[ACPI] ACPICA 20060113

Added 2006 copyright.

At SuSE's suggestion, enabled all error messages
without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n

Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages
in the non-debug version of the ACPICA code (this has been
referred to as the "debug lite" option.) Over 200 cases
were converted to create a total of over 380 error/warning
messages across the ACPICA code. This increases the code
and data size of the default non-debug version by about 13K.
Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
The size of the debug version remains about the same.

[ACPI] enable PNPACPI support for resource types used by HP serial ports

PNPACPI complained about and ignored devices with ADDRESS16, ADDRESS32, or
ADDRESS64 descriptors in _PRS.  HP firmware uses them for built-in serial
ports, so this patch adds support for parsing these descriptors from _PRS.

Note that this does not add the corresponding support for encoding them in
preparation for _SRS, because I don't have any machine that supports _SRS
on these descriptors, so I couldn't test that support.  Attempts to encode
them will cause a warning and an -EINVAL return.

15 years ago[PATCH] Fix posix-cpu-timers sched_time accumulation
David S. Miller [Fri, 6 Jan 2006 23:36:48 +0000]
[PATCH] Fix posix-cpu-timers sched_time accumulation

I've spent the past 3 days digging into a glibc testsuite failure in
current CVS, specifically libc/rt/tst-cputimer1.c The thr1 and thr2
timers fire too early in the second pass of this test.  The second
pass is noteworthy because it makes use of intervals, whereas the
first pass does not.

All throughout the posix-cpu-timers.c code, the calculation of the
process sched_time sum is implemented roughly as:

unsigned long long sum;

sum = tsk->signal->sched_time;
t = tsk;
do {
sum += t->sched_time;
t = next_thread(t);
} while (t != tsk);

In fact this is the exact scheme used by check_process_timers().

In the case of check_process_timers(), current->sched_time has just
been updated (via scheduler_tick(), which is invoked by
update_process_times(), which subsequently invokes
run_posix_cpu_timers()) So there is no special processing necessary
wrt. that.

In other contexts, we have to allot for the fact that tsk->sched_time
might be a bit out of date if we are current.  And the
posix-cpu-timers.c code uses current_sched_time() to deal with that.

Unfortunately it does so in an erroneous and inconsistent manner in
one spot which is what results in the early timer firing.

In cpu_clock_sample_group_locked(), it does this:

cpu->sched = p->signal->sched_time;
/* Add in each other live thread.  */
while ((t = next_thread(t)) != p) {
cpu->sched += t->sched_time;
}
if (p->tgid == current->tgid) {
/*
 * We're sampling ourselves, so include the
 * cycles not yet banked.  We still omit
 * other threads running on other CPUs,
 * so the total can always be behind as
 * much as max(nthreads-1,ncpus) * (NSEC_PER_SEC/HZ).
 */
cpu->sched += current_sched_time(current);
} else {
cpu->sched += p->sched_time;
}

The problem is the "p->tgid == current->tgid" test.  If "p" is
not current, and the tgids are the same, we will add the process
t->sched_time twice into cpu->sched and omit "p"'s sched_time
which is very very very wrong.

posix-cpu-timers.c has a helper function, sched_ns(p) which takes care
of this, so my fix is to use that here instead of this special tgid
test.

The fact that current can be one of the sub-threads of "p" points out
that we could make things a little bit more accurate, perhaps by using
sched_ns() on every thread we process in these loops.  It also points
out that we don't use the most accurate value for threads in the group
actively running other cpus (and this is mentioned in the comment).

But that is a future enhancement, and this fix here definitely makes
sense.

Shaun Pereira [Fri, 6 Jan 2006 21:11:35 +0000]
[X25]: Fix for broken x25 module.

When a user-space server application calls bind on a socket, then in kernel
space this bound socket is considered 'x25-linked' and the SOCK_ZAPPED flag
is unset.(As in x25_bind()/af_x25.c).

Now when a user-space client application attempts to connect to the server
on the listening socket, if the kernel accepts this in-coming call, then it
returns a new socket to userland and attempts to reply to the caller.

The reply/x25_sendmsg() will fail, because the new socket created on
call-accept has its SOCK_ZAPPED flag set by x25_make_new().
(sock_init_data() called by x25_alloc_socket() called by x25_make_new()
sets the flag to SOCK_ZAPPED)).

Fix: Using the sock_copy_flag() routine available in sock.h fixes this.

Tested on 32 and 64 bit kernels with x25 over tcp.

SUNRPC: new interface to force an RPC rebind

 We'd like to hide fields in rpc_xprt and rpc_clnt from upper layer protocols.
 Start by creating an API to force RPC rebind, replacing logic that simply
 sets cl_port to zero.

 Test-plan:
 Destructive testing (unplugging the network temporarily).  Connectathon
 with UDP and TCP.  NFSv2/3 and NFSv4 mounting should be carefully checked.

SUNRPC: switchable buffer allocation

 Add RPC client transport switch support for replacing buffer management
 on a per-transport basis.

 In the current IPv4 socket transport implementation, RPC buffers are
 allocated as needed for each RPC message that is sent.  Some transport
 implementations may choose to use pre-allocated buffers for encoding,
 sending, receiving, and unmarshalling RPC messages, however.  For
 transports capable of direct data placement, the buffers can be carved
 out of a pre-registered area of memory rather than from a slab cache.

 Test-plan:
 Millions of fsx operations.  Performance characterization with "sio" and
 "iozone".  Use oprofile and other tools to look for significant regression
 in CPU utilization.

NFSv3: try get_root user-supplied security_flavor

 Thanks to Ed Keizer for bug and root cause.  He says: "... we could only mount
 the top-level Solaris share. We could not mount deeper into the tree.
 Investigation showed that Solaris allows UNIX authenticated FSINFO only on the
 top level of the share. This is a problem because we share/export our home
 directories one level higher than we mount them. I.e. we share the partition
 and not the individual home directories. This prevented access to home
 directories."

 We still may need to try auth_sys for the case where the client doesn't have
 appropriate credentials.

NLM: Further cancel fixes

 If the server receives an NLM cancel call and finds no waiting lock to
 cancel, then chances are the lock has already been applied, and the client
 just hadn't yet processed the NLM granted callback before it sent the
 cancel.

 The Open Group text, for example, perimts a server to return either success
 (LCK_GRANTED) or failure (LCK_DENIED) in this case.  But returning an error
 seems more helpful; the client may be able to use it to recognize that a
 race has occurred and to recover from the race.

 So, modify the relevant functions to return an error in this case.

 Currently when lockd gets an NLM_CANCEL request, it also does an unlock for

 The Open Group documentation says that "This procedure cancels an
 *outstanding* blocked lock request."  (Emphasis mine.)

 Also, consider a client that holds a lock on the first byte of a file, and
 requests a lock on the entire file.  If the client cancels that request
 (perhaps because the requesting process is signalled), the server shouldn't
 apply perform an unlock on the entire file, since that will also remove the
 previous lock that the client was already granted.

 Or consider a lock request that actually *downgraded* an exclusive lock to
 a shared lock.

Andrew Morton [Wed, 16 Nov 2005 23:07:01 +0000]
identify multipage ->writepages() calls

 NFS needs to be able to distinguish between single-page ->writepage() calls and
 multipage ->writepages() calls.

 For the single-page writepage calls NFS can kick off the I/O within the
 context of ->writepage().

 For multipage ->writepages calls, nfs_writepage() will leave the I/O pending
 and nfs_writepages() will kick off the I/O when it all has been queued up
 within NFS.

15 years agokbuild: Use git in scripts/setlocalversion
Rene Scharfe [Wed, 4 Jan 2006 19:42:03 +0000]
kbuild: Use git in scripts/setlocalversion

Currently scripts/setlocalversion is a Perl script that tries to figure
out the current git commit ID of a repo without using git.  It also
imports Digest::MD5 without using it and generally is too big for the
small task it does. :]  And it always reports a git ID, even when the
HEAD is tagged -- this is a bug.

This patch replaces it with a Bourne Shell script that uses git
commands to do the same.  I can't come up with a scenario where someone
would use a git repo and refuse to install git core at the same time,
so I think it's reasonable to assume git is available.

The new script also reports uncommitted changes by adding -git_dirty to
the version string.  Obviously you can't see from that _what_ has been
changed from the last commit, so it's more of a reminder that you
forgot to commit something.

The script is easily extensible: simply add a check for Mercurial (or
whatever) below the git check.

Note: the script doesn't print a newline char anymore.  That's only
because it was easier to implement it that way, not a feature (or bug).
'make kernelrelease' doesn't care.

This was harmless, but for the case of a device that had no irq
pre-defined we would incorrectly suggest that "usepirqmask" might make a
difference.  It never would, and the message was just confusing people.

[PATCH] Suspend support for libata

This patch adds suspend patch to libata, and ata_piix in particular. For
most low level drivers, they should just need to add the 4 hooks to
work. As I can only test ata_piix, I didn't enable it for more
though.

Suspend support is the single most important feature on a notebook, and
most new notebooks have sata drives. It's quite embarrassing that we
_still_ do not support this. Right now, it's perfectly possible to
suspend the drive in mid-transfer.
