13 years ago[IA64] make ioremap avoid unsupported attributes
Bjorn Helgaas [Fri, 30 Mar 2007 16:34:05 +0000]
[IA64] make ioremap avoid unsupported attributes

Example memory map (from HP sx1000 with VGA enabled):
    0x00000 - 0x9FFFF supports only WB (cacheable) access
    0xA0000 - 0xBFFFF supports only UC (uncacheable) access
    0xC0000 - 0xFFFFF supports only WB (cacheable) access

pci_read_rom() indirectly uses ioremap(0xC0000) to read the shadow VGA option
ROM.  ioremap() used to default to a 16MB or 64MB UC kernel identity mapping,
which would cause an MCA when reading 0xC0000 since only WB is supported there.

X uses reads the option ROM to initialize devices.  A smaller test case is:
  # echo 1 > /sys/bus/pci/devices/0000:aa:03.0/rom
  # cp /sys/bus/pci/devices/0000:aa:03.0/rom x

To avoid this, we can use the same ioremap_page_range() strategy that most
architectures use for all ioremaps.  These page table mappings come out of the
vmalloc area.  On ia64, these are in region 5 (0xA... addresses) and typically
use 16KB or 64KB mappings instead of 16MB or 64MB mappings.  The smaller
mappings give more flexibility to use the correct attributes.

[IA64] bugfix stack layout upside-down

ia64 expects following vm layout:

== low memory
[register-stack grows up]
[memory-stack grows down]
== high memory

But the code assigns the base of the register stack at the
maximum stack size offset from the fixed address where the
stack *might* start.  Stack randomization will result in the
memory stack starting at a lower address than this, and if the
user has set a low stack limit with "ulimit -s", then you can
end up with the register stack above the memory stack (or if
you were very unlucky right on top of it!).

Fix: Calculate the base address for the register stack starting
from the actual address of the memory stack.

13 years ago[PATCH] holepunch: fix disconnected pages after second truncate
Hugh Dickins [Thu, 29 Mar 2007 08:20:37 +0000]
[PATCH] holepunch: fix disconnected pages after second truncate

shmem_truncate_range has its own truncate_inode_pages_range, to free any pages
racily instantiated while it was in progress: a SHMEM_PAGEIN flag is set when
this might have happened.  But holepunching gets no chance to clear that flag
at the start of vmtruncate_range, so it's always set (unless a truncate came
just before), so holepunch almost always does this second
truncate_inode_pages_range.

shmem holepunch has unlikely swap<->file races hereabouts whatever we do
(without a fuller rework than is fit for this release): I was going to skip
the second truncate in the punch_hole case, but Miklos points out that would
make holepunch correctness more vulnerable to swapoff.  So keep the second
truncate, but follow it by an unmap_mapping_range to eliminate the
disconnected pages (freed from pagecache while still mapped in userspace) that
it might have left behind.

Hugh Dickins [Thu, 29 Mar 2007 08:20:36 +0000]
[PATCH] holepunch: fix shmem_truncate_range punch locking

Miklos Szeredi observes that during truncation of shmem page directories,
info->lock is released to improve latency (after lowering i_size and
next_index to exclude races); but this is quite wrong for holepunching, which
receives no such protection from i_size or next_index, and is left vulnerable
to races with shmem_unuse, shmem_getpage and shmem_writepage.

Hold info->lock throughout when holepunching?  No, any user could prevent
rescheduling for far too long.  Instead take info->lock just when needed: in
shmem_free_swp when removing the swap entries, and whenever removing a
directory page from the level above.  But so long as we remove before
scanning, we can safely skip taking the lock at the lower levels, except at
misaligned start and end of the hole.

Hugh Dickins [Thu, 29 Mar 2007 08:20:35 +0000]
[PATCH] holepunch: fix shmem_truncate_range punching too far

Miklos Szeredi observes BUG_ON(!entry) in shmem_writepage() triggered in rare
circumstances, because shmem_truncate_range() erroneously removes partially
truncated directory pages at the end of the range: later reclaim on pages
pointing to these removed directories triggers the BUG.  Indeed, and it can
also cause data loss beyond the hole.

Fix this as in the patch proposed by Miklos, but distinguish between "limit"
(how far we need to search: ignore truncation's next_index optimization in the
holepunch case - if there are races it's more consistent to act on the whole
range specified) and "upper_limit" (how far we can free directory pages:
generally we must be careful to keep partially punched pages, but can relax at
end of file - i_size being held stable by i_mutex).

Jason Lunz [Thu, 29 Mar 2007 08:20:31 +0000]
[PATCH] uml: fix LVM crash

Permit lvm to create logical volumes without crashing UML.

When device-mapper's DM_DEV_CREATE_CMD ioctl is called to create a new device,
dev_create()->dm_create()->alloc_dev()-> blk_queue_bounce_limit(md->queue,
BLK_BOUNCE_ANY) is called.

blk_queue_bounce_limit(BLK_BOUNCE_ANY) calls init_emergency_isa_pool() if
blk_max_pfn < blk_max_low_pfn.  This is the case on UML, but
init_emergency_isa_pool() hits BUG_ON(!isa_page_pool) because there doesn't
seem to be a dma zone on UML for mempool_create() to allocate from.

Most architectures seem to have max_low_pfn == max_pfn, but UML doesn't
because of the uml_reserved chunk it keeps for itself.  From what I can see,
max_pfn and max_low_pfn don't get much use after the bootmem-allocator stops
being used anyway, except that they initialize the block layer's
blk_max_low_pfn/blk_max_pfn.

This ensures init_emergency_isa_pool() doesn't crash uml in this situation by
setting max_low_pfn == max_pfn in mem_init().

[PATCH] uml: irq locking fixes

As the comment immediately preceding this points out, this list is changed in
irq context, so it needs to be protected with spin_lock_irqsave in process
context when it is processed.

Sometimes, gcc should just compile the comments and forget the code.

The IRQ side of this was better, in the sense that it blocked and unblocked
interrupts, but it still should have saved and restored them.

[PATCH] uml: fix I/O hang when multiple devices are in use

Commit 62f96cb01e8de7a5daee472e540f726db2801499 introduced per-devices
queues and locks, which was fine as far as it went, but left in place a
global which controlled access to submitting requests to the host.  This
should have been made per-device as well, since it causes I/O hangs when
multiple block devices are in use.

This patch fixes that by replacing the global with an activity flag in the
device structure in order to tell whether the queue is currently being run.

[PATCH] bluetooth hid quirks: mightymouse quirk

I have a bugreport that scrollwheel of bluetooth version of apple
mightymouse doesn't work.  The USB version of mightymouse works, as there
is a quirk for handling scrollwheel in hid/usbhid for it.

Now that bluetooth git tree is hooked to generic hid layer, it could easily
use the quirks which are already present in generic hid parser, hid-input,
etc.

Below is a simple patch against bluetooth git tree, which adds quirk
handling to current bluetooth hidp code, and sets quirk flags for device
0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

[PATCH] pid: Properly detect orphaned process groups in exit_notify

In commit 0475ac0845f9295bc5f69af45f58dff2c104c8d1 when converting the
orphaned process group handling to use struct pid I made a small
mistake.  I accidentally replaced an == with a !=.

Besides just being a dumb thing to do apparently this has a bad side
effect.  The improper orphaned process group detection causes kwin to
die after a suspend/resume cycle.

However a thorough cleanup is a little extreme for this point in the

irq when msi irq's are enabled should be the first fix.  Then we can
later make the code not change the irqs at all.

mv643xx_eth: Fix use of uninitialized port_num field

In this driver, the default ethernet address is first set by by calling
eth_port_uc_addr_get() which reads the relevant registers of the
corresponding port as initially set by firmware. However that function
used the port_num field accessed through the private area of net_dev
before it was set.

The result was that one board I have ended up with the unicast address
set to 00:00:00:00:00:00 (only port 1 is connected on this board). The
problem appeared after commit 84dd619e4dc3b0b1c40dafd98c90fd950bce7bc5.

This patch fixes the bug by setting mp->port_num prior to calling
eth_port_uc_get_addr().

[PATCH] Revert "swsusp: disable nonboot CPUs before entering platform suspend"

This reverts commit 94985134b7b46848267ed6b734320db01c974e72 and
insteads removes the WARN_ON() that caused that commit in the first
place.

The problem is that we call disable_nonboot_cpus() in swsusp before
powering down the system in order to avoid triggering the WARN_ON()
in arch/x86_64/kernel/acpi/sleep.c:init_low_mapping() and this doesn't
work well on Thomas' system.

So instead, remove the WARN_ON() in arch/x86_64/kernel/acpi/sleep.c:
init_low_mapping(), which triggers every time during the suspend to disk
in the platform mode, as the potential problem it is related to doesn't
seem to occur in practice.

[ I think we might want to disallow the case of multiple users of that
  mm, or something.  Normally, playing with the current process page
  tables on the current CPU should be fine as long as we don't have

All those functions are in fs/proc/proc_sysctl.c, which has no CONFIG_
#define's in it, so the patch makes the compilation of that file to depend
on CONFIG_PROC_SYSCTL (the simplest choice).

[PATCH] I2O: remove Markus from MAINTAINERS

Because i don't have much time lately and my responses are pretty slow
it's probably best to remove me from MAINTAINERS to give someone else
the chance to jump in.

[PATCH] ipcns: fix !CONFIG_IPC_NS behavior

When CONFIG_IPC_NS=n, clone(CLONE_NEWIPC) claims success, but did not actually
clone a new IPC namespace.

Fix this to return -EINVAL so the caller knows his request was denied.
