* [IPV4] devinet: show all addresses assigned to interfaceStephen Hemminger2007-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* [NET]: Do not dereference iov if length is zeroHerbert Xu2007-09-111-0/+3
| | | | | | | | | | | | When msg_iovlen is zero we shouldn't try to dereference msg_iov. 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.

* [TG3]: Workaround MSI bug on 5714/5780.Michael Chan2007-09-111-2/+11
| | | | | | | | | | | | | | | | | | | | A hardware bug was revealed after a recent PCI MSI patch was made to always disable legacy INTX when enabling MSI. The 5714/5780 chips will not generate MSI when INTX is disabled, causing MSI failure messages to be reported, and another patch was made to workaround the problem by disabling MSI on ServerWorks HT1000 bridge chips commonly found with the 5714. We workaround this chip bug by enabling INTX after we enable MSI and after we resume from suspend. Update version to 3.81. This problem was discovered by David Miller.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix "lost" interrupt problem when using dma with CD/DVD drives in some configurations. This problem can make installing linux from media impossible for distro's that have switched to libata-only configurations. The simple fix is to eliminate the use of dma for reading drive status, etc, by checking the number of bytes to transferred. This change will only affect the behavior of atapi devices, not disks.

* | i386: Fix perfctr watchdog on core duoStephane Eranian2007-09-111-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the NMI watchdog on Intel CoreDuo processor where the kernel would get stuck during boot. The issue is related to errata AE49, where the PERFEVTSEL1 counter does not have a working enable bit. Thus it is not possible to use it for NMI. The patch creates a dedicated wd_ops for CoreDuo which falls back to using PERFEVTSEL0. The other Intel processors supporting the architectural PMU will keep on using PERFEVTSEL1 as this allows other subsystems, such as perfmon, to use PERFEVTSEL0 for PEBS monitoring in particular.

* | Fix spurious syscall tracing after PTRACE_DETACH + PTRACE_ATTACHRoland McGrath2007-09-114-3/+1
|/ | | | | | | | | | | | | | | | | | | | | | When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This means that when a new tracer comes along and does PTRACE_ATTACH, it's possible he gets a syscall tracing stop even though he's never used PTRACE_SYSCALL. This happens if the task was in the middle of a system call when the second PTRACE_ATTACH was done. The symptom is an unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have been provoked by his ptrace calls so far. A few machines already fixed this in ptrace_disable (i386, ia64, m68k). But all other machines do not, and still have this bug. On x86_64, this constitutes a regression in IA32 compatibility support. Since all machines now use TIF_SYSCALL_TRACE for this, I put the clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather than adding it to every other machine's ptrace_disable.

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.

| * | m32r: Exit ei_handler directly for no IRQ case or IPI operationsHirokazu Takata2007-09-031-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no IRQ request is found in the IRQ check of ei_handler, we can exit directly by jumping "restore_all", instead of via "ret_from_intr". This modification is also likely effective for IPI operations, because scheduler call never happen at the exit of IPIs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify and clean up messy ei_handler code in arch/m32r/kernel/entry.S. - Remove ifdef's for CONFIG_CHIP_* configulations. - Rearrange the M32700 workaround code. - Remove the messy platform-dependent interrupt check routines and consolidate them to common INT0/INT1/INT2 check routines for all platforms with cascaded interrupt controllers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some m32r platforms, cascaded ICUs are used.
