First draft of changes to fix format overflow issues in EAL and related libraries. This does introduce more restrictions on file prefix and some parameters because of more checking for overflow.
Stephen Hemminger (14): eal: use C library to parse filesystem table test: avoid long hash names lpm: restrict name size hash: avoid possible ring name overflow graph: avoid overflowing comment buffer eal: warn if thread name is truncated eal: avoid format overflow when handling addresses ethdev: avoid possible overflow in xstat names vhost: check for overflow in xstat name efd: avoid overflowing ring name eal: add check for sysfs path overflow eal: limit maximum runtime directory and socket paths eal: check for hugefile path overflow lib: enable format overflow warnings app/test/test_hash.c | 29 +++++++---- lib/eal/common/eal_common_config.c | 6 ++- lib/eal/common/eal_common_memory.c | 2 +- lib/eal/common/eal_common_proc.c | 83 +++++++++++++++++++----------- lib/eal/common/eal_filesystem.h | 16 ++++-- lib/eal/linux/eal.c | 6 ++- lib/eal/linux/eal_hugepage_info.c | 64 +++++++++-------------- lib/eal/linux/eal_memalloc.c | 11 +++- lib/eal/linux/eal_memory.c | 9 +++- lib/efd/rte_efd.c | 15 +++++- lib/ethdev/rte_ethdev.c | 28 +++++++--- lib/graph/graph_pcap.c | 9 ++-- lib/hash/rte_cuckoo_hash.c | 21 +++++--- lib/hash/rte_hash.h | 6 ++- lib/lpm/rte_lpm.h | 2 +- lib/meson.build | 4 -- lib/vhost/vhost.c | 14 +++-- 17 files changed, 202 insertions(+), 123 deletions(-) -- 2.51.0
