When running on multiple hosts with output coalesced, it is useful to
be able to isolate messages from individual processes. This patch adds
the ability to add the string "[hostname:pid] " to all messages emitted
by libhugetlbfs. Display this additional information by setting the
environment vari
With all of the dependencies on custom linker scripts removed, introduce a
segment remapping algorithm that is compatible with the system linker scripts
(binutils 2.18 or later).
The only thing that is strictly required for full segment remapping to be
possible is a large enough gap between the te
With the core of libhugetlbfs now supporting relinking without the need for
custom scripts, export the feature to users in an easy to use manner. For a
binary to be properly linked to support this remapping method, three things
must be added to the ld command line during the final link:
-zcommon-p
The segment parsing code for binaries linked with custom linker scripts is now
nearly identical to the new system script method so we can consolidate two
functions into one code path.
There are two interesting semantics to note:
1) verify_segment_layout() will be called when we are using custom li
The current remapping algortithm assumes that each PT_LOAD elf segment has a
starting address (vaddr) that is aligned to the huge page size. This
condition was enforced by the custom linker scripts that are packaged with
libhugetlbfs.
Unaligned starting addresses can be corrected simply by aligni
The current implementation of libhugetlbfs segment remapping requires that a
binary be linked with a custom linker script that is included in the library
distribution. Over time these custom linker scripts have needed updating to
keep them compatible with changes occuring in binutils. While we've
