[B.A.T.M.A.N.] [PATCH] batman-adv: handle race condition for claims also in batadv_bla_rx

by Simon Wunderlich

From: Andreas Pape <apape(a)phoenixcontact.com> Like in the case of the patch for batadv_bla_tx to handle a race condition when claiming a mac address for bla, a similar situation can occur when claiming is triggered via batadv_bla_rx. This patch solves this with a similar approach as for batadv_bla_tx.

[B.A.T.M.A.N.] Set preferred mesh backhaul link

by Carlito Nueno

Hi, I have two access points with 2.4GHz and 5GHz radios. Node A and Node B Both radios are mesh via batman-adv. I can see them with batctl if. Node A is server - batctl gw server Node B is client So here is my problem: When I check batctl gwl, it shows that it uses Node A's 2.4GHz interface. How can I set it so that it prefers 5GHz as mesh backhaul? Thanks!

[B.A.T.M.A.N.] [PATCH 0/6] alfred: License cleanup

by Sven Eckelmann

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 also go through all files of alfred (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 in the batman-adv patchset) * explicitly mark remaining files as licensed under the GPL-2.0 Kind regards, Sven Sven Eckelmann (6): alfred: Rename LICENSE to Linux's LICENSES/preferred/GPL-2.0 alfred: Add License-Filename to GPL-2.0 files alfred: Import Linux's LICENSES/preferred/MIT alfred: Add SPDX license identifier above copyright header alfred: Mark remaining files as GPL-2.0 alfred: Change batman_adv.h license to MIT .gitattributes | 3 +++ CHANGELOG.license | 2 ++ LICENSE => LICENSES/preferred/GPL-2.0 | 13 +++++++++++++ LICENSES/preferred/MIT | 30 ++++++++++++++++++++++++++++++ Makefile | 2 ++ README.license | 2 ++ alfred.h | 5 +++-- batadv_query.c | 5 +++-- batadv_query.h | 5 +++-- batadv_querynl.c | 5 +++-- batadv_querynl.h | 5 +++-- batman_adv.h | 27 +++++++++++++++++---------- bitops.h | 1 + client.c | 5 +++-- debugfs.c | 5 +++-- debugfs.h | 5 +++-- gpsd/Makefile | 2 ++ gpsd/alfred-gpsd.c | 5 +++-- gpsd/alfred-gpsd.h | 5 +++-- gpsd/man/alfred-gpsd.8 | 2 ++ hash.c | 5 +++-- hash.h | 5 +++-- list.h | 5 +++-- main.c | 5 +++-- man/alfred.8 | 2 ++ netlink.c | 5 +++-- netlink.h | 5 +++-- netsock.c | 5 +++-- packet.h | 5 +++-- recv.c | 5 +++-- send.c | 5 +++-- server.c | 5 +++-- unix_sock.c | 5 +++-- util.c | 5 +++-- vis/Makefile | 2 ++ vis/man/batadv-vis.8 | 2 ++ vis/vis.c | 5 +++-- vis/vis.h | 5 +++-- 38 files changed, 155 insertions(+), 60 deletions(-) create mode 100644 CHANGELOG.license rename LICENSE => LICENSES/preferred/GPL-2.0 (97%) create mode 100644 LICENSES/preferred/MIT create mode 100644 README.license -- 2.11.0

[B.A.T.M.A.N.] [PATCH 0/6] batman-adv: Include cleanup

by Sven Eckelmann

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. Kind regards, Sven Sven Eckelmann (6): batman-adv: include gfp.h for GFP_* defines batman-adv: include build_bug.h for BUILD_BUG_ON define batman-adv: Include net.h for net_ratelimited_function batman-adv: include kobject.h for kobject_* functions batman-adv: Remove unused sched.h include batman-adv: compat: Map to linux/nl80211.h for Linux < 3.7 compat-include/linux/build_bug.h | 34 ++++++++++++++++++++++++++++++++++ compat-include/uapi/linux/nl80211.h | 4 ++++ net/batman-adv/bat_iv_ogm.c | 2 +- net/batman-adv/bat_v_elp.c | 2 +- net/batman-adv/bat_v_ogm.c | 2 +- net/batman-adv/bridge_loop_avoidance.c | 2 +- net/batman-adv/debugfs.c | 1 - net/batman-adv/distributed-arp-table.c | 2 +- net/batman-adv/fragmentation.c | 2 +- net/batman-adv/gateway_client.c | 2 +- net/batman-adv/hard-interface.c | 2 +- net/batman-adv/hash.c | 2 +- net/batman-adv/icmp_socket.c | 1 + net/batman-adv/log.c | 1 + net/batman-adv/main.c | 4 ++-- net/batman-adv/multicast.c | 2 +- net/batman-adv/netlink.c | 2 +- net/batman-adv/network-coding.c | 3 ++- net/batman-adv/originator.c | 2 +- net/batman-adv/send.c | 2 +- net/batman-adv/soft-interface.c | 2 +- net/batman-adv/sysfs.c | 3 ++- net/batman-adv/tp_meter.c | 4 ++-- net/batman-adv/translation-table.c | 5 +++-- net/batman-adv/tvlv.c | 2 +- 25 files changed, 66 insertions(+), 24 deletions(-) create mode 100644 compat-include/linux/build_bug.h -- 2.11.0

[B.A.T.M.A.N.] [PATCH 0/3] batman-adv: Convert CHANGELOG/README to reStructuredText

by Sven Eckelmann

Hi, I was talking today with Simon about the "License cleanup" changes. He would prefer when the *.license files don't exist (when possible). 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
