Package: libfuse3 Version: 3.14.0-4 Severity: normal Dear Maintainer,
Since bookworm, $ /usr/sbin/febug /run/user/1000/febug/ Ignoring invalid max threads value 4294967295 > max (100000). ... and according to fuse_cmdline_help(): " -o max_idle_threads the maximum number of idle worker threads\n" " allowed (default: -1)\n" fuse_main_real(): if (opts.singlethread) res = fuse_loop(fuse); else { loop_config = fuse_loop_cfg_create(); if (loop_config == NULL) { res = 7; goto out3; } fuse_loop_cfg_set_clone_fd(loop_config, opts.clone_fd); fuse_loop_cfg_set_idle_threads(loop_config, opts.max_idle_threads); fuse_loop_cfg_set_max_threads(loop_config, opts.max_threads); res = fuse_loop_mt(fuse, loop_config); } (and I can confirm it goes away with -s or -omax_idle_threads=10). fuse_loop_cfg_set_idle_threads(): void fuse_loop_cfg_set_idle_threads(struct fuse_loop_config *config, unsigned int value) { if (value > FUSE_LOOP_MT_MAX_THREADS) { fuse_log(FUSE_LOG_ERR, "Ignoring invalid max threads value " "%u > max (%u).\n", value, FUSE_LOOP_MT_MAX_THREADS); return; } config->max_idle_threads = value; } however, there are two separate defaults (one as the argument, and one in fuse_loop_mt.c), and fuse_loop_mt.c:#define FUSE_LOOP_MT_DEF_IDLE_THREADS -1 /* thread destruction is disabled fuse_loop_mt.c: config->max_idle_threads = FUSE_LOOP_MT_DEF_IDLE_THREADS; so -1 is valid by default if unset, defaults to being passed as -1, and is illegal there. Please make the condition (value > FUSE_LOOP_MT_MAX_THREADS && value != FUSE_LOOP_MT_DEF_IDLE_THREADS) Best, наб -- System Information: Debian Release: 12.0 APT prefers stable-security APT policy: (500, 'stable-security'), (500, 'stable-debug'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-9-amd64 (SMP w/24 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_FIRMWARE_WORKAROUND, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages fuse3 depends on: ii adduser 3.134 ii libc6 2.36-9 ii libfuse3-3 3.14.0-4 ii mount 2.38.1-5+b1 ii sed 4.9-1 fuse3 recommends no packages. fuse3 suggests no packages. -- Configuration Files: /etc/fuse.conf changed: user_allow_other -- no debconf information
