Subject: [PATCH v5 00/11] eal: replace calls to rte_panic and refrain from new instances
Date: Tue, 24 Apr 2018 00:28:51 +0300 [thread overview]
Message-ID: <1524518942-1998-1-git-send-email-arnon@qwilt.com> (raw)
The purpose of this patch series is to cleanup the library code
from paths that end up aborting the process,
and move to checking error values, in order to allow the running process
perform an orderly teardown or other mitigation of the event.
This patch modifies the majority of rte_panic calls
under lib and drivers, and replaces them with a log message
and an error return code according to context,
that can be propagated up the call stack.
- Focus was given to the dpdk initialization path
- Some of the panic calls within drivers were left in place where
the call is from within an interrupt or calls that are
on the data path,where there is no simple applicative
route to propagate the error to temination.
These should be handled by the driver maintainers..
- local void functions with no api were changed to retrun a value
where needed
- No change took place in example and test files
- No change took place for debug assertions calling panic
- A new function was added to devtools/checkpatches.sh
in order to prevent new additions of calls to rte_panic
under lib and drivers.
Keep calm and don't panic
---
v2:
- reformat error messages so that literal string are in the same line
- fix typo in commit message
- add new return code to doxigen of rte_memzone_free()
v3:
- submit all 13 patches changed and unchanged in the same patchset
v4:
- remove 2 patches that are no more relevant
- fix split literal string in error message
- change return value -1 to enum
- split value and success code in a static function
v5:
- reword commit messages
- revert thread related instances back to panicing
- handle file descriptors with state to reset after eal init failure
in case re initialization takes place
