13 years agofix clone(CLONE_NEWPID)
Eric W. Biederman [Wed, 5 Dec 2007 07:45:04 +0000]
fix clone(CLONE_NEWPID)

Currently we are complicating the code in copy_process, the clone ABI, and
if we fix the bugs sys_setsid itself, with an unnecessary open coded
version of sys_setsid.

So just simplify everything and don't special case the session and pgrp of
the initial process in a pid namespace.

Having this special case actually presents to user space the classic linux
startup conditions with session == pgrp == 0 for /sbin/init.

We already handle sending signals to processes in a child pid namespace.

We need to handle sending signals to processes in a parent pid namespace
for cases like SIGCHILD and SIGIO.

This makes nothing extra visible inside a pid namespace.  So this extra
special case appears to have no redeeming merits.

Further removing this special case increases the flexibility of how we can
use pid namespaces, by not requiring the initial process in a pid namespace
to be a daemon.

sata_mv:  Warn about HPT RocketRAID BIOS treatment of "Legacy" drives

The Highpoint RocketRAID boards using Marvell 7042 chips
overwrite the 9th sector of attached drives at boot time,
when those drives are configured as "Legacy" (the default)
in the HighPoint BIOS.

This kills GRUB, and probably other stuff.
But it all happens *before* Linux is even loaded.

So, for now we'll log a WARNING when such boards are detected,
and advise users to configure BIOS "JBOD" volumes instead,
which don't appear to suffer from this problem.

[S390] Fix compile error on 31bit without preemption

Commit b8e7a54cd06b0b0174029ef3a7f5a1415a2c28f2 introduced a compile
error if CONFIG_PREEMPT is not set:

arch/s390/kernel/built-in.o: In function `cleanup_io_leave_insn':
/space/kvm/arch/s390/kernel/entry.S:(.text+0xbfce): undefined reference to `preempt_schedule_irq'

This patch hides preempt_schedule_irq if CONFIG_PREEMPT is not set.

[S390] dcssblk: prevent early access without own make_request function

When loading a dcss segment with the dcssblk driver, sometimes the
following kind of message appears:

bio too big device dcssblk0 (8 > 0)
Buffer I/O error on device dcssblk0, logical block 172016
..

The fix is to move the disk registration after setting the
make_request function, to avoid calls into generic_make_request
for dcssblock without having the make_request function set up
properly.

[S390] cio: Issue SenseID per path.

We may receive a unit check for every path when we issue a SenseID.
Unfortunately, the channel subsystem will try on a different path
every time if we use a lpm of 0xff, which will exhaust our retry

Therefore, revert SenseID to its previous per-path behaviour and
just leave out the suspend multipath reconnect.

If HPET was enabled by pci quirks, we use i8253 as initial clockevent
because pci quirks doesn't run until pci is initialized.

The above means the kernel (or something) is assuming HPET legacy
replacement is disabled and can use i8253 at boot.

unresolved. According to the ACPI specification, a Package can
only contain Data Objects or references to control methods. The
implication is that named references to Data Objects (Integer,
Buffer, String, Package, BufferField, Field) should be resolved
immediately upon package creation. This is the approach taken

13 years agosched: cpu accounting controller (V2)
Srivatsa Vaddagiri [Sun, 2 Dec 2007 19:04:49 +0000]
sched: cpu accounting controller (V2)

Commit cfb5285660aad4931b2ebbfa902ea48a37dfffa1 removed a useful feature for
us, which provided a cpu accounting resource controller.  This feature would be
useful if someone wants to group tasks only for accounting purpose and doesnt
really want to exercise any control over their cpu consumption.

The patch below reintroduces the feature. It is based on Paul Menage's
original patch (Commit 62d0df64065e7c135d0002f069444fbdfc64768f), with
these differences:

        - Removed load average information. I felt it needs more thought (esp
  to deal with SMP and virtualized platforms) and can be added for
  2.6.25 after more discussions.
        - Convert group cpu usage to be nanosecond accurate (as rest of the cfs
  stats are) and invoke cpuacct_charge() from the respective scheduler
  classes
- Make accounting scalable on SMP systems by splitting the usage
  counter to be per-cpu
- Move the code from kernel/cpu_acct.c to kernel/sched.c (since the
  code is not big enough to warrant a new file and also this rightly
  needs to live inside the scheduler. Also things like accessing
  rq->lock while reading cpu usage becomes easier if the code lived in
  kernel/sched.c)

The patch also modifies the cpu controller not to provide the same accounting
information.

Tested-by: Balbir Singh <balbir@linux.vnet.ibm.com>

 Tested the patches on top of 2.6.24-rc3. The patches work fine. Ran
 some simple tests like cpuspin (spin on the cpu), ran several tasks in
 the same group and timed them. Compared their time stamps with
 cpuacct.usage.

The IRQ operation(enable/disable) should be avoided when throttling is

13 years agosata_mv: Fix broken Marvell 7042 support.
Mark Lord [Sat, 1 Dec 2007 18:07:22 +0000]
sata_mv: Fix broken Marvell 7042 support.

sata_mv:  Fix broken Marvell 7042 support.

The Marvell 7042 chip is more or less the same as the 6042 internally,
but sports a PCIe bus.  Despite having identical SATA cores, the 7042
does differ from its PCI bus counterparts in placment and layout of
certain bus related registers.

This patch fixes sata_mv to distinguish between the PCI bus registers
of earlier chips, and the PCIe bus registers of the 7042.

Specifically, move the offsets and bit patterns for the
PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv,
as these values differ between the 6xxx and 7xxx series chips.

This fixes the driver to not access reserved PCI addresses,
and prevents the lockups reported in linux-2.6.24 with 7042 boards.

Also add a new PCI ID for the Highpoint 2300 7042-based board
that I'm using for testing this stuff here.

Tested with Marvell 6081 + 7042 chips, on x86 & x86_64.

Eric W. Biederman [Sat, 1 Dec 2007 13:33:17 +0000]
[NETNS]: Fix /proc/net breakage

Well I clearly goofed when I added the initial network namespace support
for /proc/net.  Currently things work but there are odd details visible to
user space, even when we have a single network namespace.

Since we do not cache proc_dir_entry dentries at the moment we can just
modify ->lookup to return a different directory inode depending on the
network namespace of the process looking at /proc/net, replacing the
current technique of using a magic and fragile follow_link method.

To accomplish that this patch:
- introduces a shadow_proc method to allow different dentries to
  be returned from proc_lookup.
- Removes the old /proc/net follow_link magic
- Fixes a weakness in our not caching of proc generic dentries.

As shadow_proc uses a task struct to decided which dentry to return we can
go back later and fix the proc generic caching without modifying any code
that uses the shadow_proc method.
