ovl: hash non-dir by lower inode for fsnotify

by Mark Salyzyn

(cherry pick from commit 764baba80168ad3adafb521d2ab483ccbc49e344) Commit 31747eda41ef ("ovl: hash directory inodes for fsnotify") fixed an issue of inotify watch on directory that stops getting events after dropping dentry caches. A similar issue exists for non-dir non-upper files, for example: $ mkdir -p lower upper work merged $ touch lower/foo $ mount -t overlay -o lowerdir=lower,workdir=work,upperdir=upper none merged $ inotifywait merged/foo & $ echo 2 > /proc/sys/vm/drop_caches $ cat merged/foo inotifywait doesn't get the OPEN event, because ovl_lookup() called from 'cat' allocates a new overlay inode and does not reuse the watched inode. Fix this by hashing non-dir overlay inodes by lower real inode in the following cases that were not hashed before this change: - A non-upper overlay mount - A lower non-hardlink when index=off A helper ovl_hash_bylower() was added to put all the logic and documentation about which real inode an overlay inode is hashed by into one place. The issue dates back to initial version of overlayfs, but this patch depends on ovl_inode code that was introduced in kernel v4.13.

[PATCH] keys: Fix the use of the C++ keyword "private" in uapi/linux/keyctl.h

by David Howells

The keyctl_dh_params struct in uapi/linux/keyctl.h contains the symbol "private" which means that the header file will cause compilation failure if #included in to a C++ program. Further, the patch that added the same struct to the keyutils package named the symbol "priv", not "private". The previous attempt to fix this (commit 8a2336e549d3) did so by simply renaming the kernel's copy of the field to dh_private, but this then breaks existing userspace and as such has been reverted (commit 8c0f9f5b309d). [And note, to those who think that wrapping the struct in extern "C" {} will work: it won't; that only changes how symbol names are presented to the assembler and linker.]. Instead, insert an anonymous union around the "private" member and add a second member in there with the name "priv" to match the one in the keyutils package. The "private" member is then wrapped in !__cplusplus cpp-conditionals to hide it from C++.

[PATCH] mmc: slot-gpio: Fix debounce time to use miliseconds again

The debounce value passed to mmc_gpiod_request_cd() function is in microseconds, but msecs_to_jiffies() requires the value to be in miliseconds to properly calculate the delay, so adjust the value stored in cd_debounce_delay_ms context entry.

[PATCH] platform-msi: Free descriptors in platform_msi_domain_free()

by Miquel Raynal

Since the addition of platform MSI support, there were two helpers supposed to allocate/free IRQs for a device: platform_msi_domain_alloc_irqs() platform_msi_domain_free_irqs() In these helpers, IRQ descriptors are allocated in the "alloc" routine while they are freed in the "free" one. Later, two other helpers have been added to handle IRQ domains on top of MSI domains: platform_msi_domain_alloc() platform_msi_domain_free() Seen from the outside, the logic is pretty close with the former helpers and people used it with the same logic as before: a platform_msi_domain_alloc() call should be balanced with a platform_msi_domain_free() call. While this is probably what was intended to do, the platform_msi_domain_free() does not remove/free the IRQ descriptor(s) created/inserted in platform_msi_domain_alloc(). One effect of such situation is that removing a module that requested an IRQ will let one orphaned IRQ descriptor (with an allocated MSI entry) in the device descriptors list. Next time the module will be inserted back, one will observe that the allocation will happen twice in the MSI domain, one time for the remaining descriptor, one time for the new one. It also has the side effect to quickly overshoot the maximum number of allocated MSI and then prevent any module requesting an interrupt in the same domain to be inserted anymore. This situation has been met with loops of insertion/removal of the mvpp2.ko module (requesting 15 MSIs each time).

Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. The Clear Linux container is building with NO_CLANG=1, the problem preventing its use when building for python3 has been identified and the next builds will build in ClearLinux with both gcc and clang.

[STABLE PATCH] slub: make ->cpu_partial unsigned int

by zhong jiang

From: Alexey Dobriyan <adobriyan(a)gmail.com> /* * cpu_partial determined the maximum number of objects * kept in the per cpu partial lists of a processor. */ Can't be negative. I hit a real issue that it will result in a large number of memory leak. Because Freeing slabs are in interrupt context. So it can trigger this issue. put_cpu_partial can be interrupted more than once. due to a union struct of lru and pobjects in struct page, when other core handles page->lru list, for eaxmple, remove_partial in freeing slab code flow, It will result in pobjects being a negative value(0xdead0000). Therefore, a large number of slabs will be added to per_cpu partial list. I had posted the issue to community before. The detailed issue description is as follows. Link: https://www.spinics.net/lists/kernel/msg2870979.html After applying the patch, The issue is fixed. So the patch is a effective bugfix. It should go into stable.
