2012-01-09mtd: docg3: add fast modeRobert Jarzmik
Docg3 chips can work in 3 modes : normal MLC mode, fast mode and reliable mode. Normally, as docg3 is a MLC chip, it should be configured to work in normal mode. In both normal mode, each page is distinct. This means that writing to page 12 of blocks 14,15 writes only to that page, and reading from page 12 of blocks 14,15 reads only from that page. In reliable and fast modes, pages are coupled by pairs, and are clones one of each other. This means that the available capacity of the chip is halved. Pages are coupled in each block, and page of index 2*n contains the same data as page 2*n+1 of the same block. In fast mode, the reads occur a bit faster, but are a bit less reliable that in normal mode. When reading from page 2*n, the chip reads bytes from both page 2*n and page 2*n+1, makes a logical and for each byte, and returns the result. As programming a page means "clearing bits", even if a bit was not cleared on one page because the flash is worn out, the other page has the bit cleared, and the result of the "AND" gives a correct result. When writing to page 2*n, the chip writes data to both page 2*n and page 2*n+1.

Fix the docg3 reads to be able to cope with all possible data buffer / oob buffer / file mode combinations from docg3_read_oob(). This especially ensures that raw reads do not use ECC corrections, and AUTOOOB and PLACEOOB do use ECC correction. The approach is to empty docg3_read() and make it a wrapper to docg3_read_oob(). As docg3_read_oob() handles all the funny cases (no data buffer but oob buffer, data buffer but no oob buffer, ...), docg3_read() is just a special use of docg3_read_oob().

2012-01-09mtd: mtd_blkdevs: don't increase 'open' count on error pathBrian Norris
Some error paths in mtd_blkdevs were fixed in the following commit: commit 94735ec4044a6d318b83ad3c5794e931ed168d10 mtd: mtd_blkdevs: fix error path in blktrans_open But on these error paths, the block device's `dev->open' count is already incremented before we check for errors. This meant that, while the error path was handled correctly on the first time through blktrans_open(), the device is erroneously considered already open on the second time through. This problem can be seen, for instance, when a UBI volume is simultaneously mounted as a UBIFS partition and read through its corresponding gluebi mtdblockX device. This results in blktrans_open() passing its error checks (with `dev->open > 0') without actually having a handle on the device. Here's a summarized log of the actions and results with nandsim: # modprobe nandsim # modprobe mtdblock # modprobe gluebi # modprobe ubifs # ubiattach /dev/ubi_ctrl -m 0 ... # ubimkvol /dev/ubi0 -N test -s 16MiB ... # mount -t ubifs ubi0:test /mnt # ls /dev/mtdblock* /dev/mtdblock0 /dev/mtdblock1 # cat /dev/mtdblock1 > /dev/null cat: can't open '/dev/mtdblock4': Device or resource busy # cat /dev/mtdblock1 > /dev/null CPU 0 Unable to handle kernel paging request at virtual address fffffff0, epc == 8031536c, ra == 8031f280 Oops[#1]: ...

2011-12-23netfilter: xt_connbytes: handle negation correctlyFlorian Westphal
"! --connbytes 23:42" should match if the packet/byte count is not in range. As there is no explict "invert match" toggle in the match structure, userspace swaps the from and to arguments (i.e., as if "--connbytes 42:23" were given). However, "what <= 23 && what >= 42" will always be false. Change things so we use "||" in case "from" is larger than "to". This change may look like it breaks backwards compatibility when "to" is 0. However, older iptables binaries will refuse "connbytes 42:0", and current releases treat it to mean "! --connbytes 0:42", so we should be fine.
