2008-07-03ipv6 addrconf: add accept_dad sysctl to control DAD operation.YOSHIFUJI Hideaki1-0/+7
- If 0, disable DAD. - If 1, perform DAD (default). - If >1, perform DAD and disable IPv6 operation if DAD for MAC-based link-local address has been failed (RFC4862 5.4.5). We do not follow RFC4862 by default. Refer to the netdev thread entitled "Linux IPv6 DAD not full conform to RFC 4862 ?" http://www.spinics.net/lists/netdev/msg52027.html Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>

2008-07-02icmp: fix units for ratelimitStephen Hemminger1-4/+6
Convert the sysctl values for icmp ratelimit to use milliseconds instead of jiffies which is based on kernel configured HZ. Internal kernel jiffies are not a proper unit for any userspace API.

2008-07-02ipv4: fix sysctl documentation of time related valuesStephen Hemminger1-8/+4
These sysctl values are time related and all use the same routine (proc_dointvec_jiffies) that internally converts from seconds to jiffies. The code is fine, the documentation is just wrong.

2006-12-03[TCP]: Restrict congestion control choices.Stephen Hemminger1-0/+6
Allow normal users to only choose among a restricted set of congestion control choices. The default is reno and what ever has been configured as default. But the policy can be changed by administrator at any time. For example, to allow any choice: cp /proc/sys/net/ipv4/tcp_available_congestion_control \ /proc/sys/net/ipv4/tcp_allowed_congestion_control Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.

2006-09-23[NetLabel]: documentationPaul Moore1-0/+35
Documentation for the NetLabel system, this includes a basic overview of how NetLabel works, how LSM developers can integrate it into their favorite LSM, as well as documentation on the CIPSO related sysctl variables. Also, due to the difficulty of finding expired IETF drafts, I am including the IETF CIPSO draft that is the basis of the NetLabel CIPSO implementation.

2006-09-18[TCP]: Turn ABC off.Stephen Hemminger1-3/+9
Turn Appropriate Byte Count off by default because it unfairly penalizes applications that do small writes.

Miller <davem@davemloft.net>
2006-08-18[NET]: Terminology in ip-sysctl.txtJan "Yenya" Kasprzak1-3/+3
this minor patch fixes the description of net.ipv4.tcp_mem sysctl in ip-sysctl.txt - the headline names the values "min, pressure, max", while the description uses the "low, pressure, high" values. Both tcp_rmem and tcp_wmem descriptions use the "min, pressure, max" values, so I have changed the tcp_mem to match this and not vice versa.

2006-06-18[TCP]: Add tcp_slow_start_after_idle sysctl.David S. Miller1-0/+7
A lot of people have asked for a way to disable tcp_cwnd_restart(), and it seems reasonable to add a sysctl to do that. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-21[TCP]: sysctl to allow TCP window > 32767 sans wscaleRick Jones1-0/+7
Back in the dark ages, we had to be conservative and only allow 15-bit window fields if the window scale option was not negotiated. Some ancient stacks used a signed 16-bit quantity for the window field of the TCP header and would get confused. Those days are long gone, so we can use the full 16-bits by default now. There is a sysctl added so that we can still interact with such old stacks Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-21[IPV4] ARP: Documentation for new arp_accept sysctl variable.Neil Horman1-0/+5

Taken largely from the commit of the patch that added this feature: 1c2fb7f93cb20621772bf304f3dba0849942e5db I'm not sure about the ordering of the options in sysctl.txt, so I took a wild guess about where it fits.

2006-01-04[IPV4]: Safer reassemblyHerbert Xu1-0/+23
Another spin of Herbert Xu's "safer ip reassembly" patch for 2.6.16. (The original patch is here: http://marc.theaimsgroup.com/?l=linux-netdev&m=112281936522415&w=2 and my only contribution is to have tested it.) This patch (optionally) does additional checks before accepting IP fragments, which can greatly reduce the possibility of reassembling fragments which originated from different IP datagrams.

2005-11-11[TCP]: Appropriate Byte Count supportStephen Hemminger1-0/+5
This is an updated version of the RFC3465 ABC patch originally for Linux 2.6.11-rc4 by Yee-Ting Li. ABC is a way of counting bytes ack'd rather than packets when updating congestion control. The orignal ABC described in the RFC applied to a Reno style algorithm. For advanced congestion control there is little change after leaving slow start.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+878
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!
