2021-09-27perf iostat: Fix Segmentation fault from NULL 'struct perf_counts_values *'Like Xu
If the 'perf iostat' user specifies two or more iio_root_ports and also specifies the cpu(s) by -C which is not *connected to all* the above iio ports, the iostat_print_metric() will run into trouble: For example: $ perf iostat list S0-uncore_iio_0<0000:16> S1-uncore_iio_0<0000:97> # <--- CPU 1 is located in the socket S0 $ perf iostat 0000:16,0000:97 -C 1 -- ls port Inbound Read(MB) Inbound Write(MB) Outbound Read(MB) Outbound Write(MB) ../perf-iostat: line 12: 104418 Segmentation fault (core dumped) perf stat --iostat$DELIMITER$* The core-dump stack says, in the above corner case, the returned (struct perf_counts_values *) count will be NULL, and the caller iostat_print_metric() apparently doesn't not handle this case. 433 struct perf_counts_values *count = perf_counts(evsel->counts, die, 0); 434 435 if (count->run && count->ena) { (gdb) p count $1 = (struct perf_counts_values *) 0x0 The deeper reason is that there are actually no statistics from the user specified pair "iostat 0000:X, -C (disconnected) Y ", but let's fix it with minimum cost by adding a NULL check in the user space.

2021-09-27perf iostat: Use system-wide mode if the target cpu_list is unspecifiedLike Xu
An iostate use case like "perf iostat 0000:16,0000:97 -- ls" should be implemented to work in system-wide mode to ensure that the output from print_header() is consistent with the user documentation perf-iostat.txt, rather than incorrectly assuming that the kernel does not support it: Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) \ for event (uncore_iio_0/event=0x83,umask=0x04,ch_mask=0xF,fc_mask=0x07/). /bin/dmesg | grep -i perf may provide additional information. This error is easily fixed by assigning system-wide mode by default for IOSTAT_RUN only when the target cpu_list is unspecified.

2021-09-27perf config: Refine error message to eliminate confusionLike Xu
If there is no configuration file at first, the user can write any pair of "key.subkey=value" to the newly created configuration file, while value validation against a valid configurable key is *deferred* until the next execution or the implied execution of "perf config ... ". For example: $ rm ~/.perfconfig $ perf config call-graph.dump-size=65529 $ cat ~/.perfconfig # this file is auto-generated. [call-graph] dump-size = 65529 $ perf config call-graph.dump-size=2048 callchain: Incorrect stack dump size (max 65528): 65529 Error: wrong config key-value pair call-graph.dump-size=65529 The user might expect that the second value 2048 is valid and can be updated to the configuration file, but the error message is very confusing because the first value 65529 is not reported as an error during the last configuration. It is recommended not to change the current behavior of delayed validation (as more effort is needed), but to refine the original error message to *clearly indicate* that the cause of the error is the configuration file.

2021-09-27perf tests: Fix flaky test 'Object code reading'James Clark
This test occasionally fails on aarch64 when a sample is taken in free@plt and it fails with "Bytes read differ from those read by objdump". This is because that symbol is near a section boundary in the elf file. Despite the -z option to always output zeros, objdump uses bfd_map_over_sections() to iterate through the elf file so it doesn't see outside of the sections where these zeros are and can't print them. For example this boundary proceeds free@plt in libc with a gap of 48 bytes between .plt and .text: objdump -d -z --start-address=0x23cc8 --stop-address=0x23d08 libc-2.30.so libc-2.30.so: file format elf64-littleaarch64 Disassembly of section .plt: 0000000000023cc8 <*ABS*+0x7fd00@plt+0x8>: 23cc8: 91018210 add x16, x16, #0x60 23ccc: d61f0220 br x17 Disassembly of section .text: 0000000000023d00 <abort@@GLIBC_2.17-0x98>: 23d00: a9bf7bfd stp x29, x30, [sp, #-16]! 23d04: 910003fd mov x29, sp Taking a sample in free@plt is very rare because it is so small, but the test can be forced to fail almost every time on any platform by linking the test with a shared library that has a single empty function and calling it in a loop. The fix is to zero the buffers so that when there is a jump in the addresses output by objdump, zeros are already filled in between.

2021-09-27perf test: Fix DWARF unwind for optimized builds.Ian Rogers
To ensure the stack frames are on the stack tail calls optimizations need to be inhibited. If your compiler supports an attribute use it, otherwise use an asm volatile barrier. The barrier fix was suggested here: https://lore.kernel.org/lkml/20201028081123.GT2628@hirez.programming.kicks-ass.net/ Tested with an optimized clang build and by forcing the asm barrier route with an optimized clang build. A GCC bug tracking a proper disable_tail_calls is: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97831 Fixes: 9ae1e990f1ab ("perf tools: Remove broken __no_tail_call attribute") v2. is a rebase. The original fix patch generated quite a lot of discussion over the right place for the fix: https://lore.kernel.org/lkml/20201114000803.909530-1-irogers@google.com/ The patch reflects my preference of it being near the use, so that future code cleanups don't break this somewhat special usage.

2021-09-27spi: cadence: add support for Cadence XSPI controllerParshuram Thombare
This patch adds driver for Cadence's XSPI controller. It supports 3 work modes. 1. ACMD (auto command) work mode ACMD name is because it uses auto command engine in the controller. It further has 2 modes PIO and CDMA (command DMA). The CDMA work mode is dedicated for high-performance application where very low software overhead is required. In this mode the Command Engine is programmed by the series of linked descriptors stored in system memory. These descriptors provide commands to execute and store status information for finished commands. The PIO mode work mode is dedicated for single operation where constructing a linked list of descriptors would require too much effort. 2. STIG (Software Triggered Instruction Generator) work mode In STIG mode, controller sends low-level instructions to memory. Each instruction is 128-bit width. There is special instruction DataSequence which carries information about data phase. Driver uses Slave DMA interface to transfer data as only this interface can be used in STIG work mode. 3. Direct work mode This work mode allows sending data without invoking any command through the slave interface. Currently only STIG work mode is enabled, remaining work modes will be added later.

2021-09-27s390/cio: avoid excessive path-verification requestsVineeth Vijayan
Currently when removing a device from cio_ignore list, we trigger a path-verification for all the subchannels available in the system.

2021-09-27net: bgmac-platform: handle mac-address deferralMatthew Hagan
This patch is a replication of Christian Lamparter's "net: bgmac-bcma: handle deferred probe error due to mac-address" patch for the bgmac-platform driver [1]. As is the case with the bgmac-bcma driver, this change is to cover the scenario where the MAC address cannot yet be discovered due to reliance on an nvmem provider which is yet to be instantiated, resulting in a random address being assigned that has to be manually overridden.

2021-09-27mac80211: fix use-after-free in CCMP/GCMP RXJohannes Berg
When PN checking is done in mac80211, for fragmentation we need to copy the PN to the RX struct so we can later use it to do a comparison, since commit bf30ca922a0c ("mac80211: check defrag PN against current frame"). Unfortunately, in that commit I used the 'hdr' variable without it being necessarily valid, so use-after-free could occur if it was necessary to reallocate (parts of) the frame. Fix this by reloading the variable after the code that results in the reallocations, if any. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=214401.

In commit 4e5c8a99e1cb ("drm/i915: Drop i915_request.lock requirement for intel_rps_boost()"), we decoupled the rps worker from the pm so that we could avoid the synchronization penalty which makes the assertion liable to run too early.

2021-09-27drm/i915/request: fix early tracepointsMatthew Auld
Currently we blow up in trace_dma_fence_init, when calling into get_driver_name or get_timeline_name, since both the engine and context might be NULL(or contain some garbage address) in the case of newly allocated slab objects via the request ctor. Note that we also use SLAB_TYPESAFE_BY_RCU here, which allows requests to be immediately freed, but delay freeing the underlying page by an RCU grace period. With this scheme requests can be re-allocated, at the same time as they are also being read by some lockless RCU lookup mechanism. In the ctor case, which is only called for new slab objects(i.e allocate new page and call the ctor for each object) it's safe to reset the context/engine prior to calling into dma_fence_init, since we can be certain that no one is doing an RCU lookup which might depend on peeking at the engine/context, like in active_engine(), since the object can't yet be externally visible. In the recycled case(which might also be externally visible) the request refcount always transitions from 0->1 after we set the context/engine etc, which should ensure it's valid to dereference the engine for example, when doing an RCU list-walk, so long as we can also increment the refcount first. If the refcount is already zero, then the request is considered complete/released. If it's non-zero, then the request might be in the process of being re-allocated, or potentially still in flight, however after successfully incrementing the refcount, it's possible to carefully inspect the request state, to determine if the request is still what we were looking for. Note that all externally visible requests returned to the cache must have zero refcount. One possible fix then is to move dma_fence_init out from the request ctor. Originally this was how it was done, but it was moved in: commit 855e39e65cfc33a73724f1cc644ffc5754864a20 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Feb 3 09:41:48 2020 +0000 drm/i915: Initialise basic fence before acquiring seqno where it looks like intel_timeline_get_seqno() relied on some of the rq->fence state, but that is no longer the case since: commit 12ca695d2c1ed26b2dcbb528b42813bd0f216cfc Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Tue Mar 23 16:49:50 2021 +0100 drm/i915: Do not share hwsp across contexts any more, v8. intel_timeline_get_seqno() could also be cleaned up slightly by dropping the request argument. Moving dma_fence_init back out of the ctor, should ensure we have enough of the request initialised in case of trace_dma_fence_init. Functionally this should be the same, and is effectively what we were already open coding before, except now we also assign the fence->lock and fence->ops, but since these are invariant for recycled requests(which might be externally visible), and will therefore already hold the same value, it shouldn't matter. An alternative fix, since we don't yet have a fully initialised request when in the ctor, is just setting the context/engine as NULL, but this does require adding some extra handling in get_driver_name etc. v2(Daniel): - Try to make the commit message less confusing Fixes: 855e39e65cfc ("drm/i915: Initialise basic fence before acquiring seqno") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Michael Mason <michael.w.mason@intel.com> Cc: Daniel Vetter <daniel@ffwll.ch> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210921134202.3803151-1-matthew.auld@intel.com (cherry picked from commit be988eaee1cb208c4445db46bc3ceaf75f586f0b) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2021-09-26ksmbd: remove RFC1002 check in smb2 requestRonnie Sahlberg
In smb_common.c you have this function : ksmbd_smb_request() which is called from connection.c once you have read the initial 4 bytes for the next length+smb2 blob. It checks the first byte of this 4 byte preamble for valid values, i.e. a NETBIOSoverTCP SESSION_MESSAGE or a SESSION_KEEP_ALIVE. We don't need to check this for ksmbd since it only implements SMB2 over TCP port 445. The netbios stuff was only used in very old servers when SMB ran over TCP port 139. Now that we run over TCP port 445, this is actually not a NB header anymore and you can just treat it as a 4 byte length field that must be less than 16Mbyte. and remove the references to the RFC1002 constants that no longer applies.
