[Qemu-devel] [PATCH 0/3] linux-user: Implement missing *xattr calls

From: Peter Maydell
Subject: [Qemu-devel] [PATCH 0/3] linux-user: Implement missing *xattr calls
Date: Wed, 14 Dec 2011 15:37:16 +0000

These patches implement the missing *xattr syscalls:
 fsetattr, fgetattr, fremovexattr, flistxattr
 lsetattr, lgetattr, lremovexattr, llistxattr

They also fix a bug in the existing code where we weren't allowing a
NULL value pointer.

Tested with the testcases in crackerjack. (There are some cases where
we don't behave exactly like the native kernel:
 * we check for bad pointers earlier, so tend to return EFAULT when the
   kernel might return EINVAL in a "caller did two wrong things" case
 * we insist on the whole of the caller's buffer being writable whereas
   the kernel only cares about being able to write the data it actually
   needs, so we will fail EFAULT some bad callers that the kernel doesn't
I don't think these are important.)

Peter Maydell (3):
  linux-user: Allow NULL value pointer in setxattr and getxattr
  linux-user/syscall.c: Implement f and l versions of
  linux-user: Implement *listxattr syscalls
