[ Upstream commit 4bb3ba7b74fceec6f558745b25a43c6521cf5506 ]
The 'len' variable can't be negative when assigned the result of
'min_t' because all 'min_t' parameters are cast to unsigned int,
and then the minimum one is chosen.
To fix the logic, check 'len' as read from 'optlen',

The sock's skb still uses a outdated route cache and was sent to

To avoid this error we should update fib node's version when

[ Upstream commit 7a4b21250bf79eef26543d35bd390448646c536b ]
The stackmap code relies on roundup_pow_of_two() to compute the number
of hash buckets, and contains an overflow check by checking if the
resulting value is 0. However, on 32-bit arches, the roundup code itself
can overflow by doing a 32-bit left-shift of an unsigned long value,
which is undefined behaviour, so it is not guaranteed to truncate
neatly. This was triggered by syzbot on the DEVMAP_HASH type, which
contains the same check, copied from the hashtab code.
The commit in the fixes tag actually attempted to fix this, but the fix
did not account for the UB, so the fix only works on CPUs where an
overflow does result in a neat truncation to zero, which is not
guaranteed. Checking the value before rounding does not have this
problem.

[ Upstream commit 78e3639fc8031275010c3287ac548c0bc8de83b1 ]
The "pending connections" feature was originally introduced with commit
4c67bc74f016 ("[Bluetooth] Support concurrent connect requests") and
6bd57416127e ("[Bluetooth] Handling pending connect attempts after
inquiry") to handle controllers supporting only a single connection request
at a time. Later things were extended to also cancel ongoing inquiries on
connect() with commit 89e65975fea5 ("Bluetooth: Cancel Inquiry before
Create Connection").
With commit a9de9248064b ("[Bluetooth] Switch from OGF+OCF to using only
opcodes"), hci_conn_check_pending() was introduced as a helper to
consolidate a few places where we check for pending connections (indicated
by the BT_CONNECT2 flag) and then try to connect.
This refactoring commit also snuck in two more calls to
hci_conn_check_pending():
- One is in the failure callback of hci_cs_inquiry(), this one probably
makes sense: If we send an "HCI Inquiry" command and then immediately
after a "Create Connection" command, the "Create Connection" command might
fail before the "HCI Inquiry" command, and then we want to retry the
"Create Connection" on failure of the "HCI Inquiry".
- The other added call to hci_conn_check_pending() is in the event handler
for the "Remote Name" event, this seems unrelated and is possibly a
copy-paste error, so remove that one.

Fix "double" clearing of interrupts, which can cause external events
or timestamps to be missed.
The E1000_TSIRC Time Sync Interrupt Cause register can be cleared in two
ways, by either reading it or by writing '1' into the specific cause
bit. This is documented in section 8.16.1.
The following flow was used:
1. read E1000_TSIRC into 'tsicr';
2. handle the interrupts present into 'tsirc' and mark them in 'ack';
3. write 'ack' into E1000_TSICR;
As both (1) and (3) will clear the interrupt cause, if the same
interrupt happens again between (1) and (3) it will be ignored,
causing events to be missed.
Remove the extra clear in (3).

When building with CONFIG_XEN_PV=y, .text symbols are emitted into
the .notes section so that Xen can find the "startup_xen" entry point.
This information is used prior to booting the kernel, so relocations
are not useful. In fact, performing relocations against the .notes
section means that the KASLR base is exposed since /sys/kernel/notes
is world-readable.
To avoid leaking the KASLR base without breaking unprivileged tools that
are expecting to read /sys/kernel/notes, skip performing relocations in
the .notes section. The values readable in .notes are then identical to
those found in System.map.

[ Upstream commit 0feda94c868d396fac3b3cb14089d2d989a07c72 ]
On many systems that have an AMD IOMMU the following sequence of
warnings is observed during bootup.
```
pci 0000:00:00.2 can't derive routing for PCI INT A
pci 0000:00:00.2: PCI INT A: not connected
```
This series of events happens because of the IOMMU initialization
sequence order and the lack of _PRT entries for the IOMMU.
During initialization the IOMMU driver first enables the PCI device
using pci_enable_device(). This will call acpi_pci_irq_enable()
which will check if the interrupt is declared in a PCI routing table
(_PRT) entry. According to the PCI spec [1] these routing entries
are only required under PCI root bridges:
The _PRT object is required under all PCI root bridges
The IOMMU is directly connected to the root complex, so there is no
parent bridge to look for a _PRT entry. The first warning is emitted
since no entry could be found in the hierarchy. The second warning is
then emitted because the interrupt hasn't yet been configured to any
value. The pin was configured in pci_read_irq() but the byte in
PCI_INTERRUPT_LINE return 0xff which means "Unknown".
After that sequence of events pci_enable_msi() is called and this
will allocate an interrupt.
That is both of these warnings are totally harmless because the IOMMU
uses MSI for interrupts. To avoid even trying to probe for a _PRT
entry mark the IOMMU as IRQ managed. This avoids both warnings.

bcm4331 seems to not function correctly with QoS support. This may be due
to issues with currently available firmware or potentially a device
specific issue.
When queues that are not of the default "best effort" priority are
selected, traffic appears to not transmit out of the hardware while no
errors are returned. This behavior is present among all the other priority
queues: video, voice, and background. While this can be worked around by
setting a kernel parameter, the default behavior is problematic for most
users and may be difficult to debug. This patch offers a working out-of-box
experience for bcm4331 users.

[ Upstream commit 14274d0bd31b4debf28284604589f596ad2e99f2 ]
So far, get_device_system_crosststamp() unconditionally passes
system_counterval.cycles to timekeeping_cycles_to_ns(). But when
interpolating system time (do_interp == true), system_counterval.cycles is
before tkr_mono.cycle_last, contrary to the timekeeping_cycles_to_ns()
expectations.
On x86, CONFIG_CLOCKSOURCE_VALIDATE_LAST_CYCLE will mitigate on
interpolating, setting delta to 0. With delta == 0, xtstamp->sys_monoraw
and xtstamp->sys_realtime are then set to the last update time, as
implicitly expected by adjust_historical_crosststamp(). On other
architectures, the resulting nonsense xtstamp->sys_monoraw and
xtstamp->sys_realtime corrupt the xtstamp (ts) adjustment in
adjust_historical_crosststamp().
Fix this by deriving xtstamp->sys_monoraw and xtstamp->sys_realtime from
the last update time when interpolating, by using the local variable
"cycles". The local variable already has the right value when
interpolating, unlike system_counterval.cycles.

[ Upstream commit 87a41130881995f82f7adbafbfeddaebfb35f0ef ]
The cycle_between() helper checks if parameter test is in the open interval
(before, after). Colloquially speaking, this also applies to the counter
wrap-around special case before > after. get_device_system_crosststamp()
currently uses cycle_between() at the first call site to decide whether to
interpolate for older counter readings.
get_device_system_crosststamp() has the following problem with
cycle_between() testing against an open interval: Assume that, by chance,
cycles == tk->tkr_mono.cycle_last (in the following, "cycle_last" for
brevity). Then, cycle_between() at the first call site, with effective
argument values cycle_between(cycle_last, cycles, now), returns false,
enabling interpolation. During interpolation,
get_device_system_crosststamp() will then call cycle_between() at the
second call site (if a history_begin was supplied). The effective argument
values are cycle_between(history_begin->cycles, cycles, cycles), since
system_counterval.cycles == interval_start == cycles, per the assumption.
Due to the test against the open interval, cycle_between() returns false
again. This causes get_device_system_crosststamp() to return -EINVAL.
This failure should be avoided, since get_device_system_crosststamp() works
both when cycles follows cycle_last (no interpolation), and when cycles
precedes cycle_last (interpolation). For the case cycles == cycle_last,
interpolation is actually unneeded.
Fix this by changing cycle_between() into timestamp_in_interval(), which
now checks against the closed interval, rather than the open interval.
This changes the get_device_system_crosststamp() behavior for three corner
cases:
1. Bypass interpolation in the case cycles == tk->tkr_mono.cycle_last,
fixing the problem described above.
2. At the first timestamp_in_interval() call site, cycles == now no longer
causes failure.
3. At the second timestamp_in_interval() call site, history_begin->cycles
== system_counterval.cycles no longer causes failure.
adjust_historical_crosststamp() also works for this corner case,
where partial_history_cycles == total_history_cycles.
These behavioral changes should not cause any problems.

[ Upstream commit f98364e926626c678fb4b9004b75cacf92ff0662 ]
This patch is against CVE-2023-6270. The description of cve is:
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
`struct net_device`, and a use-after-free can be triggered by racing
between the free on the struct and the access through the `skbtxq`
global queue. This could lead to a denial of service condition or
potential code execution.
In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.
This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

A while ago, we changed the way that select() and poll() preallocate
a temporary buffer just under the size of the static warning limit of
1024 bytes, as clang was frequently going slightly above that limit.
The warnings have recently returned and I took another look. As it turns
out, clang is not actually inherently worse at reserving stack space,
it just happens to inline do_select() into core_sys_select(), while gcc
never inlines it.
Annotate do_select() to never be inlined and in turn remove the special
case for the allocation size. This should give the same behavior for
both clang and gcc all the time and once more avoids those warnings.

When resetting the bus after a gap count error, use a long rather than
short bus reset.
IEEE 1394-1995 uses only long bus resets. IEEE 1394a adds the option of
short bus resets. When video or audio transmission is in progress and a
device is hot-plugged elsewhere on the bus, the resulting bus reset can
cause video frame drops or audio dropouts. Short bus resets reduce or
eliminate this problem. Accordingly, short bus resets are almost always
preferred.
However, on a mixed 1394/1394a bus, a short bus reset can trigger an
immediate additional bus reset. This double bus reset can be interpreted
differently by different nodes on the bus, resulting in an inconsistent gap
count after the bus reset. An inconsistent gap count will cause another bus
reset, leading to a neverending bus reset loop. This only happens for some
bus topologies, not for all mixed 1394/1394a buses.
By instead sending a long bus reset after a gap count inconsistency, we
avoid the doubled bus reset, restoring the bus to normal operation.
