Bug ID: 23474
Summary: bpf kernel_string(), user_string() tapset
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: bpf
Assignee: systemtap at sourceware dot org
Reporter: me at serhei dot io
Target Milestone: ---
From the 'language features' brainstorm:
# Loading kernel_string(addr) or user_string(addr) onto the stack
offset = 80
unrolled loop {
*(u64 *)(r10-offset) = *(u64 *)addr
addr += 8; offset -= 8
} until '\0' encountered or BPF_MAXSTRINGLEN bytes copied
/* loading kernel_string(addr) or user_string(addr) into an eBPF map is similar
*/
