Hi,
I have tagged the e-mail with 4.15 as I think we likely want some of the
patches to be in the next release.
As a minimum, we get the following:
- patch #7: xenstore: handle do_mkdir and do_rm failure
- patch #8: xenstore: add missing NULL check
- patch #10: xs: add error handling
The first two add missing NULL check in runtime code in XenStored. The
3rd one adds a missing NULL check in xs_is_domain_introduced() in
libxenstore (can be used at runtime by xenpaging at least).
In addition to that, I would like to consider patch #3: xenstore: check
formats of trace. It is allowing the compiler to check the format printf
for trace(). This should be low-risk.
For the rest is a mix of silencing coverity and potential errors either
at init or in a standalone binaries.
The init ones would be useful (patch #1, #5, #9) for Xenstored
LiveUpdate as they would be potential triggered when upgrading the
binary. But I am not sure whether we consider LiveUpdate supported.
Any thoughts?
Cheers,

Dear all,
we have been running some code analysis tools on the xenstore code, and triaged
the results. This series presents the robustness fixes we identified.
Best,
