15 years agomm: remove lru_add_drain_all() from the munlock path

mm: remove lru_add_drain_all() from the munlock path

lockdep warns about following message at boot time on one of my test
machine.  Then, schedule_on_each_cpu() sholdn't be called when the task
have mmap_sem.

Actually, lru_add_drain_all() exist to prevent the unevictalble pages
stay on reclaimable lru list.  but currenct unevictable code can rescue
unevictable pages although it stay on reclaimable list.

So removing is better.

In addition, this patch add lru_add_drain_all() to sys_mlock() and
sys_mlockall().  it isn't must.  but it reduce the failure of moving to
unevictable list.  its failure can rescue in vmscan later.  but reducing
is better.

Note, if above rescuing happend, the Mlocked and the Unevictable field
mismatching happend in /proc/meminfo.  but it doesn't cause any real
trouble.

hugetlb: make unmap_ref_private multi-size-aware

Oops.  Part of the hugetlb private reservation code was not fully
converted to use hstates.

When a huge page must be unmapped from VMAs due to a failed COW,
HPAGE_SIZE is used in the call to unmap_hugepage_range() regardless of
the page size being used.  This works if the VMA is using the default
huge page size.  Otherwise we might unmap too much, too little, or
trigger a BUG_ON.  Rare but serious -- fix it.

15 years agoniu: Fix readq implementation when architecture does not provide one.
David S. Miller [Wed, 12 Nov 2008 22:32:54 +0000 (14:32 -0800)]
niu: Fix readq implementation when architecture does not provide one.

This fixes a TX hang reported by Jesper Dangaard Brouer.

When an architecutre cannot provide a fully functional
64-bit atomic readq/writeq, the driver must implement
it's own.  This is because only the driver can say whether
doing something like using two 32-bit reads to implement
the full 64-bit read will actually work properly.

In particular one of the issues is whether the top 32-bits
or the bottom 32-bits of the 64-bit register should be read
first.  There could be side effects, and in fact that is
exactly the problem here.

The TX_CS register has counters in the upper 32-bits and
state bits in the lower 32-bits.  A read clears the state
bits.

We would read the counter half before the state bit half.
That first read would clear the state bits, and then the
driver thinks that no interrupts are pending because the
interrupt indication state bits are seen clear every time.

Fix this by reading the bottom half before the upper half.

hostap: pad the skb->cb usage in lieu of a proper fix

to the physical wireless device.  Unfortunately, that trick no longer
works...

Unlike mac80211, code complexity and driver apathy makes this hack
the best option we have in the short run.  Hopefully someone will
eventually be motivated to code a proper fix before all the effected

IPoIB: Fix crash in path_rec_completion()

Fix a crash in path_rec_completion() during an SM up/down loop.  If
more than one path record request is issued, the first completion
releases path->done, allowing ipoib_flush_paths() to free the path,
and thus corrupting it for the second completion.

Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM
change events") added the field path->valid and changed the test "if
(!path)" to "if (!path || !path->valid)".  This change made it
possible for a path with an outstanding query to pass the test and
issue another query on the same path.  Having two queries on the same
path leads to a crash.

RDMA/cxgb3: Fix deadlock in iw_cxgb3 (hang when configuring interface)

When the iw_cxgb3 module's cxgb3_client "add" func gets called by the
cxgb3 module, the iwarp driver ends up calling the ethtool ops
get_drvinfo function in cxgb3 to get the fw version and other info.
Currently the iwarp driver grabs the rtnl lock around this down call
to serialize.  As of 2.6.27 or so, things changed such that the rtnl
lock is held around the call to the netdev driver open function.  Also
the cxgb3_client "add" function doesn't get called if the device is
down.

So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the
device, the iw_cxgb3 add func gets called with the rtnl_lock held.  If
you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add
func gets called without the rtnl_lock held.  The former causes the
deadlock, the latter does not.

In addition, there are iw_cxgb3 sysfs handlers that also can call down
into cxgb3 to gather the fw and hw versions.  These can be called
concurrently on different processors and at any time.  Thus we need to
push this serialization down in the cxgb3 driver get_drvinfo func.

The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.
