3205001 Jan Beulich 12 April 2012, 19:49:12 UTC drivers/rtc/rtc-efi.c: fix section mismatch warning efi_rtc_init() uses platform_driver_probe(), so there's no need to also set efi_rtc_driver's probe member (as it won't be used anyway). This fixes a modpost section mismatch warning (as efi_rtc_probe() validly is __init).

44e4360 Mathieu Desnoyers 12 April 2012, 19:49:12 UTC drivers/char/random.c: fix boot id uniqueness race /proc/sys/kernel/random/boot_id can be read concurrently by userspace processes. If two (or more) user-space processes concurrently read boot_id when sysctl_bootid is not yet assigned, a race can occur making boot_id differ between the reads. Because the whole point of the boot id is to be unique across a kernel execution, fix this by protecting this operation with a spinlock. Given that this operation is not frequently used, hitting the spinlock on each call should not be an issue.

92ae03f Linus Torvalds 06 April 2012, 21:32:32 UTC x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up This merges the 32- and 64-bit versions of the x86 strncpy_from_user() by just rewriting it in C rather than the ancient inline asm versions that used lodsb/stosb and had been duplicated for (trivial) differences between the 32-bit and 64-bit versions. While doing that, it also speeds them up by doing the accesses a word at a time. Finally, the new routines also properly handle the case of hitting the end of the address space, which we have never done correctly before (fs/namei.c has a hack around it for that reason). Despite all these improvements, it actually removes more lines than it adds, due to the de-duplication. Also, we no longer export (or define) the legacy __strncpy_from_user() function (that was defined to not do the user permission checks), since it's not actually used anywhere, and the user address space checks are built in to the new code. Other architecture maintainers have been notified that the old hack in fs/namei.c will be going away in the 3.5 merge window, in case they copied the x86 approach of being a bit cavalier about the end of the address space.

79549c6 Oleg Nesterov 09 April 2012, 19:03:50 UTC cred: copy_process() should clear child->replacement_session_keyring keyctl_session_to_parent(task) sets ->replacement_session_keyring, it should be processed and cleared by key_replace_session_keyring(). However, this task can fork before it notices TIF_NOTIFY_RESUME and the new child gets the bogus ->replacement_session_keyring copied by dup_task_struct(). This is obviously wrong and, if nothing else, this leads to put_cred(already_freed_cred). change copy_creds() to clear this member. If copy_process() fails before this point the wrong ->replacement_session_keyring doesn't matter, exit_creds() won't be called.

ca9248d Bob Peterson 10 April 2012, 12:56:04 UTC GFS2: Allow caching of rindex glock This patch allows caching of the rindex glock. We were previously setting the GL_NOCACHE bit when the glock was released. That forced the rindex inode to be invalidated, which caused us to re-read rindex at the next access. However, it caused the glock to be unnecessarily bounced around the cluster. This patch allows the glock to remain cached, but it still causes the rindex to be re-read once it has been written to by gfs2_grow. Ben and I have tested single-node gfs2_grow cases and I've tested clustered gfs2_grow cases on my four-node cluster.

08f1ec8 Benjamin Herrenschmidt 10 April 2012, 07:21:35 UTC powerpc: Fix page fault with lockdep regression commit a546498f3bf9aac311c66f965186373aee2ca0b0 introduced a regression on 32-bit when irq tracing is enabled by exposing an old bug in our irq tracing code for exception entry. The code would save and restore some GPRs around the calls to the C lockdep code, however, it tries to be too smart for its own good and restores some of the GPRs from the exception frame (as saved there on exception entry). However, for page faults, we do replace those GPRs with arguments to do_page_fault before we call transfer_to_handler and so restoring from the exception frame is plain wrong in this case. This was fine as long as we didn't touch the interrupt state when taking page fault, but when I started doing it, it would trigger the lockdep calls and the bug. This fixes it by cleaning up that code a bit. It did create a small stack frame for the sake of backtraces, so let's make it a bit bigger and use it to save and restore the stuff we care about.

This sorting and merging into the canonical sections are done by the linker. Unfortunately modpost to generate Module.symvers file parses vmlinux.o (which is not linked yet) and all modules object files (which aren't linked yet). These aren't sanitized by the linker yet.

83dbbdb David Rientjes 09 April 2012, 23:56:18 UTC android, lowmemorykiller: remove task handoff notifier The task handoff notifier leaks task_struct since it never gets freed after the callback returns NOTIFY_OK, which means it is responsible for doing so. It turns out the lowmemorykiller actually doesn't need this notifier at all. It's used to prevent unnecessary killing by waiting for a thread to exit as a result of lowmem_shrink(), however, it's possible to do this in the same way the kernel oom killer works by setting TIF_MEMDIE and avoid killing if we're still waiting for it to exit. The kernel oom killer will already automatically set TIF_MEMDIE for threads that are attempting to allocate memory that have a fatal signal. The thread selected by lowmem_shrink() will have such a signal after the lowmemorykiller sends it a SIGKILL, so this won't result in an unnecessary use of memory reserves for the thread to exit. This has the added benefit that we don't have to rely on CONFIG_PROFILING to prevent needlessly killing tasks.

No, this is the correct patch: RADIO_MAXIRADIO should be treated just like RADIO_SF16FMR2, I just didn't realize at the time that it had to be added as a SND_TEA575X dependency.

556a044 Chris Rankin 06 April 2012, 21:38:18 UTC [media] dvb_frontend: regression fix: userspace ABI broken for xine The commit e399ce77e6e has broken the DVB ABI for xine: The problem is that xine is expecting every event after a successful FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless of whether the tuning process has LOCKed yet. What used to happen is that the events inherited the initial tuning parameters from the FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now not initialised until the status contains the FE_HAS_LOCK bit. You might argue that this behaviour is intentional, except that if an application other than xine uses the DVB adapter and manages to set the parameters_out.frequency field to something other than zero, then xine no longer has any problems until either the adapter is replugged or the kernel modules reloaded. This can only mean that the fepriv->parameters_out struct still contains the (stale) tuning information from the previous application.

f68e556 Linus Torvalds 06 April 2012, 20:54:56 UTC Make the "word-at-a-time" helper functions more commonly usable I have a new optimized x86 "strncpy_from_user()" that will use these same helper functions for all the same reasons the name lookup code uses them. This is preparation for that. This moves them into an architecture-specific header file. It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this. (and if it turns out that non-x86 architectures don't start using this, then having it in an architecture-specific header is still the right thing to do, of course) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 06 April 2012, 20:54:56 UTC

Let the natural sequence generated by the splice paths, and the assosciated MSG_MORE settings, guide the tcp_push() calls. Otherwise what goes out of TCP is spaghetti and doesn't batch effectively into GSO/TSO clusters. From Eric Dumazet. 12) Once we put a SKB into either the netlink receiver's queue or a socket error queue, it can be consumed and freed up, therefore we cannot touch it after queueing it like that. Fixes from Eric Dumazet. 13) PPP has this annoying behavior in that for every transmit call it immediately stops the TX queue, then calls down into the next layer to transmit the PPP frame. But if that next layer can take it immediately, it just un-stops the TX queue right before returning from the transmit method. Besides being useless work, it makes several facilities unusable, in particular things like the equalizers. Well behaved devices should only stop the TX queue when they really are full, and in PPP's case when it gets backlogged to the downstream device. David Woodhouse therefore fixed PPP to not stop the TX queue until it's downstream can't take data any more. 14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver changes, re-add.

That function calls mp_find_ioapics to get the 'struct ioapic' structure - which along with the mp_irq[x] is used to figure out the default values and the polarity/trigger overrides. Since the mp_find_ioapics now returns -1 [b/c the IOAPIC is filled with 0xffffffff], the acpi_get_override_irq() stops trying to lookup in the mp_irq[x] the proper INT_SRV_OVR and we can't install the SCI interrupt. The proper fix for this is going in v3.5 and adds an x86_io_apic_ops struct so that platforms can override it. But for v3.4 lets carry this work-around. This patch does that by providing a slightly different variant of the fake IOAPIC entries. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> 06 April 2012, 16:13:06 UTC

Try to work around this by using a three second write timeout instead. This is a generalized version of a patch from Chase Maupin <Chase.Maupin@ti.com>, whose patch description said: * With certain SD cards timeouts like the following have been seen due to an improper calculation of the dto value: mmcblk0: error -110 transferring data, sector 4126233, nr 8, card status 0xc00 * By removing the dto calculation and setting the timeout value to the maximum specified by the SD card specification part A2 section 2.2.15 these timeouts can be avoided. * This change has been used by beagleboard users as well as the Texas Instruments SDK without a negative impact. * There are multiple discussion threads about this but the most relevant ones are: * http://talk.maemo.org/showthread.php?p=1000707#post1000707 * http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42213.html * Original proposal for this fix was done by Sukumar Ghoral of Texas Instruments * Tested using a Texas Instruments AM335x EVM Signed-off-by: Paul Walmsley <paul@pwsan.com> Tested-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Chris Ball <cjb@laptop.org> 06 April 2012, 00:32:34 UTC

The driver should not try to switch to 1.8V when the SD 3.0 host controller does not have any UHS capabilities bits set (SDR50, DDR50 or SDR104). See page 72 of "SD Specifications Part A2 SD Host Controller Simplified Specification Version 3.00" under "1.8V Signaling Enable". Instead of setting SDR12 and SDR25 in the host capabilities data structure for all V3.0 host controllers, only set them if SDR104, SDR50 or DDR50 is set in the host capabilities register. This will prevent the switch to 1.8V later.

According to eMMC specification, valid voltage for high voltage cards is 2.7v to 3.6v. This patch ensures that 2.7v to 3.6v VDD range is treated as valid range. Also, failure to set the power class shouldn't be treated as fatal error because even if setting the power class fails, card can still work in default power class. If mmc_select_powerclass() returns error, just print the warning message and go ahead with rest of the card initialization.

e841a7c Rafael J. Wysocki 01 April 2012, 04:34:58 UTC mmc: sdio: Use empty system suspend/resume callbacks at the bus level Neil Brown reports that commit 35cd133c PM: Run the driver callback directly if the subsystem one is not there breaks suspend for his libertas wifi, because SDIO has a protocol where the suspend method can return -ENOSYS and this means "There is no point in suspending, just turn me off". Moreover, the suspend methods provided by SDIO drivers are not supposed to be called by the PM core or bus-level suspend routines (which aren't presend for SDIO). Instead, when the SDIO core gets to suspend the device's ancestor, it calls the device driver's suspend function, catches the ENOSYS, and turns the device off. The commit above breaks the SDIO core's assumption that the device drivers' callbacks won't be executed if it doesn't provide any bus-level callbacks. If fact, however, this assumption has never been really satisfied, because device class or device type suspend might very well use the driver's callback even without that commit. The simplest way to address this problem is to make the SDIO core tell the PM core to ignore driver callbacks, for example by providing no-operation suspend/resume callbacks at the bus level for it, which is implemented by this change.
