* net: hns3: fix to stop multiple HNS reset due to the AER changesShiju Jose2019-03-103-3/+11
| | | | | | | | | | | | | | | | | | | | | | | The commit bfcb79fca19d ("PCI/ERR: Run error recovery callbacks for all affected devices") affected the non-fatal error recovery logic for the HNS and RDMA devices. This is because each HNS PF under PCIe bus receive callbacks from the AER driver when an error is reported for one of the PF. This causes unwanted PF resets because the HNS decides which PF to reset based on the reset type set. The HNS error handling code sets the reset type based on the hw error type detected. This patch provides fix for the above issue for the recovery of the hw errors in the HNS and RDMA devices.

| | | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(struct boo) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

|\| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.
