2008-11-06net: Fix recursive descent in __scm_destroy().David S. Miller1-3/+21
__scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

2008-11-06Fix logic error in rfkill_check_duplicityJonathan McDowell1-1/+1
> I'll have a prod at why the [hso] rfkill stuff isn't working next Ok, I believe this is due to the addition of rfkill_check_duplicity in rfkill and the fact that test_bit actually returns a negative value rather than the postive one expected (which is of course equally true). So when the second WLAN device (the hso device, with the EEE PC WLAN being the first) comes along rfkill_check_duplicity returns a negative value and so rfkill_register returns an error.

2008-11-05p9: Fix leak of waitqueue in request allocation pathTom Tucker1-0/+3
If a T or R fcall cannot be allocated, the function returns an error but neglects to free the wait queue that was successfully allocated. If it comes through again a second time this wq will be overwritten with a new allocation and the old allocation will be leaked. Also, if the client is subsequently closed, the close path will attempt to clean up these allocations, so set the req fields to NULL to avoid duplicate free.

2008-11-05ipv6: fix run pending DAD when interface becomes readyBenjamin Thery1-1/+3
With some net devices types, an IPv6 address configured while the interface was down can stay 'tentative' forever, even after the interface is set up. In some case, pending IPv6 DADs are not executed when the device becomes ready. I observed this while doing some tests with kvm. If I assign an IPv6 address to my interface eth0 (kvm driver rtl8139) when it is still down then the address is flagged tentative (IFA_F_TENTATIVE). Then, I set eth0 up, and to my surprise, the address stays 'tentative', no DAD is executed and the address can't be pinged. I also observed the same behaviour, without kvm, with virtual interfaces types macvlan and veth. Some easy steps to reproduce the issue with macvlan: 1. ip link add link eth0 type macvlan 2. ip -6 addr add 2003::ab32/64 dev macvlan0 3. ip addr show dev macvlan0 ... inet6 2003::ab32/64 scope global tentative ... 4. ip link set macvlan0 up 5. ip addr show dev macvlan0 ... inet6 2003::ab32/64 scope global tentative ... Address is still tentative I think there's a bug in net/ipv6/addrconf.c, addrconf_notify(): addrconf_dad_run() is not always run when the interface is flagged IF_READY. Currently it is only run when receiving NETDEV_CHANGE event. Looks like some (virtual) devices doesn't send this event when becoming up. For both NETDEV_UP and NETDEV_CHANGE events, when the interface becomes ready, run_pending should be set to 1. Patch below. 'run_pending = 1' could be moved below the if/else block but it makes the code less readable. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S.

Endpoint A Endpoint B UDP Echo request -----------> (IPv4, Dst port=7) <---------- UDP Echo Reply (IPv4, Src port=7) This bug is come from this patch cb75994ec311b2cd50e5205efdcc0696abd6675d. It do counter UDP[6]_MIB_INDATAGRAMS until udp[v6]_recvmsg. Because xinetd used IPv6 socket to receive UDP messages, thus, when received UDP packet, the UDP6_MIB_INDATAGRAMS will be increased in function udpv6_recvmsg() even if the packet is a IPv4 UDP packet.

Commit 04a4bb55bcf35b63d40fd2725e58599ff8310dd7 ("net: add skb_recycle_check() to enable netdriver skb recycling") added a method for network drivers to recycle skbuffs, but while use of this mechanism was documented in the commit message, it should really have been added as a docbook comment as well -- this patch does that.

2008-11-01saner FASYNC handling on file closeAl Viro1-1/+0
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-10-31xfrm: do not leak ESRCH to user spacefernando@oss.ntt.co1-0/+2
I noticed that, under certain conditions, ESRCH can be leaked from the xfrm layer to user space through sys_connect. In particular, this seems to happen reliably when the kernel fails to resolve a template either because the AF_KEY receive buffer being used by racoon is full or because the SA entry we are trying to use is in XFRM_STATE_EXPIRED state. However, since this could be a transient issue it could be argued that EAGAIN would be more appropriate. Besides this error code is not even documented in the man page for sys_connect (as of man-pages 3.07). Signed-off-by: Fernando Luis Vazquez Cao <fernando@oss.ntt.co.jp> Signed-off-by: David S.

2008-10-30netfilter: nf_conntrack_proto_gre: switch to register_pernet_gen_subsys()Alexey Dobriyan1-2/+2
register_pernet_gen_device() can't be used is nf_conntrack_pptp module is also used (compiled in or loaded). Right now, proto_gre_net_exit() is called before nf_conntrack_pptp_net_exit(). The former shutdowns and frees GRE piece of netns, however the latter absolutely needs it to flush keymap. Oops is inevitable. Switch to shiny new register_pernet_gen_subsys() to get correct ordering in netns ops list.

2008-10-30netns: add register_pernet_gen_subsys/unregister_pernet_gen_subsysAlexey Dobriyan1-0/+32
netns ops which are registered with register_pernet_gen_device() are shutdown strictly before those which are registered with register_pernet_subsys(). Sometimes this leads to opposite (read: buggy) shutdown ordering between two modules. Add register_pernet_gen_subsys()/unregister_pernet_gen_subsys() for modules which aren't elite enough for entry in struct net, and which can't use register_pernet_gen_device(). PPTP conntracking module is such one. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-10-28SUNRPC: Respond promptly to server TCP resetsTrond Myklebust1-10/+48
If the server sends us an RST error while we're in the TCP_ESTABLISHED state, then that will not result in a state change, and so the RPC client ends up hanging forever (see http://bugzilla.kernel.org/show_bug.cgi?id=11154) We can intercept the reset by setting up an sk->sk_error_report callback, which will then allow us to initiate a proper shutdown and retry... We also make sure that if the send request receives an ECONNRESET, then we shutdown too... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-10-26wireless: fix regression caused by regulatory config optionArjan van de Ven1-6/+5
The default for the regulatory compatibility option is wrong; if you picked the default you ended up with a non-functional wifi system (at least I did on Fedora 9 with iwl4965). I don't think even the October 2008 releases of the various distros has the new userland so clearly the default is wrong, and also we can't just go about deleting this in 2.6.29... Change the default to "y" and also adjust the config text a little to reflect this.
