<civodul>any idea why pipe2 is not (not really) implemented in libc?

<civodul>currently hurd/pipe2.c reads:

<civodul> if (flags & ~(O_CLOEXEC | O_NONBLOCK))

<civodul> return __hurd_fail (EINVAL);

<damo22>civodul: in words of our maintainer: Contributions welcome!

<civodul>i'm just wondering if there's a reason that made it hard to implement

<damo22>sorry im not sure

<civodul>maybe we first need socketpair to honor SOCK_CLOEXEC and SOCK_NONBLOCK?

<civodul>actually it does already

*civodul thinks out loud

<damo22>wouldnt that be flags & (O_CLOEXEC | O_NONBLOCK) ?

<damo22>if it were to fail due to one of those flags?

<damo22>so its all the other flags?

<damo22>is the ~() a bug perhaps?

<civodul>damo22: oh you're right, i'm misreading it

<civodul>no we're fine, pfew :-)

<damo22>i had a bit of practice with bitwise ops :)

<civodul>heh, thanks :-)

<damo22>what are you trying to do with pipe2?

<damo22>i dont really know what pipe2 is for

<civodul>it lets you pass additional flags, O_CLOEXEC and O_NONBLOCK

<civodul>so you can atomically create file descriptors with the right flags

<civodul>i'm using it in shepherd and wanted to make sure it's implemented on GNU/Hurd

<damo22>civodul: looks like it is implemented, but O_DIRECT is not supported

<damo22>youpi: inet_ntoa is thread safe apparently

<iska>what's the status on SMP?

<Pellescours>iska: still wip

<iska>Pellescours: that's the status of the entire hurd basically x3

<Pellescours>iska: you’ll be able to see progress here (https://github.com/AlmuHS/GNUMach_SMP/tree/smp_stage2), I don’t know more
