commit bd329e12 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") added a test for a CDC MBIM altsetting, implementing the cdc_ncm part of MBIM backward compatibility support. This intentionally made the driver behave differently for CDC NCM devices with 2 alternate settings for the Communication interface, depending on whether or not CONFIG_USB_NET_CDC_MBIM was enabled. This is correct iff alternate setting #1 really *is* a MBIM setting. If not, then NCM probing will use a different altsetting than before, possibly causing probing failures depending on CONFIG_USB_NET_CDC_MBIM. Fix by setting the altsetting back to default after the test, restoring the previous behaviour for non MBIM devices. This bug causes probing of Huawei E3276 devices to fail when the MBIM driver is enabled, because these devices have a second alternate setting with no CDC functional descriptors.

由 Daniel Borkmann 提交于
We walk through the bind address list and try to get the best source address for a given destination. However, currently, we take the 'continue' path of the loop when an entry is invalid (!laddr->valid) *and* the entry state does not equal SCTP_ADDR_SRC (laddr->state != SCTP_ADDR_SRC). Thus, still, invalid entries with SCTP_ADDR_SRC might not 'continue' as well as valid entries with SCTP_ADDR_{NEW, SRC, DEL}, with a possible false baddr and matchlen as a result, causing in worst case dst route to be false or possibly NULL. This test should actually be a '||' instead of '&&'. But lets fix it and make this a bit easier to read by having the condition the same way as similarly done in sctp_v4_get_dst.

An entry in DAT with the hashed position of 0 can cause a NULL pointer dereference when the first entry is checked by batadv_choose_next_candidate. This first candidate automatically has the max value of 0 and the max_orig_node of NULL. Not checking max_orig_node for NULL in batadv_is_orig_node_eligible will lead to a NULL pointer dereference when checking for the lowest address.

A user reported the following oops when a backup process reads /proc/kcore: BUG: unable to handle kernel paging request at ffffbb00ff33b000 IP: [<ffffffff8103157e>] kern_addr_valid+0xbe/0x110 [...] Call Trace: [<ffffffff811b8aaa>] read_kcore+0x17a/0x370 [<ffffffff811ad847>] proc_reg_read+0x77/0xc0 [<ffffffff81151687>] vfs_read+0xc7/0x130 [<ffffffff811517f3>] sys_read+0x53/0xa0 [<ffffffff81449692>] system_call_fastpath+0x16/0x1b Investigation determined that the bug triggered when reading system RAM at the 4G mark. On this system, that was the first address using 1G pages for the virt->phys direct mapping so the PUD is pointing to a physical address, not a PMD page. The problem is that the page table walker in kern_addr_valid() is not checking pud_large() and treats the physical address as if it was a PMD. If it happens to look like pmd_none then it'll silently fail, probably returning zeros instead of real data. If the data happens to look like a present PMD though, it will be walked resulting in the oops above. This patch adds the necessary pud_large() check. Unfortunately the problem was not readily reproducible and now they are running the backup program without accessing /proc/kcore so the patch has not been validated but I think it makes sense.

The designed workflow for the caches in kmemcg is: register it with memcg_register_cache() if kmemcg is already available or later on when a new kmemcg appears at memcg_update_cache_sizes() which will handle all caches in the system. The caches created at boot time will be handled by the later, and the memcg-caches as well as any system caches that are registered later on by the former. There is a bug, however, in memcg_register_cache: we correctly set up the array size, but do not mark the cache as a root cache. This means that allocations for any cache appearing late in the game will see memcg->memcg_params->is_root_cache == false, and in particular, trigger VM_BUG_ON(!cachep->memcg_params->is_root_cache) in __memcg_kmem_cache_get. The obvious fix is to include the missing assignment.

RSC is only supported with IPv4/TCP frames only. As such we can simplify the fix and avoid the unnecessary move of eth_type_trans.

The band field for the supported channels were left unpopulated, making them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels. This resulted in null pointer accesses if anything tries to access wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

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.

When a HP ProLiant DL980 G7 Server boots a regular kernel, there will be intermittent lost interrupts which could result in a hang or (in extreme cases) data loss. The reason is that this system only supports x2apic physical mode, while the kernel boots with a logical-cluster default setting. This bug can be worked around by specifying the "x2apic_phys" or "nox2apic" boot option, but we want to handle this system without requiring manual workarounds. The BIOS sets ACPI_FADT_APIC_PHYSICAL in FADT table. As all apicids are smaller than 255, BIOS need to pass the control to the OS with xapic mode, according to x2apic-spec, chapter 2.9. Current code handle x2apic when BIOS pass with xapic mode enabled: When user specifies x2apic_phys, or FADT indicates PHYSICAL: 1. During madt oem check, apic driver is set with xapic logical or xapic phys driver at first. 2. enable_IR_x2apic() will enable x2apic_mode. 3. if user specifies x2apic_phys on the boot line, x2apic_phys_probe() will install the correct x2apic phys driver and use x2apic phys mode. Otherwise it will skip the driver will let x2apic_cluster_probe to take over to install x2apic cluster driver (wrong one) even though FADT indicates PHYSICAL, because x2apic_phys_probe does not check FADT PHYSICAL. Add checking x2apic_fadt_phys in x2apic_phys_probe() to fix the problem.

When trying to connect to an AP that advertises HT but not VHT, the mac80211 code erroneously uses the configuration from the AP as is instead of checking it against regulatory and local capabilities. This can lead to using an invalid or even inexistent channel (like 11/HT40+). Additionally, the return flags from downgrading must be ORed together, to collect them from all of the downgrades. Also clarify the message. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

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.
