u-boot.git/fs/ext4/ext4_write.c, branch v2014.01 Unnamed repository; edit this file 'description' to name the repository. fs/ext4: fix calling put_ext4 with truncated offset 2014-01-20T15:09:38+00:00 Ma Haijun mahaijuns@gmail.com 2014-01-08T00:15:33+00:00 0550870b1c590be6beb09b57762ec43b5516f7d1 Curently, we are using 32 bit multiplication to calculate the offset, so the result will always be 32 bit. This can silently cause file system corruption when performing a write operation on partition larger than 4 GiB. This patch address the issue by simply promoting the terms to 64 bit, and let compilers decide how to do the multiplication efficiently. Signed-off-by: Ma Haijun <mahaijuns@gmail.com>

Fix ext2/ext4 filesystem accesses beyond 2TiB 2013-07-15T21:06:13+00:00 Frederic Leroy fredo@starox.org 2013-06-26T16:11:25+00:00 04735e9c5578dd4f3584be5454b9779e8e5c2af9 With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>

fs/ext4: Support device block sizes != 512 bytes 2013-05-10T12:16:33+00:00 Egbert Eich eich@suse.com 2013-05-01T01:13:19+00:00 50ce4c07df1c98aabf4630b35152ed95a87242f7 The 512 byte block size was hard coded in the ext4 file systems. Large harddisks today support bigger block sizes typically 4096 bytes. This patch removes this limitation. Signed-off-by: Egbert Eich <eich@suse.com>
