2008-01-15[POWERPC] Fix boot failure on POWER6Paul Mackerras3-10/+2
Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.

This reverts commit 2e6883bdf49abd0e7f0d9b6297fc3be7ebb2250b, as requested by Fengguang Wu. It's not quite fully baked yet, and while there are patches around to fix the problems it caused, they should get more testing. Says Fengguang: "I'll resend them both for -mm later on, in a more complete patchset". See http://bugzilla.kernel.org/show_bug.cgi?id=9738 for some of this discussion.

2008-01-15[POWERPC] Workaround for iommu page alignmentBenjamin Herrenschmidt1-3/+14
Commit 5d2efba64b231a1733c4048d1708d77e07f26426 changed our iommu code so that it always uses an iommu page size of 4kB. That means with our current code, drivers may do a dma_map_sg() of a 64kB page and obtain a dma_addr_t that is only 4k aligned. This works fine in most cases except for some infiniband HW it seems, where they tell the HW about the page size and it ignores the low bits of the DMA address. This works around it by making our IOMMU code enforce a PAGE_SIZE alignment for mappings of objects that are page aligned in the first place and whose size is larger or equal to a page.

2008-01-14sata_sil24: freeze on non-dev errors reported via CERRTejun Heo1-0/+3
CERR reports errors detected during executing a command. This doesn't mean the error is tied to the command and can be recovered by just issuing it again. Many of the errors are fatal port-wide connditions including HSM violation, host bus error and ATA bus error and require freezing and port reset. The freezing part wasn't implemented previously. This used to be okay because port resets were scheduled anyway and EH eventually resets and recovers the port. With PMP support added, this is no longer true. The error condition and recover actions are attributed to the fan-out port and the host port condition isn't properly recovered leading to EH failures. This patch makes CERR errors which require resets to freeze the port. This will force host port reset and proper recovery.

Commit 84427eaef1fb91704c7112bdb598c810003b99f3 (remove task_ppid_nr_ns) moved the task_tgid_nr_ns(task->real_parent) outside of lock_task_sighand(). This is wrong, ->real_parent could be freed/reused. Both ->parent/real_parent point to nothing after __exit_signal() because we remove the child from ->children list, and thus the child can't be reparented when its parent exits. rcu_read_lock() protects ->parent/real_parent, but _only_ if we know it was valid before we take rcu lock.

2008-01-14Kick CPUS that might be sleeping in cpus_idle_waitSteven Rostedt2-0/+22
Sometimes cpu_idle_wait gets stuck because it might miss CPUS that are already in idle, have no tasks waiting to run and have no interrupts going to them. This is common on bootup when switching cpu idle governors. This patch gives those CPUS that don't check in an IPI kick. Background: ----------- I notice this while developing the mcount patches, that every once in a while the system would hang. Looking deeper, the hang was always at boot up when registering init_menu of the cpu_idle menu governor. Talking with Thomas Gliexner, we discovered that one of the CPUS had no timer events scheduled for it and it was in idle (running with NO_HZ). So the CPU would not set the cpu_idle_state bit. Hitting sysrq-t a few times would eventually route the interrupt to the stuck CPU and the system would continue. Note, I would have used the PDA isidle but that is set after the cpu_idle_state bit is cleared, and would leave a window open where we may miss being kicked. hmm, looking closer at this, we still have a small race window between clearing the cpu_idle_state and disabling interrupts (hence the RFC). CPU0: CPU 1: --------- --------- cpu_idle_wait(): cpu_idle(): | __cpu_cpu_var(is_idle) = 1; | if (__get_cpu_var(cpu_idle_state)) /* == 0 */ per_cpu(cpu_idle_state, 1) = 1; | if (per_cpu(is_idle, 1)) /* == 1 */ | smp_call_function(1) | | receives ipi and runs do_nothing. wait on map == empty idle(); /* waits forever */ So really we need interrupts off for most of this then. One might think that we could simply clear the cpu_idle_state from do_nothing, but I'm assuming that cpu_idle governors can be removed, and this might cause a race that a governor might be used after the module was removed. Venki said: I think your RFC patch is the right solution here. As I see it, there is no race with your RFC patch. As long as you call a dummy smp_call_function on all CPUs, we should be OK. We can get rid of cpu_idle_state and the current wait forever logic altogether with dummy smp_call_function. And so there wont be any wait forever scenario. The whole point of cpu_idle_wait() is to make all CPUs come out of idle loop atleast once. The caller will use cpu_idle_wait something like this. // Want to change idle handler - Switch global idle handler to always present default_idle - call cpu_idle_wait so that all cpus come out of idle for an instant and stop using old idle pointer and start using default idle - Change the idle handler to a new handler - optional cpu_idle_wait if you want all cpus to start using the new handler immediately. Maybe the below 1s patch is safe bet for .24. But for .25, I would say we just replace all complicated logic by simple dummy smp_call_function and remove cpu_idle_state altogether.

2008-01-13knfsd: Allow NFSv2/3 WRITE calls to succeed when krb5i etc is used.NeilBrown2-2/+8
When RPCSEC/GSS and krb5i is used, requests are padded, typically to a multiple of 8 bytes. This can make the request look slightly longer than it really is. As of f34b95689d2ce001c "The NFSv2/NFSv3 server does not handle zero length WRITE request correctly", the xdr decode routines for NFSv2 and NFSv3 reject requests that aren't the right length, so krb5i (for example) WRITE requests can get lost. This patch relaxes the appropriate test and enhances the related comment. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: J.

2008-01-13remove task_ppid_nr_nsRoland McGrath3-16/+3
task_ppid_nr_ns is called in three places. One of these should never have called it. In the other two, using it broke the existing semantics. This was presumably accidental. If the function had not been there, it would have been much more obvious to the eye that those patches were changing the behavior. We don't need this function. In task_state, the pid of the ptracer is not the ppid of the ptracer. In do_task_stat, ppid is the tgid of the real_parent, not its pid. I also moved the call outside of lock_task_sighand, since it doesn't need it. In sys_getppid, ppid is the tgid of the real_parent, not its pid.
