Dmitry Torokhov 5f81880d52 sysfs, kobject: allow creating kobject belonging to arbitrary users
Normally kobjects and their sysfs representation belong to global root,
however it is not necessarily the case for objects in separate namespaces.
For example, objects in separate network namespace logically belong to the
container's root and not global root.

This change lays groundwork for allowing network namespace objects
ownership to be transferred to container's root user by defining
get_ownership() callback in ktype structure and using it in sysfs code to
retrieve desired uid/gid when creating sysfs objects for given kobject.

Dmitry Torokhov 488dee96bb kernfs: allow creating kernfs objects with arbitrary uid/gid
This change allows creating kernfs files and directories with arbitrary
uid/gid instead of always using GLOBAL_ROOT_UID/GID by extending
kernfs_create_dir_ns() and kernfs_create_file_ns() with uid/gid arguments.
The "simple" kernfs_create_file() and kernfs_create_dir() are left alone
and always create objects belonging to the global root.

When creating symlinks ownership (uid/gid) is taken from the target kernfs
object.

Pablo Neira Ayuso says:

====================
Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for your net-next
tree:

1) No need to set ttl from reject action for the bridge family, from
   Taehee Yoo.

2) Use a fixed timeout for flow that are passed up from the flowtable
   to conntrack, from Florian Westphal.

3) More preparation patches for tproxy support for nf_tables, from Mate
   Eckl.

4) Remove unnecessary indirection in core IPv6 checksum function, from
   Florian Westphal.

5) Use nf_ct_get_tuplepr() from openvswitch, instead of opencoding it.
   From Florian Westphal.

6) socket match now selects socket infrastructure, instead of depending
   on it. From Mate Eckl.

7) Patch series to simplify conntrack tuple building/parsing from packet
   path and ctnetlink, from Florian Westphal.

8) Fetch timeout policy from protocol helpers, instead of doing it from
   core, from Florian Westphal.

9) Merge IPv4 and IPv6 protocol trackers into conntrack core, from
   Florian Westphal.

10) Depend on CONFIG_NF_TABLES_IPV6 and CONFIG_IP6_NF_IPTABLES
    respectively, instead of IPV6. Patch from Mate Eckl.

11) Add specific function for garbage collection in conncount,
    from Yi-Hung Wei.

12) Catch number of elements in the connlimit list, from Yi-Hung Wei.

13) Move locking to nf_conncount, from Yi-Hung Wei.

14) Series of patches to add lockless tree traversal in nf_conncount,
    from Yi-Hung Wei.

15) Resolve clash in matching conntracks when race happens, from
    Martynas Pumputis.

16) If connection entry times out, remove template entry from the
    ip_vs_conn_tab table to improve behaviour under flood, from
    Julian Anastasov.

17) Remove useless parameter from nf_ct_helper_ext_add(), from Gao feng.

18) Call abort from 2-phase commit protocol before requesting modules,
    make sure this is done under the mutex, from Florian Westphal.

19) Grab module reference when starting transaction, also from Florian.

20) Dynamically allocate expression info array for pre-parsing, from
    Florian.

21) Add per netns mutex for nf_tables, from Florian Westphal.

22) A couple of patches to simplify and refactor nf_osf code to prepare
    for nft_osf support.

23) Break evaluation on missing socket, from Mate Eckl.

24) Allow to match socket mark from nft_socket, from Mate Eckl.

25) Remove dependency on nf_defrag_ipv6, now that IPv6 tracker is
    built-in into nf_conntrack. From Florian Westphal.

Jon Maloy 40999f11ce tipc: make link capability update thread safe
The commit referred to below introduced an update of the link
capabilities field that is not safe. Given the recently added
feature to remove idle node and link items after 5 minutes, there
is a small risk that the update will happen at the very moment the
targeted link is being removed. To avoid this we have to perform
the update inside the node item's write lock protection.

Linus Torvalds bfa54a3a00 Power management fix for 4.18-rc6
Fix a relatively old initialization issue in intel_pstate causing
 the pcc-cpufreq driver to be used instead of it on some HP Proliant
 systems, which turned into a functional regression during the 4.17
 cycle, because pcc-cpufreq is a scalability disaster and that was
 amplified by the idle loop rework done at that time (Rafael Wysocki).

Damien Thébault 2502e5a025 platform/x86: dell-laptop: Fix backlight detection
Fix return code check for "max brightness" ACPI call.

The Dell laptop ACPI video brightness control is not present on dell
laptops anymore, but was present in older kernel versions.

The code that checks the return value is incorrect since the SMM
refactoring.

The old code was:
  if (buffer->output[0] == 0)

Which was changed to:
  ret = dell_send_request(...)
  if (ret)

However, dell_send_request() will return 0 if buffer->output[0] == 0,
so we must change the check to:
  if (ret == 0)

This issue was found on a Dell M4800 laptop, and the fix tested on it
as well.

This was causing problems on a system with a large amount of RAM, where
display push buffers were being fetched incorrectly when placed in high
system memory addresses.

While this commit will resolve the issue on that particular system, the
issue will be avoided completely with another patch to more fully solve
problems with display and large amounts of system memory on Pascal.

It's still probably a good idea to disable this to prevent weird issues

====================
docs: Convert alias and bridge to rst

Here is my first attempt at working on converting docs in
Documentation/networking to rst format.  I've picked a couple of trivial
ones to start with.  If there is anything extra I can do to make your
life easier during documentation conversion please say.  (Also if there
is some reason that it would be preferable to _not_ embark on this task
please say :)

This set does not make any changes to the converted files apart from
formatting.

v2:
 - remove incorrect patch from set (changing 'Indices' indentation)

Randy Dunlap e56b8ce363 tcp: identify cryptic messages as TCP seq # bugs
Attempt to make cryptic TCP seq number error messages clearer by
(1) identifying the source of the message as "TCP", (2) identifying the
errors as "seq # bug", and (3) grouping the field identifiers and values
by separating them with commas.

E.g., the following message is changed from:

recvmsg bug 2: copied 73BCB6CD seq 70F17CBE rcvnxt 73BCB9AA fl 0
WARNING: CPU: 2 PID: 1501 at /linux/net/ipv4/tcp.c:1881 tcp_recvmsg+0x649/0xb90

to:

Jakub Kicinski f15f084ff1 pktgen: convert safe uses of strncpy() to strcpy() to avoid string truncation warning
GCC 8 complains:

net/core/pktgen.c: In function ‘pktgen_if_write’:
net/core/pktgen.c:1419:4: warning: ‘strncpy’ output may be truncated copying between 0 and 31 bytes from a string of length 127 [-Wstringop-truncation]

net/core/pktgen.c:1268:4: warning: ‘strncpy’ output may be truncated copying between 0 and 31 bytes from a string of length 127 [-Wstringop-truncation]
    strncpy(pkt_dev->dst_min, buf, len);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is no bug here, but the code is not perfect either.  It copies
sizeof(pkt_dev->/member/) - 1 from user space into buf, and then does
a strcmp(pkt_dev->/member/, buf) hence assuming buf will be null-terminated
and shorter than pkt_dev->/member/ (pkt_dev->/member/ is never
explicitly null-terminated, and strncpy() doesn't have to null-terminate
so the assumption must be on buf).  The use of strncpy() without explicit
null-termination looks suspicious.  Convert to use straight strcpy().

strncpy() would also null-pad the output, but that's clearly unnecessary
since the author calls memset(pkt_dev->/member/, 0, sizeof(..)); prior
to strncpy(), anyway.

While at it format the code for "dst_min", "dst_max", "src_min" and
"src_max" in the same way by removing extra new lines in one case.
