Misc driver patches for 5.15-rc1, second round
Here is a second round of misc driver patches for 5.15-rc1. In here is only updates for the Habanalabs driver. This request is late because the previously-objected-to dma-buf patches are all removed and some fixes that you and others found are now included in here as well. All of these have been in linux-next for well over a week with no reports of problems, and they are all self-contained to only this one driver. Full details are in the shortlog.

vduse: Introduce VDUSE - vDPA Device in Userspace
This VDUSE driver enables implementing software-emulated vDPA
devices in userspace. The vDPA device is created by
ioctl(VDUSE_CREATE_DEV) on /dev/vduse/control. Then a char device
interface (/dev/vduse/$NAME) is exported to userspace for device
emulation.
In order to make the device emulation more secure, the device's
control path is handled in kernel. A message mechnism is introduced
to forward some dataplane related control messages to userspace.
And in the data path, the DMA buffer will be mapped into userspace
address space through different ways depending on the vDPA bus to
which the vDPA device is attached. In virtio-vdpa case, the MMU-based
software IOTLB is used to achieve that. And in vhost-vdpa case, the
DMA buffer is reside in a userspace memory region which can be shared
to the VDUSE userspace processs via transferring the shmfd.
For more details on VDUSE design and usage, please see the follow-on
Documentation commit.

fq_codel: reject silly quantum parameters
syzbot found that forcing a big quantum attribute would crash hosts fast,
essentially using this:
tc qd replace dev eth0 root fq_codel quantum 4294967295
This is because fq_codel_dequeue() would have to loop
~2^31 times in :
if (flow->deficit <= 0) {
flow->deficit += q->quantum;
list_move_tail(&flow->flowchain, &q->old_flows);
goto begin;
}
SFQ max quantum is 2^19 (half a megabyte)
Lets adopt a max quantum of one megabyte for FQ_CODEL.

mm/mempolicy: add MPOL_PREFERRED_MANY for multiple preferred nodes
Patch series "Introduce multi-preference mempolicy", v7. This patch series introduces the concept of the MPOL_PREFERRED_MANY mempolicy. This mempolicy mode can be used with either the set_mempolicy(2) or mbind(2) interfaces. Like the MPOL_PREFERRED interface, it allows an application to set a preference for nodes which will fulfil memory allocation requests. Unlike the MPOL_PREFERRED mode, it takes a set of nodes. Like the MPOL_BIND interface, it works over a set of nodes. Unlike MPOL_BIND, it will not cause a SIGSEGV or invoke the OOM killer if those preferred nodes are not available. Along with these patches are patches for libnuma, numactl, numademo, and memhog. They still need some polish, but can be found here: https://gitlab.com/bwidawsk/numactl/-/tree/prefer-many It allows new usage: `numactl -P 0,3,4` The goal of the new mode is to enable some use-cases when using tiered memory usage models which I've lovingly named. 1a. The Hare - The interconnect is fast enough to meet bandwidth and latency requirements allowing preference to be given to all nodes with "fast" memory. 1b. The Indiscriminate Hare - An application knows it wants fast memory (or perhaps slow memory), but doesn't care which node it runs on. The application can prefer a set of nodes and then xpu bind to the local node (cpu, accelerator, etc). This reverses the nodes are chosen today where the kernel attempts to use local memory to the CPU whenever possible. This will attempt to use the local accelerator to the memory. 2. The Tortoise - The administrator (or the application itself) is aware it only needs slow memory, and so can prefer that. Much of this is almost achievable with the bind interface, but the bind interface suffers from an inability to fallback to another set of nodes if binding fails to all nodes in the nodemask. Like MPOL_BIND a nodemask is given. Inherently this removes ordering from the preference. > /* Set first two nodes as preferred in an 8 node system. */ > const unsigned long nodes = 0x3 > set_mempolicy(MPOL_PREFER_MANY, &nodes, 8); > /* Mimic interleave policy, but have fallback *. > const unsigned long nodes = 0xaa > set_mempolicy(MPOL_PREFER_MANY, &nodes, 8); Some internal discussion took place around the interface. There are two alternatives which we have discussed, plus one I stuck in: 1. Ordered list of nodes. Currently it's believed that the added complexity is nod needed for expected usecases. 2. A flag for bind to allow falling back to other nodes. This confuses the notion of binding and is less flexible than the current solution. 3. Create flags or new modes that helps with some ordering. This offers both a friendlier API as well as a solution for more customized usage. It's unknown if it's worth the complexity to support this. Here is sample code for how this might work: > // Prefer specific nodes for some something wacky > set_mempolicy(MPOL_PREFER_MANY, 0x17c, 1024); > > // Default > set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_SOCKET, NULL, 0); > // which is the same as > set_mempolicy(MPOL_DEFAULT, NULL, 0); > > // The Hare > set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, NULL, 0); > > // The Tortoise > set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE_REV, NULL, 0); > > // Prefer the fast memory of the first two sockets > set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, -1, 2); > This patch (of 5): The NUMA APIs currently allow passing in a "preferred node" as a single bit set in a nodemask. If more than one bit it set, bits after the first are ignored. This single node is generally OK for location-based NUMA where memory being allocated will eventually be operated on by a single CPU. However, in systems with multiple memory types, folks want to target a *type* of memory instead of a location. For instance, someone might want some high-bandwidth memory but do not care about the CPU next to which it is allocated. Or, they want a cheap, high capacity allocation and want to target all NUMA nodes which have persistent memory in volatile mode. In both of these cases, the application wants to target a *set* of nodes, but does not want strict MPOL_BIND behavior as that could lead to OOM killer or SIGSEGV. So add MPOL_PREFERRED_MANY policy to support the multiple preferred nodes requirement. This is not a pie-in-the-sky dream for an API. This was a response to a specific ask of more than one group at Intel. Specifically: 1. There are existing libraries that target memory types such as https://github.com/memkind/memkind. These are known to suffer from SIGSEGV's when memory is low on targeted memory "kinds" that span more than one node. The MCDRAM on a Xeon Phi in "Cluster on Die" mode is an example of this. 2. Volatile-use persistent memory users want to have a memory policy which is targeted at either "cheap and slow" (PMEM) or "expensive and fast" (DRAM). However, they do not want to experience allocation failures when the targeted type is unavailable. 3. Allocate-then-run. Generally, we let the process scheduler decide on which physical CPU to run a task. That location provides a default allocation policy, and memory availability is not generally considered when placing tasks. For situations where memory is valuable and constrained, some users want to allocate memory first, *then* allocate close compute resources to the allocation. This is the reverse of the normal (CPU) model. Accelerators such as GPUs that operate on core-mm-managed memory are interested in this model. A check is added in sanitize_mpol_flags() to not permit 'prefer_many' policy to be used for now, and will be removed in later patch after all implementations for 'prefer_many' are ready, as suggested by Michal Hocko.

"This is quite a small cycle, no major series stands out. The HNS and
rxe drivers saw the most activity this cycle, with rxe being broken
for a good chunk of time. The significant deleted line count is due to
a SPDX cleanup series.
Summary:
- Various cleanup and small features for rtrs
- kmap_local_page() conversions
- Driver updates and fixes for: efa, rxe, mlx5, hfi1, qed, hns
- Cache the IB subnet prefix
- Rework how CRC is calcuated in rxe
- Clean reference counting in iwpm's netlink
- Pull object allocation and lifecycle for user QPs to the uverbs

Pull exit cleanups from Eric Biederman: "In preparation of doing something about PTRACE_EVENT_EXIT I have started cleaning up various pieces of code related to do_exit. Most of that code I did not manage to get tested and reviewed before the merge window opened but a handful of very useful cleanups are ready to be merged. The first change is simply the removal of the bdflush system call. The code has now been disabled long enough that even the oldest userspace working userspace setups anyone can find to test are fine with the bdflush system call being removed. Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of calling do_exit directly is interesting only in that it is nearly the most difficult of the incorrect uses of do_exit to remove. The change to the seccomp code to simply send a signal instead of calling do_coredump directly is a very nice little cleanup made possible by realizing the existing signal sending helpers were missing a little bit of functionality that is easy to provide" * 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal/seccomp: Dump core when there is only one live thread signal/seccomp: Refactor seccomp signal and coredump generation signal/m68k: Use force_sigsegv(SIGSEGV) in fpsp040_die exit/bdflush: Remove the deprecated bdflush system call |

"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.

This tag contains habanalabs driver changes for v5.15:
- Add a new uAPI (under the cs ioctl) to enable to user to reserve signals and signal them from within its workloads, while the driver performs the waiting. This allows finer granularity of pipelining between the different engines and resource utilization. - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting on multiple command submissions (workloads) at the same time. This is an optimization for the user process so it won't need to call multiple times to the wait_for_cs ioctl. - Add new feature of "state dump", which can be triggered through new debugfs node. This is a similar concept to the kernel panic dump. This new mechanism retrieves information from the device in case one of the workloads that was sent by the user got stuck. This is very helpful for debugging the hang. - Add a new debugfs node to perform lookup of user pointers that are mapped to habana device's pmmu. - Fix to the tracking of user process when running inside a container. - Allow user to map more than 4GB of memory to the device MMU in single IOCTL call. - Minimize number of register reads done in GAUDI during user operation. - Allow user to retrieve the device's server type that the device is connected to. - Several fixes to the code of waiting on interrupts on behalf of the user. - Fixes and improvements to the hint mechanism in our VA allocation. - Update the firmware header files to the latest version while maintaining backward compatibility with older firmware versions. - Multiple fixes to various bugs. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE7TEboABC71LctBLFZR1NuKta54AFAmEvnt8ACgkQZR1NuKta 54B6GwgAgDZE/watviT5VzS/Cb5wXitOjLfq9eEOVqwD7+sT0c6PDSpIMiFnz4BV yCPttVAWJPgcQFde/6WXHz8kAsG1dMDQ6ClXHWwNyhxdjVuRAeoHjChlkoW3E0SW ZiSoWcQy6bCPmy0mfy6reZsJzO1IOokW0QpYVbQKbxaxS9TdVKhBIMWkALUPqQCz JfA2LEn4ZMbQIGdcm7gb5NI2xlBok94IKv3D5i9Isy3IyT1+yIYoncHZHDwBK6oV uhVvQK4it8i+wfEbxE1CHavPmXQXlvziIZNQ0TqlAOzncN4tc6a3mSdnJKcpinmS Gy93ceWgXxJDZbpTIXHB18lMg4z5yg== =I/ND -----END PGP SIGNATURE----- Merge tag 'misc-habanalabs-next-2021-09-01' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: This tag contains habanalabs driver changes for v5.15: - Add a new uAPI (under the cs ioctl) to enable to user to reserve signals and signal them from within its workloads, while the driver performs the waiting.

This is very helpful for debugging the hang. - Add a new debugfs node to perform lookup of user pointers that are mapped to habana device's pmmu. - Fix to the tracking of user process when running inside a container. - Allow user to map more than 4GB of memory to the device MMU in single IOCTL call. - Minimize number of register reads done in GAUDI during user operation. - Allow user to retrieve the device's server type that the device is connected to. - Several fixes to the code of waiting on interrupts on behalf of the user. - Fixes and improvements to the hint mechanism in our VA allocation. - Update the firmware header files to the latest version while maintaining backward compatibility with older firmware versions. - Multiple fixes to various bugs. * tag 'misc-habanalabs-next-2021-09-01' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (61 commits) habanalabs/gaudi: hwmon default card name habanalabs: add support for f/w reset habanalabs/gaudi: block ICACHE_BASE_ADDERESS_HIGH in TPC habanalabs: cannot sleep while holding spinlock habanalabs: never copy_from_user inside spinlock habanalabs: remove unnecessary device status check habanalabs: disable IRQ in user interrupts spinlock habanalabs: add "in device creation" status habanalabs/gaudi: invalidate PMMU mem cache on init habanalabs/gaudi: size should be printed in decimal habanalabs/gaudi: define DC POWER for secured PMC habanalabs/gaudi: unmask out of bounds SLM access interrupt habanalabs: add userptr_lookup node in debugfs habanalabs/gaudi: fetch TPC/MME ECC errors from F/W habanalabs: modify multi-CS to wait on stream masters habanalabs/gaudi: add monitored SOBs to state dump habanalabs/gaudi: restore user registers when context opens habanalabs/gaudi: increase boot fit timeout habanalabs: update to latest firmware headers habanalabs/gaudi: minimize number of register reads ... |

habanalabs: add "in device creation" status
On init, the disabled state is cleared right before hw_init and that causes the device to report on "Operational" state before the device initialization is finished. Although the char device is not yet exposed to the user at this stage, the sysfs entries are exposed. This can cause errors in monitoring applications that use the sysfs entries. In order to avoid this, a new state "in device creation" is introduced to ne reported when the device is not disabled but is still in init flow.

habanalabs: expose server type in INFO IOCTL
Add the server type property to the hl_info_hw_ip_info structure that is exposed to the user via the INFO IOCTL. This is needed by the userspace s/w stack to know the connections map of the internal links that connect the ASIC among themselves inside the server. The F/W will tell us, as part of the NIC information, the server type that the GAUDI is located in. Signed-off-by: Oded Gabbay <ogabbay@kernel.org> |

Pull move_mount updates from Christian Brauner:
"This contains an extension to the move_mount() syscall making it
possible to add a single private mount into an existing propagation
tree.
The use-case comes from the criu folks which have been struggling with
restoring complex mount trees for a long time. Variations of this work
have been discussed at Plumbers before, e.g.
https://www.linuxplumbersconf.org/event/7/contributions/640/
The extension to move_mount() enables criu to restore any set of mount
namespaces, mount trees and sharing group trees without introducing
yet more complexity into mount propagation itself.
The changes required to criu to make use of this and restore complex
propagation trees are available at
https://github.com/Snorch/criu/commits/mount-v2-poc
A cleaned-up version of this will go up for merging into the main criu
repo after this lands"

Pull btrfs updates from David Sterba:
"The highlights of this round are integrations with fs-verity and
idmapped mounts, the rest is usual mix of minor improvements, speedups
and cleanups.
There are some patches outside of btrfs, namely updating some VFS
interfaces, all straightforward and acked.
Features:
- fs-verity support, using standard ioctls, backward compatible with
read-only limitation on inodes with previously enabled fs-verity
- idmapped mount support
- make mount with rescue=ibadroots more tolerant to partially damaged
trees
- allow raid0 on a single device and raid10 on two devices,
degenerate cases but might be useful as an intermediate step during
conversion to other profiles
- zoned mode block group auto reclaim can be disabled via sysfs knob
Performance improvements:
- continue readahead of node siblings even if target node is in
memory, could speed up full send (on sample test +11%)
- batching of delayed items can speed up creating many files
- fsync/tree-log speedups
- avoid unnecessary work (gains +2% throughput, -2% run time on
sample load)
- reduced lock contention on renames (on dbench +4% throughput,
up to -30% latency)
Fixes:
- various zoned mode fixes
- preemptive flushing threshold tuning, avoid excessive work on
almost full filesystems
Core:
- continued subpage support, preparation for implementing remaining
features like compression and defragmentation; with some
limitations, write is now enabled on 64K page systems with 4K
sectors, still considered experimental
- no readahead on compressed reads
- inline extents disabled
- disabled raid56 profile conversion and mount
- improved flushing logic, fixing early ENOSPC on some workloads
- inode flags have been internally split to read-only and read-write
incompat bit parts, used by fs-verity
- new tree items for fs-verity
- descriptor item
- Merkle tree item
- inode operations extended to be namespace-aware
- cleanups and refactoring
Generic code changes:
- fs: new export filemap_fdatawrite_wbc
- fs: removed sync_inode
- block: bio_trim argument type fixups
- vfs: add namespace-aware lookup"

A reworked version of the opt-in L1D flush mechanism:
A stop gap for potential future speculation related hardware
vulnerabilities and a mechanism for truly security paranoid
applications.
It allows a task to request that the L1D cache is flushed when the kernel
switches to a different mm. This can be requested via prctl().
Changes vs. the previous versions:
- Get rid of the software flush fallback
- Make the handling consistent with other mitigations
- Kill the task when it ends up on a SMT enabled core which defeats the
purpose of L1D flushing obviously

Merge branch 'sg_nents' into rdma.git for-next
From Maor Gottlieb ==================== Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges. Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases. ==================== Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * 'sg_nents': RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append |
