When calling smb2_ioctl_query_info() with invalid
smb_query_info::flags, a NULL ptr dereference is triggered when trying
to kfree() uninitialised rqst[n].rq_iov array.
This also fixes leaked paths that are created in SMB2_open_init()
which required SMB2_open_free() to properly free them.
Here is a small C reproducer that triggers it
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#define die(s) perror(s), exit(1)
#define QUERY_INFO 0xc018cf07
int main(int argc, char *argv[])
{
int fd;
if (argc < 2)
exit(1);
fd = open(argv[1], O_RDONLY);
if (fd == -1)
die("open");
if (ioctl(fd, QUERY_INFO, (uint32_t[]) { 0, 0, 0, 4, 0, 0}) == -1)
die("ioctl");
close(fd);
return 0;
}

When calling smb2_ioctl_query_info() with
smb_query_info::flags=PASSTHRU_FSCTL and
smb_query_info::output_buffer_length=0, the following would return
0x10
buffer = memdup_user(arg + sizeof(struct smb_query_info),
qi.output_buffer_length);
if (IS_ERR(buffer)) {
kfree(vars);
return PTR_ERR(buffer);
}
rather than a valid pointer thus making IS_ERR() check fail. This
would then cause a NULL ptr deference in @buffer when accessing it
later in smb2_ioctl_query_ioctl(). While at it, prevent having a
@buffer smaller than 8 bytes to correctly handle SMB2_SET_INFO
FileEndOfFileInformation requests when
smb_query_info::flags=PASSTHRU_SET_INFO.
Here is a small C reproducer which triggers a NULL ptr in @buffer when
passing an invalid smb_query_info::flags

smbfs_common
Fix an endian bug in ksmbd for one remaining use of
Persistent/VolatileFid that unnecessarily converted it (it is an
opaque endian field that does not need to be and should not
be converted) in oplock_break for ksmbd, and move the definitions
for the oplock and lease break protocol requests and responses
to fs/smbfs_common/smb2pdu.h
Also move a few more definitions for various protocol requests
that were duplicated (in fs/cifs/smb2pdu.h and fs/ksmbd/smb2pdu.h)
into fs/smbfs_common/smb2pdu.h including:
- various ioctls and reparse structures
- validate negotiate request and response structs
- duplicate extents structs

When 'index' is a big numbers, it may become negative which forced
to 'int'. then 'index << part_shift' might overflow to a positive
value that is not greater than '0xfffff', then sysfs might complains
about duplicate creation. Because of this, move the 'index' judgment
to the front will fix it and be better.

Convert the encoders to bridge drivers in order to standardize on
a single API with built-in dumb encoder support for compatibility
with existing component drivers.
Driver bridge conversion will help to reuse the same bridge on
different platforms as exynos dsi driver can be used as a Samsung
DSIM and use it for i.MX8MM platform.
Bridge conversion,
- Drops drm_encoder_helper_funcs.
- Adds drm_bridge_funcs and register a drm bridge.
- Drops bridge_chain.
- Separate pre_enable from enable function.
- Separate post_disable from disable function.
Convert it.

Replace the manual panel handling code by a drm panel_bridge via
devm_drm_of_get_bridge().
Adding panel_bridge handling,
- Drops drm_connector and related operations as drm_bridge_attach
creates connector during attachment.
- Drops panel pointer and iterate the bridge, so-that it can operate
the normal bridge and panel_bridge in constitutive callbacks.
This simplifies the driver and allows all components in the display
pipeline to be treated as bridges.

MIC drivers in the Exynos5433 display pipeline are already registered
as bridge drivers and it is more advisable to attach the downstream
bridge on the bridge attach call instead of doing the same in the
DSI driver.
This makes bridge attachment more meaningful and avoids the races
during bridge function calls.
So, move the bridge finding and drm_bridge_attach from DSI to MIC.

BUG observed in exynos dsi driver where drm_bridge_attach is trying to

So reset the atomic state for a given connector by freeing the state pointer

This patch calls the connector->funcs->reset in panel_bridge_attach.

The TC358767/TC358867/TC9595 are all capable of operating in multiple
modes, DPI-to-(e)DP, DSI-to-(e)DP, DSI-to-DPI. Add support for the
DSI-to-DPI mode.
This requires skipping most of the (e)DP initialization code, which is
currently a large part of this driver, hence it is better to have far
simpler separate tc_dpi_bridge_funcs and their implementation.
The configuration of DPI output is also much simpler. The configuration
of the DSI input is rather similar to the other TC bridge chips.
The Pixel PLL in DPI output mode does not have the 65..150 MHz limitation
imposed on the (e)DP output mode, so this limitation is skipped to permit
operating panels with far slower pixel clock, even below 9 MHz. This mode
of operation of the PLL is valid and tested.
The detection of bridge mode is now added into tc_probe_bridge_mode(),
where in case a DPI panel is found on port@1 endpoint@1, the mode is
assumed to be DSI-to-DPI. If (e)DP is detected on port@2, the mode is
assumed to be DPI-to-(e)DP.
The DSI-to-(e)DP mode is not supported due to lack of proper hardware,
but this would be some sort of mix between the two aforementioned modes.

__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings. Also, error return codes don't mean anything to
obsolete_checksetup() -- only non-zero (usually 1) or zero.
So return 1 from jive_mtdset().

When splitting a value entry, we may need to add the new nodes to the LRU
list and remove the parent node from the LRU list. The WARN_ON checks
in shadow_lru_isolate() catch this oversight. This bug was latent
until we stopped splitting folios in shrink_page_list() with commit
820c4e2e6f51 ("mm/vmscan: Free non-shmem folios without splitting them").
That allows the creation of large shadow entries, and subsequently when
trying to page in a small page, we will split the large shadow entry
in __filemap_add_folio().

macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

The rxrpc_call struct has a timer used to handle various timed events
relating to a call. This timer can get started from the packet input
routines that are run in softirq mode with just the RCU read lock held.
Unfortunately, because only the RCU read lock is held - and neither ref or
other lock is taken - the call can start getting destroyed at the same time
a packet comes in addressed to that call. This causes the timer - which
was already stopped - to get restarted. Later, the timer dispatch code may
then oops if the timer got deallocated first.
Fix this by trying to take a ref on the rxrpc_call struct and, if
successful, passing that ref along to the timer. If the timer was already
running, the ref is discarded.
The timer completion routine can then pass the ref along to the call's work
item when it queues it. If the timer or work item where already
queued/running, the extra ref is discarded.

The invalid EDID block filtering uses the number of valid EDID
extensions instead of all EDID extensions for looping the extensions in
the copy. This is fine, by coincidence, if all the invalid blocks are at
the end of the EDID. However, it's completely broken if there are
invalid extensions in the middle; the invalid blocks are included and
valid blocks are excluded.
Fix it by modifying the base block after, not before, the copy.

Currently, the debugfs mechanism is that all functions share a
global variable to save the pointer for obtaining data. When
different functions concurrently access the same file node,
repeated release exceptions occur. Therefore, the granularity
of the pointer for storing the obtained data is adjusted to be
private for each function.

docs: update and move the netdev-FAQ
A section of documentation for tree-specific process quirks had
been created a while back. There's only one tree in it, so far,
the tip tree, but the contents seem to answer similar questions
as we answer in the netdev-FAQ. Move the netdev-FAQ.
Take this opportunity to touch up and update a few sections.
v3: remove some confrontational? language from patch 7
v2: remove non-git in patch 3
add patch 5

We want people to mark their patches with net and net-next in the subject.
Many miss doing that. Move the FAQ section which points that out up, and
place it after the section which enumerates the trees, that seems like
a pretty logical place for it. Since the two sections are together we
can remove a little bit (not too much) of the repetition.
v2: also remove the text for non-git setups, we want people to use git.
