commit 3d0220f6861d713213b015b582e9f21e5b28d2e0 upstream.
Add a container structure struct bpf_sanitize_info which holds the current aux info, and update call-sites to sanitize_ptr_alu() to pass it in. This is needed for passing in additional state later on.

commit bb01a1bba579b4b1c5566af24d95f1767859771e upstream.
Masking direction as indicated via mask_to_left is considered to be calculated once and then used to derive pointer limits. Thus, this needs to be placed into bpf_sanitize_info instead so we can pass it to sanitize_ptr_alu() call after the pointer move. Piotr noticed a corner case where the off reg causes masking direction change which then results in an incorrect final aux->alu_limit.

commit a7036191277f9fa68d92f2071ddc38c09b1e5ee5 upstream.
In 801c6058d14a ("bpf: Fix leakage of uninitialized bpf stack under speculation") we replaced masking logic with direct loads of immediates if the register is a known constant. Given in this case we do not apply any masking, there is also no reason for the operation to be truncated under the speculative domain.
Therefore, there is also zero reason for the verifier to branch-off and simulate this case, it only needs to do it for unknown but bounded scalars. As a side-effect, this also enables few test cases that were previously rejected due to simulation under zero truncation.

commit d1d90dd27254c44d087ad3f8b5b3e4fff0571f45 upstream.
commit 72704f876f50 ("dwc3: gadget: Implement the suspend entry event handler") introduced (nearly 5 years ago!) an interrupt handler for U3/L1-L2 suspend events. The problem is that these events aren't currently enabled in the DEVTEN register so the handler is never even invoked. Fix this simply by enabling the corresponding bit in dwc3_gadget_enable_irq() using the same revision check as found in the handler.

commit bf53fc6b5f415cddc7118091cb8fd6a211b2320d upstream.
elfutils needs to be provided main binary and separate debug info file respectively. Providing separate debug info file instead of the main binary is not sufficient.
One needs to try both supplied filename and its possible cache by its build-id depending on the use case.

commit 4e1481445407b86a483616c4542ffdc810efb680 upstream.
When locating the DWARF module for a given address, __find_debuginfo() requires a 'struct dso' passed via the userdata argument.
However, this field is only set in __report_module() if the module is found in via dwfl_addrmodule(), not if it is found later via dwfl_report_elf().
Set userdata irrespective of how the DWARF module was found, as long as we found a module.
