#
# The following suppressions are suited for debug build
# of librpma on Ubuntu 22.04 used in the CircleCI.
# They may not work for any other OS, OS version,
# rdma-core version and for the release build.
#
#
# All suppressions should follow the following format:
#
# Assessment: (XXX - to mark assessment that is not done yet)
#
# This suppression indicates a lack of MT safety.
#
# OS: a version of OS
# OFED: a version of OFED if used
# libibverbs: a version of libibverbs
# librdmacm: a version of librdmacm
# rdma-core: a version of the 'rdma-core' package if installed
#
# Occurs in traces of:
# - a function name of public API of librpma
#
# There are 3 types of suppressions:
#
# 1) general one (on an external API)
# {
# Possible data race during write of size 4
# Helgrind:Race
# ...
# fun:ibv_dontfork_range
# ...
# }
#
# 2) explicit librpma API call
# {
# Possible data race during write of size 4
# Helgrind:Race
# ...
# fun:rpma_conn_cfg_set_timeout
# ...
# }
#
# 3) detailed external one (on an external API)
# {
# Possible data race during write of size 4
# Helgrind:Race
# ...
# fun:funA
# fun:funB
# fun:funC
# fun:function_call_used directly form_public_API
# ...
# }
#
#
# Assessment: this suppression indicates a lack of MT safety.
#
# syslog(3) has the "MT-Safe env locale" attributes(7)
# and therefore it can be considered as not MT-safe by valgrind.
# This issue can cause that logs of syslog(3) can be corrupted,
# but it does not affect the MT-safety of the librpma library.
#
# OS: ubuntu-2204:2022.04.1 of CircleCI
# libibverbs: 1.14.39.0
# librdmacm: 1.3.39.0
#
# It can occur in traces of all functions of librpma API.
