[PATCH] uml - Fix x86_64 page leak

2005-10-03T23:27:18+00:00

We were leaking pmd pages when 3_LEVEL_PGTABLES was enabled. This fixes that,
has been well tested and is included in mainline tree. Please include in -stable
as well.

[PATCH] ipvs: ip_vs_ftp breaks connections using persistence

2005-10-03T23:27:18+00:00

	ip_vs_ftp when loaded can create NAT connections with unknown
client port for passive FTP. For such expectations we lookup with
cport=0 on incoming packet but it matches the format of the persistence
templates causing packets to other persistent virtual servers to be
forwarded to real server without creating connection. Later the
reply packets are treated as foreign and not SNAT-ed.

	If the IPVS box serves both FTP and other services (eg. HTTP)
for the time we wait for first packet for the FTP data connections with
unknown client port (there can be many), other HTTP connections
that have nothing common to the FTP conn break, i.e. HTTP client
sends SYN to the virtual IP but the SYN+ACK is not NAT-ed properly
in IPVS box and the client box returns RST to real server IP. I.e.
the result can be 10% broken HTTP traffic if 10% of the time
there are passive FTP connections in connecting state. It hurts
only IPVS connections.

	This patch changes the connection lookup for packets from
clients:

* introduce IP_VS_CONN_F_TEMPLATE connection flag to mark the
connection as template
* create new connection lookup function just for templates - ip_vs_ct_in_get
* make sure ip_vs_conn_in_get hits only connections with
IP_VS_CONN_F_NO_CPORT flag set when s_port is 0. By this way
we avoid returning template when looking for cport=0 (ftp)

[PATCH] 32bit sendmsg() flaw (CAN-2005-2490)

2005-09-10T02:42:53+00:00

When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.

Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areas

Another thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.

[PATCH] x86_64: Tell VM about holes in nodes

2005-08-27T02:37:12+00:00

Some nodes can have large holes on x86-64.

This fixes problems with the VM allowing too many dirty pages because it
overestimates the number of available RAM in a node.  In extreme cases you
can end up with all RAM filled with dirty pages which can lead to deadlocks
and other nasty behaviour.

This patch just tells the VM about the known holes from e820.  Reserved
(like the kernel text or mem_map) is still not taken into account, but that
should be only a few percent error now.

Small detail is that the flat setup uses the NUMA free_area_init_node() now
too because it offers more flexibility.

(akpm: lotsa thanks to Martin for working this problem out)

[PATCH] ppc64: Fix issue with gcc 4.0 compiled kernels

2005-08-27T02:37:11+00:00

I recently had a BUG_ON() go off spuriously on a gcc 4.0 compiled kernel.
It turns out gcc-4.0 was removing a sign extension while earlier gcc
versions would not.  Thinking this to be a compiler bug, I submitted a
report:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23422

It turns out we need to cast the input in order to tell gcc to sign extend
it.

Thanks to Andrew Pinski for his help on this bug.

[PATCH] Fix IXP4xx CLOCK_TICK_RATE

2005-08-24T03:06:33+00:00

As pointed out in the following thread, the CLOCK_TICK_RATE setting for
IXP4xx is incorrect b/c the HW ignores the lowest 2 bits of the LATCH
value.
