Even if a device failed to plug, it's still a device

be freed automatically together with the device, but
freeing them any earlier - like it's done in the hotplug
error handling path right now - will give us a dangling
pointer and a segfault scenario.

Consider the following case:
 * secondary process receives the hotplug request IPC message
   * devargs are either created or updated
   * the bus is scanned
     * a new device object is created with the latest devargs
   * the device can't be plugged for whatever reason,
     bus->plug returns error
     * the devargs are freed, even though they're still referenced
       by the device object on the bus

For PCI devices, the generic device name comes from
a buffer within the devargs. Freeing those will make
EAL segfault whenever the device name is checked.

This patch just prevents the hotplug error handling
path from removing the devargs when there's a device
that references them. This is done by simply exiting
early from the hotplug function. As mentioned in the
beginning, those devargs will be freed later, together
with the device itself.

6 years agodoc: announce API change for cryptodev sym session
Konstantin Ananyev [Thu, 11 Oct 2018 14:20:24 +0000 (15:20 +0100)]
doc: announce API change for cryptodev sym session

Below are details and reasoning for proposed changes.

1.rte_cryptodev_sym_session_init()/ rte_cryptodev_sym_session_clear()
  operate based on cytpodev device id, though inside
  rte_cryptodev_sym_session device specific data is addressed
  by driver id (not device id).
  That creates a problem with current implementation when we have
  two or more devices with the same driver used by the same session.
  Consider the following example:

  struct rte_cryptodev_sym_session *sess;
  rte_cryptodev_sym_session_init(dev_id=X, sess, ...);
  rte_cryptodev_sym_session_init(dev_id=Y, sess, ...);
  rte_cryptodev_sym_session_clear(dev_id=X, sess);

  After that point if X and Y uses the same driver,
  then sess can't be used by device Y any more.
  The reason for that - driver specific (not device specific)
  data per session, plus there is no information
  how many device instances use that data.
  Probably the simplest way to deal with that issue -
  add a reference counter per each driver data.

2.rte_cryptodev_sym_session_set_user_data() and
  rte_cryptodev_sym_session_get_user_data() -
  with current implementation there is no defined way for the user to
  determine what is the max allowed size of the private data.
  rte_cryptodev_sym_session_set_user_data() just blindly copies
  user provided data without checking memory boundaries violation.
  To overcome that issue propose to add 'uint16_t priv_size' into
  rte_cryptodev_sym_session structure.

3.rte_cryptodev_sym_session contains an array of variable size for
  driver specific data.
  Though number of elements in that array is determined by static
  variable nb_drivers, that could be modified by
  rte_cryptodev_allocate_driver().
  That construction seems to work ok so far, as right now users register
  all their PMDs at startup, though it doesn't mean that it would always
  remain like that.
  To make it less error prone propose to add 'uint16_t nb_drivers'
  into the rte_cryptodev_sym_session structure.
  At least that allows related functions to check that provided
  driver id wouldn't overrun variable array boundaries,
  again it allows to determine size of already allocated session
  without accessing global variable.

4.#2 and #3 above implies that now each struct rte_cryptodev_sym_session
  would have sort of readonly type data (init once at allocation time,
  keep unmodified through session life-time).
  That requires more changes in current cryptodev implementation:
  Right now inside cryptodev framework both rte_cryptodev_sym_session
  and driver specific session data are two completely different sctrucures
  (e.g. struct cryptodev_sym_session and struct null_crypto_session).
  Though current cryptodev implementation implicitly assumes that driver
  will allocate both of them from within the same mempool.
  Plus this is done in a manner that they override each other fields
  (reuse the same space - sort of implicit C union).
  That's probably not the best programming practice,
  plus make impossible to have readonly fields inside both of them.
  To overcome that situation propose to changed an API a bit, to allow
  to use two different mempools for these two distinct data structures.

 5. Add 'uint64_t userdata' inside struct rte_cryptodev_sym_session.
   I suppose that self-explanatory, and might be used in a lot of places
   (would be quite useful for ipsec library we develop).

The new proposed layout for rte_cryptodev_sym_session:
struct rte_cryptodev_sym_session {
        uint64_t userdata;
        /**< Can be used for external metadata */
        uint16_t nb_drivers;
        /**< number of elements in sess_data array */
        uint16_t priv_size;
        /**< session private data will be placed after sess_data */
        __extension__ struct {
                void *data;
                uint16_t refcnt;
        } sess_data[0];
        /**< Driver specific session material, variable size */

ipc: fix access after async request failure

Previous fix for rte_panic has moved setting of alarm before
sending the message. This means that whether we send a message,
the alarm would still trigger. The comment noted that cleanup
would happen in the alarm handler, but that's not what actually
happened - instead, in the event of failed send we freed the
memory in-place, before putting the request on the queue.

This works OK when the message is sent, but when sending the
message fails, the alarm would still trigger with a pointer
argument that points to non-existent memory, and cause
memory corruption.

There probably is a "proper" fix for this issue, with correct
handling of sent vs. unsent requests, however it would be
simpler just to sacrifice the sent request in the (extremely
unlikely) event of alarm set failing. The other process would
