fs: implement kernel_write using __kernel_write
Consolidate the two in-kernel write helpers to make upcoming changes easier. The only difference are the missing call to rw_verify_area in kernel_write, and an access_ok check that doesn't make sense for kernel buffers to start with. Signed-off-by: Christoph Hellwig <hch@lst.de> |

fs: check FMODE_WRITE in __kernel_write
Add a WARN_ON_ONCE if the file isn't actually open for write. This matches the check done in vfs_write, but actually warn warns as a kernel user calling write on a file not opened for writing is a pretty obvious programming error. Signed-off-by: Christoph Hellwig <hch@lst.de> |

fs: unexport __kernel_write
This is a very special interface that skips sb_writes protection, and not used by modules anymore. Signed-off-by: Christoph Hellwig <hch@lst.de> |

bpfilter: switch to kernel_write
While pipes don't really need sb_writers projection, __kernel_write is an interface better kept private, and the additional rw_verify_area does not hurt here. Signed-off-by: Christoph Hellwig <hch@lst.de> |

Second batch of perf tooling fixes for v5.8:
- Intel PT fixes for PEBS-via-PT with registers.
- Fixes for Intel PT python based GUI.
- Avoid duplicated sideband events with Intel PT in system wide tracing.
- Remove needless 'dummy' event from TUI menu, used when synthesizing
meta data events for pre-existing processes.
- Fix corner case segfault when pressing enter in a screen without
entries in the TUI for report/top.
- Fixes for time stamp handling in libtraceevent.
- Explicitly set utf-8 encoding in perf flamegraph.
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy',
silencing perf build warning.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

perf report TUI: Remove needless 'dummy' event from menu
Fixing the common case of: perf record perf report And getting just the cycles events. We now have a 'dummy' event to get perf metadata events that take place while we synthesize metadata records for pre-existing processes by traversing procfs, so we always have this extra 'dummy' evsel, but we don't have to offer it as there will be no samples on it, remove this distraction.

perf intel-pt: Fix displaying PEBS-via-PT with registers
After recording PEBS-via-PT, perf script will not accept 'iregs' field e.g.

...
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.062 MB perf.data ]
# ./perf script --itrace=eop -F+iregs
Samples for 'dummy:u' event do not have IREGS attribute set. Cannot print 'iregs' field.
Fix by using allow_user_set, which is true when recording AUX area data.

perf intel-pt: Fix recording PEBS-via-PT with registers
When recording PEBS-via-PT, the kernel will not accept the intel_pt
event with register sampling e.g.
# perf record --kcore -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l
Error:
intel_pt/branch=0/: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat'
Fix by suppressing register sampling on the intel_pt evsel.
Committer notes:
Adrian informed that this is only available from Tremont onwards, so on
older processors the error continues the same as before.

perf report TUI: Fix segmentation fault in perf_evsel__hists_browse()
The segmentation fault can be reproduced as following steps:
1) Executing perf report in tui.
2) Typing '/xxxxx' to filter the symbol to get nothing matched.
3) Pressing enter with no entry selected.
Then it will report a segmentation fault.
It is caused by the lack of check of browser->he_selection when
accessing it's member res_samples in perf_evsel__hists_browse().
These processes are meaningful for specified samples, so we can skip
these when nothing is selected.

x86/ldt: use "pr_info_once()" instead of open-coding it badly
Using a mutex for "print this warning only once" is so overdesigned as to be actively offensive to my sensitive stomach. Just use "pr_info_once()" that already does this, although in a (harmlessly) racy manner that can in theory cause the message to be printed twice if more than one CPU races on that "is this the first time" test. [ If somebody really cares about that harmless data race (which sounds very unlikely indeed), that person can trivially fix printk_once() by using a simple atomic access, preferably with an optimistic non-atomic test first before even bothering to treat the pointless "make sure it is _really_ just once" case. A mutex is most definitely never the right primitive to use for something like this. ] Yes, this is a small and meaningless detail in a code path that hardly matters. But let's keep some code quality standards here, and not accept outrageously bad code.

A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user space
value.
- Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
whitelisted for split lock detection. Some CPUs which do not support
it crash even when the MSR is written to 0 which is the default value.
- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework
- Add more selftests to ensure that these entry problems don't come back.
- Disable 16 bit segments on XEN PV. It's not supported because XEN PV
does not implement ESPFIX64

Pull x86 fixes from Thomas Gleixner:
"A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user
space value.
- Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
whitelisted for split lock detection. Some CPUs which do not
support it crash even when the MSR is written to 0 which is the
default value.
- Fix the XEN PV fallout of the entry code rework
- Fix the 32bit fallout of the entry code rework
- Add more selftests to ensure that these entry problems don't come
back.
- Disable 16 bit segments on XEN PV. It's not supported because XEN
PV does not implement ESPFIX64"

A set of interrupt chip driver fixes:
- Ensure the atomicity of affinity updates in the GIC driver.
- Don't try to sleep in atomic context when waiting for the GICv4.1 to
respond. Use polling instead.

MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen
This resolves the hazard between the mtc0 in the change_c0_status() and the mfc0 in configure_exception_vector(). Without resolving this hazard configure_exception_vector() could read an old value and would restore this old value again. This would revert the changes change_c0_status() did. I checked this by printing out the read_c0_status() at the end of per_cpu_trap_init() and the ST0_MX is not set without this patch. The hazard is documented in the MIPS Architecture Reference Manual Vol. III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev 6.03 table 8.1 which includes: Producer | Consumer | Hazard ----------|----------|---------------------------- mtc0 | mfc0 | any coprocessor 0 register I saw this hazard on an Atheros AR9344 rev 2 SoC with a MIPS 74Kc CPU. There the change_c0_status() function would activate the DSPen by setting ST0_MX in the c0_status register. This was reverted and then the system got a DSP exception when the DSP registers were saved in save_dsp() in the first process switch. The crash looks like this: [ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) [ 0.107070] Kernel panic - not syncing: Unexpected DSP exception [ 0.113470] Rebooting in 1 seconds.. We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs, not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it did not happen. In the kernel I bisected this problem to commit |

io_uring: fix regression with always ignoring signals in io_cqring_wait()
When switching to TWA_SIGNAL for task_work notifications, we also made
any signal based condition in io_cqring_wait() return -ERESTARTSYS.
This breaks applications that rely on using signals to abort someone
waiting for events.
Check if we have a signal pending because of queued task_work, and
repeat the signal check once we've run the task_work. This provides a
reliable way of telling the two apart.
Additionally, only use TWA_SIGNAL if we are using an eventfd. If not,
we don't have the dependency situation described in the original commit,
and we can get by with just using TWA_RESUME like we previously did.

x86/ldt: Disable 16-bit segments on Xen PV
Xen PV doesn't implement ESPFIX64, so they don't work right. Disable them. Also print a warning the first time anyone tries to use a 16-bit segment on a Xen PV guest that would otherwise allow it to help people diagnose this change in behavior.

x86/entry/32: Fix #MC and #DB wiring on x86_32
DEFINE_IDTENTRY_MCE and DEFINE_IDTENTRY_DEBUG were wired up as non-RAW on x86_32, but the code expected them to be RAW. Get rid of all the macro indirection for them on 32-bit and just use DECLARE_IDTENTRY_RAW and DEFINE_IDTENTRY_RAW directly. Also add a warning to make sure that we only hit the _kernel paths in kernel mode.

x86/entry/xen: Route #DB correctly on Xen PV
On Xen PV, #DB doesn't use IST. It still needs to be correctly routed
depending on whether it came from user or kernel mode.
Get rid of DECLARE/DEFINE_IDTENTRY_XEN -- it was too hard to follow the
logic. Instead, route #DB and NMI through DECLARE/DEFINE_IDTENTRY_RAW on
Xen, and do the right thing for #DB. Also add more warnings to the
exc_debug* handlers to make this type of failure more obvious.
This fixes various forms of corruption that happen when usermode
triggers #DB on Xen PV.
