Pull more xfs irix ioctl housecleaning from Darrick Wong: "Withdraw the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl definitions. This is the third and final of a series of small pull requests that perform some long overdue housecleaning of XFS ioctls. This time, we're withdrawing all variants of the ALLOCSP and FREESP ioctls from XFS' userspace API. This might be a little premature since we've only just removed the functionality, but as I pointed out in the last pull request, nobody (including fstests) noticed that it was broken for 20 years. In response to the patch, we received a single comment from someone who stated that they 'augment' the ioctl for their own purposes, but otherwise acquiesced to the withdrawal. I still want to try to clobber these old ioctl definitions in 5.17. So remove the header definitions for these ioctls. The just-removed implementation has allowed callers to read stale disk contents for more than **21 years** and nobody noticed or complained, which implies a lack of users aside from exploit programs" * tag 'xfs-5.17-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove the XFS_IOC_{ALLOC,FREE}SP* definitions

Pull xfs irix ioctl housecleaning from Darrick Wong: "Remove the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl families. This is the second of a series of small pull requests that perform some long overdue housecleaning of XFS ioctls. This time, we're vacating the implementation of all variants of the ALLOCSP and FREESP ioctls, which are holdovers from EFS in Irix, circa 1993. Roughly equivalent functionality have been available for both ioctls since 2.6.25 (April 2008): - XFS_IOC_FREESP ftruncates a file. - XFS_IOC_ALLOCSP is the equivalent of fallocate. As noted in the fix patch for CVE 2021-4155, the ALLOCSP ioctl has been serving up stale disk blocks since 2000, and in 21 years **nobody** noticed. On those grounds I think it's safe to vacate the implementation. Note that we lose the ability to preallocate and truncate relative to the current file position, but as nobody's ever implemented that for the VFS, I conclude that it's not in high demand. Linux has always used fallocate as the space management system call, whereas these Irix legacy ioctls only ever worked on XFS, and have been the cause of recent stale data disclosure vulnerabilities. As equivalent functionality is available elsewhere, remove the code" * tag 'xfs-5.17-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: kill the XFS_IOC_{ALLOC,FREE}SP* ioctls

MPJ ipv6 selftests currently lack per link route to the server net. Additionally, ipv6 subflows endpoints are created without any interface specified. The end-result is that in ipv6 self-tests subflows are created all on the same link, leading to expected delays and sporadic self-tests failures. Fix the issue by adding the missing setup bits.

2022-01-20parisc: Autodetect default output device and set console= kernel parameterHelge Deller1-0/+11
Usually palo (the PA-RISC boot loader) will check at boot time if the machine/firmware was configured to use the serial line (ttyS0, SERIAL_x) or the graphical display (tty0, graph) as default output device and add the correct "console=ttyS0" or "console=tty0" Linux kernel parameter to the kernel command line when starting the Linux kernel. But the kernel could also have been started via the HP-UX boot loader or directly in qemu, in which cases the console parameter is missing. This patch fixes this problem by adding the correct console= parameter if it's missing in the current kernel command line. Signed-off-by: Helge Deller <[email protected]>

2022-01-20of: Check 'of_node_reused' flag on of_match_device()Rob Herring1-1/+1
Commit 0f153a1b8193 ("usb: chipidea: Set the DT node on the child device") caused the child device to match on the parent driver instead of the child's driver since the child's DT node pointer matched. The worst case result is a loop of the parent driver probing another instance and creating yet another child device eventually exhausting the stack. If the child driver happens to match first, then everything works fine. A device sharing the DT node should never do DT based driver matching, so let's simply check of_node_reused in of_match_device() to prevent that.

The YAML DT encoding has leaked into some array properties. Properties which are defined as an array should have a schema that's just an array. That means there should only be a single level of 'minItems', 'maxItems', and/or 'items'.

Fix for failed to init adminq: -53 while VF is resetting via MAC address changing procedure. Added sync module to avoid reading deadbeef value in reinit adminq during software reset. Without this patch it is possible to trigger VF reset procedure during reinit adminq. This resulted in an incorrect reading of value from the AQP registers and generated the -53 error.

2022-01-20i40e: Fix issue when maximum queues is exceededJedrzej Jagielski3-13/+61
Before this patch VF interface vanished when maximum queue number was exceeded. Driver tried to add next queues even if there was not enough space. PF sent incorrect number of queues to the VF when there were not enough of them. Add an additional condition introduced to check available space in 'qp_pile' before proceeding. This condition makes it impossible to add queues if they number is greater than the number resulting from available space. Also add the search for free space in PF queue pair piles. Without this patch VF interfaces are not seen when available space for queues has been exceeded and following logs appears permanently in dmesg: "Unable to get VF config (-32)".

2022-01-20RISC-V: Do not use cpumask data structure for hartid bitmapAtish Patra11-136/+130
Currently, SBI APIs accept a hartmask that is generated from struct cpumask. Cpumask data structure can hold upto NR_CPUs value. Thus, it is not the correct data structure for hartids as it can be higher than NR_CPUs for platforms with sparse or discontguous hartids.

The spinwait method is only used for M-mode Linux or older firmwares without SBI HSM extension. For general Linux systems, ordered booting method is preferred anyways to support cpu hotplug and kexec. Make sure that __cpu_up_stack/task_pointer is only used for spinwait method.

2022-01-20RISC-V: Avoid using per cpu array for ordered bootingAtish Patra4-15/+58
Currently both order booting and spinwait approach uses a per cpu array to update stack & task pointer. This approach will not work for the following cases. 1. If NR_CPUs are configured to be less than highest hart id. 2. A platform has sparse hartid. This issue can be fixed for ordered booting as the booting cpu brings up one cpu at a time using SBI HSM extension which has opaque parameter that is unused until now. Introduce a common secondary boot data structure that can store the stack and task pointer. Secondary harts will use this data while booting up to setup the sp & tp.
