| | | | | | | | | | | | | | | | | | | | | | | | | | The original ARI support code has a compatibility problem with non-ARI devices. If a device doesn't support ARI, turning on ARI forwarding on its upper level bridge will cause undefined behavior. This fix turns on ARI forwarding only when the subordinate devices support it.

| * PCI hotplug: cpqphp: fix kernel NULL pointer dereferenceKenji Kaneshige2008-10-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch fixes the regression in 2.6.27 that causes kernel NULL pointer dereference at cpqphp driver probe time. This patch should be backported to the .27 stable series. Seems to have been introduced by f46753c5e354b857b20ab8e0fe7b2579831dc369. The root cause of this problem seems that cpqphp driver calls pci_hp_register() wrongly. In current implementation, cpqphp driver passes 'ctrl->pci_dev->subordinate' as a second parameter for pci_hp_register(). But because hotplug slots and it's hotplug controller (exists as a pci funcion) are on the same bus, it should be 'ctrl->pci_dev->bus' instead.

| * | tcp: Restore ordering of TCP options for the sake of inter-operabilityIlpo Järvinen2008-10-231-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is not our bug! Sadly some devices cannot cope with the change of TCP option ordering which was a result of the recent rewrite of the option code (not that there was some particular reason steming from the rewrite for the reordering) though any ordering of TCP options is perfectly legal. Thus we restore the original ordering to allow interoperability with/through such broken devices and add some warning about this trap. Since the reordering just happened without any particular reason, this change shouldn't cost us anything. There are already couple of known failure reports (within close proximity of the last release), so the problem might be more wide-spread than a single device. And other reports which may be due to the same problem though the symptoms were less obvious. Analysis of one of the case revealed (with very high probability) that sack capability cannot be negotiated as the first option (SYN never got a response).

So what happened was that it would simply take the TSO status of the last constituent device. This patch extends it to support both conjunctions and disjunctions under the new name of netdev_increment_features. It also adds a new function netdev_fix_features which does the sanity checking that usually occurs upon registration. This ensures that the computation doesn't result in an illegal combination since this checking is absent when the change is initiated via ethtool. The two users of netdev_compute_features have been converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

If the SHUTDOWN chunk can acknowledge all of the send DATA chunks, SHUTDOWN-ACK should be sent. But now endpoint just silently discarded the SHUTDOWN chunk. SHUTDOWN received in SHUTDOWN-PENDING state can happend when the last SACK is lost by network, or the SHUTDOWN chunk can acknowledge all of the received DATA chunks. The packet sequence(SACK lost) is like this: Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED) <----------- DATA <--- shutdown Enter SHUTDOWN-PENDING state SACK ----lost----> SHUTDOWN(*1) ------------> <----------- SHUTDOWN-ACK (*1) silently discarded now.

This is because the new l2t_entry.arpq skb queue is never initialized, and therefore trying to add an skb to it causes a NULL dereference. With the old code there was no need to initialize the queues because the l2t_entry structures were zeroed, and the code used NULL to mean empty.

| * | tcp: should use number of sack blocks instead of -1Ilpo Järvinen2008-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While looking for the recent "sack issue" I also read all eff_sacks usage that was played around by some relevant commit. I found out that there's another thing that is asking for a fix (unrelated to the "sack issue" though). This feature has probably very little significance in practice. Opposite direction timeout with bidirectional tcp comes to me as the most likely scenario though there might be other cases as well related to non-data segments we send (e.g., response to the opposite direction segment). Also some ACK losses or option space wasted for other purposes is necessary to prevent the earlier SACK feedback getting to the sender.

However there is a missing break statement for the _FP_CLS_COMBINE(FP_CLS_INF,FP_CLS_INF) switch case, the code just falls into _FP_CLS_COMBINE(FP_CLS_ZERO,FP_CLS_ZERO) which then proceeds to overwrite all of the settings. Fix by adding the missing break. Signed-off-by: David S. Miller <davem@davemloft.net>

In doing so I've been using TestFloat to see how good or bad we are doing. For the most part the current math-emu code that PPC uses has a number of issues that the code in include/math-emu seems to solve (plus bugs we've had for ever that no one every realized). Anyways, I've come across a case that we are flagging underflow and inexact because we think we have a denormalized result from a double precision divide: 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE soft: 001.0000000000000 ..... syst: 001.0000000000000 ...ux What it looks like is the results out of FP_DIV_D are: D: sign: 0 mantissa: 01000000 00000000 exp: -1023 (0) The problem seems like we aren't normalizing the result and bumping the exp. Now that I'm digging into this a bit I'm thinking my issue has to do with the fix DaveM put in place from back in Aug 2007 (commit 405849610fd96b4f34cd1875c4c033228fea6c0f): [MATH-EMU]: Fix underflow exception reporting. 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too ... Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. Here is the distilled glibc test case from Jakub Jelinek which prompted that commit: -------------------- #include <float.h> #include <fenv.h> #include <stdio.h> volatile double d = DBL_MIN; volatile double e = 0x0.0000000000001p-1022; volatile double f = 16.0; int main (void) { printf ("%x\n", fetestexcept (FE_UNDERFLOW)); d /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); e /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); return 0; } -------------------- It looks like the case I have we are exact before rounding, but think it looks like the rounding case since it appears as if "overflow is set". 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE = 001.0000000000000 I think the following adds the check for my case and still works for the issue your commit was trying to resolve.
