commit 12fed00d upstream. When we get oplock break notification we should set the appropriate value of OplockLevel field in oplock break acknowledge according to the oplock level held by the client in this time. As we only can have level II oplock or no oplock in the case of oplock break, we should be aware only about clientCanCacheRead field in cifsInodeInfo structure. Signed-off-by:

commit d11327ad upstream. NETDEV_NOTIFY_PEER is an explicit request by the driver to send a link notification while NETDEV_UP/NETDEV_CHANGEADDR generate link notifications as a sort of side effect. In the later cases the sysctl option is present because link notification events can have undesired effects e.g. if the link is flapping. I don't think this applies in the case of an explicit request from a driver. This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we could add a new sysctl for this case which defaults to on. This change causes Xen post-migration ARP notifications (which cause switches to relearn their MAC tables etc) to be sent by default. Signed-off-by:

commit 3ed78011 upstream. If the iowarrior devices in this case statement support more than 8 bytes per report, it is possible to write past the end of a kernel heap allocation. This will probably never be possible, but change the allocation to be more defensive anyway. Signed-off-by:

commit ba04c7c9 upstream. For some time is known that ASPM is causing troubles on r8169, i.e. make device randomly stop working without any errors in dmesg. Currently Tomi Leppikangas reports that system with r8169 device hangs with MCE errors when ASPM is enabled: https://bugzilla.redhat.com/show_bug.cgi?id=642861#c4 Lets disable ASPM for r8169 devices at all, to avoid problems with r8169 PCIe devices at least for some users.

commit 4def99bb upstream. When support for 82577/82578 was added[1] in 2.6.31, PHY wakeup was in- advertently enabled (even though it does not function properly) on ICH10 LOMs. This patch makes it so that the ICH10 LOMs use MAC wakeup instead as was done with the initial support for those devices (i.e. 82567LM-3, 82567LF-3 and 82567V-4).

commit 720dc34b upstream. This fixes a bug in the order of dccp_rcv_state_process() that still permitted reception even after closing the socket.

commit e8a80c6f upstream. vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt it as reported and analyzed by Josh. In fact, there is no good reason to mess with i_nlink of the moved file. We did it presumably to simulate linking into the new directory and unlinking from an old one. But the practical effect of this is disputable because fsck can possibly treat file as being properly linked into both directories without writing any error which is confusing. So we just stop increment-decrement games with i_nlink which also fixes the corruption. CC: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by:

commit 3a142a06 upstream. When the per cpu timer is marked CLOCK_EVT_FEAT_C3STOP, then we only can switch into oneshot mode, when the backup broadcast device supports oneshot mode as well. Otherwise we would try to switch the broadcast device into an unsupported mode unconditionally. This went unnoticed so far as the current available broadcast devices support oneshot mode. Seth unearthed this problem while debugging and working around an hpet related BIOS wreckage. Add the necessary check to tick_is_oneshot_available(). Reported-and-tested-by:

commit bcd2fde0 upstream. The expression while (running_total < sg_dma_len(sg)) does not take into account that the remaining data length can be less than sg_dma_len(sg). In that case, running_total can end up being greater than the total data length, so an extra TRB is counted. Changing the expression to while (running_total < sg_dma_len(sg) && running_total < temp) fixes that. This patch should be queued for stable kernels back to 2.6.31. Signed-off-by:

commit 5807795b upstream. Calculations like running_total = TRB_MAX_BUFF_SIZE - (sg_dma_address(sg) & (TRB_MAX_BUFF_SIZE - 1)); if (running_total != 0) num_trbs++; are incorrect, because running_total can never be zero, so the if() expression will never be true. I think the intention was that running_total be in the range of 0 to TRB_MAX_BUFF_SIZE-1, not 1 to TRB_MAX_BUFF_SIZE. So adding a running_total &= TRB_MAX_BUFF_SIZE - 1; fixes the problem.

commit a2490187 upstream. This makes it easier to spot some problems, which will be fixed by the next patch in the series. Also change dev_dbg to dev_err in check_trb_math(), so any math errors will be visible even when running with debug disabled.

commit 8f5f02c4 upstream. 'mdp' devices are md devices with preallocated device numbers for partitions. As such it is possible to mknod and open a partition before opening the whole device. this causes md_probe() to be called with a device number of a partition, which in-turn calls mddev_find with such a number. However mddev_find expects the number of a 'whole device' and does the wrong thing with partition numbers. So add code to mddev_find to remove the 'partition' part of a device number and just work with the 'whole device'.

commit 294f6cf4 upstream. The kernel automatically evaluates partition tables of storage devices. The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains a bug that causes a kernel oops on certain corrupted LDM partitions. A kernel subsystem seems to crash, because, after the oops, the kernel no longer recognizes newly connected storage devices. The patch changes ldm_parse_vmdb() to Validate the value of vblk_size.

commit 22bacca4 upstream. In several places, an epoll fd can call another file's ->f_op->poll() method with ep->mtx held. This is in general unsafe, because that other file could itself be an epoll fd that contains the original epoll fd. The code defends against this possibility in its own ->poll() method using ep_call_nested, but there are several other unsafe calls to ->poll elsewhere that can be made to deadlock. For example, the following simple program causes the call in ep_insert recursively call the original fd's ->poll, leading to deadlock: #include <unistd.h> #include <sys/epoll.h> int main(void) { int e1, e2, p[2]; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create(1); e2 = epoll_create(2); pipe(p); epoll_ctl(e2, EPOLL_CTL_ADD, e1, &evt); epoll_ctl(e1, EPOLL_CTL_ADD, p[0], &evt); write(p[1], p, sizeof p); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } On insertion, check whether the inserted file is itself a struct epoll, and if so, do a recursive walk to detect whether inserting this file would create a loop of epoll structures, which could lead to deadlock.

commit e1dc5157 upstream. I picked up a new Sierra usb 308 (At&t Shockwave) on 2/2011 and the vendor code is 0x0f3d Looking up vendor and product id's I see: 0f3d Airprime, Incorporated 0112 CDMA 1xEVDO PC Card, PC 5220 Sierra and Airprime are somehow related and I'm guessing the At&t usb 308 might be have some common hardware with the AirPrime SL809x.

commit 72a012ce upstream. My Galaxy Spica needs this quirk when in modem mode, otherwise it causes endless USB bus resets and is unusable in this mode. Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500 for the modem part. That's why in addition to this patch the visor driver must be prevented from binding to SPH-I500 ID, so ACM driver can do that. Signed-off-by:

commit acb52cb1 upstream. [USB]Add Samsung SGH-I500/Android modem ID switch to visor driver Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the modem part of some of their Android phones. At least Galaxy Spica is affected. This modem needs ACM driver and does not work with visor driver which binds the conflicting ID for SGH-I500. Because SGH-I500 is pretty an old hardware its best to add switch to visor driver in cause somebody still wants to use that phone with Linux. Note that this is needed only when using the Android phone as modem, not in USB storage or ADB mode. Signed-off-by:
