* [ICMP]: Fix icmp_errors_use_inbound_ifaddr sysctlPatrick McHardy2007-06-03
| | | | | | | | | | | | Currently when icmp_errors_use_inbound_ifaddr is set and an ICMP error is sent after the packet passed through ip_output(), an address from the outgoing interface is chosen as ICMP source address since skb->dev doesn't point to the incoming interface anymore. Fix this by doing an interface lookup on rt->dst.iif and using that device. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NET] gso: Fix GSO feature mask in sk_setup_capsHerbert Xu2007-06-03
| | | | | | | | | | | | | | | | This isn't a bug just yet as only TCP uses sk_setup_caps for GSO. However, if and when UDP or something else starts using it this is likely to cause a problem if we forget to add software emulation for it at the same time. The problem is that right now we translate GSO emulation to the bitmask NETIF_F_GSO_MASK, which includes every protocol, even ones that we cannot emulate. This patch makes it provide only the ones that we can emulate. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP]: Fix GSO ignorance of pkts_acked arg (cong.cntrl modules)Ilpo Järvinen2007-06-03
| | | | | | | | | | | | The code used to ignore GSO completely, passing either way too small or zero pkts_acked when GSO skb or part of it got ACKed. In addition, there is no need to calculate the value in the loop but simple arithmetics after the loop is sufficient. There is no need to handle SYN case specially because congestion control modules are not yet initialized when FLAG_SYN_ACKED is set.

* [ATM]: Fix warning.Jeff Garzik2007-06-03
| | | | | | | | | | | | | | | | | | The compiler warning drivers/atm/firestream.c: In function ‘top_off_fp’: drivers/atm/firestream.c:1505: warning: cast to pointer from integer of different size does indicate a bug, albeit a minor one. Fixed, by using a 32-bit temporary prior to the call to bus_to_virt(). The larger bug is still present: the entire driver assumes that machine pointers are 32-bit, as it stores pointers in 32-bit hardware registers. This is obvious to anyone who knows the driver well, but for the casual readers it is helpfully noted with FIXME. Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

* [TCP]: Use default 32768-61000 outgoing port range in all cases.Mark Glines2007-06-03
| | | | | | | | | | | | | | This diff changes the default port range used for outgoing connections, from "use 32768-61000 in most cases, but use N-4999 on small boxes (where N is a multiple of 1024, depending on just *how* small the box is)" to just "use 32768-61000 in all cases". I don't believe there are any drawbacks to this change, and it keeps outgoing connection ports farther away from the mess of IANA-registered ports.

* [AF_UNIX]: Fix datagram connect race causing an OOPS.David S. Miller2007-06-03
| | | | | | | | | | | | | | | | | | | | | | | | Based upon an excellent bug report and initial patch by Frederik Deweerdt. The UNIX datagram connect code blindly dereferences other->sk_socket via the call down to the security_unix_may_send() function. Without locking 'other' that pointer can go NULL via unix_release_sock() which does sock_orphan() which also marks the socket SOCK_DEAD. So we have to lock both 'sk' and 'other' yet avoid all kinds of potential deadlocks (connect to self is OK for datagram sockets and it is possible for two datagram sockets to perform a simultaneous connect to each other). So what we do is have a "double lock" function similar to how we handle this situation in other areas of the kernel. We take the lock of the socket pointer with the smallest address first in order to avoid ABBA style deadlocks. Once we have them both locked, we check to see if SOCK_DEAD is set for 'other' and if so, drop everything and retry the lookup. Signed-off-by: David S. Miller <davem@davemloft.net>
* [TG3]: Fix link problem on Dell's onboard 5906.Michael Chan2007-06-03
| | | | | | | | | | | | | | | | | | | The bug is caused by code that always set (TG3_FLAG_USE_MI_INTERRUPT | TG3_FLAG_USE_LINKCHG_REG) on all Dell's onboard devices. With these 2 flags set, the link status is polled by tg3_timer() and will only work when the PHY is set up to interrupt the MAC on link changes. This breaks 5906 because the 5906 PHY does not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs. For correctness, only Dell's onboard 5701 needs these 2 flags to be set. This change will fix the 5906 problem and will change other Dell devices except 5700 and 5701 to use the more efficient interrupt-driven link changes. Update version to 3.77.

There are also inb/outb definitions which are totally bogus (missing brackets in _both_ cases, SMC_CAN_USE_8BIT == 0, and even better, they try to use a 16-bit access to fake 8-bit access).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The interface for network device VLAN extension was confusing. The kill_vid function is only really useful for devices that do hardware filtering.

In particular, this makes the bootwrapper use -msoft-float, preventing the compiler from generating floating point instructions. Previously, under some circumstances the compiler could generate floating point instructions in the bootwrapper which would cause exceptions on embedded CPUS which don't have floating point support.

The common code expects tlb_flush() to actually flush any pending TLB batch. It does that because it delays all page freeing until after tlb_flush() is called, in order to ensure no stale reference to those pages exist in any TLB, thus causing potential access to the freed pages. However, our tlb_flush only triggers the RCU for freeing page table pages, it does not currently trigger a flush of a pending TLB/hash batch, which is, I think, an error. This fixes it.

As a result, it can do more damage than good because it causes the BIOS to follow un-tested paths. Recently, several machines have turned up that erroneously test this string in a way which causes them to _not_ test other compatibility strings, including the ZI9 and Toshiba. So it appears that this bad code has made it into a BIOS vendor's reference BIOS. Linux has no choice but to stop advertising compatibility with _OSI string "Linux" - as there are an unbounded number of possible incompatibilities going forward. But some BIOSes have already shipped which do use it for things like conditionally re-enabling video on resume from S3. (Too bad they didn't do that unconditionally) Add special case code for _OSI(Linux) Squawk to dmesg if _OSI(Linux) is requested Add DMI list both to enable and disable _OSI(Linux) But for now, keep the default enabled via #define OSI_LINUX_ENABLED. http://bugzilla.kernel.org/show_bug.cgi?id=7787 Signed-off-by: Len Brown <len.brown@intel.com>
| * | | ACPI: extend "acpi_osi=" boot optionLen Brown2007-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The boot option "acpi_osi=" has always disabled Linux _OSI support, thus disabling all OS Interface strings which are advertised by Linux to the BIOS. Now... acpi_osi="string" adds the interface string, and acpi_osi="!string" invalidates the pre-defined interface string eg. acpi_osi="!Windows 2006" would disable Linux's claim of Vista compatibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implemented support to allow Package objects to be passed as method arguments to the acpi_evaluate_object interface. Previously, this would return an AE_NOT_IMPLEMENTED exception. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
| * | | ACPI: Section mismatch ... acpi_map_pxm_to_nodeLuck, Tony2007-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Last of the "Section mismatch" errors from ia64 builds! acpi_map_pxm_to_node() is defined with attribute __cpuinit, but is called by "normal" kernel functions acpi_getnode() and acpi_map_cpu2node(). Commit f363d16fbb9374c0bd7f2757d412c287169094c9 moved the data structures on which this routine operates from __cpuinitdata to regular memory, so this routine can also move out of init space.

| * | | ACPI: thinkpad-acpi: do not use named sysfs groupsHenrique de Moraes Holschuh2007-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial version of the thinkpad-acpi sysfs interface (not yet released in any stable mainline kernel) made liberal use of named sysfs groups, in order to get the attributes more organized. This proved to be a really bad design decision. Maybe if attribute groups were as flexible as a real directory, and if binary attributes were not second-class citizens, the idea of subdirs and named groups would not have been so bad. This patch makes all the thinkpad-acpi sysfs groups anonymous (thus removing the subdirs), adds the former group names as a prefix (so that hotkey/enable becomes hotkey_enable for example), and updates the documentation. These changes will make the thinkpad-acpi sysfs ABI a lot easier to maintain. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
