Subject: [PATCH] qdevice: Destroy non blocking client on failure
|
|
|
943740 |
|
|
|
943740 |
This fixes regression introduced in patch
|
|
|
943740 |
8217e33e86bca79dc307e112f0c0c4a278f9a568 which made qdevice assert when
|
|
|
943740 |
PR_GetError in nss_sock_non_blocking_client_try_next called by
|
|
|
943740 |
qdevice_model_net_pre_poll_loop returns error other than
|
|
|
943740 |
PR_IN_PROGRESS_ERROR. This is usually not happening - only way to get
|
|
|
943740 |
such error seems to be to ifdown ALL network interfaces other than
|
|
|
943740 |
loopback and returned error is then PR_NETWORK_UNREACHABLE_ERROR
|
|
|
943740 |
(-5980).
|
|
|
943740 |
|
|
|
943740 |
Fix is rather simple (and present in pre
|
|
|
943740 |
8217e33e86bca79dc307e112f0c0c4a278f9a568) - just call
|
|
|
943740 |
nss_sock_non_blocking_client_destroy.
