2010-07-20drop_monitor: convert some kfree_skb call sites to consume_skbNeil Horman2-5/+6
Convert a few calls from kfree_skb to consume_skb Noticed while I was working on dropwatch that I was detecting lots of internal skb drops in several places. While some are legitimate, several were not, freeing skbs that were at the end of their life, rather than being discarded due to an error. This patch converts those calls sites from using kfree_skb to consume_skb, which quiets the in-kernel drop_monitor code from detecting them as drops.

2010-07-20drop_monitor: Add error code to detect duplicate state changesNeil Horman1-2/+8
Patch to add -EAGAIN error to dropwatch netlink message handling code. -EAGAIN will be returned anytime userspace attempts to transition the state of the drop monitor service to a state that its already in. That allows user space to detect this condition, so it doesn't wait for a success ACK that will never arrive.

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).

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.

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 <arnd@arndb.de> Cc: "David S.

2010-07-09net: Get rid of rtnl_link_stats64 / net_device_stats unionBen Hutchings2-6/+27
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. Eric Dumazet suggested the separate function for the structure conversion.

There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

Reducing real_num_queues needs to flush the qdisc otherwise skbs with queue_mappings greater then real_num_tx_queues can be sent to the underlying driver. The flow for this is, dev_queue_xmit() dev_pick_tx() skb_tx_hash() => hash using real_num_tx_queues skb_set_queue_mapping() ... qdisc_enqueue_root() => enqueue skb on txq from hash ... dev->real_num_tx_queues -= n ... sch_direct_xmit() dev_hard_start_xmit() ndo_start_xmit(skb,dev) => skb queue set with old hash skbs are enqueued on the qdisc with skb->queue_mapping set 0 < queue_mappings < real_num_tx_queues. When the driver decreases real_num_tx_queues skb's may be dequeued from the qdisc with a queue_mapping greater then real_num_tx_queues. This fixes a case in ixgbe where this was occurring with DCB and FCoE. Because the driver is using queue_mapping to map skbs to tx descriptor rings we can potentially map skbs to rings that no longer exist.
