Branch: sys/kern RELENG_2_2
Modified: sys/kern kern_exec.c
Log:
Fixed two bugs that came into kern_exec just after the 2.2.1 release:
1) I wasn't assuring that the file size was large enough for the data
to be contained in a FS block. Calling bread for a block when the
data is in a fragment causes BAD things to happen, including file
corruption.
2) I was not passing in a residual pointer to vn_rdwr(), and this
caused "slow" mode image header reads that were less than the
page size to fail with EIO. I now get the residual and properly
zero the tail of the image header buffer, too.
