Backtraces and best way to check cause
by Nigel Kukard 30 Jul '17

30 Jul '17

Hi guys, I'm wondering what would be the best way to try track the cause of these two backtraces. I'm trying to replace a Quagga 1.1.1 box with FRR 2.0 but am blocked by the below. There are about 30 or so external peers. 4 internal private peers. About 40 or so route maps and maybe 100 prefix lists.

NOTICE: Planned style conversion Monday, Jul 17
by Quentin Young 25 Jul '17

25 Jul '17

Hi folks, In a technical meeting many weeks ago we decided to restyle the codebase to Linux kernel style with the intent of easing maintenance burdens, increasing readability and having a common standard across all FRR components. With our pull request backlog presently at a minimum, the plan is to bite the bullet and convert FRR's master branch to Linux kernel style on Monday, July 17. The tooling for this task will be a Python wrapper for the clang-format <https://clang.llvm.org/docs/ClangFormat.html> source code formatter. The script and configuration file for clang-format will be checked in over the coming days prior to conversion. This patch will not be submitted in a pull request. This will be a direct push to master. All stable branches will remain as-is. Code submissions against those branches -- which should by now be limited to bug fixes -- should continue to follow the style guide present in those branches. Going forward we will require all patch submissions against master to conform to Linux kernel style, with some exceptions (DEFUNS primarily) that will be documented prior to conversion and which the Python script knows about. Recommended procedure will be to run the indent script over new code prior to submission. David has offered to write a helper script to ease merges / rebases for currently open pull requests and local branches. Please familiarize yourself with the kernel style guide located here: https://www.kernel.org/doc/html/v4.10/process/coding-style.html It will also be useful to have passing familiarity with clang-format: https://clang.llvm.org/docs/ClangFormat.html https://clang.llvm.org/docs/ClangFormatStyleOptions.html The first page contains instructions on how to integrate it with Vim and Emacs should you wish to do so. The tools are located in the LLVM clang repository, which you can clone by following the instructions here: https://clang.llvm.org/get_started.html Quentin

Возможная блокировка github в Российской федерации / Possible blocking of github in the Russian Federation
by Алексей Болдырев 20 Jul '17

20 Jul '17

Обращаю внимание разработчиков и тестеров из России, что в России готовится закон о запрете анонимайзеров и VPN для частных лиц: https://www.linux.org.ru/forum/talks/13555716 Также возможно то, что в России будет возможно заблокирован github, что создаст сложности разработчикам и тестировщикам из Российской федерации. По этому я предлагаю сделать копию кода FRRouting на локальный сервер, а также поддерживать этот локальный сервер. -- I draw the attention of developers and testers from Russia that the law on banning anonymizers and VPN for private individuals is being prepared in Russia: Https://www.linux.org.ru/forum/talks/13555716 It is also possible that github will be blocked in Russia, which will create difficulties for developers and testers from the Russian Federation. Therefore, I propose to make a copy of the FRRouting code on the local server, and also support this local server.
