Loading files stored with lzo compression from a btrfs filesystem was producing unaligned memory accesses, which were causing a data abort and a reset on an Orange Pi Zero.

2017-10-16jffs2: ECC corrected nand data is ignoredEngling, Uwe
Hello, I ran into a problem with the JFFS2 filesystem driver implemented in U-Boot. I've got a NAND device that has correctable ECC errors (corrected somewhere in mtd/nand/nand_base.c). The NAND driver tells the filesystem layer (jffs2_1pass.c) above that there occurred correctable ECC errors and returns with a "value > 0". The JFFS2 driver recognizes the corrected ECC errors as real error and skips this block because the only accepts a "return value == 0" as correct. This problem exists for over 8 years (I checked version 2010.09) so I'm a little bit worried that I interpreted something wrong or didn't get the whole context. Can someone confirm this bug (and the bugfix) in the u-boot jffs2 driver? There was a mail in 2012 that mentioned the same problem, but there was no patch: http://u-boot.10912.n7.nabble.com/JFFS2-seems-to-drop-nand-data-with-ECC-corrections-td142008.html Sometime after this discussion the return value of nand_read() changed from -EUCLEAN as correctable ECC error to a positive value with the count of ECC corrected errors. With kind reguards, Uwe Engling

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

If you attempted to write a file smaller than cur_part_info.start blocks on a full partition the old calculation fails to catch the overflow. This would cause an infinite loop in the determine_fatent function.
