[B.A.T.M.A.N.] [PATCH 0/9] batman-adv: License cleanup
by Sven Eckelmann 06 Dec '17

06 Dec '17

Hi, the kernel community is currently trying to make the licensing status more clear in each file. This is mostly done by adding SPDX license identifiers and defining a set of rules how these license related information has to be stored. I've used this opportunity to go through all files (for example with FSFE's `reuse lint`) and to annotate the files according to the "Linux licensing rules" and FSFE's REUSE practices. There are two things which could be seen as controversial: * change of batman_adv.h to the Linux preferred license (I am waiting for Acks) * explicitly mark remaining files as licensed under the GPL-2.0 Kind regards, Sven Sven Eckelmann (9): batman-adv: Add GPL-2.0 as Linux's LICENSES/preferred/GPL-2.0 batman-adv: Add License-Filename to GPL-2.0 files batman-adv: Add SPDX license identifier above copyright header batman-adv: Add SPDX license identifier to batman-adv.rst batman-adv: Add license header to Kconfig batman-adv: Add license headers to compat files batman-adv: Mark remaining files as GPL-2.0 batman-adv: Change batman_adv.h license to MIT batman-adv: Import Linux's LICENSES/preferred/MIT .gitattributes | 3 + CHANGELOG.license | 2 + Documentation/networking/batman-adv.rst | 2 + LICENSES/preferred/GPL-2.0 | 352 ++++++++++++++++++++++++++++++++ LICENSES/preferred/MIT | 30 +++ MAINTAINERS.license | 2 + Makefile | 3 +- README.external.license | 2 + compat-include/linux/average.h | 3 + compat-include/linux/cache.h | 3 + compat-include/linux/etherdevice.h | 3 + compat-include/linux/ethtool.h | 3 + compat-include/linux/export.h | 3 + compat-include/linux/genetlink.h | 3 + compat-include/linux/if_bridge.h | 23 +++ compat-include/linux/if_ether.h | 3 + compat-include/linux/if_vlan.h | 3 + compat-include/linux/igmp.h | 23 +++ compat-include/linux/kernel.h | 3 + compat-include/linux/kref.h | 3 + compat-include/linux/list.h | 3 + compat-include/linux/net.h | 3 + compat-include/linux/netdev_features.h | 3 + compat-include/linux/netdevice.h | 3 + compat-include/linux/netlink.h | 3 + compat-include/linux/nl80211.h | 23 +++ compat-include/linux/random.h | 3 + compat-include/linux/rculist.h | 3 + compat-include/linux/seq_file.h | 3 + compat-include/linux/skbuff.h | 3 + compat-include/linux/slab.h | 3 + compat-include/net/addrconf.h | 23 +++ compat-include/net/cfg80211.h | 23 +++ compat-include/net/genetlink.h | 3 + compat-include/net/ip6_checksum.h | 23 +++ compat-include/net/ipv6.h | 23 +++ compat-include/uapi/linux/nl80211.h | 23 +++ compat-patches/README | 2 + compat-patches/replacements.sh | 18 ++ compat-sources/Makefile | 19 ++ compat-sources/net/core/skbuff.c | 3 + compat-sources/net/ipv4/igmp.c | 3 + compat-sources/net/ipv6/mcast_snoop.c | 3 + compat.h | 3 + gen-compat-autoconf.sh | 18 ++ include/uapi/linux/batman_adv.h | 27 ++- net/batman-adv/Kconfig | 19 ++ net/batman-adv/Makefile | 3 +- net/batman-adv/bat_algo.c | 3 + net/batman-adv/bat_algo.h | 3 + net/batman-adv/bat_iv_ogm.c | 3 + net/batman-adv/bat_iv_ogm.h | 3 + net/batman-adv/bat_v.c | 3 + net/batman-adv/bat_v.h | 3 + net/batman-adv/bat_v_elp.c | 3 + net/batman-adv/bat_v_elp.h | 3 + net/batman-adv/bat_v_ogm.c | 3 + net/batman-adv/bat_v_ogm.h | 3 + net/batman-adv/bitarray.c | 3 + net/batman-adv/bitarray.h | 3 + net/batman-adv/bridge_loop_avoidance.c | 3 + net/batman-adv/bridge_loop_avoidance.h | 3 + net/batman-adv/debugfs.c | 3 + net/batman-adv/debugfs.h | 3 + net/batman-adv/distributed-arp-table.c | 3 + net/batman-adv/distributed-arp-table.h | 3 + net/batman-adv/fragmentation.c | 3 + net/batman-adv/fragmentation.h | 3 + net/batman-adv/gateway_client.c | 3 + net/batman-adv/gateway_client.h | 3 + net/batman-adv/gateway_common.c | 3 + net/batman-adv/gateway_common.h | 3 + net/batman-adv/hard-interface.c | 3 + net/batman-adv/hard-interface.h | 3 + net/batman-adv/hash.c | 3 + net/batman-adv/hash.h | 3 + net/batman-adv/icmp_socket.c | 3 + net/batman-adv/icmp_socket.h | 3 + net/batman-adv/log.c | 3 + net/batman-adv/log.h | 3 + net/batman-adv/main.c | 3 + net/batman-adv/main.h | 3 + net/batman-adv/multicast.c | 3 + net/batman-adv/multicast.h | 3 + net/batman-adv/netlink.c | 3 + net/batman-adv/netlink.h | 3 + net/batman-adv/network-coding.c | 3 + net/batman-adv/network-coding.h | 3 + net/batman-adv/originator.c | 3 + net/batman-adv/originator.h | 3 + net/batman-adv/packet.h | 3 + net/batman-adv/routing.c | 3 + net/batman-adv/routing.h | 3 + net/batman-adv/send.c | 3 + net/batman-adv/send.h | 3 + net/batman-adv/soft-interface.c | 3 + net/batman-adv/soft-interface.h | 3 + net/batman-adv/sysfs.c | 3 + net/batman-adv/sysfs.h | 3 + net/batman-adv/tp_meter.c | 3 + net/batman-adv/tp_meter.h | 3 + net/batman-adv/translation-table.c | 3 + net/batman-adv/translation-table.h | 3 + net/batman-adv/tvlv.c | 3 + net/batman-adv/tvlv.h | 3 + net/batman-adv/types.h | 3 + 106 files changed, 923 insertions(+), 12 deletions(-) create mode 100644 CHANGELOG.license create mode 100644 LICENSES/preferred/GPL-2.0 create mode 100644 LICENSES/preferred/MIT create mode 100644 MAINTAINERS.license create mode 100644 README.external.license -- 2.11.0

Hi, I went through the build_test.git's testhelpers/kernel_mappings.iwyu and cleaned that up a little bit. This requires that we have to adjust the batman-adv sources slighty. I have also found a build problem when you try to build B.A.T.M.A.N. V against Linux < 3.7 and fixed it in the same patchset.

[B.A.T.M.A.N.] [PATCH 0/8] batman-adv: kernel-doc enhancements
by Sven Eckelmann 06 Dec '17

06 Dec '17

Hi, more and more functions/struct/enums/... in batman-adv have at least some brief documentation. But there were still some externally visible (as "visible" in other source files) elements which completely missed any kind of kernel-doc. Accoring to the kernel-doc dicumentation [1], having these documented "properly" is currently a goal. This patchset now tries to unify the formatting slightly and then add more (brief) documentation to these elements. Kind regards, Sven [1] https://www.kernel.org/doc/html/v4.14/doc-guide/kernel-doc.html#recommendat… Sven Eckelmann (8): batman-adv: Add missing kernel-doc to packet.h batman-adv: Use parentheses in function kernel-doc batman-adv: Use inline kernel-doc for enum/struct batman-adv: Fix kernel-doc references to struct members batman-adv: Add kernel-doc to structs in headers batman-adv: Add kernel-doc to enums in headers batman-adv: Add kernel-doc to functions in headers batman-adv: Add kernel-doc to externally visible functions net/batman-adv/bat_algo.c | 34 +- net/batman-adv/bat_iv_ogm.c | 102 +- net/batman-adv/bat_v.c | 48 +- net/batman-adv/bat_v_elp.c | 24 +- net/batman-adv/bat_v_ogm.c | 34 +- net/batman-adv/bitarray.c | 2 +- net/batman-adv/bitarray.h | 9 +- net/batman-adv/bridge_loop_avoidance.c | 109 +- net/batman-adv/bridge_loop_avoidance.h | 4 +- net/batman-adv/debugfs.c | 28 +- net/batman-adv/distributed-arp-table.c | 77 +- net/batman-adv/distributed-arp-table.h | 6 +- net/batman-adv/fragmentation.c | 20 +- net/batman-adv/fragmentation.h | 2 +- net/batman-adv/gateway_client.c | 62 +- net/batman-adv/gateway_common.c | 27 +- net/batman-adv/gateway_common.h | 5 +- net/batman-adv/hard-interface.c | 62 +- net/batman-adv/hard-interface.h | 58 +- net/batman-adv/hash.c | 17 +- net/batman-adv/hash.h | 27 +- net/batman-adv/icmp_socket.c | 13 +- net/batman-adv/log.c | 17 + net/batman-adv/log.h | 61 +- net/batman-adv/main.c | 47 +- net/batman-adv/main.h | 120 +- net/batman-adv/multicast.c | 78 +- net/batman-adv/multicast.h | 16 +- net/batman-adv/netlink.c | 22 +- net/batman-adv/network-coding.c | 120 +- net/batman-adv/originator.c | 119 +- net/batman-adv/originator.h | 9 +- net/batman-adv/packet.h | 25 +- net/batman-adv/routing.c | 53 +- net/batman-adv/send.c | 63 +- net/batman-adv/send.h | 4 +- net/batman-adv/soft-interface.c | 61 +- net/batman-adv/sysfs.c | 52 +- net/batman-adv/sysfs.h | 13 + net/batman-adv/tp_meter.c | 70 +- net/batman-adv/translation-table.c | 226 ++-- net/batman-adv/tvlv.c | 38 +- net/batman-adv/types.h | 1992 ++++++++++++++++++++++---------- 43 files changed, 2694 insertions(+), 1282 deletions(-) -- 2.11.0

[B.A.T.M.A.N.] [PATCH] batman-adv: Fix lock for ogm cnt access in batadv_iv_ogm_calc_tq
by Sven Eckelmann 04 Dec '17

04 Dec '17

The originator node object orig_neigh_node is used to when accessing the bcast_own(_sum) and real_packet_count information. The access to them has to be protected with the spinlock in orig_neigh_node. But the function uses the lock in orig_node instead. This is incorrect because they could be two different originator node objects.

Luckily, I already wanted to convert these files (or at least the READMEs) to reStructuredText and I've already shown in these patchsets how the SPDX annotation should be done for the lrest files. So it was just logically to immediately post the conversion to rst and integration of this tag. We've also discussed how the changelog should look like. It should be simple and we only wanted to show the date (not the time) anymore. And the actual changelog lists should be kept (mostly untouched - beside some minor format fixes to make it reStructuredText compatible). This patchset is based on the "batman-adv: License cleanup" patchset. Kind regards, Sven Sven Eckelmann (3): batman-adv: Add .rst to README symlink batman-adv: Convert CHANGELOG to reStructuredText batman-adv: Convert README to reStructuredText CHANGELOG | 634 --------------------------------------------- CHANGELOG.license | 2 - CHANGELOG.rst | 666 ++++++++++++++++++++++++++++++++++++++++++++++++ README.external | 51 ---- README.external.license | 2 - README.external.rst | 59 +++++ README => README.rst | 0 7 files changed, 725 insertions(+), 689 deletions(-) delete mode 100644 CHANGELOG delete mode 100644 CHANGELOG.license create mode 100644 CHANGELOG.rst delete mode 100644 README.external delete mode 100644 README.external.license create mode 100644 README.external.rst rename README => README.rst (100%) -- 2.11.0
