2010-07-19bridge: Partially disable netpoll supportHerbert Xu2-31/+1
The new netpoll code in bridging contains use-after-free bugs that are non-trivial to fix. This patch fixes this by removing the code that uses skbs after they're freed. As a consequence, this means that we can no longer call bridge from the netpoll path, so this patch also removes the controller function in order to disable netpoll.

2010-07-19tcp: fix crash in tcp_xmit_retransmit_queueIlpo Järvinen1-0/+3
It can happen that there are no packets in queue while calling tcp_xmit_retransmit_queue(). tcp_write_queue_head() then returns NULL and that gets deref'ed to get sacked into a local var. There is no work to do if no packets are outstanding so we just exit early. This oops was introduced by 08ebd1721ab8fd (tcp: remove tp->lost_out guard to make joining diff nicer).

2010-07-19net: 64bit stats for netdev_queueEric Dumazet1-1/+3
Since struct netdev_queue tx_bytes/tx_packets/tx_dropped are already protected by _xmit_lock, its easy to convert these fields to u64 instead of unsigned long. This completes 64bit stats for devices using them (vlan, macvlan, ...) Strictly, we could avoid the locking in dev_txq_stats_fold() on 64bit arches, but its slow path and we prefer keep it simple.

2010-07-18net: support time stamping in phy devices.Richard Cochran5-1/+144
This patch adds a new networking option to allow hardware time stamps from PHY devices. When enabled, likely candidates among incoming and outgoing network packets are offered to the PHY driver for possible time stamping. When accepted by the PHY driver, incoming packets are deferred for later delivery by the driver. The patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl and callbacks for transmit and receive time stamping. Drivers may optionally implement these functions.

2010-07-18net: preserve ifreq parameter when calling generic phy_mii_ioctl().Richard Cochran1-2/+1
The phy_mii_ioctl() function unnecessarily throws away the original ifreq. We need access to the ifreq in order to support PHYs that can perform hardware time stamping. Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl(). This is unnecessary since phylib will check the command in any case.

2010-07-18vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)Pedro Garcia3-49/+86
- Without the 8021q module loaded in the kernel, all 802.1p packets (VLAN 0 but QoS tagging) are silently discarded (as expected, as the protocol is not loaded). - Without this patch in 8021q module, these packets are forwarded to the module, but they are discarded also if VLAN 0 is not configured, which should not be the default behaviour, as VLAN 0 is not really a VLANed packet but a 802.1p packet. Defining VLAN 0 makes it almost impossible to communicate with mixed 802.1p and non 802.1p devices on the same network due to arp table issues. - Changed logic to skip vlan specific code in vlan_skb_recv if VLAN is 0 and we have not defined a VLAN with ID 0, but we accept the packet with the encapsulated proto and pass it later to netif_rx. - In the vlan device event handler, added some logic to add VLAN 0 to HW filter in devices that support it (this prevented any traffic in VLAN 0 to reach the stack in e1000e with HW filter under 2.6.35, and probably also with other HW filtered cards, so we fix it here). - In the vlan unregister logic, prevent the elimination of VLAN 0 in devices with HW filter. - The default behaviour is to ignore the VLAN 0 tagging and accept the packet as if it was not tagged, but we can still define a VLAN 0 if desired (so it is backwards compatible).

2010-07-18IPv6: fix CoA check in RH2 input handler (mip6_rthdr_input())Arnaud Ebalard1-1/+2
The input handler for Type 2 Routing Header (mip6_rthdr_input()) checks if the CoA in the packet matches the CoA in the XFRM state. Current check is buggy: it compares the adddress in the Type 2 Routing Header, i.e. the HoA, against the expected CoA in the state. The comparison should be made against the address in the destination field of the IPv6 header. The bug remained unnoticed because the main (and possibly only current) user of the code (UMIP MIPv6 Daemon) initializes the XFRM state with the unspecified address, i.e. explicitly allows everything.

This adds a `CHECKSUM' target, which can be used in the iptables mangle table. You can use this target to compute and fill in the checksum in a packet that lacks a checksum. This is particularly useful, if you need to work around old applications such as dhcp clients, that do not work well with checksum offloads, but don't want to disable checksum offload in your device. The problem happens in the field with virtualized applications.

This patch adds the missing bits to support the recovery of TCP flows without disabling window tracking (aka be_liberal). To ensure a successful recovery, we have to inject the window scale factor via ctnetlink. This patch has been tested with a development snapshot of conntrackd and the new clause `TCPWindowTracking' that allows to perform strict TCP window tracking recovery across fail-overs. With this patch, we don't update the receiver's window until it's not initiated. We require this to perform a successful recovery.

2010-07-14net: fix problem in reading sock TX queueTom Herbert1-4/+3
Fix problem in reading the tx_queue recorded in a socket. In dev_pick_tx, the TX queue is read by doing a check with sk_tx_queue_recorded on the socket, followed by a sk_tx_queue_get. The problem is that there is not mutual exclusion across these calls in the socket so it it is possible that the queue in the sock can be invalidated after sk_tx_queue_recorded is called so that sk_tx_queue get returns -1, which sets 65535 in queue_index and thus dev_pick_tx returns 65536 which is a bogus queue and can cause crash in dev_queue_xmit. We fix this by only calling sk_tx_queue_get which does the proper checks. The interface is that sk_tx_queue_get returns the TX queue if the sock argument is non-NULL and TX queue is recorded, else it returns -1. sk_tx_queue_recorded is no longer used so it can be completely removed.

When configuring DMVPN (GRE + openNHRP) and a GRE remote address is configured a kernel Oops is observed. The obserseved Oops is caused by a NULL header_ops pointer (neigh->dev->header_ops) in neigh_update_hhs() when void (*update)(struct hh_cache*, const struct net_device*, const unsigned char *) = neigh->dev->header_ops->cache_update; is executed.

The reset_policy() does: memset(d->tcfd_defdata, 0, SIMP_MAX_DATA); strlcpy(d->tcfd_defdata, defdata, SIMP_MAX_DATA); In the original code, the size of d->tcfd_defdata wasn't fixed and if strlen(defdata) was less than 31, reset_policy() would cause memory corruption. Please Note: The original alloc_defdata() assumes defdata is 32 characters and a NUL terminator while reset_policy() assumes defdata is 31 characters and a NUL. This patch updates alloc_defdata() to match reset_policy() (ie a shorter string). I'm not very familiar with this code so please review carefully.

2010-07-14net: skb_tx_hash() fix relative to skb_orphan_try()Eric Dumazet1-3/+10
commit fc6055a5ba31e2 (net: Introduce skb_orphan_try()) added early orphaning of skbs. This unfortunately added a performance regression in skb_tx_hash() in case of stacked devices (bonding, vlans, ...) Since skb->sk is now NULL, we cannot access sk->sk_hash anymore to spread tx packets to multiple NIC queues on multiqueue devices. skb_tx_hash() in this case only uses skb->protocol, same value for all flows. skb_orphan_try() can copy sk->sk_hash into skb->rxhash and skb_tx_hash() can use this saved sk_hash value to compute its internal hash value.

2010-07-12net: autoconvert trivial BKL users to private mutexArnd Bergmann2-6/+8
All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <[email protected]> Cc: "David S.

In commit be1f3c2c027cc5ad735df6a45a542ed1db7ec48b "net: Enable 64-bit net device statistics on 32-bit architectures" I redefined struct net_device_stats so that it could be used in a union with struct rtnl_link_stats64, avoiding the need for explicit copying or conversion between the two. However, this is unsafe because there is no locking required and no lock consistently held around calls to dev_get_stats() and use of the statistics structure it returns. In commit 28172739f0a276eb8d6ca917b3974c2edb036da3 "net: fix 64 bit counters on 32 bit arches" Eric Dumazet dealt with that problem by requiring callers of dev_get_stats() to provide storage for the result. This means that the net_device::stats64 field and the padding in struct net_device_stats are now redundant, so remove them. Update the comment on net_device_ops::ndo_get_stats64 to reflect its new usage. Change dev_txq_stats_fold() to use struct rtnl_link_stats64, since that is what all its callers are really using and it is no longer going to be compatible with struct net_device_stats.
