[PATCH] ib: mthca: Always re-arm EQs in mthca_tavor_interrupt()

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

We should always re-arm an event queue's interrupt in
mthca_tavor_interrupt() if the corresponding bit is set in the event cause
register (ECR), even if we didn't find any entries in the EQ.  If we don't,
then there's a window where we miss an EQ entry and then get stuck because
we don't get another EQ event.

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

[IPoIB] Rename IPoIB's path_lookup() to avoid name clashes

2005-09-29T02:56:57+00:00

Rename IPoIB driver's path_lookup() to ipoib_path_lookup() to avoid a
clashes with the kernel global path_lookup().  We don't hit this with
the current kernel source, but some external patches seem to trigger
this, and it's cleaner to avoid clashing with global names anyway.

[IB] mthca: Round up number of slots in HCA context memory table

2005-09-27T04:12:26+00:00

When allocating a table for mem-free HCA context, don't assume that
obj_size * nobj is an even multiple of MTHCA_TABLE_CHUNK_SIZE.  In
particular, make sure we allocate at least one slot even if the table
is smaller than MTHCA_TABLE_CHUNK_SIZE.

[IB] uverbs: Close some exploitable races

2005-09-26T20:01:03+00:00

Al Viro pointed out that the current IB userspace verbs interface
allows userspace to cause mischief by closing file descriptors before
we're ready, or issuing the same command twice at the same time.  This
patch closes those races, and fixes other obvious problems such as a
module reference leak.

Some other interface bogosities will require an ABI change to fix
properly, so I'm deferring those fixes until 2.6.15.

The loop in mthca_map_cmd() would fill one entry past the end of the
mailbox buffer before calling the firmware command.

[IB] mthca: fix off by one in clr_int calculation

2005-09-26T16:38:34+00:00

We should use the first word of the clear interrupt register if
the bit we're after is < 32, not < 31.

[IB] mthca: Fix doorbell record resource leak

2005-09-26T16:38:26+00:00

If we allocate a bunch of doorbell records and then free them, we'll
end up with completely empty pages, which we then free.  However, when
we come back to allocate more doorbell pages, we have to reallocate
those empty pages rather than always trying to take a slot that we've
never used.  If we don't, we eventually use up every slot and fail to
allocate a doorbell record, even though we have plenty of free space.
