2017-07-12random: do not ignore early device randomnessKees Cook1-0/+5
The add_device_randomness() function would ignore incoming bytes if the crng wasn't ready. This additionally makes sure to make an early enough call to add_latent_entropy() to influence the initial stack canary, which is especially important on non-x86 systems where it stays the same through the life of the boot.

2017-07-08bonding: avoid NETDEV_CHANGEMTU event when unregistering slaveWANG Cong1-6/+9
As Hongjun/Nicolas summarized in their original patch: " When a device changes from one netns to another, it's first unregistered, then the netns reference is updated and the dev is registered in the new netns. Thus, when a slave moves to another netns, it is first unregistered. This triggers a NETDEV_UNREGISTER event which is caught by the bonding driver. The driver calls bond_release(), which calls dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in the old netns). " This is a very special case, because the device is being unregistered no one should still care about the NETDEV_CHANGEMTU event triggered at this point, we can avoid broadcasting this event on this path, and avoid touching inetdev_event()/addrconf_notify() path. It requires to export __dev_set_mtu() to bonding driver.

Pull Writeback error handling updates from Jeff Layton: "This pile represents the bulk of the writeback error handling fixes that I have for this cycle. Some of the earlier patches in this pile may look trivial but they are prerequisites for later patches in the series. The aim of this set is to improve how we track and report writeback errors to userland. Most applications that care about data integrity will periodically call fsync/fdatasync/msync to ensure that their writes have made it to the backing store. For a very long time, we have tracked writeback errors using two flags in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a writeback error occurs (via mapping_set_error) and are cleared as a side-effect of filemap_check_errors (as you noted yesterday). This model really sucks for userland. Only the first task to call fsync (or msync or fdatasync) will see the error. Any subsequent task calling fsync on a file will get back 0 (unless another writeback error occurs in the interim). If I have several tasks writing to a file and calling fsync to ensure that their writes got stored, then I need to have them coordinate with one another. That's difficult enough, but in a world of containerized setups that coordination may even not be possible. But wait...it gets worse! The calls to filemap_check_errors can be buried pretty far down in the call stack, and there are internal callers of filemap_write_and_wait and the like that also end up clearing those errors. Many of those callers ignore the error return from that function or return it to userland at nonsensical times (e.g. truncate() or stat()). If I get back -EIO on a truncate, there is no reason to think that it was because some previous writeback failed, and a subsequent fsync() will (incorrectly) return 0. This pile aims to do three things: 1) ensure that when a writeback error occurs that that error will be reported to userland on a subsequent fsync/fdatasync/msync call, regardless of what internal callers are doing 2) report writeback errors on all file descriptions that were open at the time that the error occurred. This is a user-visible change, but I think most applications are written to assume this behavior anyway. Those that aren't are unlikely to be hurt by it. 3) document what filesystems should do when there is a writeback error. Today, there is very little consistency between them, and a lot of cargo-cult copying. We need to make it very clear what filesystems should do in this situation. To achieve this, the set adds a new data type (errseq_t) and then builds new writeback error tracking infrastructure around that. Once all of that is in place, we change the filesystems to use the new infrastructure for reporting wb errors to userland. Note that this is just the initial foray into cleaning up this mess. There is a lot of work remaining here: 1) convert the rest of the filesystems in a similar fashion. Once the initial set is in, then I think most other fs' will be fairly simple to convert. Hopefully most of those can in via individual filesystem trees. 2) convert internal waiters on writeback to use errseq_t for detecting errors instead of relying on the AS_* flags. I have some draft patches for this for ext4, but they are not quite ready for prime time yet. This was a discussion topic this year at LSF/MM too.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.13 series. Some administrativa: I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO driver coming in through this tree, along with a whole bunch of Exar 8250 fixes. These are ACKed by Greg and also hit drivers/platform/* where they are ACKed by Andy Shevchenko. Speaking about drivers/platform/* there is also a bunch of ACPI stuff coming through that route, again ACKed by Andy. The MCP23S08 changes are coming in here as well. You already have the commits in your tree, so this is just a result of sharing an immutable branch between pin control and GPIO. Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage.
