netconsole: don't call __netpoll_cleanup() while atomic

2013-03-12T10:58:55Z

__netpoll_cleanup() is called in netconsole_netdev_event() while holding a spinlock. Release/acquire the spinlock before/after it and restart the loop. Also, disable the netconsole completely, because we won't have chance after the restart of the loop, and might end up in a situation where nt->enabled == 1 and nt->np.dev == NULL.

netpoll: add IPv6 support

2013-01-09T01:56:10Z

Currently, netpoll only supports IPv4. This patch adds IPv6 support to netpoll so that we can run netconsole over IPv6 network. Cc: David S. Miller Signed-off-by: Cong Wang Signed-off-by: David S. Miller

netconsole: add oops_only module option

2012-11-09T03:06:36Z

Some people wants to log only oops messages via netconsole, (this is also why netoops was invented) so add a module option for netconsole. This can be tuned via /sys/module/netconsole/parameters/oops_only at run time as well. Cc: David Miller Signed-off-by: Cong Wang Signed-off-by: David S. Miller

netconsole: remove a redundant netconsole_target_put()

2012-08-20T09:59:49Z

This netconsole_target_put() is obviously redundant, and it causes a kernel segfault when removing a bridge device which has netconsole running on it. This is caused by: commit 8d8fc29d02a33e4bd5f4fa47823c1fd386346093 Author: Amerigo Wang Date: Thu May 19 21:39:10 2011 +0000 netpoll: disable netpoll when enslave a device Cc: David Miller (for all 3.x stable releases) Cc: stable@vger.kernel.org Signed-off-by: Cong Wang Signed-off-by: David S.

netconsole: do not release spin_lock when calling __netpoll_cleanup

2012-08-14T21:33:31Z

With the previous patch applied, __netpoll_cleanup() is non-block now, so we don't need to release the spin_lock before calling it. Cc: "David S. Miller" Signed-off-by: Cong Wang Signed-off-by: David S. Miller

drivers/net: Remove unnecessary k.alloc/v.alloc OOM messages

2012-01-31T21:20:21Z

alloc failures use dump_stack so emitting an additional out-of-memory message is an unnecessary duplication. Remove the allocation failure messages. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

netconsole: enable netconsole can make net_device refcnt incorrent

2011-10-19T03:55:29Z

There is no check if netconsole is enabled current. so when exec echo 1 > enabled; the reference of net_device will increment always. Signed-off-by: Gao feng Acked-by: Flavio Leitner Signed-off-by: David S. Miller

netconsole: switch init_netconsole() to late_initcall

2011-09-20T19:45:07Z

Commit 88491d8(drivers/net: Kconfig & Makefile cleanup) causes a regression that netconsole does not work if netconsole and network device driver are build into kernel, because netconsole is linked before network device driver. Andrew Morton suggested to fix this with initcall ordering. Fixes it by switching init_netconsole() to late_initcall. Signed-off-by: Lin Ming Signed-off-by: David S. Miller
