Bug ID: 30583
Summary: RFE: Export all IFUNCs as @GLIBC_PRIVATE symbols to
support overrides via audtior (LD_AUDIT)
Product: glibc
Version: 2.38
Status: NEW
Severity: enhancement
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: carlos at redhat dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
We should make it easy for users to experiement with the different
implementations of IFUNCs.
One way to do this is to use GLIBC_TUNABLES, but this is often crude and
applies to all IFUNCs, not just one.
What we should really do is export all IFUNCs as @GLIBC_PRIVATE symbols to
allow a user-written audit module (LD_AUDIT) to select a specific IFUNC during
binding.

It doesn't have to be an auditor, by the way, LD_PRELOAD would work itself. Having GLIBC_PRIVATE symbols would also allow us to print descriptive implementation names during IFUNC resolution. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
