The attached patch fixes endian issues in asix_tx_fixup() that prevented AX88772 and AX88178 devices from working on big-endian systems. With the attached patch, all three chips are reported to work on big endian. Signed-off-by:

This patch (as849) fixes a bug in the USB hub driver. A single pre-allocated buffer is used for all port status reads, but nothing guarantees exclusive use of the buffer. A mutex is added to provide this guarantee. Signed-off-by:

Fix up the error processing path: in usb_submit_urb failed, we forgot to free buffers. Also, don't free buffers in read callback: less error prone, 21 LOC less, no need to comment so much. N.B. write path is ok to do kfree. Signed-off-by:

usb: descriptor structures have to be packed Many of the Wireless USB decriptors added to usb_ch9.h don't have the __attribute__((packed)) tag, and thus, they don't reflect the wire size. This patch fixes that. Signed-off-by:

This patch (as848) adds a useful little debugging message to let us know when ehci-hcd's bus_suspend method runs. The other HCDs have similar messages; now ehci-hcd doesn't need to feel left out. Signed-off-by:

This patch (as847) makes some small changes to the hub driver's suspend method: For root hubs, the status URB should be unlinked and other activity stopped _before_ the bus_suspend method is called. The test for hdev->bus being NULL has been removed, since it can never succeed. Signed-off-by:

I added two fields to struct usb_serial_port to keep track of the throttle state. Other usb-serial drivers typically use private data for such things, but the generic driver can not really do that because some of its code is also used by other drivers (which may have their own private data needs). As it is, I am not sure that this patch is useful in all scenarios. It is certainly helpful for low-bandwidth devices that can hold their data in response to throttling. But for devices that pump data in real-time as fast as possible (webcam, A/D converter, etc), throttling may actually cause more data loss.

in devices.c we have a piece of code for dealing with losing in a race. If we indeed lose the race we don't care whether our own memory allocation worked. The check for that is so early that we return early even if we don't have to. Signed-off-by:

A simple driver to turn on the charging capability of a USB BlackBerry device when it is plugged into the machine. It does not bind to the device, so all userspace programs can still sync properly with it. Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this device as the power to the port will be shut down. This device id will have to be added to the global blacklist table when it is created. Signed-off-by: -

This patch (as850b) disables remote wakeup (and everything else!) on all EHCI ports when the shutdown() method is called. If remote wakeup is left active then some systems will reboot instead of powering off. This fixes Bugzilla #7828. Signed-off-by:

eCryptfs is gobbling a lot of stack in ecryptfs_generate_key_packet_set() because it allocates a temporary memory-hungry ecryptfs_key_record struct. This patch introduces a new kmem_cache for that struct and converts ecryptfs_generate_key_packet_set() to use it. Signed-off-by:

When NFSD receives a write request, the data is typically in a number of 1448 byte segments and writev is used to collect them together. Unfortunately, generic_file_buffered_write passes these to the filesystem one at a time, so an e.g. 32K over-write becomes a series of partial-page writes to each page, causing the filesystem to have to pre-read those pages - wasted effort. generic_file_buffered_write handles one segment of the vector at a time as it has to pre-fault in each segment to avoid deadlocks. When writing from kernel-space (and nfsd does) this is not an issue, so generic_file_buffered_write does not need to break and iovec from nfsd into little pieces. This patch avoids the splitting when get_fs is KERNEL_DS as it is from NFSd. This issue was introduced by commit 6527c2bdAcked-by:

When setting an ACL that lacks inheritable ACEs on a directory, we should set a default ACL of zero length, not a default ACL with all bits denied. Signed-off-by:

We're inserting deny's between some ACEs in order to enforce posix draft acl semantics which prevent permissions from accumulating across entries in an acl. That's fine, but we're doing that by inserting a deny after *every* allow, which is overkill. We shouldn't be adding them in places where they actually make no difference. Also replaced some helper functions for creating acl entries; I prefer just assigning directly to the struct fields--it takes a few more lines, but the field names provide some documentation that I think makes the result easier understand.

Return just the effective permissions, and forget about the mask. It isn't worth the complexity. WARNING: This breaks backwards compatibility with overly-picky nfsv4->posix acl translation, as may has been included in some patched versions of libacl.

The code that splits an incoming nfsv4 ACL into inheritable and effective parts can be combined with the the code that translates each to a posix acl, resulting in simpler code that requires one less pass through the ACL. Signed-off-by:

J. Bruce Fields authored
The rfc allows us to be more permissive about the ACL inheritance bits we accept: "If the server supports a single "inherit ACE" flag that applies to both files and directories, the server may reject the request (i.e., requiring the client to set both the file and directory inheritance flags). The server may also accept the request and silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag." Let's take the latter option--the ACL is a complex attribute that could be rejected for a wide variety of reasons, and the protocol gives us little ability to explain the reason for the rejection, so erroring out is a user-unfriendly last resort.

The server name is expected to be a null-terminated string, so we can't pass in the raw client identifier. What's more, the client identifier is just a binary, not necessarily printable, blob. Let's just use the ip address instead. The server name appears to exist just to help debugging by making some printk's more informative. Note that the string is copies into the rpc client structure, so the pointer to the local variable does not outlive the function call. Signed-off-by:

Ingo Molnar authored
Never mask interrupts immediately upon request. Disabling interrupts in high-performance codepaths is rare, and on the other hand this change could recover lost edges (or even other types of lost interrupts) by conservatively only masking interrupts after they happen. (NOTE: with this change the highlevel irq-disable code still soft-disables this IRQ line - and if such an interrupt happens then the IRQ flow handler keeps the IRQ masked.) Mark i8529A controllers as 'never loses an edge'. Signed-off-by:

Use RCU to avoid the need to acquire tasklist_lock in the single-threaded case of clock_gettime(). It still acquires tasklist_lock when for a (potentially multithreaded) process. This change allows realtime applications to frequently monitor CPU consumption of individual tasks, as requested (and now deployed) by some off-list users. This has been in Ingo Molnar's -rt patchset since late 2005 with no problems reported, and tests successfully on 2.6.20-rc6, so I believe that it is long-since ready for mainline adoption.
