あいさつ。涙を流しながらこのメールを書いています。私の目には大きな悲しみがあります。私の名前はイザベラ・サヨウバさんです。チュニジア出身で、ブルキナファソの病院から連絡を取ります。私はあなたに心を開いて感動したので、あなたに話す以外に選択肢はありません。私は、2011年に亡くなる前にブルキナファソのチュニジア大使と9年間働いていたSayoubaBrown氏と結婚しました。子供なしで11年間結婚した。彼はたった5日間続いた短い病気の後で死にました。彼の死後、私は再婚しないことに決めました。亡くなった夫が生きていたとき、彼は総額850万ドルを預けました。（800万5000ドル）西アフリカのブルキナファソの首都ワガドゥグーの銀行で。現在、このお金はまだ銀行にあります。彼はこのお金をブルキナファソの鉱業からの金の輸出に利用できるようにしました。最近、私の医者は私が癌と脳卒中の問題のために7ヶ月間は続かないだろうと私に言いました。私を最も悩ませているのは脳卒中の病気です。私の状態を知ったので、私はこのお金をあなたに渡して、恵まれない人々の世話をすることにしました。あなたはこのお金を私がここで指示する方法で利用するでしょう。私はあなたにあなたの個人的な使用のために総お金の30パーセントを取って欲しいです。お金の70％は私の名前で孤児院を建て、通りの貧しい人々を助けるために使うでしょう。私は孤児として育ちましたが、神の家を維持するためだけに、家族には誰もいません。この病気が私をとても苦しめたので、神が私の罪を赦し、楽園で私の魂を受け入れるようにこれをしているのです。返信を受け取り次第、ブルキナファソの銀行の連絡先をお知らせします。また、銀行の現在の受取人であることを証明する権限書を発行するよう銀行長に指示します。私がここで述べたようにあなたがそれに応じて行動することを私に保証してください。イザベラ・サヨウバ夫人から。

[PATCH 5/5] io_uring: defer file assignment for links

by Jens Axboe

If an application uses direct open or accept, it knows in advance what direct descriptor value it will get as it picks it itself. This allows combined requests such as: sqe = io_uring_get_sqe(ring); io_uring_prep_openat_direct(sqe, ..., file_slot); sqe->flags |= IOSQE_IO_LINK | IOSQE_CQE_SKIP_SUCCESS; sqe = io_uring_get_sqe(ring); io_uring_prep_read(sqe,file_slot, buf, buf_size, 0); sqe->flags |= IOSQE_FIXED_FILE; io_uring_submit(ring); where we prepare both a file open and read, and only get a completion event for the read when both have completed successfully. Currently links are fully prepared before the head is issued, but that fails if the dependent link needs a file assigned that isn't valid until the head has completed. Conversely, if the same chain is performed but the fixed file slot is already valid, then we would be unexpectedly returning data from the old file slot rather than the newly opened one. Make sure we're consistent here. Allow deferral of file setup, which makes this documented case work.

[PATCH v4.14 v4.19] fuse: fix pipe buffer lifetime for direct_io

by Zach O'Keefe

From: Miklos Szeredi <mszeredi(a)redhat.com> commit 0c4bcfdecb1ac0967619ee7ff44871d93c08c909 upstream. In FOPEN_DIRECT_IO mode, fuse_file_write_iter() calls fuse_direct_write_iter(), which normally calls fuse_direct_io(), which then imports the write buffer with fuse_get_user_pages(), which uses iov_iter_get_pages() to grab references to userspace pages instead of actually copying memory. On the filesystem device side, these pages can then either be read to userspace (via fuse_dev_read()), or splice()d over into a pipe using fuse_dev_splice_read() as pipe buffers with &nosteal_pipe_buf_ops. This is wrong because after fuse_dev_do_read() unlocks the FUSE request, the userspace filesystem can mark the request as completed, causing write() to return. At that point, the userspace filesystem should no longer have access to the pipe buffer. Fix by copying pages coming from the user address space to new pipe buffers.

[PATCH v2 02/19] exportfs: support idmapped mounts

by Christian Brauner

Make the two locations where exportfs helpers check permission to lookup a given inode idmapped mount aware by switching it to the lookup_one() helper. This is a bugfix for the open_by_handle_at() system call which doesn't take idmapped mounts into account currently. It's not tied to a specific commit so we'll just Cc stable. In addition this is required to support idmapped base layers in overlay. The overlay filesystem uses exportfs to encode and decode file handles for its index=on mount option and when nfs_export=on.
