[ Upstream commit 9358bdb9f9 ]
The expression '1 << EraseUnitSize' is evaluated in int, which causes
a negative result when shifting by 31 - the upper bound of the valid
range [10, 31], enforced by scan_header(). This leads to incorrect
extension when storing the result in 'erase->len' (uint64_t), producing
a large unexpected value.

If ctx->steps is zero, the loop processing ECC steps is skipped,
and the variable ret remains uninitialized. It is later checked
and returned, which leads to undefined behavior and may cause
unpredictable results in user space or kernel crashes.
This scenario can be triggered in edge cases such as misconfigured
geometry, ECC engine misuse, or if ctx->steps is not validated
after initialization.
Initialize ret to zero before the loop to ensure correct and safe
behavior regardless of the ctx->steps value.

[ Upstream commit d15638bf76 ]
This reverts commit 98d1fb94ce.
The commit uses data nbits instead of addr nbits for dummy phase. This
causes a regression for all boards where spi-tx-bus-width is smaller
than spi-rx-bus-width. It is a common pattern for boards to have
spi-tx-bus-width == 1 and spi-rx-bus-width > 1. The regression causes
all reads with a dummy phase to become unavailable for such boards,
leading to a usually slower 0-dummy-cycle read being selected.
Most controllers' supports_op hooks call spi_mem_default_supports_op().
In spi_mem_default_supports_op(), spi_mem_check_buswidth() is called to
check if the buswidths for the op can actually be supported by the
board's wiring. This wiring information comes from (among other things)
the spi-{tx,rx}-bus-width DT properties. Based on these properties,
SPI_TX_* or SPI_RX_* flags are set by of_spi_parse_dt().
spi_mem_check_buswidth() then uses these flags to make the decision
whether an op can be supported by the board's wiring (in a way,
indirectly checking against spi-{rx,tx}-bus-width).
Now the tricky bit here is that spi_mem_check_buswidth() does:
if (op->dummy.nbytes &&
spi_check_buswidth_req(mem, op->dummy.buswidth, true))
return false;
The true argument to spi_check_buswidth_req() means the op is treated as
a TX op. For a board that has say 1-bit TX and 4-bit RX, a 4-bit dummy
TX is considered as unsupported, and the op gets rejected.
The commit being reverted uses the data buswidth for dummy buswidth. So
for reads, the RX buswidth gets used for the dummy phase, uncovering
this issue. In reality, a dummy phase is neither RX nor TX. As the name
suggests, these are just dummy cycles that send or receive no data, and
thus don't really need to have any buswidth at all.
Ideally, dummy phases should not be checked against the board's wiring
capabilities at all, and should only be sanity-checked for having a sane
buswidth value. Since we are now at rc7 and such a change might
introduce many unexpected bugs, revert the commit for now. It can be
sent out later along with the spi_mem_check_buswidth() fix.

commit b086a46dae upstream.
When two chip-selects are configured in the device tree, and the second is
a non-native GPIO, both the GPIO-based chip-select and the first native
chip-select may be asserted simultaneously. This double assertion causes
incorrect read and write operations.
The issue occurs because when nfc->ncs <= 2, nfc->spare_cs is always
initialized to 0 due to static initialization. Consequently, when the
second chip-select (GPIO-based) is selected in anfc_assert_cs(), it is
detected by anfc_is_gpio_cs(), and nfc->native_cs is assigned the value 0.
This results in both the GPIO-based chip-select being asserted and the
NAND controller register receiving 0, erroneously selecting the native
chip-select.
This patch resolves the issue, as confirmed by oscilloscope testing with
configurations involving two or more chip-selects in the device tree.

During wear-leveing work, the source PEB will be moved into scrub list
when source LEB cannot be locked in ubi_eba_copy_leb(), which is wrong
for non-scrub type source PEB. The problem could bring extra and
ineffective wear-leveing jobs, which makes more or less negative effects
for the life time of flash. Specifically, the process is divided 2 steps:
1. wear_leveling_worker // generate false scrub type PEB
ubi_eba_copy_leb // MOVE_RETRY is returned
leb_write_trylock // trylock failed
scrubbing = 1;
e1 is put into ubi->scrub
2. wear_leveling_worker // schedule false scrub type PEB for wl
scrubbing = 1
e1 = rb_entry(rb_first(&ubi->scrub))
The problem can be reproduced easily by running fsstress on a small
UBIFS partition(<64M, simulated by nandsim) for 5~10mins
(CONFIG_MTD_UBI_FASTMAP=y,CONFIG_MTD_UBI_WL_THRESHOLD=50). Following
message is shown:
ubi0: scrubbed PEB 66 (LEB 0:10), data moved to PEB 165
Since scrub type source PEB has set variable scrubbing as '1', and
variable scrubbing is checked before variable keep, so the problem can
be fixed by setting keep variable as 1 directly if the source LEB cannot
be locked.

The default dummy cycle for Macronix SPI NOR flash in Octal Output
Read Mode(1-1-8) is 20.
Currently, the dummy buswidth is set according to the address bus width.
In the 1-1-8 mode, this means the dummy buswidth is 1. When converting
dummy cycles to bytes, this results in 20 x 1 / 8 = 2 bytes, causing the
host to read data 4 cycles too early.
Since the protocol data buswidth is always greater than or equal to the
address buswidth. Setting the dummy buswidth to match the data buswidth
increases the likelihood that the dummy cycle-to-byte conversion will be
divisible, preventing the host from reading data prematurely.

Until recently the "upper layer" was MTD. But following incremental
reworks to bring spi-nand support and more recently generic ECC support,
there is now an intermediate "generic NAND" layer that also needs to get
access to some values. When using "converted" ECC engines, like the
software ones, these values are already propagated correctly. But
otherwise when using good old raw NAND controller drivers, we need to
manually set these values ourselves at the end of the "scan" operation,
once these values have been negotiated.
Without this propagation, later (generic) checks like the one warning
users that the ECC strength is not high enough might simply no longer
work.

I ran into a randconfig build failure with UBSAN using gcc-13.2:
arm-linux-gnueabi-ld: error: unplaced orphan section `.bss..Lubsan_data31' from `drivers/mtd/nand/raw/diskonchip.o'
I'm not entirely sure what is going on here, but I suspect this has something
to do with the check for the end of the doc_locations[] array that contains
an (unsigned long)0xffffffff element, which is compared against the signed
(int)0xffffffff. If this is the case, we should get a runtime check for
undefined behavior, but we instead get an unexpected build-time error.
I would have expected this to work fine on 32-bit architectures despite the
signed integer overflow, though on 64-bit architectures this likely won't
ever work.
Changing the contition to instead check for the size of the array makes the
code safe everywhere and avoids the ubsan check that leads to the link
error. The loop code goes back to before 2.6.12.
