Indeed, currently we just recover all buds, which is\nincorrect because only the last buds can have corruptions in case of a power\ncut. So it is inconsistent with the rest of the recovery strategy which tries\nhard to distinguish between corruptions cause by power cuts and other types of\ncorruptions.\n\nThis patch also adds one quirk - a bit older UBIFS was could have corruption in\nthe next to last bud because of the way it switched buds: when bud A is full,\nit first searched for the next bud B, the wrote a reference node to the log\nabout B, and then synchronized the write-buffer of A. So we could end up with\nbuds A and B, where B is the last, but A had corruption. The UBIFS behavior\nwas fixed, though, so currently it always first synchronizes A\u0027s write-buffer\nand only after this adds B to the log. However, to be make sure that we handle\nunclean (after a power cut) UBIFS images belonging to older UBIFS - we need to\nadd a quirk and keep it for some time: we need to check for the situation\ndescribed above.\n\nThankfully, it is easy to check for that situation. When UBIFS adds B to the\nlog, it always first unmaps B, then maps it, and then syncs A\u0027s write-buffer.\nThus, in that situation we can check that B is empty, in which case it is OK to\nhave corruption in A. To check that B is empty it is enough to just read the\nfirst few bytes of the bud and compare them with 0xFFs. This quirk may be\nremoved in a couple of years.\n\nSigned-off-by: Artem Bityutskiy \u003cArtem.Bityutskiy@nokia.com\u003e\n" }, { "commit": "cb14a18465686ea6add51b1008865b8174c28bd7", "tree": "9e1b7aa466e83c77628fa74af00049893db84c40", "parents": [ "c49139d8096dc1c392455dbc3f158b46038fc9d4" ], "author": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Sun May 15 14:51:54 2011 +0300" }, "committer": { "name": "Artem Bityutskiy", "email": "Artem.Bityutskiy@nokia.com", "time": "Mon May 16 10:31:41 2011 +0300" }, "message": "UBIFS: synchronize write-buffer before switching to the next bud\n\nCurrently when UBIFS fills up the current bud (which is the last in the journal\nhead) and switches to the next bud, it first writes the log reference node for\nthe next bud and only after this synchronizes the write-buffer of the previous\nbud.
