2011-01-14r8169: keep firmware in memory.françois romieu
The firmware agent is not available during resume. Loading the firmware during open() (see eee3a96c6368f47df8df5bd4ed1843600652b337) is not enough. close() is run during resume through rtl8169_reset_task(), whence the mildly natural release of firmware in the driver removal method instead. It will help with http://bugs.debian.org/609538. It will not avoid the 60 seconds delay when: - there is no firmware - the driver is loaded and the device is not up before a suspend/resume Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Tested-by: Jarek Kamiński <jarek@vilo.eu.org> Cc: Hayes <hayeswang@realtek.com> Cc: Ben Hutchings <benh@debian.org> Signed-off-by: David S.

Therefore, define two separate ethtool_ops structures for WAN and non-WAN ports; simplify and rename the WAN-only functions. This is completely untested as I don't have an ARM build environment.

2011-01-14USB CDC NCM: Don't deref NULL in cdc_ncm_rx_fixup() and don't use ↵Jesper Juhl
uninitialized variable. skb_clone() dynamically allocates memory and may fail. If it does it returns NULL. This means we'll dereference a NULL pointer in drivers/net/usb/cdc_ncm.c::cdc_ncm_rx_fixup(). As far as I can tell, the proper way to deal with this is simply to goto the error label. Furthermore gcc complains that 'skb' may be used uninitialized: drivers/net/usb/cdc_ncm.c: In function ‘cdc_ncm_rx_fixup’: drivers/net/usb/cdc_ncm.c:922:18: warning: ‘skb’ may be used uninitialized in this function and I believe it is right. On the line where we pr_debug("invalid frame detected (ignored)" ... we are using the local variable 'skb' but nothing has ever been assigned to that variable yet. I believe the correct fix for that is to use 'skb_in' instead. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-14net: remove dev_txq_stats_fold()Eric Dumazet
After recent changes, (percpu stats on vlan/tunnels...), we dont need anymore per struct netdev_queue tx_bytes/tx_packets/tx_dropped counters. Only remaining users are ixgbe, sch_teql, gianfar & macvlan : 1) ixgbe can be converted to use existing tx_ring counters. 2) macvlan incremented txq->tx_dropped, it can use the dev->stats.tx_dropped counter. 3) sch_teql : almost revert ab35cd4b8f42 (Use net_device internal stats) Now we have ndo_get_stats64(), use it, even for "unsigned long" fields (No need to bring back a struct net_device_stats) 4) gianfar adds a stats structure per tx queue to hold tx_bytes/tx_packets This removes a lockdep warning (and possible lockup) in rndis gadget, calling dev_get_stats() from hard IRQ context.

2011-01-13netfilter: ctnetlink: fix loop in ctnetlink_get_conntrack()Pablo Neira Ayuso
This patch fixes a loop in ctnetlink_get_conntrack() that can be triggered if you use the same socket to receive events and to perform a GET operation. Under heavy load, netlink_unicast() may return -EAGAIN, this error code is reserved in nfnetlink for the module load-on-demand. Instead, we return -ENOBUFS which is the appropriate error code that has to be propagated to user-space.

broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f99025f13b32502fe5dedf223c20d7283826 (bridge: add proper RCU annotation to should_route_hook) introduced a typedef, and then changed this to: br_should_route_hook_t *rhook; [..] rhook = rcu_dereference(br_should_route_hook); if (*rhook(skb)) problem is that "br_should_route_hook" contains the address of the function, so calling *rhook() results in kernel panic.

2011-01-11netfilter: fix race in conntrack between dump_table and destroyStephen Hemminger
The netlink interface to dump the connection tracking table has a race when entries are deleted at the same time. A customer reported a crash and the backtrace showed thatctnetlink_dump_table was running while a conntrack entry was being destroyed. (see https://bugzilla.vyatta.com/show_bug.cgi?id=6402). According to RCU documentation, when using hlist_nulls the reader must handle the case of seeing a deleted entry and not proceed further down the linked list. The old code would continue which caused the scan to walk into the free list. This patch uses locking (rather than RCU) for this operation which is guaranteed safe, and no longer requires getting reference while doing dump operation.

2011-01-11tcp: disallow bind() to reuse addr/portEric Dumazet
inet_csk_bind_conflict() logic currently disallows a bind() if it finds a friend socket (a socket bound on same address/port) satisfying a set of conditions : 1) Current (to be bound) socket doesnt have sk_reuse set OR 2) other socket doesnt have sk_reuse set OR 3) other socket is in LISTEN state We should add the CLOSE state in the 3) condition, in order to avoid two REUSEADDR sockets in CLOSE state with same local address/port, since this can deny further operations. Note : a prior patch tried to address the problem in a different (and buggy) way. (commit fda48a0d7a8412ced tcp: bind() fix when many ports are bound).
