d9aee59 | Yuval Mintz | 15 January 2014, 10:05:30 UTC | bnx2x: Don't release PCI bars on shutdown The bnx2x driver in its pci shutdown() callback releases its pci bars (in the same manner it does during its pci remove() callback). During a system reboot while VFs are enabled, its possible for the VF's remove to be called (as a result of pci_disable_sriov()) after its shutdown callback has already finished running; This will cause a paging request fault as the VF tries to access the pci bar which it has previously released, crashing the system. This patch further differentiates the shutdown and remove callbacks, preventing the pci release procedures from being called during shutdown.

95f4a45 | Hannes Frederic Sowa | 13 January 2014, 01:45:22 UTC | net: avoid reference counter overflows on fib_rules in multicast forwarding Bob Falken reported that after 4G packets, multicast forwarding stopped working. This was because of a rule reference counter overflow which freed the rule as soon as the overflow happend. This patch solves this by adding the FIB_LOOKUP_NOREF flag to fib_rules_lookup calls. This is safe even from non-rcu locked sections as in this case the flag only implies not taking a reference to the rule, which we don't need at all. Rules only hold references to the namespace, which are guaranteed to be available during the call of the non-rcu protected function reg_vif_xmit because of the interface reference which itself holds a reference to the net namespace.

This brings the inet_diag state-matching code in line with the field it uses to populate idiag_state. This is also analogous to the info exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state and get_timewait4_sock() exports tw->tw_substate. Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi state time-wait" would also return sockets in state TCP_FIN_WAIT2.

f663dd9 | Jason Wang | 10 January 2014, 08:18:26 UTC | net: core: explicitly select a txq before doing l2 forwarding Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

07edd74 | Hannes Frederic Sowa | 08 January 2014, 14:43:22 UTC | ipv6: add link-local, sit and loopback address with INFINITY_LIFE_TIME In the past the IFA_PERMANENT flag indicated, that the valid and preferred lifetime where ignored. Since change fad8da3e085ddf ("ipv6 addrconf: fix preferred lifetime state-changing behavior while valid_lft is infinity") we honour at least the preferred lifetime on those addresses. As such the valid lifetime gets recalculated and updated to 0. If loopback address is added manually this problem does not occur. Also if NetworkManager manages IPv6, those addresses will get added via inet6_rtm_newaddr and thus will have a correct lifetime, too.

f8dae00 | John David Anglin | 06 January 2014, 02:25:00 UTC | parisc: Ensure full cache coherency for kmap/kunmap Helge Deller noted a few weeks ago problems with the AIO support on parisc. This change is the result of numerous iterations on how best to deal with this problem. The solution adopted here is to provide full cache coherency in a uniform manner on all parisc systems. This involves calling flush_dcache_page() on kmap operations and flush_kernel_dcache_page() on kunmap operations. As a result, the copy_user_page() and clear_user_page() functions can be removed and the overall code is simpler. The change ensures that both userspace and kernel aliases to a mapped page are invalidated and flushed. This is necessary for the correct operation of PA8800 and PA8900 based systems which do not support inequivalent aliases. With this change, I have observed no cache related issues on c8000 and rp3440. It is now possible for example to do kernel builds with "-j64" on four way systems. On systems using XFS file systems, the patch recently posted by Mikulas Patocka to "fix crash using XFS on loopback" is needed to avoid a hang caused by an uninitialized lock passed to flush_dcache_page() in the page struct.

However it used the type u8 for the div field, causing divisors larger than 255 to be masked and the resultant clock rate to be too high. E.g. in my case an 11bit divider was supposed to divide 24.576 MHz down to 32.768KHz. The divisor was correctly calculated as 750 (0x2ee). This was masked to 238 (0xee) resulting in a frequency of 103.26KHz.

After the fragment chain with the complete message has been successfully delivered to the receiving socket, it is released.

Note that everyone can't now just relax because "Jani will do all the bug scrubbing" - au contraire expect more nagging and poking now that we have more bandwidth. Longer-term the plan is to share more of the maintainer duties, but we need to fix up the infrastructure a bit first (like moving the git repo to a common location).

fe0d692 | Curt Brune | 06 January 2014, 19:00:32 UTC | bridge: use spin_lock_bh() in br_multicast_set_hash_max br_multicast_set_hash_max() is called from process context in net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function. br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock), which can deadlock the CPU if a softirq that also tries to take the same lock interrupts br_multicast_set_hash_max() while the lock is held . This can happen quite easily when any of the bridge multicast timers expire, which try to take the same lock. The fix here is to use spin_lock_bh(), preventing other softirqs from executing on this CPU. Steps to reproduce: 1. Create a bridge with several interfaces (I used 4). 2. Set the "multicast query interval" to a low number, like 2. 3. Enable the bridge as a multicast querier. 4. Repeatedly set the bridge hash_max parameter via sysfs. # brctl addbr br0 # brctl addif br0 eth1 eth2 eth3 eth4 # brctl setmcqi br0 2 # brctl setmcquerier br0 1 # while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Signed-off-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: David S.

e5e97ee | Dan Williams | 06 January 2014, 16:07:29 UTC | hso: fix handling of modem port SERIAL_STATE notifications The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port. Signed-off-by: Dan Williams <dcbw@redhat.com> Tested-by: H.

It causes xfstests generic/006 and /013 to fail with an unexpected JBD2 failure and transaction abort that leaves the test file system in a read only state. Other xfstests run on bigalloc file systems are likely to fail as well. The cause is the accidental use of a cluster mask where a cluster offset was needed in ext4_ext_map_blocks().

2690d97 | Daniel Borkmann | 31 December 2013, 15:28:39 UTC | netfilter: nf_nat: fix access to uninitialized buffer in IRC NAT helper Commit 5901b6be885e attempted to introduce IPv6 support into IRC NAT helper. By doing so, the following code seemed to be removed by accident: ip = ntohl(exp->master->tuplehash[IP_CT_DIR_REPLY].tuple.dst.u3.ip); sprintf(buffer, "%u %u", ip, port); pr_debug("nf_nat_irc: inserting '%s' == %pI4, port %u\n", buffer, &ip, port); This leads to the fact that buffer[] was left uninitialized and contained some stack value. When we call nf_nat_mangle_tcp_packet(), we call strlen(buffer) on excatly this uninitialized buffer. If we are unlucky and the skb has enough tailroom, we overwrite resp. leak contents with values that sit on our stack into the packet and send that out to the receiver. Since the rather informal DCC spec [1] does not seem to specify IPv6 support right now, we log such occurences so that admins can act accordingly, and drop the packet. I've looked into XChat source, and IPv6 is not supported there: addresses are in u32 and print via %u format string. Therefore, restore old behaviour as in IPv4, use snprintf(). The IRC helper does not support IPv6 by now. By this, we can safely use strlen(buffer) in nf_nat_mangle_tcp_packet() and prevent a buffer overflow. Also simplify some code as we now have ct variable anyway.

940d9d3 | Thadeu Lima de Souza Cascardo | 23 December 2013, 17:34:29 UTC | cxgb4: allow large buffer size to have page size Since commit 52367a763d8046190754ab43743e42638564a2d1 ("cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support"), we have failures like this during cxgb4 probe: cxgb4 0000:01:00.4: bad SGE FL page buffer sizes [65536, 65536] cxgb4: probe of 0000:01:00.4 failed with error -22 This happens whenever software parameters are used, without a configuration file. That happens when the hardware was already initialized (after kexec, or after csiostor is loaded). It happens that these values are acceptable, rendering fl_pg_order equal to 0, which is the case of a hard init when the page size is equal or larger than 65536. Accepting fl_large_pg equal to fl_small_pg solves the issue, and shouldn't cause any trouble besides a possible performance reduction when smaller pages are used. And that can be fixed by a configuration file. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: David S.
