Summary: blacklist is too broad (raw_.*)
Product: systemtap
Version: unspecified
Status: NEW
Severity: minor
Priority: P2
Component: translator
AssignedTo: systemtap@sourceware.org
ReportedBy: adrien@kunysz.be
As reported by dpward on IRC, some functions that have no obvious reason to be
blacklisted are "hidden" by the "raw_.*" regular expression. Most notably, the
raw_sendmsg@net/ipv4/raw.c function is not accessible outside of guru mode. A
quick grep of /proc/kallsyms shows other possible casualties, the most obvious
ones being in the following files:
drivers/char/raw.c
net/ieee802154/raw.c
net/ipv4/raw.c
net/can/raw.c
The "raw_.*" filter seems to be targeted at locks but it doesn't specify which
ones so how to fix this properly isn't immediately obvious (to me).
