ixgbe: fix memory leak on ipsec allocation

2018-06-20T19:01:41Z

[ Upstream commit c89ebb968f04c71e16e86c91caeacb045dc8f908 ] The error clean up path kfree's adapter->ipsec and should be instead kfree'ing ipsec. Fix this. Also, the err1 error exit path does not need to kfree ipsec because this failure path was for the failed allocation of ipsec.

qede: Fix gfp flags sent to rdma event node allocation

net: aquantia: fix unsigned numvecs comparison with less than zero

2018-06-20T19:01:39Z

commit 58d813afbe89658a5972747460a5fe19dec4dbcb upstream. This was originally mistakenly submitted to net-next. Resubmitting to net. The comparison of numvecs < 0 is always false because numvecs is a u32 and hence the error return from a failed call to pci_alloc_irq_vectores is never detected. Fix this by using the signed int ret to handle the error return and assign numvecs to err.

net: aquantia: Limit number of vectors to actually allocated irqs

2018-06-20T19:01:38Z

[ Upstream commit a09bd81b5413d1b4d705c6c5303b5d311069da22 ] Driver should use pci_alloc_irq_vectors return value to correct number of allocated vectors and napi instances. Otherwise it'll panic later in pci_irq_vector. Driver also should allow more than one MSI vectors to be allocated. Error return path from pci_alloc_irq_vectors is also fixed to revert resources in a correct sequence when error happens.
