2024-02-05bcachefs: install fd later to avoid race with closeMathias Krause
Calling fd_install() makes a file reachable for userland, including the possibility to close the file descriptor, which leads to calling its 'release' hook. If that happens before the code had a chance to bump the reference of the newly created task struct, the release callback will call put_task_struct() too early, leading to the premature destruction of the kernel thread. Avoid that race by calling fd_install() later, after all the setup is done.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing and eventfs fixes from Steven Rostedt: - Fix the return code for ring_buffer_poll_wait() It was returing a -EINVAL instead of EPOLLERR. - Zero out the tracefs_inode so that all fields are initialized. The ti->private could have had stale data, but instead of just initializing it to NULL, clear out the entire structure when it is allocated. - Fix a crash in timerlat The hrtimer was initialized at read and not open, but is canceled at close. If the file was opened and never read the close will pass a NULL pointer to hrtime_cancel(). - Rewrite of eventfs. Linus wrote a patch series to remove the dentry references in the eventfs_inode and to use ref counting and more of proper VFS interfaces to make it work. - Add warning to put_ei() if ei is not set to free. That means something is about to free it when it shouldn't. - Restructure the eventfs_inode to make it more compact, and remove the unused llist field. - Remove the fsnotify*() funtions for when the inodes were being created in the lookup code. It doesn't make sense to notify about creation just because something is being looked up. - The inode hard link count was not accurate. It was being updated when a file was looked up. The inodes of directories were updating their parent inode hard link count every time the inode was created. That means if memory reclaim cleaned a stale directory inode and the inode was lookup up again, it would increment the parent inode again as well. Al Viro said to just have all eventfs directories have a hard link count of 1. That tells user space not to trust it. * tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Keep all directory links at 1 eventfs: Remove fsnotify*() functions from lookup() eventfs: Restructure eventfs_inode structure to be more condensed eventfs: Warn if an eventfs_inode is freed without is_freed being set tracing/timerlat: Move hrtimer_init to timerlat_fd open() eventfs: Get rid of dentry pointers without refcounts eventfs: Clean up dentry ops and add revalidate function eventfs: Remove unused d_parent pointer field tracefs: dentry lookup crapectomy tracefs: Avoid using the ei->dentry pointer unnecessarily eventfs: Initialize the tracefs inode properly tracefs: Zero out the tracefs_inode when allocating it ring-buffer: Clean ring_buffer_poll_wait() error return

2024-02-02pidfd: kill the no longer needed do_notify_pidfd() in de_thread()Oleg Nesterov
Now that __change_pid() does wake_up_all(&pid->wait_pidfd) we can kill do_notify_pidfd(leader) in de_thread(), it calls release_task(leader) right after that and this implies detach_pid(leader, PIDTYPE_PID).
