[PATCH v2] mtd: rawnand: marvell: fix the chip-select DT parsing logic

by Miquel Raynal

The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left. Furthermore, for both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings. Finally, the 'reg' property of a 'nand' node (with the new bindings) gives the IDs of each CS line in use. marvell_nand.c driver first look at the number of CS lines that are present in this property. Better use of_property_count_elems_of_size() than dividing by 4 the size of the number of bytes returned by of_get_property().

[PATCH] gpioib: do not free unrequested descriptors

by Timur Tabi

If the main loop in linehandle_create() encounters an error, it unwinds completely by freeing all previously requested GPIO descriptors. However, if the error occurs in the beginning of the loop before that GPIO is requested, then the exit code attempts to free a null descriptor. If extrachecks is enabled, gpiod_free() triggers a WARN_ON. Instead, keep a separate count of legitimate GPIOs so that only those are freed.

[PATCH v3][for 4.17-rc3] cpufreq / CPPC: Set platform specific transition_delay_us

by Prashanth Prakash

Add support to specify platform specific transition_delay_us instead of using the transition delay derived from PCC. With commit "3d41386d556d: cpufreq: CPPC: Use transition_delay_us depending transition_latency" we are setting transition_delay_us directly and not applying the LATENCY_MULTIPLIER. With this on Qualcomm Centriq we can end up with a very high rate of frequency change requests when using schedutil governor (default rate_limit_us=10 compared to an earlier value of 10000). The PCC subspace describes the rate at which the platform can accept commands on the CPPC's PCC channel. This includes read and write command on the PCC channel that can be used for reasons other than frequency transitions. Moreover the same PCC subspace can be used by multiple freq domains and deriving transition_delay_us from it as we do now can be sub-optimal. Moreover if a platform does not use PCC for desired_perf register then there is no way to compute the transition latency or the delay_us. CPPC does not have a standard defined mechanism to get the transition rate or the latency at the moment. Given the above limitations, it is simpler to have a platform specific transition_delay_us and rely on PCC derived value only if a platform specific value is not available.

Revert f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") from stable trees

by Mika Westerberg

Hi, It seems that commit f5a26acf0162 ("pinctrl: intel: Initialize GPIO properly when used through irqchip") can cause problems on some Skylake systems with Sunrisepoint PCH-H. Namely on certain systems it may turn the backlight PWM pin from native mode to GPIO which makes the screen blank during boot. There is more information here: https://bugzilla.redhat.com/show_bug.cgi?id=1543769 The actual reason is that GPIO numbering used in BIOS is using "Windows" numbers meaning that they don't match the hardware 1:1 and because of this a wrong pin (backlight PWM) is picked and switched to GPIO mode. There is a proper fix for this but since it has quite many dependencies on commits that cannot be considered stable material, I suggest we revert commit f5a26acf0162 from stable trees 4.9, 4.14 and 4.15 to prevent the backlight issue. Thanks!

[PATCH 01/11] PM / Domains: Fix error path during attach in genpd

by Ulf Hansson

In case the PM domain fails to be powered on in genpd_dev_pm_attach(), it returns -EPROBE_DEFER, but keeping the device attached to its PM domain. This leads to problems when the next attempt to attach is re-tried. More precisely, in that situation an -EEXIST error code is returned, because the device already has its PM domain pointer assigned, from the first attempt. Now, because of the sloppy error handling by the existing callers of dev_pm_domain_attach(), probing is allowed to continue when -EEXIST is returned. However, in such case there are no guarantees that the PM domain is powered on by genpd, which may lead to hangs when buses/drivers tried to access their devices. Let's fix this behaviour, simply by detaching the device when powering on fails in genpd_dev_pm_attach().

patch "ARM: amba: Fix race condition with driver_override" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: amba: Fix race condition with driver_override to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

[PATCH] kprobes: Fix random address output of blacklist file

by Thomas Richter

File /sys/kernel/debug/kprobes/blacklist displays random addresses: [root@s8360046 linux]# cat /sys/kernel/debug/kprobes/blacklist 0x0000000047149a90-0x00000000bfcb099a print_type_x8 .... This breaks 'perf probe' which uses the blacklist file to prohibit probes on certain functions by checking the address range. Fix this by printing the correct (unhashed) address. The file mode is read all but this is not an issue as the file hierarchy points out: # ls -ld /sys/ /sys/kernel/ /sys/kernel/debug/ /sys/kernel/debug/kprobes/ /sys/kernel/debug/kprobes/blacklist dr-xr-xr-x 12 root root 0 Apr 19 07:56 /sys/ drwxr-xr-x 8 root root 0 Apr 19 07:56 /sys/kernel/ drwx------ 16 root root 0 Apr 19 06:56 /sys/kernel/debug/ drwxr-xr-x 2 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/ -r--r--r-- 1 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/blacklist Everything in and below /sys/kernel/debug is rwx to root only, no group or others have access.

[PATCH] x86/spectre_v2: Don't check microcode versions when running under hypervisors

by Yi Sun

From: Konrad Rzeszutek Wilk <konrad.wilk(a)oracle.com> commit 36268223c1e9981d6cfc33aff8520b3bde4b8114 upstream. As: 1) It's known that hypervisors lie about the environment anyhow (host mismatch) 2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid "correct" value, it all gets to be very murky when migration happens (do you provide the "new" microcode of the machine?). And in reality the cloud vendors are the ones that should make sure that the microcode that is running is correct and we should just sing lalalala and trust them.

[PATCH v2] input/touchscreen: atmel_mxt_ts: Add correct touchpad button mapping for the Caroline Chromebook.

by Vittorio Gambaletta (VittGam)

This patch adds the correct platform data information for the Caroline Chromebook, so that the mouse button does not get stuck in pressed state after the first click.

patch "ARM: amba: Don't read past the end of sysfs "driver_override" buffer" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: amba: Don't read past the end of sysfs "driver_override" buffer to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

commit 7dac4a1726a9 ("ext4: add validity checks for bitmap block numbers") for stable

by Guenter Roeck

Hi Greg, I see that commit 7dac4a1726a9 ("ext4: add validity checks for bitmap block numbers") is marked for stable, but I don't see it queued for any stable branches. Other ext4 patches from the same time frame (end of March) already made their way into stable. Did this patch get lost, or is it still in your queue ? Thanks, Guenter

[PATCH] net: wireless: ti: wlcore: sdio: allow pm to handle sdio power

by Eyal Reizer

pm_runtime handles sdio power on and power off transitions. An old workaround for trying to control the power explicitly from the driver was in fact causing failures on suspend/resume as the mmc layer already power the module on resume. In case of resume pm_runtime_get sync returns a positive device's usage count causing the driver to try an re-initialize an already initialized device. This was causing sdio bus failure on resume.

[PATCH] mac80211_hwsim: fix use-after-free bug in hwsim_exit_net

commit 8cfd36a0b53aeb4ec21d81eb79706697b84dfc3d upstream. When destroying a net namespace, all hwsim interfaces, which are not created in default namespace are deleted. But the async deletion of the interfaces could last longer than the actual destruction of the namespace, which results to an use after free bug. Therefore use synchronous deletion in this case.

[PATCH 2/3] mtd: rawnand: marvell: fix CS pin count with old bindings

by Miquel Raynal

For both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings.

[PATCH 1/3] mtd: rawnand: marvell: fix the chip-select DT parsing logic

by Miquel Raynal

The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left.

This isn't the first time I've seen patches backported that simply don't need to be, or shouldn't be. In one case a few years back the patch had a fixes tag, but it still wasn't important to backport, which is why I left off the Cc stable, and in fact it broke something. TBH its a bit distracting having to review such patches, which I've already looked at before, determined there's no need for a backport, and subsequently paged out of my head. Stable folk: is there already (and should there be) a defined mechanism to record that a given patch is: 1) not suitable/worthwhile to backport (e.g. even though it might have a Fixes tag or use the word "fix"). 2) OR it would require a bit more human effort to backport (perhaps it applies cleanly but would be expected not to build/work) and probably shouldn't be attempted automatically. 3) OR it probably isn't worth backporting and is risky to do so, and so should only be carefully attempted if somebody actually complains. other than simply stating it in prose in the commit message?

[PATCH 2/2] ata: ahci: mvebu: override ahci_stop_engine for mvebu AHCI

by xswang＠marvell.com

From: Evan Wang <xswang(a)marvell.com> There is an issue(Errata Ref#226) that the SATA can not be detected via SATA Port-MultiPlayer(PMP) with following error log: ata1.15: PMP product ID mismatch ata1.15: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0' ata1.15: PMP revalidation failed (errno=-19) After debugging, the reason is found that the value Port-x FIS-based Switching Control(PxFBS@0x40) become wrong. According to design, the bits[11:8, 0] of register PxFBS are cleared when Port Command and Status (0x18) bit[0] changes its value from 1 to 0, i.e. falling edge of Port Command and Status bit[0] sends PULSE that resets PxFBS bits[11:8; 0]. So it needs a mvebu SATA WA to save the port PxFBS register before PxCMD ST write and restore it afterwards.

[PATCH] [v2] x86: ipc: fix x32 version of shmid64_ds and msqid64_ds

by Arnd Bergmann

A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout (as seen from user space) a few years ago: Originally, __BITS_PER_LONG was defined as 64 on x32, so we did not have padding after the 64-bit __kernel_time_t fields, After __BITS_PER_LONG got changed to 32, applications would observe extra padding. In other parts of the uapi headers we seem to have a mix of those expecting either 32 or 64 on x32 applications, so we can't easily revert the path that broke these two structures. Instead, this patch decouples x32 from the other architectures and moves it back into arch specific headers, partially reverting the even older commit 73a2d096fdf2 ("x86: remove all now-duplicate header files"). It's not clear whether this ever made any difference, since at least glibc carries its own (correct) copy of both of these header files, so possibly no application has ever observed the definitions here. Based on a suggestion from H.J. Lu, I tried out the tool from https://github.com/hjl-tools/linux-header to find other such bugs, which pointed out the same bug in statfs(), which also has a separate (correct) copy in glibc.

[PATCH] mac80211_hwsim: fix use-after-free bug in hwsim_exit_net

by Benjamin Beichler

commit 8cfd36a0b53aeb4ec21d81eb79706697b84dfc3d upstream. When destroying a net namespace, all hwsim interfaces, which are not created in default namespace are deleted. But the async deletion of the interfaces could last longer than the actual destruction of the namespace, which results to an use after free bug. Therefore use synchronous deletion in this case. Fixes: 100cb9ff40e0 ("mac80211_hwsim: Allow managing radios from non-initial namespaces") Reported-by: syzbot+70ce058e01259de7bb1d(a)syzkaller.appspotmail.com Signed-off-by: Benjamin Beichler <benjamin.beichler(a)uni-rostock.de> Signed-off-by: Johannes Berg <johannes.berg(a)intel.com> --- drivers/net/wireless/mac80211_hwsim.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/net/wireless/mac80211_hwsim.c b/drivers/net/wireless/mac80211_hwsim.c index 4182c3775a72..2681b5339810 100644 --- a/drivers/net/wireless/mac80211_hwsim.c +++ b/drivers/net/wireless/mac80211_hwsim.c @@ -3346,8 +3346,11 @@ static void __net_exit hwsim_exit_net(struct net *net) continue; list_del(&data->list); - INIT_WORK(&data->destroy_work, destroy_radio); - schedule_work(&data->destroy_work); + spin_unlock_bh(&hwsim_radio_lock); + mac80211_hwsim_del_radio(data, wiphy_name(data->hw->wiphy), + NULL); + spin_lock_bh(&hwsim_radio_lock); + } spin_unlock_bh(&hwsim_radio_lock); } -- 2.17.0

[PATCH] drm/i915/bxt, glk: Increase PCODE timeouts during CDCLK freq changing

by Imre Deak

commit 5e1df40f40ee45a97bb1066c3d71f0ae920a9672 upstream. Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602c815 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> # v4.9 Acked-by: Chris Wilson <chris(a)chris-wilson.co.uk> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326 Reviewed-by: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Signed-off-by: Imre Deak <imre.deak(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180130142939.17983-1-imre.d… (cherry picked from commit e76019a81921e87a4d9e7b3d86102bc708a6c227) Signed-off-by: Rodrigo Vivi <rodrigo.vivi(a)intel.com> (Rebased for v4.9 stable tree due to upstream intel_cdclk.c, cdclk_state and pcu_lock change) Signed-off-by: Imre Deak <imre.deak(a)intel.com> --- drivers/gpu/drm/i915/i915_drv.h | 6 +++++- drivers/gpu/drm/i915/intel_display.c | 9 +++++---- drivers/gpu/drm/i915/intel_pm.c | 6 +++--- 3 files changed, 13 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 36a665f0e5c9..e23748cca0c0 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -3681,7 +3681,11 @@ extern void intel_display_print_error_state(struct drm_i915_error_state_buf *e, struct intel_display_error_state *error); int sandybridge_pcode_read(struct drm_i915_private *dev_priv, u32 mbox, u32 *val); -int sandybridge_pcode_write(struct drm_i915_private *dev_priv, u32 mbox, u32 val); +int sandybridge_pcode_write_timeout(struct drm_i915_private *dev_priv, u32 mbox, + u32 val, int timeout_us); +#define sandybridge_pcode_write(dev_priv, mbox, val) \ + sandybridge_pcode_write_timeout(dev_priv, mbox, val, 500) + int skl_pcode_request(struct drm_i915_private *dev_priv, u32 mbox, u32 request, u32 reply_mask, u32 reply, int timeout_base_ms); diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index ce32303b3013..c185625d67f2 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -6012,8 +6012,8 @@ static void bxt_set_cdclk(struct drm_i915_private *dev_priv, int cdclk) /* Inform power controller of upcoming frequency change */ mutex_lock(&dev_priv->rps.hw_lock); - ret = sandybridge_pcode_write(dev_priv, HSW_PCODE_DE_WRITE_FREQ_REQ, - 0x80000000); + ret = sandybridge_pcode_write_timeout(dev_priv, HSW_PCODE_DE_WRITE_FREQ_REQ, + 0x80000000, 2000); mutex_unlock(&dev_priv->rps.hw_lock); if (ret) { @@ -6044,8 +6044,9 @@ static void bxt_set_cdclk(struct drm_i915_private *dev_priv, int cdclk) I915_WRITE(CDCLK_CTL, val); mutex_lock(&dev_priv->rps.hw_lock); - ret = sandybridge_pcode_write(dev_priv, HSW_PCODE_DE_WRITE_FREQ_REQ, - DIV_ROUND_UP(cdclk, 25000)); + ret = sandybridge_pcode_write_timeout(dev_priv, + HSW_PCODE_DE_WRITE_FREQ_REQ, + DIV_ROUND_UP(cdclk, 25000), 2000); mutex_unlock(&dev_priv->rps.hw_lock); if (ret) { diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index 49de4760cc16..05427d292457 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -7913,8 +7913,8 @@ int sandybridge_pcode_read(struct drm_i915_private *dev_priv, u32 mbox, u32 *val return 0; } -int sandybridge_pcode_write(struct drm_i915_private *dev_priv, - u32 mbox, u32 val) +int sandybridge_pcode_write_timeout(struct drm_i915_private *dev_priv, + u32 mbox, u32 val, int timeout_us) { int status; @@ -7935,7 +7935,7 @@ int sandybridge_pcode_write(struct drm_i915_private *dev_priv, if (intel_wait_for_register_fw(dev_priv, GEN6_PCODE_MAILBOX, GEN6_PCODE_READY, 0, - 500)) { + timeout_us)) { DRM_ERROR("timeout waiting for pcode write (%d) to finish\n", mbox); return -ETIMEDOUT; } -- 2.13.2

[PATCHv3] mtd: spi-nor: Fix Cadence QSPI page fault kernel panic

by thor.thayer＠linux.intel.com

From: Thor Thayer <thor.thayer(a)linux.intel.com> The current Cadence QSPI driver caused a kernel panic when loading a Root Filesystem from QSPI. The problem was caused by reading more bytes than needed because the QSPI operated on 4 bytes at a time. <snip> [ 7.947754] spi_nor_read[1048]:from 0x037cad74, len 1 [bfe07fff] [ 7.956247] cqspi_read[910]:offset 0x58502516, buffer=bfe07fff [ 7.956247] [ 7.966046] Unable to handle kernel paging request at virtual address bfe08002 [ 7.973239] pgd = eebfc000 [ 7.975931] [bfe08002] *pgd=2fffb811, *pte=00000000, *ppte=00000000 </snip> Notice above how only 1 byte needed to be read but by reading 4 bytes into the end of a mapped page, an unrecoverable page fault occurred. This patch uses a temporary buffer to hold the 4 bytes read and then copies only the bytes required into the buffer. A min() function is used to limit the length to prevent buffer overflows.

[PATCH 1/3] cfi_cmdset_0001: Do not allow read/write to suspend erase block.

by Joakim Tjernlund

From: Joakim Tjernlund <joakim.tjernlund(a)transmode.se> Currently it is possible to read and/or write to suspend EB's. Writing /dev/mtdX or /dev/mtdblockX from several processes may break the flash state machine.

FAILED: patch "[PATCH] mm, vmscan: Allow preallocating memory for" failed to apply to 4.14-stable tree

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 8e04944f0ea8b838399049bdcda920ab36ae3b04 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp> Date: Wed, 4 Apr 2018 19:53:07 +0900 Subject: [PATCH] mm,vmscan: Allow preallocating memory for register_shrinker(). syzbot is catching so many bugs triggered by commit 9ee332d99e4d5a97 ("sget(): handle failures of register_shrinker()"). That commit expected that calling kill_sb() from deactivate_locked_super() without successful fill_super() is safe, but the reality was different; some callers assign attributes which are needed for kill_sb() after sget() succeeds. For example, [1] is a report where sb->s_mode (which seems to be either FMODE_READ | FMODE_EXCL | FMODE_WRITE or FMODE_READ | FMODE_EXCL) is not assigned unless sget() succeeds. But it does not worth complicate sget() so that register_shrinker() failure path can safely call kill_block_super() via kill_sb().

[PATCH 0/2] usb: typec: fixes

by Heikki Krogerus

Hi, I got two separate fixes here. First one will fix an issue with ucsi where the driver may timeout if EC is under heavy load, and the second an issue with tps6598x when used with plain I2C adapters.

[PATCH 03/20] drm/amd/display: Disallow enabling CRTC without primary plane with FB

by Harry Wentland

The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. Since DC is currently not equipped to handle this we need to fail such a commit, otherwise we might see a corrupted screen. This is based on Shirish's previous approach but avoids adding all planes to the new atomic state which leads to a full update in DC for any commit, and is not what we intend. Theoretically DM should be able to deal with states with fully populated planes, even for simple updates, such as cursor updates. This should still be addressed in the future.

[PATCH] arm64: export tishift functions to modules

by Jason A. Donenfeld

Otherwise modules that use these arithmetic operations will fail to link. We accomplish this with EXPORT_SYMBOL in the .S file, but because of symbol versioning, we actually need to have a declaration of these too in C. So, we introduce asm-prototypes.h, which is the same file name and technique used for similar reasons in the m68k arch tree. While we're at it, we also fix this up to use SPDX, and I personally choose to relicense this as GPL2||BSD so that these symbols don't need to be export_symbol_gpl, so all modules can use the routines, since these are important general purpose compiler-generated function calls.

Wouldn't this potentially still cause problems if the secure erase takes longer than max_retries * scmd_tmo. I.e. the command timing out by default after 180 seconds as in https://www.spinics.net/lists/linux-block/msg24837.html ? The fix approach here seems to also handle this gracefully. -- Mit freundlichen Grüßen / Kind regards Steffen Maier Linux on z Systems Development IBM Deutschland Research & Development GmbH Vorsitzende des Aufsichtsrats: Martina Koederitz Geschaeftsfuehrung: Dirk Wittkopp Sitz der Gesellschaft: Boeblingen Registergericht: Amtsgericht Stuttgart, HRB 243294

[PATCH 1/7] ARM: dts: sun8i: h3: fix ALL-H3-CC H3 ver VCC-1V2 regulator voltage

[PATCH] drm/i915/bxt, glk: Increase PCODE timeouts during CDCLK freq changing

by Imre Deak

commit 5e1df40f40ee45a97bb1066c3d71f0ae920a9672 upstream. Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602c815 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> # v4.14 Acked-by: Chris Wilson <chris(a)chris-wilson.co.uk> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326 Reviewed-by: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Signed-off-by: Imre Deak <imre.deak(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180130142939.17983-1-imre.d… (cherry picked from commit e76019a81921e87a4d9e7b3d86102bc708a6c227) Signed-off-by: Rodrigo Vivi <rodrigo.vivi(a)intel.com> (Rebased for v4.14 stable tree due to upstream cdclk_state and pcu_lock change) Signed-off-by: Imre Deak <imre.deak(a)intel.com> --- drivers/gpu/drm/i915/i915_drv.h | 6 +++++- drivers/gpu/drm/i915/intel_cdclk.c | 22 +++++++++++++++++----- drivers/gpu/drm/i915/intel_pm.c | 6 +++--- 3 files changed, 25 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 3f818412765c..51411894d2cd 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -3995,7 +3995,11 @@ extern void intel_display_print_error_state(struct drm_i915_error_state_buf *e, struct intel_display_error_state *error); int sandybridge_pcode_read(struct drm_i915_private *dev_priv, u32 mbox, u32 *val); -int sandybridge_pcode_write(struct drm_i915_private *dev_priv, u32 mbox, u32 val); +int sandybridge_pcode_write_timeout(struct drm_i915_private *dev_priv, u32 mbox, + u32 val, int timeout_us); +#define sandybridge_pcode_write(dev_priv, mbox, val) \ + sandybridge_pcode_write_timeout(dev_priv, mbox, val, 500) + int skl_pcode_request(struct drm_i915_private *dev_priv, u32 mbox, u32 request, u32 reply_mask, u32 reply, int timeout_base_ms); diff --git a/drivers/gpu/drm/i915/intel_cdclk.c b/drivers/gpu/drm/i915/intel_cdclk.c index 26a8dcd2c549..47ad24229c78 100644 --- a/drivers/gpu/drm/i915/intel_cdclk.c +++ b/drivers/gpu/drm/i915/intel_cdclk.c @@ -1289,10 +1289,15 @@ static void bxt_set_cdclk(struct drm_i915_private *dev_priv, break; } - /* Inform power controller of upcoming frequency change */ mutex_lock(&dev_priv->rps.hw_lock); - ret = sandybridge_pcode_write(dev_priv, HSW_PCODE_DE_WRITE_FREQ_REQ, - 0x80000000); + /* + * Inform power controller of upcoming frequency change.

[PULL 1/1] vfio: ccw: fix cleanup if cp_prefetch fails

by Cornelia Huck

From: Halil Pasic <pasic(a)linux.vnet.ibm.com> If the translation of a channel program fails, we may end up attempting to clean up (free, unpin) stuff that never got translated (and allocated, pinned) in the first place. By adjusting the lengths of the chains accordingly (so the element that failed, and all subsequent elements are excluded) cleanup activities based on false assumptions can be avoided. Let's make sure cp_free works properly after cp_prefetch returns with an error by setting ch_len of a ccw chain to the number of the translated CCWs on that chain.

[PATCH v2] rtlwifi: cleanup 8723be ant_sel definition

by pkshih＠realtek.com

From: Ping-Ke Shih <pkshih(a)realtek.com> The module parameter ant_sel is used to control antenna number and path. There is an existing enum ANT_{X2,X1} defined the antenna number, so add a new enum ANT_{MAIN,AUX} to make it readable. After this work, incorrect given values depend on ant_sel were exposed, so refill values according following definition: ant_sel ant_num ant_path print_label 1 ANT_X1 ANT_AUX #2 2 ANT_X2 ANT_MAIN #1 Then, a workaround resulted from the incorrect values in halbtcoutsrc.c was removed. These is a existing bug in the workaround while ant_sel=2, but the case is rare use so user is hard to observe this bug. The experimental results with single antenna connected to specific path are in following: ant_sel ANT_MAIN(#1) ANT_AUX(#2) 0 -8 -62 1 -62 -10 2 -6 -60 Signed-off-by: Ping-Ke Shih <pkshih(a)realtek.com> Cc: Stable <stable(a)vger.kernel.org> # 4.7+ Reviewed-by: Larry Finger <Larry.Finger(a)lwfinger.net> --- v2: Add more description about fixed bugs in end of first paragraph. --- .../net/wireless/realtek/rtlwifi/btcoexist/halbtcoutsrc.c | 15 --------------- drivers/net/wireless/realtek/rtlwifi/rtl8723be/hw.c | 11 +++++++---- drivers/net/wireless/realtek/rtlwifi/wifi.h | 5 +++++ 3 files changed, 12 insertions(+), 19 deletions(-) diff --git a/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtcoutsrc.c b/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtcoutsrc.c index e0f9985582f9..738a7ea7dc4a 100644 --- a/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtcoutsrc.c +++ b/drivers/net/wireless/realtek/rtlwifi/btcoexist/halbtcoutsrc.c @@ -158,16 +158,6 @@ static u8 halbtc_get_wifi_central_chnl(struct btc_coexist *btcoexist) static u8 rtl_get_hwpg_single_ant_path(struct rtl_priv *rtlpriv) { - struct rtl_mod_params *mod_params = rtlpriv->cfg->mod_params; - - /* override ant_num / ant_path */ - if (mod_params->ant_sel) { - rtlpriv->btcoexist.btc_info.ant_num = - (mod_params->ant_sel == 1 ?

Re: [GIT PULL] commits for Linux 4.14

by Sasha Levin

Ping on these? Also, at this point I seem to be building these trees faster than we deal with them (so for example, 4.15 has about 600 patches that didn't make it in before it went EOL). I also have about 600+ outstanding patches for 4.14 queued up. Would you be ok with making these batches bigger?

RE: [PATCH] [SCSI] mpt3sas: Fix secure erase premature termination (v4)

by Igor Rybak

Hi, We are running kernel 4.4.0-22 and the patch below does not seem to be present in the mpt3sas driver. Can you please confirm? As a reminder the patch was related to a Security Erase ATA command that requires a very long timeout like 100 minutes or more and the drive retains a busy status. And the driver should not try to send other commands or reset the drive. Thanks, Igor Rybak CTO MediaClone Inc 6900 Canby Ave Ste 107 Reseda, CA 91335 USA +1-818-654-6286 ________________________________________ From: Sreekanth Reddy [sreekanth.reddy(a)broadcom.com] Sent: Thursday, November 10, 2016 8:38 PM To: Andrey Grodzovsky Cc: PDL-MPT-FUSIONLINUX; Igor Rybak; Ezra Kohavi; linux-scsi(a)vger.kernel.org; Sathya Prakash; Chaitra P B; Suganath Prabu Subramani; Hannes Reinecke; stable(a)vger.kernel.org Subject: Re: [PATCH] [SCSI] mpt3sas: Fix secure erase premature termination (v4) On Thu, Nov 10, 2016 at 8:05 PM, Andrey Grodzovsky <andrey2805(a)gmail.com> wrote: > Problem: > This is a work around for a bug with LSI Fusion MPT SAS2 when > pefroming secure erase.

The first message is offloaded to hv_eject_device_work(), and the second is offloaded to pci_devices_present_work(). Both the paths can be running list_del(&hpdev->list_entry), causing general protection fault, because system_wq can run them concurrently. The patch eliminates the race condition. Since access to present/eject work items is serialized, we do not need the hbus->enum_sem anymore, so remove it.

[RHEL7.6 PATCH 22/37] Drivers: hv: vmbus: Fix a rescind issue

by Mohammed Gamal

The current rescind processing code will not correctly handle the case where the host immediately rescinds a channel that has been offerred.

[PATCH] mtd: spi-nor: Fix Cadence QSPI page fault kernel panic

by thor.thayer＠linux.intel.com

From: Thor Thayer <thor.thayer(a)linux.intel.com> The current Cadence QSPI driver caused a kernel panic when loading a Root Filesystem from QSPI.

[PATCH] RDMA/cxgb4: release hw resources on device removal

by Raju Rangoju

The c4iw_rdev_close() logic was not releasing all the hw resources (PBL and RQT memory) during the device removal event (driver unload / system reboot). This can cause panic in gen_pool_destroy(). The module remove function will wait for all the hw resources to be released during the device removal event.

[PATCH 4.14/4.16 v2] writeback: safer lock nesting

by Nathan Chancellor

From: Greg Thelen <gthelen(a)google.com> commit 2e898e4c0a3897ccd434adac5abb8330194f527b upstream. lock_page_memcg()/unlock_page_memcg() use spin_lock_irqsave/restore() if the page's memcg is undergoing move accounting, which occurs when a process leaves its memcg for a new one that has memory.move_charge_at_immigrate set. unlocked_inode_to_wb_begin,end() use spin_lock_irq/spin_unlock_irq() if the given inode is switching writeback domains. Switches occur when enough writes are issued from a new domain. This existing pattern is thus suspicious: lock_page_memcg(page); unlocked_inode_to_wb_begin(inode, &locked); ... unlocked_inode_to_wb_end(inode, locked); unlock_page_memcg(page); If both inode switch and process memcg migration are both in-flight then unlocked_inode_to_wb_end() will unconditionally enable interrupts while still holding the lock_page_memcg() irq spinlock. This suggests the possibility of deadlock if an interrupt occurs before unlock_page_memcg(). truncate __cancel_dirty_page lock_page_memcg unlocked_inode_to_wb_begin unlocked_inode_to_wb_end <interrupts mistakenly enabled> <interrupt> end_page_writeback test_clear_page_writeback lock_page_memcg <deadlock> unlock_page_memcg Due to configuration limitations this deadlock is not currently possible because we don't mix cgroup writeback (a cgroupv2 feature) and memory.move_charge_at_immigrate (a cgroupv1 feature). If the kernel is hacked to always claim inode switching and memcg moving_account, then this script triggers lockup in less than a minute: cd /mnt/cgroup/memory mkdir a b echo 1 > a/memory.move_charge_at_immigrate echo 1 > b/memory.move_charge_at_immigrate ( echo $BASHPID > a/cgroup.procs while true; do dd if=/dev/zero of=/mnt/big bs=1M count=256 done ) & while true; do sync done & sleep 1h & SLEEP=$! while true; do echo $SLEEP > a/cgroup.procs echo $SLEEP > b/cgroup.procs done The deadlock does not seem possible, so it's debatable if there's any reason to modify the kernel. I suggest we should to prevent future surprises. And Wang Long said "this deadlock occurs three times in our environment", so there's more reason to apply this, even to stable. Stable 4.4 has minor conflicts applying this patch.

Hi Greg, Commit 7dac4a1726a9 ("ext4: add validity checks for bitmap block numbers") seems to be the cause of the regression reported here: https://marc.info/?l=linux-ext4&m=152416385122029&w=2 ext4 folks are probably busy at LSF, so no reply yet. Should this commit be held until we get word from Ted? Please excuse broken threading. Thanks, Ilya

[PATCH] drm/i915/bxt, glk: Increase PCODE timeouts during CDCLK freq changing

by Imre Deak

commit 5e1df40f40ee45a97bb1066c3d71f0ae920a9672 upstream. Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602c815 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> # v4.15 Acked-by: Chris Wilson <chris(a)chris-wilson.co.uk> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326 Reviewed-by: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Signed-off-by: Imre Deak <imre.deak(a)intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180130142939.17983-1-imre.d… (cherry picked from commit e76019a81921e87a4d9e7b3d86102bc708a6c227) Signed-off-by: Rodrigo Vivi <rodrigo.vivi(a)intel.com> (Rebased for v4.15 stable tree due to upstream s/DIV_ROUND_UP(cdclk, 25000)/cdclk_state->voltage_level/ change ) Signed-off-by: Imre Deak <imre.deak(a)intel.com> --- drivers/gpu/drm/i915/i915_drv.h | 6 +++++- drivers/gpu/drm/i915/intel_cdclk.c | 22 +++++++++++++++++----- drivers/gpu/drm/i915/intel_pm.c | 6 +++--- 3 files changed, 25 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index e143004e66d5..ffc75271bf7e 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -4140,7 +4140,11 @@ extern void intel_display_print_error_state(struct drm_i915_error_state_buf *e, struct intel_display_error_state *error); int sandybridge_pcode_read(struct drm_i915_private *dev_priv, u32 mbox, u32 *val); -int sandybridge_pcode_write(struct drm_i915_private *dev_priv, u32 mbox, u32 val); +int sandybridge_pcode_write_timeout(struct drm_i915_private *dev_priv, u32 mbox, + u32 val, int timeout_us); +#define sandybridge_pcode_write(dev_priv, mbox, val) \ + sandybridge_pcode_write_timeout(dev_priv, mbox, val, 500) + int skl_pcode_request(struct drm_i915_private *dev_priv, u32 mbox, u32 request, u32 reply_mask, u32 reply, int timeout_base_ms); diff --git a/drivers/gpu/drm/i915/intel_cdclk.c b/drivers/gpu/drm/i915/intel_cdclk.c index 60cf4e58389a..658f681eb927 100644 --- a/drivers/gpu/drm/i915/intel_cdclk.c +++ b/drivers/gpu/drm/i915/intel_cdclk.c @@ -1284,10 +1284,15 @@ static void bxt_set_cdclk(struct drm_i915_private *dev_priv, break; } - /* Inform power controller of upcoming frequency change */ + /* + * Inform power controller of upcoming frequency change.
