2014-12-23Docs: SubmittingPatches: miscellaneous cleanupsJonathan Corbet1-23/+38
Changes to make the formatting a bit more consistent and fix up wording in various places. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2014-12-23Docs: SubmittingPatches: update follow-through instructionsJonathan Corbet1-28/+22
SubmittingPatches was written in the "keep sending to Linus until something shows up in a release" era. Given that we don't do things that way anymore and the system is far less lossy, update this information and add some hints on responding to reviewer comments.

SubmittingPatches had two sections on selecting recipients; both were showing their age. Unify them into a single section that more closely reflects how we do things now. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2014-12-23Docs: Bring SubmittingPatches more into the git eraJonathan Corbet1-29/+87
Much of the information in SubmittingPatches shows its pre-git history. Clean that up a bit and rephrase things with the assumption that developers will be using git. Also rewrite the "pull requests" section and include information on using signed tags. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2014-12-23Merge tag 'drm/tegra/for-3.19-rc1-fixes' of ↵Dave Airlie5-30/+150
git://people.freedesktop.org/~tagr/linux into drm-fixes drm/tegra: Fixes for v3.19-rc1 This is a set of fixes for two regressions and one bug in the IOMMU mapping code. It turns out that all of these issues turn up primarily on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers that aren't multiples of the page size. I happened to be testing HDMI with 1080p while writing the code and framebuffers for that happen to fit exactly within 2025 pages of 4 KiB each. One of the regressions is caused by the IOMMU code allocating pages from shmem which can have associated cache lines. If the pages aren't flushed then these cache lines may be flushed later on and cause framebuffer corruption. I'm not sure why I didn't see this before. Perhaps the board that I was using had enough RAM so that the pages shmem would hand out had a better chance of being unused. Or maybe I didn't look too closely. The fix for this is to fake up an SG table so that it can be passed to the DMA API. Ideally this would use drm_clflush_*(), but implementing that for ARM causes DRM to fail to build as a module since some of the low-level cache maintenance functions aren't exported. Hopefully we can get a suitable API exported on ARM for the next release. The second regression is caused by a mismatch between the hardware pipe number and the CRTC's DRM index. These were used inconsistently, which could cause one code location to call drm_vblank_get() with a different pipe than the corresponding drm_vblank_put(), thereby causing the reference count to become unbalanced. Alexandre also reported a possible race condition related to this, which this series also fixes. * tag 'drm/tegra/for-3.19-rc1-fixes' of git://people.freedesktop.org/~tagr/linux: drm/tegra: dc: Select root window for event dispatch drm/tegra: gem: Use the proper size for GEM objects drm/tegra: gem: Flush buffer objects upon allocation drm/tegra: dc: Fix a potential race on page-flip completion drm/tegra: dc: Consistently use the same pipe drm/irq: Add drm_crtc_vblank_count() drm/irq: Add drm_crtc_handle_vblank() drm/irq: Add drm_crtc_send_vblank_event()

2014-12-22audit: correctly record file names with different path name typesPaul Moore1-4/+10
There is a problem with the audit system when multiple audit records are created for the same path, each with a different path name type. The root cause of the problem is in __audit_inode() when an exact match (both the path name and path name type) is not found for a path name record; the existing code creates a new path name record, but it never sets the path name in this record, leaving it NULL. This patch corrects this problem by assigning the path name to these newly created records. There are many ways to reproduce this problem, but one of the easiest is the following (assuming auditd is running): # mkdir /root/tmp/test # touch /root/tmp/test/567 # auditctl -a always,exit -F dir=/root/tmp/test # touch /root/tmp/test/567 Afterwards, or while the commands above are running, check the audit log and pay special attention to the PATH records. A faulty kernel will display something like the following for the file creation: type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416957442.025:93): cwd="/root/tmp" type=PATH msg=audit(1416957442.025:93): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416957442.025:93): item=1 name=(null) inode=393804 ... nametype=NORMAL type=PATH msg=audit(1416957442.025:93): item=2 name=(null) inode=393804 ... nametype=NORMAL While a patched kernel will show the following: type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416955786.566:89): cwd="/root/tmp" type=PATH msg=audit(1416955786.566:89): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416955786.566:89): item=1 name="test/567" inode=393804 ... nametype=NORMAL This issue was brought up by a number of people, but special credit should go to hujianyang@huawei.com for reporting the problem along with an explanation of the problem and a patch.

2014-12-21ipmi: Finish cleanup of BMC attributesCorey Minyard1-29/+17
The previous cleanup of BMC attributes left a few holes, and if you run with lockdep debugging with a BMC with the proper attributes, you could get a warning. This patch removes all the unused attributes from the BMC structure, since they are all declared in the .data section now. It makes the attributes all static. It fixes the referencing of the attributes in a couple of cases that dynamically added the files depending on BMC information.

2014-12-19audit: use supplied gfp_mask from audit_buffer in kauditd_send_multicast_skbRichard Guy Briggs1-4/+4
Eric Paris explains: Since kauditd_send_multicast_skb() gets called in audit_log_end(), which can come from any context (aka even a sleeping context) GFP_KERNEL can't be used. Since the audit_buffer knows what context it should use, pass that down and use that.

2014-12-19audit: don't attempt to lookup PIDs when changing PID filtering audit rulesPaul Moore1-13/+0
Commit f1dc4867 ("audit: anchor all pid references in the initial pid namespace") introduced a find_vpid() call when adding/removing audit rules with PID/PPID filters; unfortunately this is problematic as find_vpid() only works if there is a task with the associated PID alive on the system. The following commands demonstrate a simple reproducer. # auditctl -D # auditctl -l # autrace /bin/true # auditctl -l This patch resolves the problem by simply using the PID provided by the user without any additional validation, e.g. no calls to check to see if the task/PID exists.

2014-12-20CRIS: Export missing function symbolsJesper Nilsson3-19/+19
strcmp was lost when all other string functions were removed, but we still have an optimized version for this on CRISv32, so any driver built as a module would not have access to this symbol. In a similar manner, we had optimized versions of csum_partial_copy_from_user and __do_clear_user but no exported symbols for them, breaking bunch of other drivers when built as a module. At the same time, move EXPORT_SYMBOL(__copy_user) and EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's located together with the function definition.
