Denys Fedoryshchenko reported a bootup crash when he upgraded
his system from 3GB to 4GB RAM:
http://lkml.org/lkml/2008/1/7/9
the bug is due to HIGHMEM4G && SPARSEMEM kernels making pfn_to_page()
to return an invalid pointer when the pfn is in a memory hole. The
256 MB PCI aperture at the end of RAM was not mapped by sparsemem,
and hence the pfn was not valid. But set_highmem_pages_init() iterated
this range without checking the pfn's validity first.
this bug was probably present in the sparsemem code ever since sparsemem
has been introduced in v2.6.13. It was masked due to HIGHMEM64G using
larger memory regions in sparsemem_32.h:
#ifdef CONFIG_X86_PAE
#define SECTION_SIZE_BITS 30
#define MAX_PHYSADDR_BITS 36
#define MAX_PHYSMEM_BITS 36
#else
#define SECTION_SIZE_BITS 26
#define MAX_PHYSADDR_BITS 32
#define MAX_PHYSMEM_BITS 32
#endif
which creates 1GB sparsemem regions instead of 64MB sparsemem regions.
So in practice we only ever created true sparsemem holes on x86 with
HIGHMEM4G - but that was rarely used by distros.
( btw., we could probably save 2MB of mem_map[]s on X86_PAE if we reduced
the sparsemem region size to 256 MB. )

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

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.

The patch below fixes two problems for Kconfig on the BCM47xx platform:
- arch/mips/bcm47xx/gpio.c uses ssb_extif_* functions. Selecting
SSB_DRIVER_EXTIF makes sure those functions are available.
- arch/mips/pci/pci.c needs, when enabled, platform specific functions,
which are defined when SSB_PCICORE_HOSTMODE is enabled.

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.
Revert this part of the patch.

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.

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.

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.

pnpacpi: exceeded the max number of IO resources: 40
While this message is a real error and should thus
remain KERN_ERR (even a new dmesg line is seen as a regression
by some, since it was not printed in 2.6.23...) it is certainly
impolite to print this warning 50 times should you happen to
have the oddball system with 90 io resources under a device...
So print the warning just once.
In 2.6.25 we'll get rid of the limits altogether
and these warnings will vanish with them.

Way back when (in commit 834f2a4a1554dc5b2598038b3fe8703defcbe467, aka
"VFS: Allow the filesystem to return a full file pointer on open intent"
to be exact), Trond changed the open logic to keep track of the original
flags to a file open, in order to pass down the the intent of a dentry
lookup to the low-level filesystem.
However, when doing that reorganization, it changed the meaning of
namei_flags, and thus inadvertently changed the test of access mode for
directories (and RO filesystem) to use the wrong flag. So fix those
