commit (32f53760 netfilter: nf_ct_helper: disable automatic helper re-assignment of different type) broke transparent proxy scenarios. For example, initial helper lookup might yield "ftp" (dport 21), while re-lookup after REDIRECT yields "ftp-2121". This causes the autoassign code to toss the ftp helper, even though these are just different instances of the same helper. Change the test to check for the helper function address instead of the helper address, as suggested by Pablo.

Userspace can cause kernel panic by not specifying orig/reply tuple: kernel will create a tuple with random stack values. Problem is that tuple.dst.dir will be random, too, which causes nf_ct_tuplehash_to_ctrack() to return garbage.

Spanning Tree Protocol packets should have always been marked as control packets, this causes them to get queued in the high prirority FIFO. As Radia Perlman mentioned in her LCA talk, STP dies if bridge gets overloaded and can't communicate. This is a long-standing bug back to the first versions of Linux bridge.

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter/IPVS fixes for 3.8-rc7, they are: * Fix oops in IPVS state-sync due to releasing a random memory area due to unitialized pointer, from Dan Carpenter. * Fix SCTP flow establishment due to bad checksumming mangling in IPVS, from Daniel Borkmann. * Three fixes for the recently added IPv6 NPT, all from YOSHIFUJI Hideaki, with an amendment collapsed into those patches from Ulrich Weber. They fiix adjustment calculation, fix prefix mangling and ensure LSB of prefixes are zeroes (as required by RFC). Specifically, it took me a while to validate the 1's complement arithmetics/ checksumming approach in the IPv6 NPT code. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Michael S. Tsirkin says: ==================== At the moment, macvtap crashes are observed if macvtap is attached to an interface with LRO enabled. The crash in question is BUG() in macvtap_skb_to_vnet_hdr. This happens because several drivers set gso_size but not gso_type in incoming skbs. This didn't use to be the case: with intel cards on 3.2 and older kernels, with qlogic - on 3.4 and older kernels, so it's a regression if not a recent one. The following patches fix this for qlogic, broadcom and intel drivers. I tested that the patch fixes the crash for ixgbe but don't have qlogic/broadcom hardware to test. I also only tested TCPv4. Please review, and consider for 3.8. Changes from v1: - added missing htons as suggested by Eric - backported the relevant bits from cbf1de72 for bnx2x ==================== Signed-off-by: NDavid S.

In LRO mode, bnx2x set gso_size but not gso type. This leads to crashes in macvtap. Commit cbf1de72 queued for 3.9 includes a more complete fix. This is a minimal patch to avoid the crash, for 3.8.

Pull ARM fixes from Russell King: "I was going to hold these off until v3.8 was out, and send them with a stable tag, but as everyone else is pushing much bigger fixes which Linus is accepting, let's save people from the hastle of having to patch v3.8 back into working or use a stable kernel. Looking at the diffstat, this really is high value for its size; this is miniscule compared to how the -rc6 to tip diffstat currently looks. So, four patches in this set: - Punit Agrawal reports that the kernel no longer boots on MPCore due to a new assumption made in the GIC code which isn't true of earlier GIC designs. This is the biggest change in this set. - Punit's boot log also revealed a bunch of WARN_ON() dumps caused by the DT-ification of the GIC support without fixing up non-DT Realview - which now sees a greater number of interrupts than it did before. - A fix for the DMA coherent code from Marek which uses the wrong check for atomic allocations; this can result in spinlock lockups or other nasty effects. - A fix from Will, which will affect all Android based platforms if not applied (which use the 2G:2G VM split) - this causes particularly 'make' to misbehave unless this bug is fixed." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned ARM: DMA mapping: fix bad atomic test ARM: realview: ensure that we have sufficient IRQs available ARM: GIC: fix GIC cpumask initialization

This is the best short-term fix for this, a longer term fix has been implemented in net-next. 11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops.

From Ian Campbell. 18) SCTP authentication keys should be cleared out and released with kzfree(), from Daniel Borkmann. 19) L2TP is a bit too clever trying to maintain skb->truesize, and ends up corrupting socket memory accounting to the point where packet sending is halted indefinitely.

In sctp_setsockopt_auth_key, we create a temporary copy of the user passed shared auth key for the endpoint or association and after internal setup, we free it right away. Since it's sensitive data, we should zero out the key before returning the memory back to the allocator. Thus, use kzfree instead of kfree, just as we do in sctp_auth_key_put().

We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the iphase atm device driver, which causes the compile error below. Unfortunately the s390 typedef can't be renamed, since it's a user visible api, nor can I change the include order in s390 code to avoid the conflict. So simply rename the iphase typedef to a new name.

We have received multiple reports of mmap failures when running with a 2:2 vm split. These manifest as either -EINVAL with a non page-aligned address (ending 0xaaa) or a SEGV, depending on the application. The issue is commonly observed in children of make, which appears to use bottom-up mmap (assumedly because it changes the stack rlimit). Further investigation reveals that this regression was triggered by 394ef640 ("mm: use vm_unmapped_area() on arm architecture"), whereby TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing get_unmapped_area to choke on misaligned addressed. This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of TASK_SIZE and explicitly aligns the result to 16M, matching the other end of the heap.

Some early GIC implementations return zero for the first distributor CPU routing register. This means we can't rely on that telling us which CPU interface we're connected to. We know that these platforms implement PPIs for IRQs 29-31 - but we shouldn't assume that these will always be populated. So, instead, scan for a non-zero CPU routing register in the first 32 IRQs and use that as our CPU mask.

Ian Campbell says: ==================== The Xen netback implementation contains a couple of flaws which can allow a guest to cause a DoS in the backend domain, potentially affecting other domains in the system. CVE-2013-0216 is a failure to sanity check the ring producer/consumer pointers which can allow a guest to cause netback to loop for an extended period preventing other work from occurring. CVE-2013-0217 is a memory leak on an error path which is guest triggerable. The following series contains the fixes for these issues, as previously included in Xen Security Advisory 39: http://lists.xen.org/archives/html/xen-announce/2013-02/msg00001.html Changes in v2: - Typo and block comment format fixes - Added stable Cc ==================== Signed-off-by: NDavid S.

A buggy or malicious frontend should not be able to confuse netback. If we spot anything which is not as it should be then shutdown the device and don't try to continue with the ring in a potentially hostile state. Well behaved and non-hostile frontends will not be penalised. As well as making the existing checks for such errors fatal also add a new check that ensures that there isn't an insane number of requests on the ring (i.e. more than would fit in the ring). If the ring contains garbage then previously is was possible to loop over this insane number, getting an error each time and therefore not generating any more pending requests and therefore not exiting the loop in xen_netbk_tx_build_gops for an externded period. Also turn various netdev_dbg calls which no precipitate a fatal error into netdev_err, they are rate limited because the device is shutdown afterwards. This fixes at least one known DoS/softlockup of the backend domain.
