5d12045 Linus Torvalds 19 May 2012, 22:28:22 UTC Merge branch 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case. This backports the workaround from the x86/trampoline branch, and as Peter says: "This is not a minimal fix, not at all, but it is a tested code base." * 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: When printing an error, say relative or absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug x86, realmode: 16-bit real-mode code support for relocs tool (*) That's a manly release numbering system.

62ade86 Hugh Dickins 18 May 2012, 18:28:34 UTC memcg,thp: fix res_counter:96 regression Occasionally, testing memcg's move_charge_at_immigrate on rc7 shows a flurry of hundreds of warnings at kernel/res_counter.c:96, where res_counter_uncharge_locked() does WARN_ON(counter->usage < val). The first trace of each flurry implicates __mem_cgroup_cancel_charge() of mc.precharge, and an audit of mc.precharge handling points to mem_cgroup_move_charge_pte_range()'s THP handling in commit 12724850e806 ("memcg: avoid THP split in task migration"). Checking !mc.precharge is good everywhere else, when a single page is to be charged; but here the "mc.precharge -= HPAGE_PMD_NR" likely to follow, is liable to result in underflow (a lot can change since the precharge was estimated). Simply check against HPAGE_PMD_NR: there's probably a better alternative, trying precharge for more, splitting if unsuccessful; but this one-liner is safer for now - no kernel/res_counter.c:96 warnings seen in 26 hours.

6520fe5 H. Peter Anvin 08 May 2012, 18:22:24 UTC x86, realmode: 16-bit real-mode code support for relocs tool A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree. [ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ] Signed-off-by: H.

f402693 Mike Snitzer 19 May 2012, 00:01:01 UTC dm thin: fix table output when pool target disables discard passdown internally When the thin pool target clears the discard_passdown parameter internally, it incorrectly changes the table line reported to userspace. This breaks dumb string comparisons on these table lines in generic userspace device-mapper library code and leads to tables being reloaded repeatedly when nothing is actually meant to be changing. This patch corrects this by no longer changing the table line when discard passdown was disabled. We can still tell when discard passdown is overridden by looking for the message "Discard unsupported by data device (sdX): Disabling discard passdown." This automatic detection is also moved from the 'load' to the 'resume' so that it is re-evaluated should the properties of underlying devices change.

30a08bf Linus Torvalds 18 May 2012, 18:32:15 UTC proc: move fd symlink i_mode calculations into tid_fd_revalidate() Instead of doing the i_mode calculations at proc_fd_instantiate() time, move them into tid_fd_revalidate(), which is where the other inode state (notably uid/gid information) is updated too. Otherwise we'll end up with stale i_mode information if an fd is re-used while the dentry still hangs around. Not that anything really *cares* (symlink permissions don't really matter), but Tetsuo Handa noticed that the owner read/write bits don't always match the state of the readability of the file descriptor, and we _used_ to get this right a long time ago in a galaxy far, far away. Besides, aside from fixing an ugly detail (that has apparently been this way since commit 61a28784028e: "proc: Remove the hard coded inode numbers" in 2006), this removes more lines of code than it adds. And it just makes sense to update i_mode in the same place we update i_uid/gid. Al Viro correctly points out that we could just do the inode fill in the inode iops ->getattr() function instead. However, that does require somewhat slightly more invasive changes, and adds yet *another* lookup of the file descriptor. We need to do the revalidate() for other reasons anyway, and have the file descriptor handy, so we might as well fill in the information at this point.

e6d9668 Chris Metcalf 18 May 2012, 17:33:24 UTC tilegx: enable SYSCALL_WRAPPERS support Some discussion with the glibc mailing lists revealed that this was necessary for 64-bit platforms with MIPS-like sign-extension rules for 32-bit values. The original symptom was that passing (uid_t)-1 to setreuid() was failing in programs linked -pthread because of the "setxid" mechanism for passing setxid-type function arguments to the syscall code. SYSCALL_WRAPPERS handles ensuring that all syscall arguments end up with proper sign-extension and is thus the appropriate fix for this problem. On other platforms (s390, powerpc, sparc64, and mips) this was fixed in 2.6.28.6. The general issue is tracked as CVE-2009-0029.

5c7dd71 Rafael J. Wysocki 17 May 2012, 22:39:35 UTC ACPI / PCI / PM: Fix device PM regression related to D3hot/D3cold Commit 1cc0c998fdf2 ("ACPI: Fix D3hot v D3cold confusion") introduced a bug in __acpi_bus_set_power() and changed the behavior of acpi_pci_set_power_state() in such a way that it generally doesn't work as expected if PCI_D3hot is passed to it as the second argument. First off, if ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) is passed to __acpi_bus_set_power() and the explicit_set flag is set for the D3cold state, the function will try to execute AML method called "_PS4", which doesn't exist. Fix this by adding a check to ensure that the name of the AML method to execute for transitions to ACPI_STATE_D3_COLD is correct in __acpi_bus_set_power(). Also make sure that the explicit_set flag for ACPI_STATE_D3_COLD will be set if _PS3 is present and modify acpi_power_transition() to avoid accessing power resources for ACPI_STATE_D3_COLD, because they don't exist. Second, if PCI_D3hot is passed to acpi_pci_set_power_state() as the target state, the function will request a transition to ACPI_STATE_D3_HOT instead of ACPI_STATE_D3. However, ACPI_STATE_D3_HOT is now only marked as supported if the _PR3 AML method is defined for the given device, which is rare. This causes problems to happen on systems where devices were successfully put into ACPI D3 by pci_set_power_state(PCI_D3hot) which doesn't work now. In particular, some unused graphics adapters are not turned off as a result. To fix this issue restore the old behavior of acpi_pci_set_power_state(), which is to request a transition to ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) if either PCI_D3hot or PCI_D3cold is passed to it as the argument. This approach is not ideal, because generally power should not be removed from devices if PCI_D3hot is the target power state, but since this behavior is relied on, we have no choice but to restore it at the moment and spend more time on designing a better solution in the future.

bad115c Willy Tarreau 17 May 2012, 11:14:14 UTC tcp: do_tcp_sendpages() must try to push data out on oom conditions Since recent changes on TCP splicing (starting with commits 2f533844 "tcp: allow splice() to build full TSO packets" and 35f9c09f "tcp: tcp_sendpages() should call tcp_push() once"), I started seeing massive stalls when forwarding traffic between two sockets using splice() when pipe buffers were larger than socket buffers. Latest changes (net: netdev_alloc_skb() use build_skb()) made the problem even more apparent. The reason seems to be that if do_tcp_sendpages() fails on out of memory condition without being able to send at least one byte, tcp_push() is not called and the buffers cannot be flushed. After applying the attached patch, I cannot reproduce the stalls at all and the data rate it perfectly stable and steady under any condition which previously caused the problem to be permanent. The issue seems to have been there since before the kernel migrated to git, which makes me think that the stalls I occasionally experienced with tux during stress-tests years ago were probably related to the same issue. This issue was first encountered on 3.0.31 and 3.2.17, so please backport to -stable.

56cb248 Will Deacon 15 May 2012, 14:51:54 UTC ARM: 7419/1: vfp: fix VFP flushing regression on sigreturn path Commit ff9a184c ("ARM: 7400/1: vfp: clear fpscr length and stride bits on entry to sig handler") flushes the VFP state prior to entering a signal handler so that a VFP operation inside the handler will trap and force a restore of ABI-compliant registers. Reflushing and disabling VFP on the sigreturn path is predicated on the saved thread state indicating that VFP was used by the handler -- however for SMP platforms this is only set on context-switch, making the check unreliable and causing VFP register corruption in userspace since the register values are not necessarily those restored from the sigframe. This patch unconditionally flushes the VFP state after a signal handler. Since we already perform the flush before the handler and the flushing itself happens lazily, the redundant flush when VFP is not used by the handler is essentially a nop.

ec13ee8 Michael S. Tsirkin 16 May 2012, 07:57:12 UTC virtio_net: invoke softirqs after __napi_schedule __napi_schedule might raise softirq but nothing causes do_softirq to trigger, so it does not in fact run. As a result, the error message "NOHZ: local_softirq_pending 08" sometimes occurs during boot of a KVM guest when the network service is started and we are oom: ... Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0...NOHZ: local_softirq_pending 08 done. [ OK ] ... Further, receive queue processing might get delayed indefinitely until some interrupt triggers: virtio_net expected napi to be run immediately. One way to cause do_softirq to be executed is by invoking local_bh_enable(). As __napi_schedule is normally called from bh or irq context, this seems to make sense: disable bh before __napi_schedule and enable afterwards. In fact it's a very complicated way of calling do_softirq(), and works since this function is only used when we are not in interrupt context. It's not hot at all, in any ideal scenario.

We don't want a timer going off after an mddev_suspend is called. This is especially true with device-mapper, since it can call the destructor function immediately following a suspend.

fc327e2 Chris Metcalf 28 April 2012, 22:51:43 UTC arch/tile: fix up some issues in calling do_work_pending() First, we were at risk of handling thread-info flags, in particular do_signal(), when returning from kernel space. This could happen after a failed kernel_execve(), or when forking a kernel thread. The fix is to test in do_work_pending() for user_mode() and return immediately if so; we already had this test for one of the flags, so I just hoisted it to the top of the function. Second, if a ptraced process updated the callee-saved registers in the ptregs struct and then processed another thread-info flag, we would overwrite the modifications with the original callee-saved registers. To fix this, we add a register to note if we've already saved the registers once, and skip doing it on additional passes through the loop. To avoid a performance hit from the couple of extra instructions involved, I modified the GET_THREAD_INFO() macro to be guaranteed to be one instruction, then bundled it with adjacent instructions, yielding an overall net savings.

The reason it wasn't caught earlier is that it only occurs with specific Bluetooth adapters. As for the security level patch, this fixes L2CAP socket based security level elevation during a connection.

The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.

As it requires linux/sched.h even when CONFIG_BLOCK=n, move this out of the #ifdef.

b99215c David S. Miller 13 May 2012, 19:45:13 UTC bonding: Fix LACPDU rx_dropped commit. I applied the wrong version of Jiri's bonding fix in commit 13a8e0c8cdb43982372bd6c65fb26839c8fd8ce9 ("bonding: don't increase rx_dropped after processing LACPDUs") I applied v3, which introduces warnings I asked him to fix, instead of v4 which properly takes care of those issues. This inter-diffs such that the warnings are now gone. Signed-off-by: David S. Miller <davem@davemloft.net> 13 May 2012, 19:45:13 UTC

fd717cd Marek Szyprowski 11 May 2012, 21:17:59 UTC ARM: EXYNOS: use s5p-timer for UniversalC210 board Commit 069d4e743 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds.
