Add accept4() syscall Add accept4() using SYSCALLS.TXT and gensyscall Change-Id: I6f19f29144186d15d46423e10f2cc4b4223719c6 2014-03-26 14:50:01 +01:00			`/* Generated by gensyscalls.py. Do not edit. */`

Mark sockets on creation (socket()) and accept4(). Remove the separate syscall for accept() and implement it as accept4(..., 0). Change-Id: Ib0b8f5d7c5013b91eae6bbc3847852eb355c7714 2014-05-19 22:39:57 +02:00			`ENTRY(__accept4)`

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps. (cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.) Bug: 17423135 Change-Id: I6b6d7a05dda85f923d22e5ffd169a91e23499b7b 2014-09-09 00:25:01 +02:00			`call __set_errno_internal`
