As the callback should +be paying attention to the value of *error (to be fixed in the next +patch), we are better off ensuring that we pass in a pointer to a +known-zero value. Besides, passing in &errno carries a risk that if +the callback uses any other library function that alters errno prior +to dereferncing *error, it will no longer see the value we passed in. +Thus, it is easier to use a dummy variable on the stack than to mess +around with errno and it's magic macro expansion into a thread-local +storage location. + +Note that several callsites then check if the callback returned -1, +and if so assume that the callback has caused errno to now have a sane +value to pass on to perror. In theory, the fact that we are no longer +passing in &errno means that if the callback assigns into *error but +did not otherwise affect errno (a tenuous assumption, given our +argument above that we could not even guarantee that the callback does +not accidentally alter errno prior to reading *error), our perror call +would no longer reflect the intended error value from the callback. +But in practice, since the callback never actually returned -1, nor +even assigned into *error, the call to perror is dead code; although I +have chosen to defer that additional cleanup to the next patch. + +Message-Id: <20220203202558.203013-5-eblake@redhat.com> +Acked-by: Richard W.M.

This can result in the silent creation of a corrupted +image in two different ways: when a read fails, we blindly wrote +garbage to the destination; when a write fails, we did not flag that +the destination was not written. + +Since nbdcopy already calls exit() on a synchronous read or write +failure to a file, doing the same for an asynchronous op to an NBD +server is the simplest solution. A nicer solution, but more invasive +to code and thus not done here, might be to allow up to N retries of +the transaction (in case the read or write failure was transient), or +even having a mode where as much data is copied as possible (portions +of the copy that failed would be logged on stderr, and nbdcopy would +still fail with a non-zero exit status, but this would copy more than +just stopping at the first error, as can be done with rsync or +ddrescue). + +Note that since we rely on auto-retiring and do NOT call +nbd_aio_command_completed, our completion callbacks must always return +1 (if they do not exit() first), even when acting on *error, so as not +leave the command allocated until nbd_close. As such, there is no +sane way to return an error to a manual caller of the callback, and +therefore we can drop dead code that calls perror() and exit() if the +callback "failed". It is also worth documenting the contract on when +we must manually call the callback during the asynch_zero callback, so +that we do not leak or double-free the command; thankfully, all the +existing code paths were correct. + +The added testsuite script demonstrates several scenarios, some of +which fail without the rest of this patch in place, and others which +showcase ways in which sparse images can bypass errors. + +Once backports are complete, a followup patch on the main branch will +edit docs/libnbd-security.pod with the mailing list announcement of +the stable branch commit ids and release versions that incorporate +this fix. + +Reported-by: Nir Soffer +Fixes: bc896eec4d ("copy: Implement multi-conn, multiple threads, multiple requests in flight.", v1.5.6) +Fixes: https://bugzilla.redhat.com/2046194 +Message-Id: <20220203202558.203013-6-eblake@redhat.com> +Acked-by: Richard W.M.
