2016-07-06init/Kconfig: keep Expert users menu togetherHEADmasterRandy Dunlap1-0/+1
The "expert" menu was broken (split) such that all entries in it after KALLSYMS were displayed in the "General setup" area instead of in the "Expert users" area. Fix this by adding one kconfig dependency. Yes, the Expert users menu is fragile. Problems like this have happened several times in the past. I will attempt to isolate the Expert users menu if there is interest in that.

2016-07-05ipv6: Fix mem leak in rt6i_pcpuMartin KaFai Lau1-0/+1
It was first reported and reproduced by Petr (thanks!) in free_percpu(rt->rt6i_pcpu) used to always happen in ip6_dst_destroy(). However, after fixing a deadlock bug in commit 9c7370a166b4 ("ipv6: Fix a potential deadlock when creating pcpu rt"), free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL. It is worth to note that rt6i_pcpu is protected by table->tb6_lock. kmemleak somehow did not report it. We nailed it down by observing the pcpu entries in /proc/vmallocinfo (first suggested by Hannes, thanks!).

2016-07-05bonding: fix enslavement slave link notificationsAviv Heller1-0/+1
Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic.

2016-07-04cdc_ncm: workaround for EM7455 "silent" data interfaceBjørn Mork1-0/+7
Several Lenovo users have reported problems with their Sierra Wireless EM7455 modem. The driver has loaded successfully and the MBIM management channel has appeared to work, including establishing a connection to the mobile network. But no frames have been received over the data interface. The problem affects all EM7455 and MC7455, and is assumed to affect other modems based on the same Qualcomm chipset and baseband firmware. Testing narrowed the problem down to what seems to be a firmware timing bug during initialization. Adding a short sleep while probing is sufficient to make the problem disappear. Experiments have shown that 1-2 ms is too little to have any effect, while 10-20 ms is enough to reliably succeed.

The user timer tu->qused counter may go to a negative value when multiple concurrent reads are performed since both the check and the decrement of tu->qused are done in two individual locked contexts. This results in bogus read outs, and the endless loop in the user-space side.

2016-07-03ovl: warn instead of error if d_type is not supportedVivek Goyal1-5/+7
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. So instead of erroring out, detect broken configuration and warn about it. This should allow existing docker setups to continue working after kernel upgrade.

2016-07-02enc28j60: Fix race condition in enc28j60 driverSergio Valverde1-2/+5
The interrupt worker code for the enc28j60 relies only on the TXIF flag to determinate if the packet transmission was completed. However the datasheet specifies in section 12.1.3 that TXERIF will clear the TXRTS after a transmit abort. Also in section 12.1.4 that TXIF will be set when TXRTS transitions from '1' to '0'. Therefore the TXIF flag is enabled during transmission errors. This causes a race condition, since the worker code will invoke enc28j60_tx_clear() -> netif_wake_queue(), potentially invoking the ndo_start_xmit function to send a new packet. The enc28j60_send_packet function uses a workqueue that invokes enc28j60_hw_tx(). In between this function is called, the worker from the interrupt handler will enter the path for error handler because of the TXERIF flag, causing to invoke enc28j60_tx_clear() again and releasing the packet scheduled for transmission, causing a kernel crash with due a NULL pointer. These crashes due a NULL pointer were observed under stress conditions of the device. A BUG_ON() sequence was used to validate the issue was fixed, and has been running without problems for 2 years now. Signed-off-by: Diego Dompe <> Acked-by: Sergio Valverde <> Signed-off-by: David S.

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.")

git:// Pull libnvdimm fixes from Dan Williams: "1/ Two regression fixes since v4.6: one for the byte order of a sysfs attribute (bz121161) and another for QEMU 2.6's NVDIMM _DSM (ACPI Device Specific Method) implementation that gets tripped up by new auto-probing behavior in the NFIT driver. 2/ A fix tagged for -stable that stops the kernel from clobbering/ignoring changes to the configuration of a 'pfn' instance ("struct page" driver). For example changing the alignment from 2M to 1G may silently revert to 2M if that value is currently stored on media. 3/ A fix from Eric for an xfstests failure in dax. It is not currently tagged for -stable since it requires an 8-exabyte file system to trigger, and there appear to be no user visible side effects" * 'libnvdimm-fixes' of git:// nfit: fix format interface code byte order dax: fix offset overflow in dax_io acpi, nfit: fix acpi_check_dsm() vs zero functions implemented libnvdimm, pfn, dax: fix initialization vs autodetect for mode + alignment
2016-07-01tipc: fix nl compat regression for link statisticsRichard Alpe1-1/+1
Fix incorrect use of nla_strlcpy() where the first NLA_HDRLEN bytes of the link name where left out. Making the output of tipc-config -ls look something like: Link statistics: dcast-link 1:data0-1.1.2:data0 1:data0-1.1.3:data0 Also, for the record, the patch that introduce this regression claims "Sending the whole object out can cause a leak". Which isn't very likely as this is a compat layer, where the data we are parsing is generated by us and we know the string to be NULL terminated. But you can of course never be to secure.

2016-07-01macsec: set actual real device for xmit when !protect_framesDaniel Borkmann1-0/+1
Avoid recursions of dev_queue_xmit() to the wrong net device when frames are unprotected, since at that time skb->dev still points to our own macsec dev and unlike macsec_encrypt_finish() dev pointer doesn't get updated to real underlying device.

2016-07-01net_sched: fix mirrored packets checksumWANG Cong3-19/+20
Similar to commit 9b368814b336 ("net: fix bridge multicast packet checksum validation") we need to fixup the checksum for CHECKSUM_COMPLETE when pushing skb on RX path. Otherwise we get similar splats. Cc: Jamal Hadi Salim <> Cc: Tom Herbert <> Signed-off-by: Cong Wang <> Acked-by: Jamal Hadi Salim <> Signed-off-by: David S. Miller <>
2016-07-01packet: Use symmetric hash for PACKET_FANOUT_HASH.David S. Miller3-1/+45
People who use PACKET_FANOUT_HASH want a symmetric hash, meaning that they want packets going in both directions on a flow to hash to the same bucket. The core kernel SKB hash became non-symmetric when the ipv6 flow label and other entities were incorporated into the standard flow hash order to increase entropy. But there are no users of PACKET_FANOUT_HASH who want an assymetric hash, they all want a symmetric one. Therefore, use the flow dissector to compute a flat symmetric hash over only the protocol, addresses and ports. This hash does not get installed into and override the normal skb hash, so this change has no effect whatsoever on the rest of the stack.
