN_OFF: Missing Signed-off-by: line by nominal patch author ''" This was due to split header lines not being handled properly and the author himself wrote in commit cd2614967d8b ("checkpatch: warn if missing author Signed-off-by"): "Split From: headers are not fully handled: only the first part is compared." Support split From: headers by correctly parsing the header extension lines. RFC 5322, Section-2.2.3 stated that each extended line must start with a WSP character (a space or htab). The solution was therefore to concatenate the lines which start with a WSP to get the correct long header.

Kconfig allows to customize the CONFIG_ prefix via the $CONFIG_ environment variable. Out-of-tree projects may therefore use Kconfig with a different prefix, or they may use a custom configuration tool which does not use the CONFIG_ prefix at all. Such projects may still want to adhere to the Linux kernel coding style and run checkpatch.pl. One example is OP-TEE [1] which does not use Kconfig but does have configuration options prefixed with CFG_. It also mostly follows the kernel coding style and therefore being able to use checkpatch is quite valuable. To make this possible, add the --kconfig-prefix command line option.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: - Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. - Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). - Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. - Allow more than 255 IPv4 multicast interfaces. - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. - In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. - Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. - Allow more calls to same peer in RxRPC. - Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. - Add TC actions for implementing MPLS L2 VPNs. - Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. - Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. - Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. - Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. - Support sleepable BPF programs, initially targeting LSM and tracing. - Add bpf_d_path() helper for returning full path for given 'struct path'. - Make bpf_tail_call compatible with bpf-to-bpf calls. - Allow BPF programs to call map_update_elem on sockmaps. - Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). - Support listing and getting information about bpf_links via the bpf syscall. - Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). - Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. - Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). - In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. - Add XDP support for Intel's igb driver. - Support offloading TC flower classification and filtering rules to mscc_ocelot switches. - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. - Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. - Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. - Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. - Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. - Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete). * tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2583 commits) Revert "bpfilter: Fix build error with CONFIG_BPFILTER_UMH" net, sockmap: Don't call bpf_prog_put() on NULL pointer bpf, selftest: Fix flaky tcp_hdr_options test when adding addr to lo bpf, sockmap: Add locking annotations to iterator netfilter: nftables: allow re-computing sctp CRC-32C in 'payload' statements net: fix pos incrementment in ipv6_route_seq_next net/smc: fix invalid return code in smcd_new_buf_create() net/smc: fix valid DMBE buffer sizes net/smc: fix use-after-free of delayed events bpfilter: Fix build error with CONFIG_BPFILTER_UMH cxgb4/ch_ipsec: Replace the module name to ch_ipsec from chcr net: sched: Fix suspicious RCU usage while accessing tcf_tunnel_info bpf: Fix register equivalence tracking. rxrpc: Fix loss of final ack on shutdown rxrpc: Fix bundle counting for exclusive connections netfilter: restore NF_INET_NUMHOOKS ibmveth: Identify ingress large send packets. ibmveth: Switch order of ibmveth_helper calls. cxgb4: handle 4-tuple PEDIT to NAT mode translation selftests: Add VRF route leaking tests ...

Address several issues related to pointing to the wrong line number: 1) ensure that line numbers will always be initialized When section is the default (Description), the line number is not initializing, producing this: $ ./scripts/kernel-doc --enable-lineno ./drivers/media/v4l2-core/v4l2-mem2mem.c|less **Description** #define LINENO 0 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue Which is not right. Ensure that the line number will always be there. After applied, the result now points to the right location: **Description** #define LINENO 410 In case of streamoff or release called on any context, 1] If the context is currently running, then abort job will be called 2] If the context is queued, then the context will be removed from the job_queue 2) The line numbers for function prototypes are always + 1, because it is taken at the line after handling the prototype. Change the logic to point to the next line after the /** */ block; 3) The "DOC:" line number should point to the same line as this markup is found, and not to the next one. Probably part of the issues were due to a but that was causing the line number offset to be incremented by one, if --export were used. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-15scripts: kernel-doc: allow passing desired Sphinx C domain dialectMauro Carvalho Chehab1-8/+43
When kernel-doc is called via kerneldoc.py, there's no need to auto-detect the Sphinx version, as the Sphinx module already knows it. So, add an optional parameter to allow changing the Sphinx dialect. As kernel-doc can also be manually called, keep the auto-detection logic if the parameter was not specified. On such case, emit a warning if sphinx-build can't be found at PATH. I ended using a suggestion from Joe for using a more readable regex, instead of using a complex one with a hidden group like: m/^(\d+)\.(\d+)(?:\.?(\d+)?)/ in order to get the optional <patch> argument.

2020-10-15scripts: kernel-doc: don't mangle with parameter listMauro Carvalho Chehab1-12/+14
While kernel-doc needs to parse parameters in order to identify its name, it shouldn't be touching the type, as parsing it is very difficult, and errors happen. One current error is when parsing this parameter: const u32 (*tab)[256] Found at ./lib/crc32.c, on this function: u32 __pure crc32_be_generic (u32 crc, unsigned char const *p, size_t len, const u32 (*tab)[256], u32 polynomial); The current logic mangles it, producing this output: const u32 ( *tab That's something that it is not recognizeable.

2020-10-14kbuild: deb-pkg: clean up package name variablesMasahiro Yamada1-9/+9
Hard-code the names of linux-headers and debug packages in the control file. The kernel package is different for ARCH=um. Change the code for better readability. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-10-14kbuild: deb-pkg: do not build linux-headers package if CONFIG_MODULES=nMasahiro Yamada2-9/+16
Since commit 269a535ca931 ("modpost: generate vmlinux.symvers and reuse it for the second modpost"), with CONFIG_MODULES disabled, "make deb-pkg" (or "make bindeb-pkg") fails with: find: ‘Module.symvers’: No such file or directory If CONFIG_MODULES is disabled, it doesn't really make sense to build the linux-headers package. Fixes: 269a535ca931 ("modpost: generate vmlinux.symvers and reuse it for the second modpost") Reported-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
