git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace由 Linus Torvalds 提交于
Pull more tracing updates from Steven Rostedt: "This includes the final patch to clean up and fix the issue with the design of tracepoints and how a user could register a tracepoint and have that tracepoint not be activated but no error was shown. The design was for an out of tree module but broke in tree users. The clean up was to remove the saving of the hash table of tracepoint names such that they can be enabled before they exist (enabling a module tracepoint before that module is loaded). This added more complexity than needed. The clean up was to remove that code and just enable tracepoints that exist or fail if they do not. This removed a lot of code as well as the complexity that it brought. As a side effect, instead of registering a tracepoint by its name, the tracepoint needs to be registered with the tracepoint descriptor. This removes having to duplicate the tracepoint names that are enabled. The second patch was added that simplified the way modules were searched for. This cleanup required changes that were in the 3.15 queue as well as some changes that were added late in the 3.14-rc cycle. This final change waited till the two were merged in upstream and then the change was added and full tests were run. Unfortunately, the test found some errors, but after it was already submitted to the for-next branch and not to be rebased. Sparse errors were detected by Fengguang Wu's bot tests, and my internal tests discovered that the anonymous union initialization triggered a bug in older gcc compilers. Luckily, there was a bugzilla for the gcc bug which gave a work around to the problem. The third and fourth patch handled the sparse error and the gcc bug respectively.

ft_del_tpg checks tpg->tport is set before unlinking the tpg from the tport when the tpg is being removed. Set this pointer in ft_tport_create, or the unlinking won't happen in ft_del_tpg and tport->tpg will reference a deleted object. This patch sets tpg->tport in ft_tport_create, because that's what ft_del_tpg checks, and is the only way to get back to the tport to clear tport->tpg. The bug was occuring when: - lport created, tport (our per-lport, per-provider context) is allocated. tport->tpg = NULL - tpg created - a PRLI is received. ft_tport_create is called, tpg is found and tport->tpg is set - tpg removed. ft_tpg is freed in ft_del_tpg. Since tpg->tport was not set, tport->tpg is not cleared and points at freed memory - Future calls to ft_tport_create return tport via first conditional, instead of searching for new tpg by calling ft_lport_find_tpg. tport->tpg is still invalid, and will access freed memory. see https://bugzilla.redhat.com/show_bug.cgi?id=1071340 Cc: stable@vger.kernel.org # 3.0+ Signed-off-by: NAndy Grover <agrover@redhat.com> Signed-off-by: NNicholas Bellinger <nab@linux-iscsi.org>

This patch addresses an issue that occurs when an ABTS is received for an se_cmd that completes just before the sess_cmd_list is searched in core_tmr_abort_task(). When the sess_cmd_list is searched, since the ABTS and the FCP_CMND being aborted (that just completed) both have the same OXID, TFO->get_task_tag(TMR) returns a value that matches tmr->ref_task_tag (from TFO->get_task_tag(FCP_CMND)), and the Abort Task tries to abort itself. When this occurs, transport_wait_for_tasks() hangs forever since the TMR is waiting for itself to finish. This patch adds a check to core_tmr_abort_task() to make sure the TMR does not attempt to abort itself.

Pull x86 fixes from Peter Anvin: "This is a collection of minor fixes for x86, plus the IRET information leak fix (forbid the use of 16-bit segments in 64-bit mode)" NOTE! We may have to relax the "forbid the use of 16-bit segments in 64-bit mode" part, since there may be people who still run and depend on 16-bit Windows binaries under Wine. But I'm taking this in the current unconditional form for now to see who (if anybody) screams bloody murder. Maybe nobody cares. And maybe we'll have to update it with some kind of runtime enablement (like our vm.mmap_min_addr tunable that people who run dosemu/qemu/wine already need to tweak). * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels efi: Pass correct file handle to efi_file_{read,close} x86/efi: Correct EFI boot stub use of code32_start x86/efi: Fix boot failure with EFI stub x86/platform/hyperv: Handle VMBUS driver being a module x86/apic: Reinstate error IRQ Pentium erratum 3AP workaround x86, CMCI: Add proper detection of end of CMCI storms

Pull second set of ARM changes from Russell King: "This is the remainder of the ARM changes for this merge window.

The IRET instruction, when returning to a 16-bit segment, only restores the bottom 16 bits of the user space stack pointer. We have a software workaround for that ("espfix") for the 32-bit kernel, but it relies on a nonzero stack segment base which is not available in 32-bit mode. Since 16-bit support is somewhat crippled anyway on a 64-bit kernel (no V86 mode), and most (if not quite all) 64-bit processors support virtualization for the users who really need it, simply reject attempts at creating a 16-bit segment when running on top of a 64-bit kernel.

Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent Pull EFI fixes from Matt Fleming: "* Fix EFI boot regression introduced during the merge window where the firmware was reading random values from the stack because we were passing a pointer to the wrong object type. * Kernel corruption has been reported when booting with the EFI boot stub which was tracked down to setting a bogus value for bp->hdr.code32_start, resulting in corruption during relocation. * Olivier Martin reported that the wrong file handles were being passed to efi_file_(read|close), which works for x86 by luck due to the way that the FAT driver is implemented, but doesn't work on ARM."

New kexec-tools wants to pass kdump kernel needed memmap via E820 directly, instead of memmap=exactmap. This makes saved_max_pfn not be passed down to 2nd kernel. To keep 1st kernel and 2nd kernel using the same TCE table size, Muli suggest to hard code the size to max (8M). We can't get rid of saved_max_pfn this time, for backward compatibility with old first kernel and new second kernel. However new first kernel and old second kernel can not work unfortunately. v2->v1: - retain saved_max_pfn so new 2nd kernel can work with old 1st kernel from Vivek Signed-off-by: NWANG Chao <chaowang@redhat.com> Acked-by: NVivek Goyal <vgoyal@redhat.com> Acked-by: NMuli Ben-Yehuda <mulix@mulix.org> Acked-by: NJon Mason <jdmason@kudzu.us> Link: http://lkml.kernel.org/r/1394463120-26999-1-git-send-email-chaowang@redhat.comSigned-off-by: NH.
