14 years agoRevert mount/umount uevent removal
Greg Kroah-Hartman [Wed, 22 Feb 2006 17:39:02 +0000]
Revert mount/umount uevent removal

This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit
from Kay Sievers that removed the mount/umount uevents from the kernel.
Some older versions of HAL still depend on these events to detect when a
new device has been mounted.  These events are not correctly emitted,
and are broken by design, and so, should not be relied upon by any
future program.  Instead, the /proc/mounts file should be polled to
properly detect this kind of event.

A feature-removal-schedule.txt entry has been added, noting when this
interface will be removed from the kernel.

14 years ago[PATCH] tmpfs: fix mount mpol nodelist parsing
Hugh Dickins [Tue, 21 Feb 2006 23:49:47 +0000]
[PATCH] tmpfs: fix mount mpol nodelist parsing

I've been dissatisfied with the mpol_nodelist mount option which was
added to tmpfs earlier in -rc.  Replace it by mpol=policy:nodelist.

And it was broken: a nodelist is a comma-separated list of numbers and
ranges; the mount options are a comma-separated list of token=values.
Whoops, blindly strsep'ing on commas doesn't work so well: since we've
no numeric tokens, and unlikely to add them, use that to distinguish.

Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject
all its options as invalid if not NUMA.  /proc shows MPOL_PREFERRED
as "prefer", so use that name for the policy instead of "preferred".

Enforce that mpol=default has no nodelist; that mpol=prefer has one
node only; that mpol=bind has a nodelist; but let mpol=interleave use
node_online_map if no nodelist given.  Describe this in tmpfs.txt.

Hirokazu Takata [Tue, 21 Feb 2006 02:28:17 +0000]
[PATCH] m32r: update sys_tas() routine

This patch updates and fixes sys_tas() routine for m32r.

In the previous implementation, a lockup rarely caused at sys_tas()
routine in SMP environment.

> > The problem is that touching *addr will generate an oops if that page isn't
> > paged in.  If we convert it to use get_user() then that's an improvement,
> > but we must not run get_user() under spinlock or local_irq_disable().

I rewrote sys_tas() routine by using "lock -> unlock" instructions, and
utilizing the m32r's interrupt handling characteristics; the m32r processor
can accept interrupts only at the 32-bit instruction boundary.  So, the
"unlock" instruction can be executed continuously after the "lock"
instruction execution without any interruptions.

In addition, to solve such a page_fault problem, I use a fixup code like
get_user().

And, as for the kernel lockup problem, we found that a calling
do_page_fault() routine with disabling interrupts might cause a lockup at
flush_tlb_others(), because we checked a completion of IPI handler's
operations in a spin-locked critical section.

Therefore, by using "lock -> unlock" code, we can implement the sys_tas()
rouitine without disabling interrupts explicitly, then no lockups would
happen at flush_tlb_others(), I hope.

Compile check and some working test in SMP environment have done.

14 years ago[PATCH] Terminate process that fails on a constrained allocation
Christoph Lameter [Tue, 21 Feb 2006 02:27:52 +0000]
[PATCH] Terminate process that fails on a constrained allocation

Some allocations are restricted to a limited set of nodes (due to memory
policies or cpuset constraints).  If the page allocator is not able to find
enough memory then that does not mean that overall system memory is low.

In particular going postal and more or less randomly shooting at processes
is not likely going to help the situation but may just lead to suicide (the
whole system coming down).

It is better to signal to the process that no memory exists given the
constraints that the process (or the configuration of the process) has
placed on the allocation behavior.  The process may be killed but then the
sysadmin or developer can investigate the situation.  The solution is
similar to what we do when running out of hugepages.

This patch adds a check before we kill processes.  At that point
performance considerations do not matter much so we just scan the zonelist
and reconstruct a list of nodes.  If the list of nodes does not contain all
online nodes then this is a constrained allocation and we should kill the
current process.

14 years ago[PATCH] OOM kill: children accounting
Kurt Garloff [Tue, 21 Feb 2006 02:27:51 +0000]
[PATCH] OOM kill: children accounting

In the badness() calculation, there's currently this piece of code:

        /*
         * Processes which fork a lot of child processes are likely
         * a good choice. We add the vmsize of the children if they
         * have an own mm. This prevents forking servers to flood the
         * machine with an endless amount of children
         */
        list_for_each(tsk, &p->children) {
                struct task_struct *chld;
                chld = list_entry(tsk, struct task_struct, sibling);
                if (chld->mm = p->mm && chld->mm)
                        points += chld->mm->total_vm;
        }

The intention is clear: If some server (apache) keeps spawning new children
and we run OOM, we want to kill the father rather than picking a child.

This -- to some degree -- also helps a bit with getting fork bombs under
control, though I'd consider this a desirable side-effect rather than a
feature.

There's one problem with this: No matter how many or few children there are,
if just one of them misbehaves, and all others (including the father) do
everything right, we still always kill the whole family.  This hits in real
life; whether it's javascript in konqueror resulting in kdeinit (and thus the
whole KDE session) being hit or just a classical server that spawns children.

Sidenote: The killer does kill all direct children as well, not only the
selected father, see oom_kill_process().

The idea in attached patch is that we do want to account the memory
consumption of the (direct) children to the father -- however not fully.
This maintains the property that fathers with too many children will still
very likely be picked, whereas a single misbehaving child has the chance to
be picked by the OOM killer.

In the patch I account only half (rounded up) of the children's vm_size to
the parent.  This means that if one child eats more mem than the rest of
the family, it will be picked, otherwise it's still the father and thus the
whole family that gets selected.

This is heuristics -- we could debate whether accounting for a fourth would
be better than for half of it.  Or -- if people would consider it worth the
trouble -- make it a sysctl.  For now I sticked to accounting for half,
which should IMHO be a significant improvement.

The patch does one more thing: As users tend to be irritated by the choice
of killed processes (mainly because the children are killed first, despite
some of them having a very low OOM score), I added some more output: The
selected (father) process will be reported first and it's oom_score printed
to syslog.

Description:

Only account for half of children's vm size in oom score calculation

This should still give the parent enough point in case of fork bombs.  If
any child however has more than 50% of the vm size of all children
together, it'll get a higher score and be elected.

This patch also makes the kernel display the oom_score.

[IRDA]: irda-usb bug fixes

This patch fixes 2 bugs in the USB-IrDA code.

The first one is a buffer overrun in the RX path. We are now using
IRDA_SKB_MAX_MTU when initializing the Rx URB.

The second one is a potential stack recursion when unplugging the USB
dongle.  It seems that first we get the Rx URB with a generic error
code, and after a while the Rx URB comes again with a "disconnect"
error code.  Since we are resubmitting the Rx URB immediately after
receiving the first error one, we might enter an endless loop.

When getting an error Rx URB, the patch defers the Rx URB resubmitting
so that it gives us a chance to catch the disconnect one, in case the
dongle has juts been unplugged.

Tested against 2.6.16-rc2.

[PATCH] powerpc: Fix bug in spinup of renumbered secondary threads

If the logical and physical cpu ids of a secondary thread don't match, we will
fail to spin the thread up on pSeries machines due to a bug in pseries/smp.c

We call the RTAS "start-cpu" method with the physical cpu id, the address of
pSeries_secondary_smp_init and the value to pass that function in r3. Currently
we pass "lcpu", the logical cpu id, but pSeries_secondary_smp_init expects
the physical cpu id in r3.

We should be passing pcpu instead.

[PATCH] powerpc: Don't start secondary CPUs in a UP && KEXEC kernel

Because smp_release_cpus() is built for SMP || KEXEC, it's not safe to

Paul Mackerras [Sun, 19 Feb 2006 23:38:56 +0000]
powerpc: Keep xtime and gettimeofday in sync

This fixes a regression which was introduced by moving ppc32 to use
the same sort of lockless gettimeofday as ppc64 has been using for
some time.  This involves getting the timebase and performing some
simple arithmetic to convert it to seconds and microseconds.  However,
the factor and offset used there weren't being updated when NTP
varied the tick length using adjtimex.  64-bit didn't notice the
problem because it had a hook in the 32-bit adjtimex compat routine
that attempted to work out what the generic timekeeping code would
do and alter the factor and offset to match.  However, that code
was very complex and it wasn't clear that it still matched what the
generic code would do.

Now we use the generic current_tick_length() routine that was recently
added to check that the current tick will be as long as we expect; if
not we recompute the factor and offset.  This keeps gettimeofday and
xtime in sync.  In addition we check that gettimeofday hasn't got ahead
of xtime on each timer interrupt; if it has, we resync.

  The boot sequence on s390 sometimes takes ages and we spend a very long
  time (up to one or two minutes) in calibrate_migration_costs.  The time
  spent there differs from boot to boot.  Also the calculated costs differ
  a lot.  I've seen differences by up to a factor of 15 (yes, factor not
  percent).  Also I doubt that making these measurements make much sense on
  a completely virtualized architecture where you cannot tell how much cpu
  time you will get anyway.

So introduce the CONFIG_DEFAULT_MIGRATION_COST method for an architecture
to set the scheduler migration costs.  This turns off automatic detection
of migration costs.  Makes sense on virtual platforms, where migration

14 years ago[PATCH] fix deadlock in ext2
Peter Staubach [Fri, 17 Feb 2006 21:52:36 +0000]
[PATCH] fix deadlock in ext2

Fix a deadlock possible in the ext2 file system implementation.  This
deadlock occurs when a file is removed from an ext2 file system which was
mounted with the "sync" mount option.

The problem is that ext2_xattr_delete_inode() was invoking the routine,
sync_dirty_buffer(), using a buffer head which was previously locked via
lock_buffer().  The first thing that sync_dirty_buffer() does is to lock
the buffer head that it was passed.  It does this via lock_buffer().  Oops.

The solution is to unlock the buffer head in ext2_xattr_delete_inode()
before invoking sync_dirty_buffer().  This makes the code in
ext2_xattr_delete_inode() obey the same locking rules as all other callers
of sync_dirty_buffer() in the ext2 file system implementation.
