2007-12-07[BRIDGE]: Section fix.Andrew Morton
WARNING: vmlinux.o(.init.text+0x204e2): Section mismatch: reference to .exit.text:br_fdb_fini (between 'br_init' and 'br_fdb_init') Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-08-30[BRIDGE]: Packets leaking out of disabled/blocked ports.Stephen Hemminger
This patch fixes some packet leakage in bridge. The bridging code was allowing forward table entries to be generated even if a device was being blocked. The fix is to not add forwarding database entries unless the port is active. The bug arose as part of the conversion to processing STP frames through normal receive path (in 2.6.17).

2007-07-20mm: Remove slab destructors from kmem_cache_create().Paul Mundt
Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

2007-05-31[BRIDGE]: Reduce frequency of forwarding cleanup timer in bridge.Baruch Even
The bridge cleanup timer is fired 10 times a second for timers that are at least 15 seconds ahead in time and that are not critical to be cleaned asap. This patch calculates the next time to run the timer as the minimum of all timers or a minimum based on the current state.

2007-04-25bridge: add sysfs hook to flush forwarding tableStephen Hemminger
The RSTP daemon needs to be able to flush all dynamic forwarding entries in the case of topology change. This is a temporary interface. It will change to a netlink interface before RSTP daemon is officially released. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org>
2007-04-25bridge: simpler hash with saltStephen Hemminger
Instead of hashing the whole Ethernet address, it should be faster to just use the last 4 bytes. Add a random salt value to the hash to make it more difficult to construct worst case DoS hash chains. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org>
2007-03-22[BRIDGE]: Fix fdb RCU racePatrick McHardy
br_fdb_get use atomic_inc to increase the refcount of an element found on a RCU protected list, which can lead to the following race: CPU0 CPU1 br_fdb_get: rcu_read_lock __br_fdb_get: find element fdb_delete: hlist_del_rcu br_fdb_put br_fdb_put: atomic_dec_and_test call_rcu(fdb_rcu_free) br_fdb_get: atomic_inc rcu_read_unlock fdb_rcu_free: kmem_cache_free Use atomic_inc_not_zero instead.

2006-12-07[PATCH] slab: remove kmem_cache_tChristoph Lameter
Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-10-15[BRIDGE]: flush forwarding table when device carrier offStephen Hemminger
Flush the forwarding table when carrier is lost. This helps for availability because we don't want to forward to a downed device and new packets may come in on other links. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-20[BRIDGE]: forwarding remove unneeded preempt and bh diasablesStephen Hemminger
Optimize the forwarding and transmit paths. Both places are called with bottom half/no preempt so there is no need to use spin_lock_bh or rcu_read_lock. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-08-29[NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointersEric Dumazet
This patch puts mostly read only data in the right section (read_mostly), to help sharing of these data between CPUS without memory ping pongs. On one of my production machine, tcp_statistics was sitting in a heavily modified cache line, so *every* SNMP update had to force a reload.

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!
