ax88179_tx_fixup() has quite complex code trying to push 8 bytes of control data (len/mss), but fails to do it properly for TCP packets, incurring an extra copy and point of memory allocation failure. Lets use the simple and approved way. dev->needed_headroom being 8, all frames should have 8 bytes of headroom, so the extra copy should be unlikely anyway. This patch should improve performance for TCP xmits.

This change brings the suppressor attribute names into line; it also changes the data types to provide a more consistent interface. While -1 indicates that the suppressor is not enabled, values >= 0 for suppress_prefixlen or suppress_ifgroup reject routing decisions violating the constraint. This changes the previously presented behaviour of suppress_prefixlen, where a prefix length _less_ than the attribute value was rejected. After this change, a prefix length less than *or* equal to the value is considered a violation of the rule constraint. It also changes the default values for default and newly added rules (disabling any suppression for those). Signed-off-by: NStefan Tomanek <stefan.tomanek@wertarbyte.de> Signed-off-by: NDavid S.

由 Paul Moore 提交于
NetLabel has the ability to selectively assign network security labels to outbound traffic based on either the LSM's "domain" (different for each LSM), the network destination, or a combination of both. Depending on the type of traffic, local or forwarded, and the type of traffic selector, domain or address based, different hooks are used to label the traffic; the goal being minimal overhead. Unfortunately, there is a bug such that a system using NetLabel domain based traffic selectors does not correctly label outbound local traffic that is not assigned to a socket. The issue is that in these cases the associated NetLabel hook only looks at the address based selectors and not the domain based selectors. This patch corrects this by checking both the domain and address based selectors so that the correct labeling is applied, regardless of the configuration type. In order to acomplish this fix, this patch also simplifies some of the NetLabel domainhash structures to use a more common outbound traffic mapping type: struct netlbl_dommap_def. This simplifies some of the code in this patch and paves the way for further simplifications in the future. Signed-off-by: NPaul Moore <pmoore@redhat.com> Signed-off-by: NDavid S.

Veaceslav Falico says: ==================== Recent patches revealed an old bug, which was there for quite awhile. It's related to vlan on top of bonding and ndo_neigh_setup(). When vlan device is initiated, it calls its real_dev->ndo_neigh_setup(), and in case of bonding - it will modify neigh_parms->neigh_setup to point to bond_neigh_init, while neigh_parms are of vlan's dev. This way, when neigh_parms->neigh_setup() of vlan's dev is called, the bonding function will be called, which expects the dev to be struct bonding, but will receive a vlan dev. It was hidden before because of bond->first_slave usage. Now, with Nikolay's conversion to list/RCU, first_slave is gone and we hit a null pointer dereference when working with lists/slave. First patch moves ndo_neigh_setup() in neigh_parms_alloc() to the bottom, so that the ->dev will be available to the caller. It doesn't really change anything, however is needed for the second patch. Second patch makes bond_neigh_setup() (bond->ndo_neigh_setup()) check if the neigh_parms are really from a bonding dev, and only modify the neigh_setup in this case. ==================== Signed-off-by: NDavid S.

It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.

By using sizeof(_hdr), net/ipv6/raw.c:icmpv6_filter implicitly assumes that any valid ICMPv6 message is at least eight bytes long, i.e., that the message body is at least four bytes. The DIS message of RPL (RFC 6550 section 6.2, from the 6LoWPAN world), has a minimum length of only six bytes, and is thus blocked by icmpv6_filter. RFC 4443 seems to allow even a zero-sized body, making the minimum allowable message size four bytes. Signed-off-by: NWerner Almesberger <werner@almesberger.net> Signed-off-by: NDavid S.
