  "message": "omfs: fix sign confusion for bitmap loop counter\n\nThe count variable is used to iterate down to (below) zero from the size\nof the bitmap and handle the one-filling the remainder of the last\npartial bitmap block.  The loop conditional expects count to be signed\nin order to detect when the final block is processed, after which count\ngoes negative.\n\nUnfortunately, a recent change made this unsigned along with some other\nrelated fields.  The result of is this is that during mount,\nomfs_get_imap will overrun the bitmap array and corrupt memory unless\nnumber of blocks happens to be a multiple of 8 * blocksize.\n\nFix by changing count back to signed: it is guaranteed to fit in an s32\nwithout overflow due to an enforced limit on the number of blocks in the\nfilesystem.\n\nSigned-off-by: Bob Copeland \u003cme@bobcopeland.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
