| * xfrm: Assign esn pointers when cloning a stateSteffen Klassert2011-03-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | When we clone a xfrm state we have to assign the replay_esn and the preplay_esn pointers to the state if we use the new replay detection method. To this end, we add a xfrm_replay_clone() function that allocates memory for the replay detection and takes over the necessary values from the original state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem).

| * ipv4: Fix IP timestamp option (IPOPT_TS_PRESPEC) handling in ip_options_echo()Jan Luebbe2011-03-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current handling of echoed IP timestamp options with prespecified addresses is rather broken since the 2.2.x kernels. As far as i understand it, it should behave like when originating packets. Currently it will only timestamp the next free slot if: - there is space for *two* timestamps - some random data from the echoed packet taken as an IP is *not* a local IP This first is caused by an off-by-one error. 'soffset' points to the next free slot and so we only need to have 'soffset + 7 <= optlen'. The second bug is using sptr as the start of the option, when it really is set to 'skb_network_header(skb)'. I just use dptr instead which points to the timestamp option. Finally it would only timestamp for non-local IPs, which we shouldn't do. So instead we exclude all unicast destinations, similar to what we do in ip_options_compile().

| * ROSE: prevent heap corruption with bad facilitiesDan Rosenberg2011-03-271-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parsing the FAC_NATIONAL_DIGIS facilities field, it's possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure. Additionally, when parsing the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP facilities fields, a remote host can provide a length of less than 10, resulting in an underflow in a memcpy size, causing a kernel panic due to massive heap corruption. A length of greater than 20 results in a stack overflow of the callsign array. Abort facilities parsing on these invalid length values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 9435eb1cf0b76b323019cebf8d16762a50a12a19 ("ipv4: Implement __ip_dev_find using new interface address hash.") we reimplemented __ip_dev_find() so that it doesn't have to do a full FIB table lookup. Instead, it consults a hash table of addresses configured to interfaces. This works identically to the old code in all except one case, and that is for loopback subnets. The old code would match the loopback device for any IP address that falls within a subnet configured to the loopback device. Handle this corner case by doing the FIB lookup. We could implement this via inet_addr_onlink() but: 1) Someone could configure many addresses to loopback and inet_addr_onlink() is a simple list traversal. 2) We know the old code works.

It does not happen for cases when the primary address is also in another subnet. Fix that by deleting local and broadcast routes for all secondaries while they are on device list and by faking that all addresses from this subnet are to be deleted.

It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.

All callers that do not provide fc_prefsrc will ignore the route prefsrc as before and will delete the first occurence. That is how the ip route del default magic works. Current callers are: - ip_rt_ioctl where rtentry_to_fib_config provides fc_prefsrc only when the provided device name matches IP label with colon. - inet_rtm_delroute where RTA_PREFSRC is optional too - fib_magic which deals with routes when deleting addresses and where the fc_prefsrc is always set with the primary IP for the concerned IFA.

This stops including asm-generic/bitops/le.h directly and use ext2 non-atomic bit operations instead. It seems odd to use ext2_*_bit() on rds, but it will replaced with __{set,clear,test}_bit_le() after introducing little endian bit operations for all architectures. This indirect step is necessary to maintain bisectability for some architectures which have their own little-endian bit operations.
