2018-12-10Revert "fscrypt: add Speck128/256 support"Alistair Strachan
This reverts commit eb13e0b69296ad1d3a9a3fa0cb6570aaf99f9f0c. Resolves conflicts with a later CL, e7724207f71e "fscrypt: log the crypto algorithm implementations". Also leaves the include/uapi/linux/fs.h constants in place to prevent future accidental re-use.

Since commit a60d64b15c20 ("media: lirc: lirc interface should not be a raw decoder"), the message in the documentation is incorrect as the module name is rc_core, not lirc_dev. Since the message is not useful, just make the message debug and remove it from the documentation.

2018-12-10UPSTREAM: media: lirc: when transmitting scancodes, block until transmit is doneSean Young
The semantics for lirc IR transmit with raw IR is that the write call should block until the IR is transmitted. Some drivers have no idea when this actually is (e.g. mceusb), so there is a wait. This is useful for userspace, as it might want to send a IR button press, a gap of a predefined number of milliseconds, and then send a repeat message. It turns out that for transmitting scancodes this feature is even more useful, as user space has no idea how long the IR is. So, maintain the existing semantics for IR scancode transmit.

2018-12-10UPSTREAM: [media] rc: change wakeup_protocols to list all protocol variantsSean Young
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

2018-12-01namei: allow restricted O_CREAT of FIFOs and regular filesSalvatore Mesoraca
commit 30aba6656f61ed44cba445a3c0d38b296fa9e8f5 upstream. Disallows open of FIFOs or regular files not owned by the user in world writable sticky directories, unless the owner is the same as that of the directory or the file is opened without the O_CREAT flag. The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.

2018-10-29f2fs: checkpoint disablingDaniel Rosenberg
Note that, it requires "f2fs: return correct errno in f2fs_gc". This adds a lightweight non-persistent snapshotting scheme to f2fs. To use, mount with the option checkpoint=disable, and to return to normal operation, remount with checkpoint=enable. If the filesystem is shut down before remounting with checkpoint=enable, it will revert back to its apparent state when it was first mounted with checkpoint=disable. This is useful for situations where you wish to be able to roll back the state of the disk in case of some critical failure.
