Hi, **Kibana version: 7.10.2** I am trying to build kibana-oss rpm from src code (for centos env) following the procedure from [developer guide](https://www.elastic.co/guide/en/kibana/master/development-getting-started.html). The required pre-req dependencies (git,gcc etc) are installed, **kibana bootstrap runs successfully** , however **building the rpm fails at the task 'Patching platform-specific native modules'.** Cmd used: `yarn build --rpm --skip-node-download --oss --skip-archives --release -v --allow-root` ```auto info [kibana-oss] Patching platform-specific native modules │ debg Patching re2 binaries from https://github.com/uhop/node-re2/releases/download/1.15.4/linux-x64-64.gz to /home/workspace/kibana/build/oss/kibana-7.10.2-linux-aarch64/node_modules/re2/build/Release/re2.node │ debg Deleting patterns: ['/home/workspace/kibana/build/oss/kibana-7.10.2-linux-aarch64/node_modules/re2/build/Release/re2.node'] │ debg Patching re2 binaries from https://github.com/uhop/node-re2/releases/download/1.15.4/darwin-x64-64.gz to /home/workspace/kibana/build/oss/kibana-7.10.2-darwin-x86_64/node_modules/re2/build/Release/re2.node │ debg Deleting patterns: ['/home/workspace/kibana/build/oss/kibana-7.10.2-darwin-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Patching re2 binaries from https://github.com/uhop/node-re2/releases/download/1.15.4/linux-x64-64.gz to /home/workspace/kibana/build/oss/kibana-7.10.2-linux-x86_64/node_modules/re2/build/Release/re2.node │ debg Deleting patterns: ['/home/workspace/kibana/build/oss/kibana-7.10.2-linux-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Patching re2 binaries from https://github.com/uhop/node-re2/releases/download/1.15.4/win32-x64-64.gz to /home/workspace/kibana/build/oss/kibana-7.10.2-windows-x86_64/node_modules/re2/build/Release/re2.node │ debg Deleting patterns: ['/home/workspace/kibana/build/oss/kibana-7.10.2-windows-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Deleted 1 files/directories │ sill Deleted: ['/home/workspace/kibana/build/oss/kibana-7.10.2-linux-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Deleted 1 files/directories │ sill Deleted: ['/home/workspace/kibana/build/oss/kibana-7.10.2-windows-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Deleted 1 files/directories │ sill Deleted: ['/home/workspace/kibana/build/oss/kibana-7.10.2-darwin-x86_64/node_modules/re2/build/Release/re2.node'] │ debg Deleted 1 files/directories │ sill Deleted: ['/home/workspace/kibana/build/oss/kibana-7.10.2-linux-aarch64/node_modules/re2/build/Release/re2.node'] │ debg Attempting download of https://github.com/uhop/node-re2/releases/download/1.15.4/linux-x64-64.gz e743587bc96314edf10c3e659c03168bc374a5cd9a6623ee99d989251e331f28 │ debg Attempting download of https://github.com/uhop/node-re2/releases/download/1.15.4/win32-x64-64.gz b33de62cda24fb02dc80a19fb79977d686468ac746e97cd211059d2d4c75d529 │ debg Attempting download of https://github.com/uhop/node-re2/releases/download/1.15.4/darwin-x64-64.gz 595c6653d796493ddb288fc0732a0d1df8560099796f55a1dd242357d96bb8d6 │ debg Attempting download of https://github.com/uhop/node-re2/releases/download/1.15.4/linux-x64-64.gz e743587bc96314edf10c3e659c03168bc374a5cd9a6623ee99d989251e331f28 │ debg Download failed: socket hang up │ debg Deleting downloaded data at /home/workspace/kibana/.native_modules/re2/darwin-x64-64.gz │ debg Retrying -

I am successfully able to download the 3 pkgs i.e. darwin-x64-64.gz, linux-x64-64.gz and win32-x64-64.gz via direct wget from the said urls. Q1: What could be the reason for this error? Are any additional npm/yarn settings needed for this step to proceed? (The same settings/procedure worked fine while building kibana 7.0, 7.8). Q2: As a workaround, I tried disabling the download & gzip method in file src/dev/build/tasks/patch\_native\_modules\_task.ts (i.e. lines 95-111) ```auto await deleteAll([extractPath], log); // await download({ // log, // url: archive.url, // destination: downloadPath, // sha256: archive.sha256, // retries: 3, // }); // switch (pkg.extractMethod) { // case 'gunzip': // await gunzip(downloadPath, extractPath); // break; // case 'untar': // await untar(downloadPath, extractPath); // break; // default: // throw new Error(`Extract method of ${pkg.extractMethod} is not supported`); // } ``` With these changes, the yarn build stage completed successfully and the rpm got built. I validated this built rpm and it seems to work fine. Just one observation was that the rpm size increased by 30mb (as certain files in node\_modules/re2 didnt get cleaned up probably due to my change here). What is the significance of this task 'Patching platform-specific native modules'? Is it not important in this case as the rpm works fine with my changes? If this task is not required entirely, is there a cmd line argument for yarn build that would skip this part without modifying src code the way I have done here? Pls note - I am interested in building oss rpm only for centos env (not all platforms like windows etc). Any pointers would be highly appreciated. Thanks! ---

That step addresses [CVE-2020-7016](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-7016) It's possible the issue you're running into is that step does not respect the proxy you have configured. Is it possible to run this from a machine with direct internet access not requiring a proxy? ---

Thanks for the response. No i cannot run this from a machine with direct access to the internet and can only work through using proxy. I do not enable timelion in my deployments, so in that case is it okay to skip this task as the CVE fix does not impact anyways? Also follow-up question to that, is there a better way to skip this task (than the one I have tried by commenting the mentioned lines in the code)? ---
