2007-02-26[XFRM]: Fix oops in xfrm4_dst_destroy()Bernhard Walle1-1/+1
With 2.6.21-rc1, I get an oops when running 'ifdown eth0' and an IPsec connection is active. If I shut down the connection before running 'ifdown eth0', then there's no problem. The critical operation of this script is to kill dhcpd. The problem is probably caused by commit with git identifier 4337226228e1cfc1d70ee975789c6bd070fb597c (Linus tree) "[IPSEC]: IPv4 over IPv6 IPsec tunnel". This patch fixes that oops. I don't know the network code of the Linux kernel in deep, so if that fix is wrong, please change it. But please fix the oops. :) Signed-off-by: Bernhard Walle <bwalle@suse.de> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-02-26[SCTP]: Fix connection hang/slowdown with PR-SCTPVlad Yasevich1-5/+22
The problem that this patch corrects happens when all of the following conditions are satisfisfied: 1. PR-SCTP is used and the timeout on the chunks is set below RTO.Max. 2. One of the paths on a multihomed associations is brought down. In this scenario, data will expire within the rto of the initial transmission and will never be retransmitted. However this data still fills the send buffer and is counted against the association as outstanding data. This causes any new data not to be sent and retransmission to not happen. The fix is to discount the abandoned data from the outstanding count and peers rwnd estimation. This allows new data to be sent and a retransmission timer restarted. Even though this new data will most likely expire within the rto, the timer still counts as a strike against the transport and forces the FORWARD-TSN chunk to be retransmitted as well.

2007-02-20[PATCH] Convert highest_possible_processor_id to nr_cpu_idsChristoph Lameter2-7/+4
We frequently need the maximum number of possible processors in order to allocate arrays for all processors. So far this was done using highest_possible_processor_id(). However, we do need the number of processors not the highest id. Moreover the number was so far dynamically calculated on each invokation. The number of possible processors does not change when the system is running. We can therefore calculate that number once.

2007-02-20[PATCH] Replace highest_possible_node_id() with nr_node_idsChristoph Lameter1-2/+2
highest_possible_node_id() is currently used to calculate the last possible node idso that the network subsystem can figure out how to size per node arrays. I think having the ability to determine the maximum amount of nodes in a system at runtime is useful but then we should name this entry correspondingly, it should return the number of node_ids, and the the value needs to be setup only once on bootup. The node_possible_map does not change after bootup. This patch introduces nr_node_ids and replaces the use of highest_possible_node_id(). nr_node_ids is calculated on bootup when the page allocators pagesets are initialized.

2007-02-14[PATCH] ieee80211softmac: Fix setting of initial transmit ratesLarry Finger2-18/+6
There is a bug in ieee80211softmac that always sets the user rate to 11Mbs, no matter the capabilities of the device. This bug was probably beneficial as long as the bcm43xx cards were rate limited; however, most are now capable of relatively high speeds. This patch fixes that bug and eliminates an assert that is no longer needed. Once the cards are capable of full OFDM speeds, the 24 Mbs rate will be changed to 54 Mbs.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman30-32/+32
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

register_sysctl_table There has not been much maintenance on sysctl in years, and as a result is there is a lot to do to allow future interesting work to happen, and being ambitious I'm trying to do it all at once :) The patches in this series fall into several general categories. - Removal of useless attempts to override the standard sysctls - Registers of sysctl numbers in sysctl.h so someone else does not use the magic number and conflict. - C99 conversions so it becomes possible to change the layout of struct ctl_table without breaking everything. - Removal of useless claims of module ownership, in the proc dir entries - Removal of sys_sysctl support where people had used conflicting sysctl numbers. Trying to break glibc or other applications by changing the ABI is not cool. 9 instances of this in the kernel seems a little extreme. - General enhancements when I got the junk I could see out. This patch: Since x25 uses unique binary numbers inserting yourself at the head of the search list for sysctls so you can override already registered sysctls is pointless. Signed-off-by: Eric W.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau135-135/+1
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

authentication AUTH_UNIX authentication (the standard with NFS) has a limit of 16 groups ids. This causes problems for people in more than 16 groups. So allow the server to map a uid into a list of group ids based on local knowledge rather depending on the (possibly truncated) list from the client. If there is no process on the server responding to upcalls, the gidlist in the request will still be used.
