* block/partitions/mac.c: obey the state->limit constraintMing Lei2013-02-271-0/+4
| | | | | | | | | | | | | | It isn't necessary to read the information of partitions whose number is equal and more than state->limit since only maximum state->limit partitions will be added inside rescan_partitions(). That is also what other kind of partitions are doing.

UEFI 2.3.1D will include a change to the spec language mandating that a GPT header must be greater than *or equal to* the size of the defined structure. While verifying that this would work on Linux, I discovered that we're not actually checking the minimum bound at all. The result of this is that when we verify the checksum, it's possible that on a malformed header (with header_size of 0), we won't actually verify any data.

* block/partition/msdos: detect AIX formatted disks even without 55aaPhilippe De Muyter2013-02-271-3/+8
| | | | | | | | | | | | | | | | | | AIX formatted disks do not always have the MSDOS 55aa signature. This happens e.g. for unbootable AIX disks. Up to now, such disks were not recognized as AIX disks, because of the missing 55aa. Fix that by inverting the two tests. Let's first check for the AIX magic strings, and only if that fails check for the MSDOS magic word.

* ipmi: add new kernel options to prevent automatic ipmi initCorey Minyard2013-02-271-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The configuration change building ipmi_si into the kernel precludes the use of a custom driver that can utilize more than one KCS interface, multiple IPMBs, and more than one BMC. This capability is important for fault-tolerant systems. Even if the kernel option ipmi_si.trydefaults=0 is specified, ipmi_si discovers and claims one of the KCS interfaces on a Stratus server. The inability to now prevent the kernel from managing this device is a regression from previous kernels. The regression breaks a capability fault-tolerant vendors have relied upon. To support both ACPI opregion access and the need to avoid activation of ipmi_si on some platforms, we've added two new kernel options, ipmi_si.tryacpi and ipmi_si.trydmi be added to prevent ipmi_si from initializing when these options are set to 0 on the kernel command line. With these options at the default value of 1, ipmi_si init proceeds according to the kernel default.

* idr: explain WARN_ON_ONCE() on negative IDs out-of-range IDTejun Heo2013-02-271-0/+10
| | | | | | | | | | | | | | | | | Until recently, when an negative ID is specified, idr functions used to ignore the sign bit and proceeded with the operation with the rest of bits, which is bizarre and error-prone. The behavior recently got changed so that negative IDs are treated as invalid but we're triggering WARN_ON_ONCE() on negative IDs just in case somebody was depending on the sign bit being ignored, so that those can be detected and fixed easily. We only need this for a while. Explain why WARN_ON_ONCE()s are there and that they can be removed later.

* idr: implement lookup hintTejun Heo2013-02-272-23/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | While idr lookup isn't a particularly heavy operation, it still is too substantial to use in hot paths without worrying about the performance implications. With recent changes, each idr_layer covers 256 slots which should be enough to cover most use cases with single idr_layer making lookup hint very attractive. This patch adds idr->hint which points to the idr_layer which allocated an ID most recently and the fast path lookup becomes if (look up target's prefix matches that of the hinted layer) return hint->ary[ID's offset in the leaf layer]; which can be inlined. idr->hint is set to the leaf node on idr_fill_slot() and cleared from free_layer().

* idr: make idr_layer largerTejun Heo2013-02-271-8/+7
| | | | | | | | | | | | | | | | | | With recent preloading changes, idr no longer keeps full layer cache per each idr instance (used to be ~6.5k per idr on 64bit) and the previous patch removed restriction on the bitmap size. Both now allow us to have larger layers. Increase IDR_BITS to 8 regardless of BITS_PER_LONG. Each layer is slightly larger than 2k on 64bit and 1k on 32bit and carries 256 entries. The size isn't too large, especially compared to what we used to waste on per-idr caches, and 256 entries should be able to serve most use cases with single layer. The max tree depth is 4 which is much better than the previous 6 on 64bit and 7 on 32bit.

* idr: remove length restriction from idr_layer->bitmapTejun Heo2013-02-272-28/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, idr->bitmap is declared as an unsigned long which restricts the number of bits an idr_layer can contain. All bitops can handle arbitrary positive integer bit number and there's no reason for this restriction. Declare idr_layer->bitmap using DECLARE_BITMAP() instead of a single unsigned long. * idr_layer->bitmap is now an array. '&' dropped from params to bitops. * Replaced "== IDR_FULL" tests with bitmap_full() and removed IDR_FULL. * Replaced find_next_bit() on ~bitmap with find_next_zero_bit(). * Replaced "bitmap = 0" with bitmap_clear().

* idr: remove MAX_IDR_MASK and move left MAX_IDR_* into idr.cTejun Heo2013-02-276-22/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MAX_IDR_MASK is another weirdness in the idr interface. As idr covers whole positive integer range, it's defined as 0x7fffffff or INT_MAX. Its usage in idr_find(), idr_replace() and idr_remove() is bizarre. They basically mask off the sign bit and operate on the rest, so if the caller, by accident, passes in a negative number, the sign bit will be masked off and the remaining part will be used as if that was the input, which is worse than crashing. The constant is visible in idr.h and there are several users in the kernel. * drivers/i2c/i2c-core.c:i2c_add_numbered_adapter() Basically used to test if adap->nr is a negative number which isn't -1 and returns -EINVAL if so. idr_alloc() already has negative @start checking (w/ WARN_ON_ONCE), so this can go away. * drivers/infiniband/core/cm.c:cm_alloc_id() drivers/infiniband/hw/mlx4/cm.c:id_map_alloc() Used to wrap cyclic @start. Can be replaced with max(next, 0). Note that this type of cyclic allocation using idr is buggy. These are prone to spurious -ENOSPC failure after the first wraparound. * fs/super.c:get_anon_bdev() The ID allocated from ida is masked off before being tested whether it's inside valid range. ida allocated ID can never be a negative number and the masking is unnecessary. Update idr_*() functions to fail with -EINVAL when negative @id is specified and update other MAX_IDR_MASK users as described above. This leaves MAX_IDR_MASK without any user, remove it and relocate other MAX_IDR_* constants to lib/idr.c.

* idr: fix top layer handlingTejun Heo2013-02-271-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most functions in idr fail to deal with the high bits when the idr tree grows to the maximum height. * idr_get_empty_slot() stops growing idr tree once the depth reaches MAX_IDR_LEVEL - 1, which is one depth shallower than necessary to cover the whole range. The function doesn't even notice that it didn't grow the tree enough and ends up allocating the wrong ID given sufficiently high @starting_id. For example, on 64 bit, if the starting id is 0x7fffff01, idr_get_empty_slot() will grow the tree 5 layer deep, which only covers the 30 bits and then proceed to allocate as if the bit 30 wasn't specified. It ends up allocating 0x3fffff01 without the bit 30 but still returns 0x7fffff01. * __idr_remove_all() will not remove anything if the tree is fully grown. * idr_find() can't find anything if the tree is fully grown. * idr_for_each() and idr_get_next() can't iterate anything if the tree is fully grown. Fix it by introducing idr_max() which returns the maximum possible ID given the depth of tree and replacing the id limit checks in all affected places. As the idr_layer pointer array pa[] needs to be 1 larger than the maximum depth, enlarge pa[] arrays by one. While this plugs the discovered issues, the whole code base is horrible and in desparate need of rewrite.

| | | | | | | | | | | | | | | | | | | | | | Convert to the much saner new idr interface. The new interface doesn't directly translate to the way idr_pre_get() was used around ipc_addid() as preloading disables preemption. From my cursory reading, it seems like we should be able to do all allocation from ipc_addid(), so I moved it there. Can you please check whether this would be okay? If this is wrong and ipc_addid() should be allowed to be called from non-sleepable context, I'd suggest allocating id itself in the outer functions and later install the pointer using idr_replace().
