  1. Gluon 2017.1.6 (in development)
  2. ===============================
  3. Bugfixes
  4. ~~~~~~~~
  5. * Remove broken DNS cache feature
  6. (`#1362 <https://github.com/freifunk-gluon/gluon/issues/1362>`_)
  7. It was found that dnsmasq does not handle all answer records
  8. equally. In particular, its cached answers are missing DNSKEY and DS
  9. records, breaking DNSSEC validation on clients.
  10. Nodes can still resolve the next-node hostname locally and will continue to
  11. work as DNS forwarders. The DNS cache feature may return if dnsmasq is fixed
  12. or if we switch to a different resolver.
  13. * Ensure that corefiles are stored in /tmp rather than cluttering the root
  14. filesystem
  15. (`00df8b76e54c <https://github.com/freifunk-gluon/gluon/commit/00df8b76e54c9bb89299df4b2ec49e972046d6b6>`_)
  16. Nodes upgrades from Gluon v2016.2.x or earlier did not set kernel.core_pattern
  17. correctly, leading to corefiles being stored in the current directory (usually
  18. / for system services) in the case of crashes.
  19. This is a regression introduced in Gluon v2017.1.
  20. * Only request a single IPv6 address instead of a prefix on the WAN interface
  21. (`5db54ba78c3 <https://github.com/freifunk-gluon/gluon/commit/5db54ba78c3e245f06e4a407371608f6cb247b49>`_)
  22. * Fix signal graph on status page when there are many neighbours
  23. (packages/`d1e0b6e0bdae <https://github.com/freifunk-gluon/packages/commit/d1e0b6e0bdaea14d8b9425cee6ca83087be1a905>`_)
  24. * Fix config files managed by opkg not being saved on sysupgrades on ar71xx-tiny
  25. (LEDE/`17c0362178ca <https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=17c0362178caf837680a4631b8d0de94e5393448>`_,
  26. LEDE/`75be005e8bdc <https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=75be005e8bdcbf86f9ad167a8737126dda98a444>`_)
  27. * Fix kernel crash in batman-adv-14
  28. (`#1358 <https://github.com/freifunk-gluon/gluon/issues/1358>`_)
  29. Starting with Gluon v2017.1, respondd could trigger a kernel crash caused by
  30. a use-after-free in batman-adv-14, in particular after a gateway disappeared.
  31. batman-adv-15 is not affected.
  32. * Increase bridge multicast querier timeout ("robustness") to avoid
  33. "querier appeared/disappeared" log spam by batman-adv in the presence of
  34. an external querier
  35. (`e305a8c01917 <https://github.com/freifunk-gluon/gluon/commit/e305a8c019179472dbfc6fccea6c87cf40c08a75>`_)
  36. * Fix "broken pipe" log spam caused by the status page
  37. (`883c32f2f1dc <https://github.com/freifunk-gluon/gluon/commit/883c32f2f1dc368626069865c07a5701e3e9bcae>`_)
  38. * Reduce memory limit of WLAN packet queues to 256KB on devices with small RAM
  39. (`e63c6ca01f50 <https://github.com/freifunk-gluon/gluon/commit/e63c6ca01f50c96d76e5570faa290617a8a312b4>`_)
  40. Will hopefully make out-of-memory crashes in busy meshes less likely.
  41. * Improve image validation for TP-Link CPE/WBS 210/510 and make it ready for
  42. future images
  43. (LEDE/`6577fe2198f5 <https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=6577fe2198f5c75acb1dba789941d96a036f4dae>`_)
  44. Future OpenWrt/Gluon images will move the image metadata ("support-list") of
  45. the CPE/WBS 210/510 images to a different offset. Make sysupgrade ready
  46. to allow installing such images.
  47. This change was also backported to Gluon v2016.2.x to allow direct updates
  48. to future Gluon master versions without installing v2017.1.x first.
  49. * Sporadic segfaults of busybox (ash) when running shell scripts on ar71xx
  50. have disappeared with the latest updates
  51. (`#1157 <https://github.com/freifunk-gluon/gluon/issues/1157>`_)
  52. Known issues
  53. ~~~~~~~~~~~~
  54. * Default TX power on many Ubiquiti devices is too high, correct offsets are unknown (`#94 <https://github.com/freifunk-gluon/gluon/issues/94>`_)
  55. Reducing the TX power in the Advanced Settings is recommended.
  56. * The MAC address of the WAN interface is modified even when Mesh-on-WAN is disabled (`#496 <https://github.com/freifunk-gluon/gluon/issues/496>`_)
  57. This may lead to issues in environments where a fixed MAC address is expected (like VMware when promicious mode is disallowed).
  58. * Inconsistent respondd API (`#522 <https://github.com/freifunk-gluon/gluon/issues/522>`_)
  59. The current API is inconsistent and will be replaced eventually. The old API will still be supported for a while.
  60. * Frequent reboots due to out-of-memory on weak hardware in larger meshes
  61. (`#1243 <https://github.com/freifunk-gluon/gluon/issues/1243>`_)
