* build: Remove configure check for MADV_DONTDUMPDaiki Ueno2019-05-151-1/+1
| | | | It can be checked in the source code instead.
* egg: Request that secure memory not be dumped to diskMatthew Garrett2019-04-201-0/+13
| | | | | | | | | | Linux 3.4 added support for the MADV_DONTDUMP option to madvise(), which requests that the covered memory not be included in coredumps. It makes sense to use this to prevent cases where application crashes could result in secrets being persisted to disk or included in dumps that are uploaded to remote servers for analysis. I've avoided making this fatal since there's a chance this code could be built on systems that have MADV_DONTDUMP but run on systems that don't.

* egg: Fix null termination behavior of egg_secure_strndup()Daiki Ueno2018-02-211-0/+1
| | | | | Even if the given string is shorter than n, the result should be null terminated. This matches the behavior of strndup().

| * [egg] Fix assertion when releasing secure memory block.Stef Walter2009-09-301-1/+1
| | | | | | | | | | | | | | If a secure memory block was allocated that was not multiple of page size, then on releasing that block, an assertion was raised. The source of the problem was a lack of tracking the actually allocated block size.
