... lest we get livelocks between path_is_under() and d_path() and friends. The thing is, wrt fairness lglocks are more similar to rwsems than to rwlocks; it is possible to have thread B spin on attempt to take lock shared while thread A is already holding it shared, if B is on lower-numbered CPU than A and there's a thread C spinning on attempt to take the same lock exclusive. As the result, we need consistent ordering between vfsmount_lock (lglock) and rename_lock (seq_lock), even though everything that takes both is going to take vfsmount_lock only shared.

For 82576 MAC type, max_adj is reported as 1000000000 ppb. However, if this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping the PHC (instead of going at twice the nominal speed). Fix the advertised max_adj value to the largest value hardware can handle. As there is no min_adj value available (-max_adj is used instead), this will also prevent stopping the clock intentionally. It's probably not a big deal, other igb MAC types don't support stopping the clock, either.

The max_vfs= option has always been self limiting to the number of VFs supported by the device. fa44f2f1 added SR-IOV configuration via sysfs, but in the process broke this self correction factor. The failing path is: igb_probe igb_sw_init if (max_vfs > 7) { adapter->vfs_allocated_count = 7; ... igb_probe_vfs igb_enable_sriov(, max_vfs) if (num_vfs > 7) { err = -EPERM; ... This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out when igb_probe finally calls igb_reset. It seems like a really bad idea, and somewhat pointless, to set vfs_allocated_count separate from vf_data, but limiting max_vfs is enough to avoid the null pointer.

When the ixgbevf driver is opened the request to allocate MSIX irq vectors may fail. In that case the driver will call ixgbevf_down() which will call ixgbevf_irq_disable() to clear the HW interrupt registers and calls synchronize_irq() using the msix_entries pointer in the adapter structure. However, when the function to request the MSIX irq vectors failed it had already freed the msix_entries which causes an OOPs from using the NULL pointer in synchronize_irq(). The calls to pci_disable_msix() and to free the msix_entries memory should not occur if device open fails. Instead they should be called during device driver removal to balance with the call to pci_enable_msix() and the call to allocate msix_entries memory during the device probe and driver load.

As reported by Jan, and others over the past few years, there is a race condition caused by unix_release setting the sock->sk pointer to NULL before properly marking the socket as dead/orphaned. This can cause a problem with the LSM hook security_unix_may_send() if there is another socket attempting to write to this partially released socket in between when sock->sk is set to NULL and it is marked as dead/orphaned. This patch fixes this by only setting sock->sk to NULL after the socket has been marked as dead; I also take the opportunity to make unix_release_sock() a void function as it only ever returned 0/success. Dave, I think this one should go on the -stable pile. Special thanks to Jan for coming up with a reproducer for this problem.
