2023-02-23ipv6: Add lwtunnel encap size of all siblings in nexthop calculationLu Wei
In function rt6_nlmsg_size(), the length of nexthop is calculated by multipling the nexthop length of fib6_info and the number of siblings. However if the fib6_info has no lwtunnel but the siblings have lwtunnels, the nexthop length is less than it should be, and it will trigger a warning in inet6_rt_notify() as follows: WARNING: CPU: 0 PID: 6082 at net/ipv6/route.c:6180 inet6_rt_notify+0x120/0x130 ......

There have been some recently reported ORC unwinder warnings like: WARNING: can't access registers at entry_SYSCALL_64_after_hwframe+0x63/0xcd WARNING: stack going in the wrong direction? at __sys_setsockopt+0x2c6/0x5b0 net/socket.c:2271 And a KASAN warning: BUG: KASAN: stack-out-of-bounds in unwind_next_frame (arch/x86/include/asm/ptrace.h:136 arch/x86/kernel/unwind_orc.c:455) It turns out the 'signal' bit isn't getting propagated from the unwind hints to the ORC entries, making the unwinder confused at times.

2023-02-23drm/i915/gvt: Avoid full proxy f_ops for debugfs attributesDeepak R Varma
Using DEFINE_SIMPLE_ATTRIBUTE macro with the debugfs_create_file() function adds the overhead of introducing a proxy file operation functions to wrap the original read/write inside file removal protection functions. This adds significant overhead in terms of introducing and managing the proxy factory file operations structure and function wrapping at runtime. As a replacement, a combination of DEFINE_DEBUGFS_ATTRIBUTE macro paired with debugfs_create_file_unsafe() is suggested to be used instead. The DEFINE_DEBUGFS_ATTRIBUTE utilises debugfs_file_get() and debugfs_file_put() wrappers to protect the original read and write function calls for the debug attributes. There is no need for any runtime proxy file operations to be managed by the debugfs core.

2023-02-22ptp: vclock: use mutex to fix "sleep on atomic" bugÍñigo Huguet
vclocks were using spinlocks to protect access to its timecounter and cyclecounter. Access to timecounter/cyclecounter is backed by the same driver callbacks that are used for non-virtual PHCs, but the usage of the spinlock imposes a new limitation that didn't exist previously: now they're called in atomic context so they mustn't sleep. Some drivers like sfc or ice may sleep on these callbacks, causing errors like "BUG: scheduling while atomic: ptp5/25223/0x00000002" Fix it replacing the vclock's spinlock by a mutex. It fix the mentioned bug and it doesn't introduce longer delays. I've tested synchronizing various different combinations of clocks: - vclock->sysclock - sysclock->vclock - vclock->vclock - hardware PHC in different NIC -> vclock - created 4 vclocks and launch 4 parallel phc2sys processes with lockdep enabled In all cases, comparing the delays reported by phc2sys, they are in the same range of values than before applying the patch.

In loop_set_status_from_info(), lo->lo_offset and lo->lo_sizelimit should be checked before reassignment, because if an overflow error occurs, the original correct value will be changed to the wrong value, and it will not be changed back. More, the original patch did not solve the problem, the value was set and ioctl returned an error, but the subsequent io used the value in the loop driver, which still caused an alarm: loop_handle_cmd do_req_filebacked loff_t pos = ((loff_t) blk_rq_pos(rq) << 9) + lo->lo_offset; lo_rw_aio cmd->iocb.ki_pos = pos Fixes: c490a0b5a4f3 ("loop: Check for overflow while configuring loop") Signed-off-by: Zhong Jinghua <zhongjinghua@huawei.com> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Link: https://lore.kernel.org/r/20230221095027.3656193-1-zhongjinghua@huaweicloud.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

KVEC). With these changes, cifs will apply the appropriate cleanup. - Making it easier to transition to using folios in cifs rather than pages by dealing with them through BVEC and XARRAY iterators. - Allowing cifs to use the new splice function The remainder are: - fixes for stable, including various fixes for uninitialized memory, wrong length field causing mount issue to very old servers, important directory lease fixes and reconnect fixes - cleanups (unused code removal, change one element array usage, and a change form strtobool to kstrtobool, and Kconfig cleanups) - SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes - reconnect fixes - multichannel fixes, including improving channel allocation (to least used channel) - remove the last use of lock_page_killable by moving to folio_lock_killable" * tag '6.3-rc-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6: (46 commits) update internal module version number for cifs.ko cifs: update ip_addr for ses only for primary chan setup cifs: use tcon allocation functions even for dummy tcon cifs: use the least loaded channel for sending requests cifs: DIO to/from KVEC-type iterators should now work cifs: Remove unused code cifs: Build the RDMA SGE list directly from an iterator cifs: Change the I/O paths to use an iterator rather than a page list cifs: Add a function to read into an iter from a socket cifs: Add some helper functions cifs: Add a function to Hash the contents of an iterator cifs: Add a function to build an RDMA SGE list from an iterator netfs: Add a function to extract an iterator into a scatterlist netfs: Add a function to extract a UBUF or IOVEC into a BVEC iterator cifs: Implement splice_read to pass down ITER_BVEC not ITER_PIPE splice: Export filemap/direct_splice_read() iov_iter: Add a function to extract a page list from an iterator iov_iter: Define flags to qualify page extraction. splice: Add a func to do a splice from an O_DIRECT file without ITER_PIPE splice: Add a func to do a splice from a buffered file without ITER_PIPE ...

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom Pull Qualcomm clk driver updates from Bjorn Andersson: Support for requesting the next power_off operation for a genpd to be synchronous is introduced, and implemented in the GDSC driver. To allow the GPU driver to request power_off to wait for the GDSC to actually collapse. Support for QDU1000/QRU1000 Global clock controller, SA8775P Global clock controller, SM8550 TCSR and display clock controller, SM6350 clock controller, nd MSM8996 CBF and APCS clock controllers is introduced. Parent references are updated across a large number of clock drivers, to align with the design changes since those drivers where introduced. Similarly, test clocks has been dropped from a range of drivers. A range of fixes for the MSM8996 CPU clock controller is introduced. MSM8974 GCC is transitioned off the externally defined sleep_clk. GDSC in the global clock controller for QCS404 is added, and various parent definitions are cleaned up. The SDCC core clocks on SM6115 are moved for floor_ops. Programming of clk_dis_wait for GPU CX GDSC on SC7180 and SDM845 are moved to use the recently introduced properties in the GDSC struct. The RPMh clock driver gains SM8550 and SA8775P clocks, and the IPA clock is added on a variety of platforms. The SMD RPM driver receives a big cleanup, in particular a move away from duplicating declaration of identical clocks between multiple platforms. A few missing clocks across msm8998, msm8992, msm8916, qcs404 are added as well. Using devm_pm_runtime_enable() to clean up some duplication is done across SM8250 display and video clock controllers, SM8450 display clock controller and SC7280 LPASS clock controller. Devicetree binding changes for above mentioned additions and changes are introduced. Support for postponing clk_disable_unused() until sync_state was introduced, but later reverted again, awaiting an agreement on the solution. Lastly, a change to pad a few registers in the SM8250 DTS to 8 digits was picked up in the wrong tree and kept here, to avoid rebasing. * tag 'qcom-clk-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (142 commits) clk: qcom: Revert sync_state based clk_disable_unused dt-bindings: clock: Merge qcom,gpucc-sm8350 into qcom,gpucc.yaml clk: qcom: gpucc-sdm845: fix clk_dis_wait being programmed for CX GDSC clk: qcom: gpucc-sc7180: fix clk_dis_wait being programmed for CX GDSC dt-bindings: clock: qcom,sa8775p-gcc: add the power-domains property clk: qcom: cpu-8996: add missing cputype include clk: qcom: gcc-sa8775p: remove unused variables clk: qcom: smd-rpm: provide RPM_SMD_XO_CLK_SRC on MSM8996 platform clk: qcom: add msm8996 Core Bus Framework (CBF) support dt-bindings: clock: qcom,msm8996-cbf: Describe the MSM8996 CBF clock controller clk: qcom: add the driver for the MSM8996 APCS clocks clk: qcom: gcc-qcs404: fix duplicate initializer warning clk: qcom: cpu-8996: change setup sequence to follow vendor kernel clk: qcom: cpu-8996: fix PLL clock ops clk: qcom: cpu-8996: fix ACD initialization clk: qcom: cpu-8996: fix PLL configuration sequence clk: qcom: cpu-8996: move qcom_cpu_clk_msm8996_acd_init call clk: qcom: cpu-8996: setup PLLs before registering clocks clk: qcom: cpu-8996: simplify the cpu_clk_notifier_cb clk: qcom: cpu-8996: skip ACD init if the setup is valid ...

This provides a clean path for deprecating and removing insecure encryption types based on DES and SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with Kerberos may now be used on systems with fips enabled. In addition to these, NFSD is now able to handle crossing into an auto-mounted mount point on an exported NFS mount. A number of fixes have been made to NFSD's server-side copy implementation.

2023-02-22rtc: efi: Avoid spamming the log on RTC read failureArd Biesheuvel
There are cases where the EFI runtime services may end up in a funny state, e.g., due to a crash in the variable services, and this affects other EFI runtime services as well. That means that, even though GetTime() should not return an error, there are cases where it might, and there is no point in logging such an occurrence multiple times. This works around an issue where user space -apparently- keeps hitting on /dev/rtc if it fails to read the h/w clock, resulting in a tsunami of log spam and a non-responsive system as a result.
