| * [PATCH] splice: fix page stealing LRU handling.Jens Axboe2006-04-02
| | | | | | | | | | | | | | | | | | | | | | | | Originally from Nick Piggin, just adapted to the newer branch. You can't check PageLRU without holding zone->lru_lock. The page release code can get away with it only because the page refcount is 0 at that point. Also, you can't reliably remove pages from the LRU unless the refcount is 0. Ever.

| * [PATCH] splice: page stealing needs to wait_on_page_writeback()Jens Axboe2006-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to Andrew for the good explanation of why this is so. akpm writes: If a page is under writeback and we remove it from pagecache, it's still going to get written to disk. But the VFS no longer knows about that page, nor that this page is about to modify disk blocks. So there might be scenarios in which those blocks-which-are-about-to-be-written-to get reused for something else. When writeback completes, it'll scribble on those blocks. This won't happen in ext2/ext3-style filesystems in normal mode because the page has buffers and try_to_release_page() will fail. But ext2 in nobh mode doesn't attach buffers at all - it just sticks the page in a BIO, finds some new blocks, points the BIO at those blocks and lets it rip. While that write IO's in flight, someone could truncate the file. Truncate won't block on the writeout because the page isn't in pagecache any more. So truncate will the free the blocks from the file under the page's feet. Then something else can reallocate those blocks. Then write data to them. Now, the original write completes, corrupting the filesystem. Signed-off-by: Jens Axboe <axboe@suse.de>

| * [PATCH] splice: improve writeback and clean up page stealingJens Axboe2006-04-02
| | | | | | | | | | | | | | | | | | | | By cleaning up the writeback logic (killing write_one_page() and the manual set_page_dirty()), we can get rid of ->stolen inside the pipe_buffer and just keep it local in pipe_to_file(). This also adds dirty page balancing logic and O_SYNC handling. Signed-off-by: Jens Axboe <axboe@suse.de>
| * [PATCH] splice: fix shadow[] filling logicJens Axboe2006-04-02
| | | | | | | | | | | | | | | | | | Clear the entire range, and don't increment pidx or we keep filling the same position again and again. Thanks to KAMEZAWA Hiroyuki. Signed-off-by: Jens Axboe <axboe@suse.de>

| * | [CIFS] Incorrect signature sent on SMB ReadSteve French2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes Samba bug 3621 and kernel.org bug 6147 For servers which require SMB/CIFS packet signing, we were sending the wrong signature (all zeros) on SMB Read request. The new cifs routine to do signatures across an iovec was not complete - and SMB Read, unlike the new SMBWrite2, did not fall back to the older routine (ie use SendReceive vs. the more efficient SendReceive2 ie used the older cifs_sign_smb vs. the disabled cifs_sign_smb2) for calculating signatures. This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers of SendReceive2 can get SMB/CIFS packet signatures. Now that cifs_sign_smb2 is supported, we could start using it in the write path but this smaller fix does not include the change to use SMBWrite2 when signatures are required (which when enabled will make more Writes more efficient and alloc less memory). Currently Write2 is only used when signatures are not required at the moment but after more testing we will enable that as well). Thanks to James Slepicka and Sam Flory for initial investigation.
