* packages: nvram: fix memory leak in _nvram_freeZhai Zhaoxuan2017-11-151-0/+4
| | | | | | | The value of nvram_tuple_t is allocated in _nvram_realloc, but it is not freed in _nvram_free. Signed-off-by: Zhai Zhaoxuan <zhaizhaoxuan@xiaomi.com>
* nvram: add help message for nvram magic not foundBangLang Huang2017-08-221-0/+1
| | | | | | | The program would failed if nvram magic not found in specific partition. Signed-off-by: BangLang Huang <banglang.huang@foxmail.com>
* nvram: improve argument check when program startBangLang Huang2017-08-221-8/+9
| | | | | | | print help message when argument count is less than 2. Signed-off-by: BangLang Huang <banglang.huang@foxmail.com>
* nvram: add usage() functionBangLang Huang2017-08-221-10/+13
| | | | | | | Merge the help message into a single function, so that we can use it somewhere else. Signed-off-by: BangLang Huang <banglang.huang@foxmail.com>
* nvram: fix memory leakBangLang Huang2017-08-222-3/+10
| | | | | | | | | | | | | 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. Signed-off-by: BangLang Huang <banglang.huang@foxmail.com>
* nvram: get rid of NVRAM_SPACERafał Miłecki2015-07-082-3/+2
| | | | | | | | Now we support NVRAM whatever its size is. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 46262
* nvram: fix displayed info about NVRAM sizeRafał Miłecki2015-07-081-2/+2
| | | | | | | | Use actual partition size and content offset to calculate it. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 46260
* Revert "Revert "nvram: increase NVRAM size to 64 KiB""Rafał Miłecki2015-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 46253
* nvram: fix "Segmentation fault" caused by setting memory out of bufferRafał Miłecki2015-07-071-2/+2
| | | | | | | | | | | | | 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.

* Revert "nvram: increase NVRAM size to 64 KiB"Rafał Miłecki2015-04-241-1/+1
| | | | | | | | | | | | | 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.

* nvram: fix regression in finding NVRAM beginningRafał Miłecki2015-04-242-1/+7
| | | | | | | | | The loop was giving up too early as it never expected NVRAM smaller than 0x10000. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 45578
* nvram: increase NVRAM size to 64 KiBRafał Miłecki2015-04-221-1/+1
| | | | | | | | | | | | | For years Broadcom devices use 64 KiB NVRAM partition size and some of them indeed have it filled in more than 50%. This change allows handling whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000. The same fix was applied to kernel in upstream commit 6ab7c29.

* nvram: drop check for WGT634U using /proc/diag/modelRafał Miłecki2015-04-221-11/+1
| | | | | | | | | We don't have broadcom-diag for months or years now and the correct solution is to simply don't have "nvram" partition on WGT634U anyway. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 45564
* nvram: use correct variable name for MTD partition sizeRafał Miłecki2015-04-221-13/+14
| | | | | | | | | | Sytax of /proc/mtd is following: dev: size erasesize name which means that sscanf "mtd%d: %08x" reads size, not erasesize. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 45563
