2009-02-24netlink: change nlmsg_notify() return value logicPablo Neira Ayuso2-2/+4
This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

2008-01-28[NETNS]: Modify the neighbour table code so it handles multiple network ↵Eric W. Biederman2-4/+4
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.

2008-01-28[NET]: Eliminate duplicate copies of dst_discardHerbert Xu1-12/+1
We have a number of copies of dst_discard scattered around the place which all do the same thing, namely free a packet on the input or output paths. This patch deletes all of them except dst_discard and points all the users to it. The only non-trivial bit is decnet where it returns an error. However, conceptually this is identical to the blackhole functions used in IPv4 and IPv6 which do not return errors. So they should either all return errors or all return zero. For now I've stuck with the majority and picked zero as the return value. It doesn't really matter in practice since few if any driver would react differently depending on a zero return value or NET_RX_DROP.

2007-11-07[DECNET]: "addr" module param can't be __initdataAlexey Dobriyan1-1/+1
sysfs keeps references to module parameters via /sys/module/*/parameters, so marking them as __initdata can't work. Steps to reproduce: modprobe decnet cat /sys/module/decnet/parameters/addr BUG: unable to handle kernel paging request at virtual address f88cd410 printing eip: c043dfd1 *pdpt = 0000000000004001 *pde = 0000000004408067 *pte = 0000000000000000 Oops: 0000 [#1] PREEMPT SMP Modules linked in: decnet sunrpc af_packet ipv6 binfmt_misc dm_mirror dm_multipath dm_mod sbs sbshc fan dock battery backlight ac power_supply parport loop rtc_cmos serio_raw rtc_core rtc_lib button amd_rng sr_mod cdrom shpchp pci_hotplug ehci_hcd ohci_hcd uhci_hcd usbcore Pid: 2099, comm: cat Not tainted (2.6.24-rc1-b1d08ac064268d0ae2281e98bf5e82627e0f0c56-bloat #6) EIP: 0060:[<c043dfd1>] EFLAGS: 00210286 CPU: 1 EIP is at param_get_int+0x6/0x20 EAX: c5c87000 EBX: 00000000 ECX: 000080d0 EDX: f88cd410 ESI: f8a108f8 EDI: c5c87000 EBP: 00000000 ESP: c5c97f00 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process cat (pid: 2099, ti=c5c97000 task=c641ee10 task.ti=c5c97000) Stack: 00000000 f8a108f8 c5c87000 c043db6b f8a108f1 00000124 c043de1a c043db2f f88cd410 ffffffff c5c87000 f8a16bc8 f8a16bc8 c043dd69 c043dd54 c5dd5078 c043dbc8 c5cc7580 c06ee64c c5d679f8 c04c431f c641f480 c641f484 00001000 Call Trace: [<c043db6b>] param_array_get+0x3c/0x62 [<c043de1a>] param_array_set+0x0/0xdf [<c043db2f>] param_array_get+0x0/0x62 [<c043dd69>] param_attr_show+0x15/0x2d [<c043dd54>] param_attr_show+0x0/0x2d [<c043dbc8>] module_attr_show+0x1a/0x1e [<c04c431f>] sysfs_read_file+0x7c/0xd9 [<c04c42a3>] sysfs_read_file+0x0/0xd9 [<c048d4b2>] vfs_read+0x88/0x134 [<c042090b>] do_page_fault+0x0/0x7d5 [<c048d920>] sys_read+0x41/0x67 [<c04080fa>] sysenter_past_esp+0x6b/0xc1 ======================= Code: 00 83 c4 0c c3 83 ec 0c 8b 52 10 8b 12 c7 44 24 04 27 dd 6c c0 89 04 24 89 54 24 08 e8 ea 01 0c 00 83 c4 0c c3 83 ec 0c 8b 52 10 <8b> 12 c7 44 24 04 58 8c 6a c0 89 04 24 89 54 24 08 e8 ca 01 0c EIP: [<c043dfd1>] param_get_int+0x6/0x20 SS:ESP 0068:c5c97f00 Signed-off-by: Alexey Dobriyan <adobriyan@sw.ru> Signed-off-by: David S.

2007-11-01[NET]: Forget the zero_it argument of sk_alloc()Pavel Emelyanov1-1/+1
Finally, the zero_it argument can be completely removed from the callers and from the function prototype. Besides, fix the checkpatch.pl warnings about using the assignments inside if-s. This patch is rather big, and it is a part of the previous one. I splitted it wishing to make the patches more readable. Hope this particular split helped.
