Without this change it segfaults when trying to play any media: $ jellyfinmediaplayer Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome.

Previously, hashcat was unable to use CUDA at runtime, and would warn: > Failed to initialize the NVIDIA main driver CUDA runtime library. > Failed to initialize NVIDIA RTC library. > * Device #1: CUDA SDK Toolkit not installed or incorrectly installed. > CUDA SDK Toolkit required for proper device support and utilization. > Falling back to OpenCL runtime. This remedies that, at least on NixOS.

1.2.1: Bug fix release: Single bug fix (#1) that fixes regression in `perf` tool caused by libbpf resetting its custom catch-all `SEC()` handler on explicit `bpf_program__set_type()` call. Given setting custom `SEC()` handlers is rarely used and pretty esoteric feature of libbpf, most users should not be affected. 1.2.2: One more fix: - Fix (#2) possible double-free in USDT-related libbpf code, which happens when libbpf runs out of space in `__bpf_usdt_specs` map due to having too many unique USDT specs. Running out of space can be mitigated by bumping up `BPF_USDT_MAX_SPEC_CNT` define before including `bpf/usdt.bpf.h` header in BPF-side code. This will prevent the double-free as a side effect (and will make it possible to successfully attach all requested USDTs), which is a recommended work-around for libbpf versions prior to v1.2.2. Link: libbpf/libbpf@e4d3827 #1 Link: libbpf/libbpf@f117080 #2
