HAProxy - Load balancer
234a10aa9b
In htx_xfer_blks() function, when headers or trailers are partially transferred, we rollback the copy by removing copied blocks. Internally, all blocks between <dstref> and <dstblk> are removed. But if the transfer was stopped because we failed to reserve a block, the variable <dstblk> is NULL. Thus, we must not try to remove it. It is unexpected to call htx_remove_blk() in this case. htx_remove_blk() was updated to test <blk> variable inside the existing BUG_ON(). The block must be defined. For now, this bug may only be encountered when H2 trailers are copied. On H2 headers, the destination buffer is empty. Thus a swap is performed. This patch should fix the issue #1578. It must be backported as far as 2.4. |
