ubifs: fix snprintf() checking

2021-06-18T20:04:47+00:00

The snprintf() function returns the number of characters (not counting the NUL terminator) that it would have printed if we had space. This buffer has UBIFS_DFS_DIR_LEN characters plus one extra for the terminator. Printing UBIFS_DFS_DIR_LEN is okay but anything higher will result in truncation. Thus the comparison needs to be change from == to >. These strings are compile time constants so this patch doesn't affect runtime.

ubi: Do not zero out EC and VID on ECC-ed NOR flashes

2020-12-13T20:57:21+00:00

For NOR flashes EC and VID are zeroed out before an erase is issued to make sure UBI does not mistakenly treat the PEB as used and associate it with an LEB. But on some flashes, like the Cypress Semper S28 SPI NOR flash family, multi-pass page programming is not allowed on the default ECC scheme. This means zeroing out these magic numbers will result in the flash throwing a page programming error. Do not zero out EC and VID for such flashes. A writesize > 1 is an indication of an ECC-ed flash. Signed-off-by: Pratyush Yadav Reviewed-by: Tudor Ambarus Signed-off-by: Richard Weinberger
