2005-09-09[PATCH] files: lock-free fd look-upDipankar Sarma
With the use of RCU in files structure, the look-up of files using fds can now be lock-free. The lookup is protected by rcu_read_lock()/rcu_read_unlock().

2005-09-09[DCCP] Give precedence to the biggest ELAPSED_TIMEArnaldo Carvalho de Melo
We can get this value in an TIMESTAMP_ECHO and/or in an ELAPSED_TIME option, if receiving both give precendence to the biggest one. In my tests they are very close if not equal at all times, so we may well think about removing the code in CCID3 that inserts this option and leaving this to the core, and perhaps even use just TIMESTAMP_ECHO including the elapsed time.

We should not restrict use of ieee80211 to only when wireless drivers are enabled. In-development and out-of-tree drivers may wish to use it, and by removing this restriction we eliminate a circular dependency.
2005-09-08[AX.25]: Make asc2ax() thread-proofRalf Baechle
Asc2ax was still using a static buffer for all invocations which isn't exactly SMP-safe. Change asc2ax to take an additional result buffer as the argument.

2005-09-08[IPV4]: Fix refcount damaging in net/ipv4/route.cJulian Anastasov
One such place that can damage the dst refcnts is route.c with CONFIG_IP_ROUTE_MULTIPATH_CACHED enabled, i don't see the user's .config. In this new code i see that rt_intern_hash is called before dst->refcnt is set to 1, dst is the 2nd arg to rt_intern_hash. Arg 2 of rt_intern_hash must come with refcnt 1 as it is added to table or dropped depending on error/add/update. One such example is ip_mkroute_input where __mkroute_input return rth with refcnt 0 which is provided to rt_intern_hash. ip_mkroute_output looks like a 2nd such place. Appending untested patch for comments and review. The idea is to put previous reference as we are going to return next result/error.

2005-09-08[IPV4] udp: trim forgets about CHECKSUM_HWStephen Hemminger
A UDP packet may contain extra data that needs to be trimmed off. But when doing so, UDP forgets to fixup the skb checksum if CHECKSUM_HW is being used. I think this explains the case of a NFS receive using skge driver causing 'udp hw checksum failures' when interacting with a crufty settop box.

2005-09-08[PATCH] Fix 32bit sendmsg() flawAl Viro
When we copy 32bit ->msg_control contents to kernel, we walk the same userland data twice without sanity checks on the second pass. Second version of this patch: the original broke with 64-bit arches running 32-bit-compat-mode executables doing sendmsg() syscalls with unaligned CMSG data areas Another thing is that we use kmalloc() to allocate and sock_kfree_s() to free afterwards; less serious, but also needs fixing.

2005-09-07[PATCH] sunrpc: print unsigned integers in statsMax Kellermann
The sunrpc stats are collected in unsigned integers, but they are printed with '%d'. That can result in negative numbers in /proc/net/rpc when the highest bit of a counter is set.

2005-09-07[PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan
When registering an RPC cache, cache_register() always sets the owner as the sunrpc module. However, there are RPC caches owned by other modules. With the incorrect owner setting, the real owning module can be removed potentially with an open reference to the cache from userspace. For example, if one were to stop the nfs server and unmount the nfsd filesystem, the nfsd module could be removed eventhough rpc.idmapd had references to the idtoname and nametoid caches (i.e. /proc/net/rpc/nfs4.<cachename>/channel is still open). This resulted in a system panic on one of our machines when attempting to restart the nfs services after reloading the nfsd module. The following patch adds a 'struct module *owner' field in struct cache_detail. The owner is further assigned to the struct proc_dir_entry in cache_register() so that the module cannot be unloaded while user-space daemons have an open reference on the associated file under /proc.

2005-09-06[PATCH] WE-19 for kernel 2.6.13Jean Tourrilhes
Hi Jeff, This is version 19 of the Wireless Extensions. It was supposed to be the fallback of the WPA API changes, but people seem quite happy about it (especially Jouni), so the patch is rather small. The patch has been fully tested with 2.6.13 and various wireless drivers, and is in its final version. Would you mind pushing that into Linus's kernel so that the driver and the apps can take advantage ot it ? It includes : o iwstat improvement (explicit dBm). This is the result of long discussions with Dan Williams, the authors of NetworkManager. Thanks to him for all the fruitful feedback. o remove pointer from event stream. I was not totally sure if this pointer was 32-64 bits clean, so I'd rather remove it and be at peace with it. o remove linux header from wireless.h. This has long been requested by people writting user space apps, now it's done, and it was not even painful. o final deprecation of spy_offset. You did not like it, it's now gone for good. o Start deprecating dev->get_wireless_stats -> debloat netdev o Add "check" version of event macros for ieee802.11 stack. Jiri Benc doesn't like the current macros, we aim to please ;-) All those changes, except the last one, have been bit-roting on my web pages for a while... Patches for most kernel drivers will follow. Patches for the Orinoco and the HostAP drivers have been sent to their respective maintainers. Have fun...

2005-09-06[NETFILTER]: Handle NAT module load racePatrick McHardy
When the NAT module is loaded when connections are already confirmed it must not change their tuples anymore.
