* [PATCH] files: lock-free fd look-upDipankar Sarma2005-09-09
| | | | | | | | | | | | 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(). This patch changes the readers to use lock-free lookup.

| * [IPV4]: Fix refcount damaging in net/ipv4/route.cJulian Anastasov2005-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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...

* | [PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan2005-09-07
|/ | | | | | | | | | | | | | | | | | | | | | | | | 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.
