From: Francis Laniel <laniel_fran...@privacyrequired.com> Hi.
I hope you are all fine and the same for your relatives. This patch set answers to first three issues listed in: https://github.com/KSPP/linux/issues/110 To sum up, the patch contributions are the following: 1. the first patch fixes an inefficiency where some bytes in dst were written twice, one with 0 the other with src content. 2. The second one modifies nla_strlcpy to return the same value as strscpy, i.e. number of bytes written or -E2BIG if src was truncated. It also modifies code that calls nla_strlcpy and checks for its return value. 3. The third renames nla_strlcpy to nla_strscpy. Unfortunately, I did not find how to create struct nlattr objects so I tested my modifications on simple char* and with GDB using tc to get to tcf_proto_check_kind. If you see any way to improve the code or have any remark, feel free to comment. Best regards and take care of yourselves. Francis Laniel (3): Fix unefficient call to memset before memcpu in nla_strlcpy. Modify return value of nla_strlcpy to match that of strscpy. treewide: rename nla_strlcpy to nla_strscpy. drivers/infiniband/core/nldev.c | 10 +++--- drivers/net/can/vxcan.c | 4 +-- drivers/net/veth.c | 4 +-- include/linux/genl_magic_struct.h | 2 +- include/net/netlink.h | 4 +-- include/net/pkt_cls.h | 2 +- kernel/taskstats.c | 2 +- lib/nlattr.c | 42 ++++++++++++++-------- net/core/fib_rules.c | 4 +-- net/core/rtnetlink.c | 12 +++---- net/decnet/dn_dev.c | 2 +- net/ieee802154/nl-mac.c | 2 +- net/ipv4/devinet.c | 2 +- net/ipv4/fib_semantics.c | 2 +- net/ipv4/metrics.c | 2 +- net/netfilter/ipset/ip_set_hash_netiface.c | 4 +-- net/netfilter/nf_tables_api.c | 6 ++-- net/netfilter/nfnetlink_acct.c | 2 +- net/netfilter/nfnetlink_cthelper.c | 4 +-- net/netfilter/nft_ct.c | 2 +- net/netfilter/nft_log.c | 2 +- net/netlabel/netlabel_mgmt.c | 2 +- net/nfc/netlink.c | 2 +- net/sched/act_api.c | 2 +- net/sched/act_ipt.c | 2 +- net/sched/act_simple.c | 4 +-- net/sched/cls_api.c | 2 +- net/sched/sch_api.c | 2 +- net/tipc/netlink_compat.c | 2 +- 29 files changed, 73 insertions(+), 61 deletions(-) -- 2.20.1
