Subject: [PATCH 32/33] linux-user: zero fstat buffer to initialize nsec fields
|
||
|
|
|
||
|
|
The fstat implementation does not initialize the nanosecond fields in the
|
||
|
|
stat buffer; this caused funny values to turn up there, preventing, for
|
||
|
|
instance, cp -p from preserving timestamps because utimensat rejected
|
||
|
|
the out-of-bounds nanosecond values. Resetting the entire structure
|
||
|
|
to zero fixes that.
