2018-09-18ipv6: fix memory leak on dst->_metricsWei Wang
When dst->_metrics and f6i->fib6_metrics share the same memory, both take reference count on the dst_metrics structure. However, when dst is destroyed, ip6_dst_destroy() only invokes dst_destroy_metrics_generic() which does not take care of READONLY metrics and does not release refcnt. This causes memory leak. Similar to ipv4 logic, the fix is to properly release refcnt and free the memory space pointed by dst->_metrics if refcnt becomes 0.

2018-09-18net/smc: fix non-blocking connect problemUrsula Braun
In state SMC_INIT smc_poll() delegates polling to the internal CLC socket. This means, once the connect worker has finished its kernel_connect() step, the poll wake-up may occur. This is not intended. The wake-up should occur from the wake up call in smc_connect_work() after __smc_connect() has finished. Thus in state SMC_INIT this patch now calls sock_poll_wait() on the main SMC socket. Signed-off-by: Ursula Braun <ubraun@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-18ravb: do not write 1 to reserved bitsKazuya Mizuguchi
EtherAVB hardware requires 0 to be written to status register bits in order to clear them, however, care must be taken not to: 1. Clear other bits, by writing zero to them 2. Write one to reserved bits This patch corrects the ravb driver with respect to the second point above. This is done by defining reserved bit masks for the affected registers and, after auditing the code, ensure all sites that may write a one to a reserved bit use are suitably masked.

2018-09-18net: emac: fix fixed-link setup for the RTL8363SB switchChristian Lamparter
On the Netgear WNDAP620, the emac ethernet isn't receiving nor xmitting any frames from/to the RTL8363SB (identifies itself as a RTL8367RB). This is caused by the emac hardware not knowing the forced link parameters for speed, duplex, pause, etc. This begs the question, how this was working on the original driver code, when it was necessary to set the phy_address and phy_map to 0xffffffff. But I guess without access to the old PPC405/440/460 hardware, it's not possible to know. Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-18NFC: Fix the number of pipesSuren Baghdasaryan
According to ETSI TS 102 622 specification chapter 4.4 pipe identifier is 7 bits long which allows for 128 unique pipe IDs. Because NFC_HCI_MAX_PIPES is used as the number of pipes supported and not as the max pipe ID, its value should be 128 instead of 127. nfc_hci_recv_from_llc extracts pipe ID from packet header using NFC_HCI_FRAGMENT(0x7F) mask which allows for pipe ID value of 127. Same happens when NCI_HCP_MSG_GET_PIPE() is being used. With pipes array having only 127 elements and pipe ID of 127 the OOB memory access will result.

2018-09-18NFC: Fix possible memory corruption when handling SHDLC I-Frame commandsSuren Baghdasaryan
When handling SHDLC I-Frame commands "pipe" field used for indexing into an array should be checked before usage. If left unchecked it might access memory outside of the array of size NFC_HCI_MAX_PIPES(127). Malformed NFC HCI frames could be injected by a malicious NFC device communicating with the device being attacked (remote attack vector), or even by an attacker with physical access to the I2C bus such that they could influence the data transfers on that bus (local attack vector). skb->data is controlled by the attacker and has only been sanitized in the most trivial ways (CRC check), therefore we can consider the create_info struct and all of its members to tainted. 'create_info->pipe' with max value of 255 (uint8) is used to take an offset of the hdev->pipes array of 127 elements which can lead to OOB write.
