| * kbuild: a better way to generate cscope database changeDenis ChengRq2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's a problem about cscope target of kernel Makefile, and the cscope plugin of emacs: 1. `make cscope` will generate cscope.files cscope.{in,po,}.out; 2. the cscope plugin expect a cscope.out.{in,po,}; 3. the default `cscope -b` would generate cscope.{in,po,}.out; There are three approach to solve it: 1. modify the cscope C code; 2. modify the cscope emacs plugin lisp code; 3. modify the Makefile; I have tried to communicate with the cscope upstream, but later I realize the third approach is most meaningful.

| * Kconfig: Extend "menuconfig" for modules to simplify Kconfig fileRobert P. J. Day2008-08-06
| | | | | | | | | | | | | | | | | | | | Given that the init/Kconfig file uses a "menuconfig" directive for modules already, might as well wrap all the submenu entries in an "if" to toss all those dependencies.

| * kbuild: fix O=.. build with armSam Ravnborg2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a make O=... build kbuild would only create the include2/asm symlink for archs that not yet had moved headers to include/$ARCH/include There is no longer any reason to avoid the symlink for archs that has moved their headers so create it unconditionally. This fixes arm because kbuild checked for include/asm-$ARCH/errno.h and that file was not present for arm but the platform files are not yet moved.

| * Re-introduce "[SCSI] extend the last_sector_bug flag to cover more sectors"Linus Torvalds2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This re-introduces commit 2b142900784c6e38c8d39fa57d5f95ef08e735d8, which was reverted due to the regression it caused by commit fca082c9f1e11ec07efa8d2f9f13688521253f36. That regression was not root-caused by the original commit, it was just uncovered by it, and the real fix was done by Alan Stern in commit 580da34847488b404218d1d7f53b156f245f5555 ("Fix USB storage hang on command abort"). We can thus re-introduce the change that was confirmed by Alan Jenkins to be still required by his odd card reader.

This could either turn out to be instantaneous, or horribly slow depending on the load of the machine. As there is nothing preventing us from enabling forwarding straight away, this patch eliminates this potential delay by executing the code directly if the forward delay is zero. The effect of this problem is that immediately after the carrier comes on a port, the bridge will drop all packets received from that port until it enters forwarding mode, thus causing unnecessary packet loss. Note that this patch doesn't fully remove the delay due to the link watcher. We should also check the carrier state when we are about to drop an incoming packet because the port is disabled. But that's for another patch. -------------------- This version of the fix takes a different approach, in that it just does the state change directly. Signed-off-by: David S.

And now the reason has finally become apparent: It breaks TX capabilities As soon as the device has been associated all following TX frames will be queued in the hardware and never transmitted to the air. Disabling sections of the link tuner did not have the expected result, but completely disabling the link tuner did have the right result (Both of my rt2570 devices came back to life).

| | | * iwlwifi: Don't use buffer allocated on the stack for led namesSven Wegener2008-08-04

Not being able to resolve the name member of the led device structure to a meaningful value leads to confusion during ad-hoc debugging and potential breakage in the future, if we ever decide to access the name member outside of the registration function. Move the buffer to our private per led device structures so that it is accessible after registration. A quick grep didn't yield any occurence of using the led device name parameter outside of the led device registration function, so currently we should already be safe for normal operation.

The second hunk of the patch moves the tg3_set_power_state() call outside the critical section guarded by tg3_full_lock() and tg3_full_unlock() functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patrick McHardy <kaber@trash.net> noticed that it would be nice to handle NET_XMIT_BYPASS by NET_XMIT_SUCCESS with an internal qdisc flag __NET_XMIT_BYPASS and to remove the mapping from dev_queue_xmit().

Within a single qdisc this could be avoided by other means easily, upper qdiscs would still increase the counter when we return anything besides NET_XMIT_SUCCESS though. This means we need a new NET_XMIT return value to indicate this to the upper qdiscs. So I'd suggest to introduce NET_XMIT_STOLEN, return that to upper qdiscs and translate it to NET_XMIT_SUCCESS in dev_queue_xmit, similar to NET_XMIT_BYPASS." David Miller <davem@davemloft.net> noticed: "Maybe these NET_XMIT_* values being passed around should be a set of bits. They could be composed of base meanings, combined with specific attributes. So you could say "NET_XMIT_DROP | __NET_XMIT_NO_DROP_COUNT" The attributes get masked out by the top-level ->enqueue() caller, such that the base meanings are the only thing that make their way up into the stack. If it's only about communication within the qdisc tree, let's simply code it that way." This patch is trying to realize these ideas.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code will drop IPv6 packet if ipfragok is not set, since ipfragok is obsoleted, will be instead by used skb->local_df, so this check must be changed to skb->local_df. This patch fix this problem and not drop packet if skb->local_df is set to true.

The latter is only valid on IPv4. In fact, we never want to do the latter even on IPv4 when PMTU is enabled. This is because even though we can't fragment packets within SCTP due to the prtocol's inherent faults, we can still fragment it at IP layer. By setting the DF bit we will improve the PMTU process. RFC 2960 only says that we SHOULD clear the DF bit in this case, so we're compliant even if we set the DF bit. In fact RFC 4960 no longer has this statement. Once we make this change, we only need to control the local fragmentation. There is already a bit in the skb which controls that, local_df. So this patch sets that instead of using the ipfragok argument. The only complication is that there isn't a struct sock object per transport, so for IPv4 we have to resort to changing the pmtudisc field for every packet. This should be safe though as the protocol is single-threaded. Note that after this patch we can remove ipfragok from the rest of the stack too.
