2023-03-24net: phy: dp83869: fix default value for tx-/rx-internal-delayJosua Mayer
dp83869 internally uses a look-up table for mapping supported delays in nanoseconds to register values. When specific delays are defined in device-tree, phy_get_internal_delay does the lookup automatically returning an index. The default case wrongly assigns the nanoseconds value from the lookup table, resulting in numeric value 2000 applied to delay configuration register, rather than the expected index values 0-7 (7 for 2000). Ultimately this issue broke RX for 1Gbps links. Fix default delay configuration by assigning the intended index value directly.

2023-03-24sfc: ef10: don't overwrite offload features at NIC resetÍñigo Huguet
At NIC reset, some offload features related to encapsulated traffic might have changed (this mainly happens if the firmware-variant is changed with the sfboot userspace tool). Because of this, features are checked and set again at reset time. However, this was not done right, and some features were improperly overwritten at NIC reset: - Tunneled IPv6 segmentation was always disabled - Features disabled with ethtool were reenabled - Features that becomes unsupported after the reset were not disabled Also, checking if the device supports IPV6_CSUM to enable TSO6 is no longer necessary because all currently supported devices support it. Additionally, move the assignment of some other features to the EF10_OFFLOAD_FEATURES macro, like it is done in ef100, leaving the selection of features in efx_pci_probe_post_io a bit cleaner.

2023-03-24smb3: fix unusable share after force unmount failureSteve French
If user does forced unmount ("umount -f") while files are still open on the share (as was seen in a Kubernetes example running on SMB3.1.1 mount) then we were marking the share as "TID_EXITING" in umount_begin() which caused all subsequent operations (except write) to fail ... but unfortunately when umount_begin() is called we do not know yet that there are open files or active references on the share that would prevent unmount from succeeding. Kubernetes had example when they were doing umount -f when files were open which caused the share to become unusable until the files were closed (and the umount retried). Fix this so that TID_EXITING is not set until we are about to send the tree disconnect (not at the beginning of forced umounts in umount_begin) so that if "umount -f" fails (due to open files or references) the mount is still usable.

Get rid of any prefix paths in @path before lookup_positive_unlocked() as it will call ->lookup() which already adds those prefix paths through build_path_from_dentry(). This has caused a performance regression when mounting shares with a prefix path where readdir(2) would end up retrying several times to open bad directory names that contained duplicate prefix paths.

Modern versions of FVP_Base_RevC-2xAEMvA contain a Virtio RNG device, use of which can dramatically speed up the time taken for Linux to initialize its CRNG, from 10s of seconds in some cases, to instant. This improves the debug cycle significantly. However, there are 2 barriers to getting people to use it. The first is that the defconfig doesn't have the required driver. The second is that the device is disabled in the device tree (for back-compat since older versions of the FVP don't have the device). Here we solve the first issue.

2023-03-24tools/memory-model: Remove out-of-date SRCU documentationAndrea Parri
Commit 6cd244c87428 ("tools/memory-model: Provide exact SRCU semantics") changed the semantics of partially overlapping SRCU read-side critical sections (among other things), making such documentation out-of-date. The new, semantic changes are discussed in explanation.txt. Remove the out-of-date documentation.

The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/memory-model` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Reviewed-by: Akira Yokosawa <akiyks@gmail.com> Signed-off-by: Paul E.

2023-03-24tools/memory-model: Use "-unroll 0" to keep --hw runs finitePaul E. McKenney
Litmus tests involving atomic operations produce LL/SC loops on a number of architectures, and unrolling these loops can result in excessive verification times or even stack overflows. This commit therefore uses the "-unroll 0" herd7 argument to avoid unrolling, on the grounds that additional passes through an LL/SC loop should not change the verification. Note however, that certain bugs in the mapping of the LL/SC loop to machine instructions may go undetected. On the other hand, herd7 might not be the best vehicle for finding such bugs in any case. (You do stress-test your architecture-specific code, don't you?) Suggested-by: Luc Maranget <luc.maranget@inria.fr> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Make judgelitmus.sh handle scripted Result: tagPaul E. McKenney
The scripts that generate the litmus tests in the "auto" directory of the https://github.com/paulmckrcu/litmus archive place the "Result:" tag into a single-line ocaml comment, which judgelitmus.sh currently does not recognize. This commit therefore makes judgelitmus.sh recognize both the multiline comment format that it currently does and the automatically generated single-line format. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Add data-race capabilities to judgelitmus.shPaul E. McKenney
This commit adds functionality to judgelitmus.sh to allow it to handle both the "DATARACE" markers in the "Result:" comments in litmus tests and the "Flag data-race" markers in LKMM output. For C-language tests, if either marker is present, the other must also be as well, at least for litmus tests having a "Result:" comment. If the LKMM output indicates a data race, then failures of the Always/Sometimes/Never portion of the "Result:" prediction are forgiven. The reason for forgiving "Result:" mispredictions is that data races can result in "interesting" compiler optimizations, so that all bets are off in the data-race case.

2023-03-24tools/memory-model: Add "--" to parseargs.sh for additional argumentsPaul E. McKenney
Currently, parseargs.sh expects to consume all the command-line arguments, which prevents the calling script from having any of its own arguments. This commit therefore causes parseargs.sh to stop consuming arguments when it encounters a "--" argument, leaving any remaining arguments for the calling script. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Make history-check scripts use mselect7Paul E. McKenney
The history-check scripts currently use grep to ignore non-C-language litmus tests, which is a bit fragile. This commit therefore enlists the aid of "mselect7 -arch C", given Luc Maraget's recent modifications that allow mselect7 to operate in filter mode. This change requires herdtools 7.52-32-g1da3e0e50977 or later. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

2023-03-24tools/memory-model: Fix scripting --jobs argumentPaul E. McKenney

2023-03-24tools/memory-model: Implement --hw support for checkghlitmus.shPaul E. McKenney
This commits enables the "--hw" argument for the checkghlitmus.sh script, causing it to convert any applicable C-language litmus tests to the specified flavor of assembly language, to verify these assembly-language litmus tests, and checking compatibility of the outcomes. Note that the conversion does not yet handle locking, RCU, SRCU, plain C-language memory accesses, or casts. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Add -v flag to jingle7 runsPaul E. McKenney

2023-03-24tools/memory-model: Allow herd to deduce CPU typePaul E. McKenney
Currently, the scripts specify the CPU's .cat file to herd. But this is pointless because herd will select a good and sufficient .cat file from the assembly-language litmus test itself. This commit therefore removes the -model argument to herd, allowing herd to figure the CPU family out itself. Note that the user can override herd's choice using the "--herdopts" argument to the scripts. Suggested-by: Luc Maranget <luc.maranget@inria.fr> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
2023-03-24tools/memory-model: Keep assembly-language litmus testsPaul E. McKenney
This commit retains the assembly-language litmus tests generated from the C-language litmus tests, appending the hardware tag to the original C-language litmus test's filename. Thus, S+poonceonces.litmus.AArch64 contains the Armv8 assembly language corresponding to the C-language S+poonceonces.litmus test. This commit also updates the .gitignore to avoid committing these automatically generated assembly-language litmus tests. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
