From fd184ab4283a6a6105e8312a497d2a2a193eaf67 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 24 May 2007 14:26:15 +0200 Subject: [Bluetooth] Always send HCI_Reset for Broadcom devices In case of Broadcom based Bluetooth devices, it is safe to always send HCI_Reset as first command. This gives the advantage that all HID Proxy versions will automatically work and don't need any additional quirks anymore.

POSIX do not defines behaviour for sys_setsockopt in case negative timeouts, but requires that setsockopt() shall fail with -EDOM if the send and receive timeout values are too big to fit into the timeout fields in the socket structure. In current implementation negative timeout can lead to error messages like "schedule_timeout: wrong timeout value". Proposed patch: - checks tv_usec and returns -EDOM if it is wrong - do not allows to set negative timeout values (sets 0 instead) and outputs ratelimited information message about such attempts.

Miller" Date: Thu, 24 May 2007 18:17:54 -0700 Subject: [XFRM]: Allow packet drops during larval state resolution. The current IPSEC rule resolution behavior we have does not work for a lot of people, even though technically it's an improvement from the -EAGAIN buisness we had before. Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S.
