Google dropped support for ppc64le out of their SSL libraries but Raptor is still maintaining boringssl ppc64le support in their patchset. They only test it in Debian though (which AFAIK uses ieee-long-double) and they suspect the issue might relate to something in the compiler around 128 bit types. Reproducible: Always

Yeah, I suspect you're right. I'd be very interested in if it works with the new profiles if you can try them out (take a backup first please, see the comments in bug 882815 for how; i'd strongly recommend rebuilding everything after you rebuild gcc/binutils/glibc too.)
The error is in their patchset and not in the compiler. gmult_func is defined as: typedef void (*gmult_func)(uint8_t Xi[16], const u128 Htable[16]); But in the patchset gcm_gmult_p8 is: void gcm_gmult_p8(uint64_t Xi[2], const u128 Htable[16]);
removal: https://github.com/google/boringssl/commit/5fdc03f74adfd3d270aa6f64b3f3050c19e52e49#diff-5ded05174f8be4359aeee63a4e1c84b83123cd6dec5e1a12afc9f7a8d1ec6a26L313 upstream: https://github.com/openssl/openssl/blob/9f5102bffc8bb3a9b02a0a5e3c1de4326622fe04/crypto/modes/gcm128.c#L400 Their patchset has (in gcm.c): ``` +#elif defined(GHASH_ASM_PPC64LE) + if (CRYPTO_is_PPC64LE_vcrypto_capable()) { + gcm_init_p8(out_table, H); + *out_mult = gcm_gmult_p8; + *out_hash = gcm_ghash_p8; + return; + } #endif ``` which is the same as what it was w/ boringssl before, so I imagine it's been broken on ppc64le for a while, and what actually happened was clang 16 got stabled -> made incompatible-func-ptr-types an error by default and nobody had noticed until now?
I use clang 16 since the very first day of the release, so I guess it must not have been a problem before 115 otherwise I would have noticed. Debian doesn't use clang 16 for sure.
Same here. www-client/chromium-116.0.5845.140:0/stable::gentoo (kangie PMed me the ebuild). logs and info upcoming ``` Unavailable repository 'steam-overlay' referenced by masters entry in

Should be fixed here: https://salsa.debian.org/chromium-team/chromium/-/commit/f1431a48728a3cdcdc8cd08331a5c9f96748c953 This patch doesn't change functionality, and SSL is still verified to work. The underlying assembler routine isn't aware of the function call definitions in the first place, and continues to operate on the provided data in the same manner regardless of whether the function call prototype declares a pointer to two 64-bit ints or 16 bytes. Tested to function identically as before on a Talos II machine with Chromium 116 patch level 140.
Thanks! I'm trying it now and I will eventually submit a PR for 115 and 116. Since that should hopefully lead to a working electron-26+, do you know if there is any ETA for v8_sandbox on ppc64le? Currently vscode does not work anymore on latest versions of electron due to the lack of v8_sandbox. To be precise it's node-spdlog which gets pulled in by vscode and doesn't work with latest electron. See https://github.com/microsoft/vscode/issues/182743 and https://github.com/PF4Public/gentoo-overlay/issues/219 I've tried to disable v8_sandbox and fix the symbols mismatch in the headers but I didn't get it working either. I'm currently patching electron-19 with all kinds of compiler flags and python 3.11 patches to keep it working, but I will most likely be driven away from the Talos 2 as my main workstation if I can't get vscode to compile on modern electron.

Let me know if it doesn't fix things, otherwise we should be good to go. > Since that should hopefully lead to a working electron-26+, do you know if > there is any ETA for v8_sandbox on ppc64le? To be quite honest I wasn't aware of the missing support. Is there a bug open anywhere on it, and what is the easiest way to attempt to compile v8_sandbox? If I can avoid going down rabbit holes chasing older or wrong versions of the feature that's needed here I can focus more on the porting effort / figuring out why it isn't enabled on ppc64le yet. Thanks!

The easiest way to reproduce the issue is this: https://github.com/microsoft/node-spdlog/issues/40 vscode makes use of node-spdlog and that's where the crash occurs, making it far easier to reproduce and debug. But I highly suggest to read this thread: https://github.com/microsoft/vscode/issues/182743 One of vscode developers pointed out that v8_enable_sandbox ends up being disabled on ppc64le since v8_enable_external_code_space is disabled by default and that might be the issue. You can also quickly skim through this thread: https://github.com/PF4Public/gentoo-overlay/issues/219 It's the least interesting IMO but a couple of comments towards the end might be worth reading.

Timothy did you have any chance to look why node-spdlog fails to run its test suite?

I'll start digging > into that early next week. Just as a quick update here, I am working on adding the missing sandbox support to v8 for ppc64. This is the fastest route to fixing not only this issue but other subtle incompatibilities that may arise over time, plus with pointer compression it should reduce memory usage on ppc64 for some of the more complex server-side Web applications.
Awesome, keep me posted.

Thanks! Would you mind rebasing on top of electron 26 so I can test it with vscode (which is quite picky about the electron version)? I've tried myself and for the most part it's straightforward enough, but I'm not sure about some parts.
Created attachment 872384 [details, diff] Electron v8 ppc64 sandbox backport

It looks like Electron 22's v8 comes from Chromiumn 116, and not only predates pointer sandboxing but is also unbuildable on my v8 development box (Debian Sid) due to libc++ errors. I've attempted a backport in the attached patch, but since I cannot complete the build process it is currently untested. Can you give it a try and see if it works? Thanks!

I guess it fails because of the libstdc++ from gcc 13: https://github.com/PF4Public/gentoo-overlay/issues/261#issuecomment-1740873223 If that's the case you can use Chromium's bundled libcxx. Anyway I'm having a look right now.

Could you open up a new bug report on the Electron issues? We've managed to merge two completely different threads on this report and I'd like to have a clean bug report to forward upstream. Thanks!
> Could you open up a new bug report on the Electron issues? I would have loved to do so, bug unfortunately Gentoo doesn't have an electron ebuild in tree. I maintain ppc64 electron on the pf4public overlay, so maybe I can open a bug report there?
I've made it far (and even managed to get vscode working with some hacks) but unfortunately the v8 sandbox patch makes node segfault while compiling vscode. Here is the PR where I'm trying to get it working: https://github.com/PF4Public/gentoo-overlay/pull/265 I wonder if adding the patch to node-v18.16.1/deps/v8 as well might fix it but unfortunately the patch needs to be rebased against it in order to apply (and it's just a guess).
