[PATCH stable 4.9] arm64: kpti: Whitelist Cortex-A CPUs that don't implement the CSV3 field

by Florian Fainelli

From: Will Deacon <will.deacon(a)arm.com> commit 2a355ec25729053bb9a1a89b6c1d1cdd6c3b3fb1 upstream. While the CSV3 field of the ID_AA64_PFR0 CPU ID register can be checked to see if a CPU is susceptible to Meltdown and therefore requires kpti to be enabled, existing CPUs do not implement this field. We therefore whitelist all unaffected Cortex-A CPUs that do not implement the CSV3 field.

[PATCH stable 4.19] crypto: geode-aes - switch to skcipher for cbc(aes) fallback

by Florian Bezdeka

commit 504582e8e40b90b8f8c58783e2d1e4f6a2b71a3a upstream. [Why] This is the backport of the upstream commit for the 4.19 stable tree. [How] Just replaced all occurrences of *sync_skcipher* with *skcipher* (including upper case ones), and passing 'CRYPTO_ALG_ASYNC | CRYPTO_ALG_NEED_FALLBACK' as the third parameter to crypto_alloc_skcipher. Commit 79c65d179a40e145 ("crypto: cbc - Convert to skcipher") updated the generic CBC template wrapper from a blkcipher to a skcipher algo, to get away from the deprecated blkcipher interface. However, as a side effect, drivers that instantiate CBC transforms using the blkcipher as a fallback no longer work, since skciphers can wrap blkciphers but not the other way around. This broke the geode-aes driver. So let's fix it by moving to the sync skcipher interface when allocating the fallback. At the same time, align with the generic API for ECB and CBC by rejecting inputs that are not a multiple of the AES block size.

[PATCH] sd: Fix REQ_OP_ZONE_REPORT completion handling

by Masato Suzuki

ZBC/ZAC report zones command may return less bytes than requested if the number of matching zones for the report request is small. However, unlike read or write commands, the remainder of incomplete report zones commands cannot be automatically requested by the block layer: the start sector of the next report cannot be known, and the report reply may not be 512B aligned for SAS drives (a report zone reply size is always a multiple of 64B). The regular request completion code executing bio_advance() and restart of the command remainder part currently causes invalid zone descriptor data to be reported to the caller if the report zone size is smaller than 512B (a case that can happen easily for a report of the last zones of a SAS drive for example). Since blkdev_report_zones() handles report zone command processing in a loop until completion (no more zones are being reported), we can safely avoid that the block layer performs an incorrect bio_advance() call and restart of the remainder of incomplete report zone BIOs. To do so, always indicate a full completion of REQ_OP_ZONE_REPORT by setting good_bytes to the request buffer size and by setting the command resid to 0. This does not affect the post processing of the report zone reply done by sd_zbc_complete() since the reply header indicates the number of zones reported.

FAILED: patch "[PATCH] tracing: Fix histogram code when expression has same var as" failed to apply to 4.19-stable tree

The patch below does not apply to the 4.19-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 8bcebc77e85f3d7536f96845a0fe94b1dddb6af0 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> Date: Mon, 20 Jan 2020 13:07:31 -0500 Subject: [PATCH] tracing: Fix histogram code when expression has same var as value While working on a tool to convert SQL syntex into the histogram language of the kernel, I discovered the following bug: # echo 'first u64 start_time u64 end_time pid_t pid u64 delta' >> synthetic_events # echo 'hist:keys=pid:start=common_timestamp' > events/sched/sched_waking/trigger # echo 'hist:keys=next_pid:delta=common_timestamp-$start,start2=$start:onmatch(sched.sched_waking).trace(first,$start2,common_timestamp,next_pid,$delta)' > events/sched/sched_switch/trigger Would not display any histograms in the sched_switch histogram side. But if I were to swap the location of "delta=common_timestamp-$start" with "start2=$start" Such that the last line had: # echo 'hist:keys=next_pid:start2=$start,delta=common_timestamp-$start:onmatch(sched.sched_waking).trace(first,$start2,common_timestamp,next_pid,$delta)' > events/sched/sched_switch/trigger The histogram works as expected. What I found out is that the expressions clear out the value once it is resolved. As the variables are resolved in the order listed, when processing: delta=common_timestamp-$start The $start is cleared. When it gets to "start2=$start", it errors out with "unresolved symbol" (which is silent as this happens at the location of the trace), and the histogram is dropped. When processing the histogram for variable references, instead of adding a new reference for a variable used twice, use the same reference. That way, not only is it more efficient, but the order will no longer matter in processing of the variables. >From Tom Zanussi: "Just to clarify some more about what the problem was is that without your patch, we would have two separate references to the same variable, and during resolve_var_refs(), they'd both want to be resolved separately, so in this case, since the first reference to start wasn't part of an expression, it wouldn't get the read-once flag set, so would be read normally, and then the second reference would do the read-once read and also be read but using read-once. So everything worked and you didn't see a problem: from: start2=$start,delta=common_timestamp-$start In the second case, when you switched them around, the first reference would be resolved by doing the read-once, and following that the second reference would try to resolve and see that the variable had already been read, so failed as unset, which caused it to short-circuit out and not do the trigger action to generate the synthetic event: to: delta=common_timestamp-$start,start2=$start With your patch, we only have the single resolution which happens correctly the one time it's resolved, so this can't happen."

[v4 PATCH] mm: move_pages: report the number of non-attempted pages

by Yang Shi

Since commit a49bd4d71637 ("mm, numa: rework do_pages_move"), the semantic of move_pages() has changed to return the number of non-migrated pages if they were result of a non-fatal reasons (usually a busy page). This was an unintentional change that hasn't been noticed except for LTP tests which checked for the documented behavior. There are two ways to go around this change. We can even get back to the original behavior and return -EAGAIN whenever migrate_pages is not able to migrate pages due to non-fatal reasons. Another option would be to simply continue with the changed semantic and extend move_pages documentation to clarify that -errno is returned on an invalid input or when migration simply cannot succeed (e.g. -ENOMEM, -EBUSY) or the number of pages that couldn't have been migrated due to ephemeral reasons (e.g. page is pinned or locked for other reasons). This patch implements the second option because this behavior is in place for some time without anybody complaining and possibly new users depending on it. Also it allows to have a slightly easier error handling as the caller knows that it is worth to retry when err > 0. But since the new semantic would be aborted immediately if migration is failed due to ephemeral reasons, need include the number of non-attempted pages in the return value too.

From: Suren Baghdasaryan <surenb(a)google.com> When ashmem file is being mmapped the resulting vma->vm_file points to the backing shmem file with the generic fops that do not check ashmem permissions like fops of ashmem do. Fix that by disallowing mapping operation for backing shmem file.
