Merge tag 'vfs-6.14-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull 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: samples/vfs: fix build warnings samples/vfs: use shared header samples/vfs/mountinfo: Use __u64 instead of uint64_t fs: remove useless lockdep assertion fs: use xarray for old mount id selftests: add listmount() iteration tests fs: cache first and last mount samples: add test-list-all-mounts selftests: remove unneeded include selftests: add tests for mntns iteration seltests: move nsfs into filesystems subfolder fs: simplify rwlock to spinlock fs: lockless mntns lookup for nsfs rculist: add list_bidir_{del,prev}_rcu() fs: lockless mntns rbtree lookup fs: add mount namespace to rbtree late fs: prepend statmount.mnt_opts string with security_sb_mnt_opts() mount: remove inlude/nospec.h include samples: add a mountinfo program to demonstrate statmount()/listmount() List of files: /linux/samples/vfs/.gitignore

bd32073632008979e39ab063acc252a5ce49efe9 - Merge patch series "fs: listmount()/statmount() fix and sample program"

Sun, 22 Dec 2024 11:22:18 +0100

Merge patch series "fs: listmount()/statmount() fix and sample program"Jeff Layton says:We had some recent queries internally asking how to use the newstatmount() and listmount() interfaces. I was doing some other work inthis area, so I whipped up this tool.My hope is that this will represent something of a "rosetta stone" forhow to translate between mountinfo and statmount(), and an example forother people looking to use the new interfaces.It may also be possible to use this as the basis for a listmount() andstatmount() testcase. We can call this program, and compare its outputto the mountinfo file.The second patch adds security mount options to the existing mnt_opts inthe statmount() interface, which I think is the final missing piecehere. The alternative to doing that would be to add a new string fieldfor that, but I'm not sure that's worthwhile.* patches from https://lore.kernel.org/r/20241115-statmount-v2-0-cd29aeff9cbb@kernel.org: fs: prepend statmount.mnt_opts string with security_sb_mnt_opts() samples: add a mountinfo program to demonstrate statmount()/listmount()Link: https://lore.kernel.org/r/20241115-statmount-v2-0-cd29aeff9cbb@kernel.orgSigned-off-by: Christian Brauner List of files: /linux/samples/vfs/.gitignore

c6640d46dc5a31ee7363545530836c10b9ddb9de - samples: add a mountinfo program to demonstrate statmount()/listmount()

Fri, 15 Nov 2024 16:35:52 +0100

samples: add a mountinfo program to demonstrate statmount()/listmount()Add a new "mountinfo" sample userland program that demonstrates how touse statmount() and listmount() to get at the same info that/proc/pid/mountinfo provides.The output of the program tries to mimic the mountinfo procfilecontents. With the -p flag, it can be pointed at an arbitrary pid toprint out info about its mount namespace. With the -r flag it willattempt to walk all of the namespaces under the pid's mount namespaceand dump out mount info from all of them.Signed-off-by: Jeff Layton Link: https://lore.kernel.org/r/20241115-statmount-v2-1-cd29aeff9cbb@kernel.orgSigned-off-by: Christian Brauner List of files: /linux/samples/vfs/.gitignore
