7472f38 David Brownell 19 April 2008, 01:47:54 UTC usb: gadget zero style fixups (mostly whitespace) Minor updates to "Gadget Zero". - Primarily these are whitespace updates to address the fact that since this was written, Documentation/CodingStyle was changed to disapprove of parts of the original coding style. - Update a few comments that weren't quite correct, notably mentioning the "autoresume" module parameter.

f371e75 David Brownell 19 April 2008, 00:37:49 UTC usb serial gadget: CDC ACM fixes Based on a patch from <Aurel.Thomi@ruag.com>, this makes the CDC-ACM support in the serial gadget handle the SET_LINE_CODING and SET_CONTROL_LINE_STATE requests ... which should improve interop with at least MS-Windows "usbser.sys" if not some other ACM host drivers. It also adds a few REVISIT comments where this code plays a bit loose with the CDC ACM spec. If this were used to hook up to a real RS232 or modem link, those places would need a bit of work.

d75379a Robert Jarzmik 18 April 2008, 22:56:49 UTC usb: pxa27x_udc driver Adds pxa27x udc driver to support USB peripherals on pxa27x chips. The driver is compatible with: Gadget Zero, the File Storage gadget, and the Ethernet gadget (only in CDC subset mode). The driver can't properly support multiple interfaces, because of hardware bugs without possible workaround. That means no RNDIS support from g_ether, and no CDC ACM support in g_serial.

28ffd79 David Brownell 26 April 2008, 01:51:10 UTC USB: usbtest displays diagnostics again Minor cleanup to the "usbtest" driver, mostly to resolve a regression: all the important diagnostics were at KERN_DEBUG, so that when the "#define DEBUG" was removed from the top of that file it stopped providing diagnostics. Fix by using KERN_ERROR. Also: - Stop using the legacy dbg() calls - Simplify the internal debug macros - Correct some test descriptions: * Test #10 subcase 7 should *always* stall * Test #10 subcase 8 *may* stall - Diagnostic about control queue test failures is more informative - Fix some whitespace "bugs" And add a warning about the rude interaction between usbfs ioctl() and khubd during device disconnect ... don't unplug a device under test, that will wedge.

2d7f16d Wilson Callan 01 May 2008, 02:16:28 UTC m68knommu: fix signal handling return path The return from software signal handling pushes code on the stack that system calls to the kernels cleanup code. This is borrowed directly from the m68k linux signal handler. The rt signal case is not quite right for the restricted instruction set of the ColdFire parts.

Rework the return path to just call back through some code fragments in the kernel proper (with no MMU in the way we can do this). No cache problems, and less code overall.

9d2de6a Jeff Moyer 01 May 2008, 11:35:09 UTC autofs4: fix incorrect return from root.c:try_to_fill_dentry() Jeff Moyer has identified a case where the autofs4 function root.c:try_to_fill_dentry() can return -EBUSY when it should return 0. Jeff's description of the way this happens is: "automount starts an expire for directory d. after the callout to the daemon, but before the rmdir, another process tries to walk into the same directory. It puts itself onto the waitq, pending the expiration. When the expire finishes, the second process is woken up. In try_to_fill_dentry, it does this check: status = d_invalidate(dentry); if (status != -EBUSY) return -EAGAIN; And status is EBUSY. The dentry still has a non-zero d_inode, and the flags do not contain LOOKUP_CONTINUE or LOOKUP_DIRECTORY So, we fall through and return -EBUSY to the caller."

0337904 Jeff Moyer 01 May 2008, 11:35:08 UTC autofs4: fix execution order race in mount request code Jeff Moyer has identified a race in due to an execution order dependency in the autofs4 function root.c:try_to_fill_dentry(). Jeff's description of this race is: "P1 does a lookup of /mount/submount/foo. Since the VFS can't find an entry for "foo" under /mount/submount, it calls into the autofs4 kernel module to allocate a new dentry, D1. The kernel creates a new waitq for this lookup and calls the daemon to perform the mount. The daemon performs a mkdir of the "foo" directory under /mount/submount, which ends up creating a *new* dentry, D2. Then, P2 does a lookup of /mount/submount/foo. The VFS path walking logic finds a dentry in the dcache, D2, and calls the revalidate function with this. In the autofs4 revalidate code, we then trigger a mount, since the dentry is an empty directory that isn't a mountpoint, and so set DCACHE_AUTOFS_PENDING and call into the wait code to trigger the mount. The wait code finds our existing waitq entry (since it is keyed off of the directory name) and adds itself to the list of waiters. After the daemon finishes the mount, it calls back into the kernel to release the waiters. When this happens, P1 is woken up and goes about clearing the DCACHE_AUTOFS_PENDING flag, but it does this in D1! So, given that P1 in our case is a program that will immediately try to access a file under /mount/submount/foo, we end up finding the dentry D2 which still has the pending flag set, and we set out to wait for a mount *again*! So, one way to address this is to re-do the lookup at the end of try_to_fill_dentry, and to clear the pending flag on the hashed dentry. This seems a sane approach to me." And Jeff's patch does this.

be089d7 Michael Ellerman 01 May 2008, 11:34:49 UTC kexec: make extended crashkernel= syntax less confusing The extended crashkernel syntax is a little confusing in the way it handles ranges. eg: crashkernel=512M-2G:64M,2G-:128M Means if the machine has between 512M and 2G of memory the crash region should be 64M, and if the machine has 2G of memory the region should be 64M. Only if the machine has more than 2G memory will 128M be allocated. Although that semantic is correct, it is somewhat baffling. Instead I propose that the end of the range means the first address past the end of the range, ie: 512M up to but not including 2G.

02c6be6 Miklos Szeredi 01 May 2008, 11:34:45 UTC vfs: fix permission checking in sys_utimensat If utimensat() is called with both times set to UTIME_NOW or one of them to UTIME_NOW and the other to UTIME_OMIT, then it will update the file time without any permission checking. I don't think this can be used for anything other than a local DoS, but could be quite bewildering at that (e.g. "Why was that large source tree rebuilt when I didn't modify anything???") This affects all kernels from 2.6.22, when the utimensat() syscall was introduced. Fix by doing the same permission checking as for the "times == NULL" case. Thanks to Michael Kerrisk, whose utimensat-non-conformances-and-fixes.patch in -mm also fixes this (and breaks other stuff), only he didn't realize the security implications of this bug.

34990cf David Brownell 01 May 2008, 11:34:42 UTC Add a new sysfs_streq() string comparison function Add a new sysfs_streq() string comparison function, which ignores the trailing newlines found in sysfs inputs. By example: sysfs_streq("a", "b") ==> false sysfs_streq("a", "a") ==> true sysfs_streq("a", "a\n") ==> true sysfs_streq("a\n", "a") ==> true This is intended to simplify parsing of sysfs inputs, letting them avoid the need to manually strip off newlines from inputs.

7dffa3c Roman Zippel 01 May 2008, 11:34:41 UTC ntp: handle leap second via timer Remove the leap second handling from second_overflow(), which doesn't have to check for it every second anymore. With CONFIG_NO_HZ this also makes sure the leap second is handled close to the full second. Additionally this makes it possible to abort a leap second properly by resetting the STA_INS/STA_DEL status bits.

9f14f66 Roman Zippel 01 May 2008, 11:34:36 UTC ntp: increase time_offset resolution time_offset is already a 64bit value but its resolution barely used, so this makes better use of it by replacing SHIFT_UPDATE with TICK_LENGTH_SHIFT. Side note: the SHIFT_HZ in SHIFT_UPDATE was incorrect for CONFIG_NO_HZ and the primary reason for changing time_offset to 64bit to avoid the overflow.

074b3b8 Roman Zippel 01 May 2008, 11:34:34 UTC ntp: increase time_freq resolution This changes time_freq to a 64bit value and makes it static (the only outside user had no real need to modify it). Intermediate values were already 64bit, so the change isn't that big, but it saves a little in shifts by replacing SHIFT_NSEC with TICK_LENGTH_SHIFT. PPM_SCALE is then used to convert between user space and kernel space representation.

eea83d8 Roman Zippel 01 May 2008, 11:34:33 UTC ntp: NTP4 user space bits update This adds a few more things from the ntp nanokernel related to user space. It's now possible to select the resolution used of some values via STA_NANO and the kernel reports in which mode it works (pll/fll). If some values for adjtimex() are outside the acceptable range, they are now simply normalized instead of letting the syscall fail. I removed MOD_CLKA/MOD_CLKB as the mapping didn't really makes any sense, the kernel doesn't support setting the clock.

f8bd225 Roman Zippel 01 May 2008, 11:34:31 UTC remove div_long_long_rem x86 is the only arch right now, which provides an optimized for div_long_long_rem and it has the downside that one has to be very careful that the divide doesn't overflow. The API is a little akward, as the arguments for the unsigned divide are signed. The signed version also doesn't handle a negative divisor and produces worse code on 64bit archs. There is little incentive to keep this API alive, so this converts the few users to the new API.

Move its definition to math64.h as currently no architecture overrides the generic implementation. They can still override it of course, but the duplicated declarations are avoided.

2418f4f Roman Zippel 01 May 2008, 11:34:25 UTC introduce explicit signed/unsigned 64bit divide The current do_div doesn't explicitly say that it's unsigned and the signed counterpart is missing, which is e.g. needed when dealing with time values. This introduces 64bit signed/unsigned divide functions which also attempts to cleanup the somewhat awkward calling API, which often requires the use of temporary variables for the dividend. To avoid the need for temporary variables everywhere for the remainder, each divide variant also provides a version which doesn't return the remainder. Each architecture can now provide optimized versions of these function, otherwise generic fallback implementations will be used. As an example I provided an alternative for the current x86 divide, which avoids the asm casts and using an union allows gcc to generate better code. It also avoids the upper divde in a few more cases, where the result is known (i.e. upper quotient is zero).
