commit fd0c153daad135d0ec1a53c5dbe6936a724d6ae1 upstream.
If we use the ancient SysV syscall ABI, we'd better have tell the
kernel how to claim that a negative return value is a success.
Use ->orig_r2 for that - it's inaccessible via ptrace, so it's
a fair game for changes and it's normally[*] non-negative on return
from syscall. Set to -1; syscall is not going to be restart-worthy
by definition, so we won't interfere with that use either.
[*] the only exception is rt_sigreturn(), where we skip the entire
messing with r1/r2 anyway.

commit 2d631bd58fe0ea3e3350212e23c9aba1fb606514 upstream.
sys_foo() returns -512 (aka -ERESTARTSYS) => do_signal() sees
512 in r2 and 1 in r1.
sys_foo() returns 512 => do_signal() sees 512 in r2 and 0 in r1.
The former is restart-worthy; the latter obviously isn't.

commit b4ab94d6adaa5cf842b68bd28f4b50bc774496bd upstream.
The current code retrieves the TOS field after the lookup
on the ipv4 routing table. The routing process currently
only allows routing based on the original 3 TOS bits, and
not on the full 6 DSCP bits.
As a result the retrieved TOS is cut to the 3 bits.
However for inheriting purposes the full 6 bits should be used.
Extract the full 6 bits before the route lookup and use
that instead of the cut off 3 TOS bits.

commit 3f4093e2bf4673f218c0bf17d8362337c400e77b upstream.
There are use-after-free bugs caused by tst_timer. The root cause
is that there are no functions to stop tst_timer in idt77252_exit().
One of the possible race conditions is shown below:
(thread 1) | (thread 2)
| idt77252_init_one
| init_card
| fill_tst
| mod_timer(&card->tst_timer, ...)
idt77252_exit | (wait a time)
| tst_timer
|
| ...
kfree(card) // FREE |
| card->soft_tst[e] // USE
The idt77252_dev is deallocated in idt77252_exit() and used in
timer handler.
This patch adds del_timer_sync() in idt77252_exit() in order that
the timer handler could be stopped before the idt77252_dev is
deallocated.

commit 32ad11127b95236dfc52375f3707853194a7f4b4 upstream.
This code tries to store -EFAULT in an unsigned int. The
xenbus_file_read() function returns type ssize_t so the negative value
is returned as a positive value to the user.
This change forces another change to the min() macro. Originally, the
min() macro used "unsigned" type which checkpatch complains about. Also
unsigned type would break if "len" were not capped at MAX_RW_COUNT. Use
size_t for the min(). (No effect on runtime for the min_t() change).

commit 4ae97cae07e15d41e5c0ebabba64c6eefdeb0bbe upstream.
The port flag isn't set to `NFP_PORT_CHANGED` when using
`ethtool -m DEVNAME` before, so the port state (e.g. interface)
cannot be updated. Therefore, it caused that `ethtool -m DEVNAME`
sometimes cannot read the correct information.
E.g. `ethtool -m DEVNAME` cannot work when load driver before plug
in optical module, as the port interface is still NONE without port
update.
Now update the port state before sending info to NIC to ensure that
port interface is correct (latest state).

The call to:
ret = simple_write_to_buffer(buf, size, offp, ubuf, size);
will return success if it is able to write even one byte to "buf".
The value of "*offp" controls which byte. This could result in
reading uninitialized data when we do the sscanf() on the next line.
This code is not really desigined to handle partial writes where
*offp is non-zero and the "buf" is preserved and re-used between writes.
Just ban partial writes and replace the simple_write_to_buffer() with
copy_from_user().

This problem is caused by the sort_slabs(). So let's use alphabetic order
when two values are equal in the sort_slabs().
By the way, the content of the `slabinfo -h` is not aligned because the
`-P|--partial Sort by number of partial slabs`
uses tabs instead of spaces. So let's use spaces instead of tabs to fix
it.

commit a3e7b29e30854ed67be0d17687e744ad0c769c4b upstream.
Imagine two non-blocking vsock_connect() requests on the same socket.
The first request schedules @connect_work, and after it times out,
vsock_connect_timeout() sets *sock* state back to TCP_CLOSE, but keeps
*socket* state as SS_CONNECTING.
Later, the second request returns -EALREADY, meaning the socket "already
has a pending connection in progress", even though the first request has
already timed out.
As suggested by Stefano, fix it by setting *socket* state back to
SS_UNCONNECTED, so that the second request will return -ETIMEDOUT.

commit 7e97cfed9929eaabc41829c395eb0d1350fccb9d upstream.
An O_NONBLOCK vsock_connect() request may try to reschedule
@connect_work. Imagine the following sequence of vsock_connect()
requests:
1. The 1st, non-blocking request schedules @connect_work, which will
expire after 200 jiffies. Socket state is now SS_CONNECTING;
2. Later, the 2nd, blocking request gets interrupted by a signal after
a few jiffies while waiting for the connection to be established.
Socket state is back to SS_UNCONNECTED, but @connect_work is still
pending, and will expire after 100 jiffies.
3. Now, the 3rd, non-blocking request tries to schedule @connect_work
again. Since @connect_work is already scheduled,
schedule_delayed_work() silently returns. sock_hold() is called
twice, but sock_put() will only be called once in
vsock_connect_timeout(), causing a memory leak reported by syzbot:

Use mod_delayed_work() instead: if @connect_work is already scheduled,
reschedule it, and undo sock_hold() to keep the reference count

commit ab7e2e0dfa5d37540ab1dc5376e9a2cb9188925d upstream.
According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.

commit 13c9f4dc102f2856e80b92486c41841e25e23772 upstream.
For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.
There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.
