changeset 48611c47 in mainline. When only GSO skb was partially ACKed, no hints are reset, therefore fastpath_cnt_hint must be tweaked too or else it can corrupt fackets_out. The corruption to occur, one must have non-trivial ACK/SACK sequence, so this bug is not very often that harmful. There's a fackets_out state reset in TCP because fackets_out is known to be inaccurate and that fixes the issue eventually anyway. In case there was also at least one skb that got fully ACKed, the fastpath_skb_hint is set to NULL which causes a recount for fastpath_cnt_hint (the old value won't be accessed anymore), thus it can safely be decremented without additional checking.

changeset 6536a6b331d3225921c398eb7c6e4ecedb9b05e0 from mainline Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

changeset e79ad711 from mainline. This fixes kernel bugzilla #5731 It should generate an empty packet for datagram protocols when the socket is connected, for one. The check is doubly-wrong because all that a write() can be is a sendmsg() call with a NULL msg_control and a single entry iovec. No special semantics should be assigned to it, therefore the zero length check should be removed entirely. This matches the behavior of BSD and several other systems. Alan Cox notes that SuSv3 says the behavior of a zero length write on non-files is "unspecified", but that's kind of useless since BSD has defined this behavior for a quarter century and BSD is essentially what application folks code to. Based upon a patch from Stephen Hemminger. Signed-off-by:

changeset bf0b48df from mainline. When the ICMPv6 Target address is multicast, Linux processes the redirect instead of dropping it. The problem is in this code in ndisc_redirect_rcv(): if (ipv6_addr_equal(dest, target)) { on_link = 1; } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) { ND_PRINTK2(KERN_WARNING "ICMPv6 Redirect: target address is not link-local.\n"); return; } This second check will succeed if the Target address is, for example, FF02::1 because it has link-local scope. Instead, it should be checking if it's a unicast link-local address, as stated in RFC 2461/4861 Section 8.1: - The ICMP Target Address is either a link-local address (when redirected to a router) or the same as the ICMP Destination Address (when redirected to the on-link destination). I know this doesn't explicitly say unicast link-local address, but it's implied. This bug is preventing Linux kernels from achieving IPv6 Logo Phase II certification because of a recent error that was found in the TAHI test suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the multicast address in the Destination field instead of Target field, so we were passing the test. This won't be the case anymore. The patch below fixes this problem, and also fixes ndisc_send_redirect() to not send an invalid redirect with a multicast address in the Target field. I re-ran the TAHI Neighbor Discovery section to make sure Linux passes all 245 tests now. Signed-off-by:

changeset b04e7bdb from mainline. device_suspend() calls ACPI suspend functions, which seems to have undesired side effects on lower idle C-states. It took me some time to realize that especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one) show this effect. I'm quite sure that other bug reports against suspend/resume about turning the system into a brick have the same root cause. After fishing in the dark for quite some time, I realized that removing the ACPI processor module before suspend (this removes the lower C-state functionality) made the problem disappear. Interestingly enough the propability of having a bricked box is influenced by various factors (interrupts, size of the ram image, ...). Even adding a bunch of printks in the wrong places made the problem go away. The previous periodic tick implementation simply pampered over the problem, which explains why the dyntick / clockevents changes made this more prominent. We avoid complex functionality during the boot process and we have to do the same during suspend/resume. It is a similar scenario and equaly fragile. Add suspend / resume functions to the ACPI processor code and disable the lower idle C-states across suspend/resume. Fall back to the default idle implementation (halt) instead. Signed-off-by:

commit d3f7eae1 upstream The Averatec 2370 and some other Turion laptop BIOS seems to program the ENABLE_C1E MSR inconsistently between cores. This confuses the lapic use heuristics because when C1E is enabled anywhere it seems to affect the complete chip. Use a global flag instead of a per cpu flag to handle this. If any CPU has C1E enabled disabled lapic use. Thanks to Cal Peake for debugging. Cc: tglx@linutronix.de Cc: Chuck Ebbert <cebbert@redhat.com> Signed-off-by:

Sometimes the integer part was incorrect due to rounding (we werent taking the fractional seconds into consideration). The fraction part is also wrong, we need to pad the printf statement and take the bottom three digits of 1000 times the value. Signed-off-by:

commit 255129d1 in upstream. The problem is that the garbage collector for the 'host' structures nlm_gc_hosts(), holds nlm_host_mutex while calling down to nlmsvc_mark_resources, which, eventually takes the file->f_mutex. We cannot therefore call nlmsvc_lookup_host() from within nlmsvc_create_block, since the caller will already hold file->f_mutex, so the attempt to grab nlm_host_mutex may deadlock. Fix the problem by calling nlmsvc_lookup_host() outside the file->f_mutex. Signed-off-by:

In Linus tree already: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=939bc4943d0483961edc45b63a7d27b4ffe547e3 This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN, used to implement i2c_smbus_read_block_data(). Previously, in the absence of PEC (rarely used!) it would NAK the "length" byte: S addr Rd [A] [length] NA That prevents the subsequent data bytes from being read: S addr Rd [A] [length] { A [data] }* NA The primary fix just reorders two code blocks, so the length used in the "should I NAK now?" check incorporates the data which it just read from the slave device. However, that move also highlighted other fault handling glitches. This fixes those by abstracting the RX path ack/nak logic, so it can be used in more than one location. Signed-off-by:

commit 2302827c from upstream Domain Validation in the SPI transport class is failing on boxes with damaged cables (and failing to the extent that the box hangs). The problem is that the first test it does is a cable integrity test for wide transfers and if this fails, it turns the wide bit off. The problem is that the next set of tests it does turns wide back on again, with the result that it runs through the entirety of DV with a known bad setting and then hangs the system. The attached patch fixes the problem by physically nailing the wide setting to what it deduces it should be for the whole of Domain Validation. Signed-off-by:

port of 3f708697 from mainline. A crash upon booting that is caused by bcm43xx has been reported [1] and found to be due to a work queue being reinitialized while work on that queue is still pending. This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced. [1] http://bugzilla.kernel.org/show_bug.cgi?id=8937Signed-off-by:

Right now the only thing that tries to do so is skb_copy_and_csum_datagram_iovec. Since the total length should also be zero if msg_iovlen is zero, it's sufficient to check the total length there and simply return if it's zero. Signed-off-by:

commit 8c7b43a2e58baa24002fa2b266d9a5007bc52a40 in mainline I tried to preserve bridging code as it was before, but logic is quite strange - I think we should free skb on error, since it is already unshared and thus will just leak. Herbert Xu states: > + if ((skb = skb_share_check(skb, GFP_ATOMIC)) == NULL) > + goto out; If this happens it'll be a double-free on skb since we'll return NF_DROP which makes the caller free it too. We could return NF_STOLEN to prevent that but I'm not sure whether that's correct netfilter semantics. Patrick, could you please make a call on this? Patrick McHardy states: NF_STOLEN should work fine here. Signed-off-by:

commit 8ee4f391831cb96916a8e8a05f04b1c1d7dd30d8 in mainline. In testing our ESP/AH offload hardware, I discovered an issue with how AH handles mutable fields in IPv4. RFC 4302 (AH) states the following on the subject: For IPv4, the entire option is viewed as a unit; so even though the type and length fields within most options are immutable in transit, if an option is classified as mutable, the entire option is zeroed for ICV computation purposes. The current implementation does not zero the type and length fields, resulting in authentication failures when communicating with hosts that do (i.e. FreeBSD). I have tested record route and timestamp options (ping -R and ping -T) on a small network involving Windows XP, FreeBSD 6.2, and Linux hosts, with one router. In the presence of these options, the FreeBSD and Linux hosts (with the patch or with the hardware) can communicate. The Windows XP host simply fails to accept these packets with or without the patch. I have also been trying to test source routing options (using traceroute -g), but haven't had much luck getting this option to work *without* AH, let alone with.

commit e1f52208 in mainline. [IPv6]: Fix NULL pointer dereference in ip6_flush_pending_frames Some of skbs in sk->write_queue do not have skb->dst because we do not fill skb->dst when we allocate new skb in append_data(). BTW, I think we may not need to (or we should not) increment some stats when using corking; if 100 sendmsg() (with MSG_MORE) result in 2 packets, how many should we increment? If 100, we should set skb->dst for every queued skbs. If 1 (or 2 (*)), we increment the stats for the first queued skb and we should just skip incrementing OutDiscards for the rest of queued skbs, adn we should also impelement this semantics in other places; e.g., we should increment other stats just once, not 100 times. *: depends on the place we are discarding the datagram. I guess should just increment by 1 (or 2). Signed-off-by:

commit 596e4150 in mainline Bug: http://bugzilla.kernel.org/show_bug.cgi?id=8876 Not all ips are shown by "ip addr show" command when IPs number assigned to an interface is more than 60-80 (in fact it depends on broadcast/label etc presence on each address). Steps to reproduce: It's terribly simple to reproduce: # for i in $(seq 1 100); do ip ad add 10.0.$i.1/24 dev eth10 ; done # ip addr show this will _not_ show all IPs. Looks like the problem is in netlink/ipv4 message processing. This is fix from bug submitter, it looks correct. Signed-off-by:
