Reading the hardware registers of the &slimbam on RB3 reveals that the BAM
supports only 23 pipes (channels) and supports 4 EEs instead of 2. This
hasn't caused problems so far since nothing is using the extra channels,
but attempting to use them would lead to crashes.
The bam_dma driver might warn in the future if the num-channels in the DT
are wrong, so correct the properties in the DT to avoid future regressions.

Commit b00bee8afa ("irqchip: Convert generic irqchip locking to guards")
replaced calls to irq_gc_lock_irq{save,restore}() with
guard(raw_spinlock_irq).
However, in irq-atmel-aic5.c and irq-atmel-aic.c, the xlate callback is
used in the early boot process, before interrupts are initially enabled.
As its destructor enables interrupts, this triggers the warning in
start_kernel():
WARNING: CPU: 0 PID: 0 at init/main.c:1024 start_kernel+0x4d0/0x5dc
Interrupts were enabled early
Fix this by using guard(raw_spinlock_irqsave) instead.

When using NVME on SG2044, the NVME drvier always complains about "I/O tag
XXX (XXX) QID XX timeout, completion polled", which is caused by the broken
affinity setting mechanism of the sg2042-msi driver.
The PLIC driver can only the set the affinity when enabled, but the
sg2042-msi driver invokes the affinity setter in disabled state, which
causes the change to be lost.
Cure this by implementing the irq_startup()/shutdown() callbacks, which
allow to startup (enabled) the underlying PLIC first.

As the RISC-V PLIC cannot apply affinity settings without invoking
irq_enable(), it will make the interrupt unavailble when used as an
underlying interrupt chip for the MSI controller.
Implement the irq_startup() and irq_shutdown() callbacks for the PCI MSI
and MSI-X templates.
For chips that specify MSI_FLAG_PCI_MSI_STARTUP_PARENT, the parent startup
and shutdown functions are invoked. That allows the interrupt on the parent
chip to be enabled if the interrupt has not been enabled during
allocation. This is necessary for MSI controllers which use PLIC as
underlying parent interrupt chip.

As the MSI controller on SG2044 uses PLIC as the underlying interrupt
controller, it needs to call irq_enable() and irq_disable() to
startup/shutdown interrupts. Otherwise, the MSI interrupt can not be
startup correctly and will not respond any incoming interrupt.
Introduce irq_chip_startup_parent() and irq_chip_shutdown_parent() to allow
the interrupt controller to call the irq_startup()/irq_shutdown() callbacks
of the parent interrupt chip.
In case the irq_startup()/irq_shutdown() callbacks are not implemented for
the parent interrupt chip, this will fallback to irq_chip_enable_parent()
or irq_chip_disable_parent().

Since commit 3309323241 ("drm/gpuvm: Kill drm_gpuva_init()") MSM
driver fails to init, failing with "[drm:msm_gpu_init] *ERROR* could not
allocate memptrs: -22" errors. The mentioned commit reworked the
function, but didn't take into account that op_map is initialized at the
top of the function, while ranges might change if GPUVM is managed by
the kernel.
Move op_mode initialization after finalizing all addresses and right
before the drm_gpuva_init_from_op() call.

- Fix rtla and latency tooling pkg-config errors
If libtraceevent and libtracefs is installed, but their corresponding '.pc'
files are not installed, it reports that the libraries are missing and
confuses the developer. Instead, report that the pkg-config files are
missing and should be installed.
- Fix overflow bug of the parser in trace_get_user()
trace_get_user() uses the parsing functions to parse the user space strings.
If the parser fails due to incorrect processing, it doesn't terminate the
buffer with a nul byte. Add a "failed" flag to the parser that gets set when
parsing fails and is used to know if the buffer is fine to use or not.
- Remove a semicolon that was at an end of a comment line
- Fix register_ftrace_graph() to unregister the pm notifier on error
The register_ftrace_graph() registers a pm notifier but there's an error
path that can exit the function without unregistering it. Since the function
returns an error, it will never be unregistered.
- Allocate and copy ftrace hash for reader of ftrace filter files
When the set_ftrace_filter or set_ftrace_notrace files are open for read,
an iterator is created and sets its hash pointer to the associated hash that
represents filtering or notrace filtering to it. The issue is that the hash
it points to can change while the iteration is happening. All the locking
used to access the tracer's hashes are released which means those hashes can
change or even be freed. Using the hash pointed to by the iterator can cause
UAF bugs or similar.
Have the read of these files allocate and copy the corresponding hashes and
use that as that will keep them the same while the iterator is open. This
also simplifies the code as opening it for write already does an allocate
and copy, and now that the read is doing the same, there's no need to check
which way it was opened on the release of the file, and the iterator hash
can always be freed.
- Fix function graph to copy args into temp storage
The output of the function graph tracer shows both the entry and the exit of
a function. When the exit is right after the entry, it combines the two
events into one with the output of "function();", instead of showing:
function() {
}
In order to do this, the iterator descriptor that reads the events includes
storage that saves the entry event while it peaks at the next event in
the ring buffer. The peek can free the entry event so the iterator must
store the information to use it after the peek.
With the addition of function graph tracer recording the args, where the
args are a dynamic array in the entry event, the temp storage does not save
them. This causes the args to be corrupted or even cause a read of unsafe
memory.
Add space to save the args in the temp storage of the iterator.
- Fix race between ftrace_dump and reading trace_pipe
ftrace_dump() is used when a crash occurs where the ftrace buffer will be
printed to the console. But it can also be triggered by sysrq-z. If a
sysrq-z is triggered while a task is reading trace_pipe it can cause a race
in the ftrace_dump() where it checks if the buffer has content, then it
checks if the next event is available, and then prints the output
(regardless if the next event was available or not). Reading trace_pipe
at the same time can cause it to not be available, and this triggers a
WARN_ON in the print. Move the printing into the check if the next event
exists or not.

The first step maintaining the bus topology is to handle SelfIDComplete
event. This event occurs after initiating bus reset when 1394 OHCI link
layer is enabled, or when the bus topology changes (e.g. when a device is
added). Because enumeration of the selfID sequence can take some time, it
should be processed in a bottom half.
Currently, this is done in a module-local workqueue with the
WQ_MEM_RECLAIM flag, to allow invocation during memory reclaim paths. A
threaded IRQ handler is a preferable alternative, as it eliminates the
need to manage workqueue attributes manually.
Although SelfIDComplete events are not so frequent in normal usage,
handling them correctly is critical for proper bus topology management.
This commit switches SelfIDComplete handling to a threaded IRQ handler.

The value of OHCI1394_SelfIDCount register includes an error-indicating
bit. It is safer to place the tracepoint probe after validating the
register value.

Commit 74d6a5d566 ("9p/trans_fd: Fix concurrency del of req_list in
p9_fd_cancelled/p9_read_work") fixes a concurrency issue in the 9p filesystem
client where the req_list could be deleted simultaneously by both
p9_read_work and p9_fd_cancelled functions, but for the case where req->status
equals REQ_STATUS_RCVD.
Update the check for req->status in p9_fd_cancelled to skip processing not
just received requests, but anything that is not SENT, as whatever
changed the state from SENT also removed the request from its list.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

A buffer overflow vulnerability exists in the USB 9pfs transport layer
where inconsistent size validation between packet header parsing and
actual data copying allows a malicious USB host to overflow heap buffers.
The issue occurs because:
- usb9pfs_rx_header() validates only the declared size in packet header
- usb9pfs_rx_complete() uses req->actual (actual received bytes) for
memcpy
This allows an attacker to craft packets with small declared size
(bypassing validation) but large actual payload (triggering overflow
in memcpy).
Add validation in usb9pfs_rx_complete() to ensure req->actual does not
exceed the buffer capacity before copying data.

This is an extension of the last commit to cached mode as well. While
server-side changes when using cached mode is not expected, when it does
happen we can get things like -EOPNOTSUPP. With this change at least when
we realize the inode has updated (for example after a `touch` on the
client), we can get a new one.

Currently if another process keeps a file open, due to existing dentry in
the dcache, other processes will not see updated metadata of that file if
it is changed on the server, even in uncached mode.
This can also manifest as -ENODATA when reading a file that has shrunk on
the server (even if it's re-opened in another process), or -ENOTSUPP if
the file has changed type (e.g. regular file to directory) on the server.
We can end up in a situation where both `readdir` or `read` fails until
the file is closed by all processes using it.
This commit fixes that, and invalidates the dentry altogether if the inode
type is changed (for uncached mode).
