Re: [libvirt] Two core dumps are generated in multi-thread scenarios
Hi,
Old code(in esx_vi.c) is as below:
curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx");
curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0);
New code:
curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1);
curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx");
curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0);
B.R.

Hi,
I found two core dumps generated in multi-thread scenarios in ESX part.
Case1: libcurl support multi-thread
core dump:
#12 0x00002aaabea89712 in addbyter () from /usr/local/lib/libcurl.so.4
#13 0x00002aaabea89b86 in dprintf_formatf () from
/usr/local/lib/libcurl.so.4
#14 0x00002aaabea8b055 in curl_mvsnprintf () from

#15 0x00002aaabea7678f in Curl_failf () from

/usr/local/lib/libcurl.so.4
#17 0x00000006e8a8f230 in ?? ()
Fix code:
esxVI_CURL_Connect() in esx_vi.c:
I add a new line as following:
curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1);
Where exactly in the function ? Can you send a diff of your change ?
