2008-11-30Bluetooth: Enable per-module dynamic debug messagesMarcel Holtmann1-2/+2
With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to allow debugging without having to recompile the kernel. This patch turns all BT_DBG() calls into pr_debug() to support dynamic debug messages. As a side effect all CONFIG_BT_*_DEBUG statements are now removed and some broken debug entries have been fixed.

2008-11-30Bluetooth: Send HCI Reset command by default on device initializationMarcel Holtmann1-1/+1
The Bluetooth subsystem was not using the HCI Reset command when doing device initialization. The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2008-11-26net: Fix soft lockups/OOM issues w/ unix garbage collectordann frazier1-0/+1
This is an implementation of David Miller's suggested fix in: https://bugzilla.redhat.com/show_bug.cgi?id=470201 It has been updated to use wait_event() instead of wait_event_interruptible(). Paraphrasing the description from the above report, it makes sendmsg() block while UNIX garbage collection is in progress. This avoids a situation where child processes continue to queue new FDs over a AF_UNIX socket to a parent which is in the exit path and running garbage collection on these FDs. This contention can result in soft lockups and oom-killing of unrelated processes. Signed-off-by: dann frazier <dannf@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-26pkt_sched: gen_estimator: Optimize gen_estimator_active()Jarek Poplawski1-2/+2
Since all other gen_estimator functions use bstats and rate_est params together, and searching for them is optimized now, let's use this also in gen_estimator_active(). The return type of gen_estimator_active() is changed to bool, and gen_find_node() parameters to const, btw. In tcf_act_police_locate() a check for ACT_P_CREATED is added before calling gen_estimator_active(). Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S.

Note : We revert commit (248969ae31e1b3276fc4399d67ce29a5d81e6fd9 net: af_unix can make unix_nr_socks visbile in /proc), since it is not anymore used after sock_prot_inuse_add() addition Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2008-11-25tc: policing requires a rate estimatorStephen Hemminger1-0/+1
Found that while trying average rate policing, it was possible to request average rate policing without a rate estimator. This results in no policing which is harmless but incorrect. Since policing could be setup in two steps, need to check in the kernel. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-11-25netns xfrm: per-netns sysctlsAlexey Dobriyan3-5/+20

For that make net_core_path[] global, register it to prevent two /proc/net/core antries and change initcall position -- xfrm_init() is called from fs_initcall, so this one should be fs_initcall at least.
