Even if a device failed to plug, it's still a device
object that references the devargs. Those devargs will
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.

so they doesn't need to be freed. Then free the

Consider the following scenario:
1) primary process (A) starts, probes the bus
2) a secondary process (B) starts, probes the bus
3) yet another secondary process (C) starts
4) (C) registers the pci driver and hotplugs the device
* an IPC attach req is sent to the primary (A)
* (A) ignores the -EEXIST from process-local probe
* (A) propagates the request to all secondary processes
* (B) responds with -EEXIST
* (A) replies to the original request with the -EEXIST
return code
* the -EEXIST is returned back to the user, although the
device was successfully attached both locally and in
all other processes
This patch makes the primary process reply with rc=0 even if
there was another secondary process with the device already
attached. The primary process already didn't reply with -EEXIST
when the device was attached locally, so now this behavior is
even more consistent. Looking by the code, this seems to be the
originally intended behavior.

When primary process receives an IPC attach request
of a device that's already locally-attached, it
doesn't setup its variables properly and is prone to
segfaulting on a subsequent rollback.
`ret = local_dev_probe(req->devargs, &dev)`
The above function will set `dev` pointer to the
proper device *unless* it returns with error. One of
those errors is -EEXIST, which the hotplug function
explicitly ignores. For -EEXIST, it proceeds with
attaching the device and expects the dev pointer to
be valid.
This patch makes `local_dev_probe` set the dev pointer
even if it returns -EEXIST.

detach, which could also theoretically segfault on

Setting up a device that wasn't setup in the primary
process will possibly break the primary process. That's
because the IPC message to retrieve the group fd in the
primary will also *open* that group if it wasn't opened
before. Even though the secondary process closes that fd
soon after as a part of its error handling path, the
primary process leaks it.
What's worse, opening that fd on the primary will
increment the process-local counter of opened groups.
If it was 0 before, then the group will never be added
to the vfio container, nor dpdk memory will be ever
mapped.
This patch moves the proper error checks earlier in the
code to fully prevent setting up devices in secondary
processes that weren't setup in the primary process.

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 */
};

Currently, the most complete (but still incomplete) user guide for
EAL command-line parameters resides in user guide for testpmd.
This is wrong on multiple levels, and should not be the case.
To fix it, we have to create a document that lists all supported
EAL command-line arguments. However, because different platforms
support different subsets of available EAL parameters, instead of
creating a single file, we will create a common file in
doc/guides/common containing documentation for EAL parameters
that are supported on all of our supported platforms (Linux and
FreeBSD at the time of this writing).
We will then include this document in the Getting Started guides
for all supported platforms, so that any changes made to
documentation for commonly supported EAL parameters will be
reflected in Getting Started guides for all platforms.
This patch also removes EAL parameters documentation from the
testpmd user guide, and instead adds references to the newly
created documents in both testpmd user guides and in sample
applications guide.
