* readline: Fix history prev when history is emptySascha Hauer2014-09-011-1/+5
| | | | | | | | | | | | | | | | We cannot use list_entry() on an empty list. Without history we have to return an empty line. This fixes a crash when the cursor up button is pressed and no command has been entered previously. Broken since: commit ada160a34a1ec8421d5bb7b9dd746294668a5130 Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue Jul 29 11:54:26 2014 +0200 readline: reimplement history functions Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Teresa Gamez <t.gamez@phytec.de>

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reimplements the history functions in readline. - Use regular lists instead of homegrown list implementation - Allocate history strings dynamically instead of copying strings to fixed buffers without checking the size - saves us an initcall - slightly smaller - no longer add duplicates to the history - when moving past the last history entry print an empty line Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | read_file: introduce read_file_2Sascha Hauer2014-08-071-14/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read_file has some limitations: - It is not possible to check the error code since read_file returns NULL for failure - It is not possible to limit the buffer size to sensible limits. This patch introduces read_file_2 which doesn't have these limitations. read_file becomes a wrapper around read_file_2. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* lz4: fix another possible overrunHolger Schurig2014-07-021-1/+3

There is one other possible overrun in the lz4 code as implemented by Linux at this point in time (which differs from the upstream lz4 codebase, but will get synced at in a future kernel release.) As pointed out by Don, we also need to check the overflow in the data itself. While we are at it, replace the odd error return value with just a "simple" -1 value as the return value is never used for anything other than a basic "did this work or not" check.

| * mtd: Update internal API to support 64-bit device sizeDmitry Lavnikevich2014-03-121-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MTD internal API presently uses 32-bit values to represent device size. This patch updates them to 64-bits but leaves the external API unchanged. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats; - division and modulus of 64-bit values (mtd_div_by_wb, mtd_div_by_eb may be used in some of such cases).
