2008-01-13knfsd: Allow NFSv2/3 WRITE calls to succeed when krb5i etc is used.NeilBrown
When RPCSEC/GSS and krb5i is used, requests are padded, typically to a multiple of 8 bytes. This can make the request look slightly longer than it really is. As of f34b95689d2ce001c "The NFSv2/NFSv3 server does not handle zero length WRITE request correctly", the xdr decode routines for NFSv2 and NFSv3 reject requests that aren't the right length, so krb5i (for example) WRITE requests can get lost. This patch relaxes the appropriate test and enhances the related comment. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: J.

2008-01-13remove task_ppid_nr_nsRoland McGrath
task_ppid_nr_ns is called in three places. One of these should never have called it. In the other two, using it broke the existing semantics. This was presumably accidental. If the function had not been there, it would have been much more obvious to the eye that those patches were changing the behavior. We don't need this function. In task_state, the pid of the ptracer is not the ppid of the ptracer. In do_task_stat, ppid is the tgid of the real_parent, not its pid. I also moved the call outside of lock_task_sighand, since it doesn't need it. In sys_getppid, ppid is the tgid of the real_parent, not its pid.

2008-01-12pnpacpi: print resource shortage message only onceLen Brown
pnpacpi: exceeded the max number of IO resources: 40 While this message is a real error and should thus remain KERN_ERR (even a new dmesg line is seen as a regression by some, since it was not printed in 2.6.23...) it is certainly impolite to print this warning 50 times should you happen to have the oddball system with 90 io resources under a device... So print the warning just once. In 2.6.25 we'll get rid of the limits altogether and these warnings will vanish with them. http://bugzilla.kernel.org/show_bug.cgi?id=9535 Signed-off-by: Len Brown <len.brown@intel.com>

2008-01-12Use access mode instead of open flags to determine needed permissionsLinus Torvalds
Way back when (in commit 834f2a4a1554dc5b2598038b3fe8703defcbe467, aka "VFS: Allow the filesystem to return a full file pointer on open intent" to be exact), Trond changed the open logic to keep track of the original flags to a file open, in order to pass down the the intent of a dentry lookup to the low-level filesystem. However, when doing that reorganization, it changed the meaning of namei_flags, and thus inadvertently changed the test of access mode for directories (and RO filesystem) to use the wrong flag. So fix those test back to use access mode ("acc_mode") rather than the open flag ("flag"). Issue noticed by Bill Roman at Datalight.

2008-01-11ps3fb: fix deadlock on kexec()Jeremy Kerr
Since the introduction of the acquire_console_sem calls in 0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the kernel to deadlock: ps3fb_shutdown() -> unregister_framebuffer() -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND) -> fbcon_fb_unbind() -> unbind_con_driver() -> bind_con_driver() [ acquires console_sem ] -> fbcon_deinit() -> fbops->fb_release(newinfo, 0) -> ps3fb_release() -> ps3fb_sync() [ acquires console_sem ] This change avoids the deadlock by moving the acquire_console_sem() out of ps3fb_sync(), and puts it into the two other callsites, leaving ps3fb_release() to call ps3fb_sync() without the console semaphore. [Geert] - Corrected call sequence above - ps3fb_release() may be called with and without console_sem held. This is an inconsistency that should be fixed at the fb level, but for now, try to acquire console_sem in ps3fb_release(). I think it's safer to let ps3fb_release() try to acquire console_sem and not refresh the screen if it fails, than to call ps3fb_sync() without holding console_sem, as ps3fb_par may be modified at the same time, causing crashes or lockups. Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen when display flipping is disabled, which is an uncommon case (except during shutdown/kexec).

2008-01-11PM: ACPI and APM must not be enabled at the same timeLen Brown
ACPI and APM used "pm_active" to guarantee that they would not be simultaneously active. But pm_active was recently moved under CONFIG_PM_LEGACY, so that without CONFIG_PM_LEGACY, pm_active became a NOP -- allowing ACPI and APM to both be simultaneously enabled. This caused unpredictable results, including boot hangs. Further, the code under CONFIG_PM_LEGACY is scheduled for removal. So replace pm_active with pm_flags. pm_flags depends only on CONFIG_PM, which is present for both CONFIG_APM and CONFIG_ACPI. http://bugzilla.kernel.org/show_bug.cgi?id=9194 Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Rafael J.

2008-01-11[MIPS] Malta: Fix software reset on big endianDmitri Vorobiev
I noticed that the commit f197465384bf7ef1af184c2ed1a4e268911a91e3 (MIPS Tech: Get rid of volatile in core code) broke the software reset functionality for MIPS Malta boards in big-endian mode. According to the MIPS Malta board user's manual, writing the magic 32-bit GORESET value into the SOFTRES register initiates board soft reset. My experimentation has shown that the endianness of the GORESET integer should thereby be the same as the endianness, which has been set for the CPU itself. The writew() function used to write the magic value in the code introduced by the commit mentioned above, however, swaps bytes for big-endian kernels and transfers 16 bits instead of 32. The patch below replaces the writew() function by the __raw_writel() routine, which leaves the byte order intact and transfers the whole MIPS machine word. Trivial code cleanup (replacing spaces by a tab and cutting oversized lines to make checkpatch.pl happy) is also included. The patch was tested using a Malta evaluation board running in both BE and LE modes. For both modes, software reset was fully functional after the change. P.S. I suspect that the same commit broke the "standby" functionality for MIPS Atlas boards. However, I did not touch the Atlas code as I don't have such board at my disposal and also because the linux-mips.org Web site claims that Atlas support is scheduled for removal.
