Late pin control fixes for the v6.6 kernel cycle:
- Concurrent register updates in the Qualcomm LPASS pin controller gets a proper lock. - We revert a mutex fix that was causing problems: contention on the mutex or something of the sort lead to probe reordering and MMC block devices start to register in a different order, which unsuspecting userspace is not ready to handle. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEElDRnuGcz/wPCXQWMQRCzN7AZXXMFAmUy1N8ACgkQQRCzN7AZ XXM2RA/+IiRmsEc2zvyTRr2EYOe6oAxC9f515YYJnoRolt+FUbijWMvB8oB6zeJy dDByXxCercuX4y0nivRkL1G0B5QMi4OTfKPte26LxRFv6zm7brObHuK17HKnwIP7 sfLK+FT3jatl8PwwsUwc9ildXhdQ+JCD5yHarqDCqVVCiiqxINPu3GRWoDQHlDts lwyOPE2s0l6m29ms3NFM2lX13j/C7vwX+QMDWF2BZ8S0WEC7l7TYugvnBmt4zJ/6 +1h1E2nywBMd8YVCtMFRyoOhdxTxnuMSnotpHAqXH/NZ1f2c8SMilv6YLte9r6Yh BdjAFejRGF/L4uNgk65X4+3DTZbsiMWYkZXNO8zis4jAKCOo7giCvt5R45p0smul j1lAAJU5SwxUDP5Lm5IVdrSJtGj7ZcpsEJAyBRsbS1Yepqfb4S+J3F6xwz4TEp0K TCB4epS/G1Y2100PYzTdVZCrq/mbJCEYLtdmy8dFlIMh/EjZmPVNZw3VofdLgoyv VwpOtK0R8NMfxeuAQLrLs4WjxWEzf2DhbIBo8MmTI8SzdqbKHL8EwsXR5Cis09hB G2nnPpIJzTl8fKA9oGwiCCDpgxpXnmr5qh2VslCu9GpC3x2znbFxzFt8/1QU0QtT V7LnsJ3Xuy28bKscAHFNM1zPjBf8YZXLNyWVEHLUK4i///0JoFY= =CPHT -----END PGP SIGNATURE----- Merge tag 'pinctrl-v6.6-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control fixes from Linus Walleij: - Concurrent register updates in the Qualcomm LPASS pin controller gets a proper lock. - revert a mutex fix that was causing problems: contention on the mutex or something of the sort lead to probe reordering and MMC block devices start to register in a different order, which unsuspecting userspace is not ready to handle * tag 'pinctrl-v6.6-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: Revert "pinctrl: avoid unsafe code pattern in find_pinctrl()" pinctrl: qcom: lpass-lpi: fix concurrent register updates |

In the raw NAND subsystem, the major fix prevents using cached reads
with devices not supporting it. There was two bug reports about this. Aside, 3 drivers (pl353, arasan and marvell) could sometimes hide page program failures due to their their own program page helper not being fully compliant with the specification (many drivers use the default helpers shared by the core). Adding a missing check prevents these situation. Finally, the Qualcomm driver had a broken error path. In the SPI-NAND subsystem one Micron device used a wrong bitmak reporting possibly corrupted ECC status. Finally, the physmap-core got stripped from its map_rom fallback by mistake, this feature is added back. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmUyvxcACgkQJWrqGEe9 VoStmwf9HjOY3kNB37ip0NpG5viRWeLNC8hMxJOJaGZlyX6x9b/88xsBjVFc7z3s hoCBGfOnUSDXk4KfxNiYps5YqfMgb+yLeIGdsDsLhNht6Mh/YOEFzXgcD8+iudKH OpjjJnRzQHxNM3zA3Vauh1XD/j+6uvQ3BHlJpQfA+Ukv4+34Irin4/gKhZCoUedo IJNVU5hurJexCkjGk2yO+B34qD8ZXGKWeXzwsKKYB/FE55iO69GrHNdLBMnFfxu+ uU6GcV+YKroPLDs5mKH2oojKhyAhrh3gQyrNJFnCqh/sVnNCAbD75N+YC6enHeBe ovlc82AWmLUJVktsih27OsU58RnCxA== =7Xq1 -----END PGP SIGNATURE----- Merge tag 'mtd/fixes-for-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD fixes from Miquel Raynal: "In the raw NAND subsystem, the major fix prevents using cached reads with devices not supporting it.

efi/unaccepted: Fix soft lockups caused by parallel memory acceptance
Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.
The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.
To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.
A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.
Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.
Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.
The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols
When a kprobe is attached to a function that's name is not unique (is
static and shares the name with other functions in the kernel), the
kprobe is attached to the first function it finds. This is a bug as the
function that it is attaching to is not necessarily the one that the
user wants to attach to.
Instead of blindly picking a function to attach to what is ambiguous,
error with EADDRNOTAVAIL to let the user know that this function is not
unique, and that the user must use another unique function with an
address offset to get to the function they want to attach to.

iavf: initialize waitqueues before starting watchdog_task
It is not safe to initialize the waitqueues after queueing the
watchdog_task. It will be using them.
The chance of this causing a real problem is very small, because
there will be some sleeping before any of the waitqueues get used.
I got a crash only after inserting an artificial sleep in iavf_probe.
Queue the watchdog_task as the last step in iavf_probe. Add a comment to
prevent repeating the mistake.

Marco Elver explained that dma_rmb() doesn't prevent the compiler to tear up the access to
desc->opts1 which can be written to concurrently. READ_ONCE() should prevent that from
happening:

As the consequence of this fix, this KCSAN warning was eliminated.

→ 4397 if (tp->cur_tx != dirty_tx && skb)
4398 rtl8169_doorbell(tp);
4399 }
4400 }
Obviously from the code, an earlier detected data-race for tp->cur_tx was fixed in the
line 4363:
4363 while (READ_ONCE(tp->cur_tx) != dirty_tx) {
but the same solution is required for protecting the other access to tp->cur_tx:
→ 4397 if (READ_ONCE(tp->cur_tx) != dirty_tx && skb)
4398 rtl8169_doorbell(tp);
The write in the line 4254 is protected with WRITE_ONCE(), but the read in the line 4397
might have suffered read tearing under some compiler optimisations.
The fix eliminated the KCSAN data-race report for this bug.
It is yet to be evaluated what happens if tp->cur_tx changes between the test in line 4363
and line 4397. This test should certainly not be cached by the compiler in some register
for such a long time, while asynchronous writes to tp->cur_tx might have occurred in line
4254 in the meantime.

tools build: Fix llvm feature detection, still used by bpftool
When removing the BPF event for perf a feature test that checks if the
llvm devel files are availabe was removed but that is also used by
bpftool.
bpftool uses it to decide what kind of disassembly it will use: llvm or
binutils based.
Removing the tools/build/feature/test-llvm.cpp file made bpftool to
always fallback to binutils disassembly, even with the llvm devel files
installed, fix it by restoring just that small test-llvm.cpp test file.

Take care of a race between when the #VC exception is raised and when
the guest kernel gets to emulate certain instructions in SEV-{ES,SNP}
guests by:
- disabling emulation of MMIO instructions when coming from user mode
- checking the IO permission bitmap before emulating IO instructions and
verifying the memory operands of INS/OUTS insns.

i40e: xsk: remove count_mask
Cited commit introduced a neat way of updating next_to_clean that does
not require boundary checks on each increment. This was done by masking
the new value with (ring length - 1) mask. Problem is that this is
applicable only for power of 2 ring sizes, for every other size this
assumption can not be made. In turn, it leads to cleaning descriptors
out of order as well as splats:

It comes from picking wrong ring entries when cleaning xsk buffers
during pool detach.
Remove the count_mask logic and use they boundary check when updating
next_to_process (which used to be a next_to_clean).

Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as fairly
clear-cut user reported regressions. The mlx5 DMA bug was causing strife
for 390x folks. The fixes themselves are not particularly scary, tho.
No open investigations / outstanding reports at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations,
make devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve,
previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset",
needs more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting,
it was denied to plug a constant source of bugs but turns out
.NET depends on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560",
it's causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains
a single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding
(bless Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace

Merge branch 'mptcp-fixes-for-v6-6'
Mat Martineau says: ==================== mptcp: Fixes for v6.6 Patch 1 corrects the logic for MP_JOIN tests where 0 RSTs are expected. Patch 2 ensures MPTCP packets are not incorrectly coalesced in the TCP backlog queue. Patch 3 avoids a zero-window probe and associated WARN_ON_ONCE() in an expected MPTCP reinjection scenario. Patches 4 & 5 allow an initial MPTCP subflow to be closed cleanly instead of always sending RST. Associated selftest is updated. ==================== Link: https://lore.kernel.org/r/20231018-send-net-20231018-v1-0-17ecb002e41d@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

selftests: mptcp: join: no RST when rm subflow/addr
Recently, we noticed that some RST were wrongly generated when removing
the initial subflow.
This patch makes sure RST are not sent when removing any subflows or any
addresses.

mptcp: avoid sending RST when closing the initial subflow
When closing the first subflow, the MPTCP protocol unconditionally
calls tcp_disconnect(), which in turn generates a reset if the subflow
is established.
That is unexpected and different from what MPTCP does with MPJ
subflows, where resets are generated only on FASTCLOSE and other edge
scenarios.
We can't reuse for the first subflow the same code in place for MPJ
subflows, as MPTCP clean them up completely via a tcp_close() call,
while must keep the first subflow socket alive for later re-usage, due
to implementation constraints.
This patch adds a new helper __mptcp_subflow_disconnect() that
encapsulates, a logic similar to tcp_close, issuing a reset only when
the MPTCP_CF_FASTCLOSE flag is set, and performing a clean shutdown
otherwise.

The root cause of the issue is that expectations are wrong: e.g. due
to MPTCP-level re-injection we can hit the critical condition.
Explicitly avoid the zero-window probe when the subflow write queue
is not empty and drop the related warnings.

tcp: check mptcp-level constraints for backlog coalescing
The MPTCP protocol can acquire the subflow-level socket lock and
cause the tcp backlog usage. When inserting new skbs into the
backlog, the stack will try to coalesce them.
Currently, we have no check in place to ensure that such coalescing
will respect the MPTCP-level DSS, and that may cause data stream
corruption, as reported by Christoph.
Address the issue by adding the relevant admission check for coalescing
in tcp_add_backlog().
Note the issue is not easy to reproduce, as the MPTCP protocol tries
hard to avoid acquiring the subflow-level socket lock.

selftests: mptcp: join: correctly check for no RST
The commit mentioned below was more tolerant with the number of RST seen
during a test because in some uncontrollable situations, multiple RST
can be generated.
But it was not taking into account the case where no RST are expected:
this validation was then no longer reporting issues for the 0 RST case
because it is not possible to have less than 0 RST in the counter. This
patch fixes the issue by adding a specific condition.

The bitmasks for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD r30 commands are
wrong in the driver.
Update the bitmasks of these commands to the correct ones as used by the
ICSSG firmware. These bitmasks are backwards compatible and work with
any ICSSG firmware version.

rust: docs: fix logo replacement
The static files placement by `rustdoc` changed in Rust 1.67.0 [1],
but the custom code we have to replace the logo in the generated
HTML files did not get updated.
Thus update it to have the Linux logo again in the output.
Hopefully `rustdoc` will eventually support a custom logo from
a local file [2], so that we do not need to maintain this hack
on our side.
