95e7a45 Vlastimil Babka 13 January 2023, 17:33:45 UTC Revert "mm/compaction: fix set skip in fast_find_migrateblock" This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c. We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged stalling CPU for long periods of time. Investigation of tracepoint data shows that compaction is stuck in repeating fast_find_migrateblock() based migrate page isolation, and then fails to migrate all isolated pages. Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock") was suspected as it was merged in 6.1 and in theory can indeed remove a termination condition for fast_find_migrateblock() under certain conditions, as it removes a place that always marks a scanned pageblock from being re-scanned. There are other such places, but those can be skipped under certain conditions, which seems to match the tracepoint data. Testing of revert also appears to have resolved the issue, thus revert the commit until a more robust solution for the original problem is developed. It's also likely this will fix qemu stalls with 6.1 kernel reported in Link 2, but that is not yet confirmed.

4f11ada Miklos Szeredi 24 January 2023, 15:41:18 UTC ovl: fail on invalid uid/gid mapping at copy up If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then copy-up should fail, just like it would fail if the mounter task was doing the copy using "cp -a". There's a corner case where the "cp -a" would succeed but copy up fail: if there's a mapping of the invalid uid/gid (65534 by default) in the user namespace. This is because stat(2) will return this value if the mapping doesn't exist in the current user_ns and "cp -a" will in turn be able to create a file with this uid/gid. This behavior would be inconsistent with POSIX ACL's, which return -1 for invalid uid/gid which result in a failed copy. For consistency and simplicity fail the copy of the st_uid/st_gid are invalid.

ef5c600 Dylan Yudaken 27 January 2023, 10:59:11 UTC io_uring: always prep_async for drain requests Drain requests all go through io_drain_req, which has a quick exit in case there is nothing pending (ie the drain is not useful). In that case it can run the issue the request immediately. However for safety it queues it through task work. The problem is that in this case the request is run asynchronously, but the async work has not been prepared through io_req_prep_async. This has not been a problem up to now, as the task work always would run before returning to userspace, and so the user would not have a chance to race with it. However - with IORING_SETUP_DEFER_TASKRUN - this is no longer the case and the work might be defered, giving userspace a chance to change data being referred to in the request. Instead _always_ prep_async for drain requests, which is simpler anyway and removes this issue.

677d85e Ivo Borisov Shopov 26 January 2023, 13:10:33 UTC tools: gpio: fix -c option of gpio-event-mon Following line should listen for a rising edge and exit after the first one since '-c 1' is provided. # gpio-event-mon -n gpiochip1 -o 0 -r -c 1 It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the above command doesn't exit after the first rising edge it keep listening for an event forever. The '-c 1' is not taken into an account. The problem is in commit 62757c32d5db ("tools: gpio: add multi-line monitoring to gpio-event-mon"). Before this commit the iterator 'i' in monitor_device() is used for counting of the events (loops). In the case of the above command (-c 1) we should start from 0 and increment 'i' only ones and hit the 'break' statement and exit the process. But after the above commit counting doesn't start from 0, it start from 1 when we listen on one line. It is because 'i' is used from one more purpose, counting of lines (num_lines) and it isn't restore to 0 after following code for (i = 0; i < num_lines; i++) gpiotools_set_bit(&values.mask, i); Restore the initial value of the iterator to 0 in order to allow counting of loops to work for any cases.

a428eb4 Robin Murphy 23 January 2023, 18:30:38 UTC Partially revert "perf/arm-cmn: Optimise DTC counter accesses" It turns out the optimisation implemented by commit 4f2c3872dde5 is totally broken, since all the places that consume hw->dtcs_used for events other than cycle count are still not expecting it to be sparsely populated, and fail to read all the relevant DTC counters correctly if so. If implemented correctly, the optimisation potentially saves up to 3 register reads per event update, which is reasonably significant for events targeting a single node, but still not worth a massive amount of additional code complexity overall. Getting it right within the current design looks a fair bit more involved than it was ever intended to be, so let's just make a functional revert which restores the old behaviour while still backporting easily.

1939882 Dan Williams 21 January 2023, 00:26:12 UTC cxl/pmem: Fix nvdimm unregistration when cxl_pmem driver is absent The cxl_pmem.ko module houses the driver for both cxl_nvdimm_bridge objects and cxl_nvdimm objects. When the core creates a cxl_nvdimm it arranges for it to be autoremoved when the bridge goes down. However, if the bridge never initialized because the cxl_pmem.ko module never loaded, it sets up a the following crash scenario: BUG: kernel NULL pointer dereference, address: 0000000000000478 [..] RIP: 0010:cxl_nvdimm_probe+0x99/0x140 [cxl_pmem] [..] Call Trace: <TASK> cxl_bus_probe+0x17/0x50 [cxl_core] really_probe+0xde/0x380 __driver_probe_device+0x78/0x170 driver_probe_device+0x1f/0x90 __driver_attach+0xd2/0x1c0 bus_for_each_dev+0x79/0xc0 bus_add_driver+0x1b1/0x200 driver_register+0x89/0xe0 cxl_pmem_init+0x50/0xff0 [cxl_pmem] It turns out the recent rework to simplify nvdimm probing obviated the need to unregister cxl_nvdimm objects at cxl_nvdimm_bridge ->remove() time. Leave the cxl_nvdimm device registered until the hosting cxl_memdev departs. The alternative is that the cxl_memdev needs to be reattached whenever the cxl_nvdimm_bridge attach state cycles, which is awkward and unnecessary. The only requirement is to make sure that when the cxl_nvdimm_bridge goes away any dependent cxl_nvdimm objects are shutdown. Handle that in unregister_nvdimm_bus(). With these registration entanglements removed there is no longer a need to pre-load the cxl_pmem module in cxl_acpi.

When we service a long HPD, we still need to run dm_helpers_dp_mst_write_payload_allocation_table() to update drm mst_mgr's relevant variable.

1119e1f Lyude Paul 23 November 2022, 19:50:16 UTC drm/amdgpu/display/mst: Fix mst_state->pbn_div and slot count assignments Looks like I made a pretty big mistake here without noticing: it seems when I moved the assignments of mst_state->pbn_div I completely missed the fact that the reason for us calling drm_dp_mst_update_slots() earlier was to account for the fact that we need to call this function using info from the root MST connector, instead of just trying to do this from each MST encoder's atomic check function. Otherwise, we end up filling out all of DC's link information with zeroes. So, let's restore that and hopefully fix this DSC regression.

As a result daemons without FUSE_POSIX_ACL are unable to use posix acls like they used to. Fix this by copying what we did for overlayfs during the posix acl api conversion. Make fuse implement a dedicated ->get_inode_acl() method as does overlayfs. Fuse can then also uses this to express different needs for vfs permission checking during lookup and acl based retrieval via the regular system call path. This allows fuse to continue to refuse retrieving posix acls for daemons that don't set FUSE_POSXI_ACL for permission checking while also allowing a fuse server to retrieve it via the usual system calls" * tag 'fs.fuse.acl.v6.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping: fuse: fixes after adapting to new posix acl api 25 January 2023, 17:15:15 UTC

c1d6105 Ley Foon Tan 05 January 2023, 03:37:05 UTC riscv: Move call to init_cpu_topology() to later initialization stage If "capacity-dmips-mhz" is present in a CPU DT node, topology_parse_cpu_capacity() will fail to allocate memory. arm64, with which this code path is shared, does not call topology_parse_cpu_capacity() until later in boot where memory allocation is available. While "capacity-dmips-mhz" is not yet a valid property on RISC-V, invalid properties should be ignored rather than cause issues. Move init_cpu_topology(), which calls topology_parse_cpu_capacity(), to a later initialization stage, to match arm64. As a side effect of this change, RISC-V is "protected" from changes to core topology code that would work on arm64 where memory allocation is safe but on RISC-V isn't.

This commit fixes it so that on Intel platforms it knows the functional mode is always MMC. I also fixed a potential problem that a platform may try to set the mode for both MMC and PSC - which was incorrect. Tested on X1 Carbon 9 (Intel) and Z13 (AMD).

Next patch in this series provides a more simple approach to multihoming support. 4) Unify HEARTBEAT_ACKED and ESTABLISHED states for SCTP multihoming support, use default ESTABLISHED of 210 seconds based on heartbeat timeout * maximum number of retransmission + round-trip timeout. Otherwise, SCTP conntrack entry that represents secondary paths remain stale in the table for up to 5 days.

This was fine, but created a corner case issue in the case of ice_register_netdev() failing. In that case, the driver would end up calling ice_devlink_destroy_pf_port() twice. Additionally, it makes no sense to tie creation of the devlink PF port to the creation of the netdev so separate out the code to create/destroy the devlink PF port from the netdev code. This makes it a cleaner interface.

458e279 Marcelo Ricardo Leitner 23 January 2023, 17:59:33 UTC sctp: fail if no bound addresses can be used for a given scope Currently, if you bind the socket to something like: servaddr.sin6_family = AF_INET6; servaddr.sin6_port = htons(0); servaddr.sin6_scope_id = 0; inet_pton(AF_INET6, "::1", &servaddr.sin6_addr); And then request a connect to: connaddr.sin6_family = AF_INET6; connaddr.sin6_port = htons(20000); connaddr.sin6_scope_id = if_nametoindex("lo"); inet_pton(AF_INET6, "fe88::1", &connaddr.sin6_addr); What the stack does is: - bind the socket - create a new asoc - to handle the connect - copy the addresses that can be used for the given scope - try to connect But the copy returns 0 addresses, and the effect is that it ends up trying to connect as if the socket wasn't bound, which is not the desired behavior. This unexpected behavior also allows KASLR leaks through SCTP diag interface. The fix here then is, if when trying to copy the addresses that can be used for the scope used in connect() it returns 0 addresses, bail out. This is what TCP does with a similar reproducer.

0254127 Petr Pavlu 05 December 2022, 10:35:57 UTC module: Don't wait for GOING modules During a system boot, it can happen that the kernel receives a burst of requests to insert the same module but loading it eventually fails during its init call. For instance, udev can make a request to insert a frequency module for each individual CPU when another frequency module is already loaded which causes the init function of the new module to return an error. Since commit 6e6de3dee51a ("kernel/module.c: Only return -EEXIST for modules that have finished loading"), the kernel waits for modules in MODULE_STATE_GOING state to finish unloading before making another attempt to load the same module. This creates unnecessary work in the described scenario and delays the boot. In the worst case, it can prevent udev from loading drivers for other devices and might cause timeouts of services waiting on them and subsequently a failed boot. This patch attempts a different solution for the problem 6e6de3dee51a was trying to solve. Rather than waiting for the unloading to complete, it returns a different error code (-EBUSY) for modules in the GOING state. This should avoid the error situation that was described in 6e6de3dee51a (user space attempting to load a dependent module because the -EEXIST error code would suggest to user space that the first module had been loaded successfully), while avoiding the delay situation too. This has been tested on linux-next since December 2022 and passes all kmod selftests except test 0009 with module compression enabled but it has been confirmed that this issue has existed and has gone unnoticed since prior to this commit and can also be reproduced without module compression with a simple usleep(5000000) on tools/modprobe.c [0]. These failures are caused by hitting the kernel mod_concurrent_max and can happen either due to a self inflicted kernel module auto-loead DoS somehow or on a system with large CPU count and each CPU count incorrectly triggering many module auto-loads. Both of those issues need to be fixed in-kernel.

854f091 Linus Torvalds 24 January 2023, 17:23:56 UTC ext4: make xattr char unsignedness in hash explicit Commit f3bbac32475b ("ext4: deal with legacy signed xattr name hash values") added a hashing function for the legacy case of having the xattr hash calculated using a signed 'char' type. It left the unsigned case alone, since it's all implicitly handled by the '-funsigned-char' compiler option. However, there's been some noise about back-porting it all into stable kernels that lack the '-funsigned-char', so let's just make that at least possible by making the whole 'this uses unsigned char' very explicit in the code itself. Whether such a back-port is really warranted or not, I'll leave to others, but at least together with this change it is technically sensible. Also, add a 'pr_warn_once()' for reporting the "hey, signedness for this hash calculation has changed" issue. Hopefully it never triggers except for that xfstests generic/454 test-case, but even if it does it's just good information to have. If for no other reason than "we can remove the legacy signed hash code entirely if nobody ever sees the message any more".
