The following commit has been merged in the master branch: commit 674d85eb2d7dc6ef436f46f770f7ab3f1b9c6669 Merge: 645c248d6fc4350562766fefd8ba1d7defe4b5e7 1320a4052ea11eb2879eb7361da15a106a780972 Author: Linus Torvalds <torvalds(a)linux-foundation.org> Date: Tue Mar 31 15:04:17 2020 -0700 Merge tag 'audit-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit Pull audit updates from Paul Moore: "We've got two audit patches for the v5.7 merge window with a stellar 14 lines changed between the two patches. The patch descriptions are far more lengthy than the patches themselves, which is a very good thing for patches this size IMHO. The patches pass our test suites and a quick summary is below: - Stop logging inode information when updating an audit file watch. Since we are not changing the inode, or the fact that we are watching the associated file, the inode information is just noise that we can do without. - Fix a problem where mandatory audit records were missing their accompanying audit records (e.g. SYSCALL records were missing). The missing records often meant that we didn't have the necessary context to understand what was going on when the event occurred" * tag 'audit-pr-20200330' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: trigger accompanying records when no rules present audit: CONFIG_CHANGE don't log internal bookkeeping as an event diff --combined kernel/audit.c index 9ddfe2aa6671,b96331e1976d..b69c8b460341 --- a/kernel/audit.c +++ b/kernel/audit.c @@@ -1101,11 -1101,13 +1101,11 @@@ static void audit_log_feature_change(in audit_log_end(ab); } -static int audit_set_feature(struct sk_buff *skb) +static int audit_set_feature(struct audit_features *uaf) { - struct audit_features *uaf; int i; BUILD_BUG_ON(AUDIT_LAST_FEATURE + 1 > ARRAY_SIZE(audit_feature_names)); - uaf = nlmsg_data(nlmsg_hdr(skb)); /* if there is ever a version 2 we should handle that here */ @@@ -1173,7 -1175,6 +1173,7 @@@ static int audit_receive_msg(struct sk_ { u32 seq; void *data; + int data_len; int err; struct audit_buffer *ab; u16 msg_type = nlh->nlmsg_type; @@@ -1187,7 -1188,6 +1187,7 @@@ seq = nlh->nlmsg_seq; data = nlmsg_data(nlh); + data_len = nlmsg_len(nlh); switch (msg_type) { case AUDIT_GET: { @@@ -1211,7 -1211,7 +1211,7 @@@ struct audit_status s; memset(&s, 0, sizeof(s)); /* guard against past and future API changes */ - memcpy(&s, data, min_t(size_t, sizeof(s), nlmsg_len(nlh))); + memcpy(&s, data, min_t(size_t, sizeof(s), data_len)); if (s.mask & AUDIT_STATUS_ENABLED) { err = audit_set_enabled(s.enabled); if (err < 0) @@@ -1315,9 -1315,7 +1315,9 @@@ return err; break; case AUDIT_SET_FEATURE: - err = audit_set_feature(skb); + if (data_len < sizeof(struct audit_features)) + return -EINVAL; + err = audit_set_feature(data); if (err) return err; break; @@@ -1329,8 -1327,6 +1329,8 @@@ err = audit_filter(msg_type, AUDIT_FILTER_USER); if (err == 1) { /* match or error */ + char *str = data; + err = 0; if (msg_type == AUDIT_USER_TTY) { err = tty_audit_push(); @@@ -1338,24 -1334,26 +1338,24 @@@ break; } audit_log_user_recv_msg(&ab, msg_type); - if (msg_type != AUDIT_USER_TTY) + if (msg_type != AUDIT_USER_TTY) { + /* ensure NULL termination */ + str[data_len - 1] = '\0'; audit_log_format(ab, " msg='%.*s'", AUDIT_MESSAGE_TEXT_MAX, - (char *)data); - else { - int size; - + str); + } else { audit_log_format(ab, " data="); - size = nlmsg_len(nlh); - if (size > 0 && - ((unsigned char *)data)[size - 1] == '\0') - size--; - audit_log_n_untrustedstring(ab, data, size); + if (data_len > 0 && str[data_len - 1] == '\0') + data_len--; + audit_log_n_untrustedstring(ab, str, data_len); } audit_log_end(ab); } break; case AUDIT_ADD_RULE: case AUDIT_DEL_RULE: - if (nlmsg_len(nlh) < sizeof(struct audit_rule_data)) + if (data_len < sizeof(struct audit_rule_data)) return -EINVAL; if (audit_enabled == AUDIT_LOCKED) { audit_log_common_recv_msg(audit_context(), &ab, @@@ -1367,7 -1365,7 +1367,7 @@@ audit_log_end(ab); return -EPERM; } - err = audit_rule_change(msg_type, seq, data, nlmsg_len(nlh)); + err = audit_rule_change(msg_type, seq, data, data_len); break; case AUDIT_LIST_RULES: err = audit_list_rules_send(skb, seq); @@@ -1382,7 -1380,7 +1382,7 @@@ case AUDIT_MAKE_EQUIV: { void *bufp = data; u32 sizes[2]; - size_t msglen = nlmsg_len(nlh); + size_t msglen = data_len; char *old, *new; err = -EINVAL; @@@ -1458,7 -1456,7 +1458,7 @@@ memset(&s, 0, sizeof(s)); /* guard against past and future API changes */ - memcpy(&s, data, min_t(size_t, sizeof(s), nlmsg_len(nlh))); + memcpy(&s, data, min_t(size_t, sizeof(s), data_len)); /* check if new data is valid */ if ((s.enabled != 0 && s.enabled != 1) || (s.log_passwd != 0 && s.log_passwd != 1)) @@@ -1800,6 -1798,7 +1800,7 @@@ struct audit_buffer *audit_log_start(st } audit_get_stamp(ab->ctx, &t, &serial); + audit_clear_dummy(ab->ctx); audit_log_format(ab, "audit(%llu.%03lu:%u): ", (unsigned long long)t.tv_sec, t.tv_nsec/1000000, serial); -- LinuxNextTracking

R. Silva. 7) Align XDP statistics names across several drivers for consistency, from Lorenzo Bianconi. 8) Add various pieces of infrastructure for offloading conntrack, and make use of it in mlx5 driver, from Paul Blakey. 9) Allow using listening sockets in BPF sockmap, from Jakub Sitnicki. 10) Lots of parallelization improvements during configuration changes in mlxsw driver, from Ido Schimmel. 11) Add support to devlink for generic packet traps, which report packets dropped during ACL processing. And use them in mlxsw driver. From Jiri Pirko. 12) Support bcmgenet on ACPI, from Jeremy Linton. 13) Make BPF compatible with RT, from Thomas Gleixnet, Alexei Starovoitov, and your's truly. 14) Support XDP meta-data in virtio_net, from Yuya Kusakabe. 15) Fix sysfs permissions when network devices change namespaces, from Christian Brauner. 16) Add a flags element to ethtool_ops so that drivers can more simply indicate which coalescing parameters they actually support, and therefore the generic layer can validate the user's ethtool request. Use this in all drivers, from Jakub Kicinski. 17) Offload FIFO qdisc in mlxsw, from Petr Machata. 18) Support UDP sockets in sockmap, from Lorenz Bauer. 19) Fix stretch ACK bugs in several TCP congestion control modules, from Pengcheng Yang. 20) Support virtual functiosn in octeontx2 driver, from Tomasz Duszynski. 21) Add region operations for devlink and use it in ice driver to dump NVM contents, from Jacob Keller. 22) Add support for hw offload of MACSEC, from Antoine Tenart. 23) Add support for BPF programs that can be attached to LSM hooks, from KP Singh. 24) Support for multiple paths, path managers, and counters in MPTCP. From Peter Krystad, Paolo Abeni, Florian Westphal, Davide Caratti, and others. 25) More progress on adding the netlink interface to ethtool, from Michal Kubecek" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2121 commits) net: ipv6: rpl_iptunnel: Fix potential memory leak in rpl_do_srh_inline cxgb4/chcr: nic-tls stats in ethtool net: dsa: fix oops while probing Marvell DSA switches net/bpfilter: remove superfluous testing message net: macb: Fix handling of fixed-link node net: dsa: ksz: Select KSZ protocol tag netdevsim: dev: Fix memory leak in nsim_dev_take_snapshot_write net: stmmac: add EHL 2.5Gbps PCI info and PCI ID net: stmmac: add EHL PSE0 & PSE1 1Gbps PCI info and PCI ID net: stmmac: create dwmac-intel.c to contain all Intel platform net: dsa: bcm_sf2: Support specifying VLAN tag egress rule net: dsa: bcm_sf2: Add support for matching VLAN TCI net: dsa: bcm_sf2: Move writing of CFP_DATA(5) into slicing functions net: dsa: bcm_sf2: Check earlier for FLOW_EXT and FLOW_MAC_EXT net: dsa: bcm_sf2: Disable learning for ASP port net: dsa: b53: Deny enslaving port 7 for 7278 into a bridge net: dsa: b53: Prevent tagged VLAN on port 7 for 7278 net: dsa: b53: Restore VLAN entries upon (re)configuration net: dsa: bcm_sf2: Fix overflow checks hv_netvsc: Remove unnecessary round_up for recv_completion_cnt ... diff --combined MAINTAINERS index a2b9bbf6e8b2,e3e2db696ae9..195052943574 --- a/MAINTAINERS +++ b/MAINTAINERS @@@ -176,7 -176,7 +176,7 @@@ L: linux-wpan(a)vger.kernel.or S: Maintained F: net/6lowpan/ F: include/net/6lowpan.h -
