Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac 2013-10-16 23:27:59 +02:00			`/* Generated by gensyscalls.py. Do not edit. */`

Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

Add extended attribute (xattr) system call wrappers to bionic. The xattr system calls are required for the SE Android userspace in order to get and set file security contexts. In particular, libselinux requires these calls. Change-Id: I78f5eb3d8f3384aed0a5e7c6a6f001781d982017 2012-01-13 13:45:16 +01:00

Add cfi directives to all arm assembly. Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the custom arm assembly has no unwind information. Adding the proper cfi directives for these and removing the arm directives. Update the gensyscalls.py script to add these cfi directives for the generated assembly. Also fix the references to non-uapi headers to the proper uapi header. In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not needed at all. The unwinder (libunwind) is able to properly unwind using the normal abort. After this change, I can unwind through the system calls again.

Use the kernel's MAX_ERRNO in the syscall stubs. Bug: http://code.google.com/p/android/issues/detail?id=53104 Change-Id: Iaabf7025b153e96dc5eca231a33a32d4cb7d8116 2013-03-12 22:57:30 +01:00			`cmn r0, #(MAX_ERRNO + 1)`

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			`b __set_errno_internal`
