2018-12-02mtd: improve calculating partition boundaries when checking for alignmentRafał Miłecki1-2/+11
When checking for alignment mtd should check absolute offsets. It's important for subpartitions as it doesn't make sense to check their relative addresses. Signed-off-by: Rafał Miłecki <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
2018-12-02mtd: keep original flags for every struct mtd_infoRafał Miłecki3-1/+5
When allocating a new partition mtd subsystem runs internal tests in the allocate_partition(). They may result in modifying specified flags (e.g. dropping some /features/ like write access). Those constraints don't have to be necessary true for subpartitions. It may happen parent partition isn't block aligned (effectively disabling write access) while subpartition may fit blocks nicely. In such case all checks should be run again (starting with original flags value). Signed-off-by: Rafał Miłecki <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
2018-12-02mtd: fix Coverity integer handling issueMiquel Raynal1-3/+3
A Coverity robot reported an integer handling issue (OVERFLOW_BEFORE_WIDEN) in the potentially overflowing expression: (mtd_div_by_ws(mtd->size, mtd) - mtd_div_by_ws(offs, mtd)) * mtd_oobavail(mtd, ops) While such overflow will certainly never happen due to the numbers handled, it is cleaner to fix this operation anyway. The problem is that all the maths include 32-bit quantities, while the result is stored in an explicit 64-bit value. As maxooblen will just be compared with a size_t, let's change the type of the variable to a size_t. This will not fix anything but will clarify a bit the situation. Then, do an explicit cast to fix Coverity warning. Signed-off-by: Miquel Raynal <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
2018-12-02mtd: fix mtd_oobavail() incoherent returned valueMiquel Raynal1-1/+1
mtd_oobavail() returns either mtd->oovabail or mtd->oobsize. Both values are unsigned 32-bit entities, so there is no reason to pretend returning a signed one. Signed-off-by: Miquel Raynal <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>

2018-12-02jffs2: Fix use of uninitialized delayed_work, lockdep breakageDaniel Santos1-1/+2
jffs2_sync_fs makes the assumption that if CONFIG_JFFS2_FS_WRITEBUFFER is defined then a write buffer is available and has been initialized. However, this does is not the case when the mtd device has no out-of-band buffer: int jffs2_nand_flash_setup(struct jffs2_sb_info *c) { if (!c->mtd->oobsize) return 0; ... The resulting call to cancel_delayed_work_sync passing a uninitialized (but zeroed) delayed_work struct forces lockdep to become disabled. [ 90.050639] overlayfs: upper fs does not support tmpfile.

Controlling some MSB address lines using GPIOs is just a small deviation from the generic physmap logic, and merging those two drivers allows us to share most of the probe logic, which is a good thing. Also, the gpio-addr-flash driver is unused since the removal of the blackfin arch in v4.17, so we can safely remove the old driver without risking breaking existing boards.

2018-11-03bfs: add sanity check at bfs_fill_super()Tetsuo Handa1-3/+6
syzbot is reporting too large memory allocation at bfs_fill_super() [1]. Since file system image is corrupted such that bfs_sb->s_start == 0, bfs_fill_super() is trying to allocate 8MB of continuous memory. Fix this by adding a sanity check on bfs_sb->s_start, __GFP_NOWARN and printf().
