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

[Peter Maydell <peter.maydell@linaro.org>]

These patches implement the missing *xattr syscalls:
 listxattr
 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
    set/get/removexattr
  linux-user: Implement *listxattr syscalls
