2024-07-24pidfs: add selftests for new namespace ioctlsChristian Brauner1-31/+227
Add selftests to verify that deriving namespace file descriptors from pidfd file descriptors works correctly. Link: https://lore.kernel.org/r/20240722-work-pidfs-69dbea91edab@brauner Signed-off-by: Christian Brauner <[email protected]>
2024-07-24pidfs: handle kernels without namespaces cleanlyChristian Brauner1-23/+42
The nsproxy structure contains nearly all of the namespaces associated with a task. When a given namespace type is not supported by this kernel the rules whether the corresponding pointer in struct nsproxy is NULL or always init_<ns_type>_ns differ per namespace. Ideally, that wouldn't be the case and for all namespace types we'd always set it to init_<ns_type>_ns when the corresponding namespace type isn't supported. Make sure we handle all namespaces where the pointer in struct nsproxy can be NULL when the namespace type isn't supported.

2024-07-24vfs: correct the comments of vfs_*() helpersCongjie Zhou1-13/+13
correct the comments of vfs_*() helpers in fs/namei.c, including: 1. vfs_create() 2. vfs_mknod() 3. vfs_mkdir() 4. vfs_rmdir() 5. vfs_symlink() All of them come from the same commit: 6521f8917082 "namei: prepare for idmapped mounts" The @dentry is actually the dentry of child directory rather than base directory(parent directory), and thus the @dir has to be modified due to the change of @dentry.

2024-07-24vfs: handle __wait_on_freeing_inode() and evict() raceMateusz Guzik1-0/+20
Lockless hash lookup can find and lock the inode after it gets the I_FREEING flag set, at which point it blocks waiting for teardown in evict() to finish. However, the flag is still set even after evict() wakes up all waiters. This results in a race where if the inode lock is taken late enough, it can happen after both hash removal and wakeups, meaning there is nobody to wake the racing thread up. This worked prior to RCU-based lookup because the entire ordeal was synchronized with the inode hash lock. Since unhashing requires the inode lock, we can safely check whether it happened after acquiring it.

2024-07-23cifs: mount with "unix" mount option for SMB1 incorrectly handledSteve French1-0/+7
Although by default we negotiate CIFS Unix Extensions for SMB1 mounts to Samba (and they work if the user does not specify "unix" or "posix" or "linux" on mount), and we do properly handle when a user turns them off with "nounix" mount parm. But with the changes to the mount API we broke cases where the user explicitly specifies the "unix" option (or equivalently "linux" or "posix") on mount with vers=1.0 to Samba or other servers which support the CIFS Unix Extensions. "mount error(95): Operation not supported" and logged: "CIFS: VFS: Check vers= mount option. SMB3.11 disabled but required for POSIX extensions" even though CIFS Unix Extensions are supported for vers=1.0 This patch fixes the case where the user specifies both "unix" (or equivalently "posix" or "linux") and "vers=1.0" on mount to a server which supports the CIFS Unix Extensions.

2024-07-23arm64/vdso: Remove --hash-style=sysvFangrui Song2-2/+2
glibc added support for .gnu.hash in 2006 and .hash has been obsoleted for more than one decade in many Linux distributions. Using --hash-style=sysv might imply unaddressed issues and confuse readers. Just drop the option and rely on the linker default, which is likely "both", or "gnu" when the distribution really wants to eliminate sysv hash overhead. Similar to commit 6b7e26547fad ("x86/vdso: Emit a GNU hash").
