Subject: [PATCH v4] Livepatch fixes and features for v4.8.
Date: Tue, 23 Aug 2016 22:22:03 -0400 [thread overview]
Message-ID: <1472005332-32207-1-git-send-email-konrad.wilk@oracle.com> (raw)
Hey!
Since v3: [https://lists.xen.org/archives/html/xen-devel/2016-08/msg01825.html]
- Acked on reviews
v2, v1:
- Left over fixes and features that didn't get quite done in 4.7
Included are:
- Bug-fixes
- Parsing of symbol names encoded as: symbol+0x<offset>
- NOP patching
- Generating an symbol map file with Xen's unique symbols (file#symbol)
so tools generating livepatch payloads can verify the right names.
- Hooks
The 'hooks' are the most controversial part of this and are left as the
last patch :-)
The legend is:
r - Reviewed
[PATCH v4 1/9] livepatch: Clear .bss when payload is reverted
rr [PATCH v4 2/9] livepatch: Deal with payloads without any .text
rr [PATCH v4 3/9] version/livepatch: Move xen_build_id_check to
[PATCH v4 4/9] version: Print build-id at bootup.
[PATCH v4 5/9] livepatch: Move code from prepare_payload to own
[PATCH v4 6/9] livepatch: Add parsing for the symbol+0x<offset>
[PATCH v4 7/9] livepatch: NOP if func->new_[addr] is zero.
[PATCH v4 8/9] symbols: Generate an xen-sym.map
[PATCH v4 9/9] livepach: Add .livepatch.hooks functions and test-case
so one can ignore #2 and #3.
Thanks!
