2017-02-02staging: unisys: visornic: prevent hang doing 'modprobe -r visornic'Tim Sell
A stray+extraneous 'netif_napi_add()' that we were doing in visornic_probe() was causing havoc when we got into visornic_remove(), called during 'modprobe -r visornic'. The symptom was a processor busy-wait loop on the modprobe process, which '/proc/<pid>/stack' would show looping doing napi things. Presumably the stray line got there as a result of some merging snafoo, and has been deleted to fix the problem. With this patch 'modprobe -r visornic' and a subsequent 'modprobe visornic' both complete successfully, and result in an operational network.

These redundant unlocks of visornic_devdata.priv_lock would result in the RHEL 7.2 guests hanging during service partition recovery testing. __Testing__ * An scp of a large file was started from a remote host TO the RHEL 7.2 Linux guest. * During the scp transfer, s-Par service partition recovery was forced twice. After each occasion, I verified that the guest recovered completely (all s-Par guest devices), and that the file transfer resumed. * Within the RHEL 7.2 guest environment, copied the large file to another location in the local filesystem. * During the copy, s-Par service partition recovery was again forced twice. After each occasion, I verified that the guest recovered completely (all s-Par guest devices), and that the copy resumed. * An scp of the new copy of the large file was started FROM the RHEL 7.2 guest to a remote host. * During the scp transfer, s-Par service partition recovery was forced twice. After each occasion, I verified that the guest recovered completely (all s-Par guest devices), and that the file transfer resumed. * Used cmp to verify that the large file had successfully survived the round-trip without becoming corrupted.

2016-04-28staging: unisys: visornic: convert BUG_ON to dev_err() messageTim Sell
The caller of visor_copy_fragsinfo_from_skb() is prepared to log a dev_err() message if it fails (by returning a negative value), so we now just fail in the one occasion where visor_copy_fragsinfo_from_skb() was doing a BUG_ON. There was also a problem before where visor_copy_fragsinfo_from_skb() was returning a negative to indicate error, yet it was declared to return an unsigned value! So obviously that needed correcting too.

2016-04-11staging: unisys: visornic: prevent double-unlock of priv_lockTim Sell
Previously, devdata->priv_lock was being unlocked in visornic_serverdown() both before calling visornic_serverdown_complete(), then again at the end of the function. This bug was corrected. The structure of visornic_serverdown() was also improved to make it easier to follow and to decrease the chance that such bugs will be introduced again. The main-path logic now falls thru down the left-side of the page, with a common error-exit point to handle error conditions.
