ipv6_add_addr allocates a struct inet6_ifaddr and a dstentry, but it doesn't install the dstentry in ifa->rt until after it releases the addrconf_hash_lock. This means other CPUs will be able to see the new address while it hasn't been initialized completely yet. One possible fix would be to grab the ifp->lock spinlock when creating the address struct; a simpler fix is to just move the assignment. Acked-by: jbeulich@novell.com Acked-by: okir@suse.de Acked-by:

When I tested Linux kernel 2.6.17.7 about statistics "ipv6IfStatsInAddrErrors", found that this counter couldn't increase correctly. The criteria is RFC2465: ipv6IfStatsInAddrErrors OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of input datagrams discarded because the IPv6 address in their IPv6 header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (e.g., ::0) and unsupported addresses (e.g., addresses with unallocated prefixes). For entities which are not IPv6 routers and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address." ::= { ipv6IfStatsEntry 5 } When I send packet to host with destination that is ether invalid address(::0) or unsupported addresses(1::1), the Linux kernel just discard the packet, and the counter doesn't increase(in the function ip6_pkt_discard).

Patch from Lennert Buytenhek On armv4t systems, we have always compiled the kernel with -march=armv4 instead of -march=armv4t, which means that any use of bx will bomb out. Commit ba9b5d76 introduced the use of bx in the kernel, which means we need to compile with -march=armv4t on armv4t systems now. Signed-off-by:

Unlike the other tty comment patch this one has code changes. Specifically it limits the queue size for a tty to 64K characters (128Kbytes) worst case even if the tty is ignoring tty->throttle. This is because certain drivers don't honour the throttle value correctly, although it is a useful safeguard anyway. Signed-off-by:

cpuset_excl_nodes_overlap always returns 0 if current is exiting. This caused customer's systems to panic in the OOM killer when processes were having trouble getting memory for the final put_user in mm_release. Even though there were lots of processes to kill. Change to returning 1 in this case. This achieves parity with !CONFIG_CPUSETS case, and was observed to fix the problem. Signed-off-by:

JBD currently allocates commit and frozen buffers from slabs. With CONFIG_SLAB_DEBUG, its possible for an allocation to cross the page boundary causing IO problems. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200127 So, instead of allocating these from regular slabs - manage allocation from its own slabs and disable slab debug for these slabs.

Change the list of cpus allowed to tasks in the top (root) cpuset to dynamically track what cpus are online, using a CPU hotplug notifier. Make this top cpus file read-only. On systems that have cpusets configured in their kernel, but that aren't actively using cpusets (for some distros, this covers the majority of systems) all tasks end up in the top cpuset. If that system does support CPU hotplug, then these tasks cannot make use of CPUs that are added after system boot, because the CPUs are not allowed in the top cpuset. This is a surprising regression over earlier kernels that didn't have cpusets enabled. In order to keep the behaviour of cpusets consistent between systems actively making use of them and systems not using them, this patch changes the behaviour of the 'cpus' file in the top (root) cpuset, making it read only, and making it automatically track the value of cpu_online_map. Thus tasks in the top cpuset will have automatic use of hot plugged CPUs allowed by their cpuset. Thanks to Anton Blanchard and Nathan Lynch for reporting this problem, driving the fix, and earlier versions of this patch. Signed-off-by:

If we - shut down a clean array, - restart with one (or more) drive(s) missing - make some changes - pause, so that they array gets marked 'clean', the event count on the superblock of included drives will be the same as that of the removed drives. So adding the removed drive back in will cause it to be included with no resync. To avoid this, we only update the eventcount backwards when the array is not degraded. In this case there can (should) be no non-connected drives that we can get confused with, and this is the particular case where updating-backwards is valuable. Signed-off-by:

1) When we allocated last fragment in ufs_truncate, we read page, check if block mapped to address, and if not trying to allocate it. This is wrong behaviour, fragment may be NOT allocated, but mapped, this happened because of "block map" function not checked allocated fragment or not, it just take address of the first fragment in the block, add offset of fragment and return result, this is correct behaviour in almost all situation except call from ufs_truncate. 2) Almost all implementation of UFS, which I can investigate have such "defect": if you have full disk, and try truncate file, for example 3GB to 2MB, and have hole in this region, truncate return -ENOSPC. I tried evade from this problem, but "block allocation" algorithm is tied to right value of i_lastfrag, and fix of this corner case may slow down of ordinaries scenarios, so this patch makes behavior of "truncate" operations similar to what other UFS implementations do.

On UFS, this scenario: open(O_TRUNC) lseek(1024 * 1024 * 80) write("A") lseek(1024 * 2) write("A") may cause access to invalid address. This happened because of "goal" is calculated in wrong way in block allocation path, as I see this problem exists also in 2.4. We use construction like this i_data[lastfrag], i_data array of pointers to direct blocks, indirect and so on, it has ceratain size ~20 elements, and lastfrag may have value for example 40000. Also this patch fixes related to handling such scenario issues, wrong zeroing metadata, in case of block(not fragment) allocation, and wrong goal calculation, when we allocate block Signed-off-by: -

To handle the earlier bogus ENOSPC error caused by filesystem full of block reservation, current code falls back to non block reservation, starts to allocate block(s) from the goal allocation block group as if there is no block reservation. Current code needs to re-load the corresponding block group descriptor for the initial goal block group in this case. The patch fixes this. Signed-off-by:

futex_find_get_task: if (p->state == EXIT_ZOMBIE || p->exit_state == EXIT_ZOMBIE) return NULL; I can't understand this. First, p->state can't be EXIT_ZOMBIE. The ->exit_state check looks strange too. Sub-threads or tasks whose ->parent ignores SIGCHLD go directly to EXIT_DEAD state (I am ignoring a ptrace case). Why EXIT_DEAD tasks should be ok? Yes, EXIT_ZOMBIE is more important (a task may stay zombie for a long time), but this doesn't mean we should explicitely ignore other EXIT_XXX states. Signed-off-by:

When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure). Signed-off-by:
