Alexandar Potapenko while testing the kernel with KMSAN and syzkaller discovered that in some configurations sctp would leak 4 bytes of kernel stack. Working with his reproducer I discovered that those 4 bytes that are leaked is the scope id of an ipv6 address returned by recvmsg. With a little code inspection and a shrewd guess I discovered that sctp_inet6_skb_msgname only initializes the scope_id field for link local ipv6 addresses to the interface index the link local address pertains to instead of initializing the scope_id field for all ipv6 addresses. That is almost reasonable as scope_id's are meaniningful only for link local addresses. Set the scope_id in all other cases to 0 which is not a valid interface index to make it clear there is nothing useful in the scope_id field. There should be no danger of breaking userspace as the stack leak guaranteed that previously meaningless random data was being returned. Fixes: 372f525b ("SCTP: Resync with LKSCTP tree.")

Jon Maloy authored
The socket level flow control is based on the assumption that incoming buffers meet the condition (skb->truesize / roundup(skb->len) <= 4), where the latter value is rounded off upwards to the nearest 1k number. This does empirically hold true for the device drivers we know, but we cannot trust that it will always be so, e.g., in a system with jumbo frames and very small packets. We now introduce a check for this condition at packet arrival, and if we find it to be false, we copy the packet to a new, smaller buffer, where the condition will be true. We expect this to affect only a small fraction of all incoming packets, if at all.

Now CPSW driver configures min eth packet size to 60 octets (ETH_ZLEN) which works in most of cases, but when port VLAN is configured on some switch port, it also can be configured to force all egress packets to be VLAN untagged. And in this case, CPSW driver will pad small packets to 60 octets, but final packet size on port egress can became less than 60 octets due to VLAN tag removal and packet will be dropped. Hence, fix it by accounting VLAN header in CPSW min eth packet size. While here, use proper defines for CPSW_MAX_PACKET_SIZE also, instead of open coding.

The IPv6 Segment Routing Header (SRH) format has been updated (revision 6 of the SRH ietf draft). The update includes the following SRH fields: (1) The "First Segment" field changed to be "Last Entry" which contains the index, in the Segment List, of the last element of the Segment List. (2) The 16 bit "reserved" field now is used as a "tag" which tags a packet as part of a class or group of packets, e.g.,packets sharing the same set of properties. This patch updates the struct ipv6_sr_hdr, so it complies with the updated SRH draft. The 16 bit "reserved" field is changed to be "tag", In addition a comment is added to the "first_segment" field, showing that it represents the "Last Entry" field of the SRH.

rndis_filter_device_add() is called both from netvsc_probe() when we initially create the device and from set channels/mtu/ringparam routines where we basically remove the device and add it back. hw_features is reset in rndis_filter_device_add() and filled with host data. However, we lose all additional flags which are set outside of the driver, e.g. register_netdevice() adds NETIF_F_SOFT_FEATURES and many others. Unfortunately, calls to rndis_{query_hwcaps(), _set_offload_params()} calls cannot be avoided on every RNDIS reset: host expects us to set required features explicitly. Moreover, in theory hardware capabilities can change and we need to reflect the change in hw_features. Reset net->hw_features bits according to host data in rndis_netdev_set_hwcaps(), clear corresponding feature bits from net->features in case some features went missing (will never happen in real life I guess but let's be consistent).

According to the description, first argument of genlmsg_nlhdr() points to what genlmsg_put() returns, i.e. beginning of user header. Therefore we should only subtract size of genetlink header and netlink message header, not user header. This also means we don't need to pass the pointer to genetlink family and the same is true for genl_dump_check_consistent() which is the only caller of genlmsg_nlhdr(). (Note that at the moment, these functions are only used for families which do not have user header so that they are not affected.)

Now when resetting stream, if both in and out flags are set, the info len can reach: sizeof(struct sctp_strreset_outreq) + SCTP_MAX_STREAM(65535) + sizeof(struct sctp_strreset_inreq) + SCTP_MAX_STREAM(65535) even without duplicated stream no, this value is far greater than the chunk's max size. _sctp_make_chunk doesn't do any check for this, which would cause the skb it allocs is huge, syzbot even reported a crash due to this. This patch is to check stream reset info len before making reconf chunk and return EINVAL if the len exceeds chunk's capacity. Thanks Marcelo and Neil for making this clear. v1->v2: - move the check into sctp_send_reset_streams instead.

Commit dfcb9f4f ("sctp: deny peeloff operation on asocs with threads sleeping on it") fixed the race between peeloff and wait sndbuf by checking waitqueue_active(&asoc->wait) in sctp_do_peeloff(). But it actually doesn't work, as even if waitqueue_active returns false the waiting sndbuf thread may still not yet hold sk lock. After asoc is peeled off, sk is not asoc->base.sk any more, then to hold the old sk lock couldn't make assoc safe to access. This patch is to fix this by changing to hold the new sk lock if sk is not asoc->base.sk, meanwhile, also set the sk in sctp_sendmsg with the new sk. With this fix, there is no more race between peeloff and waitbuf, the check 'waitqueue_active' in sctp_do_peeloff can be removed. Thanks Marcelo and Neil for making this clear. v1->v2: fix it by changing to lock the new sock instead of adding a flag in asoc.

Now in sctp_sendmsg sctp_wait_for_sndbuf could schedule out without holding sock sk. It means the current asoc can be freed elsewhere, like when receiving an abort packet. If the asoc is just created in sctp_sendmsg and sctp_wait_for_sndbuf returns err, the asoc will be freed again due to new_asoc is not nil. An use-after-free issue would be triggered by this. This patch is to fix it by setting new_asoc with nil if the asoc is already dead when cpu schedules back, so that it will not be freed again in sctp_sendmsg. v1->v2: set new_asoc as nil in sctp_sendmsg instead of sctp_wait_for_sndbuf.

Pull IPMI updates from Corey Minyard: "This is a fairly large rework of the IPMI code, along with a bunch of smaller fixes. The major changes have been in the next tree for a couple of months, so they should be good to do in. - Some users had IPMI systems where the GUID of the IPMI controller could change. So rescanning of the GUID was added. The naming of some sysfs things was dependent on the GUID, however, so this resulted in the sysfs interface code in IPMI changing to remove that dependency and name the IPMI BMCs like other sysfs devices. - The ipmi_si_intf.c code was fairly bloated with all the different discovery methods (PCI, ACPI, SMBIOS, OF, platform, module parameters, hot add). The structure of how the interfaces were added was redone to make them more modular, then the individual methods were pulled out into their own files" * tag 'ipmi-for-4.15' of git://github.com/cminyard/linux-ipmi: (48 commits) ipmi_si: Delete an error message for a failed memory allocation in try_smi_init() ipmi_si: fix memory leak on new_smi ipmi: remove redundant initialization of bmc ipmi: pr_err() strings should end with newlines ipmi: Clean up some print operations ipmi: Make the DMI probe into a generic platform probe ipmi: Make the IPMI proc interface configurable ipmi_ssif: Add device attrs for the things in proc ipmi_si: Add device attrs for the things in proc ipmi_si: remove ipmi_smi_alloc() function ipmi_si: Move port and mem I/O handling to their own files ipmi_si: Get rid of unused spacing and port fields ipmi_si: Move PARISC handling to another file ipmi_si: Move PCI setup to another file ipmi_si: Move platform device handling to another file ipmi_si: Move hardcode handling to a separate file. ipmi_si: Move the hotmod handling to another file. ipmi_si: Change ipmi_si_add_smi() to take just I/O info ipmi_si: Move io setup into io structure ipmi_si: Move irq setup handling into the io struct ...

Pull rdma updates from Doug Ledford: "This is a fairly plain pull request. Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for.

Pull SELinux updates from Paul Moore: "Seven SELinux patches for v4.15, although five of the seven are small build fixes and cleanups. Of the remaining two patches, the only one worth really calling out is Eric's fix for the SELinux filesystem xattr set/remove code; the other patch simply converts the SELinux hash table implementation to use kmem_cache. Eric's setxattr/removexattr tweak converts SELinux back to calling the commoncap implementations when the xattr is not SELinux related. The immediate win is to fixup filesystem capabilities in user namespaces, but it makes things a bit saner overall; more information in the commit description" * tag 'selinux-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: remove extraneous initialization of slots_used and max_chain_len selinux: remove redundant assignment to len selinux: remove redundant assignment to str selinux: fix build warning selinux: fix build warning by removing the unused sid variable selinux: Perform both commoncap and selinux xattr checks selinux: Use kmem_cache for hashtab_node

Pull audit updates from Paul Moore: "Another relatively small pull request for audit, nine patches total. The only real new bit of functionality is the patch from Richard which adds the ability to filter records based on the filesystem type. The remainder are bug fixes and cleanups; the bug fix highlights include: - ensuring that we properly audit init/PID-1 (me) - allowing the audit daemon to shutdown the kernel/auditd connection cleanly by setting the audit PID to zero (Steve)" * tag 'audit-pr-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: filter PATH records keyed on filesystem magic Audit: remove unused audit_log_secctx function audit: Allow auditd to set pid to 0 to end auditing audit: Add new syscalls to the perm=w filter audit: use audit_set_enabled() in audit_enable() audit: convert audit_ever_enabled to a boolean audit: don't use simple_strtol() anymore audit: initialize the audit subsystem as early as possible audit: ensure that 'audit=1' actually enables audit for PID 1

This matters at least for the mincore syscall, which will otherwise copy uninitialized memory from the page allocator to userspace. It is probably also a correctness error for /proc/$pid/pagemap, but I haven't tested that. Removing the `walk->hugetlb_entry` condition in walk_hugetlb_range() has no effect because the caller already checks for that. This only reports holes in hugetlb ranges to callers who have specified a hugetlb_entry callback. This issue was found using an AFL-based fuzzer. v2: - don't crash on ->pte_hole==NULL (Andrew Morton) - add Cc stable (Andrew Morton) Fixes: 1e25a271 ("mincore: apply page table walker on do_mincore()") Signed-off-by: Jann Horn <jannh@google.com> Cc: <stable@vger.kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
