| | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the CS4270 ALSA device driver to use the new-style I2C interface. Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the device trees can no longer be probed by old-style I2C drivers. The device tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since 2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem. Since that's no longer the case, the best solution is to update the CS4270 driver to a new-style interface, rather than try to revert the behavior of new PowerPC I2C subsystem.

| * | [SCSI] qlogicpti: fix sg list traversal error in continuation entriesBoaz Harrosh2008-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current sg list traversal logic for the continuation entries doesn't advance the list pointer once all seven slots are used, so the next continuation entry (if there is one) wrongly begins again at the start of the sg list. Fix by advancing the sg pointer after the for_each_sg().

| * | [SCSI] Fix hang with split requestsJames Bottomley2008-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes, particularly for USB devices with the last sector bug, requests get completed in chunks. There's a bug in this in that if one of the chunks gets an error, we complete that chunk with an error but never move on to the remaining ones, leading to the request hanging (because it's not fully completed). Fix this by completing all remaining chunks if an error is encountered. Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

Josip Rodin noted (http://article.gmane.org/gmane.linux.ports.sparc/10152) the driver oopsing during registration of an rport to the FC-transport layer with a backtrace indicating a dereferencing of an shost->shost_data equal to NULL. David Miller identified a small window in driver logic where this could happen: > Look at how the driver registers the IRQ handler before the host has > been registered with the SCSI layer. > > That leads to a window of time where the shost hasn't been setup > fully, yet ISRs can come in and trigger DPC thread events, such as > loop resyncs, which expect the transport area to be setup. > > But it won't be setup, because scsi_add_host() hasn't finished yet. > > Note that in Josip's crash log, we don't even see the > > qla_printk(KERN_INFO, ha, "\n" > " QLogic Fibre Channel HBA Driver: %s\n" > " QLogic %s - %s\n" > " ISP%04X: %s @ %s hdma%c, host#=%ld, fw=%s\n", > ... > > message yet. > > Which means that the crash occurs between qla2x00_request_irqs() > and printing that message.

* | | | Fix NULL pointer dereference in proc_sys_compareLinus Torvalds2008-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The VFS interface for the 'd_compare()' is a bit special (read: 'odd'), because it really just essentially replaces a memcmp(). The filesystem is supposed to just compare the two names with whatever case-independent or other function. And when I say 'is supposed to', I obviously mean that 'procfs does odd things, and actually looks at the dentry that we don't even pass down, rather than just the name'. Which results in problems, because we actually call d_compare before we have even verified that the dentry is still hashed at all. And that causes a problm since the inode that procfs looks at may have been free'd and the d_inode pointer is NULL. procfs just assumes that all dentries are positive, since procfs itself never generates a negative one. But memory pressure will still result in the dentry getting torn down, and as it is removed by RCU, it still remains visible on some lists - and to d_compare. If the filesystem just did a name comparison, we wouldn't care. And we could just fix procfs to know about negative dentries too. But rather than have the low-level filesystems know about internal VFS details, just move the check for a unhashed dentry up a bit, so that we will only call d_compare on dentries that are still active. The actual oops this caused didn't look like a NULL pointer dereference because procfs did a 'container_of(inode, struct proc_inode, vfs_inode)' to get at its internal proc_inode information from the inode pointer, and accessed a field below the inode. So the oops would look something like BUG: unable to handle kernel paging request at fffffffffffffff0 IP: [<ffffffff802bc6c6>] proc_sys_compare+0x36/0x50 and was seen on both x86-64 (Alexey Dobriyan and Hugh Dickins) and ppc64 (Hugh Dickins).

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.

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.

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newer MacBooks contain a Broadcom based Bluetooth chip and to make this work properly, HCI_Reset must be send first. If HCI_Reset is not used then a lot of I/O errors show up and its triggers packets from non-existent ACL links. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

For exeample, if we use 16KB page size the PGDIR_SHIFT is (14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be: 2^32/2^26 = 2^6 but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0). So, this definition needs to be consistent with the PGDIR_SIZE. And the new definition is consistent with the PGD init in pagetable_init().
