Pull vfs mount updates from Christian Brauner:
- Add a mountinfo program to demonstrate statmount()/listmount()
Add a new "mountinfo" sample userland program that demonstrates how
to use statmount() and listmount() to get at the same info that
/proc/pid/mountinfo provides
- Remove pointless nospec.h include
- Prepend statmount.mnt_opts string with security_sb_mnt_opts()
Currently these mount options aren't accessible via statmount()
- Add new mount namespaces to mount namespace rbtree outside of the
namespace semaphore
- Lockless mount namespace lookup
Currently we take the read lock when looking for a mount namespace to
list mounts in. We can make this lockless. The simple search case can
just use a sequence counter to detect concurrent changes to the
rbtree
For walking the list of mount namespaces sequentially via nsfs we
keep a separate rcu list as rb_prev() and rb_next() aren't usable
safely with rcu. Currently there is no primitive for retrieving the
previous list member. To do this we need a new deletion primitive
that doesn't poison the prev pointer and a corresponding retrieval
helper
Since creating mount namespaces is a relatively rare event compared
with querying mounts in a foreign mount namespace this is worth it.
Once libmount and systemd pick up this mechanism to list mounts in
foreign mount namespaces this will be used very frequently
- Add extended selftests for lockless mount namespace iteration
- Add a sample program to list all mounts on the system, i.e., in
all mount namespaces
- Improve mount namespace iteration performance
Make finding the last or first mount to start iterating the mount
namespace from an O(1) operation and add selftests for iterating the
mount table starting from the first and last mount
- Use an xarray for the old mount id
While the ida does use the xarray internally we can use it explicitly
which allows us to increment the unique mount id under the xa lock.
This allows us to remove the atomic as we're now allocating both ids
in one go
- Use a shared header for vfs sample programs
- Fix build warnings for new sample program to list all mounts
* tag 'vfs-6.14-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:

For a long time the default value has been 65535 and during the pidfd dicussions Linus proposed to bump pid_max by default. Based on this discussion systemd started bumping pid_max to 2^22. So all new systems now run with a very high pid_max limit with some distros having also backported that change. The decision to bump pid_max is obviously correct. It just doesn't make a lot of sense nowadays to enforce such a low pid number. There's sufficient tooling to make selecting specific processes without typing really large pid numbers available. In any case, there are workloads that have expections about how large pid numbers they accept. Either for historical reasons or architectural reasons. One concreate example is the 32-bit version of Android's bionic libc which requires pid numbers less than 65536. There are workloads where it is run in a 32-bit container on a 64-bit kernel. If the host has a pid_max value greater than 65535 the libc will abort thread creation because of size assumptions of pthread_mutex_t. That's a fairly specific use-case however, in general specific workloads that are moved into containers running on a host with a new kernel and a new systemd can run into issues with large pid_max values. Obviously making assumptions about the size of the allocated pid is suboptimal but we have userspace that does it. Of course, giving containers the ability to restrict the number of processes in their respective pid namespace indepent of the global limit through pid_max is something desirable in itself and comes in handy in general. Independent of motivating use-cases the existence of pid namespaces makes this also a good semantical extension and there have been prior proposals pushing in a similar direction. The trick here is to minimize the risk of regressions which I think is doable. The fact that pid namespaces are hierarchical will help us here. What we mostly care about is that when the host sets a low pid_max limit, say (crazy number) 100 that no descendant pid namespace can allocate a higher pid number in its namespace. Since pid allocation is hierarchial this can be ensured by checking each pid allocation against the pid namespace's pid_max limit. This means if the allocation in the descendant pid namespace succeeds, the ancestor pid namespace can reject it. If the ancestor pid namespace has a higher limit than the descendant pid namespace the descendant pid namespace will reject the pid allocation. The ancestor pid namespace will obviously not care about this. All in all this means pid_max continues to enforce a system wide limit on the number of processes but allows pid namespaces sufficient leeway in handling workloads with assumptions about pid values and allows containers to restrict the number of processes in a pid namespace through the pid_max interface" * tag 'kernel-6.14-rc1.pid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: tests/pid_namespace: add pid_max tests pid: allow pid_max to be set per pid namespace |

A crucical step in the patch series is how to go from inode number to struct pid without leaking information into unprivileged contexts. The issue is that in order to find a struct pid the pid number in the initial pid namespace must be encoded into the file handle via name_to_handle_at(2). This can be used by containers using a separate pid namespace to learn what the pid number of a given process in the initial pid namespace is. While this is a weak information leak it could be used in various exploits and in general is an ugly wart in the design. To solve this problem a new way is needed to lookup a struct pid based on the inode number allocated for that struct pid. The other part is to remove the custom inode number allocation on 32bit systems that is also an ugly wart that should go away. Allocate unique identifiers for struct pid by simply incrementing a 64 bit counter and insert each struct pid into the rbtree so it can be looked up to decode file handles avoiding to leak actual pids across pid namespaces in file handles. On both 64 bit and 32 bit the same 64 bit identifier is used to lookup struct pid in the rbtree. On 64 bit the unique identifier for struct pid simply becomes the inode number. Comparing two pidfds continues to be as simple as comparing inode numbers. On 32 bit the 64 bit number assigned to struct pid is split into two 32 bit numbers. The lower 32 bits are used as the inode number and the upper 32 bits are used as the inode generation number. Whenever a wraparound happens on 32 bit the 64 bit number will be incremented by 2 so inode numbering starts at 2 again. When a wraparound happens on 32 bit multiple pidfds with the same inode number are likely to exist. This isn't a problem since before pidfs pidfds used the anonymous inode meaning all pidfds had the same inode number. On 32 bit sserspace can thus reconstruct the 64 bit identifier by retrieving both the inode number and the inode generation number to compare, or use file handles. This gives the same guarantees on both 32 bit and 64 bit. - Implement file handle support This is based on custom export operation methods which allows pidfs to implement permission checking and opening of pidfs file handles cleanly without hacking around in the core file handle code too much. - Support bind-mounts Allow bind-mounting pidfds. Similar to nsfs let's allow bind-mounts for pidfds. This allows pidfds to be safely recovered and checked for process recycling. Instead of checking d_ops for both nsfs and pidfs we could in a follow-up patch add a flag argument to struct dentry_operations that functions similar to file_operations->fop_flags. * tag 'vfs-6.14-rc1.pidfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests: add pidfd bind-mount tests pidfs: allow bind-mounts pidfs: lookup pid through rbtree selftests/pidfd: add pidfs file handle selftests pidfs: check for valid ioctl commands pidfs: implement file handle support exportfs: add permission method fhandle: pull CAP_DAC_READ_SEARCH check into may_decode_fh() exportfs: add open method fhandle: simplify error handling pseudofs: add support for export_ops pidfs: support FS_IOC_GETVERSION pidfs: remove 32bit inode number handling pidfs: rework inode number allocation |

Pull misc vfs updates from Christian Brauner:
"Features:
- Support caching symlink lengths in inodes
The size is stored in a new union utilizing the same space as
i_devices, thus avoiding growing the struct or taking up any more
space
When utilized it dodges strlen() in vfs_readlink(), giving about
1.5% speed up when issuing readlink on /initrd.img on ext4
- Add RWF_DONTCACHE iocb and FOP_DONTCACHE file_operations flag
If a file system supports uncached buffered IO, it may set
FOP_DONTCACHE and enable support for RWF_DONTCACHE.
If RWF_DONTCACHE is attempted without the file system supporting
it, it'll get errored with -EOPNOTSUPP
- Enable VBOXGUEST and VBOXSF_FS on ARM64
Now that VirtualBox is able to run as a host on arm64 (e.g. the
Apple M3 processors) we can enable VBOXSF_FS (and in turn
VBOXGUEST) for this architecture.
Tested with various runs of bonnie++ and dbench on an Apple MacBook
Pro with the latest Virtualbox 7.1.4 r165100 installed
Cleanups:
- Delay sysctl_nr_open check in expand_files()
- Use kernel-doc includes in fiemap docbook
- Use page->private instead of page->index in watch_queue
- Use a consume fence in mnt_idmap() as it's heavily used in
link_path_walk()
- Replace magic number 7 with ARRAY_SIZE() in fc_log
- Sort out a stale comment about races between fd alloc and dup2()
- Fix return type of do_mount() from long to int
- Various cosmetic cleanups for the lockref code

latter has reached the closed status, the msk socket will report an
error to the user-space, as per protocol specification, causing the

tools: fix atomic_set() definition to set the value correctly
Currently vma test is failing because of the new vma_assert_attached()
assertion. The check is failing because previous refcount_set() inside
vma_mark_attached() is a NoOp. Fix the definition of atomic_set() to
correctly set the value of the atomic.

kselftest/arm64: Add 2024 dpISA extensions to hwcap test
Add coverage of the hwcaps for the 2024 dpISA extensions to the hwcap test. We don't actually test SIGILL generation for CMPBR since the need to branch makes it a pain to generate and the SIGILL detection would be unreliable anyway. Since this should be very unusual we provide a stub function rather than supporting a missing test. The sigill functions aren't well sorted in the file so the ordering is a bit random.

selftests: tc-testing: reduce rshift value
After previous change rshift >= 32 is no longer allowed. Modify the test to use 31, the test doesn't seem to send any traffic so the exact value shouldn't matter.

Nothing major here. Over the last two weeks we gathered only around
two-thirds of our normal weekly fix count, but delaying sending these
until -rc7 seemed like a really bad idea.
AFAIK we have no bugs under investigation. One or two reverts for
stuff for which we haven't gotten a proper fix will likely come in
the next PR.
Including fixes from wireles and netfilter.
Current release - fix to a fix:
- netfilter: nft_set_hash: unaligned atomic read on struct nft_set_ext
- eth: gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeup
Previous releases - regressions:
- net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets
- mptcp:
- fix sleeping rcvmsg sleeping forever after bad recvbuffer adjust
- fix TCP options overflow
- prevent excessive coalescing on receive, fix throughput
- net: fix memory leak in tcp_conn_request() if map insertion fails
- wifi: cw1200: fix potential NULL dereference after conversion
to GPIO descriptors
- phy: micrel: dynamically control external clock of KSZ PHY,
fix suspend behavior
Previous releases - always broken:
- af_packet: fix VLAN handling with MSG_PEEK
- net: restrict SO_REUSEPORT to inet sockets
- netdev-genl: avoid empty messages in NAPI get
- dsa: microchip: fix set_ageing_time function on KSZ9477 and LAN937X
- eth: gve: XDP fixes around transmit, queue wakeup etc.
- eth: ti: icssg-prueth: fix firmware load sequence to prevent time
jump which breaks timesync related operations
