libcurl v7.88.1 crash on cleanup with missing cookie file #10694

Keitagit-kun · 2023-03-06T22:11:03Z

I get crush with libcurl v7.88.1 on call to curl_easy_cleanup() if cookies file is not exists originally.
If I manually create blank text-file (with relevant filename) - there a no crush and file content successfully written (in my test case only header as there is no cookies).
Without CURLOPT_COOKIEJAR option set - there a no crush...
With libcurl v7.86.0 crush did not happen, but also cookies file was not created/written.
If I remember right, with some previous version cookiesfile was created without problems...
Cookes engine setup (Windows):

curl_easy_setopt(cURLHandle, CURLOPT_COOKIESESSION, 1L)
curl_easy_setopt(cURLHandle, CURLOPT_COOKIEFILE, sCookiesFilePath)
curl_easy_setopt(cURLHandle, CURLOPT_COOKIEJAR, sCookiesFilePath)

on beginning of connection log there a message:
WARNING: failed to open cookie file "* full file path to cookie file *"

I expected the following

I expected cookes file is created/written by libcurl...

The text was updated successfully, but these errors were encountered:

Thanks a lot for your report!

I've failed to reproduce this problem myself, so can I ask you to provide us with more details on how to go ahead and repeat this. Preferably with a command line or a stand-alone program we can run from our ends against a public URL to trigger the problem?

bagder · 2023-03-06T23:04:53Z

From my reading of the description, this command line should trigger the problem?

$ ls -l foo 
ls: cannot access 'foo': No such file or directory
$ curl curl.se -c foo -b foo -o /dev/null

Hello @bagder ,

We observe a similar issue (but a memory leak) with CURLOPT_COOKIEFILE in combination with curl_easy_reset.
In a recent change af5999a, there was an update to move cookies from data->state to data->set.

However, curl_easy_reset performs a non-conditional memset on data->set, however, the documentation was not updated

It does not change the following information kept in the handle: live connections, the Session ID cache, the DNS cache, the cookies, the shares or the alt-svc cache.

I believe that curl_easy_reset shall not cause a memory leak and must either

do not call memset;
or store-and-restore cookie data to-from a temp variable.

Best regards,
Sergey

I believe that curl_easy_reset shall not cause a memory leak and must either

does this solve it

(edit: patch moved to #10709)

bagder · 2023-03-08T12:53:01Z

That was a memory-leak and thus a different matter and issue than what is reported here.

And make sure there is no memory leak Ref: #10694

Keitagit-kun · 2023-03-08T17:12:39Z

There some relation with verbose mode...
It in FreeBasic, but still reproduse crush:

- Free set.cookelist in Curl_freeset instead of Curl_close. Prior to this change the cookielist linked list wasn't freed by curl_easy_reset which calls Curl_freeset to free all set. Bug: curl#10694 (comment) Reported-by: Sergey Ryabinin Closes #xxxx

And make sure there is no memory leak Ref: curl#10694

Keitagit-kun · 2023-03-09T20:32:32Z

another addition - if I move deallocation of userdata Delete ptInfo to line after curl_easy_cleanup(cURLHandle) like that:

	Print "> CleanUp - 0"
	
	curl_slist_free_all(cURLSList)
	Sleep(1000,1)
	Print "> CleanUp - 1"
	
	curl_easy_cleanup(cURLHandle)
	Sleep(1000,1)
	Print "> CleanUp - 2"
	
	DeAllocate(cURLErrorBuffer)	:	cURLErrorBuffer = 0
	Sleep(1000,1)
	Print "> CleanUp - 3"
	
	Delete ptInfo
	Sleep(1000,1)
	Print "> CleanUp - 4"

Then there a no crush and cookiefile is created.

--> Connection Log End :
> CleanUp - 0
> CleanUp - 1
> CleanUp - 2
> CleanUp - 3
> CleanUp - 4
--> Done

I dont understand...
as side note - I applied memleak fix and there a no change...

bagder · 2023-03-09T22:16:55Z

I'm sorry, but I'm gonna need a recipe that uses libcurl directly or the command line tool. No binding.

Keitagit-kun · 2023-03-09T22:47:29Z

well... i'm don't know C and dont have any means to work with it... but maybe this give some light to the problem:
first - I changed function like this:

Public Function MainDebug2() As Long Export

	' ........................................................................................
	Print "--> Done"
	' ----------------------------------------------------------------------------------------
	'
	' ----------------------------------------------------------------------------------------
	return 0
End Function

and callback to this:

Function cURLCallbackFunc_DebugTraceFuncEL Cdecl(ByVal handle As CURL Ptr, ByVal itype As curl_infotype, ByVal idata As ZString Ptr, ByVal iSize As size_t, ByVal zBuffer As tagcURLCallBackBuffer Ptr) as Long
	
	Select Case As Const itype
		
		case CURLINFO_TEXT, CURLINFO_HEADER_OUT, CURLINFO_HEADER_IN
			
			Dim As ZString Ptr buff = CPtr(tagcURLCallBackBuffer Ptr, zBuffer)->strbuf
			
			Print ">> 1-0 ";zBuffer,zBuffer->strbuf
			Print ">> 1-1 ";zBuffer->size,iSize
			Print ">> 1-2 ";zBuffer->allocated
			
			Clear(zBuffer->strbuf[zBuffer->size],0,iSize + 1)

			Print ">> 2-1 ";zBuffer->size,iSize
			Print ">> 2-2 ";zBuffer->allocated
			
	End Select
	
	Return 0
End Function

and get this output:

--------------------------------------------------------------------------------------------
--> Connection Log End (2) :

now if Imove deallocation of user pointer to before curl_easy_cleanup() function like that:

Delete ptInfo

	Print "> CleanUp - 0"
	
	curl_slist_free_all(cURLSList)
	Sleep(1000,1)
	Print "> CleanUp - 1"
	
	curl_easy_cleanup(cURLHandle)
	Sleep(1000,1)
	Print "> CleanUp - 2"
	
	Print "--> Connection Log Start (2) :"
	Print "--------------------------------------------------------------------------------------------"
	Print *ptInfo->strbuf
	Print "--------------------------------------------------------------------------------------------"
	Print "--> Connection Log End (2) :"
	
	
	Sleep(1000,1)
	Print "> CleanUp - 3"
	
	curl_global_cleanup()
	Sleep(1000,1)
	Print "> CleanUp - 4"
	' ........................................................................................
	Print "--> Done"

then I get:

You can see that debug func was called in curl_easy_cleanup(), outside curl_easy_perform()
and to that moment pointer of string buffer changed (as it was deallocated)
So answer to problem is simple:
up to curl 7.86 curl_easy_cleanup() did not called debug func, and now it do so - see
second WARNING: failed to open cookie file "C:\Temp\_CookiesFileInQuestion.txt" line
in first log.
To summ it up: to counter crush user pointer should be deallocated strictly after call to curl_easy_cleanup()
I think it should be menthioned in docs.

Thanks.

I cleaned up your most recent C example and was able to use it to reproduce with curl-7_88_1. (Click to expand)

			memcpy(&zBuffer->strbuf[zBuffer->size],idata,iSize);
			zBuffer->size += iSize;
	}
	
	return 0;
}

int main(void)

	curl_global_cleanup();

  OPENSSL_cleanup();
  _CrtMemDumpAllObjectsSince(NULL);
  printf("\n");

  return 0;
}

The crash is because the memory used by your debug callback is freed before calling curl_easy_cleanup. As long as DEBUGFUNCTION is set then any curl_xxx function that operates on the handle may call it. As you've already figured out, when you free the memory after curl_easy_cleanup then there is no crash. However, your original example in VB code seems to show that you already do that...

Can you confirm that there is no crash in your actual code if you free the memory after curl_easy_cleanup?

Note the C example will crash with curl-7_88_1 but not with master (674a066 2023-03-10) because 45d4bf5 changed the behavior not to re-read the cookie files on cleanup so there is no verbose text (like file not found etc) when that happens. Even though it doesn't crash that's just by chance. It still may crash if you free the memory before curl_easy_cleanup.

Keitagit-kun · 2023-03-12T15:48:01Z

Yes, there is no crash if i free memory after curl_easy_cleanup().
Thanks
