--- Begin Message ---Package: src:linux Version: 5.9.1-1 Severity: minor Dear Maintainer, The sunrpc.transports sysctl looks emtpy when directly queried with sysctl, but a closer inspection of /proc/sys/sunrpc/transports reveals a list of null bytes. Even weirder, sysctl -a does produce a different set of random(?) characters each time. I would expect an output such as: sunrpc.transports = tcp 1048576 sunrpc.transports = udp 32768 instead of this weirdness. $ /sbin/sysctl sunrpc.transports | cat -A ; od -c /proc/sys/sunrpc/transports ; /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports sunrpc.transports = $ 0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000020 \0 \0 \0 \0 \0 \0 0000026 sunrpc.transports = �]� $ /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports sunrpc.transports = �� $ /sbin/sysctl -a 2>/dev/null | grep -a sunrpc.transports sunrpc.transports = �vo� Last week I updated this system to Debian testing (from stable). -- Package-specific info: ** Version: Linux version 5.9.0-1-amd64 ([email protected]) (gcc-10 (Debian 10.2.0-15) 10.2.0, GNU ld (GNU Binutils for Debian) 2.35.1) #1 SMP Debian 5.9.1-1 (2020-10-17) ** Command line: BOOT_IMAGE=/vmlinuz-5.9.0-1-amd64 root=/dev/mapper/gallumbits--vg-root ro security=selinux selinux=1 enforcing=0 quiet splash ** Not tainted ** Kernel log: [106119.880235] wlp3s0: associate with 10:8c:cf:45:c8:30 (try 1/3) [106119.882096] wlp3s0: RX AssocResp from 10:8c:cf:45:c8:30 (capab=0x431 status=0 aid=4) [106119.883865] wlp3s0: associated [106119.985055] wlp3s0: Limiting TX power to 17 dBm as advertised by 10:8c:cf:45:c8:30 [107923.048112] Rekeying PTK for STA 10:8c:cf:45:c8:30 but driver can't safely do that.
