commit cbb4be65 upstream. Fix potential null-pointer dereference at probe by making sure that the required endpoints are present. The whiteheat driver assumes there are at least five pairs of bulk endpoints, of which the final pair is used for the "command port". An attempt to bind to an interface with fewer bulk endpoints would currently lead to an oops. Fixes CVE-2015-5257.

commit 274d8352 upstream. Since 9eb1e57f drm/dp/mst: make sure mst_primary mstb is valid in work function we validate the mstb structs in the work function, and doing that takes a reference. So we should never get here with the work function running using the mstb device, only if the work function hasn't run yet or is running for another mstb. So we don't need to sync the work here, this was causing lockdep spew as below.

commit df4839fd upstream. output ports should always have a connector, unless in the rare case connector allocation fails in the driver. In this case we only need to teardown the pdt, and free the struct, and there is no need to send a hotplug msg. In the case were we add the port to the destroy list we need to send a hotplug if we destroy any connectors, so userspace knows to reprobe stuff. this patch also handles port->connector allocation failing which should be a rare event, but makes the code consistent.

commit da168d81 upstream. I've done some extensive history digging across libdrm, mesa and xf86-video-{intel,nouveau,ati}. The only potential user of this with kms drivers I could find was ttmtest, which once used drmGetLock still. But that mistake was quickly fixed up. Even the intel xvmc library (which otherwise was really good with using dri1 stuff in kms mode) managed to never take the hw lock for dri2 (and hence kms). Hence it should be save to unconditionally disallow this.

commit cd67d226 upstream. The VBT MIPI Sequence Block version 3 has forward incompatible changes: First, the block size in the header has been specified reserved, and the actual size is a separate 32-bit value within the block. The current find_section() function to will only look at the size in the block header, and, depending on what's in that now reserved size field, continue looking for other sections in the wrong place. Fix this by taking the new block size field into account. This will ensure that the lookups for other sections will work properly, as long as the new 32-bit size does not go beyond the opregion VBT mailbox size. Second, the contents of the block have been completely changed. Gracefully refuse parsing the yet unknown data version.

commit 646200a0 upstream. The error paths in set_file_size for cifs and smb3 are incorrect. In the unlikely event that a server did not support set file info of the file size, the code incorrectly falls back to trying SMBWriteX (note that only the original core SMB Write, used for example by DOS, can set the file size this way - this actually does not work for the more recent SMBWriteX). The idea was since the old DOS SMB Write could set the file size if you write zero bytes at that offset then use that if server rejects the normal set file info call. Fortunately the SMBWriteX will never be sent on the wire (except when file size is zero) since the length and offset fields were reversed in the two places in this function that call SMBWriteX causing the fall back path to return an error. It is also important to never call an SMB request from an SMB2/sMB3 session (which theoretically would be possible, and can cause a brief session drop, although the client recovers) so this should be fixed. In practice this path does not happen with modern servers but the error fall back to SMBWriteX is clearly wrong.

commit 24311f88 upstream. When a read delegation is being recalled, and we're reclaiming the cached opens, we need to make sure that we only reclaim read-only modes. A previous attempt to do this, relied on retrieving the delegation type from the nfs4_opendata structure. Unfortunately, as Kinglong pointed out, this field can only be set when performing reboot recovery. Furthermore, if we call nfs4_open_recover(), then we end up clobbering the state->flags for all modes that we're not recovering... The fix is to have the delegation recall code pass this information to the recovery call, and then refactor the recovery code so that nfs4_open_delegation_recall() does not need to call nfs4_open_recover().

commit 06423121 upstream. When resolving regulator-regulator supplies we ignore probe deferral returns from regulator_dev_lookup() (such as are generated for DT when we can see a supply is registered) and just fall back to the dummy regulator if there are full constraints (as is the case for DT). This means that probe deferral is broken for DT systems, fix that by paying attention to -EPROBE_DEFER return codes like we do -ENODEV. A further patch will simplify this further, this is a minimal fix for the specific issue.

commit ba378ca9 upstream. Fix lookup of existing match/target structures in the corresponding list by skipping the family check if NFPROTO_UNSPEC is used.

commit 9cf94eab upstream. Commit 0838aa7f ("netfilter: fix netns dependencies with conntrack templates") migrated templates to the new allocator api, but forgot to update error paths for them in CT and synproxy to use nf_ct_tmpl_free() instead of nf_conntrack_free(). Due to that, memory is being freed into the wrong kmemcache, but also we drop the per net reference count of ct objects causing an imbalance. In Brad's case, this leads to a wrap-around of net->ct.count and thus lets __nf_conntrack_alloc() refuse to create a new ct object: [ 10.340913] xt_addrtype: ipv6 does not support BROADCAST matching [ 10.810168] nf_conntrack: table full, dropping packet [ 11.917416] r8169 0000:07:00.0 eth0: link up [ 11.917438] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 12.815902] nf_conntrack: table full, dropping packet [ 15.688561] nf_conntrack: table full, dropping packet [ 15.689365] nf_conntrack: table full, dropping packet [ 15.690169] nf_conntrack: table full, dropping packet [ 15.690967] nf_conntrack: table full, dropping packet [...] With slab debugging, it also reports the wrong kmemcache (kmalloc-512 vs. nf_conntrack_ffffffff81ce75c0) and reports poison overwrites, etc. Thus, to fix the problem, export and use nf_ct_tmpl_free() instead.

commit bf798657 upstream. nft_type_to_reg() needs to return the register in the new 32 bit addressing, otherwise we hit EINVAL when using mappings.

commit a9de9777 upstream. The convention in nfnetlink is to use network byte order in every header field as well as in the attribute payload. The initial version of the batching infrastructure assumes that res_id comes in host byte order though. The only client of the batching infrastructure is nf_tables, so let's add a workaround to address this inconsistency. We currently have 11 nfnetlink subsystems according to NFNL_SUBSYS_COUNT, so we can assume that the subsystem 2560, ie. htons(10), will not be allocated anytime soon, so it can be an alias of nf_tables from the nfnetlink batching path when interpreting the res_id field. Based on original patch from Florian Westphal.

commit 18e1db67 upstream. 230ac490 introduced a dependency to CONFIG_IPV6 which breaks bridging of IPv6 packets on a bridge with CONFIG_IPV6=n. Sysctl entry /proc/sys/net/bridge/bridge-nf-call-ip6tables defaults to 1, for this reason packets are handled by br_nf_pre_routing_ipv6(). When compiled with CONFIG_IPV6=n this function returns NF_DROP but should return NF_ACCEPT to let packets through. Change CONFIG_IPV6=n br_nf_pre_routing_ipv6() return value to NF_ACCEPT. Tested with a simple bridge with two interfaces and IPv6 packets trying to pass from host on left side to host on right side of the bridge.

commit 042745ee upstream. Commit 3a0f9aae ("dm raid: round region_size to power of two") intended to make sure that the default region size is a power of two. However, the logic in that commit is incorrect and sets the variable region_size to 0 or 1, depending on whether min_region_size is a power of two. Fix this logic, using roundup_pow_of_two(), so that region_size is properly rounded up to the next power of two.

commit 66eefe5d upstream. Calling e.g. blk_queue_max_hw_sectors() after calls to disk_stack_limits() discards the settings determined by disk_stack_limits(). So we need to make those calls first.

commit 199dc6ed upstream. When a (e.g.) RAID5 array is reshaped to RAID0, the updating of queue parameters (e.g. max number of sectors per bio) is done in the wrong place. It should be part of ->run, but it is actually part of ->takeover. This means it happens before level_store() calls: blk_set_stacking_limits(&mddev->queue->limits); and so it ineffective. This can lead to errors from underlying devices. So move all the relevant settings out of create_stripe_zones() and into raid0_run(). As this can lead to a bug-on it is suitable for any -stable kernel which supports reshape to RAID0. So 2.6.35 or later. As the bug has been present for five years there is no urgency, so no need to rush into -stable.
