| Erez Zadok | [GIT PULL -mm] 0/9 Unionfs updates/cleanups/fixes
The following is a series of patches related to Unionfs. The main change
here is that unionfs now has its own ->writepages method.
These patches were tested (where appropriate) on Linus's 2.6.24 latest code
(as of v2.6.23-6623-g55b70a0), as well as the backports to
2.6.{23,22,21,20,19,18,9} on ext2/3/4, xfs, reiserfs, nfs2/3/4, jffs2,
ramfs, tmpfs, cramfs, and squashfs (where available). See
http://unionfs.filesystems.org/ to download backported unionfs code.
Please pull from the 'master' ...

This is no longer necessary since struct writeback_control no longer has a
fs_private field which lower file systems (esp. nfs) use. Plus, unionfs now

Therefore I have patched the modify_ldt syscall in ldt.c to generate a

| Artem Bityutskiy | forcing write-back from FS - again
Hi Andrew,
some time ago we were talking about doing write-back from inside a file-system
(http://marc.info/?l=linux-kernel&m=119097117713616&w=2). You said that I'm not
the only person who needs this, because the same thing is needed for delayed
allocation.
The problem is that if we initiate write-back from prepare_write() and we are
having a dirty page lock, we deadlock in write_cache_pages() which tries to
lock the same page.
You suggested to enhance struct writeback_control an...
| Oct 21, 4:19 pm 2007 |
| Andrew Morton | Re: forcing write-back from FS - again
We could just skip locked pages altogether in writeback. Perhaps in
WB_SYNC_NONE mode, or perhaps add a new flag in writeback_control to select
this behaviour.
It _should_ be the case that the number of locked-and-dirty pages which
writeback encounters is very small, so skipping locked pages during
writeback-for-memory-flushing won't have any significant effect. The first
step should be to add a new /proc/vmstat field to count these pages and
then do broad testing (especially on blocksize<...

Hi kernel gurus,
I am trying to find out the memory that's used on my linux box.
I find that there are quite a few confusing metrics. How do
I find out the "true" used memory ?
1. For eg. "free -m" shows free memory (excluding buffers/caches)
as 308 MB while I can see(from "df" output) that the the tmpfs
partitions take up about 400 MB. So, does "free -m" not consider
the tmpfs partitions ?

"ps aux" command. But is it true that this w...

| Vaidyanathan Srinivasan | Re: Question about free/used memory on Linux
pagecache pages may be the reason for the confusion. Most free memory can
be consumed under 'Cached' in /proc/meminfo
Most of this memory is easily reclaimable and can be considered 'free'.
However the cost of reclaim increases if the pages are memory mapped and/or
dirty.
Cached-Mapped-Dirty in /proc/meminfo can be seen as a easily freeable
memory and can be added to the 'Free' in /proc/meminfo count

Thanks for clarifying several of my doubts.
To answer your question about my intention, we currently have a
system with 2 GB RAM and I need to find out the actual used and
free memory so that we can decide if the same setup(applications,
tmpfs etc.) can run on another system with lesser memory.
Is it correct to say that the "used" field "free -m" excluding
buffers/caches would give the correct idea of used memory

That's right. I do depmod on i386 and amd64 for _all_ Debian architectures
without any problems and I don't see why it should be a problem when running
on other arches. It used to be a problem with depmod from modutils, but with
depmod from module-init-tools it works perfectly.
All it needs is the -b option and correct kernel version.

Hi,
I've run into a problem where a process trying to connect to a local
port within the local port range eventually ends up connected to itself,
with source port = dest port.
similar behavior can be gotten by running netcat as follows:
nc -p 1025 localhost 1025
I'm not really sure if that's a bug, but the original case was at least
unexpected.

Hi,
It is not a bug, it is caused by the "simultaneous connect" feature of
TCP. Although rarely used, in TCP you can connect two clients together.
They just have to exchange their SYN, SYN/ACK then ACK and bingo, they're
connected. In fact, you found the easiest way to achieve it, by using the
same port. To demonstrate the feature, I'm used to either temporarily
block SYNs with iptables, or by unplugging the cable between two machines.

Yes, it is a IPMI class code, only older versions of lspci know nothing

| Avi Kivity | [PATCH 00/11] KVM updates for Linux 2.6.24-rc review
The following patches fix fallout from the main 2.6.24 KVM merge. An
exception is the movnti emulation patch, which adds support for Linux
2.6.16 guests.
The patches can be found in kvm.git in the branch kvm-updates-2.6.24.
There is also a branch kvm-updates-2.6.25 which will form the basis of
the next merge window submission.
Please review the patches and let me know if something is wrong or if
a patch is missing.

What kind of comment do you want ?
What are the requirements to go in 2.6.24 instead of 2.6.25 ?
Is a bug correction enough ? :-P
This patch correct a bad behavior of x86_emulate_insn() in case of error with a
REP prefix.
This patch is needed because, without it, when REP prefix is used with an
instruction failing for some reasons (like IO or page fault) we don't restore
all modified registers (like RSI and RDI), but only ECX and EIP, so when we
re-enter in x86_emulate_insn() we modify a...

very different from kvm-updates-2.6.24...

Well, in fact it is not needed in 2.6.24, because this patch correct a bad
behavior introduced by commit 57f4e446ebca4aad5c11364baf8477c8cfcb16a4 (which is
not in kvm-update-2.6.24):
KVM: Call x86_decode_insn() only when needed
Move emulate_ctxt to kvm_vcpu to keep emulate context when we exit from kvm
module. Call x86_decode_insn() only when needed. Modify x86_emulate_insn() to
not modify the context if it must be re-entered.
So, in fact, the answer is (after correctly understanding the qu...

From: Kevin Pedretti <kevin.pedretti@gmail.com>
Better handle wrap-around cases when reading the APIC CCR
(current count register). Also, if ICR is 0, CCR should also
be 0... previously reading CCR before setting ICR would result
in a large kinda-random number.

| Avi Kivity | [PATCH 10/11] KVM: Fix local apic timer divide by zero
From: Kevin Pedretti <kevin.pedretti@gmail.com>
kvm_lapic_reset() was initializing apic->timer.divide_count to 0,
which could potentially lead to a divide by zero error in
apic_get_tmcct(). Any guest that reads the APIC's CCR (current count)
register before setting DCR (divide configuration) would trigger a divide
by zero exception in the host kernel, leading to a host-OS crash.
This patch results in apic->timer.divide_count being initialized to
2 at reset, eliminating the bug (DCR=0...

From: Laurent Vivier <Laurent.Vivier@bull.net>
We need to make sure that the timer interrupt happens before we clear
PF_VCPU, so the accounting code actually sees guest mode.
