Code reading questions

###1. What happens (in broad terms) if sys_remove is called on a file that is currently open by another running process? Will a read on the file by the second process succeed? A write? Why or why not? (1 point)

sys_remove removes the inode of the file from the file system. The processes that have a reference to the file will retain that reference and will be able to call read/write on that file and succeed. Processes trying to open the flie after sys_remove will not be allowed to do so. The file is purges from the filesystem after all open file descriptors fo that file have been closed.

###2. Describe the control flow, starting in the system call layer and proceeding through the VFS layer to reach SFS, that occurs for each of the following system calls. You need only trace the names of the functions that are called. Feel free to skip secondary or minor code paths that don't lead into SFS. (1 point)

###3. Now similarly describe the control flow within SFS for each of the same oper

Sample Apache's mod_security rules for rate-limiting
# Activates mod_security
SecRuleEngine On
# Only filters requests for /toto
SecRule REQUEST_FILENAME "!^/toto" "phase:1,skip:5,nolog"
# Only filters requests for rosalind
SecRule REQUEST_HEADERS:Host "rosalind\.abgenomica\.com" "phase:1,skip:5,nolog"
# Stores the number of visits in variable IP.pagecount
SecAction "phase:1,nolog,initcol:IP=%{REMOTE_ADDR},setvar:IP.pagecount=+1,expirevar:IP.pagecount=60"
# Denies requests when excessive
# 429 would be a better error status but mod_security rewrites it as 500 :-(

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
