Updating the FIB tracepoint for the recent change to allow rules using the protocol and ports exposed a few places where the entries in the flow struct are not initialized. For __fib_validate_source add the call to fib4_rules_early_flow_dissect since it is invoked for the input path. For netfilter, add the memset on the flow struct to avoid future problems like this. In ip_route_input_slow need to set the fields if the skb dissection does not happen. Fixes: bfff4862 ("net: fib_rules: support for match on ip_proto, sport and dport") Signed-off-by:

After commit b196d88a ("tun: fix use after free for ptr_ring") we need clean up tx ring during release(). But unfortunately, it tries to do the cleanup blindly after socket were destroyed which will lead another use-after-free. Fix this by doing the cleanup before dropping the last reference of the socket in __tun_detach(). Reported-by:

Florian Fainelli says: ==================== net: dsa: bcm_sf2: CFP fixes This patch series fixes a number of usability issues with the SF2 Compact Field Processor code: - we would not be properly bound checking the location when we let the kernel automatically place rules with RX_CLS_LOC_ANY - when using IPv6 rules and user space specifies a location identifier we would be off by one in what the chain ID (within the Broadcom tag) indicates - it would be possible to delete one of the two slices of an IPv6 while leaving the other one programming leading to various problems ==================== Signed-off-by: -
Florian Fainelli authored
It was possible to delete only one half of an IPv6, which would leave the second half still programmed and possibly in use. Instead of checking for the unused bitmap, we need to check the unique bitmap, and refuse any deletion that does not match that criteria. We also need to move that check from bcm_sf2_cfp_rule_del_one() into its caller: bcm_sf2_cfp_rule_del() otherwise we would not be able to delete second halves anymore that would not pass the first test.

Florian Fainelli authored
We had several issues that would make the programming of IPv6 rules both inconsistent and error prone: - the chain ID that we would be asking the hardware to put in the packet's Broadcom tag would be off by one, it would return one of the two indexes, but not the one user-space specified - when an user specified a particular location to insert a CFP rule at, we would not be returning the same index, which would be confusing if nothing else - finally, like IPv4, it would be possible to overflow the last entry by re-programming it Fix this by swapping the usage of rule_index[0] and rule_index[1] where relevant in order to return a consistent and correct user-space experience.

When we let the kernel pick up a rule location with RX_CLS_LOC_ANY, we would be able to overwrite the last rules because of a number of issues. The IPv4 code path would not be checking that rule_index is within bounds, and it would also only be allowed to pick up rules from range 0..126 instead of the full 0..127 range. This would lead us to allow overwriting the last rule when we let the kernel pick-up the location. Fixes: 33061458 ("net: dsa: bcm_sf2: Move IPv4 CFP processing to specific functions") Signed-off-by:

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be used as reference clock for the MAC unit. The clock signal must meet the RGMII requirements to ensure the correct data transmission between the MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle requirement if the phy is configured as slave. For a complete describtion look at the errata sheets: DS80000691D or DS80000692D. The errata sheet recommends to force the phy into master mode whenever there is a 1000Base-T link-up as work around. Only set the "micrel,force-master" property if you use the phy reference clock provided by CLK125_NDO pin as MAC reference clock in your application. Attenation, this workaround is only usable if the link partner can be configured to slave mode for 1000Base-T. Signed-off-by:

It's possible to crash the kernel in several different ways by sending messages to the SMC_PNETID generic netlink family that are missing the expected attributes: - Missing SMC_PNETID_NAME => null pointer dereference when comparing names. - Missing SMC_PNETID_ETHNAME => null pointer dereference accessing smc_pnetentry::ndev. - Missing SMC_PNETID_IBNAME => null pointer dereference accessing smc_pnetentry::smcibdev. - Missing SMC_PNETID_IBPORT => out of bounds array access to smc_ib_device::pattr[-1].

We used to initialize ptr_ring during TUNSETIFF, this is because its size depends on the tx_queue_len of netdevice. And we try to clean it up when socket were detached from netdevice. A race were spotted when trying to do uninit during a read which will lead a use after free for pointer ring. Solving this by always initialize a zero size ptr_ring in open() and do resizing during TUNSETIFF, and then we can safely do cleanup during close(). With this, there's no need for the workaround that was introduced by commit 4df0bfc7 ("tun: fix a memory leak for tfile->tx_array").

Packet sockets allow construction of packets shorter than dev->hard_header_len to accommodate protocols with variable length link layer headers. These packets are padded to dev->hard_header_len, because some device drivers interpret that as a minimum packet size. packet_snd reserves dev->hard_header_len bytes on allocation. SOCK_DGRAM sockets call skb_push in dev_hard_header() to ensure that link layer headers are stored in the reserved range. SOCK_RAW sockets do the same in tpacket_snd, but not in packet_snd. Syzbot was able to send a zero byte packet to a device with massive 116B link layer header, causing padding to cross over into skb_shinfo. Fix this by writing from the start of the llheader reserved range also in the case of packet_snd/SOCK_RAW. Update skb_set_network_header to the new offset. This also corrects it for SOCK_DGRAM, where it incorrectly double counted reserve due to the skb_push in dev_hard_header.

Pull powerpc fixes from Michael Ellerman: "One fix for an actual regression, the change to the SYSCALL_DEFINE wrapper broke FTRACE_SYSCALLS for us due to a name mismatch. There's also another commit to the same code to make sure we match all our syscalls with various prefixes. And then just one minor build fix, and the removal of an unused variable that was removed and then snuck back in due to some rebasing. Thanks to: Naveen N. Rao" * tag 'powerpc-4.17-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/pseries: Fix CONFIG_NUMA=n build powerpc/trace/syscalls: Update syscall name matching logic to account for ppc_ prefix powerpc/trace/syscalls: Update syscall name matching logic powerpc/64: Remove unused paca->soft_enabled

Pull tracing fix from Steven Rostedt: "Working on some new updates to trace filtering, I noticed that the regex_match_front() test was updated to be limited to the size of the pattern instead of the full test string. But as the test string is not guaranteed to be nul terminated, it still needs to consider the size of the test string" * tag 'trace-v4.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Fix regex_match_front() to not over compare the test string

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-05-11 This series contains fixes to the ice, ixgbe and ixgbevf drivers. Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or not the hardware responds with an error in the ice driver. Emil adds a check for unsupported module during the reset routine for ixgbe. Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the correct return value (int). Colin Ian King fixes a potential resource leak in ixgbe, where we were not freeing ipsec in our cleanup path. ==================== Signed-off-by: -

David Howells says: ==================== rxrpc: Fixes Here are three fixes for AF_RXRPC and two tracepoints that were useful for finding them: (1) Fix missing start of expect-Rx-by timeout on initial packet transmission so that calls will time out if the peer doesn't respond. (2) Fix error reception on AF_INET6 sockets by using the correct family of sockopts on the UDP transport socket. (3) Fix setting the minimum security level on kernel calls so that they can be encrypted. (4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the transport socket. (5) Add a tracepoint to log UDP sendmsg failure so that we can find out if transmission failure occurred on the UDP socket. ==================== Signed-off-by:
