2023-05-29RDMA/irdma: Fix Local Invalidate fencingMustafa Ismail
If the local invalidate fence is indicated in the WR, only the read fence is currently being set in WQE. Fix this to set both the read and local fence in the WQE.

2023-05-29RDMA/irdma: Prevent QP use after freeMustafa Ismail
There is a window where the poll cq may use a QP that has been freed. This can happen if a CQE is polled before irdma_clean_cqes() can clear the CQE's related to the QP and the destroy QP races to free the QP memory. then the QP structures are used in irdma_poll_cq. Fix this by moving the clearing of CQE's before the reference is removed and the QP is destroyed.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: "User events: - Use long instead of int for storing the enable set/clear bit, as it was found that big endian machines could end up using the wrong bits. - Split allocating mm and attaching it. This keeps the allocation separate from the registration and avoids various races. - Remove RCU locking around pin_user_pages_remote() as that can schedule. The RCU protection is no longer needed with the above split of mm allocation and attaching. - Rename the "link" fields of the various structs to something more meaningful. - Add comments around user_event_mm struct usage and locking requirements. Timerlat tracer: - Fix missed wakeup of timerlat thread caused by the timerlat interrupt triggering when tracing is off. The timer interrupt handler needs to always wake up the timerlat thread regardless if tracing is enabled or not, otherwise, it will never wake up. Histograms: - Fix regression of breaking the "stacktrace" modifier for variables. That modifier cannot be used for values, but can be used for variables that are passed from one histogram to the next. This was broken when adding the restriction to values as the variable logic used the same code. - Rename the special field "stacktrace" to "common_stacktrace". Special fields (that are not actually part of the event, but can act just like event fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for consistency. To keep backward compatibility, 'stacktrace' can still be used (as with the special field 'cpu'), but can be overridden if the event has a field called 'stacktrace'. - Update the synthetic event selftests to use the new name (synthetic events are created by histograms) Tracing bootup selftests: - Reorganize the code to keep artifacts of the selftests not compiled in when selftests are not configured. - Add various cond_resched() around the selftest code, as the softlock watchdog was triggering much more often. It appears that the kernel runs slower now with full debugging enabled. - While debugging ftrace with ftrace (using an instance ring buffer instead of the top level one), I found that the selftests were disabling prints to the debug instance. This should not happen, as the selftests only disable printing to the main buffer as the selftests examine the main buffer to see if it has what it expects, and prints can make the tests fail.

2023-05-29Revert "module: error out early on concurrent load of the same module file"Linus Torvalds
This reverts commit 9828ed3f695a138f7add89fa2a186ababceb8006. Sadly, it does seem to cause failures to load modules. Johan Hovold reports: "This change breaks module loading during boot on the Lenovo Thinkpad X13s (aarch64). Specifically it results in indefinite probe deferral of the display and USB (ethernet) which makes it a pain to debug. Typing in the dark to acquire some logs reveals that other modules are missing as well" Since this was applied late as a "let's try this", I'm reverting it asap, and we can try to figure out what goes wrong later. The excessive parallel module loading problem is annoying, but not noticeable in normal situations, and this was only meant as an optimistic workaround for a user-space bug. One possible solution may be to do the optimistic exclusive open first, and then use a lock to serialize loading if that fails.

2023-05-28tracing: Have function_graph selftest call cond_resched()Steven Rostedt (Google)
When all kernel debugging is enabled (lockdep, KSAN, etc), the function graph enabling and disabling can take several seconds to complete. The function_graph selftest enables and disables function graph tracing several times. With full debugging enabled, the soft lockup watchdog was triggering because the selftest was running without ever scheduling. Add cond_resched() throughout the test to make sure it does not trigger the soft lockup detector.

2023-05-28tracing: Only make selftest conditionals affect the global_traceSteven Rostedt (Google)
The tracing_selftest_running and tracing_selftest_disabled variables were to keep trace_printk() and other writes from affecting the tracing selftests, as the tracing selftests would examine the ring buffer to see if it contained what it expected or not. trace_printk() and friends could add to the ring buffer and cause the selftests to fail (and then disable the tracer that was being tested). To keep that from happening, these variables were added and would keep trace_printk() and friends from writing to the ring buffer while the tests were going on. But this was only the top level ring buffer (owned by the global_trace instance). There is no reason to prevent writing into ring buffers of other instances via the trace_array_printk() and friends. For the functions that could be used by other instances, check if the global_trace is the tracer instance that is being written to before deciding to not allow the write.

2023-05-28tracing: Have tracer selftests call cond_resched() before runningSteven Rostedt (Google)
As there are more and more internal selftests being added to the Linux kernel (KSAN, lockdep, etc) the selftests are taking longer to run when these are enabled. Add a cond_resched() to the calling of do_run_tracer_selftest() to force a schedule if NEED_RESCHED is set, otherwise the soft lockup watchdog may trigger on boot up.

2023-05-28tracing: Move setting of tracing_selftest_running out of register_tracer()Steven Rostedt (Google)
The variables tracing_selftest_running and tracing_selftest_disabled are only used for when CONFIG_FTRACE_STARTUP_TEST is enabled. Make them only visible within the selftest code. The setting of those variables are in the register_tracer() call, and set in a location where they do not need to be. Create a wrapper around run_tracer_selftest() called do_run_tracer_selftest() which sets those variables, and have register_tracer() call that instead. Having those variables only set within the CONFIG_FTRACE_STARTUP_TEST scope gets rid of them (and also the ability to remove testing against them) when the startup tests are not enabled (most cases).

2023-05-28ext4: add EA_INODE checking to ext4_iget()Theodore Ts'o
Add a new flag, EXT4_IGET_EA_INODE which indicates whether the inode is expected to have the EA_INODE flag or not. If the flag is not set/clear as expected, then fail the iget() operation and mark the file system as corrupted. This commit also makes the ext4_iget() always perform the is_bad_inode() check even when the inode is already inode cache. This allows us to remove the is_bad_inode() check from the callers of ext4_iget() in the ea_inode code.

However, this doesn't make much sense, since i == 1 and num_pages == 1 doesn't execute the body of the loop. In addition, i < num_pages can also ensure that buf->pages[i] will not cross the boundary. Unfortunately, this doesn't help with the problem observed here: gcc still complains. To fix this add a compile-time condition for the extent buffer page array size limit, which would eventually lead to eliminating the whole for loop.

2023-05-26btrfs: call btrfs_orig_bbio_end_io in btrfs_end_bio_workChristoph Hellwig
When I implemented the storage layer bio splitting, I was under the assumption that we'll never split metadata bios. But Qu reminded me that this can actually happen with very old file systems with unaligned metadata chunks and RAID0. I still haven't seen such a case in practice, but we better handled this case, especially as it is fairly easily to do not calling the ->end_іo method directly in btrfs_end_io_work, and using the proper btrfs_orig_bbio_end_io helper instead. In addition to the old file system with unaligned metadata chunks case documented in the commit log, the combination of the new scrub code with Johannes pending raid-stripe-tree also triggers this case. We spent some time debugging it and found that this patch solves the problem.

2023-05-26cxl: Explicitly initialize resources when media is not readyDave Jiang
When media is not ready do not assume that the capacity information from the identify command is valid, i.e. ->total_bytes ->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly zero out the capacity resources and exit early. Given zero-init of those fields this patch is functionally equivalent to the prior state, but it improves readability and robustness going forward.

2023-05-26x86: re-introduce support for ERMS copies for user space accessesLinus Torvalds
I tried to streamline our user memory copy code fairly aggressively in commit adfcf4231b8c ("x86: don't use REP_GOOD or ERMS for user memory copies"), in order to then be able to clean up the code and inline the modern FSRM case in commit 577e6a7fd50d ("x86: inline the 'rep movs' in user copies for the FSRM case"). We had reports [1] of that causing regressions earlier with blogbench, but that turned out to be a horrible benchmark for that case, and not a sufficient reason for re-instating "rep movsb" on older machines. However, now Eric Dumazet reported [2] a regression in performance that seems to be a rather more real benchmark, where due to the removal of "rep movs" a TCP stream over a 100Gbps network no longer reaches line speed. And it turns out that with the simplified the calling convention for the non-FSRM case in commit 427fda2c8a49 ("x86: improve on the non-rep 'copy_user' function"), re-introducing the ERMS case is actually fairly simple. Of course, that "fairly simple" is glossing over several missteps due to having to fight our assembler alternative code. This code really wanted to rewrite a conditional branch to have two different targets, but that made objtool sufficiently unhappy that this instead just ended up doing a choice between "jump to the unrolled loop, or use 'rep movsb' directly". Let's see if somebody finds a case where the kernel memory copies also care (see commit 68674f94ffc9: "x86: don't use REP_GOOD or ERMS for small memory copies"). But Eric does argue that the user copies are special because networking tries to copy up to 32KB at a time, if order-3 pages allocations are possible. In-kernel memory copies are typically small, unless they are the special "copy pages at a time" kind that still use "rep movs".
