2017-12-07netlink: Relax attr validation for fixed length typesDavid Ahern1-6/+16
Commit 28033ae4e0f5 ("net: netlink: Update attr validation to require exact length for some types") requires attributes using types NLA_U* and NLA_S* to have an exact length. This change is exposing bugs in various userspace commands that are sending attributes with an invalid length (e.g., attribute has type NLA_U8 and userspace sends NLA_U32). While the commands are clearly broken and need to be fixed, users are arguing that the sudden change in enforcement is breaking older commands on newer kernels for use cases that otherwise "worked". Relax the validation to print a warning mesage similar to what is done for messages containing extra bytes after parsing.

Attributes using NLA_U* and NLA_S* (where * is 8, 16,32 and 64) are expected to be an exact length. Split these data types from nla_attr_minlen into nla_attr_len and update validate_nla to require the attribute to have exact length for them.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree. Basically, updates to the conntrack core, enhancements for nf_tables, conversion of netfilter hooks from linked list to array to improve memory locality and asorted improvements for the Netfilter codebase. More specifically, they are: 1) Add expection to hashes after timer initialization to prevent access from another CPU that walks on the hashes and calls del_timer(), from Florian Westphal. 2) Don't update nf_tables chain counters from hot path, this is only used by the x_tables compatibility layer. 3) Get rid of nested rcu_read_lock() calls from netfilter hook path. Hooks are always guaranteed to run from rcu read side, so remove nested rcu_read_lock() where possible. Patch from Taehee Yoo. 4) nf_tables new ruleset generation notifications include PID and name of the process that has updated the ruleset, from Phil Sutter. 5) Use skb_header_pointer() from nft_fib, so we can reuse this code from the nf_family netdev family. Patch from Pablo M. Bermudo. 6) Add support for nft_fib in nf_tables netdev family, also from Pablo. 7) Use deferrable workqueue for conntrack garbage collection, to reduce power consumption, from Patch from Subash Abhinov Kasiviswanathan. 8) Add nf_ct_expect_iterate_net() helper and use it. From Florian Westphal. 9) Call nf_ct_unconfirmed_destroy only from cttimeout, from Florian. 10) Drop references on conntrack removal path when skbuffs has escaped via nfqueue, from Florian. 11) Don't queue packets to nfqueue with dying conntrack, from Florian. 12) Constify nf_hook_ops structure, from Florian. 13) Remove neededlessly branch in nf_tables trace code, from Phil Sutter. 14) Add nla_strdup(), from Phil Sutter. 15) Rise nf_tables objects name size up to 255 chars, people want to use DNS names, so increase this according to what RFC 1035 specifies. Patch series from Phil Sutter. 16) Kill nf_conntrack_default_on, it's broken. Default on conntrack hook registration on demand, suggested by Eric Dumazet, patch from Florian. 17) Remove unused variables in compat_copy_entry_from_user both in ip_tables and arp_tables code. Patch from Taehee Yoo. 18) Constify struct nf_conntrack_l4proto, from Julia Lawall. 19) Constify nf_loginfo structure, also from Julia. 20) Use a single rb root in connlimit, from Taehee Yoo. 21) Remove unused netfilter_queue_init() prototype, from Taehee Yoo. 22) Use audit_log() instead of open-coding it, from Geliang Tang. 23) Allow to mangle tcp options via nft_exthdr, from Florian. 24) Allow to fetch TCP MSS from nft_rt, from Florian. This includes a fix for a miscalculation of the minimal length. 25) Simplify branch logic in h323 helper, from Nick Desaulniers. 26) Calculate netlink attribute size for conntrack tuple at compile time, from Florian. 27) Remove protocol name field from nf_conntrack_{l3,l4}proto structure. From Florian. 28) Remove holes in nf_conntrack_l4proto structure, so it becomes smaller. From Florian. 29) Get rid of print_tuple() indirection for /proc conntrack listing. Place all the code in net/netfilter/nf_conntrack_standalone.c. Patch from Florian. 30) Do not built in print_conntrack() if CONFIG_NF_CONNTRACK_PROCFS is off. From Florian. 31) Constify most nf_conntrack_{l3,l4}proto helper functions, from Florian. 32) Fix broken indentation in ebtables extensions, from Colin Ian King. 33) Fix several harmless sparse warning, from Florian. 34) Convert netfilter hook infrastructure to use array for better memory locality, joint work done by Florian and Aaron Conole. Moreover, add some instrumentation to debug this. 35) Batch nf_unregister_net_hooks() calls, to call synchronize_net once per batch, from Florian. 36) Get rid of noisy logging in ICMPv6 conntrack helper, from Florian. 37) Get rid of obsolete NFDEBUG() instrumentation, from Varsha Rao. 38) Remove unused code in the generic protocol tracker, from Davide Caratti.

2017-07-30net netlink: Add new type NLA_BITFIELD32Jamal Hadi Salim1-0/+30
Generic bitflags attribute content sent to the kernel by user. With this netlink attr type the user can either set or unset a flag in the kernel. The value is a bitmap that defines the bit values being set The selector is a bitmask that defines which value bit is to be considered. A check is made to ensure the rules that a kernel subsystem always conforms to bitflags the kernel already knows about. i.e if the user tries to set a bit flag that is not understood then the _it will be rejected_. In the most basic form, the user specifies the attribute policy as: [ATTR_GOO] = { .type = NLA_BITFIELD32, .validation_data = &myvalidflags }, where myvalidflags is the bit mask of the flags the kernel understands. If the user _does not_ provide myvalidflags then the attribute will also be rejected. Examples: value = 0x0, and selector = 0x1 implies we are selecting bit 1 and we want to set its value to 0. value = 0x2, and selector = 0x2 implies we are selecting bit 2 and we want to set its value to 1.

2017-06-16networking: make skb_put & friends return void pointersJohannes Berg1-1/+1
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c.

This is a problem since the string comparison will not match as the last byte may be not the nul-termination.
