Forum OpenACS Development: Re: NaviServer on Windows: [ns_info threads] returning unbalanced braces

@frank i will send you the binaries that i've compiled, but be patient, i am on seldom on that machine. the binaries are built with win7, 64bit, plain naviserver installation ( i.e. no ssl or db-drivers); including the test-files for calling "ns_into threads" while the ticker is running; i've no idea, how well these run on different windows versions, but it seems that windows will pick up the binaries from the ns/bin/ directory. Will send you the binaries via mail. When building the server, i was essentially following the instructions of Makefile.win32 in the NaviServer distribution, but used different paths.

just now, i've tested to load larger files with these binaries. the largest .html files on that machine were 1.4 and 1.5 MB large, but these load without problems:

127.0.0.1 - - [07/Mar/2017:13:05:09 +0100] "GET /dt.html HTTP/1.1" 200 1432756 "" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0" 
127.0.0.1 - - [07/Mar/2017:13:07:32 +0100] "GET /im.html HTTP/1.1" 200 1528278 "" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0" 
@frank & maurizio: Since you have compiled fresh binaries, have you checked the debugging hooks mentioned above to find the source for the broken thread-info from the "-ticker-" thread?

@frank: Do you see any messages in the error.log around the time, when processing of large files stops?

sorry for the slower replies, I've very little time resources currently, full next week i'll be in china.

Hi Gustaf,

> win 7

Compatibility between Windows versions doesn't seem to be any issue.

> no ssl or db-drivers

I don't care about SSL. I understand I'll be able to take the db-driver DLLs from Maurizio's binaries, right?

> any messages

Nope, none!

Thanks for reacting under such a pressure. Thanks for warning about next week.

Cheers,
Frank

Dear all, sorry for my late post but I did lots of tests and now I am even more confused than before... :-) :-) :-) This is what I found: 1. I took a single Windows machine, I installed Naviserver from my installer. 2. naviserver is answering on localhost, port 8000. 3. Then I installed on the same machine Nginx. this is the config:
# user www-data;
worker_processes  1;

# error_log  /var/log/nginx/error.log;
# pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
    multi_accept on;
}

http {
  server_names_hash_bucket_size 64;
  
  server {
    listen 80;
    server_name openacs.local.lan;
    client_max_body_size 12M;
    location / {
      proxy_pass http://localhost:8000;
      proxy_connect_timeout 5;
      proxy_send_timeout    5;
      proxy_read_timeout  43200;
      proxy_set_header  X-Forwarded-For $remote_addr;
    }
  }
  }

In the /etc/hosts (yes, there's such a file also on Windows) I put the follwing:
127.0.0.1       openacs.local.lan
The Openacs Config had the following lines:
# change to 80 and 443 for production use
set httpport                  8000
set httpsport                 8443 

# The hostname and address should be set to actual values.
# setting the address to 0.0.0.0 means aolserver listens on all interfaces
set hostname                  localhost
set address                   localhost
With all of this in place, trying to get a big file via Nginx, that is: http://openacs.local.lan/acs-admin/ext-all.js works without any problem on the contrary http://localhost:8000/acs-admin/ext-all.js stops and never returns

I'm very confused by this result.
Maurizio

Dear all,
the problem observed by Frank and proved by Brian and myself, is caused by a bad memory allocation handling in the file "sockfile.c", function "SendFd".
Here you can see the problem and the fix:
http://www.spazioit.com/images/naviserver/mem_alloc_error.jpg
When a file has line too long (longer than 16384 bytes) we have a buffer overflow. The limit is now 64 MB and should be more than adequate also for larke JS application compressed and obfuscated in one single line.
Linux systems that have a working "sendfile" function may not have had the need to call the "SendFd" function and this is a possible explanation why the issue did not show up in these systems.
I blieve I need to say:
1. it wasn't a compilation error/problem
2. instead of always complaining about Windows, most of the times Windows is nothing else than a different platforms exposing other problems, other issues present in our work.
A new version of the installer is on its way.
This time the build system is Visual Studio 2017

Kind regards,
Maurizio

Hi Maurizio,

Great to see you found the issue. I'm looking forward to include your quick fix in the ]po[ Windows installer ASAP.

However, you can't leave such a security hole in NaviServer permanently! I'm not a NaviServer expert (I never looked into the code...), but I know there are many ways in C to deliver file contents safely and with a smaller buffer...

Frank

Dear Frank,
as you properly noted it is a quick fix. I spent too much time compiling...
I hope that now the people knowing Naviserver much better than I do will convert my quick and dirty fix into something properly done.
Maurizio
The situation is quite strange. in my compiled binary, there is no buffer overflow, so the diagnosis is not correct at least for "my" compile. I've added a few more debugging help statements for maurizio to get more clearness ( NaviServer commit).

with these debugging statements activated i see on large downloads the following output

[10/Mar/2017:11:56:55][336.73c][-conn:default:4-] Notice: SendFd offset 0 length 1528060

so, maybe there is a difference between compiles with Visual Studio 11 and newer versions. But that was the last i can do on the windows front for the next 10-14 days.

Hi!

Just FYI, Maurizio just 5 min ago provided me with a workaround/fix for the nsd.exe "hang" issue. He'll later explain what he did.

Cheers,
Frank

There is no need for a rush from my side. i prefer a deeper analysis of the cause over a quick hack to fix the symptoms.
Dear Gustaf,
this is not a quick hack to fix the symptoms.
This is a properly working version of the SendFd function:

#define MAX_BUF_SIZE 16384
static ssize_t
SendFd(Ns_Sock *sock, int fd, off_t offset, size_t length,
const Ns_Time *timeoutPtr, unsigned int flags,
Ns_DriverSendProc *sendProc)
{
static char buf[MAX_BUF_SIZE+1];
struct iovec iov;
ssize_t nwrote = 0, toRead = (ssize_t)length, result;
bool decork;

decork = Ns_SockCork(sock, NS_TRUE);
while (toRead > 0) {
ssize_t sent, nread;

nread = pread(fd, buf, MIN((size_t)toRead, MAX_BUF_SIZE), offset);
if (nread <= 0) {
break;
}
toRead -= nread;
offset += (off_t)nread;

buf[nread] = '\0';

(void) Ns_SetVec(&iov, 0, buf, (size_t)nread);
sent = (*sendProc)(sock, &iov, 1, timeoutPtr, flags);
if (sent > 0) {
nwrote += sent;
}

if (sent != nread) {
break;
}
}

if (decork) {
(void) Ns_SockCork(sock, NS_FALSE);
}

if (nwrote > 0) {
result = nwrote;
} else {
result = -1;
}

return result;
}

The "hacks" I made are in bold.
1: I made the buffer static.
2: I added a +1 in the buffer size
3: I used MAX_BUF_SIZE, that is size(buf) -1 in the MIN function
4. As safety I put a buf[nread] = '\0'; statement.

Up to you.... to decide what we are talking about... if hacks in the solution or bugs in the original version of the function.

I do use hacks to verify if a portion of code is responsible or not for a problem, but then, if and when I have time, I try to convert these hacks into proper bug fixes.

You are very welcome to analyze, discover, why the original version of the function causes memory allocation problems (in the stack...) if the content is bigger than 16384 and understand what my hacks do.

For sure we are not facing a compilation issue/problem.

Thank you,
Maurizio

some comments about the newly suggested changes, which are different to the previous suggestions:
* by making the buffer static, the code becomes subject to random results in concurrent operations
* pread() reads binary data. there is no need for \0 termination

questions:
* why should making the buffer static help against a buffer overflow (as you stated above)?
* what is the result of the debugging lines (that i have added to bitbucket) in your installation?
* do you get the same problems with the config-file, that i have sent to you?
* if the config file and the test case is the same, what is your explanation that the original code works flawlessly with visual studio 11 (my installation) but not with visual studio 2017 (your installation)?

A possible explanation would be that the thread stack size is different (maybe different due to a different config file), but for that i require answers to the questions i have asked before.

If the code patterns above are really a problem, there are many places in the code that have to be altered.

btw, the OpenACS forum is not the right place for this discussion.

Dear Gustaf,
thank you for your questions.
The new version of the function I'm using is here below:
#define MAX_BUF_SIZE 16384
#define ACC_DELAY 5
static ssize_t
SendFd(Ns_Sock *sock, int fd, off_t offset, size_t length,
const Ns_Time *timeoutPtr, unsigned int flags,
Ns_DriverSendProc *sendProc)
{
char buf[MAX_BUF_SIZE + 1];
struct iovec iov;
ssize_t nwrote = 0, toRead = (ssize_t)length, result;
bool decork;

decork = Ns_SockCork(sock, NS_TRUE);
while (toRead > 0) {
ssize_t sent, nread;

nread = pread(fd, buf, MIN((size_t)toRead, MAX_BUF_SIZE), offset);
if (nread <= 0) {
break;
}
toRead -= nread;
offset += (off_t)nread;

buf[nread] = '\0';

(void) Ns_SetVec(&iov, 0, buf, (size_t)nread);
sent = (*sendProc)(sock, &iov, 1, timeoutPtr, flags);
Sleep(ACC_DELAY);
if (sent > 0) {
nwrote += sent;
}

if (sent != nread) {
break;
}
}

if (decork) {
(void) Ns_SockCork(sock, NS_FALSE);
}

if (nwrote > 0) {
result = nwrote;
} else {
result = -1;
}

return result;
}

Now the answers to your questions:
questions:
* why should making the buffer static help against a buffer overflow (as you stated above)?
because, if I do not use the buffer static, the code as it is stops working. I believe it is a timing issue. The send operation still takes place when the function is finished.
If I want to remove the static, I need to introduce a delay after the call to (*sendProc). I know this is a ugly fix, perhaps you can investigate this issue. But with this delay the code works and it is thread safe.

* what is the result of the debugging lines (that i have added to bitbucket) in your installation?
I did not check them.
* do you get the same problems with the config-file, that i have sent to you?
I did not try the binaries. I will try with the config-file and let you know.

Hello Gustaf,
I did try the original version of the code + your debugging hooks and I did try it with the nsd-config file you sent me.
And I observed the very same behaviour we saw at the beginning. When the content is larger than 16384 naviserver goes into a sort endless loop and it consumes lots of system resources.
The problem disappears if I make the (in)famous buffer static or if I put a delay after the send, like I did in here:

#define MAX_BUF_SIZE 16384
#ifdef _WIN32
#define AC_DELAY 5
#endif
static ssize_t
SendFd(Ns_Sock *sock, int fd, off_t offset, size_t length,
const Ns_Time *timeoutPtr, unsigned int flags,
Ns_DriverSendProc *sendProc)
{
char buf[MAX_BUF_SIZE+1];
struct iovec iov;
ssize_t nwrote = 0, toRead = (ssize_t)length, result;
bool decork;

// Ns_Log(Notice, "SendFd offset %ld length %lu", offset, length);

decork = Ns_SockCork(sock, NS_TRUE);
while (toRead > 0) {
ssize_t sent, nread;

nread = pread(fd, buf, MIN((size_t)toRead, MAX_BUF_SIZE), offset);

// Ns_Log(Notice, "... pread toread %lu offset %ld => read %ld", MIN((size_t)toRead, sizeof(buf)), offset, nread);
if (nread <= 0) {
break;
}
toRead -= nread;
offset += (off_t)nread;

(void) Ns_SetVec(&iov, 0, buf, (size_t)nread);
sent = (*sendProc)(sock, &iov, 1, timeoutPtr, flags);
#ifdef _WIN32
Sleep(AC_DELAY);
#endif
if (sent > 0) {
nwrote += sent;
}

if (sent != nread) {
break;
}
}

if (decork) {
(void) Ns_SockCork(sock, NS_FALSE);
}

if (nwrote > 0) {
result = nwrote;
} else {
result = -1;
}

return result;
}

I have the feeling that without that delay, some of the read/write on the buff is still occurring even when the function has finished, but then the actual content of that memory area at that moment is not what we had in the (in)famous buffer. By making the buffer static, the memory stays there... but the solution is not thread safe (obviously).
Putting the delay is an ugly fix, but it is thread safe and it does work.

No further digging.

Maurizio

from the transit: nobody is interested in "explanations" like "if I do not use the buffer static, the code as it is stops working" hinting on symptoms, but on constructive feedback, helping to find the cause of the differences (why can i not reproduce these symptoms with the small provided example configuration)? If it is e.g. a stack size problem, the the same cause can be responsible for other broken behavior (like the one of the begin of this thread).

M: "i did try ... and I observed the very same behavior..." What is the output from the debugging lines? I am interested in an output like in http://openacs.org/forums/message-view?message_id=5354342

There is no need for a rush from my side. On Monday, i'll be back in Vienna, and it will take me at least one week to recover from jet lag and work backlog, before i can make one more attempt with a newer version of visual studio.

Dear Gustaf...
let's be "constructive"...
1. the code:
#define MAX_BUF_SIZE 16384
#ifdef _WIN32
#define AC_DELAY 5
#endif
static ssize_t
SendFd(Ns_Sock *sock, int fd, off_t offset, size_t length,
const Ns_Time *timeoutPtr, unsigned int flags,
Ns_DriverSendProc *sendProc)
{
char buf[MAX_BUF_SIZE];
struct iovec iov;
ssize_t nwrote = 0, toRead = (ssize_t)length, result;
bool decork;

// Ns_Log(Notice, "SendFd offset %ld length %lu", offset, length);

decork = Ns_SockCork(sock, NS_TRUE);
while (toRead > 0) {
ssize_t sent, nread;

nread = pread(fd, buf, MIN((size_t)toRead, sizeof(buf)), offset);

Ns_Log(Notice, "... pread toread %lu offset %ld => read %ld", MIN((size_t)toRead, sizeof(buf)), offset, nread);
if (nread <= 0) {
break;
}
toRead -= nread;
offset += (off_t)nread;

(void) Ns_SetVec(&iov, 0, buf, (size_t)nread);
sent = (*sendProc)(sock, &iov, 1, timeoutPtr, flags);
#ifdef _WIN32
// Sleep(AC_DELAY);
#endif
if (sent > 0) {
nwrote += sent;
}

if (sent != nread) {
break;
}
}

if (decork) {
(void) Ns_SockCork(sock, NS_FALSE);
}

if (nwrote > 0) {
result = nwrote;
} else {
result = -1;
}

return result;
}
2. let's download a file of 6.68 MB...

3. without delay, the output is this:

Dear Gustaf,
SendFd in sockfile calls
(*sendProc)(sock, &iov, 1, timeoutPtr, flags)...
Well this is a ptr function, eventually the function WSASend(in nssock.c/264) gets called.
But this is an asynchronous call.
This is why, I had to put a delay (an ugly fix I know) immediately after the call inside SendFd.
Whithout this delay, the WSASend can still work even after the SendFd is finished, that is when the buffer "buf" does not exists any longer in the stack. And this is why a static buffer prevents the problem from occurring (of course at the cost of the function non being thread safe).
A proper solution would be using WASSend completion routines. I believe this could be the reason why we see memory corruption problems:
http://www.serverframework.com/asynchronousevents/2015/01/wsarecv-wsasend-and-thread-safety.html

This is design, coding error and it has nothing to do with the compiler, the compiler options and so on....

Hope it helps,
Maurizio

Errata-Corrige
1. In teory, "WSASend", called within "SockSend", is called with the last two parameters set to NULL should be blocking... so no problem should occur.
2. when replacing "WSASend" with a normal "send", "SockSend" works without problems
3. "WSASend" by "SockSend also by AOLserver.
Probably the behaviour fo the "WSASend" has changed with the latest version of Windows and/or Visual C/C++.

I will update the code consequently.

Maurizio

Dear Maurizio at al,

I've installed Visual Studio 2017 on a VM, and could reproduce the first error of this forums thread. As expected, there was a change in Visual Studio: with version 2015, Microsoft changed with the introduction of the Universal CRT the behavior of _vsnprintf, which is not longer identical to _vsnprintf, but complies now with the C99 standard.

This change in Visual Studio affects potentially many places in the code and explains, why i could not reproduce the mentioned problem with Visual Studio 11. Maybe this is also related to the problem with large files (which i still can't reproduce).

it is not unlikely, that there are still more fixes necessary when compiling with Visual Studio 2015 or newer, but at least the problem with the "unbalanced brackets" should be fixed.

The changes are committed to bitbucket.

Dear Gustaf,
thank you very much for having replicated the issue.
I'm not sure I agree completely with your explanation.
If you're explanation was correct how come the following small modification (which I believe is the memory bug I was referring too) in the file dstring.c,
// #ifdef _WIN32
// while (result == -1 && errno == ERANGE) {
// newLength = dsPtr->spaceAvl * 2;
//#else
if ((size_t)result >= bufLength) {
newLength = dsPtr->spaceAvl + (result - (int)bufLength);
//#endif
makes:
1. the problem with the unbalanced braces disappear
2. the odd characters in the log disappear
3. the erratic behaviour disappear?

Thank you,
Maurizio

I saw your fix, in the same file, in the same area... we can call it as we want....
1. a compilation issue
2. a matter of compliance with standards...

but at the end of the day it is a memory allocation problem causing wrong/erratic behaviour.

This does not solve the long file problem, which at the moment I "fixed" not using a delay, but replacing WSASend with a plain send. I do not know why the second works and the first one doesn't.

Thank you,
Maurizio

maurizio, does this mean, you see with this change still the "unbalanced braces" issue? If so, make sure, that in your local changes, you do not alter the definitions of naviserver in respect to snprintf/vsnprintf (as it was in the case with the changes you sent to me around April 2016).

Background: the committed change (not sure, if the snippet you posted is the same) affects the dstring infrastructure, which is all over the code to append to a string. A buffer overflow on such a string can have many weird effects. Up to Visual Studio 2015, the functions vsnprintf() and _vsnprintf() behaved in the same, microsoft specific way, namely returning -1 in case, the provided buffer was too small, not guaranteeing null termination.

With the introduction of Visual Studio 2015, the behavior of vsnprintf() changed to become c99 compliant, but __vsnprintf() stayed the same. the c99 standard states, that in cases where the buffer is too small, the function should return the number of bytes that would have been written. That is a very different behavior for recognizing buffer grow requests and buffer size management. The same change of behavior also affects e.g. snprintf()/_snprintf(). So, when using these functions, a change from a Visual Studio before version 2015 to a newer version requires code changes. Convince yourself by compiling with an earlier version of Visual Studio!

So far, i see no obvious connection between the dstring function and the WSASend() problem. So far, i could not reproduce this issue. I tried yesterday multiple times with requests for a 6+ MB file, but everything worked fine. I find it hard to believe, that the specification

if both lpOverlapped and lpCompletionRoutine are NULL, the socket in this function will be treated as a non-overlapped socket. (https://msdn.microsoft.com/en-us/library/windows/desktop/ms742203.aspx)
is not valid in newer versions.

If someone has instructions, how to reproduce the issue reliably, i would appreciate it. i can't test maurizio's binaries in my setup, since i don't have 10GB free on the c: partition, and i failed to extend the partition in the vm under mac os x; so i need probably a different, completely new setup, for which i have no time now).

Dear Gustaf,
I've tried all combinations... here's the result:

the original code was:

DWORD n1;
if (WSASend(sock, (LPWSABUF)bufs, nbufs, &n1, flags,
NULL, NULL) != 0) {
n1 = -1;
}
n = n1;

and it DOES NOT WOK

I then used the readability improvement modification you posted this morning at 09:57:40
DWORD bytesReceived;
int rc;

rc = WSASend(sock, (LPWSABUF)bufs, nbufs, &bytesReceived, flags,
NULL, NULL);

if (rc == 0) {
n = bytesReceived;
} else {
n = -1;
}
and it DOES WORK

My original fix was to use a plain send
# if _MSC_VER < 1900
DWORD n1;
if (WSASend(sock, (LPWSABUF)bufs, nbufs, &n1, flags,
NULL, NULL) != 0) {
n1 = -1;
}
n = n1;
#else
n = send(sock, (LPWSABUF)bufs[0].iov_base, bufs[0].iov_len, flags);

#endif

and it DOES WORK

I will include your modification in my distribution, though I cannot see any difference between the first two implementations, but the code is here if anyone wants to check.

Thank you very much,
Maurizio

Do i read your mail correctly that now all know issues are gone? That would be great.

Concerning the change around WSAsend(): The difference is not easy to spot but due to a type conversion, since n1 (type DWORD) was originally assigned -1 in error conditions. Since DWORD is defined as unsigned 32bit quantity, bad things happen when its value is assigned to a type of a different size and signedness (here: ssize_t; probably not an issue in 32bit versions). Interestingly, this type issue is not flagged by sonarsrv: the current version of nssock.c in sonarsrv is still the "old" code and shows 0 issues [1]. I've cleaned this code yesterday to prepare for debugging return-codes from WSASend().

Concerning send(): When send() is used as shown in your snippet, the code will produce incorrect results when nbufs <> 1. The reason for using WSAsend() instead of send() is that the former supports the more efficient scatter/gather interface.

all the best

Dear Gustaf,
I believe all issues we have been facing are gone.
They were caused by two errors:
1. memory allocation problem (in dstring.c)
2. bad handling of the WSASend call.

I do not know if you saw it or not. But looking into possible causes for these problems I noticed that EINTR is not handled in a generic way as EWOULDBLOCK and EINPROGRESS. Perhaps it would make sense to normalize also EINTR.

Thank you,
Maurizio
