[ Upstream commit fdf2e821052958a114618a95ab18a300d0b080cb ]
When erased subpages are read then the BCH decoder returns STATUS_ERASED
if they are all empty, or STATUS_UNCORRECTABLE if there are bitflips.
When there are bitflips, we have to set these bits again to show the
upper layers a completely erased page. When a bitflip happens in the
exact byte where the bad block marker is, then this byte is swapped
with another byte in block_mark_swapping(). The correction code then
detects a bitflip in another subpage and no longer corrects the bitflip
where it really happens.
Correct this behaviour by calling block_mark_swapping() after the
bitflips have been corrected.
In our case UBIFS failed with this bug because it expects erased
pages to be really empty:
UBIFS error (pid 187): ubifs_scan: corrupt empty space at LEB 36:118735
UBIFS error (pid 187): ubifs_scanned_corruption: corruption at LEB 36:118735

commit f5f92b36fbbb8ac7d70ff5fa39ec2637cce3094c upstream.
MTD allows compile-time configuration of the possible CFI geometry
settings that are allowed by the kernel, but that includes a couple of
invalid configurations, where no bank width or no interleave setting
is allowed. These are then caught with a compile-time warning:
include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.
include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected. No NOR chip support can work"
This is a bit annoying for randconfig tests, and can be avoided if
we change the Kconfig logic to always select the simplest configuration
when no other one is enabled.

commit 1873315fb156cbc8e46f28e8b128f17ff6c31728 upstream.
By convention, the FIFO address we pass using dmaengine_slave_config
is a physical address in the form that is understood by the DMA
engine, as a dma_addr_t, phys_addr_t or resource_size_t.
The sh_flctl driver however passes a virtual __iomem address that
gets cast to dma_addr_t in the slave driver. This happens to work
on shmobile because that platform sets up an identity mapping for
its MMIO regions, but such code is not portable to other platforms,
and prevents us from ever changing the platform mapping or reusing
the driver on other architectures like ARM64 that might not have the
mapping.
We also get a warning about a type mismatch for the case that
dma_addr_t is wider than a pointer, i.e. when CONFIG_LPAE is set:
drivers/mtd/nand/sh_flctl.c: In function 'flctl_setup_dma':
drivers/mtd/nand/sh_flctl.c:163:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
cfg.dst_addr = (dma_addr_t)FLDTFIFO(flctl);
This changes the driver to instead pass the physical address of
the FIFO that is extracted from the MMIO resource, making the
code more portable and avoiding the warning.

commit e4106a7c8236eb7b91686d36f3bf33ee43db94b4 upstream.
Add __init attribute on functions that are only called from other __init
functions and that are not inlined, at least with gcc version 4.8.4 on an
x86 machine with allyesconfig. Currently, the functions are put in the
.text.unlikely segment. Declaring them as __init will cause them to be
put in the .init.text and to disappear after initialization.
The result of objdump -x on the functions before the change is as follows:
00000000000001bc l F .text.unlikely 00000000000006a2 ck804xrom_init_one.isra.1
00000000000001aa l F .text.unlikely 0000000000000764 esb2rom_init_one.isra.1
00000000000001db l F .text.unlikely 0000000000000716 ichxrom_init_one.isra.1
And after the change it is as follows:
0000000000000000 l F .init.text 000000000000069d ck804xrom_init_one.isra.1
0000000000000000 l F .init.text 000000000000075f esb2rom_init_one.isra.1
0000000000000000 l F .init.text 0000000000000711 ichxrom_init_one.isra.1
Done with the help of Coccinelle. The semantic patch checks for local
static non-init functions that are called from an __init function and are
not called from any other function.
Note that in each case, the function is stored in the probe field of a
pci_driver structure, but this code is under an #if 0. The #if 0s have
been unchanged since 2009 at the latest.

commit e70dda0868fad0f74c46df21f7f45fec24f29879 upstream.
pci_read_config_word() might fail and not initialize its output,
as pointed out by older versions of gcc when using the -Wmaybe-unintialized
flag:
drivers/mtd/maps/ichxrom.c: In function ‘ichxrom_cleanup’:
drivers/mtd/maps/ichxrom.c:63:2: error: ‘word’ is used uninitialized in this function [-Werror=uninitialized]
This is apparently a correct warning, though it does not show up
with newer compilers. Changing the code to not attempt to write
back uninitialized data into PCI config space is a correct
fix for the problem and avoids the warning.

commit 7f29ae9f977bcdc3654e68bc36d170223c52fd48 upstream.
This fixes a race with idr_alloc where gd->first_minor can be set to the
same value for two simultaneous calls to ubiblock_create. Each instance
calls device_add_disk with the same first_minor. device_add_disk calls
bdi_register_owner which generates several warnings.

commit f4c6cd1a7f2275d5bc0e494b21fff26f8dde80f0 upstream.
When the requested ECC strength does not exactly match the strengths
supported by the ECC engine, the driver is selecting the closest
strength meeting the 'selected_strength > requested_strength'
constraint. Fix the fact that, in this particular case, ecc->strength
value was not updated to match the 'selected_strength'.
For instance, one can encounter this issue when no ECC requirement is
filled in the device tree while the NAND chip minimum requirement is not
a strength/step_size combo natively supported by the ECC engine.

commit 87e89ce8d0d14f573c068c61bec2117751fb5103 upstream.
Starting from commit 041e4575f034 ("mtd: nand: handle ECC errors in
OOB"), nand_do_read_oob() (from the NAND core) did return 0 or a
negative error, and the MTD layer expected it.
However, the trend for the NAND layer is now to return an error or a
positive number of bitflips. Deciding which status to return to the user
belongs to the MTD layer.
Commit e47f68587b82 ("mtd: check for max_bitflips in mtd_read_oob()")
brought this logic to the mtd_read_oob() function while the return value
coming from nand_do_read_oob() (called by the ->_read_oob() hook) was
left unchanged.

commit 30863e38ebeb500a31cecee8096fb5002677dd9b upstream.
When mtdoops calls mtd_panic_write(), it eventually calls
panic_nand_write() in nand_base.c. In order to properly wait for the
nand chip to be ready in panic_nand_wait(), the chip must first be
selected.
When using the atmel nand flash controller, a panic would occur due to
a NULL pointer exception.

commit 807c16253319ee6ccf8873ae64f070f7eb532cd5 upstream.
With the S25FL127S nor flash part, each writing to the configuration
register takes hundreds of ms. During that time, no more accesses to
the flash should be done (even reads).
This commit adds a wait loop after the register writing until the flash
finishes its work.
This issue could make rootfs mounting fail when the latter was done too
much closely to this quad enable bit setting step. And in this case, a
driver as UBIFS may try to recover the filesystem and may broke it
completely.

commit fddcca5107051adf9e4481d2a79ae0616577fd2c upstream.
When map_word gets too large, we use a lot of kernel stack, and for
MTD_MAP_BANK_WIDTH_32, this means we use more than the recommended
1024 bytes in a number of functions:
drivers/mtd/chips/cfi_cmdset_0020.c: In function 'cfi_staa_write_buffers':
drivers/mtd/chips/cfi_cmdset_0020.c:651:1: warning: the frame size of 1336 bytes is larger than 1024 bytes [-Wframe-larger-than=]
drivers/mtd/chips/cfi_cmdset_0020.c: In function 'cfi_staa_erase_varsize':
drivers/mtd/chips/cfi_cmdset_0020.c:972:1: warning: the frame size of 1208 bytes is larger than 1024 bytes [-Wframe-larger-than=]
drivers/mtd/chips/cfi_cmdset_0001.c: In function 'do_write_buffer':
drivers/mtd/chips/cfi_cmdset_0001.c:1835:1: warning: the frame size of 1240 bytes is larger than 1024 bytes [-Wframe-larger-than=]
This can be avoided if all operations on the map word are done
indirectly and the stack gets reused between the calls. We can
mostly achieve this by selecting MTD_COMPLEX_MAPPINGS whenever
MTD_MAP_BANK_WIDTH_32 is set, but for the case that no other
bank width is enabled, we also need to use a non-constant
map_bankwidth() to convince the compiler to use less stack.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[Brian: this patch mostly achieves its goal by forcing
MTD_COMPLEX_MAPPINGS (and the accompanying indirection) for 256-bit
mappings; the rest of the change is mostly a wash, though it helps
reduce stack size slightly. If we really care about supporting
256-bit mappings though, we should consider rewriting some of this
code to avoid keeping and assigning so many 256-bit objects on the
stack.]

commit 9cd9a21ce070be8a918ffd3381468315a7a76ba6 upstream.
In commit 6afaf8a484cb ("UBI: flush wl before clearing update marker") I
managed to trigger and fix a similar bug. Now here is another version of
which I assumed it wouldn't matter back then but it turns out UBI has a
check for it and will error out like this:
|ubi0 warning: validate_vid_hdr: inconsistent used_ebs
|ubi0 error: validate_vid_hdr: inconsistent VID header at PEB 592
All you need to trigger this is? "ubiupdatevol /dev/ubi0_0 file" + a
powercut in the middle of the operation.
ubi_start_update() sets the update-marker and puts all EBs on the erase
list. After that userland can proceed to write new data while the old EB
aren't erased completely. A powercut at this point is usually not that
much of a tragedy. UBI won't give read access to the static volume
because it has the update marker. It will most likely set the corrupted
flag because it misses some EBs.
So we are all good. Unless the size of the image that has been written
differs from the old image in the magnitude of at least one EB. In that
case UBI will find two different values for `used_ebs' and refuse to
attach the image with the error message mentioned above.
So in order not to get in the situation, the patch will ensure that we
wait until everything is removed before it tries to write any data.
The alternative would be to detect such a case and remove all EBs at the
attached time after we processed the volume-table and see the
update-marker set. The patch looks bigger and I doubt it is worth it
since usually the write() will wait from time to time for a new EB since
usually there not that many spare EB that can be used.

commit bd5d21310133921021d78995ad6346f908483124 upstream.
After parsing TRX we should skip to the first block placed behind it.
Our code was working only with TRX with length not aligned to the
blocksize. In other cases (length aligned) it was missing the block
places right after TRX.
This fixes calculation and simplifies the comment.

commit 73529c872a189c747bdb528ce9b85b67b0e28dec upstream.
The xway_nand driver accesses the ltq_ebu_membase symbol which is not
exported. This also should not get exported and we should handle the
EBU interface in a better way later. This quick fix just deactivated
support for building as module.

Commit e96a8a3bb671 ("UBI: Fastmap: Do not add vol if it already
exists") introduced a bug by changing the possible error codes returned
by add_vol():
- this function no longer returns NULL in case of allocation failure
but return ERR_PTR(-ENOMEM)
- when a duplicate entry in the volume RB tree is found it returns
ERR_PTR(-EEXIST) instead of ERR_PTR(-EINVAL)
Fix the tests done on add_vol() return val to match this new behavior.

commit 2365418879e9abf12ea9def7f9f3caf0dfa7ffb0 upstream.
When Fastmap is used we can face here an -EBADMSG
since Fastmap cannot know about unmaps.
If the erasure was interrupted the PEB may show ECC
errors and UBI would go to ro-mode as it assumes
that the PEB was check during attach time, which is
not the case with Fastmap.

commit f6d7c1b5598b6407c3f1da795dd54acf99c1990c upstream.
This fixes subpage writes when using 4-bit HW ECC.
There has been numerous reports about ECC errors with devices using this
driver for a while. Also the 4-bit ECC has been reported as broken with
subpages in [1] and with 16 bits NANDs in the driver and in mach* board
files both in mainline and in the vendor BSPs.
What I saw with 4-bit ECC on a 16bits NAND (on an LCDK) which got me to
try reinitializing the ECC engine:
- R/W on whole pages properly generates/checks RS code
- try writing the 1st subpage only of a blank page, the subpage is well
written and the RS code properly generated, re-reading the same page
the HW detects some ECC error, reading the same page again no ECC
error is detected
Note that the ECC engine is already reinitialized in the 1-bit case.
Tested on my LCDK with UBI+UBIFS using subpages.
This could potentially get rid of the issue workarounded in [1].

commit 79ad07d45743721010e766e65dc004ad249bd429 upstream.
There is a cut and paste issue here. The bug is that we are allocating
more memory than necessary for msp_maps. We should be allocating enough
space for a map_info struct (144 bytes) but we instead allocate enough
for an mtd_info struct (1840 bytes). It's a small waste.
The other part of this is not harmful but when we allocated msp_flash
then we allocated enough space fro a map_info pointer instead of an
mtd_info pointer. But since pointers are the same size it works out
fine.
Anyway, I decided to clean up all three allocations a bit to make them
a bit more consistent and clear.
