Bug ID: 27362
Summary: rtld: Add dtv_surplus tunable for dtv
Product: glibc
Version: 2.34
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: wangxuszcn at foxmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---

Add dtv_surplus tunable for dtv
rtld: Add dtv_surplus tunable for dtv
DTV_SURPLUS is used to avoid in the most cases expansions of dtv,
default is 14, but sometimes it is not big enough. If we have to
expand the size of dtv, the TLS variable is accessed using
_dl_tlsdesc_dynamic(), which is three times lower than
_dl_tlsdesc_return().
This patch add a new tunable, to adjust dtv surplus conveniently.
