NFS: More page cache revalidation fixups

2006-10-13T18:50:10+00:00

Whenever the directory changes, we want to make sure that we always
invalidate its page cache. Fix up update_changeattr() and
nfs_mark_for_revalidate() so that they do so.

SUNRPC: avoid choosing an IPMI port for RPC traffic

2006-10-13T18:50:10+00:00

Some hardware uses port 664 for its hardware-based IPMI listener.  Teach
the RPC client to avoid using that port by raising the default minimum port
number to 665.

Test plan:
Find a mainboard known to use port 664 for IPMI; enable IPMI; mount NFS
servers in a tight loop.

[PATCH] lib: add idr_replace

2006-09-09T03:23:01+00:00

This patch adds idr_replace() to replace an existing pointer in a single
operation.

Device-mapper will use this to update the pointer it stored against a given
id.

bridge-netfilter: don't overwrite memory outside of skb

2006-09-08T21:51:37+00:00

The bridge netfilter code needs to check for space at the
front of the skb before overwriting; otherwise if skb from
device doesn't have headroom, then it will cause random
memory corruption.

Fix output framentation of paged-skbs

2006-09-08T21:51:36+00:00

[INET]: Use pskb_trim_unique when trimming paged unique skbs

The IPv4/IPv6 datagram output path was using skb_trim to trim paged
packets because they know that the packet has not been cloned yet
(since the packet hasn't been given to anything else in the system).

This broke because skb_trim no longer allows paged packets to be
trimmed.  Paged packets must be given to one of the pskb_trim functions
instead.

This patch adds a new pskb_trim_unique function to cover the IPv4/IPv6
datagram output path scenario and replaces the corresponding skb_trim
calls with it.

ext3: avoid triggering ext3_error on bad NFS file handle

2006-08-07T03:52:15+00:00

The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking.  If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.

So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

Update frag_list in pskb_trim

2006-08-07T03:52:14+00:00

[NET]: Update frag_list in pskb_trim

When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming.  This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.

Examples include esp_output and ip_fragment.

Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.

It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list.  In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb.  For now though, let's do the conservative fix
and update frag_list.

Many thanks to Marco Berizzi for helping me to track down this bug.

This 4-year old bug took 3 months to track down.  Marco was very patient
indeed :)
