2005-05-17[PATCH] md: fix splitting of md/linear request that cross a device boundaryNeilBrown
When a request crosses a boundary between devices, it needs to be split. But where we should calculate the amount of the request before the boundary to find the split-point, we care currently calculating the amount that is *after* the boundary !!!

2005-05-16[PATCH] Fix root hole in pktcdvdPeter Osterlund
ioctl_by_bdev may only be used INSIDE the kernel. If the "arg" argument refers to memory that is accessed by put_user/get_user in the ioctl function, the memory needs to be in the kernel address space (that's the set_fs(KERNEL_DS) doing in the ioctl_by_bdev). This works on i386 because even with set_fs(KERNEL_DS) the user space memory is still accessible with put_user/get_user. That is not true for s390. In short the ioctl implementation of the pktcdvd device driver is horribly broken.

2005-05-16[PATCH] Fix root hole in raw deviceStephen Tweedie
[Patch] Fix raw device ioctl pass-through Raw character devices are supposed to pass ioctls through to the block devices they are bound to. Unfortunately, they are using the wrong function for this: ioctl_by_bdev(), instead of blkdev_ioctl(). ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl, redirecting the user-space buffer access to the kernel address space. This is, needless to say, a bad thing. This was noticed first on s390, where raw IO was non-functioning. The s390 driver config does not actually allow raw IO to be enabled, which was the first part of the problem. Secondly, the s390 kernel address space is distinct from user, causing legal raw ioctls to fail. I've reproduced this on a kernel built with 4G:4G split on x86, which fails in the same way (-EFAULT if the address does not exist kernel-side; returns success without actually populating the user buffer if it does.) The patch below fixes both the config and address-space problems. It's based closely on a patch by Jan Glauber <jang@de.ibm.com>, which has been tested on s390 at IBM. I've tested it on x86 4G:4G (split address space) and x86_64 (common address space). Kernel-address-space access has been assigned CAN-2005-1264.

2005-05-06[PATCH] uml: Fix process exit raceBodo Stroesser
tt-mode closes switch_pipes in exit_thread_tt and kills processes in switch_to_tt, if the exit_state is EXIT_DEAD or EXIT_ZOMBIE. In very rare cases the exiting process can be scheduled out after having set exit_state and closed switch_pipes (from release_task it calls proc_pid_flush, which might sleep). If this process is to be restarted, UML failes in switch_to_tt with: write of switch_pipe failed, err = 9 We fix this by closing switch_pipes not in exit_thread_tt, but later in release_thread_tt. Additionally, we set switch_pipe[0] = 0 after closing. switch_to_tt must not kill "from" process depending on its exit_state, but must kill it after release_thread was processed only, so it examines switch_pipe[0] for its decision.

2005-05-06[PATCH] uml: S390 preparation, peekusr/pokeusr defined by subarchBodo Stroesser
s390 needs to change some parts of arch/um/kernel/ptrace.c. Thus, the code regarding PEEKUSER and POKEUSER are shifted to arch/um/sys-<subarch>/ptrace.c. Also s390 debug registers need to be updated, when singlestepping is switched on / off. Thus, setting/resetting of singlestepping is centralized in the new function set_singlestep(), which also inserts the macro SUBARCH_SET_SINGLESTEP(mode), if defined. Finally, s390 has the "ieee_instruction_pointer" in its registers, which also is allowed to be read via ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0); To implement this feature, sys_ptrace inserts the macro SUBARCH_PTRACE_SPECIAL, if defined.
