| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed while looking into some odd behavior in sctp, that the variable name sctp_pf_inet6_specific was used twice to represent two different pieces of data (its both a structure name and a pointer to that type of structure), which is confusing to say the least, and potentially dangerous depending on the variable scope. This patch cleans that up, and makes the protocol and address family registration names in SCTP more regular, increasing readability.

* | [IPCOMP]: Disable BH on output when using shared tfmHerbert Xu2008-02-282-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Because we use shared tfm objects in order to conserve memory, (each tfm requires 128K of vmalloc memory), BH needs to be turned off on output as that can occur in process context. Previously this was done implicitly by the xfrm output code. That was lost when it became lockless. So we need to add the BH disabling to IPComp directly.

* | [INET]: Don't create tunnels with '%' in name.Pavel Emelyanov2008-02-264-18/+38
|/ | | | | | | | | | | | | | | | | | Four tunnel drivers (ip_gre, ipip, ip6_tunnel and sit) can receive a pre-defined name for a device from the userspace. Since these drivers call the register_netdevice() (rtnl_lock, is held), which does _not_ generate the device's name, this name may contain a '%' character. Not sure how bad is this to have a device with a '%' in its name, but all the other places either use the register_netdev(), which call the dev_alloc_name(), or explicitly call the dev_alloc_name() before registering, i.e. do not allow for such names. This had to be prior to the commit 34cc7b, but I forgot to number the patches and this one got lost, sorry. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

This also fixes an OOPS after module unload in that the name string for remove was wrong, so it wouldn't actually be removed.

* [IPV4]: Reset scope when changing addressBjorn Mork2008-02-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | This bug did bite at least one user, who did have to resort to rebooting the system after an "ifconfig eth0 127.0.0.1" typo. Deleting the address and adding a new is a less intrusive workaround. But I still beleive this is a bug that should be fixed. Some way or another. Another possibility would be to remove the scope mangling based on address. This will always be incomplete (are 127/8 the only address space with host scope requirements?) We set the scope to RT_SCOPE_HOST if an IPv4 interface is configured with a loopback address (127/8). The scope is never reset, and will remain set to RT_SCOPE_HOST after changing the address. This patch resets the scope if the address is changed again, to restore normal functionality. Signed-off-by: Bjorn Mork <bjorn@mork.no> Signed-off-by: David S. Miller <davem@davemloft.net>

For this purpose do_setlink() is called which expects address attributes with a payload length of at least dev->addr_len. This patch adds the necessary validation for the RTM_NEWLINK case. The address length for links to be created is not checked for now as the actual attribute length is used when copying the address to the netdevice structure. It might make sense to report an error if less than addr_len bytes are provided but enforcing this might break drivers trying to be smart with not transmitting all zero addresses.

* | PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* | Wrap buffers used for rpc debug printks into RPC_IFDEBUGPavel Emelyanov2008-02-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sorry for the noise, but here's the v3 of this compilation fix :) There are some places, which declare the char buf[...] on the stack to push it later into dprintk(). Since the dprintk sometimes (if the CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers cause gcc to produce appropriate warnings. Wrap these buffers with RPC_IFDEBUG macro, as Trond proposed, to compile them out when not needed. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Acked-by: J.
