In the current driver, the MTU is set to the maximum value capable for the backing device. This decision turned out to be a mistake as it led to confusion among users. The expected initial MTU value used for other IBM vNIC capable operating systems is 1500, with the maximum value (9000) reserved for when Jumbo frames are enabled. This patch sets the MTU to the default value for a net device. It also corrects a discrepancy between MTU values received from firmware, which includes the ethernet header length, and net device MTU values. Finally, it removes redundant min/max MTU assignments after device initialization. Signed-off-by: NThomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Jonathan T. Leighton says: ==================== IPv4-mapped on wire, :: dst address issue Under some circumstances IPv6 datagrams are sent with IPv4-mapped IPv6 addresses as the source. Given an IPv6 socket bound to an IPv4-mapped IPv6 address, and an IPv6 destination address, both TCP and UDP will will send packets using the IPv4-mapped IPv6 address as the source. Per RFC 6890 (Table 20), IPv4-mapped IPv6 source addresses are not allowed in an IP datagram. The problem can be observed by attempting to connect() either a TCP or UDP socket, or by using sendmsg() with a UDP socket. The patch is intended to correct this issue for all socket types. linux follows the BSD convention that an IPv6 destination address specified as in6addr_any is converted to the loopback address. Currently, neither TCP nor UDP consider the possibility that the source address is an IPv4-mapped IPv6 address, and assume that the appropriate loopback address is ::1. The patch adds a check on whether or not the source address is an IPv4-mapped IPv6 address and then sets the destination address to either ::ffff:127.0.0.1 or ::1, as appropriate. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds a check on the type of the source address for the case where the destination address is in6addr_any. If the source is an IPv4-mapped IPv6 source address, the destination is changed to ::ffff:127.0.0.1, and otherwise the destination is changed to ::1. This is done in three locations to handle UDP calls to either connect() or sendmsg() and TCP calls to connect(). Note that udpv6_sendmsg() delays handling an in6addr_any destination until very late, so the patch only needs to handle the case where the source is an IPv4-mapped IPv6 address.

Herbert Xu says: ==================== rhashtable: Handle table allocation failure during insertion v2 - Added Ack to patch 2. Fixed RCU annotation in code path executed by rehasher by using rht_dereference_bucket. v1 - This series tackles the problem of table allocation failures during insertion. The issue is that we cannot vmalloc during insertion. This series deals with this by introducing nested tables. The first two patches removes manual hash table walks which cannot work on a nested table. The final patch introduces nested tables. I've tested this with test_rhashtable and it appears to work. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Herbert Xu 提交于
This patch adds code that handles GFP_ATOMIC kmalloc failure on insertion. As we cannot use vmalloc, we solve it by making our hash table nested. That is, we allocate single pages at each level and reach our desired table size by nesting them. When a nested table is created, only a single page is allocated at the top-level. Lower levels are allocated on demand during insertion. Therefore for each insertion to succeed, only two (non-consecutive) pages are needed. After a nested table is created, a rehash will be scheduled in order to switch to a vmalloced table as soon as possible. Also, the rehash code will never rehash into a nested table. If we detect a nested table during a rehash, the rehash will be aborted and a new rehash will be scheduled. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

There are two problems with the function tipc_sk_reinit. Firstly it's doing a manual walk over an rhashtable. This is broken as an rhashtable can be resized and if you manually walk over it during a resize then you may miss entries. Secondly it's missing memory barriers as previously the code used spinlocks which provide the barriers implicitly. This patch fixes both problems.

When sending ARP requests over AX.25 links the hwaddress in the neighbour cache are not getting initialized. For such an incomplete arp entry ax2asc2 will generate an empty string resulting in /proc/net/arp output like the following: $ cat /proc/net/arp IP address HW type Flags HW address Mask Device 192.168.122.1 0x1 0x2 52:54:00:00:5d:5f * ens3 172.20.1.99 0x3 0x0 * bpq0 The missing field will confuse the procfs parsing of arp(8) resulting in incorrect output for the device such as the following: $ arp Address HWtype HWaddress Flags Mask Iface gateway ether 52:54:00:00:5d:5f C ens3 172.20.1.99 (incomplete) ens3 This changes the content of /proc/net/arp to: $ cat /proc/net/arp IP address HW type Flags HW address Mask Device 172.20.1.99 0x3 0x0 * * bpq0 192.168.122.1 0x1 0x2 52:54:00:00:5d:5f * ens3 To do so it change ax2asc to put the string "*" in buf for a NULL address argument.

If BPF_F_ALLOW_OVERRIDE flag is used in BPF_PROG_ATTACH command to the given cgroup the descendent cgroup will be able to override effective bpf program that was inherited from this cgroup. By default it's not passed, therefore override is disallowed. Examples: 1. prog X attached to /A with default prog Y fails to attach to /A/B and /A/B/C Everything under /A runs prog X 2. prog X attached to /A with allow_override. prog Y fails to attach to /A/B with default (non-override) prog M attached to /A/B with allow_override. Everything under /A/B runs prog M only. 3. prog X attached to /A with allow_override. prog Y fails to attach to /A with default. The user has to detach first to switch the mode. In the future this behavior may be extended with a chain of non-overridable programs. Also fix the bug where detach from cgroup where nothing is attached was not throwing error.

In function igmpv3/mld_add_delrec() we allocate pmc and put it in idev->mc_tomb, so we should free it when we don't need it in del_delrec(). But I removed kfree(pmc) incorrectly in latest two patches. Now fix it. Fixes: 24803f38 ("igmp: do not remove igmp souce list info when ...")

This fixes a crash when running out of grant refs when creating many queues across many netdevs. * If creating queues fails (i.e. there are no grant refs available), call xenbus_dev_fatal() to ensure that the xenbus device is set to the closed state. * If no queues are created, don't call xennet_disconnect_backend as netdev->real_num_tx_queues will not have been set correctly. * If setup_netfront() fails, ensure that all the queues created are cleaned up, not just those that have been set up. * If any queues were set up and an error occurs, call xennet_destroy_queues() to clean up the napi context. * If any fatal error occurs, unregister and destroy the netdev to avoid leaving around a half setup network device.
