* compat_ioctl: move common block ioctls to compat_blkdev_ioctlArnd Bergmann2007-10-10
| | | | | | | | | | | | Make compat_blkdev_ioctl and blkdev_ioctl reflect the respective native versions. This is somewhat more efficient and makes it easier to keep the two in sync. Also get rid of the bogus handling for broken_blkgetsize and the duplicate entry for BLKRASET. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* Sysace: Don't enable IRQ until after interrupt handler is registeredGrant Likely2007-10-10
| | | | | | | | | The previous patch to move the interrupt handler registration moved it below enabling interrupts which could be a problem if the device is on a shared interrupt line.

* drivers/block/umem: use dev_printk()Jeff Garzik2007-10-10
| | | | | | | | | | dev_printk() gives us a consistent prefix (driver name + PCI bus id), which allows us to eliminate the hand-rolled one. Also allows us to eliminate card->card_number, which was used solely in printk() calls. Signed-off-by: Jeff Garzik <jeff@garzik.org>

* Drop 'size' argument from bio_endio and bi_end_ioNeilBrown2007-10-10
| | | | | | | | | | | | | As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void.

* Don't decrement bi_size in bio_endioNeilBrown2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | The only caller of bio_endio that does not pass the full bi_size is end_that_request_first. Also, no ->bi_end_io method is really interested in bi_size being decremented. So move the decrement and related code into ll_rw_blk and merge it with order_bio_endio to form req_bio_endio which does endio functionality specific to request completion. As some ->bi_end_io methods do check bi_size of 0, we set it thus for now, but that will go in the next patch.

| | | | | | | | | | | | | | | | | umem.c: advances bi_idx and bi_sector to track where it is up to. But it is only ever doing this on one bio, so the updated fields can easily be kept elsewhere (current_*). updates bi_size, but never uses the updated values, so this isn't needed. reuses bi_phys_segments to count how many iovecs have been completely. As the completion happens sequentiually, we can store this information outside the bio too.

* Merge blk_recount_segments into blk_recalc_rq_segmentsNeilBrown2007-10-10
| | | | | | | | | | | | | | | | | | | blk_recalc_rq_segments calls blk_recount_segments on each bio, then does some extra calculations to handle segments that overlap two bios. If we merge the code from blk_recount_segments into blk_recalc_rq_segments, we can process the whole request one bio_vec at a time, and not need the messy cross-bio calculations. Then blk_recount_segments can be implemented by calling blk_recalc_rq_segments, passing it a simple on-stack request which stores just the bio.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the ICMPv6 Target address is multicast, Linux processes the redirect instead of dropping it. The problem is in this code in ndisc_redirect_rcv(): if (ipv6_addr_equal(dest, target)) { on_link = 1; } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) { ND_PRINTK2(KERN_WARNING "ICMPv6 Redirect: target address is not link-local.\n"); return; } This second check will succeed if the Target address is, for example, FF02::1 because it has link-local scope. Instead, it should be checking if it's a unicast link-local address, as stated in RFC 2461/4861 Section 8.1: - The ICMP Target Address is either a link-local address (when redirected to a router) or the same as the ICMP Destination Address (when redirected to the on-link destination). I know this doesn't explicitly say unicast link-local address, but it's implied. This bug is preventing Linux kernels from achieving IPv6 Logo Phase II certification because of a recent error that was found in the TAHI test suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the multicast address in the Destination field instead of Target field, so we were passing the test. This won't be the case anymore. The patch below fixes this problem, and also fixes ndisc_send_redirect() to not send an invalid redirect with a multicast address in the Target field. I re-ran the TAHI Neighbor Discovery section to make sure Linux passes all 245 tests now.

| * [TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKedIlpo Järvinen2007-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When only GSO skb was partially ACKed, no hints are reset, therefore fastpath_cnt_hint must be tweaked too or else it can corrupt fackets_out. The corruption to occur, one must have non-trivial ACK/SACK sequence, so this bug is not very often that harmful. There's a fackets_out state reset in TCP because fackets_out is known to be inaccurate and that fixes the issue eventually anyway. In case there was also at least one skb that got fully ACKed, the fastpath_skb_hint is set to NULL which causes a recount for fastpath_cnt_hint (the old value won't be accessed anymore), thus it can safely be decremented without additional checking.

* | mm: set_page_dirty_balance() vs ->page_mkwrite()Peter Zijlstra2007-10-08
|/ | | | | | | | | | | | | | All the current page_mkwrite() implementations also set the page dirty. Which results in the set_page_dirty_balance() call to _not_ call balance, because the page is already found dirty. This allows us to dirty a _lot_ of pages without ever hitting balance_dirty_pages(). Not good (tm). Force a balance call if ->page_mkwrite() was successful. Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
