Bug ID: 235867
Summary: libmap
Product: Base System
Version: 11.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: conf
Assignee: b...@freebsd.org
Reporter: o...@pcbtech.ru
libmap.conf's /path1 to /path2 replacement doesn't work
e.g.:
$ uname -a
FreeBSD xx.yy.ru 11.2-RELEASE-p9 FreeBSD 11.2-RELEASE-p9 #0 r344133: Thu Feb 14
23:36:20 MSK 2019 x...@yy.zz.ru:/usr/obj/usr/src/sys/GENERIC amd64
$ cat /etc/libmap.conf
# $FreeBSD: releng/11.2/etc/libmap.conf 253853 2013-08-01 05:50:42Z jlh $
includedir /usr/local/etc/libmap.d
$ cat /usr/local/etc/libmap.d/error.conf
[/usr/sbin/pmcstat]
/lib /usr/local/php56libz
$ ldd /usr/sbin/pmcstat
/usr/sbin/pmcstat:
libelf.so.2 => /lib/libelf.so.2 (0x800833000)
libkvm.so.7 => /lib/libkvm.so.7 (0x800a4a000)
libpmc.so.5 => /usr/lib/libpmc.so.5 (0x800c58000)
libm.so.5 => /lib/libm.so.5 (0x800eff000)
libncursesw.so.8 => /lib/libncursesw.so.8 (0x80112c000)
libc.so.7 => /lib/libc.so.7 (0x80138b000)
let's add a line with direct lib substitution:
$ cat /usr/local/etc/libmap.d/error.conf
[/usr/sbin/pmcstat]
/lib /usr/local/php56libz
libm.so.5 /usr/local/php56libz/libm.so.5
$ ldd /usr/sbin/pmcstat
/usr/sbin/pmcstat:
libelf.so.2 => /lib/libelf.so.2 (0x800833000)
libkvm.so.7 => /lib/libkvm.so.7 (0x800a4a000)
libpmc.so.5 => /usr/lib/libpmc.so.5 (0x800c58000)
libm.so.5 => /usr/local/php56libz/libm.so.5 (0x800eff000)
libncursesw.so.8 => /lib/libncursesw.so.8 (0x80112c000)
libc.so.7 => /lib/libc.so.7 (0x80138b000)
that works. Definition of LD_LIBMAP also works:
$ env LD_LIBMAP="/lib /usr/local/php56libz" ldd /usr/sbin/pmcstat
/usr/sbin/pmcstat:
libelf.so.2 => not found (0)
libkvm.so.7 => not found (0)
libpmc.so.5 => /usr/lib/libpmc.so.5 (0x800833000)
libm.so.5 => /usr/local/php56libz/libm.so.5 (0x800ada000)
libncursesw.so.8 => not found (0)
libc.so.7 => /usr/local/php56libz/libc.so.7 (0x800d07000)
So, I suppose that the bug occurs while trying to override /path1 to /path2
within libmap.conf subsystem.
