The clk rate is always stored in clk_core but might be out of date and require calls to update from hardware. Deal with that case by printing a (c) suffix. Link: http://lkml.kernel.org/r/1a474318982a5f0125f2360c4161029b17f56bd1.1556881728.git.leonard.crestez@nxp.comSigned-off-by:

An incorrect argument to list_for_each is an internal error in gdb scripts so a TypeError should be raised. The gdb.GdbError exception type is intended for user errors such as incorrect invocation. Drop the type assertion in list_for_each_entry because list_for_each isn't going to suddenly yield something else. Applies to both list and hlist Link: http://lkml.kernel.org/r/c1d3fd4db13d999a3ba57f5bbc1924862d824f61.1556881728.git.leonard.crestez@nxp.comSigned-off-by:

lx-configdump <file> dumps the contents of the gzipped .config to a text file when the config is included in the kernel with CONFIG_IKCONFIG. By default, the file written is called config.txt, but it can be any user supplied filename as well. If the kernel config is in a module (configs.ko), then it can be loaded along with symbols for the module loaded with 'lx-symbols' and then this command will still work. Obviously if you have the whole vmlinux then this can also be achieved with scripts/extract-ikconfig, but this gdb script can be useful to confirm that the memory contents of the config in memory and the vmlinux contents on disk match what is expected.

Patch series "gdb script for kconfig and timer list". This is a handful of changes to the kernel's gdb scripts to do some more debugging with kgdb. The first patch allows the vmlinux to be reloaded from where it was specified on the command line so that this set of scripts can be used from anywhere. The second patch adds a script to dump the config.gz to a file on the host debugging machine. The third patch adds some rb tree utilities and the last patch uses those rb tree walking utilities to dump out the contents of /proc/timer_list from a system under debug. This patch (of 5): If I run 'gdb <path/to/vmlinux>' and there's the vmlinux-gdb.py file there I can properly see symbols and use the lx commands provided by the GDB scripts. But once I run 'lx-symbols' at the command prompt, gdb reloads the vmlinux symbols assuming that this script was run from the directory that has vmlinux at the root. That isn't always true, but we could just look and see what symbols were already loaded and use that instead. Let's do that so this can work by being invoked anywhere.

When kernel panic happens, it will first print the panic call stack, then the ending msg like: [ 35.743249] ---[ end Kernel panic - not syncing: Fatal exception [ 35.749975] ------------[ cut here ]------------ The above message are very useful for debugging. But if system is configured to not reboot on panic, say the "panic_timeout" parameter equals 0, it will likely print out many noisy message like WARN() call stack for each and every CPU except the panic one, messages like below: WARNING: CPU: 1 PID: 280 at kernel/sched/core.c:1198 set_task_cpu+0x183/0x190 Call Trace: <IRQ> try_to_wake_up default_wake_function autoremove_wake_function __wake_up_common __wake_up_common_lock __wake_up wake_up_klogd_work_func irq_work_run_list irq_work_tick update_process_times tick_sched_timer __hrtimer_run_queues hrtimer_interrupt smp_apic_timer_interrupt apic_timer_interrupt For people working in console mode, the screen will first show the panic call stack, but immediately overridden by these noisy extra messages, which makes debugging much more difficult, as the original context gets lost on screen. Also these noisy messages will confuse some users, as I have seen many bug reporters posted the noisy message into bugzilla, instead of the real panic call stack and context. Adding a flag "suppress_printk" which gets set in panic() to avoid those noisy messages, without changing current kernel behavior that both panic blinking and sysrq magic key can work as is, suggested by Petr Mladek. To verify this, make sure kernel is not configured to reboot on panic and in console # echo c > /proc/sysrq-trigger to see if console only prints out the panic call stack.

LLVM uses profiling data that's deliberately similar to GCC, but has a very different way of exporting that data. LLVM calls llvm_gcov_init() once per module, and provides a couple of callbacks that we can use to ask for more data. We care about the "writeout" callback, which in turn calls back into compiler-rt/this module to dump all the gathered coverage data to disk: llvm_gcda_start_file() llvm_gcda_emit_function() llvm_gcda_emit_arcs() llvm_gcda_emit_function() llvm_gcda_emit_arcs() [... repeats for each function ...] llvm_gcda_summary_info() llvm_gcda_end_file() This design is much more stateless and unstructured than gcc's, and is intended to run at process exit. This forces us to keep some local state about which module we're dealing with at the moment. On the other hand, it also means we don't depend as much on how LLVM represents profiling data internally. See LLVM's lib/Transforms/Instrumentation/GCOVProfiling.cpp for more details on how this works, particularly GCOVProfiler::emitProfileArcs(), GCOVProfiler::insertCounterWriteout(), and GCOVProfiler::insertFlush().

Finding endpoints of an IPC channel is one of essential task to understand how a user program works. Procfs and netlink socket provide enough hints to find endpoints for IPC channels like pipes, unix sockets, and pseudo terminals. However, there is no simple way to find endpoints for an eventfd file from userland. An inode number doesn't hint. Unlike pipe, all eventfd files share the same inode object. To provide the way to find endpoints of an eventfd file, this patch adds "eventfd-id" field to /proc/PID/fdinfo of eventfd as identifier. Integers managed by an IDA are used as ids. A tool like lsof can utilize the information to print endpoints. Link: http://lkml.kernel.org/r/20190327181823.20222-1-yamato@redhat.comSigned-off-by:

Today, proc_do_large_bitmap() truncates a large write input buffer to PAGE_SIZE - 1, which may result in misparsed numbers at the (truncated) end of the buffer. Further, it fails to notify the caller that the buffer was truncated, so it doesn't get called iteratively to finish the entire input buffer. Tell the caller if there's more work to do by adding the skipped amount back to left/*lenp before returning. To fix the misparsing, reset the position if we have completely consumed a truncated buffer (or if just one char is left, which may be a "-" in a range), and ask the caller to come back for more.

The kernel has only two users of proc_do_large_bitmap(), the kernel CPU watchdog, and the ip_local_reserved_ports. Refer to watchdog_cpumask and ip_local_reserved_ports in Documentation for further details on these. When you input a large buffer into these, when it is larger than PAGE_SIZE- 1, the input data gets misparsed, and the user get incorrectly informed that the desired input value was set. This commit implements a test which mimics and exploits that use case, it uses a bitmap size, as in the watchdog case. The bitmap is used to test the bitmap proc handler, proc_do_large_bitmap(). The next commit fixes this issue.

On old kernels older new test knobs implemented on the test_sysctl module may not be available. This is expected, and the selftests test scripts should be able to run without failures on older kernels. Generalize a solution so that we test for each required test target file for each test by requiring each test description to annotate their respective test target file. If the target file does not exist, we skip the test gracefully. Link: http://lkml.kernel.org/r/20190320222831.8243-5-mcgrof@kernel.orgSigned-off-by:

When verify_diff_w() is used we care about the result, not the verbose output, and although we use -q, that still gives us a chatty message about if the files differ or not. Since verify_diff_w() uses stdinput the chatty message says whether or not "-" matches the target file, and this just seems rather odd. Better to just ignore that messsage all together, what we really care about i sthe results, the return value and we check for that.

Patch series "sysctl: add pending proc_do_large_bitmap fix". Eric sent a fix out for proc_do_large_bitmap() last month for when using a large input buffer. After patch review a test case for the issue was built and submitted. I noticed there were a few issues with the tests, but instead of just asking Eric to address them I've taken care of them and ammended the commit where necessary. There's a few issues he reported which I also address and fix in this series. Since we *do* expect users of these scripts to also use them on older kernels, I've also addressed not breaking calling the script for them, and gives us an easy way to easily extend our tests cases for future kernels as well. Before anyone considers these for stable as minor fixes, I'd recommend we also address the discrepancy on the read side of things: modify the test script to use diff against the target file instead of using the temp file. This patch (of 6): We already call test_reqs(), no need to call it twice. Link: http://lkml.kernel.org/r/20190320222831.8243-2-mcgrof@kernel.orgSigned-off-by:

It means that on x86_64 all accesses to other fields will go though [r64 + disp32] addressing mode which is 3 bytes bloatier than [r64 + disp8] addressing mode. Given that accesses to other fields outnumber accesses to ->buf, move it down.

fsync() needs to make sure the data & meta-data of file are persistent after the return of fsync(), even when a power-failure occurs later. In the case of fat-fs, the FAT belongs to the meta-data of file, so we need to issue a flush after the writeback of FAT instead before. Also bail out early when any stage of fsync fails.

csum_partial() gives different results for little-endian and big-endian hosts. This causes images created on little-endian hosts and mounted on big endian hosts to see csum mismatches. This causes an endianness bug. Sparse gives a warning as csum_partial returns a restricted integer type __wsum_t and xattr_hash expects __u32. This warning acts as a reminder for this bug and should not be suppressed. This comment aims to convey these endianness issues.
