            Bug ID: 105
           Summary: Cannot create crypto_openssl after vdev_uninit
           Product: DPDK
           Version: 18.08
          Hardware: x86
                OS: Linux
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: cryptodev
          Assignee: dev@dpdk.org
          Reporter: sunnylandh@gmail.com
  Target Milestone: ---

Overview:
If any created crypto_openssl device has been uninitialized, new crypto_openssl
device cannot be created.

Steps to Reproduce:

1) Compile this snippet with command line:
gcc -m64 -O3 -march=native -o x x.c -I/usr/local/include/dpdk -ldpdk

```
#include <inttypes.h>
#include <stdio.h>

#include <rte_config.h>

#include <rte_bus_vdev.h>
#include <rte_eal.h>
#include <rte_errno.h>

#define WANT_UNINIT

int main(int argc, char** argv) {
  int res = rte_eal_init(argc, argv);
  if (res < 0) {
    printf("rte_eal_init(argc, argv) %d\n", rte_errno);
    return 3;
  }

  res = rte_vdev_init("crypto_openssl_0", "");
  if (res != 0) {
    printf("rte_vdev_init(\"crypto_openssl_0\", \"\") %d\n", res);
    return 4;
  }

#ifdef WANT_UNINIT
  res = rte_vdev_uninit("crypto_openssl_0");
  if (res != 0) {
    printf("rte_vdev_uninit(\"crypto_openssl_0\") %d\n", res);
    return 5;
  }
#endif // WANT_UNINIT

  res = rte_vdev_init("crypto_openssl_1", "");
  if (res != 0) {
    printf("rte_vdev_init(\"crypto_openssl_1\", \"\") %d\n", res);
    return 6;
  }

  printf("OK\n");
  return 0;
}
```

2) Execute the program with this command line:
sudo ./x -d /usr/local/lib/librte_pmd_openssl.so

Actual Results:
The program fails to create "crypto_openssl_1" device, and prints the following
log output:

```
EAL: Detected 24 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Probing VFIO support...
CRYPTODEV: [crypto_openssl] - Creating cryptodev crypto_openssl_0

CRYPTODEV: [crypto_openssl] - Initialisation parameters - name:
crypto_openssl_0,socket id: 0, max queue pairs: 8
CRYPTODEV: [crypto_openssl] Closing crypto device crypto_openssl_0
CRYPTODEV: [crypto_openssl] - Creating cryptodev crypto_openssl_1

CRYPTODEV: [crypto_openssl] - Initialisation parameters - name:
crypto_openssl_1,socket id: 0, max queue pairs: 8
CRYPTODEV: rte_cryptodev_pmd_create() line 113: [crypto_openssl] Failed to
allocate crypto device for crypto_openssl_1
cryptodev_openssl_create() line 2102: failed to create cryptodev vdev
cryptodev_openssl_create() line 2129: driver : create failed
rte_vdev_init("crypto_openssl_1", "") -14
```

Expected Results:
The program successfully creates crypto_openssl_1 device, and prints "OK".

Build Date & Hardware:
DPDK release 18.08 installed from tarball.
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz

Additional Builds and Platforms: not tested.

Additional Information:
The program completes successfully if commenting out `#define WANT_UNINIT`
line.
