Patch series "hacking: make 'kernel hacking' menu better structurized", v3. This series is a trivial improvment for the layout of 'kernel hacking' configuration menu. Now we have many items in it which makes takes a little time to look up them since they are not well structurized yet. Early discussion is here: https://lkml.org/lkml/2019/9/1/39 This patch (of 9): Group generic kernel debugging instruments sysrq/kgdb/ubsan together into a new submenu.

Similarly to commit 8f868d68 ("pipe: Fix missing mask update after pipe_wait()") this fixes a case where the pipe rewrite ended up caching the pipe state incorrectly over a pipe lock drop event. It wasn't quite as obvious, because you needed to splice data from a pipe to a file, which is a fairly unusual operation, but it's completely wrong. Make sure we load the pipe head/tail/size information only after we've waited for there to be data in the pipe. While in that file, also make one of the splice helper functions use the canonical arghument order for pipe_empty(). That's syntactic - pipe emptiness is just that head and tail are equal, and thus mixing up head and tail doesn't really matter. It's still wrong, though. Reported-by:

Pull vfs d_inode/d_flags memory ordering fixes from Al Viro: "Fallout from tree-wide audit for ->d_inode/->d_flags barriers use. Basically, the problem is that negative pinned dentries require careful treatment - unless ->d_lock is locked or parent is held at least shared, another thread can make them positive right under us. Most of the uses turned out to be safe - the main surprises as far as filesystems are concerned were - race in dget_parent() fastpath, that might end up with the caller observing the returned dentry _negative_, due to insufficient barriers. It is positive in memory, but we could end up seeing the wrong value of ->d_inode in CPU cache. Fixed. - manual checks that result of lookup_one_len_unlocked() is positive (and rejection of negatives). Again, insufficient barriers (we might end up with inconsistent observed values of ->d_inode and ->d_flags). Fixed by switching to a new primitive that does the checks itself and returns ERR_PTR(-ENOENT) instead of a negative dentry. That way we get rid of boilerplate converting negatives into ERR_PTR(-ENOENT) in the callers and have a single place to deal with the barrier-related mess - inside fs/namei.c rather than in every caller out there. The guts of pathname resolution *do* need to be careful - the race found by Ritesh is real, as well as several similar races. Fortunately, it turns out that we can take care of that with fairly local changes in there. The tree-wide audit had not been fun, and I hate the idea of repeating it. I think the right approach would be to annotate the places where we are _not_ guaranteed ->d_inode/->d_flags stability and have sparse catch regressions. But I'm still not sure what would be the least invasive way of doing that and it's clearly the next cycle fodder" * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs/namei.c: fix missing barriers when checking positivity fix dget_parent() fastpath race new helper: lookup_positive_unlocked() fs/namei.c: pull positivity check into follow_managed() -

Pull autofs updates from Al Viro: "autofs misuses checks for ->d_subdirs emptiness; the cursors are in the same lists, resulting in false negatives. It's not needed anyway, since autofs maintains counter in struct autofs_info, containing 0 for removed ones, 1 for live symlinks and 1 + number of children for live directories, which is precisely what we need for those checks. This series switches to use of that counter and untangles the crap around its uses (it needs not be atomic and there's a bunch of completely pointless "defensive" checks). This fell out of dcache_readdir work; the main point is to get rid of ->d_subdirs abuses in there.

Merge two fixes for the pipe rework from David Howells: "Here are a couple of patches to fix bugs syzbot found in the pipe changes: - An assertion check will sometimes trip when polling a pipe because the ring size and indices used are approximate and may be being changed simultaneously. An equivalent approximate calculation was done previously, but without the assertion check, so I've just dropped the check. To make it accurate, the pipe mutex would need to be taken or the spin lock could be used - but usage of the spinlock would need to be rolled out into splice, iov_iter and other places for that. - The index mask and the max_usage values cannot be cached across pipe_wait() as F_SETPIPE_SZ could have been called during the wait. This can cause pipe_write() to break" * pipe-rework: pipe: Fix missing mask update after pipe_wait() pipe: Remove assertion from pipe_poll()

Fix pipe_write() to not cache the ring index mask and max_usage as their values are invalidated by calling pipe_wait() because the latter function drops the pipe lock, thereby allowing F_SETPIPE_SZ change them. Without this, pipe_write() may subsequently miscalculate the array indices and pipe fullness, leading to an oops like the following: BUG: KASAN: slab-out-of-bounds in pipe_write+0xc25/0xe10 fs/pipe.c:481 Write of size 8 at addr ffff8880771167a8 by task syz-executor.3/7987 ...

An assertion check was added to pipe_poll() to make sure that the ring occupancy isn't seen to overflow the ring size. However, since no locks are held when the three values are read, it is possible for F_SETPIPE_SZ to intervene and muck up the calculation, thereby causing the oops. Fix this by simply removing the assertion and accepting that the calculation might be approximate. Note that the previous code also had a similar issue, though there was no assertion check, since the occupancy counter and the ring size were not read with a lock held, so it's possible that the poll check might have malfunctioned then too. Also wake up all the waiters so that they can reissue their checks if there was a competing read or write.

7c20f116 ("bio-integrity: stop abusing bi_end_io") moves bio_integrity_free from bio_uninit() to bio_integrity_verify_fn() and bio_endio(). This way looks wrong because bio may be freed without calling bio_endio(), for example, blk_rq_unprep_clone() is called from dm_mq_queue_rq() when the underlying queue of dm-mpath is busy. So memory leak of bio integrity data is caused by commit 7c20f116. Fixes this issue by re-adding bio_integrity_free() to bio_uninit().

Links are created by chaining requests through req->list with an exception that head uses req->link_list. (e.g. link_list->list->list) Because of that, io_req_link_next() needs complex splicing to advance. Link them all through list_list. Also, it seems to be simpler and more consistent IMHO.

In case of an error io_submit_sqe() drops a request and continues without it, even if the request was a part of a link. Not only it doesn't cancel links, but also may execute wrong sequence of actions. Stop consuming sqes, and let the user handle errors. Signed-off-by:
