2012-08-09time: jiffies_delta_to_clock_t() helper to the rescueEric Dumazet
Various /proc/net files sometimes report crazy timer values, expressed in clock_t units. This happens when an expired timer delta (expires - jiffies) is passed to jiffies_to_clock_t(). This function has an overflow in : return div_u64((u64)x * TICK_NSEC, NSEC_PER_SEC / USER_HZ); commit cbbc719fccdb8cb (time: Change jiffies_to_clock_t() argument type to unsigned long) only got around the problem. As we cant output negative values in /proc/net/tcp without breaking various tools, I suggest adding a jiffies_delta_to_clock_t() wrapper that caps the negative delta to a 0 value.

2011-03-14bridge: control carrier based on ports onlinestephen hemminger
This makes the bridge device behave like a physical device. In earlier releases the bridge always asserted carrier. This changes the behavior so that bridge device carrier is on only if one or more ports are in the forwarding state. This should help IPv6 autoconfiguration, DHCP, and routing daemons. I did brief testing with Network and Virt manager and they seem fine, but since this changes behavior of bridge, it should wait until net-next (2.6.39).

2010-05-15bridge: change console message interfacestephen hemminger
Use one set of macro's for all bridge messages. Note: can't use netdev_XXX macro's because bridge is purely virtual and has no device parent. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-31[BRIDGE]: Round off STP perodic timers.Stephen Hemminger
Peroidic STP timers don't have to be exact. The hold timer runs at 1HZ, and the hello timer normally runs at 2HZ; save power by aligning it them to next second. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
