Questions about NAT and MASQ and more
Hello,
I''m working on a Shorewall-1.2 setup on a _remote_ debian (woody)
firewall with several live web and mail servers behind it. I know doing
this remotely is a *really* bad idea, and I''d rather not be in this
situation, but so it goes... Worst case scenario, I lock myself out and
have to drive an hour to get physical access to the machine and restore
service. Anyhow,

[PATCH v7 00/11] qspinlock: a 4-byte queue spinlock with PV support
v6->v7:
- Remove an atomic operation from the 2-task contending code
- Shorten the names of some macros
- Make the queue waiter to attempt to steal lock when unfair lock is
enabled.
- Remove lock holder kick from the PV code and fix a race condition
- Run the unfair lock & PV code on overcommitted KVM guests to collect
performance data.
v5->v6:
- Change the optimized

Luster clients getting evicted
on our cluster that has been running lustre for about 1 month. I have
1 MDT/MGS and 1 OSS with 2 OST''s.
Our cluster uses all Gige and has about 608 nodes 1854 cores.
We have allot of jobs that die, and/or go into high IO wait, strace
shows processes stuck in fstat().
The big problem is (i think) I would like some feedback on it that of
these 608 nodes 209 of them have in dmesg

[PATCH v8 00/10] qspinlock: a 4-byte queue spinlock with PV support
v7->v8:
- Remove one unneeded atomic operation from the slowpath, thus
improving performance.
- Simplify some of the codes and add more comments.
- Test for X86_FEATURE_HYPERVISOR CPU feature bit to enable/disable
unfair lock.
- Reduce unfair lock slowpath lock stealing frequency depending
on its distance from the queue head.
- Add performance data for IvyBridge-EX CPU.
