2007-07-31[NET] loopback: Panic if registration failsHerbert Xu
Because IPv4 and IPv6 both depend on the presence of the loopback device to function, failure in registration the loopback device should be fatal. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-31[NET]: Take dev_base_lock when moving device name hash list entryHerbert Xu
When we added name-based hashing the dev_base_lock was designated as the lock to take when changing the name hash list. Unfortunately, because it was a preexisting lock that just happened to be taken in the right spots we neglected to take it in dev_change_name. The race can affect calles of __dev_get_by_name that do so without taking the RTNL. They may end up walking down the wrong hash chain and end up missing the device that they're looking for.

2007-07-31[NET]: Call uninit if necessary in register_netdeviceHerbert Xu
This patch makes register_netdevice call dev->uninit if the regsitration fails after dev->init has completed successfully. Very few drivers use the init/uninit calls but at least one (drivers/net/wan/sealevel.c) may leak without this change. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2007-07-31[BLUETOOTH]: Fix endianness bug in l2cap_sock_listen()Al Viro
We loop through psm values, calling __l2cap_get_sock_by_addr(psm, ...) until we get NULL; then we set ->psm of our socket to htobs(psm). IOW, we find unused psm value and put it into our socket. So far, so good, but... __l2cap_get_sock_by_addr() compares its argument with ->psm of sockets. IOW, the entire thing works correctly only on little-endian. On big-endian we'll get "no socket with such psm" on the first iteration, since we won't find a socket with ->psm == 0x1001. We will happily conclude that 0x1001 is unused and slap htobs(0x1001) (i.e. 0x110) into ->psm of our socket. Of course, the next time around the same thing will repeat and we'll just get a fsckload of sockets with the same ->psm assigned. Fix: pass htobs(psm) to __l2cap_get_sock_by_addr() there. All other callers are already passing little-endian values and all places that store something in ->psm are storing little-endian.

if printbuf allocation or tipc_node_attach_link() fails, invalid references to the link are left in the associated node and bearer structures.

2007-07-31[TCP]: htcp - use measured rttStephen Hemminger
Change HTCP to use measured RTT rather than smooth RTT. Srtt is computed using the TCP receive timestamp options, so it is vulnerable to hostile receivers. To avoid any problems this might cause use the measured RTT instead. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-31[TCP]: cubic - eliminate use of receive time stampStephen Hemminger
Remove use of received timestamp option value from RTT calculation in Cubic. A hostile receiver may be returning a larger timestamp option than the original value. This would cause the sender to believe the malevolent receiver had a larger RTT and because Cubic tries to provide some RTT friendliness, the sender would then favor the liar. Instead, use the jiffie resolutionRTT value already computed and passed back after ack. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-31[TCP]: congestion control API pass RTT in microsecondsStephen Hemminger
This patch changes the API for the callback that is done after an ACK is received. It solves a couple of issues: * Some congestion controls want higher resolution value of RTT (controlled by TCP_CONG_RTT_SAMPLE flag). These don't really want a ktime, but all compute a RTT in microseconds. * Other congestion control could use RTT at jiffies resolution. To keep API consistent the units should be the same for both cases, just the resolution should change. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.
