448fa701 - sysv: Remove the filesystem

Thu, 20 Feb 2025 16:39:41 +0000

sysv: Remove the filesystemSince 2002 (change "Replace BKL for chain locking with sysvfs-privaterwlock") the sysv filesystem was doing IO under a rwlock in itsget_block() function (yes, a non-sleepable lock hold over a functionused to read inode metadata for all reads and writes). Nobody noticeduntil syzbot in 2023 [1]. This shows nobody is using the filesystem.Just drop it.[1] https://lore.kernel.org/all/0000000000000ccf9a05ee84f5b0@google.com/Signed-off-by: Jan Kara Link: https://lore.kernel.org/r/20250220163940.10155-2-jack@suse.czReviewed-by: Jeff Layton Reviewed-by: "Darrick J.

d08e2045 - bpf: introduce new VFS based BPF kfuncs

Wed, 31 Jul 2024 11:08:31 +0000

bpf: introduce new VFS based BPF kfuncsAdd a new variant of bpf_d_path() named bpf_path_d_path() which takesthe form of a BPF kfunc and enforces KF_TRUSTED_ARGS semantics ontoits arguments.This new d_path() based BPF kfunc variant is intended to address thelegacy bpf_d_path() BPF helper's susceptability to memory corruptionissues [0, 1, 2] by ensuring to only operate on supplied argumentswhich are deemed trusted by the BPF verifier. Typically, this meansthat only pointers to a struct path which have been referenced countedmay be supplied.In addition to the new bpf_path_d_path() BPF kfunc, we also add aKF_ACQUIRE based BPF kfunc bpf_get_task_exe_file() and KF_RELEASEcounterpart BPF kfunc bpf_put_file(). This is so that the newbpf_path_d_path() BPF kfunc can be used more flexibily from within thecontext of a BPF LSM program. It's rather common to ascertain thebacking executable file for the calling process by performing thefollowing walk current->mm->exe_file while instrumenting a givenoperation from the context of the BPF LSM program. However, walkingcurrent->mm->exe_file directly is never deemed to be OK, and doing sofrom both inside and outside of BPF LSM program context should beconsidered as a bug. Using bpf_get_task_exe_file() and in turnbpf_put_file() will allow BPF LSM programs to reliably get and putreferences to current->mm->exe_file.As of now, all the newly introduced BPF kfuncs within this patch arelimited to BPF LSM program types. These can be either sleepable ornon-sleepable variants of BPF LSM program types.[0] https://lore.kernel.org/bpf/CAG48ez0ppjcT=QxU-jtCUfb5xQb3mLr=5FcwddF_VKfEBPs_Dg@mail.gmail.com/[1] https://lore.kernel.org/bpf/20230606181714.532998-1-jolsa@kernel.org/[2] https://lore.kernel.org/bpf/20220219113744.1852259-1-memxor@gmail.com/Acked-by: Christian Brauner Signed-off-by: Matt Bobrowski Acked-by: Song Liu Link: https://lore.kernel.org/r/20240731110833.1834742-2-mattbobrowski@google.comSigned-off-by: Alexei Starovoitov List of files: /linux-6.15/fs/Makefile

netfs, fscache: Move fs/fscache/* into fs/netfs/There's a problem with dependencies between netfslib and fscache as eachwants to access some functions of the other. Deal with this by movingfs/fscache/* into fs/netfs/ and renaming those files to begin with"fscache-".For the moment, the moved files are changed as little as possible and anfscache module is still built.

All ofthe kernel sysctl APIs always share the same directory, and racesagainst using it should end up re-using the same single createddirectory.And so something we can do eventually is do away with all the base stuff.For now it's fine, it's not creating an issue.

ab171b95 - fs: move namespace sysctls and declare fs base directory

Sat, 22 Jan 2022 06:13:27 +0000

fs: move namespace sysctls and declare fs base directoryThis moves the namespace sysctls to its own file as part of thekernel/sysctl.c spring cleaningSince we have now removed all sysctls for "fs", we now have to declareit on the filesystem code, we do that using the new helper, whichreduces boiler plate code.We rename init_fs_shared_sysctls() to init_fs_sysctls() to reflect thatnow fs/sysctls.c is taking on the burden of being the first to registerthe base directory as well.Lastly, since init code will load in the order in which we link it wehave to move the sysctl code to be linked in early, so that its earlyinit routine runs prior to other fs code. This way, other filesystemcode can register their own sysctls using the helpers after this: * register_sysctl_init() * register_sysctl()Link: https://lkml.kernel.org/r/20211129211943.640266-3-mcgrof@kernel.orgSigned-off-by: Luis Chamberlain Cc: Al Viro Cc: Anil S Keshavamurthy Cc: Antti Palosaari Cc: Christian Brauner Cc: "David S.
