2009-10-14sysfs: Allow sysfs_notify_dirent to be called from interrupt context.Neil Brown
sysfs_notify_dirent is a simple atomic operation that can be used to alert user-space that new data can be read from a sysfs attribute. Unfortunately it cannot currently be called from non-process context because of its use of spin_lock which is sometimes taken with interrupts enabled. So change all lockers of sysfs_open_dirent_lock to disable interrupts, thus making sysfs_notify_dirent safe to be called from non-process context (as drivers/md does in md_safemode_timeout). sysfs_get_open_dirent is (documented as being) only called from process context, so it uses spin_lock_irq. Other places use spin_lock_irqsave. The usage for sysfs_notify_dirent in md_safemode_timeout was introduced in 2.6.28, so this patch is suitable for that and more recent kernels.

2009-10-14tty: use the new 'flush_delayed_work()' helper to do ldisc flushLinus Torvalds
This way all flush_to_ldisc work is always done through the workqueues, and we thus have a single point of serialization. It also means that we can avoid calling flush_to_ldisc() entirely if there was no delayed work pending. [ Side note: using workqueues and keventd as the single way to enter flush_to_ldisc() still doesn't absolutely guarantee that we can't have concurrency: keventd is multithreaded and has a thread per CPU, and while the WORK_STRUCT_PENDING bit guarantees a single work only being on the pending list once, the work might be both pending and _running_ at the same time. Workqueues are not simple. ] This was also confirmed to fix bugzilla #14388, even without the earlier locking fix and cleanup (commit c8e331419: "tty: Make flush_to_ldisc() locking more robust"). So both commits fix the same bug differently, and either would have worked on its own. But I'm committing them both since they are cleanups independent of each other.

2009-10-14net/fec_mpc52xx: Fix kernel panic on FEC errorJohn Bonesio
The MDIO bus cannot be accessed at interrupt context, but on an FEC error, the fec_mpc52xx driver reset function also tries to reset the PHY. Since the error is detected at IRQ context, and the PHY functions try to sleep, the kernel ends up panicking. Resetting the PHY on an FEC error isn't even necessary. This patch solves the problem by removing the PHY reset entirely. Signed-off-by: John Bonesio <bones@secretlab.ca> Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David S.

2009-10-14tty: Make flush_to_ldisc() locking more robustLinus Torvalds
The locking logic in this function is extremely subtle, and it broke when we started doing potentially concurrent 'flush_to_ldisc()' calls in commit e043e42bdb66885b3ac10d27a01ccb9972e2b0a3 ("pty: avoid forcing 'low_latency' tty flag"). The code in flush_to_ldisc() used to set 'tty->buf.head' to NULL, with the intention that this would then cause any other concurrent calls to not do anything (locking note: we have to drop the buf.lock over the call to ->receive_buf that can block, which is why we can have concurrency here at all in the first place). It also used to set the TTY_FLUSHING bit, which would then cause any concurrent 'tty_buffer_flush()' to not free all the tty buffers and clear 'tty->buf.tail'. And with 'buf.head' being NULL, and 'buf.tail' being non-NULL, new data would never touch 'buf.head'. Does that sound a bit too subtle? It was. If another concurrent call to 'flush_to_ldisc()' were to come in, the NULL buf.head would indeed cause it to not process the buffer list, but it would still clear TTY_FLUSHING afterwards, making the buffer protection against 'tty_buffer_flush()' no longer work. So this clears it all up. We depend purely on TTY_FLUSHING for handling re-entrancy, and stop playing games with the buffer list entirely. In fact, the buffer list handling is now robust enough that we could probably stop doing the whole "protect against 'tty_buffer_flush()'" thing entirely. However, Alan also points out that we would probably be better off simplifying the locking even further, and just take the tty ldisc_mutex around all the buffer flushing calls. That seems like a good idea, but in the meantime this is a conceptually minimal fix (with the patch itself being bigger than required just to clean the code up and make it readable).

2009-10-14usb-storage: Workaround devices with bogus sense sizeBenjamin Herrenschmidt
usb-storage: Workaround devices with bogus sense size Some devices, such as Huawei E169, advertise more than the standard amount of sense data, causing us to set US_FL_SANE_SENSE, assuming they support it. However, they subsequently fail the request sense with that size. This works around it generically. When a sense request fails due to a device returning an error, US_FL_SANE_SENSE was set, and that sense request used a larger sense size, we retry with a smaller size before giving up.

When the EHCI driver falls behind in its scheduling, the active stream's first empty microframe may be in the past with respect to the current microframe. The code attempts to move the starting microframe ("start") N number of microframes forward, where N is the interval of endpoint. However, stream->interval is a copy of the endpoint's bInterval, which is designated in frames for FS devices, and microframes for HS devices. Convert stream->interval to microframes before using it to move the starting microframe forward.

The Unit_Characteristics entry of an SBP-2 unit directory is not mandatory as far as I can tell. If it is missing, we would probably fail to log in into the target because firewire-sbp2 would not wait for status after it sent the login request. The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it is executed exactly once before login, rather than 0..n times depending on the target's config ROM.
