2014-07-19UBI: init_volumes: Ignore volumes with no LEBsRichard Weinberger1-1/+1
UBI assumes that ubi_attach_info will only contain ubi_ainf_volume structures for volumes with at least one LEB. In scanning mode this is true because UBI can nicely create a ubi_ainf_volume on demand while creating the EBA table. For fastmap this is not true, the fastmap on-flash structure has a list of all volumes, the ubi_ainf_volume structures are created from this list. So it can happen that an empty volume ends up in init_volumes(). We can easely deal with that by looking into ->leb_count too.

2012-09-04UBI: fix a horrible memory deallocation bugArtem Bityutskiy1-2/+2
UBI was mistakingly using 'kfree()' instead of 'kmem_cache_free()' when freeing "attach eraseblock" structures in vtbl.c. Thankfully, this happened only when we were doing auto-format, so many systems were unaffected. However, there are still many users affected. It is strange, but the system did not crash and nothing bad happened when the SLUB memory allocator was used. However, in case of SLOB we observed an crash right away. This problem was introduced in 2.6.39 by commit "6c1e875 UBI: add slab cache for ubi_scan_leb objects" A note for stable trees: Because variable were renamed, this won't cleanly apply to older kernels. Changing names like this should help: 1. ai -> si 2. aeb_slab_cache -> seb_slab_cache 3. new_aeb -> new_seb Reported-by: Richard Genoud <richard.genoud@gmail.com> Tested-by: Richard Genoud <richard.genoud@gmail.com> Tested-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Cc: stable@vger.kernel.org [v2.6.39+] Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

This patch adds a possibility to dynamically switch UBI self-checks on and off, instead of toggling them compile-time from the configuration menu.

2010-10-19UBI: preserve corrupted PEBsArtem Bityutskiy1-2/+6
Currently UBI erases all corrupted eraseblocks, irrespectively of the nature of corruption: corruption due to power cuts and non-power cut corruption. The former case is OK, but the latter is not, because UBI may destroy potentially important data. With this patch, during scanning, when UBI hits a PEB with corrupted VID header, it checks whether this PEB contains only 0xFF data. If yes, it is safe to erase this PEB and it is put to the 'erase' list. If not, this may be important data and it is better to avoid erasing this PEB. Instead, UBI puts it to the corr list and moves out of the pool of available PEB. IOW, UBI preserves this PEB. Such corrupted PEB lessen the amount of available PEBs. So the more of them we accumulate, the less PEBs are available. The maximum amount of non-power cut corrupted PEBs is 8. This patch is a response to UBIFS problem where reporter (Matthew L. Creech <mlcreech@gmail.com>) observes that UBIFS index points to an unmapped LEB. The theory is that corresponding PEB somehow got corrupted and UBI wiped it. This patch (actually a series of patches) tries to make sure such PEBs are preserved - this would make it is easier to analyze the corruption. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-10-19UBI: do not put eraseblocks to the corrupted list unnecessarilyArtem Bityutskiy1-1/+1
Currently UBI maintains 2 lists of PEBs during scanning: 1. 'erase' list - PEBs which have no corruptions but should be erased 2. 'corr' list - PEBs which have some corruptions and should be erased But we do not really need 2 lists for PEBs which should be erased after scanning is done - this is redundant. So this patch makes sure all PEBs which are corrupted are moved to the head of the 'erase' list. We add them to the head to make sure they are erased first and we get rid of corruption ASAP. However, we do not remove the 'corr' list and realted functions, because the plan is to use this list for other purposes. Namely, we plan to put eraseblocks with corruption which does not look like it was caused by unclean power cut. Then we'll preserve thes PEBs in order to avoid killing potentially valuable user data. This patch also amends PEBs accounting, because it was closely tight to the 'erase'/'corr' lists separation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Before UBI got into mainline, there was a slight flash format change - we did not have sequence number support, then added it. We have carried full support of those ancient images till this moment. Now the support is removed, well, not fully removed. Now UBI will support only _clean_ old images, which were cleanly detached last time (just before kernel upgrade). This is most likely the case. But we will not support unclean ancient images. Surprisingly, this allows us to remove a big chunk of legacy code.
