| * appletalk: Fix OOPS in atalk_release().David S. Miller2011-03-31
| | | | | | | | | | | | | | | | | | | | | | | | Commit 60d9f461a20ba59219fdcdc30cbf8e3a4ad3f625 ("appletalk: remove the BKL") added a dereference of "sk" before checking for NULL in atalk_release(). Guard the code block completely, rather than partially, with the NULL check. Reported-by: Dave Jones <davej@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * atm/solos-pci: Don't flap VCs when carrier state changesPhilip A. Prindeville2011-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't flap VCs when carrier state changes; higher-level protocols can detect loss of connectivity and act accordingly. This is more consistent with how other network interfaces work. We no longer use release_vccs() so we can delete it. release_vccs() was duplicated from net/atm/common.c; make the corresponding function exported, since other code duplicates it and could leverage it if it were public.

| * netdev: fix mtu check when TSO is enabledDaniel Lezcano2011-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case the device where is coming from the packet has TSO enabled, we should not check the mtu size value as this one could be bigger than the expected value. This is the case for the macvlan driver when the lower device has TSO enabled. The macvlan inherit this feature and forward the packets without fragmenting them. Then the packets go through dev_forward_skb and are dropped. This patch fix this by checking TSO is not enabled when we want to check the mtu size.

| * bridge: mcast snooping, fix length check of snooped MLDv1/2Linus Lüssing2011-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "len = ntohs(ip6h->payload_len)" does not include the length of the ipv6 header itself, which the rest of this function assumes, though. This leads to a length check less restrictive as it should be in the following line for one thing. For another, it very likely leads to an integer underrun when substracting the offset and therefore to a very high new value of 'len' due to its unsignedness. This will ultimately lead to the pskb_trim_rcsum() practically never being called, even in the cases where it should. Signed-off-by: Linus Lüssing <linus.luessing@web.de> Signed-off-by: David S.

| * net: gre: provide multicast mappings for ipv4 and ipv6Timo Teräs2011-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My commit 6d55cb91a0020ac0 (gre: fix hard header destination address checking) broke multicast. The reason is that ip_gre used to get ipgre_header() calls with zero destination if we have NOARP or multicast destination. Instead the actual target was decided at ipgre_tunnel_xmit() time based on per-protocol dissection. Instead of allowing the "abuse" of ->header() calls with invalid destination, this creates multicast mappings for ip_gre. This also fixes "ip neigh show nud noarp" to display the proper multicast mappings used by the gre device.

| | | | | | | | | | | | | | | | | | | | | | | | We should only clear r_osd if we are neither registered as a linger or a regular request. We may unregister as a linger while still registered as a regular request (e.g., in reset_osd). Incorrectly clearing r_osd there leads to a null pointer dereference in __send_request.

This fixes an oops easily triggered under UML by while true ; do mount ... ; umount ... ; done Also fix an outdated comment: the flush in ceph_destroy_client only flushes OSD connections out.

As far as i understand it, it should behave like when originating packets. Currently it will only timestamp the next free slot if: - there is space for *two* timestamps - some random data from the echoed packet taken as an IP is *not* a local IP This first is caused by an off-by-one error. 'soffset' points to the next free slot and so we only need to have 'soffset + 7 <= optlen'. The second bug is using sptr as the start of the option, when it really is set to 'skb_network_header(skb)'. I just use dptr instead which points to the timestamp option. Finally it would only timestamp for non-local IPs, which we shouldn't do. So instead we exclude all unicast destinations, similar to what we do in ip_options_compile().

Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure. Additionally, when parsing the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP facilities fields, a remote host can provide a length of less than 10, resulting in an underflow in a memcpy size, causing a kernel panic due to massive heap corruption. A length of greater than 20 results in a stack overflow of the callsign array. Abort facilities parsing on these invalid length values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Any operation that: 1) Brings up an interface 2) Adds an IP address to an interface 3) Deletes an IP address from an interface can potentially invalidate the nh_saddr value, requiring it to be recomputed. Perform the recomputation lazily using a generation ID. Reported-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S. Miller <davem@davemloft.net>

Instead, it consults a hash table of addresses configured to interfaces. This works identically to the old code in all except one case, and that is for loopback subnets. The old code would match the loopback device for any IP address that falls within a subnet configured to the loopback device. Handle this corner case by doing the FIB lookup. We could implement this via inet_addr_onlink() but: 1) Someone could configure many addresses to loopback and inet_addr_onlink() is a simple list traversal. 2) We know the old code works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current undo logic, cwnd is moderated after it was restored to the value prior entering fast-recovery. It was moderated first in tcp_try_undo_recovery then again in tcp_complete_cwr. Since the undo indicates recovery was false, these moderations are not necessary. If the undo is triggered when most of the outstanding data have been acknowledged, the (restored) cwnd is falsely pulled down to a small value. This patch removes these cwnd moderations if cwnd is undone a) during fast-recovery b) by receiving DSACKs past fast-recovery Signed-off-by: Yuchung Cheng <ycheng@google.com> Signed-off-by: David S.

| * | bridge: Fix possibly wrong MLD queries' ethernet source addressLinus Lüssing2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipv6_dev_get_saddr() is currently called with an uninitialized destination address. Although in tests it usually seemed to nevertheless always fetch the right source address, there seems to be a possible race condition. Therefore this commit changes this, first setting the destination address and only after that fetching the source address.

When in AP mode, hostapd uses it for kicking out inactive clients after a while. Without this patch, hostapd immediately deauthenticates a new client if it checks the inactivity time before the client sends its first data frame.

It will save some CPU cycles because we are sure the promoted secondary was first for the subnet and all next secondaries do not change their place.
