* [ETH]: Combine format_addr() with print_mac().Michael Chan2008-01-281-3/+5
| | | | | | | | | | | | | | | | | | | print_mac() used many most net drivers and format_addr() used by net-sysfs.c are very similar and they can be intergrated. format_addr() is also identically redefined in the qla4xxx iscsi driver. Export a new function sysfs_format_mac() to be used by net-sysfs, qla4xxx and others in the future. Both print_mac() and sysfs_format_mac() call _format_mac_addr() to do the formatting. Changed print_mac() to use unsigned char * to be consistent with net_device struct's dev_addr. Added buffer length overrun checking as suggested by Joe Perches.

* [SOCK] Avoid divides in sk_stream_pages() and __sk_stream_mem_reclaim()Eric Dumazet2008-01-281-1/+2
| | | | | | | | | | | | | | | | sk_forward_alloc being signed, we should take care of divides by SK_STREAM_MEM_QUANTUM we do in sk_stream_pages() and __sk_stream_mem_reclaim() This patchs introduces SK_STREAM_MEM_QUANTUM_SHIFT, defined as ilog2(SK_STREAM_MEM_QUANTUM), to be able to use right shifts instead of plain divides. This should help compiler to choose right shifts instead of expensive divides (as seen with CONFIG_CC_OPTIMIZE_FOR_SIZE=y on x86) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [NETNS]: Modify the neighbour table code so it handles multiple network ↵Eric W. Biederman2008-01-281-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | namespaces I'm actually surprised at how much was involved. At first glance it appears that the neighbour table data structures are already split by network device so all that should be needed is to modify the user interface commands to filter the set of neighbours by the network namespace of their devices. However a couple things turned up while I was reading through the code. The proxy neighbour table allows entries with no network device, and the neighbour parms are per network device (except for the defaults) so they now need a per network namespace default. So I updated the two structures (which surprised me) with their very own network namespace parameter. Updated the relevant lookup and destroy routines with a network namespace parameter and modified the code that interacts with users to filter out neighbour table entries for devices of other namespaces. I'm a little concerned that we can modify and display the global table configuration and from all network namespaces. But this appears good enough for now. I keep thinking modifying the neighbour table to have per network namespace instances of each table type would should be cleaner. The hash table is already dynamically sized so there are it is not a limiter. The default parameter would be straight forward to take care of. However when I look at the how the network table is built and used I still find some assumptions that there is only a single neighbour table for each type of table in the kernel. The netlink operations, neigh_seq_start, the non-core network users that call neigh_lookup. So while it might be doable it would require more refactoring than my current approach of just doing a little extra filtering in the code. Signed-off-by: Eric W.

* [XFRM]: RFC4303 compliant auditingPaul Moore2008-01-281-7/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a number of new IPsec audit events to meet the auditing requirements of RFC4303. This includes audit hooks for the following events: * Could not find a valid SA [sections 2.1, 3.4.2] . xfrm_audit_state_notfound() . xfrm_audit_state_notfound_simple() * Sequence number overflow [section 3.3.3] . xfrm_audit_state_replay_overflow() * Replayed packet [section 3.4.3] . xfrm_audit_state_replay() * Integrity check failure [sections 3.4.4.1, 3.4.4.2] . xfrm_audit_state_icvfail() While RFC4304 deals only with ESP most of the changes in this patch apply to IPsec in general, i.e. both AH and ESP. The one case, integrity check failure, where ESP specific code had to be modified the same was done to the AH code for the sake of consistency.

* mac80211: allow easier multicast/broadcast buffering in hardwareJohannes Berg2008-01-281-0/+2
| | | | | | | | | | | | | | | | | There are various decisions influencing the decision whether to buffer a frame for after the next DTIM beacon. The "do we have stations in PS mode" condition cannot be tested by the driver so mac80211 has to do that. To ease driver writing for hardware that can buffer frames until after the next DTIM beacon, introduce a new txctl flag telling the driver to buffer a specific frame. While at it, restructure and comment the code for multicast buffering and remove spurious "inline" directives.
