[Bug 219453] tcpmd5 kernel module regression

2017-05-22 Thread bugzilla-noreply

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219453

--- Comment #3 from Marek Zarychta  ---
FYI something was broken between 11.0-STABLE r318137 and 11.1-PRERELEASE
r318590.
In our setup, TCP MD5 signed packets originate from vlan interface created on
lagg interface, so the issue could be VLAN or LAGG specific. 
I don't know if freshest PRERELEASE works fine. For sure r318137 recompiled
from sources works correctly, although just after the bootup, some packets with
bad signatures occurred:

# netstat -sp tcp | grep signature
8794 packets with matching signature received
18 packets with bad signature received
0 times failed to make signature due to no SA
1 time unexpected signature received
1 time no signature provided by segment

Any holes?

2017-05-22 Thread The Doctor

Just tried to compile a port of www/firefox and most service
except httpd was offline from 90 minutes and www/firefox just stopted compiling
and most services was restored.

Just had to restart a number of Linux boxes virtualised here.

Is this a memory, kernel or Hardware Issue?

The server was purchased from IXSystems using Supermicro  MB

Dual 1.7GHz CPUS

and 16 GB memory 

replacing again BSD/OS 4.3 servers

and have been in service for 10 months now.

2017-05-22 Thread bugzilla-noreply

Bug ID: 219467
   Summary: `mtree -R type -k flags` prints out type= keyword
attributes, contrary to what the manpage says it
should do
   Product: Base System
   Version: CURRENT
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---

  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: n...@freebsd.org

Per mtree(8), passing `-R type -k flags` should clear omit type keywords from
the spec created via mtree:

 -k keywordsUse the type keyword plus the specified (whitespace or
comma separated) keywords instead of the current set
of keywords.  If `all' is specified, use all of the
other keywords.  If the type keyword is not desired,
suppress it with -R type.

Trying this though, demonstrates that that is not the case:

$ sudo mtree -cn -R type -k flags -p /usr/bin/ -x | grep type=
/set type=file flags=uarch
.   type=dir

linux_getrandom.patch

In a Linux-based jail, running Ubuntu 16.04, `lsb_release` command (which is
widely used in various scripts and during Factorio startup) hangs. `top` shows
it forks a `python3.5` process which uses 100% CPU. `truss` shows this process
repeatedly calls `linux_getrandom(…)`, which always returns 0.

`man 2 getrandom` on Ubuntu 16.04 specifies that this syscall should return
number of random bytes written
(http://man7.org/linux/man-pages/man2/getrandom.2.html). A short test program
shows that this it returns positive value on Linux, and returns 0 on FreeBSD
despite the fact that random bytes have been written to the buffer:

> $ cat test_getrandom.c
> #define _GNU_SOURCE
> #include 
> #include 
> #include 
> #include 
> 
> int main(void) {
> int rv;
> int buf = 0;
> rv = syscall(SYS_getrandom, , sizeof(buf), GRND_NONBLOCK);
> printf("getrandom(, %d, 0) => %d buf=%d\n", (int)sizeof(buf), rv, 
> buf);
> return 0;
> }

When this program runs natively on Linux, `getrandom(2)` returns size of
buffer:

> $ ./test_getrandom
> getrandom(, 4, 0) => 4 buf=-707083248

On FreeBSD 12-CURRENT (possibly also on 11-STABLE, r315505 which introduces
this implementation is marked for MFC after 1 month), the syscall always
returns 0:

> $ ./test_getrandom
> getrandom(, 4, 0) => 0 buf=-1643413282

After applying attached patch, return value reported from the test program is
the same as on native Linux, and `lsb_release` no longer hangs:

> $ ./test_getrandom
> getrandom(, 4, 0) => 4 buf=-943351330
> $ lsb_release -a
> No LSB modules are available.
> Distributor ID:   Ubuntu
> Description:  Ubuntu 16.04.2 LTS
> Release:  16.04
> Codename: xenial

Oh-and ... this all worked fine in 11.0-RELEASE (save the ipv6 bug ... which
was supposedly patched in 11.0-STABLE (nice if that stays "fixed" too)).

Bug ID: 219457
   Summary: ZFS ARC eviction & system hangup

  Reporter: vsasja...@gmail.com

I have a machine with 256 GiB of RAM (249 GiB managed) that serves files over
plain HTTP with nginx & AIO.
After system starup ARC grows to its maximum size - ~233 GiB (so about ten gigs
are always free), then it slightly drops down to ~228 GiB. Only after that if I
start some processes:
1. They will immediately hang in "D" state;
2. pagedaemon/uma enters clearing state;
3. ARC starts to evict till its minimum size;
4. When ARC reaches minimum entire system becomes unresponsive with a delay
(from 5 mins to 8 hours).

Some examples of hanging processes:
1. conftest when building devel/m4 (PR in "See Also");
2. tar on any directory, e.g. tar cvf /dev/null /usr/ports.

It works as expected when replacing the 10 with a 5.

Various other parameter combinations work as expected as well and I've used
similar commands for weeks without issues.

The problem is reproducible with other execnames as long as the probe fires.

The "@m = max(arg0)" part isn't required to trigger the assertion but I only
noticed it
after already patching the system where libdtrace is build with reduced
optimizations.

The attached patch prevents the assertion from triggering but may not be the
best solution.

The code flow in dt_print_llquantize() seems strange to me and maybe the
loop should break if "bin" reaches "last_bin" instead. My

Proposed patch (untested)

Thanks. The last trace is very helpful. Can you try this patch? It should be
applicable to both stable/11 and head/.

The problem triggered by error in crypto code. When AES-GCM fails authenticate
decrypted data, it returns EBADMSG error code. This error code was handled
incorrectly in new IPsec code and double free occurred for SA reference. This
patch removed extra free().
