From the Valgrind output, it looks like there's a problem with freeing sockets in a non-expected way. The user mentioned that after a transfer is done (CURLMSG_DONE), the socket gets freed, but then curl_multi_do() is called again for that same socket. - -Hmm, so maybe the issue is that QEMU is incorrectly handling when to free the socket. Libcurl might expect that the socket isn't freed until it explicitly signals, perhaps through another message or callback. The user suggested that QEMU shouldn't free the socket just because a transfer is done but should wait for libcurl's explicit instruction. - -Looking at the patches they provided, it seems like they adjusted how the sockets are managed. Instead of freeing them immediately after a transfer completes, they now only remove the socket when told by libcurl. That probably prevents the double-free or using a freed pointer issue that was causing the segfault. - -I think the main takeaway is that QEMU needs to align its socket handling with libcurl's expectations, ensuring that sockets are only freed at appropriate times based on libcurl's callbacks and messages rather than assumptions about when transfers complete. -</think> - -The problem arises because QEMU frees a socket too early after a transfer completes, leading to an invalid state when `curl_multi_do()` is called again. The solution involves adjusting how QEMU manages these sockets: - -1. **Avoid Premature Freeing**: Don't free the socket immediately upon receiving `CURLMSG_DONE`. Instead, wait until libcurl explicitly signals that the socket should be removed. - -2. **Use Libcurl's Instructions**: Only remove the socket when libcurl's callbacks or messages indicate it's safe to do so, preventing the use of a freed resource. - -**Steps Taken to Resolve:** -- Modify QEMU's code to handle socket management based on libcurl's explicit instructions. -- Implement patches that ensure sockets are only removed after libcurl signals they're no longer needed. - -**Outcome:** -The segfault was resolved by correctly managing the lifecycle of sockets in QEMU, aligning with how libcurl expects them to be handled. \ No newline at end of file |
