2014-08-19mtd: gpio_flash: handle case where offset + len exceeds the window sizeAaron Wu1-14/+28
Fix the bug in handling gpio flash read/write when offset + len from MTD exceeds the window size Signed-off-by: Aaron Wu <[email protected]> [Brian: made some commentary edits. Also note that the BUG_ON() was provably false for all non-negative inputs (since x % y <= x), so we dropped it.] Signed-off-by: Brian Norris <[email protected]>
2014-08-19mtd: nand: Use ULL-suffix for big u64 constantGeert Uytterhoeven1-1/+1
drivers/mtd/nand/nand_timings.c:45: warning: integer constant is too large for ‘long’ type [ Editorial note: This is a false warning. Looking at ISO draft N1124 (this is approximately C11, the first PDF I had lying around), section 6.4.4.1 (statement 5): "The type of an integer constant is the first of the corresponding list in which its value can be represented." So this should not be an overflow, and any toolchain that says so (e.g., GCC 4.4) is buggy. -Brian ] Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Brian Norris <[email protected]>
2014-08-19mtd: atmel_nand: NFC: fix mtd_nandbiterrs.ko test fail when using sram writeWu, Josh1-8/+9
When enable NFC sram write, it will failed the mtd_nandbiterrs.ko test. As in driver's nfc_sram_write_page(), if ops->mode equal to MTD_OSP_RAW, driver assumes the data buffer contains one page data and one oob data followed. And driver will write the page data and oob data to nand. But this is wrong implementation. Since the data buffer don't contains the oob data to write. We should write the chip->oob_poi to nand's oob. So this patch fix it by writing the oob data from chip->oob_poi.

2014-08-19mtd: nand: fix integer widening problemsBrian Norris1-2/+2
chip->pagebuf is a 32-bit type (int), so the shift will only be applied as 32-bit. Fix this for 64-bit safety. Caught by Coverity. Signed-off-by: Brian Norris <[email protected]>

2014-08-19mtd: nand: denali: set proper error code on timeoutBrian Norris1-3/+1
The condition "if (irq_status == 0)" already ensures that one half of the ternary ?: is dead. I think this should probably actually be a FAIL, not a PASS. Caught by Coverity. Signed-off-by: Brian Norris <[email protected]> Cc: Jamie Iles <[email protected]>

2014-08-19mtd: tests: fix integer overflow issuesBrian Norris7-22/+22
These multiplications are done with 32-bit arithmetic, then converted to 64-bit. We should widen the integers first to prevent overflow. This could be a problem for large (>4GB) MTD's. Detected by Coverity. Signed-off-by: Brian Norris <[email protected]> Cc: Akinobu Mita <[email protected]>

2014-08-19mtd: remove dead non-char logicBrian Norris1-8/+5
MTD used to allow compiling out character device support. This was dropped in the following commit, but some of the accompanying logic was never dropped: commit 660685d9d1b4730f0b5ca97fa95f272f99c63bce Author: Artem Bityutskiy <[email protected]> Date: Thu Mar 14 13:27:40 2013 +0200 mtd: merge mtdchar module with mtdcore The weird logic was flagged by Coverity.

2014-08-19mtd: sm_ftl: initialize error codeBrian Norris1-1/+1
There is one theoretical case that could fall through to using an uninitialized value as the return code. Let's give it a value of 0. Untested. Caught by Coverity. Signed-off-by: Brian Norris <[email protected]>
2014-08-19mtd: correct upper bounds check for mtd_*() APIsBrian Norris1-13/+13
When checking the upper boundary (i.e., whether an address is higher than the maximum size of the MTD), we should be doing an inclusive check (greater or equal). For instance, an address of 16MB (0x1000000) on a 16MB device is invalid. The strengthening of this bounds check is redundant for those which already have a address+length check and ensure that the length is non-zero, but let's just fix them all, for completeness.

2014-08-19mtd: cfi_cmdset_0002: allow retry/timeout loop to exitBrian Norris1-0/+2
The variable 'retries' is never modified, so if the reset operation never is going to complete, we'll get stuck in an infinite loop. It looks like the intention was to decrement 'retries' on every loop. Untested. Caught by Coverity. Signed-off-by: Brian Norris <[email protected]>
2014-08-19mtd: nand: fix nand_lock/unlock() functionWhite Ding1-0/+18
Do nand reset before write protect check. If we want to check the WP# low or high through STATUS READ and check bit 7, we must reset the device, other operation (eg.erase/program a locked block) can also clear the bit 7 of status register. As we know the status register can be refreshed, if we do some operation to trigger it, for example if we do erase/program operation to one block that is locked, then READ STATUS, the bit 7 of READ STATUS will be 0 indicate the device in write protect, then if we do erase/program operation to another block that is unlocked, the bit 7 of READ STATUS will be 1 indicate the device is not write protect. Suppose we checked the bit 7 of READ STATUS is 0 then judge the WP# is low (write protect), but in this case the WP# maybe high if we do erase/program operation to a locked block, so we must reset the device if we want to check the WP# low or high through STATUS READ and check bit 7.

2014-08-19mtd: Fixed checkpatch seq_printf warningsSamarth Parikh2-15/+15
Fixed checkpatch warnings: "WARNING: Prefer seq_puts to seq_printf" This patch is created with reference to the ongoing lkml thread https://lkml.org/lkml/2014/7/15/646 where Andrew Morton wrote: " - puts is presumably faster - puts doesn't go rogue if you accidentally pass it a "%". - this patch would actually make compiled object files few bytes smaller.
