2012-10-18ipv4: Fix flushing of cached routing informationsSteffen Klassert
Currently we can not flush cached pmtu/redirect informations via the ipv4_sysctl_rtcache_flush sysctl. We need to check the rt_genid of the old route and reset the nh exeption if the old route is expired when we bind a new route to a nh exeption.

git://git.infradead.org/users/dhowells/linux-headers Pull misc UAPI fixes from David Howells: "They do a number of things: (1) Import a patch from Catalin Marinas to extend the generic-y in Kbuild facility to uapi directories. (2) Make arch/tile's ucontext.h file use (1) and remove the header-y line from the kernel internal side of things. (3) Remove some now-empty conditional bits from include/linux/Kbuild. The contents got moved to the UAPI side of things along with new conditionals. (4) Deal with now-empty files: (a) Empty Kbuild files under include/ get removed. (b) Empty Kbuild files under arch/ get comments to hold them as they are likely to end up with generic-y or genhdr-y lines. Deleting them appears to work if we want to go that route. (c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the patch program from deleting that, and made the arches with empty kvm_para.h uapi files use that instead of having their own files. (d) Put comments into four other empty uapi/ headers to prevent the patch program from deleting them. A question: Is this the right way to deal with the now-empty Kbuild files? The ones under include/ are unlikely to be used - even for generated files, I think - so getting rid of them is probably okay. Once all the bits are in, we can probably remove all the Kbuild files under include/ that aren't also under include/uapi/.

Place comments in: arch/mips/include/asm/Kbuild arch/tile/include/arch/Kbuild to make them non-empty so that the patch program doesn't remove them when it reduces them to nothing. Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.

2012-10-17UAPI: Remove empty non-UAPI Kbuild filesDavid Howells
Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <dhowells@redhat.com>

Looking in: /usr/include/linux/irqnr.h there's nothing there but a header reinclusion guard and a comment. So just stick a comment in there as a placeholder.

Torsten Luettgert bisected TEE regression starting with commit f8126f1d5136be1 (ipv4: Adjust semantics of rt->rt_gateway.)

2012-10-17mm, mempolicy: fix printing stack contents in numa_mapsDavid Rientjes
When reading /proc/pid/numa_maps, it's possible to return the contents of the stack where the mempolicy string should be printed if the policy gets freed from beneath us. This happens because mpol_to_str() may return an error the stack-allocated buffer is then printed without ever being stored. There are two possible error conditions in mpol_to_str(): - if the buffer allocated is insufficient for the string to be stored, and - if the mempolicy has an invalid mode. The first error condition is not triggered in any of the callers to mpol_to_str(): at least 50 bytes is always allocated on the stack and this is sufficient for the string to be written. A future patch should convert this into BUILD_BUG_ON() since we know the maximum strlen possible, but that's not -rc material. The second error condition is possible if a race occurs in dropping a reference to a task's mempolicy causing it to be freed during the read(). The slab poison value is then used for the mode and mpol_to_str() returns -EINVAL. This race is only possible because get_vma_policy() believes that mm->mmap_sem protects task->mempolicy, which isn't true. The exit path does not hold mm->mmap_sem when dropping the reference or setting task->mempolicy to NULL: it uses task_lock(task) instead. Thus, it's required for the caller of a task mempolicy to hold task_lock(task) while grabbing the mempolicy and reading it. Callers with a vma policy store their mempolicy earlier and can simply increment the reference count so it's guaranteed not to be freed.

2012-10-16sparc64: Fix bit twiddling in sparc_pmu_enable_event().David S. Miller
There was a serious disconnect in the logic happening in sparc_pmu_disable_event() vs. sparc_pmu_enable_event(). Event disable is implemented by programming a NOP event into the PCR. However, event enable was not reversing this operation. Instead, it was setting the User/Priv/Hypervisor trace enable bits. That's not sparc_pmu_enable_event()'s job, that's what sparc_pmu_enable() and sparc_pmu_disable() do . The intent of sparc_pmu_enable_event() is clear, since it first clear out the event type encoding field. So fix this by OR'ing in the event encoding rather than the trace enable bits.

Commit 1d5783030a1 (ipv6/addrconf: speedup /proc/net/if_inet6 filling) added bugs hiding some devices from if_inet6 and breaking applications. "ip -6 addr" could still display all IPv6 addresses, while "ifconfig -a" couldnt. One way to reproduce the bug is by starting in a shell : unshare -n /bin/bash ifconfig lo up And in original net namespace, lo device disappeared from if_inet6 Reported-by: Jan Hinnerk Stosch <janhinnerk.stosch@gmail.com> Tested-by: Jan Hinnerk Stosch <janhinnerk.stosch@gmail.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Mihai Maruseac <mihai.maruseac@gmail.com> Signed-off-by: David S.

2012-10-16qeth: fix deadlock between recovery and bonding driverStefan Raspl
The recovery thread, when failing, tears down the respective interface. To do so, it needs to obtain the rtnl lock first, as the interface configuration is changed. If another process tries to modify an interface setting at the same time, that process can obtain the rtnl lock first, but the respective callback in the qeth driver will block until recovery has completed - which cannot happen since the calling process already obtained it. In one particular case, the bonding driver acquired the rtnl lock to modify the card's MAC address, while the recovery failed at the same time due to the card being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock) was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock. This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the lock cannot be obtained, the interface will be left up, but the card state remains in CARD_STATE_RECOVER, which will prevent any further activities on the card.

In vlan_uses_dev() check for number of vlan devs rather than existence of vlan_info. The reason is that vlan id 0 is there without appropriate vlan dev on it by default which prevented from enslaving vlan challenged dev.
