2007-03-12[PATCH] Fix VMI and COMPAT_VDSO for 2.6.21Zachary Amsden
VMI is broken under COMPAT_VDSO, as Xen and other non hardware assisted hypervisors will be. I have been working on a fix for this which works for older glibcs that panic when the new relocatable VDSO is used. However, I believe at this time that the fix is going to be too radical to consider at this stage in the release of 2.6.21. We don't expect this config option to be turned on by vendors for new distributions, so at this point we are willing to drop support for it when VMI is compiled in, and work on a patch for 2.6.22 which more fully addresses the problem.

Fix atomicity of TIF update in flush_thread() for sparc64 Fixes correctly the race by using *_ti_thread_flag. Race : parent process executing : sys_ptrace() (lock_kernel()) (ptrace_get_task_struct(pid)) arch_ptrace() ptrace_detach() ptrace_disable(child); clear_singlestep(child); clear_tsk_thread_flag(child, TIF_SINGLESTEP); (which clears the TIF_SINGLESTEP flag atomically from a different process) (put_task_struct(child)) (unlock_kernel()) And at the same time, in the child process : sys_execve() do_execve() search_binary_handler() load_elf_binary() flush_old_exec() flush_thread() doing a non-atomic thread flag update Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: David S.

2007-03-10[POWERPC] Fix spu SLB invalidationsBenjamin Herrenschmidt
The SPU code doesn't properly invalidate SPUs SLBs when necessary, for example when changing a segment size from the hugetlbfs code. In addition, it saves and restores the SLB content on context switches which makes it harder to properly handle those invalidations. This patch removes the saving & restoring for now, something more efficient might be found later on. It also adds a spu_flush_all_slbs(mm) that can be used by the core mm code to flush the SLBs of all SPEs that are running a given mm at the time of the flush. In order to do that, it adds a spinlock to the list of all SPEs and move some bits & pieces from spufs to spu_base.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2007-03-08[IA64] Proper handling of TLB errors from duplicate itr.d dropinsRuss Anderson
Jack Steiner noticed that duplicate TLB DTC entries do not cause a linux panic. See discussion: http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html The current TLB recovery code is recovering from the duplicate itr.d dropins, masking the underlying problem. This change modifies the MCA recovery code to look for the TLB check signature of the duplicate TLB entry and panic in that case.

2007-03-08[PATCH] uml: arch_prctl should set thread fsJeff Dike
In my previous x86_64 thread fix, I forgot to initialize thread.arch.fs in arch_prctl. A process calling arch_prctl to set %fs would lose it on the next context switch. It also turns out that you can switch to a process which is in the process of exiting and which has lost its mm. In this case, it's worse than useless to try to call arch_prctl on the host process.

2007-03-08[PATCH] Add epoll compat_ code to fs/compat.cDavide Libenzi
IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait.

2007-03-08[PATCH] x86_64: fix 2.6.18 regression - PTRACE_OLDSETOPTIONS should be acceptedPaolo 'Blaisorblade' Giarrusso
Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c and forced by binary compatibility. UML/32bit breaks because of this - since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible with 2.4 host kernels. Until 2.6.17 (commit f0f2d6536e3515b5b1b7ae97dc8f176860c8c2ce) we had: default: return sys_ptrace(request, pid, addr, data); Instead here we have: case PTRACE_GET_THREAD_AREA: case ...: return sys_ptrace(request, pid, addr, data); default: return -EINVAL; This change was a style change - when a case is added, it must be explicitly tested this way. In this case, not enough testing was done.

2007-03-08[PATCH] um: mark both consoles as CON_ANYTIMEPaolo 'Blaisorblade' Giarrusso
Since both UML consoles do not use percpu variables, they may be called when the cpu is still offline, and they may be marked CON_ANYTIME (this is documented in kernel/printk.c, grep for CON_ANYTIME to find mentions of this). Works well in testing done with lock debug enabled, should be safe but is not needed for next release. This would probably help also stderr_console.c, but this is yet to test.
