2008-02-05drivers/pcmcia: add missing pci_dev_getJulia Lawall
pci_get_slot does a pci_dev_get, so pci_dev_put needs to be called in an error case. An extract of the semantic match used to find the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type find1.T,T1,T2; identifier find1.E; statement find1.S; expression x1,x2,x3; expression find1.test; int ret != 0; @@ T E; ...

2008-02-05drivers/pcmcia: Add missing iounmapJulia Lawall
of_iomap calls ioremap, and so should be matched with an iounmap. At the two error returns, the result of calling of_iomap is only stored in a local variable, so these error paths need to call iounmap. Furthermore, this function ultimately stores the result of of_iomap in an array that is local to the file. These values should be iounmapped at some point. I have added a corresponding call to iounmap at the end of the function m8xx_remove. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * E = of_iomap(...); if (E == NULL) S ... when != iounmap(...,(T1)E,...) when != if (E != NULL) { ... iounmap(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != iounmap(...,(T2)E,...) when != if (E != NULL) { ... iounmap(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Vitaly Bordug <vitb@kernel.crashing.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Olof Johansson <olof@lixom.net> Cc: Dominik Brodowski <linux@dominikbrodowski.net> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Kumar Gala <galak@kernel.crashing.org> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-02-05pcmcia: convert some internal-only ioaddr_t to unsigned intOlof Johansson
Convert the io_req_t members to unsigned int, to allow use on machines with more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc). There was only a couple of places in drivers where a change was needed. I left printk formats alone (there are lots of %04x-style formats in there), mostly to not change the format on the platforms that only have 16-bit io addresses, but also because the padding doesn't really add all that much value most of the time. I found only one sprintf of an address, and upsized the string accordingly (I doubt anyone will have anywhere near INT_MAX as irq value, but at least there's room for it now).

2008-02-05[S390] dcss: Initialize workqueue before using it.Heiko Carstens
In case a dcss segment cannot be loaded blk_cleanup_queue will be called before blk_queue_make_request, leaving the struct work unplug_work of the request queue uninitialized before it is used. That leads also to the lockdep message below. To avoid that call blk_queue_make_request right after the request_queue has been allocated. This makes sure that the struct work is always initialized before it is used.

When an alias device is set offline while it is in use this may result in a panic in the cleanup part of the dasd_block_tasklet. The problem here is that there may exist some ccw requests that were originally created for the alias device and transferred to the base device when the alias was set offline. When these request are cleaned up later, the discipline pointer in the alias device may not be valid anymore. To fix this use the base device discipline to find the cleanup function.

More critically, the VM DIAG call will always be considered to have provided data after such an incident, even if it was not successful at all. The solution is to always initialize the control unit data before doing a sense id call. Check the condition code before considering the control unit data.

2008-02-05tun: impossible to deassert IFF_ONE_QUEUE or IFF_NO_PINathaniel Filardo
From: "Nathaniel Filardo" <nwfilardo@gmail.com> Taken from http://bugzilla.kernel.org/show_bug.cgi?id=9806 The TUN/TAP driver only permits one-way transitions of IFF_NO_PI or IFF_ONE_QUEUE during the lifetime of a tap/tun interface. Note that tun_set_iff contains 541 if (ifr->ifr_flags & IFF_NO_PI) 542 tun->flags |= TUN_NO_PI; 543 544 if (ifr->ifr_flags & IFF_ONE_QUEUE) 545 tun->flags |= TUN_ONE_QUEUE; This is easily fixed by adding else branches which clear these bits. Steps to reproduce: This is easily reproduced by setting an interface persistant using tunctl then attempting to open it as IFF_TAP or IFF_TUN, without asserting the IFF_NO_PI flag. The ioctl() will succeed and the ifr.flags word is not modified, but the interface remains in IFF_NO_PI mode (as it was set by tunctl).

2008-02-05agp: remove unnecessary pci_dev_putJulia Lawall
pci_get_class implicitly does a pci_dev_put on its second argument, so pci_dev_put is only needed if there is a break out of the loop. The semantic match detecting this problem is as follows: // <smpl> @@ expression dev; expression E; @@ * pci_dev_put(dev) ... when != dev = E ( * pci_get_device(...,dev) | * pci_get_device_reverse(...,dev) | * pci_get_subsys(...,dev) | * pci_get_class(...,dev) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Dave Jones <davej@codemonkey.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Dave Airlie <airlied@linux.ie>
2008-02-05agp: remove uid comparison as security checkserue@us.ibm.com
In the face of containers and user namespaces, a uid==0 check for security is not safe. Switch to a capability check. I'm not sure I picked the right capability, but this being AGP CAP_SYS_RAWIO seemed to make sense. Signed-off-by: Serge Hallyn <serue@us.ibm.com> Signed-off-by: Dave Airlie <airlied@linux.ie>

2008-02-05agp/intel: Add chipset flushing support for i8xx chipsets.Dave Airlie
This is a bit of a large hammer but it makes sure the chipset is flushed by writing out 1k of data to an uncached page. We may be able to get better information in the future on how to this better. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-02-05intel-agp: add chipset flushing supportDave Airlie
This adds support for flushing the chipsets on the 915, 945, 965 and G33 families of Intel chips. The BIOS doesn't seem to always allocate the BAR on the 965 chipsets so I have to use pci resource code to create a resource It adds an export for pcibios_align_resource.
2008-02-05agp: add chipset flushing support to AGP interfaceDave Airlie
This bumps the AGP interface to 0.103. Certain Intel chipsets contains a global write buffer, and this can require flushing from the drm or X.org to make sure all data has hit RAM before initiating a GPU transfer, due to a lack of coherency with the integrated graphics device and this buffer. This just adds generic support to the AGP interfaces, a follow-on patch will add support to the Intel driver to use this interface. Signed-off-by: Dave Airlie <airlied@redhat.com>

If the allocation of the MTT or the mailbox failed, mthca_fmr_alloc() would return 0 (success) no matter what. This leads to crashes a little down the road, when we try to dereference eg mr->mtt, which was really ERR_PTR(-Ewhatever).

2008-02-04IB/ib_mthca: Pre-link receive WQEs in Tavor modeEli Cohen
We have recently discovered that Tavor mode requires each WQE in a posted list of receive WQEs to have a valid NDA field at all times. This requirement holds true for regular QPs as well as for SRQs. This patch prelinks the receive queue in a regular QP and keeps the free list in SRQ always properly linked.

2008-02-04IB/srp: Retry stale connectionsDavid Dillow
When a host just goes away (crash, power loss, etc.) without tearing down its IB connections, it can get stale connection errors when it tries to reconnect to targets upon rebooting. Retrying the connection a few times will prevent sysadmins from playing the "which disk(s) went missing?" game. This would have made things slightly quicker when tracking down some of the recent bugs, but it also helps quite a bit when you've got a large number of targets hanging off a wedged server.
