[New-bugs-announce] [issue20664] _findLib_crle and _get_soname broken on latest SunOS 5.11

[Ryan Gordon]

New submission from Ryan Gordon:

On SunOS 5.11, both the _findLib_crle and _get_soname are broken.

With _findLib_crle, the function returns the following:

# env LC_ALL=C /usr/bin/crle -64

Default configuration file (/var/ld/64/ld.config) not found
  Platform:     64-bit LSB AMD64
  Default Library Path (ELF):   /lib/64:/usr/lib/64  (system default)
  Trusted Directories (ELF):    /lib/secure/64:/usr/lib/secure/64  (system default)

# env LC_ALL=C /usr/bin/crle

Configuration file [version 4]: /var/ld/ld.config  
  Platform:     32-bit LSB 80386
  Default Library Path (ELF):   /lib:/usr/lib
  Trusted Directories (ELF):    /lib/secure:/usr/lib/secure  (system default)

Command line:
  crle -c /var/ld/ld.config -l /lib:/usr/lib

The "Default Library Path (ELF):   /lib:/usr/lib" is extracted to "/lib:/usr/lib" and only those two paths are checked for the library in question. Unfortunately this means that there is absolutely no way to configure any environment variable to check on other paths and both /lib and /usr/lib are read-only directories mounted from the global zone:

[ /usr/lib] # touch test.txt
touch: cannot touch `test': Read-only file system
[ /lib] # touch test.txt
touch: cannot touch `test': Read-only file system

An environment variable should be read in that can be configured to override this functionality.

The second issue with _get_soname is that is calls /usr/ccs/bin/dump which doesn't exist at all: (/usr/ccs/bin/ is an old deprecated directory which has since been removed)

# ll /usr/ccs/bin/dump
ls: cannot access /usr/ccs/bin/dump: No such file or directory
