A big core MTD change is the introduction of a new class to always
register a master device. This is a problem that has been there forever: the "master" device was not always present depending on a number of heuristics such as the presence of fixed partitions and the absence of a Kconfig symbol to force its presence. This was a problem for runtime PM operations which might not have the "master" device available in all situation. The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP table fixups for Macronix MX25L3255E have been merged. Aside from this, there is the usual load of misc improvement, fixes, and yaml conversion. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg91NEACgkQJWrqGEe9 VoR8egf+JPTtykQ+Bip9bHStgfpxi0+OKL81PUuPBsbs5C546u5t6ZRhoPsU+KqL ZTyUk3ys7HcSwZCuiS9V6ea6TNV1FvAVZm+ONpkuPnU60++z8YfVr8ZvtgT0IUXx COi+5ksdsTFZMyRG+VybRKnYNrTYB7j7CqVL8ifxq1XYWnYdhjy5PH4DgAKnBhGL 523kN2eR85AhvJ4aulsKbcqQQYKvJIQbhjAKklA3yQVarDmoOdiSmndoZlRy+MDu B9DaRMvRRa/g1nI0stvR9K7FtdSrMYTg4kowR9jPRx0zEZXFFsZbASgcC+3G7HdK 7rLFWrN+G6fitcEjeAnfyV+sKF48LA== =tW1t -----END PGP SIGNATURE----- Merge tag 'mtd/for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD updates from Miquel Raynal: "A big core MTD change is the introduction of a new class to always register a master device.

remoteproc updates for v6.16
Fix resource cleanup in the remoteproc attach error handling code paths. Refactor the various TI K3 drivers to extract and reuse common code between them. Add support in the i.MX remoteproc driver for determining from the firmware if Linux should wait on a "firmware ready" signal at startup. Improve the Xilinx R5F power down mechanism to handle use cases where this is shared with other entities in the system. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmg9xP0VHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3F/SEP/RgSiBNIMRYdBw/MT+FnSDv4kScE GvZZnW/FStjx+c+HIbTjMUjONWuDqBryx3FCVscp4OQKFXlfdd7OerVRPxaSvCzU QeB0Yi2ojnceUhh+t1AUC+27LO31h7sHzX/WpSLG2faUrq/p4vICSHiiS7LxVkmX s5KCJXCwnHEgfr2/g1yer/uo4KnNVxpAjRUPsYncWkAvDqCtTu8dA4wzCCeIvSGk kVZPVfPscKyP/YLxYUiwaNkxALjoAZS9sJ41eL76lic/GH3g8j96yFjOVhyiu0R4 f9eZ9ebHdFaF6kpBLuc+46govlw2ZhP/c6sivNcGYuKBRjoMI3UsQ3AvwuW3DE+D qiVbMlodRHuwbw/582NsMfe5+iskyBzyQkoiqJcit2kDTcKh5DDErH9Q72ceXzr3 hklgFFyIBmYVfLva807/0FiLKTJyJf9PVFy75BX/1m0MaoZeXyW/XohCqNgzlaW6 n0j1MqDP42+fayJjOuS2e7hu4W+CpUQNgD2Ec5U7kV8pUVPIWsowl6O135LU+T8T Wkw5tt/3rsJGSY3RE0oGHUdnEEqk/Bk8NWP1rfqZiMpKCDOtY+pVSfiWTkJgGNOR UqfC5f8GcGp0TYGAFmNA8svddP7Yq9ZUAlFKFTgeWHsLK1GbPHkr0XOK2RpKcfgs 99T869RX8nA9vx9k =GCF8 -----END PGP SIGNATURE----- Merge tag 'rproc-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: - Fix resource cleanup in the remoteproc attach error handling code paths - Refactor the various TI K3 drivers to extract and reuse common code between them - Add support in the i.MX remoteproc driver for determining from the firmware if Linux should wait on a "firmware ready" signal at startup - Improve the Xilinx R5F power down mechanism to handle use cases where this is shared with other entities in the system * tag 'rproc-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (46 commits) remoteproc: k3: Refactor release_tsp() functions into common driver remoteproc: k3: Refactor reserved_mem_init() functions into common driver remoteproc: k3: Refactor mem_release() functions into common driver remoteproc: k3: Refactor of_get_memories() functions into common driver remoteproc: k3: Refactor .da_to_va rproc ops into common driver remoteproc: k3: Refactor .get_loaded_rsc_table ops into common driver remoteproc: k3: Refactor .detach rproc ops into common driver remoteproc: k3: Refactor .attach rproc ops into common driver remoteproc: k3: Refactor .stop rproc ops into common driver remoteproc: k3: Refactor .start rproc ops into common driver remoteproc: k3: Refactor .unprepare rproc ops into common driver remoteproc: k3: Refactor .prepare rproc ops into common driver remoteproc: k3-dsp: Assert local reset during .prepare callback remoteproc: k3-dsp: Don't override rproc ops in IPC-only mode remoteproc: k3: Refactor rproc_request_mbox() implementations into common driver remoteproc: k3-m4: Ping the mbox while acquiring the channel remoteproc: k3: Refactor rproc_release() implementation into common driver remoteproc: k3-m4: Introduce central function to release rproc from reset remoteproc: k3-dsp: Correct Reset deassert logic for devices w/o lresets remoteproc: k3: Refactor rproc_reset() implementation into common driver ... |

While not yet in the tree, there is a proposed patch[1] that was
depending on the prior behavior of _DEFINE_FLEX, which did not have an
explicit initializer. Provide this via __DEFINE_FLEX now, which can also
have attributes applied (e.g. __uninitialized).

watchdog: iTCO_wdt: Update the heartbeat value after clamping timeout
When executing "modprobe iTCO_wdt heartbeat=700", the user-specified 'heartbeat' parameter exceeds the valid range, the driver clamps the timeout to default 30s but fails to update the logged 'heartbeat' value, resulting in misleading log output: iTCO_wdt iTCO_wdt: timeout value out of range, using 30 iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0) After validating the range, update the 'heartbeat' value with the clamped timeout value to ensure that log messages accurately reflect the actual runtime parameters.

At probe time, check if the watchdog is already started and then set WDOG_HW_RUNNING in the watchdog status.

The hardware only supports timeouts slightly below 3mins, but by using max_hw_heartbeat_ms we can let the kernel take care of supporting larger timeouts than that requested from userspace. Switching to max_hw_heartbeat_ms also means our set_timeout function now needs to configure the hardware to the minimum of either the requested timeout (in seconds) or the maximum supported by the user (in seconds).

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables".

require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible.

soc: devicetree updates for 6.16
There are 11 newly supported SoCs, but these are all either new
variants of existing designs, or straig reuses of the existing
chip in a new package:
- RK3562 is a new chip based on the old Cortex-A53 core, apparently
a low-cost version of the Cortex-A55 based RK3568/RK3566.
- NXP i.MX94 is a minor variation of i.MX93/i.MX95 with a different
set of on-chip peripherals.
- Renesas RZ/V2N (R9A09G056) is a new member of the larger RZ/V2 family
- Amlogic S6/S7/S7D
- Samsung Exynos7870 is an older chip similar to Exynos7885
- WonderMedia wm8950 is a minor variation on the wm8850 chip
- Amlogic s805y is almost idential to s805x
- Allwinner A523 is similar to A527 and T527
- Qualcomm MSM8926 is a variant of MSM8226
- Qualcomm Snapdragon X1P42100 is related to R1E80100
There are also 65 boards, including reference designs for the chips
above, this includes
- 12 new boards based on TI K3 series chips, most of them from
Toradex
- 10 devices using Rockchips RK35xx and PX30 chips
- 2 phones and 2 laptops based on Qualcomm Snapdragon designs
- 10 NXP i.MX8/i.MX9 boards, mostly for embedded/industrial uses
- 3 Samsung Galaxy phones based on Exynos7870
- 5 Allwinner based boards using a variety of ARMv8 chips
- 9 32-bit machines, each based on a different SoC family
Aside from the new hardware, there is the usual set of cleanups and
newly added hardware support on existing machines, for a total of 965
devicetree changesets.

low-cost version of the Cortex-A55 based RK3568/RK3566.
- NXP i.MX94 is a minor variation of i.MX93/i.MX95 with a different
set of on-chip peripherals.
- Renesas RZ/V2N (R9A09G056) is a new member of the larger RZ/V2
family
- Amlogic S6/S7/S7D
- Samsung Exynos7870 is an older chip similar to Exynos7885
- WonderMedia wm8950 is a minor variation on the wm8850 chip
- Amlogic s805y is almost idential to s805x
- Allwinner A523 is similar to A527 and T527
- Qualcomm MSM8926 is a variant of MSM8226
- Qualcomm Snapdragon X1P42100 is related to R1E80100
There are also 65 boards, including reference designs for the chips
above, this includes
- 12 new boards based on TI K3 series chips, most of them from
Toradex
- 10 devices using Rockchips RK35xx and PX30 chips
- 2 phones and 2 laptops based on Qualcomm Snapdragon designs
- 10 NXP i.MX8/i.MX9 boards, mostly for embedded/industrial uses
- 3 Samsung Galaxy phones based on Exynos7870
- 5 Allwinner based boards using a variety of ARMv8 chips
- 9 32-bit machines, each based on a different SoC family
Aside from the new hardware, there is the usual set of cleanups and
newly added hardware support on existing machines, for a total of 965
devicetree changesets"

ARM: soc updates for 6.16
The main update in size is the removal of the TI DaVinci DA830 SoC support. DA830 is similar to DA850, which remain supported, but only the reference board was ever supported, and we removed that one 3 years ago as it had never been converted to devicetree.

fbdev: Fix fb_set_var to prevent null-ptr-deref in fb_videomode_to_var
If fb_add_videomode() in fb_set_var() fails to allocate memory for
fb_videomode, later it may lead to a null-ptr dereference in
fb_videomode_to_var(), as the fb_info is registered while not having the
mode in modelist that is expected to be there, i.e. the one that is
described in fb_info->var.

The reason is that fb_info->var is being modified in fb_set_var(), and
then fb_videomode_to_var() is called. If it fails to add the mode to
fb_info->modelist, fb_set_var() returns error, but does not restore the
old value of fb_info->var. Restore fb_info->var on failure the same way
it is done earlier in the function.

Even though fbcon_init() checks beforehand if fb_match_mode() in
var_to_display() fails, it can not prevent the panic because fbcon_init()
does not return error code. Considering this and the comment in the code
about fb_match_mode() returning NULL - "This should not happen" - it is
better to prevent registering the fb_info if its mode was not set
successfully. Also move fb_add_videomode() closer to the beginning of
do_register_framebuffer() to avoid having to do the cleanup on fail.

fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod()
In fb_find_mode_cvt(), iff mode->refresh somehow happens to be 0x80000000,
cvt.f_refresh will become 0 when multiplying it by 2 due to overflow. It's
then passed to fb_cvt_hperiod(), where it's used as a divider -- division
by 0 will result in kernel oops. Add a sanity check for cvt.f_refresh to
avoid such overflow...

If con2fb_map contains a -1 things go wrong here. Instead, return NULL,
as callers of fbcon_info_from_console() are trying to compare against
existing "info" pointers, so error handling should kick in correctly.

==================================================================
By analyzing the vmcore, we found that vc->vc_origin was somehow placed
one line prior to vc->vc_screenbuf when vc was in KD_TEXT mode, and
further writings to /dev/vcs caused out-of-bounds reads (and writes
right after) in vcs_write_buf_noattr().
Our further experiments show that in most cases, vc->vc_origin equals to
vga_vram_base when the console is in KD_TEXT mode, and it's around
vc->vc_screenbuf for the KD_GRAPHICS mode. But via triggerring a
TIOCL_SETVESABLANK ioctl beforehand, we can make vc->vc_origin be around
vc->vc_screenbuf while the console is in KD_TEXT mode, and then by
writing the special 'ESC M' control sequence to the tty certain times
(depends on the value of `vc->state.y - vc->vc_top`), we can eventually
move vc->vc_origin prior to vc->vc_screenbuf. Here's the PoC, tested on
QEMU:
```
int main() {
const int RI_NUM = 10; // should be greater than `vc->state.y - vc->vc_top`
int tty_fd, vcs_fd;
const char *tty_path = "/dev/tty0";
const char *vcs_path = "/dev/vcs";
const char escape_seq[] = "\x1bM"; // ESC + M
const char trigger_seq[] = "Let's trigger an OOB write.";
struct vt_sizes vt_size = { 70, 2 };
int blank = TIOCL_BLANKSCREEN;
tty_fd = open(tty_path, O_RDWR);
char vesa_mode[] = { TIOCL_SETVESABLANK, 1 };
ioctl(tty_fd, TIOCLINUX, vesa_mode);
ioctl(tty_fd, TIOCLINUX, &blank);
ioctl(tty_fd, VT_RESIZE, &vt_size);
for (int i = 0; i < RI_NUM; ++i)
write(tty_fd, escape_seq, sizeof(escape_seq) - 1);
vcs_fd = open(vcs_path, O_RDWR);
write(vcs_fd, trigger_seq, sizeof(trigger_seq));
close(vcs_fd);
close(tty_fd);
return 0;
}
```
To solve this problem, add an address range validation check in
vgacon_scroll(), ensuring vc->vc_origin never precedes vc_screenbuf.

fbdev: arkfb: Cast ics5342_init() allocation type
In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct dac_info *" but the returned type will be "struct ics5342_info *", which has a larger allocation size. This is by design, as struct ics5342_info contains struct dac_info as its first member.
