2018-09-20cmd: mtdparts: remove mandatory 'mtdparts=' prefixMiquel Raynal
All U-Boot users must define the mtdparts environment variable with: setenv mtdparts mtdparts=... While this may ease the partition declaration job to be passed to Linux, this is a pure software limitation and forcing this prefix is a complete non-sense. Let the user to declare manually the mtdparts variable without the prefix.

2018-07-24mtdparts: fixed buffer overflow bugKay Potthoff
In the case that there was no name defined for a partition the code assumes that name_len is 22 and therefore allocates exactly that space for a dummy name. But the function sprintf() first resolves "0x%08llx@0x%08llx" to a string that is longer than 22 bytes. This leads to a buffer overflow. The replacement function snprintf() limits the copied bytes to name_len and therefore avoids the buffer overflow. Signed-off-by: Kay Potthoff <Kay.Potthoff@microsys.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-08-26mtdparts: Fix final outstanding issue reported by CoverityTom Rini
As part of fixing the previously reported issues, it was missed that in the case of mtdparts_init() we need to make sure that tmp_ep is long enough to contain PARTITION_MAXLEN and a NULL termination. Then, to be sure the buffer is NULL terminated, zero the entire buffer rather than just ensuring the first character is NULL.

2017-08-20mtdparts: Fix various issues reported by CoverityTom Rini
Now that sandbox is building cmd/mtdparts.c Coverity has looked at the code and found a number of issues. In index_partitions() it is possible that part will be NULL, so re-work the checks and debug statements to take this into account. We have a number of string buffers that we print to in the exact size of, and use string functions on, so we need to ensure they are large enough to be NULL terminated. In device_parse() it is not possible for num_partitions to be 0 (we would have hit a different error first) so remove logically dead code. Finally, in parse_mtdparts() if we have an error we need to free the memory allocated to dev.

2017-04-07cmd: Add Kconfig option for CMD_MTDPARTS and related optionsMaxime Ripard
CMD_MTDPARTS is something the user might or might not want to select, and might depends on (or be selected by) other options too. This is even truer for the MTDIDS_DEFAULT and MTDPARTS_DEFAULT options that might change from one board to another, or from one user to the other, depending on what it expects and what storage devices are available. In order to ease that configuration, add those options to Kconfig.

2016-07-22cmd: mtdparts: support runtime generated mtdpartsLadislav Michl
Some CPUs contains boot ROM code capable reading first few blocks (where SPL resides) of NAND flash and executing it. It is wise to create separate partition here for SPL. As block size depends on NAND chip used, we could either use worst case (biggest) partition size or base its size on actual block size. This patch adds support for the latter option.

2016-07-22cmd: mtdparts: use defaults by defaultLadislav Michl
Boards which are defining default mtdparts often need them early in boot process (to load environment from UBI volume, for example). This is currently solved by adding mtdparts and mtdids variable definitions also to default environment. With this change, default partitions are used by default unless explicitely deleted or redefined. Signed-off-by: Ladislav Michl <ladis@linux-mips.org>

In case there is no mtdparts variable in relocated environment, NULL is assigned to p, which is later fed to strncpy. Also function parameter mtdparts is completely ignored, so use it in case mtdparts variable is not found in environment. This parameter is checked not to be NULL in caller.
