tls: allow enabling the TLS debug trace by sam-github · Pull Request #27376 · nodejs/node

sam-github · 2019-04-24T00:35:29Z

Enable the same trace output that the OpenSSL s_client and s_server
support with their `-trace` option. This is invaluable when debugging
reports of TLS bugs as well as when debugging the internal TLS
implementation.

The PR is unfortunately large, because I had to regenerate the openssl configuration. The last commit is quite small.

@nodejs/platform-aix Any idea why https://github.com/sam-github/node/blob/tls-trace/src/tls_wrap.cc#L915-L931 or something in https://github.com/sam-github/node/blob/tls-trace/deps/openssl/openssl/ssl/t1_trce.c would pulling in an undefined C++ iostreams symbol?

sam-github · 2019-04-24T17:14:25Z

The 1.1.1 shared failure is because the tests expect SSL_trace to be available, but the openssl linked against doesn't have it. The code handles it, the tests don't. I'll fix that.

If you strip the whitespace changes from the first commit, it slims down to a more manageable +252 −652.

You could trim it down even further by dropping the mostly irrelevant buildinf.h changes but that's arguably falsifying history. :-)

bnoordhuis · 2019-04-25T21:19:03Z

Is it even worth exposing OPENSSL_NO_SSL_TRACE? We don't expose any of the other OPENSSL_NO_* defines either.
I'd remove it if it's just for feature detection in the test. You could make TLSWrap::EnableTrace() return a boolean or throw an exception and use that for feature detection.

Its annoyingly more complex than it might seem. The return value of enableTrace isn't seen on the server side (its called before the user code gets the TLSSocket), and since the tests have to call them in a sub-process to catch stderr, it makes a simple test skip more fragile than needed. I'll move these to the internal binding so they aren't visible in our API.

sam-github · 2019-04-25T22:51:56Z

@bnoordhuis Do you have any idea why all the whitespace changes are ocurring? I see it even on master when I do a straight regen of the config: sam-github@e8e97c1

The timestamp changes are expected, but the whitespace in the asm files is not. I am the one who generated them last time, on the same laptop, though perhaps perl, or binutils, or something, has gotten a routine update, but I haven't figure out what changed yet.

sam-github · 2019-04-25T23:14:18Z

I changed the PR base to https://github.com/nodejs/node/tree/configure-openssl-trace, it makes it much easier to review. I'll redo the constants tomorrow.

Notable changes: * deps: * Updated llhttp to 1.1.3. This fixes a bug that made Node.js' HTTP parser refuse any request URL that contained the "|" (vertical bar) character. #27595 * tls: * Added an `enableTrace()` method to `TLSSocket` and an `enableTrace` option to `tls.createServer()`. When enabled, TSL packet trace information is written to `stderr`. This can be used to debug TLS connection problems. #27497 #27376 * cli: * Added a `--trace-tls` command-line flag that enables tracing of TLS connections without the need to modify existing application code. #27497 * Added a `--cpu-prof-interval` command-line flag. It can be used to specify the sampling interval for the CPU profiles generated by `--cpu-prof`. #27535 * module: * Added the `createRequire()` method. It allows to create a require function from a file URL object, a file URL string or an absolute path string. The existing `createRequireFromPath()` method is now deprecated #27405. * Throw on `require('./path.mjs')`. This is technically a breaking change that should have landed with Node.js 12.0.0. It is necessary to have this to keep the possibility for a future minor version to load ES Modules with the require function. #27417 * repl: * The REPL now supports multi-line statements using `BigInt` literals as well as public and private class fields and methods. #27400 * The REPL now supports tab autocompletion of file paths with `fs` methods. #26648 * meta: * Added Christian Clauss (https://github.com/cclauss) to collaborators. #27554 PR-URL: #27578

@sam-github , should this land on v10.x? Please add the lts-watch-v10.x if so

sam-github · 2019-09-04T01:39:42Z

It would be useful on v10.x, but I've no idea how hard it will be to backport.
