c8c1095 | Linus Torvalds | 13 November 2021, 23:32:30 UTC | Merge tag 'zstd-for-linus-v5.16' of git://github.com/terrelln/linux Pull zstd update from Nick Terrell: "Update to zstd-1.4.10. Add myself as the maintainer of zstd and update the zstd version in the kernel, which is now 4 years out of date, to a much more recent zstd release. This includes bug fixes, much more extensive fuzzing, and performance improvements. And generates the kernel zstd automatically from upstream zstd, so it is easier to keep the zstd verison up to date, and we don't fall so far out of date again. This includes 5 commits that update the zstd library version: - Adds a new kernel-style wrapper around zstd. This wrapper API is functionally equivalent to the subset of the current zstd API that is currently used. The wrapper API changes to be kernel style so that the symbols don't collide with zstd's symbols. The update to zstd-1.4.10 maintains the same API and preserves the semantics, so that none of the callers need to be updated. All callers are updated in the commit, because there are zero functional changes. - Adds an indirection for `lib/decompress_unzstd.c` so it doesn't depend on the layout of `lib/zstd/` to include every source file. This allows the next patch to be automatically generated. - Imports the zstd-1.4.10 source code. This commit is automatically generated from upstream zstd (https://github.com/facebook/zstd). - Adds me (terrelln@fb.com) as the maintainer of `lib/zstd`. - Fixes a newly added build warning for clang. The discussion around this patchset has been pretty long, so I've included a FAQ-style summary of the history of the patchset, and why we are taking this approach. Why do we need to update? ------------------------- The zstd version in the kernel is based off of zstd-1.3.1, which is was released August 20, 2017. Since then zstd has seen many bug fixes and performance improvements. And, importantly, upstream zstd is continuously fuzzed by OSS-Fuzz, and bug fixes aren't backported to older versions. So the only way to sanely get these fixes is to keep up to date with upstream zstd. There are no known security issues that affect the kernel, but we need to be able to update in case there are. And while there are no known security issues, there are relevant bug fixes. For example the problem with large kernel decompression has been fixed upstream for over 2 years [1] Additionally the performance improvements for kernel use cases are significant. Measured for x86_64 on my Intel i9-9900k @ 3.6 GHz: - BtrFS zstd compression at levels 1 and 3 is 5% faster - BtrFS zstd decompression+read is 15% faster - SquashFS zstd decompression+read is 15% faster - F2FS zstd compression+write at level 3 is 8% faster - F2FS zstd decompression+read is 20% faster - ZRAM decompression+read is 30% faster - Kernel zstd decompression is 35% faster - Initramfs zstd decompression+build is 5% faster On top of this, there are significant performance improvements coming down the line in the next zstd release, and the new automated update patch generation will allow us to pull them easily. How is the update patch generated? ---------------------------------- The first two patches are preparation for updating the zstd version. Then the 3rd patch in the series imports upstream zstd into the kernel. This patch is automatically generated from upstream. A script makes the necessary changes and imports it into the kernel. The changes are: - Replace all libc dependencies with kernel replacements and rewrite includes. - Remove unncessary portability macros like: #if defined(_MSC_VER). - Use the kernel xxhash instead of bundling it. This automation gets tested every commit by upstream's continuous integration. When we cut a new zstd release, we will submit a patch to the kernel to update the zstd version in the kernel. The automated process makes it easy to keep the kernel version of zstd up to date. The current zstd in the kernel shares the guts of the code, but has a lot of API and minor changes to work in the kernel. This is because at the time upstream zstd was not ready to be used in the kernel envrionment as-is. But, since then upstream zstd has evolved to support being used in the kernel as-is. Why are we updating in one big patch? ------------------------------------- The 3rd patch in the series is very large. This is because it is restructuring the code, so it both deletes the existing zstd, and re-adds the new structure. Future updates will be directly proportional to the changes in upstream zstd since the last import. They will admittidly be large, as zstd is an actively developed project, and has hundreds of commits between every release. However, there is no other great alternative. One option ruled out is to replay every upstream zstd commit. This is not feasible for several reasons: - There are over 3500 upstream commits since the zstd version in the kernel. - The automation to automatically generate the kernel update was only added recently, so older commits cannot easily be imported. - Not every upstream zstd commit builds. - Only zstd releases are "supported", and individual commits may have bugs that were fixed before a release. Another option to reduce the patch size would be to first reorganize to the new file structure, and then apply the patch. However, the current kernel zstd is formatted with clang-format to be more "kernel-like". But, the new method imports zstd as-is, without additional formatting, to allow for closer correlation with upstream, and easier debugging. So the patch wouldn't be any smaller. It also doesn't make sense to import upstream zstd commit by commit going forward. Upstream zstd doesn't support production use cases running of the development branch. We have a lot of post-commit fuzzing that catches many bugs, so indiviudal commits may be buggy, but fixed before a release. So going forward, I intend to import every (important) zstd release into the Kernel. So, while it isn't ideal, updating in one big patch is the only patch I see forward. Who is responsible for this code? --------------------------------- I am. This patchset adds me as the maintainer for zstd. Previously, there was no tree for zstd patches. Because of that, there were several patches that either got ignored, or took a long time to merge, since it wasn't clear which tree should pick them up. I'm officially stepping up as maintainer, and setting up my tree as the path through which zstd patches get merged. I'll make sure that patches to the kernel zstd get ported upstream, so they aren't erased when the next version update happens. How is this code tested? ------------------------ I tested every caller of zstd on x86_64 (BtrFS, ZRAM, SquashFS, F2FS, Kernel, InitRAMFS). I also tested Kernel & InitRAMFS on i386 and aarch64. I checked both performance and correctness. Also, thanks to many people in the community who have tested these patches locally. Lastly, this code will bake in linux-next before being merged into v5.16. Why update to zstd-1.4.10 when zstd-1.5.0 has been released? ------------------------------------------------------------ This patchset has been outstanding since 2020, and zstd-1.4.10 was the latest release when it was created. Since the update patch is automatically generated from upstream, I could generate it from zstd-1.5.0. However, there were some large stack usage regressions in zstd-1.5.0, and are only fixed in the latest development branch. And the latest development branch contains some new code that needs to bake in the fuzzer before I would feel comfortable releasing to the kernel. Once this patchset has been merged, and we've released zstd-1.5.1, we can update the kernel to zstd-1.5.1, and exercise the update process. You may notice that zstd-1.4.10 doesn't exist upstream. This release is an artifical release based off of zstd-1.4.9, with some fixes for the kernel backported from the development branch. I will tag the zstd-1.4.10 release after this patchset is merged, so the Linux Kernel is running a known version of zstd that can be debugged upstream. Why was a wrapper API added? ---------------------------- The first versions of this patchset migrated the kernel to the upstream zstd API. It first added a shim API that supported the new upstream API with the old code, then updated callers to use the new shim API, then transitioned to the new code and deleted the shim API. However, Cristoph Hellwig suggested that we transition to a kernel style API, and hide zstd's upstream API behind that. This is because zstd's upstream API is supports many other use cases, and does not follow the kernel style guide, while the kernel API is focused on the kernel's use cases, and follows the kernel style guide. Where is the previous discussion? --------------------------------- Links for the discussions of the previous versions of the patch set below. The largest changes in the design of the patchset are driven by the discussions in v11, v5, and v1.

d0b51bf | Linus Torvalds | 13 November 2021, 20:03:03 UTC | Revert "mm: shmem: don't truncate page if memory failure happens" This reverts commit b9d02f1bdd98f38e6e5ecacc9786a8f58f3f8b2c. The error handling of that patch was fundamentally broken, and it needs to be entirely re-done. For example, in shmem_write_begin() it would call shmem_getpage(), then ignore the error return from that, and look at the page pointer contents instead. And in shmem_read_mapping_page_gfp(), the patch tested PageHWPoison() on a page pointer that two lines earlier had potentially been set as an error pointer.

The two patches in question add a new SCTP/LSM hook as well as an SELinux implementation of that LSM hook. The short version of "why?" is in the commit description of the revert patch, but I'll copy-n-paste the important bits below to save some time for the curious: ... Unfortunately these two patches were merged without proper review (the Reviewed-by and Tested-by tags from Richard Haines were for previous revisions of these patches that were significantly different) and there are outstanding objections from the SELinux maintainers regarding these patches. Work is currently ongoing to correct the problems identified in the reverted patches, as well as others that have come up during review, but it is unclear at this point in time when that work will be ready for inclusion in the mainline kernel. In the interest of not keeping objectionable code in the kernel for multiple weeks, and potentially a kernel release, we are reverting the two problematic patches. As usual with these things there is plenty of context to go with this and I'll try to do my best to provide that now. This effort started with a report of SCTP client side peel-offs not working correctly with SELinux, Ondrej Mosnacek put forth a patch which he believed properly addressed the problem but upon review by the netdev folks Xin Long described some additional issues and submitted an improved patchset for review. The SELinux folks reviewed Xin Long's initial patchset and suggested some changes which resulted in a second patchset (v2) from Xin Long; this is the patchset that is currently in your tree. Unfortunately this v2 patchset from Xin Long was merged before it had spent even just 24 hours on the mailing lists during the early days of the merge window, a time when many of us were busy doing verification of the newly released v5.15 kernel as well final review and testing of our v5.16 pull requests. Making matters worse, upon reviewing the v2 patchset there were both changes which were found objectionable by SELinux standards as well as additional outstanding SCTP/SELinux interaction problems. At this point we did two things: resumed working on a better fix for the SCTP/SELinux issue(s) - thank you Ondrej - and we asked the networking folks to revert the v2 patchset. The revert request was obviously rejected, but at the time I believed it was just going to be an issue for linux-next; I wasn't expecting something this significant that was merged into the networking tree during the merge window to make it into your tree in the same window, yet as of last night that is exactly what happened. While we continue to try and resolve the SCTP/SELinux problem I am asking once again to revert the v2 patches and not ship the current security_sctp_assoc_established() hook in a v5.16-rcX kernel. If I was confident that we could solve these issues in a week, maybe two, I would refrain from asking for the revert but our current estimate is for a minimum of two weeks for the next patch revision. With the likelihood of additional delays due to normal patch review follow-up and/or holidays it seems to me that the safest course of action is to revert the patch both to try and keep some objectionable code out of a release kernel and limit the chances of any new breakages from such a change. While the SCTP/SELinux code in v5.15 and earlier has problems, they are known problems, and I'd like to try and avoid creating new and different problems while we work to fix things properly. One final thing to mention: Xin Long's v2 patchset consisted of four patches, yet this revert is for only the last two. We see the first two patches as good, reasonable, and not likely to cause an issue. In an attempt to create a cleaner revert patch we suggest leaving the first two patches in the tree as they are currently" * tag 'selinux-pr-20211112' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: net,lsm,selinux: revert the security_sctp_assoc_established() hook | 13 November 2021, 18:27:50 UTC |

Also the DEFINE_SUITE(vectors_page) should be done where its function is implemented, in tools/perf/arch/arm/tests/vectors-page.c, so that we can make it static, as we don't have anymore its declaration in tests.h.

This lock should be taken whenever dealing with the channel fields, and should be held only for very short intervals which will not sleep. Currently, all channel related fields in cifs_ses structure are protected by session_mutex. However, this mutex is held for long periods (sometimes while waiting for a reply from server).

The copy_from_user code will already handles that case if the address is going to fault. Looking futher I realized that if we care about not allowing struct vm86plus_struct at address 0 it should be do_sys_vm86 (the system call) that does the filtering. Not way down deep when the emulation has completed in save_v86_state. So let's just remove the silly case of attempting to filter a userspace address with a BUG_ON. Existing userspace can't break and it won't make the kernel any more attackable as the userspace access helpers will handle it, if it isn't a good userspace pointer. I have run the reproducer the fuzzer gave me before I made this change and it reproduced, and after I made this change and I have not seen the reported failure. So it does looks like this fixes the reported issue.

The histogram treats char array as a string and there are 2 types of char array in the event, fixed-size and dynamic string. The dynamic string (__data_loc) field must be null terminated, but the fixed-size char array field may not be null terminated (not a string, but just a data). In that case, histogram can copy the data after the field. This uses the original field size for fixed-size char array field to restrict the histogram not to access over the original field size.
