7f3d132415 io_uring: remove MSG_NOSIGNAL from recvmsg
commit 7605c43d67face310b4b87dee1a28bc0c8cd8c0f upstream.

MSG_NOSIGNAL is not applicable for the receiving side, SIGPIPE is
generated when trying to write to a "broken pipe".  AF_PACKET's
packet_recvmsg() does enforce this, giving back EINVAL when MSG_NOSIGNAL
is set - making it unuseable in io_uring's recvmsg.

Remove MSG_NOSIGNAL from io_recvmsg_prep().

72783d2af8 io_uring/rsrc: disallow multi-source reg buffers
commit edd478269640b360c6f301f2baa04abdda563ef3 upstream.

If two or more mappings go back to back to each other they can be passed
into io_uring to be registered as a single registered buffer. That would
even work if mappings came from different sources, e.g. it's possible to
mix in this way anon pages and pages from shmem or hugetlb. That is not
a problem but it'd rather be less prone if we forbid such mixing.

a442f12e47 io_uring: add a conditional reschedule to the IOPOLL cancelation loop
commit fcc926bb857949dbfa51a7d95f3f5ebc657f198c upstream.

If the kernel is configured with CONFIG_PREEMPT_NONE, we could be
sitting in a tight loop reaping events but not giving them a chance to
finish. This results in a trace ala:

3d1f9533a3 io_uring: mark task TASK_RUNNING before handling resume/task work
commit 2f2bb1ffc9983e227424d0787289da5483b0c74f upstream.

Just like for task_work, set the task mode to TASK_RUNNING before doing
potential resume work. We're not holding any locks at this point,
but we may have already set the task state to TASK_INTERRUPTIBLE in
preparation for going to sleep waiting for events. Ensure that we set it
back to TASK_RUNNING if we have work to process, to avoid warnings on
calling blocking operations with !TASK_RUNNING.

3f32f8492e io_uring: handle TIF_NOTIFY_RESUME when checking for task_work
commit b5d3ae202fbfe055aa2a8ae8524531ee1dcab717 upstream.

If TIF_NOTIFY_RESUME is set, then we need to call resume_user_mode_work()
for PF_IO_WORKER threads. They never return to usermode, hence never get
a chance to process any items that are marked by this flag. Most notably
this includes the final put of files, but also any throttling markers set
by block cgroups.

da24142b1e io_uring: ensure that io_init_req() passes in the right issue_flags
We can't use 0 here, as io_init_req() is always invoked with the
ctx uring_lock held. Newer kernels have IO_URING_F_UNLOCKED for this,
but previously we used IO_URING_F_NONBLOCK to indicate this as well.

08681391b8 io_uring: add missing lock in io_get_file_fixed
io_get_file_fixed will access io_uring's context. Lock it if it is
invoked unlocked (eg via io-wq) to avoid a race condition with fixed
files getting unregistered.

No single upstream patch exists for this issue, it was fixed as part
of the file assignment changes that went into the 5.18 cycle.

1cd4863ea8 ANDROID: struct io_uring ABI preservation hack for 5.10.162 changes
In the 5.10.162 release, the io_uring code was synced with the version
that is in the 5.15.y kernel tree in order to resolve a huge number of
potential, and known, problems with the codebase.  This makes for a more
secure and easier-to-update-and-maintain 5.10.y kernel tree, so this is
a great thing, however this caused some issues when it comes to the
Android KABI preservation and checking tools.

A number of the io_uring structures get used in other core kernel
structures, only as "opaque" pointers, so there is not any real ABI
breakage.  But, due to the visibility of the structures going away, the
CRC values of many scheduler variables and functions were changed.

In order to preserve the CRC values, to prevent all device kernels to be
forced to rebuild for no reason whatsoever from a functional point of
view, we need to keep around the "old" io_uring structures for the CRC
calculation only.  This is done by the following definitions of struct
io_identity and struct io_uring_task which will only be visible when the
CRC calculation build happens, not in any functional kernel build.

Yes, this all is a horrible hack, and these really are not the true
structures that any code uses, but so life is in the world of stable
apis.

commit c0737fa9a5a5cf5a053bcc983f72d58919b997c6 upstream.

We have re-polling for partial IO, so a request can be polled twice. If
it used two poll entries the first time then on the second
io_arm_poll_handler() it will find the old apoll entry and NULL
kmalloc()'ed second entry, i.e. apoll->double_poll, so leaking it.

ddaaadf22b io_uring: Clean up a false-positive warning from GCC 9.3.0
commit 0d7c1153d9291197c1dc473cfaade77acb874b4b upstream.

In io_recv(), if import_single_range() fails, the @flags variable is
uninitialized, then it will goto out_free.

After the goto, the compiler doesn't know that (ret < min_ret) is
always true, so it thinks the "if ((flags & MSG_WAITALL) ..."  path
could be taken.

The complaint comes from gcc-9 (Debian 9.3.0-22) 9.3.0:
```
  fs/io_uring.c:5238 io_recvfrom() error: uninitialized symbol 'flags'
```
Fix this by bypassing the @ret and @flags check when
import_single_range() fails.

Reasons:
 1. import_single_range() only returns -EFAULT when it fails.
 2. At that point, @flags is uninitialized and shouldn't be read.

fc2491562a io_uring/net: fix fast_iov assignment in io_setup_async_msg()
commit 3e4cb6ebbb2bad201c1186bc0b7e8cf41dd7f7e6 upstream.

I hit a very bad problem during my tests of SENDMSG_ZC.
BUG(); in first_iovec_segment() triggered very easily.
The problem was io_setup_async_msg() in the partial retry case,
which seems to happen more often with _ZC.

iov_iter_iovec_advance() may change i->iov in order to have i->iov_offset
being only relative to the first element.

Which means kmsg->msg.msg_iter.iov is no longer the
same as kmsg->fast_iov.

But this would rewind the copy to be the start of
async_msg->fast_iov, which means the internal
state of sync_msg->msg.msg_iter is inconsitent.

I tested with 5 vectors with length like this 4, 0, 64, 20, 8388608
and got a short writes with:
- ret=2675244 min_ret=8388692 => remaining 5713448 sr->done_io=2675244
- ret=-EAGAIN => io_uring_poll_arm
- ret=4911225 min_ret=5713448 => remaining 802223  sr->done_io=7586469
- ret=-EAGAIN => io_uring_poll_arm
- ret=802223  min_ret=802223  => res=8388692

While this was easily triggered with SENDMSG_ZC (queued for 6.1),
it was a potential problem starting with 7ba89d2af17aa879dda30f5d5d3f152e587fc551
in 5.18 for IORING_OP_RECVMSG.
And also with 4c3c09439c08b03d9503df0ca4c7619c5842892e in 5.19
for IORING_OP_SENDMSG.

However 257e84a5377fbbc336ff563833a8712619acce56 introduced the critical
code into io_setup_async_msg() in 5.11.

e90cfb9699 io_uring: do not recalculate ppos unnecessarily
commit b4aec40015953b65f2f114641e7fd7714c8df8e6 upstream.

There is a slight optimisation to be had by calculating the correct pos
pointer inside io_kiocb_update_pos and then using that later.

It seems code size drops by a bit:

000000000000a5b0 0000000000000319 t io_write

commit d34e1e5b396a0dbaa4a29b7138df662cfb9d8e8e upstream.

Update kiocb->ki_pos at execution time rather than in io_prep_rw().
io_prep_rw() happens before the job is enqueued to a worker and so the
offset might be read multiple times before being executed once.

Ensures that the file position in a set of _linked_ SQEs will be only
obtained after earlier SQEs have completed, and so will include their
incremented file position.

e9c6556708 io_uring: ensure that cached task references are always put on exit
commit e775f93f2ab976a2cdb4a7b53063cbe890904f73 upstream.

io_uring caches task references to avoid doing atomics for each of them
per request. If a request is put from the same task that allocated it,
then we can maintain a per-ctx cache of them. This obviously relies
on io_uring always pruning caches in a reliable way, and there's
currently a case off io_uring fd release where we can miss that.

One example is a ring setup with IOPOLL, which relies on the task
polling for completions, which will free them. However, if such a task
submits a request and then exits or closes the ring without reaping
the completion, then ring release will reap and put. If release happens
from that very same task, the completed request task refs will get
put back into the cache pool. This is problematic, as we're now beyond
the point of pruning caches.

Manually drop these caches after doing an IOPOLL reap. This releases
references from the current task, which is enough. If another task
happens to be doing the release, then the caching will not be
triggered and there's no issue.

cannot perform an accept SQE on a NONBLOCK socket asynchronously.

By removing the flag if there is no pending accept then poll is armed as
usual and when a connection comes in the CQE is posted.

4bc17e6381 io_uring: allow re-poll if we made progress
commit 10c873334febaeea9aa0c25c10b5ac0951b77a5f upstream.

We currently check REQ_F_POLLED before arming async poll for a
notification to retry. If it's set, then we don't allow poll and will
punt to io-wq instead. This is done to prevent a situation where a buggy
driver will repeatedly return that there's space/data available yet we
get -EAGAIN.

However, if we already transferred data, then it should be safe to rely
on poll again. Gate the check on whether or not REQ_F_PARTIAL_IO is
also set.

f901b4bfd0 io_uring: support MSG_WAITALL for IORING_OP_SEND(MSG)
commit 4c3c09439c08b03d9503df0ca4c7619c5842892e upstream.

Like commit 7ba89d2af17a for recv/recvmsg, support MSG_WAITALL for the
send side. If this flag is set and we do a short send, retry for a
stream of seqpacket socket.

96ccba4a1a io_uring: add flag for disabling provided buffer recycling
commit 8a3e8ee56417f5e0e66580d93941ed9d6f4c8274 upstream.

If we need to continue doing this IO, then we don't want a potentially
selected buffer recycled. Add a flag for that.

Set this for recv/recvmsg if they do partial IO.

aadd9b0930 io_uring: ensure recv and recvmsg handle MSG_WAITALL correctly
commit 7ba89d2af17aa879dda30f5d5d3f152e587fc551 upstream.

We currently don't attempt to get the full asked for length even if
MSG_WAITALL is set, if we get a partial receive. If we do see a partial
receive, then just note how many bytes we did and return -EAGAIN to
get it retried.

The iov is advanced appropriately for the vector based case, and we
manually bump the buffer and remainder for the non-vector case.

abdc16c836 io_uring: improve send/recv error handling
commit 7297ce3d59449de49d3c9e1f64ae25488750a1fc upstream.

Hide all error handling under common if block, removes two extra ifs on
the success path and keeps the handling more condensed.

2fd232bbd6 io_uring: don't gate task_work run on TIF_NOTIFY_SIGNAL
commit 46a525e199e4037516f7e498c18f065b09df32ac upstream.

This isn't a reliable mechanism to tell if we have task_work pending, we
really should be looking at whether we have any items queued. This is
problematic if forward progress is gated on running said task_work. One
such example is reading from a pipe, where the write side has been closed
right before the read is started. The fput() of the file queues TWA_RESUME
task_work, and we need that task_work to be run before ->release() is
called for the pipe. If ->release() isn't called, then the read will sit
forever waiting on data that will never arise.

Fix this by io_run_task_work() so it checks if we have task_work pending
rather than rely on TIF_NOTIFY_SIGNAL for that. The latter obviously
doesn't work for task_work that is queued without TWA_SIGNAL.

a88a0d16e1 io_uring/io-wq: only free worker if it was allocated for creation
commit e6db6f9398dadcbc06318a133d4c44a2d3844e61 upstream.

We have two types of task_work based creation, one is using an existing
worker to setup a new one (eg when going to sleep and we have no free
workers), and the other is allocating a new worker. Only the latter
should be freed when we cancel task_work creation for a new worker.

189556b05e io_uring: pass in EPOLL_URING_WAKE for eventfd signaling and wakeups
[ Upstream commit 4464853277d0ccdb9914608dd1332f0fa2f9846f ]

Pass in EPOLL_URING_WAKE when signaling eventfd or doing poll related
wakups, so that we can check for a circular event dependency between
eventfd and epoll. If this flag is set when our wakeup handlers are
called, then we know we have a dependency that needs to terminate
multishot requests.

eventfd and epoll are the only such possible dependencies.

No upstream commit exists.

This imports the io_uring codebase from 5.15.85, wholesale. Changes
from that code base:

- Drop IOCB_ALLOC_CACHE, we don't have that in 5.10.
- Drop MKDIRAT/SYMLINKAT/LINKAT. Would require further VFS backports,
  and we don't support these in 5.10 to begin with.
- sock_from_file() old style calling convention.
- Use compat_get_bitmap() only for CONFIG_COMPAT=y
