==== diff-vzdq-quotafile-20050929 ====
<div class="change">Patch from Andrey:
This patch reimplements /proc/vz/vzaquota - a directory containing
entries for each vzquota-enabled superblock with aquota.user and
aquota.group files.
The goal is to support standard quota tools and allow VPSs
to have multiple quota partitions.
Entries in /proc/vz/vzaquota are device numbers of the superblocks
(a single 32-bit hexadecimal value as returned by sys_stat64, not
a major-minor pair).
No VE start/stop hooks are used in this implementation.
Compilation with unusual config options was fixed where I noticed.

==== diff-proc-moduleget-20050930 ====
<div class="change">Patch from Denis:

==== diff-ubc-vmamerge-20050930 ====
<div class="change">Patch from Alexey:<br/>
Fix NULL dereference in vma_merge.
It is funny how gcc compiled it. gcc figured out that the pointer
can be NULL sometimes and compiled a separate(!) block for this case,
which was optimized to understand that the pointer is NULL.

==== diff-fairsched-singlelock-20050929 ====
<div class="change">Patch from Kirill:<br/>
This patch is from fairsched performance improving series:

* this also prepares code for balancing activation
* remove wrong BUG_ON in vcpu_put. on schedule_vcpu() restart VCPU can be already get...

<div class="change">Patch from mainstream:<br/>
[PATCH] Buffer overrun in arch/x86_64/sys_ia32.c:sys32_ni_syscall()
struct task_struct.comm is defined to be 16 chars, but
arch/x86_64/sys_ia32.c:sys32_ni_syscall() and sys32_vm86_warning() copy it
into a static 8 byte buffer, which will surely cause problems. This patch
makes lastcomm[] the right size, and makes sure it can't be overrun. Since
the code also goes to the effort of getting a local copy of current in "me",
we may as well use it for printing the message.

phys_proc_id gets initialized only when (smp_num_siblings > 1). But gets
printed even when (smp_num_siblings == 1). As a result we print incorrect
physical processor id in /proc/cpuinfo, when HT is disabled.

<div class="change">Patch from mainstream:<br/>
[PATCH] x86_64: Fix lost edge triggered irqs on UP kernel
There are problems with IDE disks while running UP kernel on
x86-64 - it complained a lot about lost irq from hda/hdc. At enable_irq() code
calls hw_resend_irq(), but on x86-64 hw_resend_irq() does something useful only
when CONFIG_SMP is defined, on UP systems it does nothing. Due to this IRQ is
lost - and when IDE retries command, it can again happen
that IRQ is delivered before IDE code does enable_irq(), and again and
again, unless due to drive being lazy finally once kernel does enable_irq()
before drive prepares its answer, and things move forward ... to next lost
IRQ.

<div class="change">Patch from mainstream:<br/>
[PATCH] x86_64: no TIOCSBRK/TIOCCBRK in ia32 emulation
In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and
TIOCCBRK with EINVAL. I've attached a patch that adds them to the
compatibility list.
Since all architectures have these ioctls ("m68knommu" inherits them from
"m68k", "um" from its host) and use the same code, I think adding them to
compat_ioctl.h is the correct choice (as opposed to adding them to
arch/x86_64/ia32/ia32_ioctl.c).

This patch replaces temporary diff-fairsched-amd-20051010,

Correct solution is to keep both fairscheduler and vsched

of running VCPUs. So fairsched will select node for scheduling
_only_ if it have an active selectable VCPU. The whole
restart path in one place has gone.

[PATCH] x86_64: TASK_SIZE fixes for compatibility mode processes
Appended patch will setup compatibility mode TASK_SIZE properly. This will
fix atleast three known bugs that can be encountered while running
compatibility mode apps.
<li>A malicious 32bit app can have an elf section at 0xffffe000. During
exec of this app, we will have a memory leak as insert_vm_struct() is
not checking for return value in syscall32_setup_pages() and thus not
freeing the vma allocated for the vsyscall page. And instead of exec
failing (as it has addresses > TASK_SIZE), we were allowing it to
succeed previously.
<li>With a 32bit app, hugetlb_get_unmapped_area/arch_get_unmapped_area
may return addresses beyond 32bits, ultimately causing corruption
because of wrap-around and resulting in SEGFAULT, instead of returning
ENOMEM.
* 32bit app doing this below mmap will now fail.

==== diff-ms-sendfile-20051007 ====
<div class="change">Patch from mainstream, ported by Pavel:
If we use 64bit kernel on ia64/x86_64/s390 architecture, and we run
32bit binary on 32bit compatibility mode, sendfile system call seems
not set offset argument.
This is because sendfile's return value is not zero but the code

[PATCH] forcedeth: Initialize link settings in every nv_open()
Rdiger found a bug in nv_open that explains some of the reports
with duplex mismatches:<br/>
nv_open calls nv_update_link_speed for initializing the hardware link speed
registers. If current link setting matches the values in np->linkspeed and
np->duplex, then the function does nothing.
Usually, doing nothing is the right thing, but not in nv_open: During
nv_open, the registers must be initialized because the nic was reset.
The attached patch fixes that by setting np->linkspeed to an invalid value
before calling nv_update_link_speed from nv_open.

eth0: Memory squeeze,deferring packet.
eth0: NULL pointer encountered in Rx ring, skipping
* If counter cur_rx overflows and there'll be temporary memory problems buffer can't be recreated later, when memory IS avaliable.
* Limit the work in handler to prevent the endless packets processing if new packets are generated faster then handled.

[TCP]: Fix excessive stack usage resulting in OOPS with 4KSTACKS.
Various routines were putting a full struct tcp_sock on
the local stack. What they really wanted was a subset
of this information when doing TCP options processing
when we only have a mini-socket (for example in SYN-RECVD
and TIME_WAIT states).
Therefore pull out the needed information into a sub-struct
and use that in the TCP options processing routines.

<div class="change">Patch from Andrey:
This patch reimplements /proc/vz/vzaquota - a directory containing
entries for each vzquota-enabled superblock with aquota.user and
aquota.group files.
The goal is to support standard quota tools and allow VPSs
to have multiple quota partitions.
Entries in /proc/vz/vzaquota are device numbers of the superblocks
(a single 32-bit hexadecimal value as returned by sys_stat64, not
a major-minor pair).
No VE start/stop hooks are used in this implementation.
Compilation with unusual config options was fixed where I noticed.

[PATCH] x86_64: Fix lost edge triggered irqs on UP kernel
There are problems with IDE disks while running UP kernel on
x86-64 - it complained a lot about lost irq from hda/hdc. At enable_irq() code
calls hw_resend_irq(), but on x86-64 hw_resend_irq() does something useful only
when CONFIG_SMP is defined, on UP systems it does nothing. Due to this IRQ is
lost - and when IDE retries command, it can again happen
that IRQ is delivered before IDE code does enable_irq(), and again and
again, unless due to drive being lazy finally once kernel does enable_irq()
before drive prepares its answer, and things move forward ... to next lost
IRQ.

In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and

compatibility list.
Since all architectures have these ioctls ("m68knommu" inherits them from
"m68k", "um" from its host) and use the same code, I think adding them to
compat_ioctl.h is the correct choice (as opposed to adding them to
arch/x86_64/ia32/ia32_ioctl.c).

[PATCH] x86_64: TASK_SIZE fixes for compatibility mode processes
Appended patch will setup compatibility mode TASK_SIZE properly. This will
fix atleast three known bugs that can be encountered while running
compatibility mode apps.
<li>A malicious 32bit app can have an elf section at 0xffffe000. During
exec of this app, we will have a memory leak as insert_vm_struct() is
not checking for return value in syscall32_setup_pages() and thus not
freeing the vma allocated for the vsyscall page. And instead of exec
failing (as it has addresses > TASK_SIZE), we were allowing it to
succeed previously.
<li>With a 32bit app, hugetlb_get_unmapped_area/arch_get_unmapped_area
may return addresses beyond 32bits, ultimately causing corruption
because of wrap-around and resulting in SEGFAULT, instead of returning
ENOMEM.
* 32bit app doing this below mmap will now fail.

[PATCH] forcedeth: Initialize link settings in every nv_open()
Rdiger found a bug in nv_open that explains some of the reports
with duplex mismatches:<br/>
nv_open calls nv_update_link_speed for initializing the hardware link speed
registers. If current link setting matches the values in np->linkspeed and
np->duplex, then the function does nothing.
Usually, doing nothing is the right thing, but not in nv_open: During
nv_open, the registers must be initialized because the nic was reset.
The attached patch fixes that by setting np->linkspeed to an invalid value
before calling nv_update_link_speed from nv_open.

[PATCH] Fix fs/exec.c:788 (de_thread()) BUG_ON
It turns out that the BUG_ON() in fs/exec.c: de_thread() is unreliable
and can trigger due to the test itself being racy.
And actually there is no need for all threads to have exited at this
point, so we simply kill the BUG_ON.

==== diff-ve-percpu-lat-sched-20051003 ====
<div class="change">Patch from Pavel:
This patch makes schedule() use kstat_lat_pcpu_struct to store
info about scheduling latencies. This makes possible to avoid
taking kstat_glob_lock in schedule().
</div>
==== diff-ve-percpu-lat-20051003 ====
<div class="change">Patch from Pavel:
Adds kstat_lat_pcpu_struct to account latencies per-cpu.
It will be used in schedule() to avoid using kstat_glob_lock.

==== diff-ve-devnum-20051005 ====
<div class="change">Patch from Andrey:
This patch transfers bits 8..11 of unnamed device minor into major,
using additional major numbers, which is currently enough for 1000 VEs.
It is needed as a bandaid for coreutils (e.g., mknod) that still cannot
use minor or major numbers >= 256; mknod on unnamed devices is used
for support of second level quota inside VE.
</div>
==== diff-fairsched-lock-20051006 ====
<div class="change">Patch from Pavel:
When CONFIG_FAIRSCHED is not set fairsched_lock is not present in
kernel, but vcpu scheduler uses it to synchronize it's own stuff.
Added spinlock with the same name nuder appropriate #ifdef having
nothing better in mind.
</div>
==== diff-fairsched-shownode-20051006 ====
<div class="change">Patch from Pavel, modified by Kirill:<br/>

</div>
==== diff-fairsched-migrateall-20051007 ====
<div class="change">Patch from Kirill:
This patch replaces std migrate_all_tasks() with own
version for VCPU scheduler. It doesn't migrate any tasks now,
just do sanity checks. It fixes compilation of IA64 kernel,
since it used cpu_to_node() macro before...

==== diff-sis900-20051014 ====
<div class="change">Patch from Konstantin:
Patch solves following problems:
* Forgotten counter incrementation in sis900_rx() in case it doesn't get memory for skb, that leads to whole interface failure. Problem is accompanied with messages:
eth0: Memory squeeze,deferring packet.
eth0: NULL pointer encountered in Rx ring, skipping
* If counter cur_rx overflows and there'll be temporary memory problems buffer can't be recreated later, when memory IS avaliable.
* Limit the work in handler to prevent the endless packets processing if new packets are generated faster then handled.

==== diff-ubc-debug-types-20051018 ====
<div class="change">Patch from Pavel:
Since ub_pages_charged and ub_vmalloc_charged are per-cpu they
can sometimes be negative. According type (long instead of unsigned
int) is needed and appropriate struts in ubd_show() (print this
info into proc file) function.

==== diff-ms-tcpstackusg-20050222 ====
<div class="change">Patch from mainstream, ported by Denis:<br/>
[TCP]: Fix excessive stack usage resulting in OOPS with 4KSTACKS.
Various routines were putting a full struct tcp_sock on
the local stack. What they really wanted was a subset
of this information when doing TCP options processing
when we only have a mini-socket (for example in SYN-RECVD
and TIME_WAIT states).
Therefore pull out the needed information into a sub-struct
and use that in the TCP options processing routines.
