[PATCH] sd: initialize SD cards

Support for the Secure Digital protocol in the MMC layer.

A summary of the legal issues surrounding SD cards, as understood by yours
truly:

Members of the Secure Digital Association, hereafter SDA, are required to sign
a NDA[1] before given access to any specifications.  It has been speculated
that including an SD implementation would forbid these members to redistribute
Linux.  This is the basic problem with SD support so it is unclear if it even
is a problem since it has no effect on those of us that aren't members.

The SDA doesn't seem to enforce these rules though since the patches included
here are based on documentation made public by some of the members.  The most
complete specs[2] are actually released by Sandisk, one of the founding
companies of the SDA.

Because of this the NDA is considered a non-issue by most involved in the
discussions concerning these patches.  It might be that the SDA is only
interested in protecting the so called "secure" bits of SD, which so far
hasn't been found in any public spec.  (The card is split into two sections,
one "normal" and one "secure" which has an access scheme similar to TPM:s).

(As a side note, Microsoft is working to make things easier for us since they
want to be able to include the source code for a SD driver in one of their
development kits.  HP is making sure that the new NDA will allow a Linux
implementation.  So far only the SDIO specs have been opened up[3].  More will
hopefully follow.)

 [2] http://www.sandisk.com/pdf/oem/ProdManualSDCardv1.9.pdf
 [3] http://www.sdcard.org/sdio/Simplified%20SDIO%20Card%20Specification.pdf

This patch contains the central parts of the SD support.  If no MMC cards are
found on a bus then the MMC layer proceeds looking for SD cards.  Helper
functions are extended to handle the special needs of SD cards.

[PATCH] fix: dmi_check_system

Background:

1) dmi_check_system() returns the count of the number of

2) A match callback can return nonzero to stop the match
   checking.

Bug: The count is incremented after we check for the nonzero return value,
so it does not reflect the actual count.  We could say this is intended,
for some dumb reason, except that it means that a match on the first check
returns zero--no matches--if the callback returns nonzero.

This patch moves d_hash in the same cache line than d_parent and d_name

1) One cache line is needed instead of two.

2) the hlist_for_each_rcu() prefetching has a chance to bring all the

I also changed one old comment that was wrong for 64bits.

is mostly read, and one writen (d_count/d_lock) to avoid false sharing on

[PATCH] cpusets: formalize intermediate GFP_KERNEL containment

This patch makes use of the previously underutilized cpuset flag
'mem_exclusive' to provide what amounts to another layer of memory placement
resolution.  With this patch, there are now the following four layers of
memory placement available:

 1) The whole system (interrupt and GFP_ATOMIC allocations can use this),
 2) The nearest enclosing mem_exclusive cpuset (GFP_KERNEL allocations can use),
 3) The current tasks cpuset (GFP_USER allocations constrained to here), and
 4) Specific node placement, using mbind and set_mempolicy.

These nest - each layer is a subset (same or within) of the previous.

Layer (2) above is new, with this patch.  The call used to check whether a
zone (its node, actually) is in a cpuset (in its mems_allowed, actually) is
extended to take a gfp_mask argument, and its logic is extended, in the case
that __GFP_HARDWALL is not set in the flag bits, to look up the cpuset
hierarchy for the nearest enclosing mem_exclusive cpuset, to determine if
placement is allowed.  The definition of GFP_USER, which used to be identical
to GFP_KERNEL, is changed to also set the __GFP_HARDWALL bit, in the previous
cpuset_gfp_hardwall_flag patch.

GFP_ATOMIC and GFP_KERNEL allocations will stay within the current tasks
cpuset, so long as any node therein is not too tight on memory, but will
escape to the larger layer, if need be.

The intended use is to allow something like a batch manager to handle several
jobs, each job in its own cpuset, but using common kernel memory for caches
and such.  Swapper and oom_kill activity is also constrained to Layer (2).  A
task in or below one mem_exclusive cpuset should not cause swapping on nodes
in another non-overlapping mem_exclusive cpuset, nor provoke oom_killing of a
task in another such cpuset.  Heavy use of kernel memory for i/o caching and
such by one job should not impact the memory available to jobs in other
non-overlapping mem_exclusive cpusets.

This patch enables providing hardwall, inescapable cpusets for memory
allocations of each job, while sharing kernel memory allocations between
several jobs, in an enclosing mem_exclusive cpuset.

Like Dinakar's patch earlier to enable administering sched domains using the
cpu_exclusive flag, this patch also provides a useful meaning to a cpuset flag
that had previously done nothing much useful other than restrict what cpuset
configurations were allowed.

Paul Jackson [Tue, 6 Sep 2005 22:18:09 +0000 (15:18 -0700)]
[PATCH] cpusets: oom_kill tweaks

This patch series extends the use of the cpuset attribute 'mem_exclusive'
to support cpuset configurations that:
 1) allow GFP_KERNEL allocations to come from a potentially larger
    set of memory nodes than GFP_USER allocations, and
 2) can constrain the oom killer to tasks running in cpusets in
    a specified subtree of the cpuset hierarchy.

Here's an example usage scenario.  For a few hours or more, a large NUMA
system at a University is to be divided in two halves, with a bunch of student
jobs running in half the system under some form of batch manager, and with a
big research project running in the other half.  Each of the student jobs is
placed in a small cpuset, but should share the classic Unix time share
facilities, such as buffered pages of files in /bin and /usr/lib.  The big
research project wants no interference whatsoever from the student jobs, and
has highly tuned, unusual memory and i/o patterns that intend to make full use
of all the main memory on the nodes available to it.

In this example, we have two big sibling cpusets, one of which is further
divided into a more dynamic set of child cpusets.

We want kernel memory allocations constrained by the two big cpusets, and user
allocations constrained by the smaller child cpusets where present.  And we
require that the oom killer not operate across the two halves of this system,
or else the first time a student job runs amuck, the big research project will
likely be first inline to get shot.

Tweaking /proc/<pid>/oom_adj is not ideal -- if the big research project
really does run amuck allocating memory, it should be shot, not some other
task outside the research projects mem_exclusive cpuset.

I propose to extend the use of the 'mem_exclusive' flag of cpusets to manage
such scenarios.  Let memory allocations for user space (GFP_USER) be
constrained by a tasks current cpuset, but memory allocations for kernel space
(GFP_KERNEL) by constrained by the nearest mem_exclusive ancestor of the
current cpuset, even though kernel space allocations will still _prefer_ to
remain within the current tasks cpuset, if memory is easily available.

Let the oom killer be constrained to consider only tasks that are in
overlapping mem_exclusive cpusets (it won't help much to kill a task that
normally cannot allocate memory on any of the same nodes as the ones on which
the current task can allocate.)

The current constraints imposed on setting mem_exclusive are unchanged.  A
cpuset may only be mem_exclusive if its parent is also mem_exclusive, and a
mem_exclusive cpuset may not overlap any of its siblings memory nodes.

This patch was presented on linux-mm in early July 2005, though did not
generate much feedback at that time.  It has been built for a variety of
arch's using cross tools, and built, booted and tested for function on SN2
(ia64).

There are 4 patches in this set:
  1) Some minor cleanup, and some improvements to the code layout
     of one routine to make subsequent patches cleaner.
  2) Add another GFP flag - __GFP_HARDWALL.  It marks memory
     requests for USER space, which are tightly confined by the
     current tasks cpuset.
  3) Now memory requests (such as KERNEL) that not marked HARDWALL can
     if short on memory, look in the potentially larger pool of memory
     defined by the nearest mem_exclusive ancestor cpuset of the current
     tasks cpuset.
  4) Finally, modify the oom killer to skip any task whose mem_exclusive
     cpuset doesn't overlap ours.

Patch (1), the one time I looked on an SN2 (ia64) build, actually saved 32

about 600 bytes each of kernel text space, mostly in kernel/cpuset.c, which
matters only if CONFIG_CPUSET is enabled.

This patch:

This patch applies a few comment and code cleanups to mm/oom_kill.c prior to
applying a few small patches to improve cpuset management of memory placement.

The comment changed in oom_kill.c was seriously misleading.  The code layout
change in select_bad_process() makes room for adding another condition on
which a process can be spared the oom killer (see the subsequent
cpuset_nodes_overlap patch for this addition).

Also a couple typos and spellos that bugged me, while I was here.

19 years ago[PATCH] ia64 cpuset + build_sched_domains() mangles structures
John Hawkes [Tue, 6 Sep 2005 22:18:06 +0000 (15:18 -0700)]
[PATCH] ia64 cpuset + build_sched_domains() mangles structures

I've already sent this to the maintainers, and this is now being sent to a
larger community audience.  I have fixed a problem with the ia64 version of
build_sched_domains(), but a similar fix still needs to be made to the
generic build_sched_domains() in kernel/sched.c.

The "dynamic sched domains" functionality has recently been merged into
2.6.13-rcN that sees the dynamic declaration of a cpu-exclusive (a.k.a.
"isolated") cpuset and rebuilds the CPU Scheduler sched domains and sched
groups to separate away the CPUs in this cpu-exclusive cpuset from the
remainder of the non-isolated CPUs.  This allows the non-isolated CPUs to
completely ignore the isolated CPUs when doing load-balancing.

Unfortunately, build_sched_domains() expects that a sched domain will
include all the CPUs of each node in the domain, i.e., that no node will
belong in both an isolated cpuset and a non-isolated cpuset.  Declaring a
cpuset that violates this presumption will produce flawed data structures
and will oops the kernel.

To trigger the problem (on a NUMA system with >1 CPUs per node):
   cd /dev/cpuset
   mkdir newcpuset
   cd newcpuset
   echo 0 >cpus
   echo 0 >mems
   echo 1 >cpu_exclusive

I have fixed this shortcoming for ia64 NUMA (with multiple CPUs per node).
A similar shortcoming exists in the generic build_sched_domains() (in
kernel/sched.c) for NUMA, and that needs to be fixed also.  The fix
involves dynamically allocating sched_group_nodes[] and
sched_group_allnodes[] for each invocation of build_sched_domains(), rather
than using global arrays for these structures.  Care must be taken to
remember kmalloc() addresses so that arch_destroy_sched_domains() can
properly kfree() the new dynamic structures.

[PATCH] block: CFQ refcounting fix

I ran across a memory leak related to the cfq scheduler. The cfq
init function increments the refcnt of the associated request_queue.

This refcount gets decremented in cfq's exit function. Since blk_cleanup_queue
only calls the elevator exit function when its refcnt goes to zero, the
request_q never gets cleaned up. It didn't look like other io schedulers were
incrementing this refcnt, so I removed the refcnt increment and it fixed the
memory leak for me.

To reproduce the problem, simply use cfq and use the scsi_host scan sysfs
attribute to scan "- - -" repeatedly on a scsi host and watch the memory
vanish.

inode cache creating a duplicate in the inode cache.

The big issue here is that the buffers associated with each inode cache entry
are not shared between the duplicates!

The older inode entries are now orphaned as no dentry points to it and won't
be freed until the buffer cache assoicated with them are first freed.  The
newest entry will have to create all new buffer cache for each part of its
file as the old buffer cache is now orphaned as well.

Patch below fixes this by making get_cramfs_inode() use the inode cache before
blindly creating a new entry every time.  This eliminates the duplicate inodes
and duplicate buffer cache.

[PATCH] remove a redundant variable in sys_prctl()

The patch removes a redundant variable `sig' from sys_prctl().

For some reason, when sys_prctl is called with option == PR_SET_PDEATHSIG
then the value of arg2 is assigned to an int variable named sig.  Then sig
is tested with valid_signal() and later used to set the value of
current->pdeath_signal .

There is no reason to use this intermediate variable since valid_signal()
takes a unsigned long argument, so it can handle being passed arg2
directly, and if the call to valid_signal is OK, then we know the value of
arg2 is in the range zero to _NSIG and thus it'll easily fit in a plain int
and thus there's no problem assigning it later to current->pdeath_signal
(which is an int).

The patch gets rid of the pointless variable `sig'.
This reduces the size of kernel/sys.o in 2.6.13-rc6-mm1 by 32 bytes on my
system.

Patch has been compile tested, boot tested, and just to make damn sure I
didn't break anything I wrote a quick test app that calls
prctl(PR_SET_PDEATHSIG ...) with the entire range of values for a
unsigned long, and it behaves as expected with and without the patch.

Peter Staubach [Tue, 6 Sep 2005 22:17:35 +0000 (15:17 -0700)]
[PATCH] largefile support for accounting

There is a problem in the accounting subsystem in the kernel can not
correctly handle files larger than 2GB.  The output file containing the
process accounting data can grow very large if the system is large enough
and active enough.  If the 2GB limit is reached, then the system simply
stops storing process accounting data.

Another annoying problem is that once the system reaches this 2GB limit,
then every process which exits will receive a signal, SIGXFSZ.  This signal
is generated because an attempt was made to write beyond the limit for the
file descriptor.  This signal makes it look like every process has exited
due to a signal, when in fact, they have not.

The solution is to add the O_LARGEFILE flag to the list of flags used to
open the accounting file.  The rest of the accounting support is already
largefile safe.

The changes were tested by constructing a large file (just short of 2GB),
enabling accounting, and then running enough commands to cause the
accounting data generated to increase the size of the file to 2GB.  Without
the changes, the file grows to 2GB and the last command run in the test
script appears to exit due a signal when it has not.  With the changes,
things work as expected and quietly.

There are some user level changes required so that it can deal with
largefiles, but those are being handled separately.

[PATCH] Fix function/macro name collision on i386 oprofile

The i386 OProfile code has a function named nmi_exit(), which collides with

hardirq.h to oprofile.

Regardless, the name collision is probably not a good idea, so this patch
fixes it, renaming the oprofile function to op_nmi_exit().  It also renames
the nmi_init() and nmi_timer_init() functions similarly, for consistency.
