nvram: fix memory leak

2017-08-22T12:31:32+00:00

Fix memory leak on nvram_open() and nvram_open_rdonly().

For nvram_open(), the 'fd' should be closed on error, and
mmap_area should be unmap when nvram magic can not be found.

For nvram_open_rdonly(), the 'file' variable should free before
return. Once nvram_find_mtd() return successfully, it will allocate
memory to save mtd device string.

Revert "Revert "nvram: increase NVRAM size to 64 KiB""

2015-07-07T22:06:04+00:00

This reverts commit r45579.

With the latest change r46251 ("nvram: fix "Segmentation fault" caused
by setting memory out of buffer") nvram utility shouldn't crash anymore.

It was tested on 3 brcm47xx devices:
1) Unknown with 0x10000 NVRAM size (0x8000 offset)
2) Linksys E1000 V2.1 with 0x10000 (0x8000 offset)
3) Linksys WRT300N V1 with 0x10000 (0x8000 offset)

And 3 bcm53xx devices:
1) Buffalo WZR-600DHP2 with 0x160000 NVRAM size
2) Buffalo WZR-1750DHP with 0x10000 NVRAM size
3) Netgear R6250 V1 with 0x180000 NVRAM size
(all using 0 offset)

This is an important change as it allows reading whole NVRAM. This may
critical when reading some basic configuration (e.g. switch ports).

nvram: fix "Segmentation fault" caused by setting memory out of buffer

2015-07-07T21:21:49+00:00

Some MTD partitions with NVRAM have content starting in the middle. In
such case offset is set and nvram_header returns pointer to the middle.
It means we have to respect offset when calculating remaining space.

By the way use real MTD partition size (nvram_part_size variable) as we
may want to bump NVRAM_SPACE in the (very near) future.

This reverts commit ff84c27a281bc19df19bc62ee8688cca5586f6e3.
This tool has really broken size handling (many values hardcoded), it
crashes right now in case of NVRAM not filling whole MTD partition.
