2009-10-12net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman36-21/+88
Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-08ipv6: Fix the size overflow of addrconf_sysctl arrayJin Dongming1-0/+1
(This patch fixes bug of commit f7734fdf61ec6bb848e0bafc1fb8bad2c124bb50 title "make TLLAO option for NA packets configurable") When the IPV6 conf is used, the function sysctl_set_parent is called and the array addrconf_sysctl is used as a parameter of the function. The above patch added new conf "force_tllao" into the array addrconf_sysctl, but the size of the array was not modified, the static allocated size is DEVCONF_MAX + 1 but the real size is DEVCONF_MAX + 2, so the problem is that the function sysctl_set_parent accessed wrong address. I got the following information. Call Trace: [<ffffffff8106085d>] sysctl_set_parent+0x29/0x3e [<ffffffff8106085d>] sysctl_set_parent+0x29/0x3e [<ffffffff8106085d>] sysctl_set_parent+0x29/0x3e [<ffffffff8106085d>] sysctl_set_parent+0x29/0x3e [<ffffffff8106085d>] sysctl_set_parent+0x29/0x3e [<ffffffff810622d5>] __register_sysctl_paths+0xde/0x272 [<ffffffff8110892d>] ? __kmalloc_track_caller+0x16e/0x180 [<ffffffffa00cfac3>] ? __addrconf_sysctl_register+0xc5/0x144 [ipv6] [<ffffffff8141f2c9>] register_net_sysctl_table+0x48/0x4b [<ffffffffa00cfaf5>] __addrconf_sysctl_register+0xf7/0x144 [ipv6] [<ffffffffa00cfc16>] addrconf_init_net+0xd4/0x104 [ipv6] [<ffffffff8139195f>] setup_net+0x35/0x82 [<ffffffff81391f6c>] copy_net_ns+0x76/0xe0 [<ffffffff8107ad60>] create_new_namespaces+0xf0/0x16e [<ffffffff8107afee>] copy_namespaces+0x65/0x9f [<ffffffff81056dff>] copy_process+0xb2c/0x12c3 [<ffffffff810576e1>] do_fork+0x14b/0x2d2 [<ffffffff8107ac4e>] ? up_read+0xe/0x10 [<ffffffff81438e73>] ? do_page_fault+0x27a/0x2aa [<ffffffff8101044b>] sys_clone+0x28/0x2a [<ffffffff81011fb3>] stub_clone+0x13/0x20 [<ffffffff81011c72>] ? system_call_fastpath+0x16/0x1b And the information of IPV6 in .config is as following.
