[PATCH] Fix RTNLGRP definitions in rtnetlink.h

2005-12-27T00:08:57+00:00

I reported a problem and gave hints to the solution, but nobody seemed
to react. So I prepared a patch against 2.6.14.4.

Tested on 2.6.14.4 with "ip monitor addr" and with the program
attached, while adding and removing IPv6 address. Both programs didn't
receive any messages.  Tested 2.6.14.4 + this patch, and both programs
received add and remove messages.

[PATCH] cciss: bug fix for hpacucli

2005-12-14T23:43:00+00:00

From Mike Miller 

This patch fixes a bug that breaks hpacucli, a command line interface
for the HP Array Config Utility. Without this fix the utility will
not detect any controllers in the system. I thought I had already fixed
this, but I guess not.

Thanks to all who reported the issue. Please consider this this inclusion.

[PATCH] CVE-2005-2709 sysctl unregistration oops

2005-11-08T19:14:00+00:00

You could open the /proc/sys/net/ipv4/conf// file, then
wait for interface to go away, try to grab as much memory as possible in
hope to hit the (kfreed) ctl_table.  Then fill it with pointers to your
function. Then do read from file you've opened and if you are lucky,
you'll get it called as ->proc_handler() in kernel mode.

So this is at least an Oops and possibly more.  It does depend on an
interface going away though, so less of a security risk than it would
otherwise be.

[PATCH] inotify/idr leak fix

2005-10-23T23:38:39+00:00

Fix a bug which was reported and diagnosed by
Stefan Jones 

IDR trees include a cache of idr_layer objects.  There's no way to destroy
this cache, so when we discard an overall idr tree we end up leaking some
memory.

Add and use idr_destroy() for this.  v9fs and infiniband also need to use
idr_destroy() to avoid leaks.

Or, we make the cache global, like radix_tree_preload().  Which is probably
better.  Later.

[PATCH] Fix handling spurious page fault for hugetlb region

2005-10-20T16:02:07+00:00

This reverts commit 3359b54c8c07338f3a863d1109b42eebccdcf379 and
replaces it with a cleaner version that is purely based on page table
operations, so that the synchronization between inode size and hugetlb
mappings becomes moot.

[PATCH] swiotlb: make sure initial DMA allocations really are in DMA memory

2005-10-20T06:11:33+00:00

This introduces a limit parameter to the core bootmem allocator; The new
parameter indicates that physical memory allocated by the bootmem
allocator should be within the requested limit.

We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit,
alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit
is the only api used for swiotlb.

The existing alloc_bootmem_low_pages() api could instead have been
changed and made to pass right limit to the core allocator.  But that
would make the patch more intrusive for 2.6.14, as other arches use
alloc_bootmem_low_pages().  We may be done that post 2.6.14 as a
cleanup.

With this, swiotlb gets memory within 4G for both x86_64 and ia64
arches.

[PATCH] Handle spurious page fault for hugetlb region

2005-10-19T20:56:27+00:00

The hugetlb pages are currently pre-faulted.  At the time of mmap of
hugepages, we populate the new PTEs.  It is possible that HW has already
cached some of the unused PTEs internally.  These stale entries never
get a chance to be purged in existing control flow.

This patch extends the check in page fault code for hugepages.  Check if
a faulted address falls with in size for the hugetlb file backing it.
We return VM_FAULT_MINOR for these cases (assuming that the arch
specific page-faulting code purges the stale entry for the archs that
need it).

[ This is apparently arguably an ia64 port bug. But the code won't
  hurt, and for now it fixes a real problem on some ia64 machines ]

[PATCH] aio: revert lock_kiocb()

2005-10-18T00:03:57+00:00

lock_kiocb() was introduced to serialize retrying and cancellation.  In the
process of doing so it tried to sleep waiting for KIF_LOCKED while holding
the ctx_lock spinlock.  Recent fixes have ensured that multiple concurrent
retries won't be attempted for a given iocb.  Cancel has other problems and
has no significant in-tree users that have been complaining about it.  So
for the immediate future we'll revert sleeping with the lock held and will
address proper cancellation and retry serialization in the future.
