SubjectRe: [PATCH 03/18] flag parameters: paccept
From: Ulrich Drepper <>
Date: Sun, 4 May 2008 23:42:46 -0400

> This patch is by far the most complex in the series. It adds a new syscall
> paccept. This syscall differs from accept in that it adds (at the userlevel)
> two additional parameters:
> - a signal mask
> - a flags value
> The flags parameter can be used to set flag like SOCK_CLOEXEC. This is
> imlpemented here as well. Some people argued that this is a property
> which should be inherited from the file desriptor for the server but
> this is against POSIX. Additionally, we really want the signal mask
> parameter as well (similar to pselect, ppoll, etc). So an interface
> change in inevitable.
> The flag value is the same as for socket and socketpair. I think
> diverging here will only create confusion. Similar to the filesystem
> interfaces where the use of the O_* constants differs, it is acceptable
> here.
> The signal mask is handled as for pselect etc. The mask is temporarily
> installed for the thread and removed before the call returns. I modeled
> the code after pselect. If there is a problem it's likely also in
> pselect.
