2020-12-03cifs: refactor create_sd_buf() and and avoid corrupting the bufferRonnie Sahlberg
When mounting with "idsfromsid" mount option, Azure corrupted the owner SIDs due to excessive padding caused by placing the owner fields at the end of the security descriptor on create. Placing owners at the front of the security descriptor (rather than the end) is also safer, as the number of ACEs (that follow it) are variable.

2020-12-03scripts: kernel-doc: fix parsing function-like typedefsMauro Carvalho Chehab
Changeset 6b80975c6308 ("scripts: kernel-doc: fix typedef parsing") added support for things like: typedef unsigned long foo(); However, it caused a regression on this prototype: typedef bool v4l2_check_dv_timings_fnc(const struct v4l2_dv_timings *t, void *handle); This is only noticed after adding a patch that checks if the kernel-doc identifier matches the typedef: ./scripts/kernel-doc -none $(git grep '^.. kernel-doc::' Documentation/ |cut -d ' ' -f 3|sort|uniq) 2>&1|grep expecting include/media/v4l2-dv-timings.h:38: warning: expecting prototype for typedef v4l2_check_dv_timings_fnc. Prototype was for typedef nc instead The problem is that, with the new parsing logic, it is not checking for complete words at the type part. Fix it by adding a \b at the end of each type word at the regex. fixes: 6b80975c6308 ("scripts: kernel-doc: fix typedef parsing") Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/218ff56dcb8e73755005d3fb64586eb1841a276b.1606896997.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2020-12-03scripts: get_feat.pl: use its implementation for list-arch.shMauro Carvalho Chehab
Add support for the same output format as the bash script, and use its implementation instead of the previous one. I opted to do such patch in order to have a single script responsible for parsing Documentation/features and produce different outputs. As someone may rely on the past format, which is easy to parse it, get_feat.pl now gains a new command with the same output format as the previous script. As a side effect, the perl script is a lot faster, as it reads each file only once, instead of parsing files several times via a for command and grep commands inside it. This patch also changes the features list order to be case-insensitive, in order to better match the output of the existing script.

2020-12-03scripts: get_feat.pl: add a script to handle Documentation/featuresMauro Carvalho Chehab
The Documentation/features contains a set of parseable files. It is not worth converting them to ReST format, as they're useful the way it is. It is, however, interesting to parse them and produce output on different formats: 1) Output the contents of a feature in ReST format; 2) Output what features a given architecture supports; 3) Output a matrix with features x architectures.

2020-12-03dt-bindings: timer: Add new OST support for the upcoming new driver.周琰杰 (Zhou Yanjie)
The new OST has one global timer and two or four percpu timers, so there will be three combinations in the upcoming new OST driver: the original GLOBAL_TIMER + PERCPU_TIMER, the new GLOBAL_TIMER + PERCPU_TIMER0/1 and GLOBAL_TIMER + PERCPU_TIMER0/1/2/3, For this, add the macro definition about OST_CLK_PERCPU_TIMER0/1/2/3. And in order to ensure that all the combinations work normally, the original ABI values of OST_CLK_PERCPU_TIMER and OST_CLK_GLOBAL_TIMER need to be exchanged to ensure that in any combinations, the clock can be registered (by calling clk_hw_register()) from index 0. Before this patch, OST_CLK_PERCPU_TIMER and OST_CLK_GLOBAL_TIMER are only used in two places, one is when using "assigned-clocks" to configure the clocks in the DTS file; the other is when registering the clocks in the sysost driver. When the values of these two ABIs are exchanged, the ABI value used by sysost driver when registering the clock, and the ABI value used by DTS when configuring the clock using "assigned-clocks" will also change accordingly. Therefore, there is no situation that causes the wrong clock to the configured. Therefore, exchanging ABI values will not cause errors in the existing codes when registering and configuring the clocks. Currently, in the mainline, only X1000 and X1830 are using sysost driver, and the upcoming X2000 will also use sysost driver. This patch has been tested on all three SoCs and all works fine.

2020-12-03drm/msm: Fix use-after-free in msm_gem with carveoutIskren Chernev
When using gem with vram carveout the page allocation is managed via drm_mm. The necessary drm_mm_node is allocated in add_vma, but it is referenced in msm_gem_object as well. It is freed before the drm_mm_node has been deallocated leading to use-after-free on every single vram allocation. Currently put_iova is called before put_pages in both msm_gem_free_object and msm_gem_purge: put_iova -> del_vma -> kfree(vma) // vma holds drm_mm_node /* later */ put_pages -> put_pages_vram -> drm_mm_remove_node( msm_obj->vram_node) // vram_node is a ref to // drm_mm_node; in _msm_gem_new It looks like del_vma does nothing else other than freeing the vma object and removing it from it's list, so delaying the deletion should be harmless. This patch splits put_iova in put_iova_spaces and put_iova_vmas, so the vma can be freed after the mm_node has been deallocated with the mm. Note: The breaking commit separated the vma allocation from within msm_gem_object to outside, so the vram_node reference became outside the msm_gem_object allocation, and freeing order was therefore overlooked.
