c80d471 Tim Abbott 26 April 2009, 02:10:56 UTC Add new HEAD_TEXT_SECTION macro. This patch is preparation for replacing all uses of ".head.text" or ".text.head" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. Since some linker scripts do more complex things than referencing HEAD_TEXT, we add a HEAD_TEXT_SECTION macro that just contains the actual name. I've defined HEAD_TEXT_SECTION in a new header, include/linux/section-names.h, so that this section name only needs to appear in one place. I anticipate creating similar macro structures for a number of other section names. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".text.foo".

0c8454f Rafael J. Wysocki 24 April 2009, 22:16:06 UTC PM/Hibernate: Fix waiting for image device to appear on resume Commit c751085943362143f84346d274e0011419c84202 ("PM/Hibernate: Wait for SCSI devices scan to complete during resume") added a call to scsi_complete_async_scans() to software_resume(), so that it waited for the SCSI scanning to complete, but the call was added at a wrong place. Namely, it should have been added after wait_for_device_probe(), which is called only if the image partition hasn't been specified yet. Also, it's reasonable to check if the image partition is present and only wait for the device probing and SCSI scanning to complete if it is not the case. Additionally, since noresume is checked right at the beginning of software_resume() and the function returns immediately if it's set, it doesn't make sense to check it once again later.

4b2b0b9 David Howells 23 April 2009, 15:41:18 UTC ROMFS: Advance destination buffer pointer when reading from a blockdev RomFS should advance the destination buffer pointer when reading data from a blockdev source (the data may be split over multiple blocks, each requiring its own sb_read() call). Without this, all the data is copied to the beginning of the output buffer.

84baf74 David Howells 23 April 2009, 15:41:13 UTC ROMFS: romfs_lookup() shouldn't be doing a partial name comparison romfs_lookup() should be using a routine akin to strcmp() on the backing store, rather than one akin to strncmp(). If it uses the latter, it's liable to match /bin/shutdown when looking up /bin/sh.

8c652f9 Oleg Nesterov 23 April 2009, 23:01:56 UTC do_execve() must not clear fs->in_exec if it was set by another thread If do_execve() fails after check_unsafe_exec(), it clears fs->in_exec unconditionally. This is wrong if we race with our sub-thread which also does do_execve: Two threads T1 and T2 and another process P, all share the same ->fs. T1 starts do_execve(BAD_FILE). It calls check_unsafe_exec(), since ->fs is shared, we set LSM_UNSAFE but not ->in_exec. P exits and decrements fs->users. T2 starts do_execve(), calls check_unsafe_exec(), now ->fs is not shared, we set fs->in_exec. T1 continues, open_exec(BAD_FILE) fails, we clear ->in_exec and return to the user-space. T1 does clone(CLONE_FS /* without CLONE_THREAD */). T2 continues without LSM_UNSAFE_SHARE while ->fs is shared with another process. Change check_unsafe_exec() to return res = 1 if we set ->in_exec, and change do_execve() to clear ->in_exec depending on res. When do_execve() suceeds, it is safe to clear ->in_exec unconditionally. It can be set only if we don't share ->fs with another process, and since we already killed all sub-threads either ->in_exec == 0 or we are the only user of this ->fs. Also, we do not need fs->lock to clear fs->in_exec.

f2d1f0a Jens Axboe 23 April 2009, 10:19:38 UTC cfq-iosched: cache prio_tree root in cfqq->p_root Currently we look it up from ->ioprio, but ->ioprio can change if either the process gets its IO priority changed explicitly, or if cfq decides to temporarily boost it. So if we are unlucky, we can end up attempting to remove a node from a different rbtree root than where it was added. Fix this by using ->org_ioprio as the prio_tree index, since that will only change for explicit IO priority settings (not for a boost). Additionally cache the rbtree root inside the cfqq, then we don't have to add code to reinsert the cfqq in the prio_tree if IO priority changes.

Fix that. cfq_prio_tree_add() assumes that we don't get a direct match, while it is very possible that we do. Using O_DIRECT, you can have different cfqq with matching requests, since you don't have the page cache to serialize things for you. Fix this bug by only adding the cfqq if there isn't an existing match. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> 24 April 2009, 06:54:22 UTC

17d5c8c Hannes Reinecke 23 April 2009, 08:32:59 UTC block: fix intermittent dm timeout based oops Very rarely under stress testing of dm, oopses are occuring as something tampers with an old stack frame. This has been traced back to blk_abort_queue() leaving a timeout_list pointing to the stack. The reason is that sometimes blk_abort_request() won't delete the timer (if the request is marked as complete but before the timer has been removed, a small race window). Fix this by splicing back from the ususally empty list to the q->timeout_list.

f3c737d Sage Weil 23 April 2009, 06:37:58 UTC umem: fix request_queue lock warning The umem driver issues two warnings on boot, due to blk_plug_device() and blk_remove_plug() being called without q->queue_lock held. Starting with e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock is NULL (though that apparently isn't otherwise a problem as the driver is using card->lock for everything). Although blk_init_queue() with take a request_fn_proc and spinlock_t*, there isn't a corresponding init helper that takes a make_request_fn. Setting queue_lock to &card->lock explicitly seems to work fine for me. The warning goes away and the device appears to behave.

But as of ff69f2bba67bd45514923aaedbf40fe351787c59 (acpi: fix of pmtimer overflow that make Cx states time incorrect) the HPET may be used via clocksource for idle accounting, and hpet=force on an ICH4 box hangs boot. It turns out that touching the MMIO HPET withing the ARB_DIS part of C3 will hang the hardware. The fix is to simply move the timer access outside the ARB_DIS region. This is a no-op on modern hardware because ARB_DIS is no longer used. http://bugzilla.kernel.org/show_bug.cgi?id=13087 Acked-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> 24 April 2009, 01:51:51 UTC

Since close_backing_file() prints a LUN's name for debugging, it shouldn't be called after the LUN has been unregistered.

The resulting schedule looks like this: uframe 0: 188-byte isoc-OUT SSPLIT, 8-byte int-IN SSPLIT uframe 1: 4-byte isoc-OUT SSPLIT The SSPLITs are intermingled, causing an error in the downstream hub's TT.

2d93148 Alan Stern 14 April 2009, 15:31:02 UTC USB: serial: fix lifetime and locking problems This patch (as1229) fixes a few lifetime and locking problems in the usb-serial driver. The main symptom is that an invalid kevent is created when the serial device is unplugged while a connection is active. Ports should be unregistered when device is disconnected, not when the parent usb_serial structure is deallocated. Each open file should hold a reference to the corresponding port structure, and the reference should be released when the file is closed. serial->disc_mutex should be acquired in serial_open(), to resolve the classic race between open and disconnect. serial_close() doesn't need to hold both serial->disc_mutex and port->mutex at the same time. Release the subdriver's module reference only after releasing all the other references, in case one of the release routines needs to invoke some code in the subdriver module. Replace a call to flush_scheduled_work() (which is prone to deadlocks) with cancel_work_sync(). Also, add a call to cancel_work_sync() in the disconnect routine. Reduce the scope of serial->disc_mutex in serial_disconnect(). The only place it really needs to protect is where the "disconnected" flag is set.
