Re: [PATCH] mm, page_alloc: skip ->watermark_boost for atomic order-0 allocations-fix

by Ralph Siemsen

Hi, Please consider applying the patch from this thread to 5.8.y: commit f80b08fc44536a311a9f3182e50f318b79076425 The fix should also go into 5.4.y, however the patch needs some minor adjustments due to surrounding context differences. Attached below is a version I have tested against 5.4.71. This solves a "page allocation failure" error that can be reproduced both on physical hardware, and also under qemu-system-arm. The test consists of repeatedly running md5sum on a large file. In my tests the file contains 1GB of random data, while the system has only 256MB RAM. No other tasks are running or consuming significant memory. After some time (between 1 and 200 iterations) the kernel reports a page allocation failure. Additional failures occur fairly quickly thereafter. The md5sum is correctly computed in each case. The OOM is not invoked. The backtrace shows a 0-order GFP_ATOMIC was requested, with quite a bit of memory available, and yet the allocation fails. Similar error also occurs when "md5sum" is replaced by "scp" or "nc". The backtrace again shows a 0-order with GFP_ATOMIC that fails, with plenty of memory available according to the Mem-Info dump. The problem does not occur under 4.9.y or 4.19.y. Bisction has found that the problem started to occur with 688fcbfc06e4 ("mm/vmalloc: modify struct vmap_area to reduce its size") during the 5.4 dev cycle. I can provide additional logs and details if interested. Thanks, Ralph Below is the f80b08fc445 commit, tweaked to apply to 5.4.y. From: Charan Teja Reddy <charante(a)codeaurora.org> Subject: [PATCH] mm, page_alloc: skip ->waternark_boost for atomic order-0 allocations [upstream commit f80b08fc44536a311a9f3182e50f318b79076425 with context adjusted to match linux-5.4.y] When boosting is enabled, it is observed that rate of atomic order-0 allocation failures are high due to the fact that free levels in the system are checked with ->watermark_boost offset. This is not a problem for sleepable allocations but for atomic allocations which looks like regression. This problem is seen frequently on system setup of Android kernel running on Snapdragon hardware with 4GB RAM size. When no extfrag event occurred in the system, ->watermark_boost factor is zero, thus the watermark configurations in the system are: _watermark = ( [WMARK_MIN] = 1272, --> ~5MB [WMARK_LOW] = 9067, --> ~36MB [WMARK_HIGH] = 9385), --> ~38MB watermark_boost = 0 After launching some memory hungry applications in Android which can cause extfrag events in the system to an extent that ->watermark_boost can be set to max i.e. default boost factor makes it to 150% of high watermark. _watermark = ( [WMARK_MIN] = 1272, --> ~5MB [WMARK_LOW] = 9067, --> ~36MB [WMARK_HIGH] = 9385), --> ~38MB watermark_boost = 14077, -->~57MB With default system configuration, for an atomic order-0 allocation to succeed, having free memory of ~2MB will suffice. But boosting makes the min_wmark to ~61MB thus for an atomic order-0 allocation to be successful system should have minimum of ~23MB of free memory(from calculations of zone_watermark_ok(), min = 3/4(min/2)). But failures are observed despite system is having ~20MB of free memory. In the testing, this is reproducible as early as first 300secs since boot and with furtherlowram configurations(<2GB) it is observed as early as first 150secs since boot. These failures can be avoided by excluding the ->watermark_boost in watermark caluculations for atomic order-0 allocations.

[PATCH v2 6/6] thermal: tegra: Avoid setting edp_irq when not relevant

by Nicolas Chauvet

According to the binding, the edp_irq is not available on tegra124/132 This commit moves the initialization of tegra->edp_irq after the introduced has_edp_irq condition. This will have the following effects: - soctherm_interrupts_init will not return prematurely with unfinished thermal_irq initialization on tegra124 and tegra132 - edp_irq initialization will be done only when relevant As a result, this will clear the following error on jetson-tk1 : kernel: tegra_soctherm 700e2000.thermal-sensor: IRQ index 1 not found v2: * Use .has_edp_irq boolean instead of of_compatible * Switch subject prefix to use thermal instead of ARM Fixes: 4a04beb1bf2e (thermal: tegra: add support for EDP IRQ) Cc: stable(a)vger.kernel.org Signed-off-by: Nicolas Chauvet <kwizart(a)gmail.com> --- drivers/thermal/tegra/soctherm.c | 38 +++++++++++++---------- drivers/thermal/tegra/soctherm.h | 1 + drivers/thermal/tegra/tegra124-soctherm.c | 1 + drivers/thermal/tegra/tegra132-soctherm.c | 1 + drivers/thermal/tegra/tegra210-soctherm.c | 1 + 5 files changed, 26 insertions(+), 16 deletions(-) diff --git a/drivers/thermal/tegra/soctherm.c b/drivers/thermal/tegra/soctherm.c index 66e0639da4bf..0c79e033e7ea 100644 --- a/drivers/thermal/tegra/soctherm.c +++ b/drivers/thermal/tegra/soctherm.c @@ -2025,12 +2025,6 @@ static int soctherm_interrupts_init(struct platform_device *pdev, return 0; } - tegra->edp_irq = platform_get_irq(pdev, 1); - if (tegra->edp_irq < 0) { - dev_dbg(&pdev->dev, "get 'edp_irq' failed.\n"); - return 0; - } - ret = devm_request_threaded_irq(&pdev->dev, tegra->thermal_irq, soctherm_thermal_isr, @@ -2043,16 +2037,28 @@ static int soctherm_interrupts_init(struct platform_device *pdev, return ret; } - ret = devm_request_threaded_irq(&pdev->dev, - tegra->edp_irq, - soctherm_edp_isr, - soctherm_edp_isr_thread, - IRQF_ONESHOT, - "soctherm_edp", - tegra); - if (ret < 0) { - dev_err(&pdev->dev, "request_irq 'edp_irq' failed.\n"); - return ret; + /* Initialize edp_irq when available */ + if (tegra->soc->has_edp_irq) { + /* get IRQ */ + + tegra->edp_irq = platform_get_irq(pdev, 1); + if (tegra->edp_irq < 0) { + dev_dbg(&pdev->dev, "get 'edp_irq' failed.\n"); + return 0; + } + + /* request IRQ */ + ret = devm_request_threaded_irq(&pdev->dev, + tegra->edp_irq, + soctherm_edp_isr, + soctherm_edp_isr_thread, + IRQF_ONESHOT, + "soctherm_edp", + tegra); + if (ret < 0) { + dev_err(&pdev->dev, "request_irq 'edp_irq' failed.\n"); + return ret; + } } return 0; diff --git a/drivers/thermal/tegra/soctherm.h b/drivers/thermal/tegra/soctherm.h index 70501e73d586..b93cfdd06e5d 100644 --- a/drivers/thermal/tegra/soctherm.h +++ b/drivers/thermal/tegra/soctherm.h @@ -128,6 +128,7 @@ struct tegra_soctherm_soc { const int thresh_grain; const unsigned int bptt; const bool use_ccroc; + const bool has_edp_irq; struct tsensor_group_thermtrips *thermtrips; }; diff --git a/drivers/thermal/tegra/tegra124-soctherm.c b/drivers/thermal/tegra/tegra124-soctherm.c index 20ad27f4d1a1..c8c8231f6cdd 100644 --- a/drivers/thermal/tegra/tegra124-soctherm.c +++ b/drivers/thermal/tegra/tegra124-soctherm.c @@ -216,4 +216,5 @@ const struct tegra_soctherm_soc tegra124_soctherm = { .thresh_grain = TEGRA124_THRESH_GRAIN, .bptt = TEGRA124_BPTT, .use_ccroc = false, + .has_edp_irq = false, }; diff --git a/drivers/thermal/tegra/tegra132-soctherm.c b/drivers/thermal/tegra/tegra132-soctherm.c index b76308fdad9e..1bc9481de5fc 100644 --- a/drivers/thermal/tegra/tegra132-soctherm.c +++ b/drivers/thermal/tegra/tegra132-soctherm.c @@ -216,4 +216,5 @@ const struct tegra_soctherm_soc tegra132_soctherm = { .thresh_grain = TEGRA132_THRESH_GRAIN, .bptt = TEGRA132_BPTT, .use_ccroc = true, + .has_edp_irq = false, }; diff --git a/drivers/thermal/tegra/tegra210-soctherm.c b/drivers/thermal/tegra/tegra210-soctherm.c index d0ff793f18c5..2b09c8a811d0 100644 --- a/drivers/thermal/tegra/tegra210-soctherm.c +++ b/drivers/thermal/tegra/tegra210-soctherm.c @@ -224,5 +224,6 @@ const struct tegra_soctherm_soc tegra210_soctherm = { .thresh_grain = TEGRA210_THRESH_GRAIN, .bptt = TEGRA210_BPTT, .use_ccroc = false, + .has_edp_irq = true, .thermtrips = tegra210_tsensor_thermtrips, }; -- 2.25.4

[PATCH] ext4: Fix checksum errors with indexed dirs

by Jan Kara

DIR_INDEX has been introduced as a compat ext4 feature. That means that even kernels / tools that don't understand the feature may modify the filesystem. This works because for kernels not understanding indexed dir format, internal htree nodes appear just as empty directory entries. Index dir aware kernels then check the htree structure is still consistent before using the data. This all worked reasonably well until metadata checksums were introduced. The problem is that these effectively made DIR_INDEX only ro-compatible because internal htree nodes store checksums in a different place than normal directory blocks. Thus any modification ignorant to DIR_INDEX (or just clearing EXT4_INDEX_FL from the inode) will effectively cause checksum mismatch and trigger kernel errors. So we have to be more careful when dealing with indexed directories on filesystems with checksumming enabled. 1) We just disallow loading and directory inodes with EXT4_INDEX_FL when DIR_INDEX is not enabled. This is harsh but it should be very rare (it means someone disabled DIR_INDEX on existing filesystem and didn't run e2fsck), e2fsck can fix the problem, and we don't want to answer the difficult question: "Should we rather corrupt the directory more or should we ignore that DIR_INDEX feature is not set?" 2) When we find out htree structure is corrupted (but the filesystem and the directory should in support htrees), we continue just ignoring htree information for reading but we refuse to add new entries to the directory to avoid corrupting it more.

[PATCH] Revert "ARC: entry: fix potential EFA clobber when TIF_SYSCALL_TRACE"

by Vineet Gupta

This reverts commit 00fdec98d9881bf5173af09aebd353ab3b9ac729. (but only from 5.2 and prior kernels) The original commit was a preventive fix based on code-review and was auto-picked for stable back-port (for better or worse). It was OK for v5.3+ kernels, but turned up needing an implicit change 68e5c6f073bcf70 "(ARC: entry: EV_Trap expects r10 (vs. r9) to have exception cause)" merged in v5.3 which itself was not backported. So to summarize the stable backport of this patch for v5.2 and prior kernels is busted and it won't boot. The obvious solution is backport 68e5c6f073bcf70 but that is a pain as it doesn't revert cleanly and each of affected kernels (so far v4.19, v4.14, v4.9, v4.4) needs a slightly different massaged varaint. So the easier fix is to simply revert the backport from 5.2 and prior. The issue was not a big deal as it would cause strace to sporadically not work correctly. Waldemar Brodkorb first reported this when running ARC uClibc regressions on latest stable kernels (with offending backport). Once he bisected it, the analysis was trivial, so thx to him for this.

[PATCH 2/3] drm/i915: Break up error capture compression loops with cond_resched()

by Chris Wilson

As the error capture will compress user buffers as directed to by the user, it can take an arbitrary amount of time and space. Break up the compression loops with a call to cond_resched(), that will allow other processes to schedule (avoiding the soft lockups) and also serve as a warning should we try to make this loop atomic in the future.
