[RFC 0/4] dma-buf Constraints-Enabled Allocation helpers

by Sumit Semwal

Hi, Why: ==== While sharing buffers using dma-buf, currently there's no mechanism to let devices share their memory access constraints with each other to allow for delayed allocation of backing storage. This RFC attempts to introduce the idea of memory constraints of a device, and how these constraints can be shared and used to help allocate buffers that can satisfy requirements of all devices attached to a particular dma-buf. How: ==== A constraints_mask is added to dma_parms of the device, and at the time of each device attachment to a dma-buf, the dma-buf uses this constraints_mask to calculate the access_mask for the dma-buf. Allocators can be defined for each of these constraints_masks, and then helper functions can be used to allocate the backing storage from the matching allocator satisfying the constraints of all devices interested. A new miscdevice, /dev/cenalloc [1] is created, which acts as the dma-buf exporter to make this transparent to the devices. More details in the patch description of "cenalloc: Constraint-Enabled Allocation helpers for dma-buf". At present, the constraint_mask is only a bitmask, but it should be possible to change it to a struct and adapt the constraint_mask calculation accordingly, based on discussion. Important requirement: ====================== Of course, delayed allocation can only work if all participating devices will wait for other devices to have 'attached' before mapping the buffer for the first time. As of now, users of dma-buf(drm prime, v4l2 etc) call the attach() and then map_attachment() almost immediately after it. This would need to be changed if they were to benefit from constraints. What 'cenalloc' is not: ======================= - not 'general' allocator helpers - useful only for constraints-enabled devices that share buffers with others using dma-buf. - not a replacement for existing allocation mechanisms inside various subsystems; merely a possible alternative. - no page-migration - it would be very complementary to the delayed allocation suggested here. TODOs: ====== - demonstration test cases - vma helpers for allocators - more sample allocators - userspace ioctl (It should be a simple one, and we have one ready, but wanted to agree on the kernel side of things first) May the brickbats begin, please! :) Best regards, ~Sumit. [1]: 'C'onstraints 'EN'abled 'ALLOC'ation helpers = cenalloc: it might not be a very appealing name, so suggestions are very welcome!

[RFC v2 00/10] kdb: Kiosk (reduced capabilities) mode

by Daniel Thompson

This patchset implements "kiosk" mode for KDB debugger and is a continuation of previous work by Anton Vorontsov (dating back to late 2012). When kiosk mode is engaged several kdb commands become disabled leaving only status reporting functions working normally. In particular arbitrary memory read/write is prevented and it is no longer possible to alter program flow. Note that the commands that remain enabled are sufficient to run the post-mortem macro commands, dumpcommon, dumpall and dumpcpu. One of the motivating use-cases for this work is to realize post-mortem on embedded devices (such as phones) without allowing the debug facility to be easily exploited to compromise user privacy. In principle this means the feature can be enabled on production devices. There are a few patches, some are just cleanups, some are churn-ish cleanups, but inevitable. And the rest implements the mode -- after all the preparations, everything is pretty straightforward. The first patch is actually a pure bug fix (arguably unrelated to kiosk mode) but collides with the kiosk code to honour the sysrq mask so I have included it here. Changes since v1 (circa 2012): * ef (Display exception frame) is essentially an overly complex peek and has therefore been marked unsafe * bt (Stack traceback) has been marked safe only with no arguments * sr (Magic SysRq key) honours the sysrq mask when called in kiosk mode * Fixed over-zealous blocking of macro commands * Symbol lookup is forbidden by kdbgetaddrarg (more robust, better error reporting to user) * Fix deadlock in sr (Magic SysRq key) * Better help text in kiosk mode * Default (kiosk on/off) can be changed From the config file. Anton Vorontsov (7): kdb: Remove currently unused kdbtab_t->cmd_flags kdb: Rename kdb_repeat_t to kdb_cmdflags_t, cmd_repeat to cmd_flags kdb: Rename kdb_register_repeat() to kdb_register_flags() kdb: Use KDB_REPEAT_* values as flags kdb: Remove KDB_REPEAT_NONE flag kdb: Mark safe commands as KDB_SAFE and KDB_SAFE_NO_ARGS kdb: Add kiosk mode Daniel Thompson (3): sysrq: Implement __handle_sysrq_nolock to avoid recursive locking in kdb kdb: Improve usability of help text when running in kiosk mode kdb: Allow access to sensitive commands to be restricted by default drivers/tty/sysrq.c | 11 ++- include/linux/kdb.h | 20 ++-- include/linux/sysrq.h | 1 + kernel/debug/kdb/kdb_bp.c | 22 ++--- kernel/debug/kdb/kdb_main.c | 207 +++++++++++++++++++++++------------------ kernel/debug/kdb/kdb_private.h | 3 +- kernel/trace/trace_kdb.c | 4 +- lib/Kconfig.kgdb | 21 +++++ 8 files changed, 172 insertions(+), 117 deletions(-) -- 1.9.0

[RFC PATCH] kgdb: Timeout if secondary CPUs ignore the roundup

by Daniel Thompson

Currently if an active CPU fails to respond to a roundup request the CPU that requested the roundup will become stuck. This needlessly reduces the robustness of the debugger. This patch introduces a timeout allowing the system state to be examined even when the system contains unresponsive processors. It also modifies kdb's cpu command to make it censor attempts to switch to unresponsive processors and to report their state as (D)ead.
