2019-07-04i3c: master: Use struct_size() helperGustavo A. R. Silva
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(*defslvs) + ((ndevs - 1) * sizeof(struct i3c_ccc_dev_desc)) with: struct_size(defslvs, slaves, ndevs - 1) This code was detected with the help of Coccinelle.

2019-07-04iommu/arm-smmu-v3: Invalidate ATC when detaching a deviceJean-Philippe Brucker
We make the invalid assumption in arm_smmu_detach_dev() that the ATC is clear after calling pci_disable_ats(). For one thing, only enabling the PCIe ATS capability constitutes an implicit invalidation event, so the comment was wrong. More importantly, the ATS capability isn't necessarily disabled by pci_disable_ats() in a PF, if the associated VFs have ATS enabled. Explicitly invalidate all ATC entries in arm_smmu_detach_dev(). The endpoint cannot form new ATC entries because STE.EATS is clear.

2019-07-04gpio: stp-xway: improve module clock error handlingMartin Blumenstingl
Three module clock error handling improvements: - use devm_clk_get() so the clock instance can be freed if devm_gpiochip_add_data() fails later on - switch to clk_prepare_enable() so the driver is ready whenever the lantiq target switches to the common clock framework - disable the clock again (using clk_disable_unprepare()) if devm_gpiochip_add_data() All of these are virtually no-ops with the current lantiq target. However, these will be relevant if we switch to the common clock framework.

2019-07-03nfsd: allow forced expiration of NFSv4 clientsJ. Bruce Fields
NFSv4 clients are automatically expired and all their locks removed if they don't contact the server for a certain amount of time (the lease period, 90 seconds by default). There can still be situations where that's not enough, so allow userspace to force expiry by writing "expire\n" to the new nfsd/client/#/ctl file. (The generic "ctl" name is because I expect we may want to allow other operations on clients in the future.) The write will not return until the client is expired and all of its locks and other state removed. The fault injection code also provides a way of expiring clients, but it fails if there are any in-progress RPC's referencing the client. Also, its method of selecting a client to expire is a little more primitive--it uses an IP address, which can't always uniquely specify an NFSv4 client. Signed-off-by: J.

2019-07-03nfsd: escape high characters in binary dataJ. Bruce Fields
I'm exposing some information about NFS clients in pseudofiles. I expect to eventually have simple tools to help read those pseudofiles. But it's also helpful if the raw files are human-readable to the extent possible. It aids debugging and makes them usable on systems that don't have the latest nfs-utils. A minor challenge there is opaque client-generated protocol objects like state owners and client identifiers. Some clients generate those to include handy information in plain ascii. But they may also include arbitrary byte sequences. I think the simplest approach is to limit to isprint(c) && isascii(c) and escape everything else. That means you can just cat the file and get something that looks OK. Also, I'm trying to keep these files legal YAML, which requires them to UTF-8, and this is a simple way to guarantee that.
