[Bug 213481] SMbus ioctls don't transfer the struct smbcmd's rdata back to userland
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213481 Bug ID: 213481 Summary: SMbus ioctls don't transfer the struct smbcmd's rdata back to userland Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: l...@perftech.com Commands that return data in rdata don't work as documented. As an example, SMB_READW is documented as returning the word read from the device in rdata.word. However, this doesn’t happen, because the ioctl request value is defined using _IOW(), so the kernel doesn’t copy the data it read back out. In prior versions, the structure had only a pointer to the data, and the smb.c code used copyout() to transfer the data back to userland. A temporary work-around is to set rbuf to point to rdata.word and rcount to two. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
