* sky2: fix regression on Yukon Optimastephen hemminger2011-11-04
| | | | | | | | | | | | | | Changes to support other Optima types, introduced an accidental regression that caused 88E8059 to come up in 10Mbit/sec. The Yukon Optima supports a reverse auto-negotiation feature that was incorrectly setup, and not needed. The feature could be used to allow wake-on-lan at higher speeds. But doing it correctly would require other changes to initialization. Reported-by: Pavel Mateja <pavel@netsafe.cz> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

* netlink: validate NLA_MSECS lengthJohannes Berg2011-11-04
| | | | | | | | | | | | | | | | | | | | | | L2TP for example uses NLA_MSECS like this: policy: [L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, }, code: if (info->attrs[L2TP_ATTR_RECV_TIMEOUT]) cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]); As nla_get_msecs() is essentially nla_get_u64() plus the conversion to a HZ-based value, this will not properly reject attributes from userspace that aren't long enough and might overrun the message. Add NLA_MSECS to the attribute minlen array to check the size properly.

* macvlan: receive multicast with local addressstephen hemminger2011-11-04
| | | | | | | | | | | | | | | | | | | | | | | | When implementing VRRP v2 using macvlan several problems were discovered. VRRP is weird in that all routers participating in a redundant group use the same virtual MAC address. Macvlan is a natural driver to use for this but it doesn't work. The problem is that packets with a macvlan device's source address are not received. The problem is actually a regression that date back almost 2 years now. The original problems started with: commit 618e1b7482f7a8a4c6c6e8ccbe140e4c331df4e9 Author: Arnd Bergmann <arnd@arndb.de> Date: Thu Nov 26 06:07:10 2009 +0000 macvlan: implement bridge, VEPA and private mode This patches restores the original 2.6.32 behavior.

* tg3: Eliminate timer race with reset_taskMatt Carlson2011-11-04
| | | | | | | | | | | | | | During shutdown, it is impossible to reliably disable the timer and reset_task threads. Each thread can schedule the other, which leads to shutdown code that chases its tail. To fix the problem, this patch removes the ability of tg3_reset_task to schedule a new timer thread. To support this change, tg3_timer no longer terminates itself, but rather goes into a polling mode.

* tg3: Schedule at most one tg3_reset_task runMatt Carlson2011-11-04
| | | | | | | | | | | | | | | | | It is possible for multiple threads in the tg3 driver to each attempt to schedule a run of tg3_reset_task(). The multiple tg3_reset_task executions could all wind up on the same queue (and execute serially) or wind up on the queues of another processor (which could execute in parallel). Either scenario is not what was truly desired. This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to determine whether or not to schedule another run of tg3_reset_task(). With the new flag comes two new functions to facilitate scheduling and descheduling of tg3_reset_task().

* tg3: Fix 4k tx bd segmentation codeMatt Carlson2011-11-04
| | | | | | | | | | | | | | The new 4k tx bd segmentation code had a bug in the error cleanup path. If the driver did not map all the physical fragments, the abort path would wind up advancing the producer index beyond the point where the setup code stopped. This would ultimately turn into a tx recovery error where the driver would expect the skb pointer to be set when it isn't. This patch fixes the problem, and then makes the code a little easier to understand.

* tg3: Fix APE mutex init and useMatt Carlson2011-11-04
| | | | | | | | | | | | | | APE mutex register blocks are shared by all ports of multiport devices. For some mutexing purposes, each function is assigned their own register. For other cases, each function is assigned its own request and grant bits of a single register. For the latter cases, the tg3 driver is incorrectly allowing each function to use the same set of grant / request bits. This patch fixes the code so that each function uses the appropriate bitset.

However, it assumes that the scan request was allocated via the cfg80211 stack. Libertas has its own internal allocation method, kept track of with priv->internal_scan. This doesn't set scan_req->wiphy, amongst other things, which results in hitting a BUG() when we call cfg80211_scan_done on the request. This provides a function to take care of the low-level scan_req cleanup details. We simply call that to deal with finishing up scan requests.

It looks like I get two HCI reset command complete events (see hcidump logs below). The root cause is reset called from off_timer. Timeout for this reset to complete is set to 250ms and my bt dongle requires more time for replying with command complete event. After that, chip seems to reply with reset command complete event for next non-reset command. Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is already used for timeouting hci_reset_req in hci_dev_reset(). This might also be related to BT not working after suspend that was reported here some time ago.

| | | * Bluetooth: rfcomm: Fix sleep in invalid context in rfcomm_security_cfmSzymon Janc2011-10-14

Move closing DLC to rfcomm_process_dlcs and only flag DLC for closure in rfcomm_security_cfm.

This change refactors that code so that a hardware-specific, but OS- and application-agnostic header, is created: <arch/opcode.h>. This header is then exported to userspace along with the other <arch> headers and can be used to build userspace code; in particular, it is used by glibc as part of implementing the backtrace() function. The new header, together with a header that specifically describes the disassembly code (<asm/tile-desc.h> with _32 and _64 variants), replaces the old <asm/opcode-tile*.h> and <asm/opcode_constants*.h> headers. As part of this change, we are also renaming the 32-bit constants from TILE_xxx to TILEPRO_xxx to better reflect the fact that they are specific to the TILEPro architecture, and not to TILE-Gx and any successor "tile" architecture chips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These headers are similar to the <asm> headers that describe kernel APIs, but instead describe aspects of the actual hardware in an OS- and application-independent manner. We need to include them in the set of installed headers so that userspace tools (including glibc) can build purely from the provided kernel headers. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
| * | | | arch/tile: avoid exporting a symbol no longer used by gccChris Metcalf2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An earlier Tilera compiler generated calls to an "__ll_mul" function for long long multiplication. Our libgcc supported that as an alias for the normal __muldi3 routine, so we made it available to kernel modules as well. However, for a while now the compiler has internally been generating only the standard __muldi3 symbol, and the version we are giving back to the community does not have the __ll_mul alias, so we are removing it from the kernel too.

| * | | | arch/tile: avoid ISO namespace pollution with <asm/sigcontext.h>Chris Metcalf2011-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <asm/sigcontext.h> is used by glibc's <bits/sigcontext.h> from <signal.h>, which means that it can't clutter the namespace with random symbols or #defines. However, we use <arch/abi.h> to get a suitable type to hold a machine register. This change makes <arch/abi.h> safe to use in this kind of context if __need_int_reg_t is defined prior to including the file; in that case, it only defines a few symbols that are safe in the ISO namespace (prefixed with double underscores). <asm/sigcontext.h> then uses the __uint_reg_t type instead of the normal uint_reg_t.
