2008-08-13x86: fix 2 section mismatch warnings - map_high()Marcin Slusarz

2008-08-13crypto: tcrypt - Fix AEAD chunk testingHerbert Xu
My changeset 4b22f0ddb6564210c9ded7ba25b2a1007733e784 crypto: tcrpyt - Remove unnecessary kmap/kunmap calls introduced a typo that broke AEAD chunk testing. In particular, axbuf should really be xbuf. There is also an issue with testing the last segment when encrypting. The additional part produced by AEAD wasn't tested. Similarly, on decryption the additional part of the AEAD input is mistaken for corruption. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-08-13crypto: talitos - Add handling for SEC 3.x treatment of link tableLee Nipper
Later SEC revision requires the link table (used for scatter/gather) to have an extra entry to account for the total length in descriptor [4], which contains cipher Input and ICV. This only applies to decrypt, not encrypt. Without this change, on 837x, a gather return/length error results when a decryption uses a link table to gather the fragments. This is observed by doing a ping with size of 1447 or larger with AES, or a ping with size 1455 or larger with 3des. So, add check for SEC compatible "fsl,3.0" for using extra link table entry.

2008-08-13x86: fix setup code crashes on my old 486 boxJoerg Roedel
yesterday I tried to reactivate my old 486 box and wanted to install a current Linux with latest kernel on it. But it turned out that the latest kernel does not boot because the machine crashes early in the setup code. After some debugging it turned out that the problem is the query_ist() function. If this interrupt with that function is called the machine simply locks up. It looks like a BIOS bug. Looking for a workaround for this problem I wrote the attached patch. It checks for the CPUID instruction and if it is not implemented it does not call the speedstep BIOS function. As far as I know speedstep should be available since some Pentium earliest. Alan Cox observed that it's available since the Pentium II, so cpuid levels 4 and 5 can be excluded altogether. H. Peter Anvin cleaned up the code some more: > Right in concept, but I dislike the implementation (duplication of the > CPU detect code we already have). Could you try this patch and see if > it works for you? which, with a small modification to fix a build error with it the resulting kernel boots on my machine.

2008-08-13net/rxrpc: Use an IS_ERR test rather than a NULL testJulien Brunel
In case of error, the function rxrpc_get_transport returns an ERR pointer, but never returns a NULL pointer. So after a call to this function, a NULL test should be replaced by an IS_ERR test. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @correct_null_test@ expression x,E; statement S1, S2; @@ x = rxrpc_get_transport(...) <... when != x = E if ( ( - x@p2 != NULL + !

2008-08-13pkt_sched: Add queue stopped test back to qdisc_run().David S. Miller
Based upon a bug report by Andrew Gallatin on netdev with subject "CPU utilization increased in 2.6.27rc" In commit 37437bb2e1ae8af470dfcd5b4ff454110894ccaf ("pkt_sched: Schedule qdiscs instead of netdev_queue.") the test of the queue being stopped was erroneously removed from qdisc_run().

2008-08-13UBIFS: reserve more space for indexArtem Bityutskiy
At the moment UBIFS reserves twice old index size space for the index. But this is not enough in some cases, because if the indexing node are very fragmented and there are many small gaps, while the dirty index has big znodes - in-the-gaps method would fail. Thus, reserve trise as more, in which case we are guaranteed that we can commit in any case. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-08-13UBIFS: align inode data to eightArtem Bityutskiy
UBIFS aligns node lengths to 8, so budgeting has to do the same. Well, direntry, inode, and page budgets are already aligned, but not inode data budget (e.g., data in special devices or symlinks).

2008-08-13UBIFS: optimize deletionsArtem Bityutskiy
Every time anything is deleted, UBIFS writes the deletion inode node twice - once in 'ubifs_jnl_update()' and the second time in 'ubifs_jnl_write_inode()'. However, the second write is not needed if no commit happened after 'ubifs_jnl_update()'. This patch checks that condition and avoids writing the deletion inode for the second time.

2008-08-13UBIFS: do not write orphans backArtem Bityutskiy
Orphan inodes are deleted inodes which will disappear after FS re-mount. There is not need to write orphan inodes back, because they are not needed on the flash media. So optimize orphans a little by not writing them back. Just mark them as clean, free the budget, and report success to VFS. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-08-13UBIFS: make ubifs_ro_mode() not inlineAdrian Hunter
We use ubifs_ro_mode() quite a lot, and not in fast-path, so there is no reason to blow the code up by having it inlined. Also, we usually want R/O mode change to be seen to other CPUs as soon as possible, so when we make this a function call, we will automatically have a memory barrier.

2008-08-13UBIFS: ensure UBIFS switches to read-only on errorAdrian Hunter
UBI transparently handles write errors by automatically copying and remapping the affected eraseblock. If UBI is unable to do that, for example its pool of eraseblocks reserved for bad block handling is empty, then the error is propagated to UBIFS. UBIFS must protect the media from falling into an inconsistent state by immediately switching to read-only mode. In the case of log updates, this was not being done. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
2008-08-13UBIFS: fix error return in failure modeAdrian Hunter

2008-08-13UBIFS: free budget in delete_inode as wellArtem Bityutskiy

2008-08-13UBIFS: fix budgeting calculationsArtem Bityutskiy
The 'ubifs_release_dirty_inode_budget()' was buggy and incorrectly freed the budget, which led to not freeing all dirty data budget. This patch fixes that.

Use KM_NOFS to prevent recursion back into the filesystem which can cause deadlocks. In the case of xfs_iread() we hold the lock on the inode cluster buffer while allocating memory for the trace buffers. If we recurse back into XFS to flush data that may require a transaction to allocate extents which needs log space. This can deadlock with the xfsaild thread which can't push the tail of the log because it is trying to get the inode cluster buffer lock.
