e7c0b59 ovl: warn instead of error if d_type is not supported overlay needs underlying fs to support d_type. Recently I put in a patch in to detect this condition and started failing mount if underlying fs did not support d_type. But this breaks existing configurations over kernel upgrade. Those who are running docker (partially broken configuration) with xfs not supporting d_type, are surprised that after kernel upgrade docker does not run anymore. https://github.com/docker/docker/issues/22937#issuecomment-229881315 So instead of erroring out, detect broken configuration and warn about it. This should allow existing docker setups to continue working after kernel upgrade.

6d037de MIPS: Fix possible corruption of cache mode by mprotect. The following testcase may result in a page table entries with a invalid CCA field being generated: static void *bindstack; static int sysrqfd; static void protect_low(int protect) { mprotect(bindstack, BINDSTACK_SIZE, protect); } static void sigbus_handler(int signal, siginfo_t * info, void *context) { void *addr = info->si_addr; write(sysrqfd, "x", 1); printf("sigbus, fault address %p (should not happen, but might)\n", addr); abort(); } static void run_bind_test(void) { unsigned int *p = bindstack; p[0] = 0xf001f001; write(sysrqfd, "x", 1); /* Set trap on access to p[0] */ protect_low(PROT_NONE); write(sysrqfd, "x", 1); /* Clear trap on access to p[0] */ protect_low(PROT_READ | PROT_WRITE | PROT_EXEC); write(sysrqfd, "x", 1); /* Check the contents of p[0] */ if (p[0] != 0xf001f001) { write(sysrqfd, "x", 1); /* Reached, but shouldn't be */ printf("badness, shouldn't happen but does\n"); abort(); } } int main(void) { struct sigaction sa; sysrqfd = open("/proc/sysrq-trigger", O_WRONLY); if (sigprocmask(SIG_BLOCK, NULL, &sa.sa_mask)) { perror("sigprocmask"); return 0; } sa.sa_sigaction = sigbus_handler; sa.sa_flags = SA_SIGINFO | SA_NODEFER | SA_RESTART; if (sigaction(SIGBUS, &sa, NULL)) { perror("sigaction"); return 0; } bindstack = mmap(NULL, BINDSTACK_SIZE, PROT_READ | PROT_WRITE | PROT_EXEC, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); if (bindstack == MAP_FAILED) { perror("mmap bindstack"); return 0; } printf("bindstack: %p\n", bindstack); run_bind_test(); printf("done\n"); return 0; } There are multiple ingredients for this: 1) PAGE_NONE is defined to _CACHE_CACHABLE_NONCOHERENT, which is CCA 3 on all platforms except SB1 where it's CCA 5. 2) _page_cachable_default must have bits set which are not set _CACHE_CACHABLE_NONCOHERENT. 3) Either the defective version of pte_modify for XPA or the standard version must be in used. However pte_modify for the 36 bit address space support is no affected. In that case additional bits in the final CCA mode may generate an invalid value for the CCA field. On the R10000 system where this was tracked down for example a CCA 7 has been observed, which is Uncached Accelerated. Fixed by: 1) Using the proper CCA mode for PAGE_NONE just like for all the other PAGE_* pte/pmd bits. 2) Fix the two affected variants of pte_modify. Further code inspection also shows the same issue to exist in pmd_modify which would affect huge page systems. Issue in pte_modify tracked down by Alastair Bridgewater, PAGE_NONE and pmd_modify issue found by me. The history of this goes back beyond Linus' git history. Chris Dearman's commit 351336929ccf222ae38ff0cb7a8dd5fd5c6236a0 ("[MIPS] Allow setting of the cache attribute at run time.") missed the opportunity to fix this but it was originally introduced in lmo commit d523832cf12007b3242e50bb77d0c9e63e0b6518 ("Missing from last commit.") and 32cc38229ac7538f2346918a09e75413e8861f87 ("New configuration option CONFIG_MIPS_UNCACHED.")

6343a21 locks: use file_inode() (Another one for the f_path debacle.) ltp fcntl33 testcase caused an Oops in selinux_file_send_sigiotask. The reason is that generic_add_lease() used filp->f_path.dentry->inode while all the others use file_inode(). This makes a difference for files opened on overlayfs since the former will point to the overlay inode the latter to the underlying inode. So generic_add_lease() added the lease to the overlay inode and generic_delete_lease() removed it from the underlying inode. When the file was released the lease remained on the overlay inode's lock list, resulting in use after free.

e06b933 namespace: update event counter when umounting a deleted dentry - m_start() in fs/namespace.c expects that ns->event is incremented each time a mount added or removed from ns->list. - umount_tree() removes items from the list but does not increment event counter, expecting that it's done before the function is called. - There are some codepaths that call umount_tree() without updating "event" counter. e.g. from __detach_mounts(). - When this happens m_start may reuse a cached mount structure that no longer belongs to ns->list (i.e. use after free which usually leads to infinite loop). This change fixes the above problem by incrementing global event counter before invoking umount_tree().

bfa3708 powerpc: Initialise pci_io_base as early as possible Commit d6a9996e84ac ("powerpc/mm: vmalloc abstraction in preparation for radix") turned kernel memory and IO addresses from #defined constants to variables initialised at runtime. On PA6T (pasemi) systems the setup_arch() machine call initialises the onboard PCI-e root-ports, and uses pci_io_base to do this, which is now before its value has been set, resulting in a panic early in boot before console IO is initialised. Move the pci_io_base initialisation to the same place as vmalloc ranges are set (hash__early_init_mmu()/radix__early_init_mmu()) - this is the earliest possible place we can initialise it.

a53e35d reset: Ensure drivers are explicit when requesting reset lines Phasing out generic reset line requests enables us to make some better decisions on when and how to (de)assert said lines. If an 'exclusive' line is requested, we know a device *requires* a reset and that it's preferable to act upon a request right away. However, if a 'shared' reset line is requested, we can reasonably assume sure that placing a device into reset isn't a hard requirement, but probably a measure to save power and is thus able to cope with not being asserted if another device is still in use. In order allow gentle adoption and not to forcing all consumers to move to the API immediately, causing administration headache between subsystems, this patch adds some temporary stand-in shim-calls. This will ease the burden at merge time and allow subsystems to migrate over to the new API in a more realistic time-frame.

d913d3a openvswitch: fix conntrack netlink event delivery Only the first and last netlink message for a particular conntrack are actually sent. The first message is sent through nf_conntrack_confirm when the conntrack is committed. The last one is sent when the conntrack is destroyed on timeout. The other conntrack state change messages are not advertised. When the conntrack subsystem is used from netfilter, nf_conntrack_confirm is called for each packet, from the postrouting hook, which in turn calls nf_ct_deliver_cached_events to send the state change netlink messages. This commit fixes the problem by calling nf_ct_deliver_cached_events in the non-commit case as well.

Under the stress scenarios, we may get into a state where (due to the weak ordering) several ramrod doorbells were written to the BAR with an out-of-order producer values. Need to change the barrier type to a write barrier to make sure that the write buffer is flushed after each doorbell.

b560f03 neigh: Explicitly declare RCU-bh read side critical section in neigh_xmit() neigh_xmit() expects to be called inside an RCU-bh read side critical section, and while one of its two current callers gets this right, the other one doesn't. More specifically, neigh_xmit() has two callers, mpls_forward() and mpls_output(), and while both callers call neigh_xmit() under rcu_read_lock(), this provides sufficient protection for neigh_xmit() only in the case of mpls_forward(), as that is always called from softirq context and therefore doesn't need explicit BH protection, while mpls_output() can be called from process context with softirqs enabled. When mpls_output() is called from process context, with softirqs enabled, we can be preempted by a softirq at any time, and RCU-bh considers the completion of a softirq as signaling the end of any pending read-side critical sections, so if we do get a softirq while we are in the part of neigh_xmit() that expects to be run inside an RCU-bh read side critical section, we can end up with an unexpected RCU grace period running right in the middle of that critical section, making things go boom. This patch fixes this impedance mismatch in the callee, by making neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that expects to be treated as an RCU-bh read side critical section, as this seems a safer option than fixing it in the callers.

889ad45 e1000e: keep VLAN interfaces functional after rxvlan off I've got a bug report about an e1000e interface, where a VLAN interface is set up on top of it: $ ip link add link ens1f0 name ens1f0.99 type vlan id 99 $ ip link set ens1f0 up $ ip link set ens1f0.99 up $ ip addr add 192.168.99.92 dev ens1f0.99 At this point, I can ping another host on vlan 99, ip 192.168.99.91. However, if I do the following: $ ethtool -K ens1f0 rxvlan off Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on again. I'm not sure if this is actually intended behavior, or if there's a lack of software VLAN stripping fallback, or what, but things continue to work if I simply don't call e1000e_vlan_strip_disable() if there are active VLANs (plagiarizing a function from the e1000 driver here) on the interface. Also slipped a related-ish fix to the kerneldoc text for e1000e_vlan_strip_disable here...

c041778 cfg80211: fix proto in ieee80211_data_to_8023 for frames without LLC header The PDU length of incoming LLC frames is set to the total skb payload size in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly includes the length of the IEEE 802.11 header. The resulting LLC frame header has a too large PDU length, causing the llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming skb, effectively breaking STP. Solve the problem by properly substracting the IEEE 802.11 frame header size from the PDU length, allowing the LLC processor to pick up the incoming control messages. Special thanks to Gerry Rozema for tracking down the regression and proposing a suitable patch.

a3d2e9f tcp: do not send too big packets at retransmit time Arjun reported a bug in TCP stack and bisected it to a recent commit. In case where we process SACK, we can coalesce multiple skbs into fat ones (tcp_shift_skb_data()), to lower write queue overhead, because we do not expect to retransmit these packets. However, SACK reneging can happen, forcing the sender to retransmit all these packets. If skb->len is above 64KB, we then send buggy IP packets that could hang TSO engine on cxgb4. Neal suggested to use tcp_tso_autosize() instead of tp->gso_segs so that we cook packets of optimal size vs TCP/pacing. Thanks to Arjun for reporting the bug and running the tests !

664a84d drm/i915: Refresh cached DP port register value on resume During hibernation the cached DP port register value will be left with whatever value we have there when we create the hibernation image. Currently that means the port (and eDP PLL) will be off in the cached value. However when we resume there is no guarantee that the value in the actual register will match the cached value. If i915 isn't loaded in the kernel that loads the hibernation image, the port may well be on (eg. left on by the BIOS). The encoder state readout does the right thing in this case and updates our encoder state to reflect the actual hardware state. However the post-resume modeset will then use the stale cached port register value in intel_dp_link_down() and potentially confuse the hardware. This was caught by the following assert WARNING: CPU: 3 PID: 5288 at ../drivers/gpu/drm/i915/intel_dp.c:2184 assert_edp_pll+0x99/0xa0 [i915] eDP PLL state assertion failure (expected on, current off) on account of the eDP PLL getting prematurely turned off when shutting down the port, since the DP_PLL_ENABLE bit wasn't set in the cached register value. Presumably I introduced this problem in commit 6fec76628333 ("drm/i915: Use intel_dp->DP in eDP PLL setup") as before that we didn't update the cached value after shuttting the port down. That's assuming the port got enabled at least once prior to hibernating. If that didn't happen then the cached value would still have been totally out of sync with reality (eg. first boot w/o eDP on, then hibernate, and then resume with eDP on). So, let's fix this properly and refresh the cached register value from the hardware register during resume. DDI platforms shouldn't use the cached value during port disable at least, so shouldn't have this particular issue. They might still have issues if we skip the initial modeset and then try to retrain the link or something. But untangling this DP vs. DDI mess is a bigger topic, so let's jut punt on DDI for now.

d10f0b3 Merge branch 'batman-adv-fixes' Sven Eckelmann says: ==================== batman-adv: Fixes for Linux 4.7 Antonio currently seems to be occupied. This is currently rather unfortunate because there are patches waiting in the batman-adv development repository maint(enance) branch [1] since up to 6 weeks. I am now getting asked when these patches will hit the distribution kernels and therefore decided to submit these patches directly to netdev. The patch from Simon works around the problem that warnings could be triggered in the translation table code via packets using a VLAN not configured on the target host. This warning was replaced with a rate limited info message. Ben Hutchings found an superfluous batadv_softif_vlan_put in the error handling code of the translation table while he backported the "batman-adv: Fix reference counting of vlan object for tt_local_entry" patch to the stable kernels. He noticed correctly that this batadv_softif_vlan_put should also have been removed by the said patch. The most requested fix at the moment is related to a double free in the translation table code. It is a race condition which mostly happens on systems with multiple cores and multiple network interface attached to batman-adv. Two Freifunk communities which were haunted by weird crashes (with backtraces reporting problems in other parts of the kernel) were kind enough to test this patch. They reported that there systems are now running stable after applying this patch. An invalid memory access was detected in the batadv_icmp_packet_rr handling code when receiving a skbuff with fragments. The last patch is fixing a memory leak when the interface is removed via .dellink. The code to fix it was copied from the code handling the legacy sysfs interface to remove netdevices from a batman-adv netdevice. There are still 28 patches in the development tree for v4.8 but I will leave them to Antonio because these are cleanups and features and therefore for net- next. ==================== Signed-off-by: David S.
