* edac: fix module initialization on several modules 2nd timeHitoshi Mitake2008-04-2911-40/+66
| | | | | | | | | | | | | | | | | | | | | I implemented opstate_init() as a inline function in linux/edac.h. added calling opstate_init() to: i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c I wrote a fixed patch of edac-fix-module-initialization-on-several-modules.patch, and tested building 2.6.25-rc7 with applying this. It was succeed. I think the patch is now correct.

* edac: remove unneeded functions and add static accessorAdrian Bunk2008-04-295-59/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Collection of patches, merged into one, from Adrian that do the following: 1) This patch makes the following needlessly global functions static: - edac_pci_get_log_pe() - edac_pci_get_log_npe() - edac_pci_get_panic_on_pe() - edac_pci_unregister_sysfs_instance_kobj() - edac_pci_main_kobj_setup() 2) Remove unneeded function edac_device_find() 3) Added #if 0 around function edac_pci_find() 4) make the needlessly global edac_pci_generic_check() static 5) Removed function edac_check_mc_devices() Doug Thompson modified Adrian's patches, to bettern represent the direction of EDAC, and make them one patch.

* edac: add e752x parameter for sysbus_parity selectionPeter Tyser2008-04-291-1/+39
| | | | | | | | | | | | | | | | | | | | | Add a module parameter "sysbus_parity" to allow forcing system bus parity error checking on or off. Also add support to automatically disable system bus parity errors for processors which do not support it. If the sysbus_parity parameter is specified, sysbus parity detection will be forced on or off. If it is not specified, the driver will attempt to look at the CPU identifier string and determine if the CPU supports system bus parity. A blacklist was used instead of a whitelist so that system bus parity would be enabled by default and to minimize the chances of breaking things for those people already using the driver which for some reason have a processor that does not have a valid CPU identifier string.

* random: make mixing interface byte-orientedMatt Mackall2008-04-291-18/+19
| | | | | | | | | | | | | | | | | | | | Switch add_entropy_words to a byte-oriented interface, eliminating numerous casts and byte/word size rounding issues. This also reduces the overall bit/byte/word confusion in this code. We now mix a byte at a time into the word-based pool. This takes four times as many iterations, but should be negligible compared to hashing overhead. This also increases our pool churn, which adds some depth against some theoretical failure modes. The function name is changed to emphasize pool mixing and deemphasize entropy (the samples mixed in may not contain any). extract is added to the core function to make it clear that it extracts from the pool.

* random: remove some prefetch logicMatt Mackall2008-04-291-6/+2
| | | | | | | | | | | | | | The urandom output pool (ie the fast path) fits in one cacheline, so this is pretty unnecessary. Further, the output path has already fetched the entire pool to hash it before calling in here. (This was the only user of prefetch_range in the kernel, and it passed in words rather than bytes!)

* random: make backtracking attacks harderMatt Mackall2008-04-291-19/+17
| | | | | | | | | | | | | | | | | At each extraction, we change (poolbits / 16) + 32 bits in the pool, or 96 bits in the case of the secondary pools. Thus, a brute-force backtracking attack on the pool state is less difficult than breaking the hash. In certain cases, this difficulty may be is reduced to 2^64 iterations. Instead, hash the entire pool in one go, then feedback the whole hash (160 bits) in one go. This will make backtracking at least as hard as inverting the hash.

The driver sets bdev->bd_invalidated to 1 to force the read of the partition table of the device, but this is done only on an open of the device. So we have to do a "touch /dev/nbdX" or something like that. It can't be done from the nbd-client or nbd driver because at this level we can't ask to read the partition table and to serve the request at the same time (-> deadlock) If someone has a better idea, I'm open to any suggestion. -------NOTE, RFC # fdisk -l /dev/nbd0 Disk /dev/nbd0: 82.3 GB, 82348277760 bytes 255 heads, 63 sectors/track, 10011 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/nbd0p1 * 1 9965 80043831 83 Linux /dev/nbd0p2 9966 10011 369495 5 Extended /dev/nbd0p5 9966 10011 369463+ 82 Linux swap / Solaris # ls -l /dev/nbd0* brw-rw---- 1 root disk 43, 0 2008-03-25 11:16 /dev/nbd0 brw-rw---- 1 root disk 43, 1 2008-03-25 11:16 /dev/nbd0p1 brw-rw---- 1 root disk 43, 2 2008-03-25 11:16 /dev/nbd0p2 brw-rw---- 1 root disk 43, 5 2008-03-25 11:16 /dev/nbd0p5 # mount /dev/nbd0p1 /mnt # ls /mnt bin dev initrd lost+found opt sbin sys var boot etc initrd.img media proc selinux tmp vmlinuz cdrom home lib mnt root srv usr # umount /mnt # nbd-client -d /dev/nbd0 # ls -l /dev/nbd0* brw-rw---- 1 root disk 43, 0 2008-03-25 11:16 /dev/nbd0 -------NOTE On "nbd-client -d", we can do an iocl(BLKRRPART) to update partition table: as the size of the device is 0, we don't have to serve the partition manager request (-> no deadlock). -------NOTE Signed-off-by: Paul Clements <paul.clements@steeleye.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* NBD: allow nbd to be used locallyLaurent Vivier2008-04-291-49/+95
| | | | | | | | | | | | | | | | | | | | This patch allows Network Block Device to be mounted locally (nbd-client to nbd-server over 127.0.0.1). It creates a kthread to avoid the deadlock described in NBD tools documentation. So, if nbd-client hangs waiting for pages, the kblockd thread can continue its work and free pages. I have tested the patch to verify that it avoids the hang that always occurs when writing to a localhost nbd connection. I have also tested to verify that no performance degradation results from the additional thread and queue. Patch originally from Laurent Vivier.

* proc: switch /proc/scsi/device_info to seq_file interfaceAlexey Dobriyan2008-04-291-33/+44
| | | | | | | | | | | | | | | Note 1: 0644 should be used, but root bypasses permissions, so writing to /proc/scsi/device_info still works. Note 2: looks like scsi_dev_info_list is unprotected Note 3: probably make proc whine about "unwriteable but with ->write hook" entries. Probably.
