Mine: openat(AT_FDCWD, "/dev/ipmi0", O_RDWR) = 3 <0.000052 Yours: openat(AT_FDCWD, "/dev/ipmi0", O_RDWR) = -1 EINVAL (Invalid argument) <0.000053>
So we are back at the kernel backend of this - on your particular hardware/firmware - not behaving correctly. This isn't one of the later ioctls, just the basic open fails. I re-checked my system and even a "cat /dev/ipmi0" while failing as expected eventually can open the device just fine (only fails later when reading) # strace -e openat cat /dev/ipmi0 2>&1|grep ipmi0 openat(AT_FDCWD, "/dev/ipmi0", O_RDONLY) = 3 So why isn't it "openable" in his case? @Kernel people, what would you want Ventsislav to look out for ? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1836701 Title: ubuntu18.04: ipmitool failed: Could not open device at /dev/ipmi0 : No such file or directory Status in ipmitool package in Ubuntu: Opinion Status in linux package in Ubuntu: Incomplete Bug description: ipmitool failed in-band #ipmitool lan print Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory And it work out-band: # ipmitool -H {theip} -I lanplus -U {user} -P {passwd} lan print Set in Progress : Set Complete Auth Type Support : NONE MD2 MD5 PASSWORD Auth Type Enable : Callback : MD2 MD5 PASSWORD : User : MD2 MD5 PASSWORD : Operator : MD2 MD5 PASSWORD : Admin : MD2 MD5 PASSWORD : OEM : MD2 MD5 PASSWORD IP Address Source : DHCP Address ...
