Fix two memory leaks in x86 JIT. For details, please see
individual patches in this series. Thanks!
====================
Signed-off-by: Alexei Starovoitov <ast@kernel.org>
The JIT logic in jit_subprogs() is as follows: for all subprogs we
allocate a bpf_prog_alloc(), populate it (prog->is_func = 1 here),
and pass it to bpf_int_jit_compile(). If a failure occurred during
JIT and prog->jited is not set, then we bail out from attempting to
JIT the whole program, and punt to the interpreter instead. In case
JITing went successful, we fixup BPF call offsets and do another
pass to bpf_int_jit_compile() (extra_pass is true at that point) to
complete JITing calls. Given that requires to pass JIT context around
addrs and jit_data from x86 JIT are freed in the extra_pass in
bpf_int_jit_compile() when calls are involved (if not, they can
be freed immediately). However, if in the original pass, the JIT
image didn't converge then we leak addrs and jit_data since image
itself is NULL, the prog->is_func is set and extra_pass is false
in that case, meaning both will become unreachable and are never
cleaned up, therefore we need to free as well on !image. Only x64
JIT is affected.

The Python script used to parse and extract eBPF helpers documentation
from include/uapi/linux/bpf.h expects a very specific formatting for the
descriptions (single dot represents a space, '>' stands for a tab):
/*
...
*.int bpf_helper(list of arguments)
*.> Description
*.> > Start of description
*.> > Another line of description
*.> > And yet another line of description
*.> Return
*.> > 0 on success, or a negative error in case of failure
...
*/
This is too strict, and painful for developers who wants to add
documentation for new helpers. Worse, it is extremely difficult to check
that the formatting is correct during reviews. Change the format
expected by the script and make it more flexible. The script now works
whether or not the initial space (right after the star) is present, and
accepts both tabs and white spaces (or a combination of both) for
indenting description sections and contents.
Concretely, something like the following would now be supported:
/*
...
*int bpf_helper(list of arguments)
*......Description
*.> > Start of description...
*> > Another line of description
*..............And yet another line of description
*> Return
*.> ........0 on success, or a negative error in case of failure
...
*/
While at it, remove unnecessary carets from each regex used with match()
in the script. They are redundant, as match() tries to match from the
beginning of the string by default.

Previously the bbr->idle_restart tracking was zeroing out the
bbr->idle_restart bit upon ACKs that did not SACK or ACK anything,
e.g. receiving incoming data or receiver window updates. In such
situations BBR would forget that this was a restart-from-idle
situation, and if the min_rtt had expired it would unnecessarily enter
PROBE_RTT (even though we were actually restarting from idle but had
merely forgotten that fact).
The fix is simple: we need to remember we are restarting from idle
until we receive a S/ACK for some data (a S/ACK for the first flight
of data we send as we are restarting).

In dual_mac mode packets arrived on one port should not be forwarded by
switch hw to another port. Only Linux Host can forward packets between
ports. The below test case (reported in [1]) shows that packet arrived on
one port can be leaked to anoter (reproducible with dual port evms):
- connect port 1 (eth0) to linux Host 0 and run tcpdump or Wireshark
- connect port 2 (eth1) to linux Host 1 with vlan 1 configured
- ping <IPx> from Host 1 through vlan 1 interface.
ARP packets will be seen on Host 0.
Issue happens because dual_mac mode is implemnted using two vlans: 1 (Port
1+Port 0) and 2 (Port 2+Port 0), so there are vlan records created for for
each vlan. By default, the ALE will find valid vlan record in its table
when vlan 1 tagged packet arrived on Port 2 and so forwards packet to all
ports which are vlan 1 members (like Port.
To avoid such behaviorr the ALE VLAN ID Ingress Check need to be enabled
for each external CPSW port (ALE_PORTCTLn.VID_INGRESS_CHECK) so ALE will
drop ingress packets if Rx port is not VLAN member.

Also improve the comments and some other details while at it:
- Don't mix same-line and previous-line comment style on otherwise
identical code patterns within the same function,
- capitalize 'BPF' and x86 register names consistently,
- capitalize sentences consistently,
- instead of 'x64' use 'x86-64': x64 is a Microsoft specific term,
- use more consistent punctuation,
- use standard coding style in macros as well,
- fix typos and a few other minor details.

Applications with many concurrent connections, high variance
in receive queue length and tight memory bounds cannot
allocate worst-case buffer size to drain sockets. Knowing
the size of receive queue length, applications can optimize
how they allocate buffers to read from the socket.
The number of bytes pending on the socket is directly
available through ioctl(FIONREAD/SIOCINQ) and can be
approximated using getsockopt(MEMINFO) (rmem_alloc includes
skb overheads in addition to application data). But, both of
these options add an extra syscall per recvmsg. Moreover,
ioctl(FIONREAD/SIOCINQ) takes the socket lock.
Add the TCP_INQ socket option to TCP. When this socket
option is set, recvmsg() relays the number of bytes available
on the socket for reading to the application via the
TCP_CM_INQ control message.
Calculate the number of bytes after releasing the socket lock
to include the processed backlog, if any. To avoid an extra
branch in the hot path of recvmsg() for this new control
message, move all cmsg processing inside an existing branch for
processing receive timestamps. Since the socket lock is not held
when calculating the size of receive queue, TCP_INQ is a hint.
For example, it can overestimate the queue size by one byte,
if FIN is received.
With this method, applications can start reading from the socket
using a small buffer, and then use larger buffers based on the
remaining data when needed.
V3 change-log:
As suggested by David Miller, added loads with barrier
to check whether we have multiple threads calling recvmsg
in parallel. When that happens we lock the socket to
calculate inq.
V4 change-log:
Removed inline from a static function.

To make eBPF program load time easier to parse from "bpftool prog"
output for machines, change the time format used by the program. The
format now differs for plain and JSON version:
- Plain version uses a string formatted according to ISO 8601.
- JSON uses the number of seconds since the Epoch, wich is less friendly
for humans but even easier to process.
Example output:
# ./bpftool prog
41298: xdp tag a04f5eef06a7f555 dev foo
loaded_at 2018-04-18T17:19:47+0100 uid 0
xlated 16B not jited memlock 4096B
# ./bpftool prog -p

Previously, "Apr 18/17:19" would be used at both places.

This is needed to link ipv6 as a loadable module, which in turn happens
in allmodconfig.

We already have memcpy_toio(), but not memset_io(), so let's
add the obvious version to allow building an allmodconfig kernel
without errors like
drivers/gpu/drm/ttm/ttm_bo_util.c: In function 'ttm_bo_move_memcpy':
drivers/gpu/drm/ttm/ttm_bo_util.c:390:3: error: implicit declaration of function 'memset_io' [-Werror=implicit-function-declaration]

Because the current statistics for size 8192~12287 are only valid for GE,
the ranges of 8192~9216 and 9217~12287 are valid only for LGE/CGE, and are
always 0 for GE interfaces. it is easy to cause confusion when viewing the
packet statistics using the command ethtool -S.
This patch removes the 8192~12287 range of packet statistics and uses the
8192~9216 and 9217~12287 ranges for statistics. This change depends on the
firmware upgrade.

There are two level of vlan tables in hardware, one is port vlan
which is shared by all functions, the other one is function
vlan table, each function has it's own function vlan table.
Currently, PF sets the port vlan table, and vf sets the function
vlan table, which will cause packet lost problem.
This patch fixes this problem by setting both vlan table, and
use hdev->vlan_table to manage thet port vlan table.

If head has invlid value then a dead loop can be triggered in
hclge_cmd_csq_clean. This patch adds sanity check for this case.
