Subject: [PATCH v4 19/34] xsplice, symbols: Implement symbol name resolution on address.
Date: Tue, 15 Mar 2016 13:56:41 -0400 [thread overview]
Message-ID: <1458064616-23101-20-git-send-email-konrad.wilk@oracle.com> (raw)
In-Reply-To: <1458064616-23101-1-git-send-email-konrad.wilk@oracle.com>
If in the payload we do not have the old_addr we can resolve
the virtual address based on the UNDEFined symbols.
We also use an boolean flag: new_symbol to track symbols. The usual
case this is used is by:
* A payload may introduce a new symbol
* A payload may override an existing symbol (introduced in Xen or another
payload)
* Overriding symbols must exist in the symtab for backtraces.
* A payload must always link against the object which defines the new symbol.
Considering that payloads may be loaded in any order it would be incorrect to
link against a payload which simply overrides a symbol because you could end
up with a chain of jumps which is inefficient and may result in the expected
function not being executed.
Also we include a local definition block in the symbols.c file.
