tcp: fix TLP timer not set when CA_STATE changes from DISORDER to OPEN
Upon receiving a cumulative ACK that changes the congestion state from
Disorder to Open, the TLP timer is not set. If the sender is app-limited,
it can only wait for the RTO timer to expire and retransmit.
The reason for this is that the TLP timer is set before the congestion
state changes in tcp_ack(), so we delay the time point of calling
tcp_set_xmit_timer() until after tcp_fastretrans_alert() returns and
remove the FLAG_SET_XMIT_TIMER from ack_flag when the RACK reorder timer
is set.
This commit has two additional benefits:
1) Make sure to reset RTO according to RFC6298 when receiving ACK, to
avoid spurious RTO caused by RTO timer early expires.
2) Reduce the xmit timer reschedule once per ACK when the RACK reorder
timer is set.

tcp: make TCP_USER_TIMEOUT accurate for zero window probes
The TCP_USER_TIMEOUT is checked by the 0-window probe timer. As the timer has backoff with a max interval of about two minutes, the actual timeout for TCP_USER_TIMEOUT can be off by up to two minutes. In this patch the TCP_USER_TIMEOUT is made more accurate by taking it into account when computing the timer value for the 0-window probes. This patch is similar to and builds on top of the one that made TCP_USER_TIMEOUT accurate for RTOs in commit |

Merge branch 'fix-and-move-definitions-of-mrp-data-structures'
Rasmus Villemoes says: ==================== fix and move definitions of MRP data structures We unnecessarily included packet structures of MRP in a uAPI header. Turns out that some of them were in fact broken due to lack of packing, so let's take this chance to remove them completely. Leave it to user space to create its own, correct definitions. Said structures are not used in the user space <> kernel communication. ==================== Link: https://lore.kernel.org/r/20210121204037.61390-1-rasmus.villemoes@prevas.dk Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: mrp: move struct definitions out of uapi
None of these are actually used in the kernel/userspace interface - there's a userspace component of implementing MRP, and userspace will need to construct certain frames to put on the wire, but there's no reason the kernel should provide the relevant definitions in a UAPI header. In fact, some of those definitions were broken until previous commit, so only keep the few that are actually referenced in the kernel code, and move them to the br_private_mrp.h header.

net: mrp: fix definitions of MRP test packets
Wireshark says that the MRP test packets cannot be decoded - and the reason for that is that there's a two-byte hole filled with garbage between the "transitions" and "timestamp" members. So Wireshark decodes the two garbage bytes and the top two bytes of the timestamp written by the kernel as the timestamp value (which thus fluctuates wildly), and interprets the lower two bytes of the timestamp as a new (type, length) pair, which is of course broken. Even though this makes the timestamp field in the struct unaligned, it actually makes it end up on a 32 bit boundary in the frame as mandated by the standard, since it is preceded by a two byte TLV header. The struct definitions live under include/uapi/, but they are not really part of any kernel<->userspace API/ABI, so fixing the definitions by adding the packed attribute should not cause any compatibility issues.

ALSA: usb-audio: workaround for iface reset issue
The recently introduced sample rate validation code seems causing a
problem on some devices; namely, after performing this, the bus gets
screwed and it influences even on other USB devices.
As a quick workaround, perform it only for the necessary devices;
currently MOTU devices are known to need the valid altset checks, so
filter out other devices.

ALSA: pcm: One more dependency for hw constraints
The fix for a long-standing USB-audio bug required one more dependency
variable to be added to the hw constraints. Unfortunately I didn't
realize at debugging that the new addition may result in the overflow
of the dependency array of each snd_pcm_hw_rule (up to three plus a
sentinel), because USB-audio driver adds one more dependency only for
a certain device and bus, hence it works as is for many devices. But
in a bad case, a simple open always results in -EINVAL (with kernel
WARNING if CONFIG_SND_DEBUG is set) no matter what is passed.
Since the dependencies are real and unavoidable (USB-audio restricts
the hw_params per looping over the format/rate/channels combos), the
only good solution seems to raise the bar for one more dependency for
snd_pcm_hw_rule -- so does this patch: now the hw constraint
dependencies can be up to four.

cifs: do not fail __smb_send_rqst if non-fatal signals are pending
RHBZ 1848178
The original intent of returning an error in this function
in the patch:
"CIFS: Mask off signals when sending SMB packets"
was to avoid interrupting packet send in the middle of
sending the data (and thus breaking an SMB connection),
but we also don't want to fail the request for non-fatal
signals even before we have had a chance to try to
send it (the reported problem could be reproduced e.g.
by exiting a child process when the parent process was in
the midst of calling futimens to update a file's timestamps).
In addition, since the signal may remain pending when we enter the
sending loop, we may end up not sending the whole packet before
TCP buffers become full. In this case the code returns -EINTR
but what we need here is to return -ERESTARTSYS instead to
allow system calls to be restarted.

net: octeontx2: Make sure the buffer is 128 byte aligned
The octeontx2 hardware needs the buffer to be 128 byte aligned.
But in the current implementation of napi_alloc_frag(), it can't
guarantee the return address is 128 byte aligned even the request size
is a multiple of 128 bytes, so we have to request an extra 128 bytes and
use the PTR_ALIGN() to make sure that the buffer is aligned correctly.

drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]
of_match_node() calls __of_match_node() which loops though the entries of
matches array. It stops when condition:
(matches->name[0] || matches->type[0] || matches->compatible[0]) is
false. Thus, add a null entry at the end of at91_soc_allowed_list[]
array.

- Fix DM integrity crash if "recalculate" used without "internal_hash"
- Fix DM integrity "recalculate" support to prevent recalculating checksums if we use internal_hash or journal_hash with a key (e.g. HMAC). Use of crypto as a means to prevent malicious corruption requires further changes and was never a design goal for dm-integrity's primary usecase of detecting accidental corruption. - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix that was merged for 5.11-rc4. - Fix DM core's dm_get_device() to avoid filesystem lookup to get block device (if possible). -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmALT1YTHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWs16B/4tO+s2OPtZ5ge8+SQdADPyrPn9thCU SSDeJ0k8WZCETzDw8DI1u5r08DS+Ji4vUruHx4FMrmUZkIeaW4OfyVb6UiWVpDQu gHmDL65WjWBMAtJOg2hHukHX04siTESBg67svrCuWVq7uOMha9IyDkrkb1JijjYt EcGwaYhtWkZM+8ACUlgaTmuWehQOWRtr6qE/BDtARdqXKgrlODGumBDlcQ8GsABr Zm2PE8YOCWJyynGhoRYy94td8/SDrsHSqWI0aNTETUVzGr30xIl54BikOzplbyWo pB0PhiIqimPVzkF0loYuZ+PQyK3ayBEmajW7oC7/hT2VrRXS8SnMHbwv =csNG -----END PGP SIGNATURE----- Merge tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM integrity crash if "recalculate" used without "internal_hash" - Fix DM integrity "recalculate" support to prevent recalculating checksums if we use internal_hash or journal_hash with a key (e.g. HMAC).

bpf, cgroup: Fix optlen WARN_ON_ONCE toctou
A toctou issue in `__cgroup_bpf_run_filter_getsockopt` can trigger a
WARN_ON_ONCE in a check of `copy_from_user`.
`*optlen` is checked to be non-negative in the individual getsockopt
functions beforehand. Changing `*optlen` in a race to a negative value
will result in a `copy_from_user(ctx.optval, optval, ctx.optlen)` with
`ctx.optlen` being a negative integer.

perf tools fixes for 5.11, 2nd batch:
- Fix id index used in Intel PT for heterogeneous systems.
- Fix overrun issue in 'perf script' for dynamically-allocated PMU type number.
- Fix 'perf stat' metrics containing the 'duration_time' synthetic event.
- Fix system PMU 'perf stat' metrics.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

io_uring: fix short read retries for non-reg files
Sockets and other non-regular files may actually expect short reads to happen, don't retry reads for them. Because non-reg files don't set FMODE_BUF_RASYNC and so it won't do second/retry do_read, we can filter out those cases after first do_read() attempt with ret>0.

io_uring: fix SQPOLL IORING_OP_CLOSE cancelation state
IORING_OP_CLOSE is special in terms of cancelation, since it has an
intermediate state where we've removed the file descriptor but hasn't
closed the file yet. For that reason, it's currently marked with
IO_WQ_WORK_NO_CANCEL to prevent cancelation. This ensures that the op
is always run even if canceled, to prevent leaving us with a live file
but an fd that is gone. However, with SQPOLL, since a cancel request
doesn't carry any resources on behalf of the request being canceled, if
we cancel before any of the close op has been run, we can end up with
io-wq not having the ->files assigned. This can result in the following
oops reported by Joseph:

Fix this by moving the IO_WQ_WORK_NO_CANCEL until _after_ we've modified
the fdtable. Canceling before this point is totally fine, and running
it in the io-wq context _after_ that point is also fine.
For 5.12, we'll handle this internally and get rid of the no-cancel
flag, as IORING_OP_CLOSE is the only user of it.

The culprit was kprobe_breakpoint_ss_handler() returning DBG_HOOK_ERROR which leads to the Unexpected kernel BRK exception. Reverting commit |

sched: Relax the set_cpus_allowed_ptr() semantics
Now that we have KTHREAD_IS_PER_CPU to denote the critical per-cpu tasks to retain during CPU offline, we can relax the warning in set_cpus_allowed_ptr(). Any spurious kthread that wants to get on at the last minute will get pushed off before it can run. While during CPU online there is no harm, and actual benefit, to allowing kthreads back on early, it simplifies hotplug code and fixes a number of outstanding races.

sched: Prepare to use balance_push in ttwu()
In preparation of using the balance_push state in ttwu() we need it to provide a reliable and consistent state. The immediate problem is that rq->balance_callback gets cleared every schedule() and then re-set in the balance_push_callback() itself. This is not a reliable signal, so add a variable that stays set during the entire time. Also move setting it before the synchronize_rcu() in sched_cpu_deactivate(), such that we get guaranteed visibility to ttwu(), which is a preempt-disable region.

workqueue: Restrict affinity change to rescuer
create_worker() will already set the right affinity using kthread_bind_mask(), this means only the rescuer will need to change it's affinity. Howveer, while in cpu-hot-unplug a regular task is not allowed to run on online&&!active as it would be pushed away quite agressively. We need KTHREAD_IS_PER_CPU to survive in that environment. Therefore set the affinity after getting that magic flag.

workqueue: Tag bound workers with KTHREAD_IS_PER_CPU
Mark the per-cpu workqueue workers as KTHREAD_IS_PER_CPU. Workqueues have unfortunate semantics in that per-cpu workers are not default flushed and parked during hotplug, however a subset does manual flush on hotplug and hard relies on them for correctness. Therefore play silly games..

kthread: Extract KTHREAD_IS_PER_CPU
There is a need to distinguish geniune per-cpu kthreads from kthreads that happen to have a single CPU affinity. Geniune per-cpu kthreads are kthreads that are CPU affine for correctness, these will obviously have PF_KTHREAD set, but must also have PF_NO_SETAFFINITY set, lest userspace modify their affinity and ruins things. However, these two things are not sufficient, PF_NO_SETAFFINITY is also set on other tasks that have their affinities controlled through other means, like for instance workqueues. Therefore another bit is needed; it turns out kthread_create_per_cpu() already has such a bit: KTHREAD_IS_PER_CPU, which is used to make kthread_park()/kthread_unpark() work correctly. Expose this flag and remove the implicit setting of it from kthread_create_on_cpu(); the io_uring usage of it seems dubious at best.
