2007-12-17ecryptfs: initialize new auth_tokens before teardownEric Sandeen1-1/+1
ecryptfs_destroy_mount_crypt_stat() checks whether each auth_tok->global_auth_tok_key is nonzero and if so puts that key. However, in some early mount error paths nothing has initialized the pointer, and we try to key_put() garbage. Running the bad cipher tests in the testsuite exposes this, and it's happy with the following change.

2007-12-17parport: "dev->timeslice" is an unsigned long, not an intEric Dumazet1-1/+1
While auditing proc_doulongvec_ms_jiffies_minmax() usage in kernel, I found a bug in drivers/parport/procfs.c, incorrectly using sizeof(int) instead of sizeof(unsigned long) Only 64bit arches are affected by this old bug.

2007-12-17alpha: strncpy/strncat fixesIvan Kokshaysky3-15/+15
First of all, thanks to Bob Tracy <rct@frus.com> and Michael Cree <mcree@orcon.net.nz> for testing. Especially to Bob, as he has done titanic multi-day git-bisect work that finally helped to reproduce and nail down the bug (http://bugzilla.kernel.org/show_bug.cgi?id=9457). [ev6-]stxncpy.S: it's t12, not t2 register that is supposed to contain the last byte offset upon return. As a result of wrong register use (which was my fault back in 2003, IIRC), under some circumstances extra terminating zero bytes were added to destination string. This particularly led to incorrect DEVPATH strings generated in uevent and therefore to udev problems. strncpy.S: unrelated bug I found while testing the above fix - destination is not properly zero-padded then a byte count exceeds source length. Actually this is addition to strncpy fix from last year.

2007-12-17uml: stop gdb from deleting breakpoints when running UMLStanislaw Gruszka12-56/+50
Sometimes when UML is debugged gdb miss breakpoints. When process traced by gdb do fork, debugger remove breakpoints from child address space. There is possibility to trace more than one fork, but this not work with UML, I guess (only guess) there is a deadlock - gdb waits for UML and UML waits for gdb. When clone() is called with SIGCHLD and CLONE_VM flags, gdb see this as PTRACE_EVENT_FORK not as PTRACE_EVENT_CLONE and remove breakpoints from child and at the same time from traced process, because either have the same address space. Maybe it is possible to do fix in gdb, but I'm not sure if there is easy way to find out if traced and child processes share memory. So I do fix for UML, it simply do not call clone() with both SIGCHLD and CLONE_VM flags together. Additionally __WALL flag is used for waitpid() to assure not miss clone and normal process events.

2007-12-17ocfs2: Re-journal buffers after transaction extendMark Fasheh2-21/+51
ocfs2_extend_trans() might call journal_restart() which will commit dirty buffers and then restart the transaction. This means that any buffers which still need changes should be passed to journal_access() again. Some paths during extend weren't doing this right. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2007-12-17ocfs2: Allow for debugging of transaction extendsMark Fasheh1-0/+4
The nastiest cases of transaction extends are also the rarest. We can expose them more quickly at the expense of performance by going straight to the journal_restart() in ocfs2_extend_trans(). Wrap things in OCFS2_DEBUG_FS so that we only do this when "expensive debugging" is turned on. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2007-12-17USB: revert portions of "UNUSUAL_DEV: Sync up some reported devices from Ubuntu"Greg Kroah-Hartman1-8/+0
This reverts one change from 67fa10627ec0d8aa16f1cf38cf527e67d8097d3c that prevented userspace from seing the "driver disk" lun in a san disk device. The kernel shouldn't do this, it's up to userspace to handle this properly, if it somehow wants to filter this away.

2007-12-17usb: Remove broken optimisation in OHCI IRQ handlerBenjamin Herrenschmidt1-10/+13
The OHCI IRQ handler has an optimisation that avoids reading some chip registers when the controller reports that the interrupt was triggered *only* because completed requests were written into the controller's "done list" and handed to the host. This mechanism can't be used on some controllers. Among others, it fails for the SA1111 and the AMCC 440EP PowerPC processor. This patch removes the optimisation and makes the code clearer.

2007-12-17USB: at91_udc: correct hanging while disconnecting usb cableNicolas Ferre1-0/+2
Correct hanging while disconnecting the USB device cable. Prevent a race between vbus and UDP interrupts. This bug was tracked on at91sam9260ek boards. A usb resume interrupt was firing after the vbus interrupt : the IP was then already stoped and not able to deal with it (no more clock). A simple interrupt disabling is ok as the "end of bus reset" irq is non maskable and ok to resume the USB device IP.

2007-12-17USB: use IRQF_DISABLED for HCD interrupt handlersAlan Stern6-10/+9
Host controller IRQs are supposed to be serviced with interrupts disabled. This patch (as1026) adds an IRQF_DISABLED flag to all the controller drivers that lack it. It also replaces the spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq() with simple spin_lock() and spin_unlock(). This fixes Bugzilla #9335.

This adds a device ID for the Aerocomm Radio Modem, which uses the cp2102. I'm sure changing num_bulk_in/num_bulk_out to NUM_DONT_CARE is the wrong fix, but this is the only device I have with a cp2102, so I have no idea what a good global value would be, if there is one.

2007-12-17usb-storage: Fix devices that cannot handle 32k transfersDoug Maxey3-4/+20
When a device cannot handle the smallest previously limited transfer size (64 blocks) without stalling, limit the device to the amount of packets that fit in a platform native page. The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever used on a platform that has larger than 8K pages, you lose unless you can convince the device firmware folks to fix the issue.
