Fix memory leak in hashmap_clear() not freeing hashmap_entry structs for each
of the remaining entries. Also NULL-out bucket list to prevent possible
double-free between hashmap__clear() and hashmap__free().
Running test_progs-asan flavor clearly showed this problem.
Repor
Perf's expr code currently builds an array of strings then removes
duplicates. The array is larger than necessary and has recently been
increased in size. When this was done it was commented that a hashmap
would be preferable.
libbpf has a hashmap but libbpf isn't currently required to build
perf.
Break pmu-events test into 2 and add a test to verify that all pmu
metric expressions simply parse. Try to parse all metric ids/events,
skip/warn if metrics for the current architecture fail to parse. To
support warning for a skip, and an ability for a subtest to describe why
it skips.
Tested on p
Now subtests can inform why a test was skipped. The upcoming patch
improvint PMU event metric testing will use it.

Use a hashmap between a char* string and a double* value. While bpf's
hashmap entries are size_t in size, we can't guarantee sizeof(size_t) >=
sizeof(double). Avoid a memory allocation when gathering ids by making 0.0
a special value encoded as NULL.
Original map suggestion by Andi Kleen:
https://
Allow use of hashmap in perf. Modify perf's check-headers.sh script to
check that the files are kept in sync, in the same way kernel headers are
checked. This will warn if they are out of sync at the start of a perf
build.

The comparison of hcd->irq to less than zero for an error check will
never be true because hcd->irq is an unsigned int. Fix this by
assigning the int retval to the return of platform_get_irq and checking
this for the -ve error condition and assigning hcd->irq to retval.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};

Hi all,
Here's a series of cleanups I hacked together on top of a modified v13
of the Shadow Call Stack patches from Sami:
https://lore.kernel.org/r/20200515172355.GD23334@willie-the-truck
The main changes are:
* Move code out of arch/arm64 and into the core implementation
* Store the ful
There's no need to perform the shadow stack page accounting independently
of the lifetime of the underlying allocation, so call the accounting code
from the {alloc,free}() functions and simplify the code in the process.

There is nothing architecture-specific about scs_overflow_check() as
it's just a trivial wrapper around scs_corrupted().
For parity with task_stack_end_corrupted(), rename scs_corrupted() to
task_scs_end_corrupted() and call it from schedule_debug() when
CONFIG_SCHED_STACK_END_CHECK_is enabled. Fi

Here are some refactorings to prepare for an SVM implementation of
KVM_SET_NESTED_STATE. It's a prerequisite for that to eliminate
exit_required, moving exceptions to svm_check_nested_events. However:

the L1 hypervisor wants to
Split out filling svm->vmcb.save and svm->vmcb.control before VMRUN.
Only the latter will be useful when restoring nested SVM state.

Unmapping the nested VMCB in enter_svm_guest_mode is a bit of a wart,
since the map is not used elsewhere in the function. There are
just two calls, so move it there.

In preparation for nested SVM save/restore, store all data that matters
from the VMCB control area into svm->nested. It will then become part
of the nested SVM state that is saved by KVM_SET_NESTED_STATE and
restored by KVM_GET_NESTED_STATE, just like the cached vmcs12 for nVMX.

Now that the int_ctl field is stored in svm->nested.int_ctl, we can

Hi Linus,
Please pull the following Kselftest update for Linux 5.7-rc6.
This Kselftest update for Linux 5.7-rc6 consists of
- lkdtm runner fixes to prevent dmesg clearing and shellcheck errors
- ftrace test handling when test module doesn't exist
- nsfs test fix to replace zero-length array wit
When restoring SVM nested state, the control state will be stored already
in svm->nested by KVM_SET_NESTED_STATE. We will not need to fish it out of
L1's VMCB. Pull everything into a separate function so that it is
documented which fields are needed.

If DMAC register is left uncleared any further DMAless transfers

So the next DMA-based Rx/Tx transaction will be started right
after the dma_async_issue_pending() method is invoked even if no
DMATDLR/DMARDLR conditions are met. Th

Instead of writing similar event handling code for each ASIC, move the code
to the common firmware file. This code will be used for GAUDI and all
future ASICs.
In addition, add two new fields to the auto-generated events file: valid

Analogously to the introduction of panic_on_warn, this patch introduces a kernel
