2008-09-26kgdb, x86, arm, mips, powerpc: ignore user space single steppingJason Wessel5-18/+18
On the x86 arch, user space single step exceptions should be ignored if they occur in the kernel space, such as ptrace stepping through a system call. First check if it is kgdb that is executing a single step, then ensure it is not an accidental traversal into the user space, while in kgdb, any other time the TIF_SINGLESTEP is set, kgdb should ignore the exception. On x86, arm, mips and powerpc, the kgdb_contthread usage was inconsistent with the way single stepping is implemented in the kgdb core. The arch specific stub should always set the kgdb_cpu_doing_single_step correctly if it is single stepping. This allows kgdb to correctly process an instruction steps if ptrace happens to be requesting an instruction step over a system call. Signed-off-by: Jason Wessel <[email protected]>

2008-09-26[XFS] Remove xfs_iext_irec_compact_full()Lachlan McIlroy1-92/+3
Yet another bug was found in xfs_iext_irec_compact_full() and while the source of the bug was found it wasn't an easy task to track it down because the conditions are very difficult to reproduce. A HUGE thank-you goes to Russell Cattelan and Eric Sandeen for their significant effort in tracking down the source of this corruption. xfs_iext_irec_compact_full() and xfs_iext_irec_compact_pages() are almost identical - they both compact indirect extent lists by moving extents from subsequent buffers into earlier ones. xfs_iext_irec_compact_pages() only moves extents if all of the extents in the next buffer will fit into the empty space in the buffer before it. xfs_iext_irec_compact_full() will go a step further and move part of the next buffer if all the extents wont fit. It will then shift the remaining extents in the next buffer up to the start of the buffer. The bug here was that we did not update er_extoff and this caused extent list corruption. It does not appear that this extra functionality gains us much. Calling xfs_iext_irec_compact_pages() instead will do a good enough job at compacting the indirect list and will be quicker too. For the case in xfs_iext_indirect_to_direct() the total number of extents in the indirect list will fit into one buffer so we will never need the extra functionality of xfs_iext_irec_compact_full() there. Also xfs_iext_irec_compact_pages() doesn't need to do a memmove() (the buffers will never overlap) so we don't want the performance hit that can incur.

2008-09-25IPoIB: Fix crash when path record fails after path flushRoland Dreier1-4/+4
Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") changed how paths are flushed on an SM event. This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

2008-09-249p-trans_fd: fix trans_fd::p9_conn_destroy()Tejun Heo1-19/+5
p9_conn_destroy() first kills all current requests by calling p9_conn_cancel(), then waits for the request list to be cleared by waiting on p9_conn->equeue. After that, polling is stopped and the trans is destroyed. This sequence has a few problems. * Read and write works were never cancelled and the p9_conn can be destroyed while the works are running as r/w works remove requests from the list and dereference the p9_conn from them. * The list emptiness wait using p9_conn->equeue wouldn't trigger because p9_conn_cancel() always clears all the lists and the only way the wait can be triggered is to have another task to issue a request between the slim window between p9_conn_cancel() and the wait, which isn't safe under the current implementation with or without the wait. This patch fixes the problem by first stopping poll, which can schedule r/w works, first and cancle r/w works which guarantees that r/w works are not and will not run from that point and then calling p9_conn_cancel() and do the rest of destruction.
