In cachefiles_check_volume_xattr(), the error returned by vfs_getxattr()
is not passed to ret, so it ends up returning -ESTALE, which leads to an
endless loop as follows:
cachefiles_acquire_volume
retry:
ret = cachefiles_check_volume_xattr
ret = -ESTALE
xlen = vfs_getxattr // return -EIO
// The ret is not updated when xlen < 0, so -ESTALE is returned.
return ret
// Supposed to jump out of the loop at this judgement.
if (ret != -ESTALE)
goto error_dir;
cachefiles_bury_object
// EIO causes rename failure
goto retry;
Hence propagate the error returned by vfs_getxattr() to avoid the above
issue. Do the same in cachefiles_check_auxdata().
