2015-03-19Revert "of: Fix premature bootconsole disable with 'stdout-path'"Peter Hurley1-3/+1
This reverts commit 2fa645cb2703d9b3786d850db815414dfeefa51d. The assumption that at least 1 preferred console will be registered when the stdout-path property is set is invalid, which can result in _no_ consoles.

2015-03-19of: handle both '/' and ':' in path stringsBrian Norris1-6/+1
Commit 106937e8ccdc ("of: fix handling of '/' in options for of_find_node_by_path()") caused a regression in OF handling of stdout-path. While it fixes some cases which have '/' after the ':', it breaks cases where there is more than one '/' *before* the ':'. For example, it breaks this boot string stdout-path = "/rdb/serial@f040ab00:115200"; So rather than doing sequentialized checks (first for '/', then for ':'; or vice versa), to get the correct behavior we need to check for the first occurrence of either one of them. It so happens that the handy strcspn() helper can do just that.

There were regressions seen with commit 106937e8ccdc ("of: fix handling of '/' in options for of_find_node_by_path()"), where we couldn't handle extra '/' before the ':'. Let's test for this now. Confirmed that this test fails without the previous patch and passes when patched. All other tests pass.

2015-03-19of/irq: Fix of_irq_parse_one() returned error codesLaurent Pinchart1-3/+7
The error code paths that require cleanup use a goto to jump to the cleanup code and return an error code. However, the error code variable res, which is initialized to -EINVAL when declared, is then overwritten with the return value of of_parse_phandle_with_args(), and reused as the return code from of_irq_parse_one(). This leads to an undetermined error being returned instead of the expected -EINVAL value. Fix it.

2015-03-19netfilter: restore rule tracing via nfnetlink_logPablo Neira Ayuso5-10/+44
Since fab4085 ("netfilter: log: nf_log_packet() as real unified interface"), the loginfo structure that is passed to nf_log_packet() is used to explicitly indicate the logger type you want to use. This is a problem for people tracing rules through nfnetlink_log since packets are always routed to the NF_LOG_TYPE logger after the aforementioned patch. We can fix this by removing the trace loginfo structures, but that still changes the log level from 4 to 5 for tracing messages and there may be someone relying on this outthere. So let's just introduce a new nf_log_trace() function that restores the former behaviour. Reported-by: Markus Kötter <[email protected]> Signed-off-by: Pablo Neira Ayuso <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes Some urgent regression fixes to booting failures Exynos DRM occured. Summary: - Fix two urgent null pointer dereference bugs in case of enabling or disabling IOMMU. There was two cases to these issues. One is that plane->crtc is accessed by exynos_disable_plane() when device tree binding is broken so device driver tries to release, which means that the mode set operation isn't invoked yet so plane->crtc is still NULL and exynos_disable_plane() will access NULL pointer. This issue is fixed by checking if the plane->crtc is NULL or not in exynos_disable_plane() Other is that fimd_wait_for_vblank() is called to avoid from page fault with IOMMU before the ctx object is created. At this time, fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc is still NULL because exynos_drm_crtc_create() isn't called yet. This issue is fixed by creating a crtc object and setting it to ctx->crtc prior to fimd_wait_for_vblank() call. For more details, you can refer to below an e-mail thread, http://www.spinics.net/lists/linux-samsung-soc/msg42436.html - Remove unnecessary file not used and fix trivial issues. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: fix the initialization order in FIMD drm/exynos: fix typo config name correctly. drm/exynos: Check for NULL dereference of crtc drm/exynos: IS_ERR() vs NULL bug drm/exynos: remove unused files

2015-03-18blkmq: Fix NULL pointer deref when all reserved tags inSam Bradshaw1-2/+4
When allocating from the reserved tags pool, bt_get() is called with a NULL hctx. If all tags are in use, the hw queue is kicked to push out any pending IO, potentially freeing tags, and tag allocation is retried. The problem is that blk_mq_run_hw_queue() doesn't check for a NULL hctx. So we avoid it with a simple NULL hctx test. Tested by hammering mtip32xx with concurrent smartctl/hdparm.

2015-03-18ARM: dts: Fix gpio interrupts for dm816xTony Lindgren2-4/+33
Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree configuration") added basic devices for dm816x, but I was not able to test the GPIO interrupts earlier until I found some suitable pins to test with. We can mux the MMC card detect and write protect pins from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that are also suitable for the MMC subsystem. This turned out several issues that need to be fixed: - I set the GPIO type wrong to be compatible with omap3 instead of omap4. The GPIO controller on dm816x has EOI interrupt register like omap4 and am335x. - I got the GPIO interrupt numbers wrong as each bank has two and we only use one. They need to be set up the same way as on am335x. - The gpio banks are missing interrupt controller related properties. With these changes the GPIO interrupts can be used with the MMC card detect pin, so let's wire that up. Let's also mux all the MMC lines for completeness while at it. For the first GPIO bank I tested using GPMC lines temporarily muxed to GPIOs on the dip switch 10.

radeon_bo_create() calls radeon_ttm_placement_from_domain() before ttm_bo_init() is called. radeon_ttm_placement_from_domain() uses the ttm bo size to determine when to select top down allocation but since the ttm bo is not initialized yet the check is always false. It only took effect when buffers were validated later. It also seemed to regress suspend and resume on some systems possibly due to it not taking effect in radeon_bo_create(). radeon_bo_create() and radeon_ttm_placement_from_domain() need to be reworked substantially for this to be optimally effective.

2015-03-18spi: trigger trace event for message-done before mesg->completeUwe Kleine-König1-2/+3
With spidev the mesg->complete callback points to spidev_complete. Calling this unblocks spidev_sync and so spidev_sync_write finishes. As the struct spi_message just read is a local variable in spidev_sync_write and recording the trace event accesses this message the recording is better done first. The same can happen for spidev_sync_read. This fixes an oops observed on a 3.14-rt system with spidev activity after echo 1 > /sys/kernel/debug/tracing/events/spi/enable .

The set_memory_* functions currently only support module addresses. The addresses are validated using is_module_addr. That function is special though and relies on internal state in the module subsystem to work properly. At the time of module initialization and calling set_memory_*, it's too early for is_module_addr to work properly so it always returns false. Rather than be subject to the whims of the module state, just bounds check against the module virtual address range.

On sun4i-a10, when GPIOs are configured as external interrupt the value for them in the data register does not seem to get updated, so set their mux to input (and restore afterwards) when reading the pin. Missed edges seem to be buffered, so this does not introduce a race condition. I've also tested this on sun5i-a13 and sun7i-a20 and those do not seem to be affected, the input value representation in the data register does seem to correctly get updated to the actual pin value while in irq mode there.

2015-03-18ovl: upper fs should not be R/Ohujianyang1-5/+19
After importing multi-lower layer support, users could mount a r/o partition as the left most lowerdir instead of using it as upperdir. And a r/o upperdir may cause an error like overlayfs: failed to create directory ./workdir/work during mount. This patch check the *s_flags* of upper fs and return an error if it is a r/o partition. The checking of *upper_mnt->mnt_sb->s_flags* can be removed now. This patch also remove /* FIXME: workdir is not needed for a R/O mount */ from ovl_fill_super() because: 1) for upper fs r/o case Setting a r/o partition as upper is prevented, no need to care about workdir in this case. 2) for "mount overlay -o ro" with a r/w upper fs case Users could remount overlayfs to r/w in this case, so workdir should not be omitted.

2015-03-17act_bpf: allow non-default TC_ACT opcodes as BPF exec outcomeDaniel Borkmann1-8/+28
Revisiting commit d23b8ad8ab23 ("tc: add BPF based action") with regards to eBPF support, I was thinking that it might be better to improve return semantics from a BPF program invoked through BPF_PROG_RUN(). Currently, in case filter_res is 0, we overwrite the default action opcode with TC_ACT_SHOT. A default action opcode configured through tc's m_bpf can be: TC_ACT_RECLASSIFY, TC_ACT_PIPE, TC_ACT_SHOT, TC_ACT_UNSPEC, TC_ACT_OK. In cls_bpf, we have the possibility to overwrite the default class associated with the classifier in case filter_res is _not_ 0xffffffff (-1). That allows us to fold multiple [e]BPF programs into a single one, where they would otherwise need to be defined as a separate classifier with its own classid, needlessly redoing parsing work, etc. Similarly, we could do better in act_bpf: Since above TC_ACT* opcodes are exported to UAPI anyway, we reuse them for return-code-to-tc-opcode mapping, where we would allow above possibilities. Thus, like in cls_bpf, a filter_res of 0xffffffff (-1) means that the configured _default_ action is used. Any unkown return code from the BPF program would fail in tcf_bpf() with TC_ACT_UNSPEC. Should we one day want to make use of TC_ACT_STOLEN or TC_ACT_QUEUED, which both have the same semantics, we have the option to either use that as a default action (filter_res of 0xffffffff) or non-default BPF return code. All that will allow us to transparently use tcf_bpf() for both BPF flavours.

2015-03-17KVM: nVMX: mask unrestricted_guest if disabled on L0Radim Krčmář1-2/+5
If EPT was enabled, unrestricted_guest was allowed in L1 regardless of L0. L1 triple faulted when running L2 guest that required emulation. Another side effect was 'WARN_ON_ONCE(vmx->nested.nested_run_pending)' in L0's dmesg: WARNING: CPU: 0 PID: 0 at arch/x86/kvm/vmx.c:9190 nested_vmx_vmexit+0x96e/0xb00 [kvm_intel] () Prevent this scenario by masking SECONDARY_EXEC_UNRESTRICTED_GUEST when the host doesn't have it enabled.

2015-03-18pinctrl: at91: move lock/unlock_as_irq calls into request/releaseBoris Brezillon1-10/+7
The gpiochip_lock_as_irq call can fail and return an error, while the irq_startup is not expected to fail (returns an unsigned int which is not checked by irq core code). irq_request/release_resources functions have been created to address this problem. Move gpiochip_lock/unlock_as_irq calls into irq_request/release_resources functions to prevent using a gpio as an irq if the gpiochip_lock_as_irq call failed.

2015-03-17Btrfs: fix outstanding_extents accounting in DIOJosef Bacik1-2/+35
We are keeping track of how many extents we need to reserve properly based on the amount we want to write, but we were still incrementing outstanding_extents if we wrote less than what we requested. This isn't quite right since we will be limited to our max extent size. So instead lets do something horrible! Keep track of how many outstanding_extents we reserved, and decrement each time we allocate an extent. If we use our entire reserve make sure to jack up outstanding_extents on the inode so the accounting works out properly. Thanks, Reported-by: Filipe Manana <[email protected]> Signed-off-by: Josef Bacik <[email protected]>
2015-03-17Btrfs: add sanity test for outstanding_extents accountingJosef Bacik4-1/+217
I introduced a regression wrt outstanding_extents accounting. These are tricky areas that aren't easily covered by xfstests as we could change MAX_EXTENT_SIZE at any time. So add sanity tests to cover the various conditions that are tricky in order to make sure we don't introduce regressions in the future. Thanks, Signed-off-by: Josef Bacik <[email protected]>
